摘要： In a forming process with a press having in a frame a ram closing through the force of a cylinder with a moveable piston against a press table in a straight-line movement, the piston initially acts upon at least one knuckle joint system during the closing of the press, and a hydraulic cushion of the ram concludes the closing process with extension of the knuckle joint system in movement direction of the piston and straight-line support thereof against the frame. In a press having in a frame a ram closing through the force of a cylinder with a moveable piston against a press table in a straight-line movement, the ram is connected so as to be fixed with respect to the frame via at least two identically constructed knuckle joint systems, and the ram has a hydraulic cushion.

摘要： A hydroforming method for metal produces hardware having a throat in only one side and having approximately right-angled corners without causing thinning and breakage. The method includes using a working fluid to exert a liquid pressure on a metal embryo and cooperating with a push rod of a hydroforming mold to supply material from the lower edge, forcing the side sheet metals to bulge. Furthermore, by using the hydroforming mold to provide a downwardly pressing active force on the metal embryo, under feeding of the downwardly pressing active force cooperating with continuous liquid pressure, the metal embryo deforms and bulges such that each corner of the metal embryo and the wall corners of the die cavity of the hydroforming mold have approximately the same angles. Hardware, every angle of which approximates a right angle, can be obtained after removing the hydroforming mold. This method can also be used to obtain a metal box.

摘要： An end plunger for end feeding during a hydroforming process (such as tube hydroforming) has at least one releasable seal. The effect of the releasable seal is that it avoids pressurizing the blank in a nip area, thereby reducing friction and wear, and allowing increased end feeding with a given end feeding force. The releasable seal may be actuable, for sealing or releasing. The plunger may be modular or monolithic. A kit and method may incorporate the end plunger.
