[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. For example, metal parts such as spiral bevel gears can be processed and produced using powder metallurgy. Spiral bevel gears are a type of gear used for transmission between intersecting shafts. They have a conical tooth surface and usually transmit power between two staggered shafts. When producing spiral bevel gears using powder metallurgy, the workpiece needs to be stamped to shape and deform the workpiece, and the workpiece is processed to produce the required parts.

[0003] Therefore, a powder metallurgy spiral bevel gear stamping device is needed. The existing stamping die is not convenient to limit the movement range of waste chips, and the waste chips are easy to collapse onto the operator, causing harm to the operator.

The structure drives the movement of the protective frame through the cooperation of the first rack, the transmission gear and the second rack, so that the protective frame can cover the surface of the lower die. The protective frame can block the flying waste generated during the stamping process, limit the movement range of the waste, reduce the possibility of flying waste contacting the operator, and thus reduce the possibility of waste causing harm to the operator.

[0005] However, the above device may encounter the following problems during use: the structure places the workpiece on the lower die surface for stamping, but does not clamp and position the workpiece, causing the workpiece to shift when it is squeezed, and it is not convenient to position the stamping block, thereby reducing the stamping efficiency of the device.
