ABSTRACT:
An improved adapter cushion is used in a press with a die assembly having a plurality of projecting die pins. The adapter cushion includes a one-piece cylinder block in which a plurality of cylinder chambers are formed. Cylinder sleeves or liners are telescopically disposed in the cylinder chambers and are connected with the one-piece cylinder block by threaded connections. Replaceable tubular guide bushings are disposed in the end portions of the sleeves to guide relative movement between the die pins and the cylinder block. In order to provide a yieldable support for the die pins, pistons are urged toward axially outer ends of the sleeves under the influence of fluid pressure. During operation of a press, the die pins work against the fluid pressure acting on the pistons. In order to facilitate utilization of the adapter cushion with different types of dies, a cylinder sleeve can be readily removed and a cylinder plugged without disassembling the adapter cushion. Noise reducing resilient bumpers are advantageously mounted on the pistons.
