Aug 14, 2018

Technical field

[01]The invention relates to a powder metallurgy formula and process of belt pulley, belonging to the technical field of powder metallurgy.

Background technology

[02] Powder metallurgy is a process of making metal materials, composites and various types of products by forming and sintering metal powder (or mixture of metal powder and non-metal powder) as raw materials.Because of the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays an important role in the development of new materials.However, most of the existing belt pulley is made of blank by cast iron process and then made by cutting. Defects such as pores, pinholes, slag inclusion, cracks and pits are often found in the processing process due to various factors.At the same time, cast iron parts have many machining angles, large waste, high cost, low product accuracy, need to be balanced treatment, tedious process procedures, low production efficiency.Although there are a few production processes using powder metallurgy, due to the limitations of its formulation and process, the formulation is not optimized enough, and the products of belt pulley have problems of hardness or softness, which leads to the brittleness, vibration, noise and short life of the belt pulley.The belt is easy to wear away the belt pulley due to too soft, and it is easy to deform when used for a long time.Therefore, there is an urgent need for an optimized formula and technology of powder metallurgy of belt pulley.
