When selecting a shear, many people assume that hydraulic operation is a better option as they equate it with a press brake. However, shearing is a completely different process and mechanical actuation can actually be preferable for a shear due to the following factors.

 

Where Mechanical Shears Excel

  • Speed: Mechanical shears are faster in full cycle mode.
  • Shock Resistant: Heavy castings and frames absorb the snap of the shearing process better than hydraulic cylinders.
  • Simplicity: Mechanical shears have simpler mechanisms to maintain and repair making up time longer and downtime shorter.
  • Noise: Mechanical shears are quieter as they do not have the constant running of hydraulics.
  • Heat: Without hydraulics mechanical shears run much cooler
  • Green: No hydraulic oil, hydraulic heat (requiring cooling), hydraulic oil waste, or filter waste.

 

Where Hydraulic Shears Have an Advantage

  • Variable Stroke Length: Mechanical shears must make the full cycle when shearing whereas hydraulic shears can be set to perform quick, short strokes—which is useful when shearing material that is only a few inches in width.
  • Overload Protection: Because it’s protected by a blowout valve, a hydraulic shear can stop the blade from getting into a “locked” position with the material. Basically, when the hydraulics reach the maximum PSI for the shear, a safety valve opens up and dumps the high pressure hydraulics—stopping the downward force and thus allowing the ram to be backed off and the oversize/hard/obstruction to be removed.
  • Price: Hydraulic shears are inherently cheaper to build.

 

Common misconceptions in shearing assume that hydraulic shears are “safer.” While hydraulic shears can be stopped in a cycled down stroke, so can a mechanically actuated system. The difference is that hydraulic shears can be automatically reversed when stopped, whereas mechanical shears cannot. When protected by proper guarding and light curtains as necessary, a mechanical or hydraulic shear can be a great addition or compliment to your fabricating process.

 

If you want to get more information of hydraulic shears, welcome to visit Yeh Chiun Industrial Co., Ltd. – they are the professional manufacturer of specializing in high-quality press brakes. To get more details of shearing machines, please do not hesitate to contact with Yeh Chiun.

If you are into the business of cutting or reshaping metals and wood and are confused if the band saw machines will work for you this write-up is for you. Read on to know more.

 

Band Saw is a cutting machine that has several metal teeth and blades and is used to cut metals as well as wood that cannot easily be cut using a table saw or any other thin blade saw. Because of its wide area of application, band saw machines are used by various experts including furniture and artefacts manufacturers.

 

Benefits of Using a Band Saw Machine:

 

  • Decorative Furnishings: Decorative furnishings have been in demand since time immemorial and will continue to remain so owing to human’s affinity to arts. If you are a furniture manufacturer and manufacture of small wooden artefacts, then an automatic band saw will help you more than a table saw as it works faster and cuts finer.

 

  • Metal Cutting: Metal cutting is another important industrial use where a band saw machine comes to use. For cutting thin metal sheets such as aluminum to making thick metallic plates of steel, a band saw cutting machine is ideal for use as it uses various kinds of blades to cut at various levels of depths.

 

  • Lesser Wood Loss: A table saw will generally result in a lot of wood sand which is nothing but wasted wood. This is because a table saw has a thicker blade than a band saw machine and thus if you want the least wastage of raw materials while manufacturing you need to buy an automatic band saw machine.

 

  • Speed: A band saw machine not only uses finer blades it also uses machines and motors that accelerate the process of cutting the object. Just like a chainsaw uses a chain to rotate its blades, a band saw uses motors to run the blades, and thus, cutting is speedy and more convenient.

 

  • Accuracy: A band saw machine gives the most accurate cutting when compared to a cut made using any other cutting machine. This is because of the various kinds of blades the band saw machine uses as well as the different planes over which a band saw machine can make an incision.

 

  • Fencing: When making fences, wooden or metallic, a band saw machine is an ideal cutter to use because it gives the most precise straight cut possible and thus gives desirable straight fences.

 

Band saw machines are in high demand because of the application it has in various industries ranging from a small wood cutting industry to a giant metal cutting industry. If you too are looking to buy a band saw machine for your business make sure to check the online marketplace beforehand to get the best deals.

What Will The Manufacturing Landscape of Tomorrow Look Like?

