摘要： An hydraulically operated down-stroking press comprises a C-frame (10) with an upper arm (19) provided with punch mounting means (58), and a lower swingable arm (14) for supporting an anvil. The lower arm (14) can be swung away to allow a further anvil support (24) to be suspended from a mount (26) on the upper arm (19) and so to allow the press to operate on relatively small workpieces of different shape.

摘要： A ram for a press, comprising an hydraulic piston and cylinder arrangement (10,22) which is operated by the application of pressure to hydraulic fluid in a region of the hydraulic chamber (16) within the cylinder (10) which is on one side of the piston (22). Hydraulic fluid is free to flow into and out of the said region until the hydraulic piston (22) nears the end of its stroke. The bottom end (44) of the chamber (16) is narrowed, to cut off such flow at that point, so that subsequent application of pressure to the hydraulic fluid in the said region effects a movement of the hydraulic piston (22) under the full operating force of the arrangement (10,22).
