Description

Technical Field

[0001] The present invention belongs to the technical field of gear sintering, and particularly relates to a powder metallurgy gear sintering device. Background Art

[0002] Powder metallurgy is a metal material preparation technology. By mixing metal or alloy raw material powders in a certain proportion, pressing them into shape, and going through process steps such as sintering or heat treatment, metal products with certain shapes and properties are prepared. The main steps of powder metallurgy include powder preparation, powder mixing, shaping, and sintering. Powder metallurgy gears are gears manufactured and shaped using powder metallurgy technology. The powder metallurgy sintering device for automotive gears is an important technical equipment. The powder metallurgy process usually requires filling metal powder into a mold, then using stamping equipment to press the metal powder in the mold into shape, and finally sintering the shaped gear in a high-temperature furnace. During the sintering process, a series of physical and chemical processes such as diffusion, recrystallization, fusion welding, chemical combination, and dissolution occur between powder particles to become a metallurgical product with a certain porosity. And when sintering powder metallurgy automotive gears, a copper infiltration process is usually required, that is, placing a copper ring on the gear and sintering them together. During the sintering process, the copper ring melts and the copper penetrates into the gear to increase the strength of the gear.

[0003] Currently, when sintering powder metallurgy automotive gears in the prior art, in order to increase the gear strength, a method of placing a copper ring on the gear and sintering them together is used for copper infiltration. However, usually, the copper ring is manually placed, and it is not easy for the copper ring to be concentric with the gear and it will be skewed, which easily affects the sintering efficiency and sintering effect. Therefore, it does not meet the existing requirements, and for this reason, we propose a powder metallurgy gear sintering device. Summary of the Invention