Will human workers be replaced by robots? Will 3D printing become the dominant production technology? Will all of our sugary treats be manufactured in Mexico?

 

Whatever the case, Industry 4.0—the catchall term for the trend toward automation and big data in manufacturing—is coming and manufacturers the world over is doing their best to prepare.

 

At this year’s IMTS, leaders from Taiwan’s machine tool industry plan to unveil a series of smart manufacturing initiatives during a press conference to illustrate part of the county’s overall efforts toward Industry 4.0.

 

Presenters will include representatives from the Taiwan Association of Machinery Industry (TAMI), the Industrial Technology Research Institute (ITRI), and the e-Manufacturing Research Center at National Cheng Kung University and Taiwanese machinery manufacturers, including Fair Friend Group, Luren Precision and Tongtai Group.

 

These initiatives are intended for applications including aircraft component machining, automotive part production, gear grinding and finishing, automation and more. Specific details are sparse, but the five topics to be covered in the press conference offer hints at how Industry 4.0 will impact machine tools.

 

  • Cross-Sector Collaborations

Cooperation between academics, industry professionals and researchers will be vital to ensuring that manufacturers are on the cutting-edge of new technologies. For this reason, the presenters will discuss their plans for collaboration among Taiwanese educational institutions, research institutes and machinery companies in an effort to advance the country’s smart machine and manufacturing capabilities.

 

  • Enhanced Metrology

One of the largest impacts big data will likely have in manufacturing is in quality assurance. The ability to leverage huge amounts of information about a product and the processes used in its manufacture could revolutionize the quality profession. To that end, the presenters will discuss plans for an automatic virtual metrology (AVM) real-time, online inspection system. The AVM system is intended to eliminate the delays of offline sampling inspection and advance one of manufacturing’s ultimate goals: zero defects.

 

  • Improved Human-Machine Interfaces

Futurology predictions aside, manufacturing professionals are not going to wake up one day to find themselves replaced by robots. Many machining processes will continue to require immediate human input for years to come. That’s why the presenters will emphasize gear grinding and finishing machines that generate NC code automatically after data input. This will enable technicians to change input data settings via TeamViewer or Skype. These improve HMIs can also accommodate automatic loading and unloading via robot (but don’t read too much into that).

 

  • Revamped Production Lines

Advancements in specific aspects of manufacturing, such as quality assurance or human-machine interfaces, are certainly an important part of Industry 4.0. However, the key idea behind the Industry 4.0 concept is the integration of all the various aspects of manufacturing into so-called “factories of the future.” At the IMTS press conference, leaders in Taiwan’s machine tool industry will highlight their plans for new production lines that will include integrated robot control, real-time remote monitoring, quality traceability and more.

 

  • New Machining Centers

It’s only natural that the leaders of Taiwan’s machine tool industry would announce new machine tools, in addition to these other four initiatives. The presenters will showcase new 5-axis horizontal machining centers that are reportedly 20 percent more productive and 20 percent more cost-effective for manufacturing aerospace engine casings compared with previous generations.

5 Accessories Every Compound Archer Needs

On October 3, 2018, in Manufacturer, Sport, by Jasmie K.
0

Whether you just bought a new bow or simply want to give Ol’ Reliable a facelift, you’ll have fun outfitting your compound bow with accessories to improve its performance. To stack more arrows into the bull’s-eye than you ever thought possible, visit an archery shop and study your options for the accessories below.

 

  1. Sights

Sights are the one piece of gear you focus on every time you draw your bow. You can make an old bow feel new again by upgrading your sights. If you’ve bought a new bow, don’t skimp on your sight.

 

Many options are available in multi- and single-pin options. Multi-pin sights come in three-, five- or seven-pin options, and are ideal for keeping your setup simple and foolproof. Sight in each pin for a different yardage – usually 10 yards per pin – and you’ll be ready to shoot. Single-pin “slider” sights are more precise because they let archers dial the pin to the exact yardage and then hold where they want to hit.

 

  1. Release-Aids

A quality release-aid promotes consistent shots and tighter groups. Choose between a handheld thumb-button release or a wrist-strap trigger-finger release. Handheld thumb releases help some archers cure target panic, a psychological problem that prevents archers from holding their sight-pin on target. Wrist-strap releases remain strapped to your wrist, which helps you execute quick shots.

