Description

Technical Field

[0001] The utility model relates to a forming die, in particular to a forming die for a wheel-shaped gear powder metallurgy part, belonging to the technical field of powder metallurgy. Background Art

[0002] The sprocket powder metallurgy mold is a supporting equipment for the sprocket forming process. When the sprocket is manufactured, the outer surface needs to be drilled and prepared, and a mold is needed to perform the forming operation. With the continuous development of science and technology, people's requirements for the manufacturing process of sprocket powder metallurgy molds are getting higher and higher.

[0003] After searching, the patent with application number CN201420658121.0 discloses a roulette-shaped powder metallurgy part forming die. The number and length of the dies are reduced, the manufacturing process is reduced, the cost is reduced, the structure is simple, and the mold frame does not need to be very complicated to meet the density requirements. However, the existing powder metallurgy forming dies have certain defects in processing and production. During processing, they are often limited to a certain position of hydraulic pressure, and the mold type is single, and often only one model can be processed. Long-term hydraulic work lacks a buffer structure and is prone to damage to the hydraulic plate. Not only is the production efficiency low, but replacing the hydraulic mold will also waste a lot of time, affecting the processing speed. In addition, the existing processing devices often lack automatic feeding equipment, which can directly replenish the material after the hydraulic pressure is completed to improve the efficiency. Therefore, in response to the above problems, we propose an improved roulette-shaped gear powder metallurgy part forming die. Utility Model Content
