Hydraulic Workholding System Washington DC

Provided by:

The foundation for effective hydraulic workholding is built on component selection and system connection. Whether the system is simple or complex, the job at hand is basic or sophisticated, there are four simple steps comprise the selection and installation of a hydraulic workholding system.

Cylinder selection

Proper cylinder selection is the most critical factor in any workholding system. The shape and size of the workpiece and the machining process involved will determine the type and size of cylinders most suitable for the job. A range of production tooling cylinders are available for various tasks:

Positioning and push cylinders guide the workpiece and push it securely into the desired position.

Down-holding cylinders, including swing cylinders and edge clamps, clamp the positioned workpiece firmly to the fixture or worktable.

Pull cylinders, some available with hydraulic or spring return, clamp the workpiece or fixture in applications requiring pull forces.

Work support cylinders maintain the workpiece accurately on the prescribed plane during machining.

Swing cylinders and work supports often are used in combination for a variety of workholding applications. Swing cylinders typically are used as clamping components in applications requiring unrestricted loading and unloading. Providing maximum clamping force in a small package, they enable unobstructed part fixturing and placement.

A swing cylinder's rod and attached clamp arm rotate 90 degrees in clockwise or counterclockwise directions, then travel down an additional distance to clamp against the fixtured part. When the clamping pressure is released, the clamp arm rotates 90 degrees in the opposite direction to allow for part removal and new-part placement.

Different mounting options and operation styles enable users to select components to suit almost any application. Varieties include upper- and lower-flange swing cylinders, as well as threaded-body and cartridge-model swing cylinders. Different sizes and styles of clamp arms also are available.