 

To decide which model is right for you, make sure you understand the pros and cons of each model, and that you’re comfortable using it. If you choose a wrist-strap release, consider a model that secures with a buckle strap. The buckle ensures your release attaches to your wrist at the same location each time.

 

  1. Rests

Your shooting preferences dictate the best arrow rest for you. If you often take long-range shots, buy a drop-away rest. When properly tuned, drop-away rests hold your arrow in a consistent position at full draw, and drop away from it almost instantly when you release. That ensures your rest won’t affect the shot.

 

If you don’t shoot long distances and simply want a quality rest that secures your arrow in place, look for a biscuit-style rest. These affordable rests deliver tack-driving accuracy for shots out to 40 yards.

 

  1. Wrist Slings

Gripping your bow loosely throughout the shot might be archery’s most difficult technique to master. Your grip is important, because most shooter-caused accuracy problems start there. If that’s a problem, consider a wrist sling, which lets you gently hold your bow throughout the shot without worrying it will fall when you release your arrow. When you consistently grip your bow loosely and comfortably, you’ll become much more accurate.

 

  1. Quivers

High-quality quivers do much more than hold your arrows, especially if they attach to your bow. Most modern quivers mount tightly to the bow’s riser, which helps balance your bow at full draw. Some mounting brackets quickly adjust the quiver higher or lower by simply flipping a lever. Even if you shoot without your quiver attached to your bow, quality models still hold your arrows securely, keeping them handy for shooting and organized for traveling.

 

Conclusion

Bow accessories let you customize your bow to your needs. Besides being practical, quality accessories make for fun visits to archery shops as you seek ways to improve your setup. Whether you want to rejuvenate your old bow or deck out a new bow with all the best gear you can afford, choosing the right accessories can improve its looks, feel and performance.

 

If you need more choice of archery bow accessories, come and visit Man Kung Enterprise Co., Ltd. – they are the manufacturer of specializing in a variety of archery products. To get more details, welcome to check out their site and feel free to contact with Man Kung.

For decades, piston pumps have been used to meet a wide variety of transfer, extrusion, coating and dispensing requirements across many industrial and commercial applications. The versatility of piston pumps makes them a workhorse in everything from pressure washing, abrasive blasting, bonding, chemical dosing, potting, paint spraying, lubrication and pavement marking to sanitary dispensing, to name a few. With this versatility in mind, the fluid type and viscosity of the material being transferred—and the associated flow rate and output pressure for those materials—must be considered to ensure that the correct pump is selected for the application.

 

A piston pump is classified as a reciprocating positive displacement pump that uses a piston or plunger to draw and move fluid through a sealed cylinder.

 

The fluid inlet of the piston pump is often immersed directly into fluid, which is then drawn into the pump via negative pressure as the plunger reciprocates. The combination of check valve timing and plunger motion allows fluid to be dispensed on both the up and down stroke, delivering output pressures up to 15,000 per square inch (psi) and flow rates up to 60 gallons per minute (gpm).

 

Piston pumps are powered by a variety of motor types including pneumatic, hydraulic and electric.

 

Pneumatic motors are the most common choice due to their reliability, ease of maintenance, good power density, stall capability without motor damage and inherent safety in volatile atmospheres.

 

Hydraulically powered pumps offer even better power density than pneumatics as well as quieter operation. Hydraulic piston pumps tend to be the preference for mobile applications where the power take-off (PTO) of a vehicle can be used, or when working in cold conditions where motor icing could cause challenges. Piston pumps powered by an electric motor are energy efficient, but because of low power density, an electric pump cannot deliver the pressures that many industrial applications demand, limiting use to lower viscosity fluids and applications mostly involving transferring or spraying.

 

Application Pump Types

Multiple pump ends are available for piston pumps to successfully handle a range of fluid properties. These are called lower-ends and they are available in two-ball, four-ball and chop-check types. Two-ball and four-ball style piston pumps are designed for low to medium viscosity fluids typically found in transferring, washing and coating applications. For extrusion applications involving high-viscosity materials up to and beyond 1 million centipoises (CPS), both heavy-duty chop-check and two-ball pump packages can be used.

