Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy, in particular to a shaping die for a powder metallurgy gear. Background Art

[0002] Powder metallurgy materials have the characteristics of flexible composition design adjustment, low production cost and excellent comprehensive mechanical properties. They are widely used in engineering machinery, transportation and other fields. The development of modern industry has more stringent requirements on the service conditions of mechanical parts, and also puts forward higher requirements on the performance and precision of parts. Therefore, the products after pressing and sintering must be shaped to meet the use requirements.

[0003] However, in order to increase the lubrication effect, the existing shaping mold first immerses the product in shaping oil before shaping, and then performs shaping. The shaping oil will accumulate inside the lower stamping cover. Since the shaping oil contains a lot of hydrogen, the material will suffer from hydrogen embrittlement, thereby affecting the life of the mold. Therefore, a powder metallurgy gear shaping mold is needed. Summary of the invention

[0004] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a powder metallurgy gear shaping die, which is used to solve the problem that in order to increase the lubrication effect, the existing shaping die first immerses the product in shaping oil before shaping, and then performs shaping. The shaping oil will accumulate more inside the lower stamping cover. Since the shaping oil contains more hydrogen, the material will produce hydrogen embrittlement, thereby affecting the life of the mold.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A shaping die for a powder metallurgy gear, comprising a workbench, support rods are installed on both sides of the top surface of the workbench, a cover plate is installed on the top surface of the support rod, a shaping cylinder is installed on the top surface of the cover plate, the output end of the shaping cylinder passes through the cover plate and is connected to a lifting plate, an upper die is installed on the bottom surface of the lifting plate, and a pressure plate is installed on the top surface of the workbench;

[0007] A lower mold is installed on the top surface of the pressure plate, a groove is opened on the top surface of the pressure plate, a card slot is opened on the inner side of the lower mold, a cleaning cylinder is installed on the inner side of the card slot, a card block is installed on the inner side of the cleaning cylinder, and a cleaning tool is installed on the bottom surface of the card block, thereby cleaning residual shaping oil to avoid affecting the life of the mold.

[0008] Furthermore, a sliding rod is connected between the lifting plate and the cover plate, thereby ensuring the stability of the lifting plate during the lifting process.

[0009] Furthermore, positioning rods are evenly installed on the bottom surface of the lifting plate, and corresponding positioning holes are opened on the top surface of the pressure plate, thereby ensuring accuracy during the shaping process.

[0010] Furthermore, a collecting chamber is installed on the top surface of the pressure plate, and the collecting chamber is connected to the groove, thereby facilitating the subsequent unified treatment of the remaining shaping oil.

[0011] Furthermore, a support frame is installed on the bottom surface of the workbench, and a buffer pad is installed on the bottom surface of the support frame, thereby reducing the impact of external factors on the equipment and providing a stable environment for the operation of the equipment.
