HOT PRESS FORMING DIE
20230321712 · 2023-10-12 ·

A hot press forming die includes a die main body (2) made of alloy tool steel, and a number of forming projections (3) projecting on the die main body and configured to form a forming surface (5) that comes into contact with a heated metal plate material that is an object to be formed and form a refrigerant passage through which a cooling medium flows. The die main body includes a first forming portion (14) in which the forming surface is formed to extend in a direction intersecting a forming direction of the metal plate material, a second forming portion (15) in which the forming surface is formed to extend in the forming direction, and a third forming portion (16) configured to connect the first forming portion and the second forming portion such that the forming surface becomes a convex surface. The forming projection provided on the third forming portion is formed to be a projecting strip extending between the first forming portion and the second forming portion.

It is possible to provide a hot press forming die for which forming convex portions with a high hardness can easily be formed.

Low melting temperature metal fill for additively manufactured tools

A forming tool including an additive manufactured polymer shell defining a first side and an opposite second side. The forming tool includes a support structure mechanically connected to the second side of the shell. The support structure may be formed by pouring a molten backfill material into the shell, and solidifying the backfill material. The backfill material includes a low melting temperature metal, fusible alloy, or other element. The solidified backfill material has a strength and rigidity greater than the polymer used to make the shell. The first surface of the shell includes a complex surface for bringing into contact with a material in a stamping process to form a stamped part.

20220274215 · 2022-09-01 ·

A system for use in repairing a stamping press die. The system includes an imaging system configured to perform a scan on a pressing surface of the stamping press die, wherein a profile of the pressing surface is determined based on the scan. A computing device is configured to compare the determined profile to a desired profile of the pressing surface, and to generate a repair template based on dimensional variations between the determined profile and the desired profile. A projection system is configured to display the repair template on the pressing surface.

Mold and method for manufacturing drawn can

A mold used for blanking a metal plate to shape a blank to be drawn. The mold has a surface treatment film and a top face to be brought into contact with the metal plate and a peripheral end face communicated indirectly with the top face. At least the top face is coated with the surface treatment film.