 

Demanding extrusion tasks often require additional accessories such as a pneumatic ram assembly and a follower plate to provide additional force to move the fluid into the pump, thermal blankets to reduce material viscosity or fluid regulators to ensure accurate dispense control.

 

Although there is a measure of capability crossover, each piston pump type has limits. It is advisable to consult the manufacturer or dealer when sizing or selecting a pump for a specific application.

 

Handling Sticky Situations

When using a piston pump to transfer challenging media such as shear sensitive ultraviolet (UV) inks or adhesives with suspended solids, special tubes and plunger coatings and packing seal materials are used. These minimize shear and thermal energy, as well as provide resistance to any abrasion that can occur. A stainless steel pump combined with ceramic-coated cylinders and piston rods offer waterborne benefits and abrasion resistance for more endurance and reduced wear when working with harsh materials. All of these features combined help prevent premature pump failure.

 

Understanding the fluid and the ultimate goal of the application is essential to maintaining product integrity. Some fluids require shear control or thermal assistance to get them to a viscosity at which they can be transferred easily while minimizing the risk of irreversible fluid damage.

 

Shear-sensitive materials are diverse and cover everything from lotions and soaps to pastes, cornstarch, inks, some adhesives and certain paints.

 

Such materials require low internal velocities and gentle pumping action to limit damage and maintain their properties during transfer applications. In the microelectronics industry, many sealing compounds include the addition of fillers for enhanced performance.

 

This results in a mix of solid and viscous properties that can present challenges in effectively managing the application without damaging the pump or material.

 

Piston Packages

With so many variables at play, application packages preconfigured with the right motor, piston pump, mount, controls and accessories offer operators the greatest flexibility. For end users, pre-assembled and validated application packages eliminate much of the guesswork that comes with choosing the right pump for the job.

 

Challenging adhesives such as multiple component or glass-filled sealers require stainless or carbon steel piston package options with coated tubes and plunger rods to tackle difficult extrusion and transferring applications. When it comes to new or unique applications, it is recommended to refer to the pump manufacturer’s viscosity and chemical compatibility resources or consult with an expert to properly configure the package.

 

What’s On the Inside Counts

The way a piston pump is designed and engineered impacts its functionality and performance when in use.

 

With a simple motor design, universal valve blocks and pump connections, piston pump operators can easily move between motor sizes, create new pump ratios and even upgrade their system without buying a new pump. Other features include:

 

  • a progressive exhaust motor design to minimize icing
  • adjustable packing seals and optional component coatings to improve pump life
  • quick disassembly for easy maintenance
  • thermal relief kits to prevent over pressurization

 

All of these characteristics make piston pumps a widely used and multipurpose option for accurately moving fluid.

 

Maintaining & Extending Piston Pumps

Because it has only a few moving parts, maintaining a piston pump is relatively simple. When cleanliness, cycle rate and other wear factors are monitored and controlled, a piston pump can last for many months or even years between maintenance cycles. For maximum pump and system component life, piston pumps must be protected from contamination.

 

Proper pump cleaning should align with frequency of use and the fluids being pumped. This is particularly important for corrosive chemicals, in which case it is advisable to flush your pump with a neutralizing solution followed by a clear water rinse after each use.

 

While features such as coated plunger rods and tubes and PTFE or ultra-high molecular weight polyethylene (UHMW-PE) packing options can extend pump life, packing seals are designed to wear and still require routine monitoring and replacement.

 

Flow rate, application requirements and fluid type all help predict the frequency of regular maintenance replacements however, indicators such as fluid in the solvent cup, pressure loss or uneven pump cycling also serve as service markers.

Does it bug you when people misuse terms, saying something like “cement” when they really mean “concrete?”

 

Hoists and cranes are both machines that help move and lift heavy loads on the job site, but they have many fundamental differences in design and usage.

 

Below, we set the record straight about what each of these devices does, and how they work together to assist in your next project.

 

Crane vs. Hoist: What’s the Difference?

First things first – a hoist helps to do one thing: move heavy loads up and down.

 

An elevator is probably the most well-known hoist. Elevators are the perfect machine for transporting loads vertically, but in no other direction (unlike a crane’s functionality).

