Abstract: A spinning forming method is a method of forming a formation target region of a plate into a tapered shape by using a processing tool while rotating the plate. The processing tool is moved from an inside edge of the formation target region to an outside edge of the formation target region while being pressed against the plate. The plate is rotated in a state where a position of the processing tool is fixed at the outside edge.

Abstract: A switching unit is capable of switching in a stepwise manner a relative position of a second die with respect to a cutting member in an approaching-and-separating direction. A restriction member abuts on the second die and restricts a position of the second die with respect to a movable body in the approaching-and-separating direction. A driving unit changes a position of the restriction member with respect to the second die, and switches an abutment state of the restriction member with respect to the second die. A level difference is formed on a surface on a side of the restriction member facing to the second die, and/or on a surface on a side of the second die facing to the restriction member.

Abstract: 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.
