To hold a workpiece in place as machining is carried out, pneumatic clamp cylinders are used. What is special about them is that these cylinders use air actuation to perform the clamping process. They are suitable for rapid clamping in routine manufacturing processes, but they are compact and inexpensive to use for temporary repairing on short-term workers. Many pneumatic clamp cylinders are designed for the long-lasting weld to spatter resistance.
For workholding fixtures for drilling, grinding and other machining activities, a pneumatic clamp cylinder clamping device is suitable for setups, and can be used in a work cell for several devices. A no resetting, palletized workpieces may be moved from one workstation to another.
The device consists of stationary components directly assembled individually or in multiples on the work table or tombstone of a computer. Current workholding accessories are mounted on the clamping surfaces, such as visors, chucks, or special fixtures, and mated to the components.
A filter-regulator, pneumatic four-way valve, clamps, fittings, and pipes are common pneumatic clamp cylinders. Depending on the program and user choice, the type of control-valve actuator, a basic manual or solenoid-operated actuator is in most situations very necessary.
For multi clamp systems, a neater, more-efficient device is given by manifolds. Since the clamping cylinders are double-acting, that is, air expands and retracts them, traditional systems require two manifolds, one for clamp opening, the other for clamp closure. All the assembly hardware needed is lightweight tubing and push-in fittings for many applications. Tie-rod fixed tubes and steel piping are used in many clamps.
A pneumatic clamp cylinder fitted with a magnetic ring on the piston may be used for computer-controlled devices. Placed on the outside of the cylinder, Reed or Hall-effect switches detect the open or closed state and transmit the information back to the controller so that the next step in the process will begin. For the machining application, the effect is reliable, rapid part clamping. The operator is more efficient and will increase throughput to satisfy demand should the need occur.
Compared to hand clamps, pneumatic clamp cylinders have the following advantages: the user doesn't have to constantly perform clamping. Several clamps can be triggered simultaneously and can be closed in a particular sequence. Single or multiple clamps can be activated by computer control or hand control from various locations. Even if the air supply fails and the air intake is low due to the high final ratio, the clamp stays closed. Finally, a broad opening direction is reached by pivoting the clamping arm and ideal force and movement ratios are achieved.
Let us take an example of certain variables for the pneumatic clamp cylinder solution: welding applications. Worker ergonomics plays a growing role in the construction of fixtures and will continue to be a priority for future projects. It's a big challenge to recruit and maintain good welders and enterprises are trying what they can to satisfy and retain their welders.
If the weld fixtures and tooling are simpler to load, clamp, unload, and unclamp, the welders would not only be more efficient but your staff working atmosphere will be better, and in turn your employees will be happier, stronger, better, and will have a greater chance of staying around. Therefore pneumatic clamp cylinders are ideal to increase the ergonomics of your machine and increase the work efficiency of your operators.
Ergonomics of Pneumatic Clamp Cylinder
In some areas, clamping can play a significant role in the ergonomics of welding fixtures. Pneumatic clamp cylinders can simplify the clamping process. It can be physically exhausting to manually clamp and unclamp sections and can inflict long-term injuries, whereas pneumatic clamping promises improved ergonomics for staff. Wide welding fixtures that require manual actuation will also present ergonomic and safety challenges depending on the scale of the weld and fixture.
Pneumatic clamp cylinders are also ideal for automated clamping mechanisms. If everything is an automatic movement the accuracy increases. With manual clamping, therefore there seem to be more moving parts and hence less overall reliability. That said the sort of manual clamp used is more of a factor in longevity.
Clamps constructed with stampings, for example, can wear much faster than clamps constructed with forged parts. Low-quality clamps with uncovered rods and those built with stampings would be less reliable with pneumatic clamping than fully sealed automobile grade clamps.
The bottom line on clamping reliability of pneumatic clamp cylinders as well as in general, is to realize that the clamping process may not play as big a part as the clamp consistency used. When deciding the clamp construction and reliability, a lot of the projected annual use of time plays a major role. To weld twenty thousand parts a year, you don't want to use a low-budget clamp, but you don't want to use fully sealed automotive-grade clamps to weld three hundred parts a year either.
