摘要: The present invention discloses a special hydraulic press for bulging pressing forming of an automobile axle housing and a pressing forming method. A hydraulic press body is a closed frame consisting of an upper cross beam, a lower cross beam, four stand columns I, II, III, and IV, four vertical pull rods I, II, III, and IV, and four transverse pull rods I, II, III, and IV, and is used for balancing a deformation force up to 3000 T in the vertical direction or the horizontal direction in the pressing forming process. During pressing forming, the downward speeds of a main hydraulic cylinder, small left and right vertical hydraulic cylinders are precisely controlled to prevent the left end, the right end and the middle of the tube blank from bending.

摘要: A hydraulic forging press machine and a control method, whereby surging of the forging load or dead zones where the forging speed goes to zero is suppressed, and forging is performed with high precision throughout a wider range than the prior art, from low to high load. Pressure cylinders have a main pressure cylinder configured so working fluid is supplied during forging, and secondary pressure cylinders are configured so supplying and stopping of the supply of working fluid thereto are switched in response to the forging load, head-side hydraulic chambers of the secondary pressure cylinders being connected to a head-side hydraulic chamber of the main pressure cylinder via electromagnetic switching valves. Only the main pressure cylinder is used until the forging load exceeds a set load, and the number of secondary pressure cylinders used is sequentially increased as the forging load increases after the forging load exceeds the set load.

摘要: A press including a passive load leveler for bonding integrated circuit wafers, chips or substrates. The press includes a press frame, a press ram moveable relative to the frame, a first platen coupled to the press ram, and a second platen coupled to the press frame. The load leveler is coupled between the press frame and the second platen, and includes a main body having a first surface coupled to the press frame a plurality of pistons extending from the main body through a second surface and being in contact with the second platen. Each of the pistons is positioned within a piston chamber that is in fluid communication with a network of channels within the main body, where the pistons move relative to each other through a working fluid within the channels so as to maintain the first and second platens parallel to each other under the ram pressure.

摘要: The invention relates to a cycle press, in particular a short-cycle press, for producing and/or coating board-shaped materials, in particular engineered wood boards, comprising a press body having several press frames arranged next to one another in the longitudinal press direction, and further comprising an upper press plate and a lower press plate, wherein pressing cylinders supported on the press frames act on the upper press plate or the lower press plate. According to the invention, said cycle press is characterized in that the pressing cylinders are attached to the press frames by means of frame pins, wherein said frame pins engage in cut-outs of the press frames. Thus, the pressing cylinders can be prestressed against the press frames.