 

On the other hand, a crane can move in two or three dimensions. Overhead cranes suspend from a beam or move along a rail.

 

Just like cement is a component of concrete, a hoist is a central part of an overhead crane. Essentially, the crane moves the hoist around.

 

Types of Hoists

Hoists are defined by their lifting medium, power, and suspension.

 

Lifting Medium

The lifting medium is the flexible material that connects the load hook to the overhead body of the hoist. It can be either a rope, metal cable, welded link chain, or roller load chain.

 

  • Welded link chain, like an anchor chain, is a series of identical metal loops attached together to form a string.
  • Roller load chain, like a bike chain, is made from alternating roller links and pin links to form a line that easily engages with a toothed sprocket.

 

Power

Hoists can be powered manually, electrically, or pneumatically. Manual hoists use a pulley to multiply the operator’s pulling force.

 

You can also use electricity or air power to actuate a hoist motor. Choose what’s easiest to access. Factories with many air tools might find air power more convenient.

 

Suspension

The suspension method for a hoist depends on how it will be used.

 

A stationary hook-mounted hoist is a simple solution when you only need to move a load straight up, such as from a truck to a trailer. Meanwhile, a hoist bolted to a beam will handle heavier loads.

 

A hoist can be mounted to a trolley running along a beam or a rail, giving you the ability to lift up then across the facility.

 

Gantry cranes give you three-dimensional motion. You can lift up, move the hoist along the gantry rail, then move the crane itself wherever you need it.

 

Types of Overhead Cranes

The type of crane you have determines what your hoist will do for you. Some of the most common overhead crane types include:

 

Top Running Crane

The bridge moves atop a pair of rails mounted to the ceiling, allowing for heavy loads to be lifted and moved.

 

Under Running Crane

The bridge travels along the bottom flange of two beams. Certain buildings’ construction might require this type of crane for your project.

 

Gantry Crane

A single or double girder attaches to a pair of broad legs with wheels, enabling the crane to operate without being attached to the ceiling. These are popular cranes in shipbuilding.

 

Monorail Crane

The hoist attaches to a trolley on a single rail that follows a path around the facility in an oval or snaking path. This is effective for moving around a complex space.

Most types of valves will require one of two types of actuators to use: the spring return (also known as the single acting) actuator and the double acting actuator.  While there are a variety of other types and categories of actuators, these two are the most important and are frequently the go-to choice for use in facilitating the operation of a great variety of machines and industrial mechanisms. But how do you know which one is right for you?

 

Knowing the Difference Between Spring Return and Double Acting Actuators

 

The defining characteristic between these two style actuators can be found in their names; a spring (single) actuator supplies power for one direction of its working range while the double actuator supplies power for both working directions. This is because the spring actuator utilizes spring force to move the valve position to either open or close. In contrast, the double acting actuator utilizes a piston element to operate that valve and thus will require pressurization on both of its sides.

 

Picking the Right Actuator for the Right Application

 

  • When going for torque or thrust strength: While some sources believe that both types of actuators have equal strength capabilities when it comes to thrust and torque, we do recommend taking a hard look at your needs before making a hasty decision. The spring actuator’s design makes it ideal for situations where the torque load is experienced on only one side, at the activation stroke. In contrast, the double acting actuator works great in situations where there are high torque loads in both its working directions and when there is a high thrust strength, such as in many oil and natural gas applications.
  • When needing safety assurances: When it comes to safety system applications where immediacy in shutdowns and fail safes are of utmost concern, then it is always best to for the simplest option. Here, this means go for the spring return valve actuator due to its design simplicity and reliability.
  • When the valve needs to fail in last position. There are a variety of applications where it is necessary to have a valve to fall in last position when it loses its signal or supply. The double acting actuation works best in these types of applications as it’ll use pressurization on both of its size to keep the valve held safe and secured in last position.

 

Final Take-Away

In the end, the most important thing to take away is that neither the single return actuator nor the double acting actuator is a one-stop solution for all applications.  Each of these actuators has a unique design that makes it ideal for some, but not all uses. But no matter which one you choose, these actuators are generally considered easy to install and most are built for a long and reliable service.
