摘要： An automotive component manufacturing method includes a molding process of pressing a portion of a hollow tube formed from a metal material, or a composite material including a metal and a resin, so as to deform the portion of the hollow tube, from a tube outer side toward a tube inner side, to beyond an axial center of the hollow tube, and mold the portion of the hollow tube into a deformed section deformed with a concave profile; and a deformation process of deforming a location having a high level of residual stress in a closed cross-section configured by the deformed section so as to deform the location out-of-plane.

摘要： The controller controls the gas supply of the gas supply unit so as to maintain a pressure in a metal pipe material at a first pressure when a gas is supplied into the metal pipe material which is formed into a pipe portion in a main cavity portion in a state where an upper die and a lower die are joined to each other. It is possible to prevent pressure drop in the pipe portion caused by cooling of the pipe portion due to a contact between the dies, and the pipe portion. Thus, it is possible to suppress a decrease in a force for pressing the pipe portion against the dies. It is possible to suppress a decrease in adhesion between the pipe portion and the dies when the metal pipe is formed, and it is possible to suppress occurrence of variations in hardenability in the pipe portion.

摘要： A forming device includes a gas supply part supplying a gas into a metal pipe material held and heated between a first die and a second die paired with each other. A driving mechanism moves at least one of the first die and the second die in a direction in which the dies are combined together. A first cavity part is formed between the first die and the second die to form the pipe part. A second cavity part communicates with the first cavity part to form the flange part. A flange forming member can be allowed to advance or retreat in the second cavity part, and forms the flange part. A controller controls the gas supply of the gas supply part, the driving of the driving mechanism, and the advance or retreat of the flange forming member.

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.

摘要： A hydroforming apparatus and working method able to simply find a load path are proposed, which system and method use a mold in which contact sensors able to judge contact with a metal tube inside the mold are mounted at least at two different positions in the tube axial direction, perform a first step of axially pushing tube ends in a state with the internal pressure held at a constant value and stopping the progress of the axial pushing action when judging that among the contact sensors not yet in contact mounted at positions closest to the tube ends detect contact with the metal tube, next perform a second step of raising only the internal pressure while leaving the positions of the tube ends fixed and stopping the increase in the internal pressure when the contact sensor not yet in contact judges contact, next perform a third step of lowering the internal pressure to the value before raising it while leaving the positions of the tube ends fixed, and repeat said first step to third step until all of said contact sensors judge contact so as to obtain a hydroformed part.
