Abstract: The upper platen of a press is driven by a ballscrew that is rotated by an electric motor. The ballscrew is suspended from the crown of the press, and the force on the ballscrew shaft when the upper platen is driven into the workpiece causes the crown to flex upward. The flexure of the crown is sensed by a position transducer mounted on a cantilever support. The position transducer generates a signal that can be used to determine the tonnage force developed by the press.

Abstract: A mandrel assembly is utilized to cold work a hole in a structural member which is present in a confined area. A mandrel and sleeve are slipped through one end of the hole. The mandrel length is threaded so that a nut may be turned along its length. Between the nut and the structural member are jaws which retain the sleeve within the hole while the nut is turned.

Abstract: A collet surface structure is provided for a high-speed hydraulic press having collet interlock in order to eliminate leakage of oil into the clamping region. Furthermore, the formation of a harmful hydrostatic film thickness from the lubricating-oil film between the pressure rods and the collets is prevented, since the oil is immediately forced away due to the high clamping pressure between the clamping faces. These high clamping pressures result from the extremely short space of the lubricating-oil elimination grooves and the large capacity of the grooves. Thus, the oil-eliminating grooves are made large enough to eliminate reliably a hydrostatic oil film of at least 0.1 mm. This regularity is independent of the clamping diameter of the collet.
