Technical Field

[0001] The utility model relates to the technical field of powder metallurgy, in particular to a powder metallurgy stamping forming machine. Background Art

[0002] Powder metallurgy is a process for producing metal powder or using metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and then forming and sintering it to manufacture metal materials, composite materials and various types of products. The stamping equipment used in powder metallurgy is used to stamp the initially formed powder parts to completely shape them into the required size to facilitate subsequent sintering.

[0003] A Chinese utility model patent with announcement number CN221231585U discloses a stamping equipment for powder metallurgy. By setting a limit plate, a limit hole, an annular tube, a guide tube, a nozzle, a fixed column, an air pipe, a blower, a lower template, a cleaning hole, a lower mold and a filter plate, multiple parts can be stamped at the same time to improve production efficiency.

During this process, the lifting gear plate rotates with the transmission gear, so that the bevel gear A rotates with the bevel gear B, and then the push plate is deflected toward the two guide rails. When the height of the placement plate is at the same level as the through slot, the push plate just abuts the surface of the product. As the electric push rod B continues to rise, the push plate pushes the product on the placement plate onto the collecting component. After the electric push rod B rises to the highest point, it returns to its initial state, so that the push plate also returns to its initial state. After the stamping is completed, the product can be automatically discharged, thereby improving the working efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The stamping assembly is used to stamp metal powder. The stamping assembly includes two support rods fixedly connected to the top of the workbench 1 and a U-shaped frame 9 fixedly connected to the bottom of the workbench 1. The top of the support rod is fixedly connected to a top plate 10. The top of the top plate 10 is installed with an electric push rod A11. The bottom of the electric push rod A11 is fixedly connected to a pressure plate 12. The pressure plate 12 is sleeved on the outside of the support rod. The bottom of the pressure plate 12 is fixedly connected to a template 13. The top of the U-shaped frame 9 is fixedly connected to an electric push rod B14. A through slot is provided inside the workbench 1. The top of the electric push rod B14 is fixedly connected to a placement plate 15 that is slidably arranged inside the through slot. The outer side of the output end of the electric push rod B14 is sleeved with a lifting plate 16. The top of the lifting plate 16 is fixedly connected to two lifting gear plates 17.
