摘要： Systems and methods of forming articles using electromagnetic radiation are disclosed. In some aspects, the system includes a plurality of forming modules movably mounted relative to an infeed mechanism. The infeed mechanism is configured to supply pre-form articles to the plurality of forming modules, and each of the plurality of forming modules includes a multi-segment mold disposed about an electromagnetic coil. The electromagnetic coil is configured to impart an electromagnetic force on the pre-form articles when supplied with electrical energy that urges the pre-form articles into contact with the multi-segment mold to produce the formed containers.

摘要： A process for forming a hollow member with A complicated cross-section wherein a section of a tube blank first undergoes a bending deformation due to its internal pressure and bend moment generated by the upsetting of an upper die, and is then compressed to be molded under the support of the internal pressure. The process of the invention does not require the reshaping step at an increased pressure. The process can make a hollow member with a complicated cross-section formed under a low pressure, and solves a technical bottleneck relating to a conventional process for forming this kind of members that is subject to an ultrahigh pressure generator.

摘要： Example methods and devices for producing a shaped component may involve positioning a workpiece having a hollow region and consisting at least partially of steel in a mold of a device. One or more docking punches may secure the workpiece within the mold and serve to introduce a pressurized fluid into the hollow region of the workpiece within the mold. The workpiece may be hot-formed in this process. The present disclosure concerns a variety of methods and devices that may be utilized to counteract a cooling of the workpiece in a region of the docking punch and reduce a temperature difference that may exist between the workpiece and the device.

摘要： A guide pin assembly for metal forming dies includes a cylindrical guide pin body with a tapered guide pin head to guide associated die members from converging and diverging positions. A base is used to secure the guide pin assembly to one of the die members in a reciprocating die. The base includes a tapered surface that coincides with the tapered surface of the guide pin head to transfer the directional force, caused by the diverging die members, on the guide pin assembly to other die components. The guide pin assembly includes additional dampening components between the guide pin assembly and the base to dampen the impact caused by the diverging die members.

摘要： A bulge forming method includes arranging a raw material tube inside a die having an inner surface shape, in which plural crest portions and root portions are alternately formed, and providing a rod inside the raw material tube in the axial direction of the raw material tube, and the rod has a pressurized liquid supply opening. The bulge forming method further includes providing a pair of sealing portions so as to have the pressurized liquid supply opening therebetween, and the sealing portions seal a space between the raw material tube and the rod. The bulge forming method further includes moving the rod in the axial direction while applying compressive stress to the raw material tube in the axial direction and supplying a pressurized liquid from the pressurized liquid supply opening into the raw material tube, whereby the raw material tube is formed into the shape of the inner surface of the die. The sealing portion is in an anterior side of a forming direction is applied with liquid pressure of the pressurized liquid in a direction from the rod toward the raw material tube so as to be followable to bulging of the raw material tube. The distance between the sealing portions is set to have a length of at least two crest portions of the inner surface shape of the die, and a length in the axial direction of the sealing portion in a posterior side of the forming direction is set to have a length of at least one crest portion of the inner surface shape of the die.
