摘要： A high energy rate counterblow forming machine having opposing independently movable coaxial rams movable within pressure chambers containing a compressible working fluid for impelling the rams toward one another at high velocity from retracted cocked positions, through working strokes, into forming impact with work parts held in a bolster located between the rams. Operatively connected to the rams are power activated ram retractor means for retracting the rams to cocked position and thereby compressing the ram working fluid. The rams are held in their cocked positions by latches which are releasable in unison to release the rams for movement in unison through their working strokes to form the work parts without unbalanced impact loads on the machine. One described forming machine is adjustable to accommodate work parts of widely varying sizes.

摘要： A double-acting press with hydraulic coupling of upper and lower rams has an upper ram connected with a pair of pistons that extend into a closed oil-filled vessel. At least one other piston extends from this vessel up against a lower ram so that descent of the upper ram causes lifting of the lower ram. The piston rods of these pistons can all be inclined to the displacement axis of the rams to twist these rams into engagement with opposite guides and ensure their engagement in a fixed orientation of the forming surfaces. Two pistons can act upon the lower ram in which case the torque can be produced by using pistons of greater effective surface area to one side of the rams. Alternatively a pair of vessels can be provided, one to each side with a respective pair of pistons, and a pump can be provided to maintain the pressure in one vessel above that in the other. The guides can be two pairs of guides for each ram, one pair being above and laterally offset from the other.

摘要： A high-speed hammer wherein the working tools secured, respectively, on the anvil block and crosshead of a frame perform a working stroke being acted upon by a power unit mounted on the frame, and are returned to the initial position by compressed gas contained in a space in the anvil block. Said space accommodates a piston whose rod is adjustably connected with a bed for adjusting the position of the frame relative to said bed.

摘要： A hydraulic counter-blow hammer having a hydraulic coupling system for making the tups move in opposite directions and a hydraulic retraction system for retracting the tups prior to a stroke. The hydraulic retraction system is combined with the hydraulic retraction system without there being hydraulic intercommunication between the two systems. Differential pistons are connected to the upper tup and the differential pistons have two working faces moving in two different but co-axial cylinders. One cylinder is in the hydraulic coupling system for coupling the lower tup to the upper tup and the other cylinder is in the hydraulic retraction system for retracting the upper tup.
