Production method of shaft sleeve with boss

Abstract

The invention provides a production method of a shaft sleeve with a boss, which comprises the following steps of: S1, adopting a forming process to obtain the shaft sleeve; s2, sintering the shaft sleeve by adopting a sintering process; s3, shaping the surface of the shaft sleeve by adopting a shaping process; in the forming process, the surface of the obtained shaft sleeve is smooth and free of bosses; and in the shaping process, the surface of the boss is finished by adopting a mold, and the shaft sleeve with the boss structure on the surface is obtained and is the shaft sleeve with the boss. Compared with the prior art, the shaft sleeve with the smooth surface and no boss is produced in the forming process, the manual positioning process is avoided in the sintering process and the shaping process, and therefore an automatic production line can be adopted for machining, potential safety hazards of operators are eliminated, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a production method of a shaft sleeve, in particular to a production method of a shaft sleeve with a boss, and belongs to the field of powder metallurgy. Background technique [0002] In the traditional powder metallurgy process, it needs to go through forming, sintering, and shaping processes in sequence. For special structures, in order to ensure a good effect of the shaping process, it is necessary to position the metal product during the shaping process. As the shaft sleeve with boss is too small, the conventional process forms the rough blank of the boss in the forming process, and then sinters and shapes it. During the shaping process, the position of the boss of the product needs to be positioned, but because the shaft sleeve itself is too small, The conventional method is used to position the product and the plastic mold, and the finishing process can only be carried out by manually holding and loading the material, res...

Problems solved by technology

As the shaft sleeve with boss is too small, the conventional process forms the rough blank of the boss in the forming process, and then sinters and shapes it. During the shaping process, the position of the boss of the product needs to be positioned, but because the shaft sleeve itself is too small, The conventional method is used to position the product and the plastic mold, and the finishing process can only be carried out by manually holding and loading the material, resulting in low production efficiency and safety production risks;
