A pneumatic swing cylinder is a hydraulic workholding device that allows the clamping arm to be swung away from the working area during the retraction stroke, and can be locked in position when needed.8.pneumatic swing cylinder This type of cylinder is ideal for applications that require low clamping force and keeps the workspace free of clamping components and straps for unobstructed loading and unloading of the work-piece. It is available in a single- or double-acting version. In double-acting versions, the piston and piston rod assembly rotates by a given angle in one direction during the stroke and then reverses rotation to return the clamping arm to the starting position.

This type of cylinder is suitable for a wide variety of clamping applications because it is easy to operate and provides high lateral force.8.pneumatic swing cylinder It can be equipped with either a manual or automatic pressure release mechanism. In automatic mode, the pressure is released at a preset time after the end of the clamping stroke. In manual mode, the pressure is released by manually turning the valve to open the piston rod. It can be supplied with an optional pressure sensor that provides feedback to the control system and ensures that the hydraulic pressure remains within the specified range.

Cylinder selection depends on a number of parameters, such as the size and shape of the clamping area, maximum rated hydraulic force, and the clamping force that can be transmitted by the clamping arm. To transmit the required force, clamping arms are available in a wide variety of shapes and sizes. Some are machined from solid stock, while others can be customised according to customer requirements.

In conventional hydraulic workholding, the maximum force is applied to the cylinder through a wedge that mechanically locks the cylinder plunger inside the chuck of a collet. The wedge is driven upward by hydraulic pressure from a lower port, and the cylinder plunger can be removed only when hydraulic pressure is applied to the opposite side of the wedge via an upper port. Enerpac's Collet-Lok system offers this same positive clamping, but eliminates the need for special valving or a continuous power source for maintaining pressure.
