Car tire bolt cold forging die design
[Abstract]：The traditional production of automobile tires bolt automatic cold heading machine and multi-station machine， their production accuracy needs to be improved，how to produce high-precision automotive tire bolts？Car tire bolt cold heading die is designed for the production of high precision automotive tire bolt. .The main topic of is the study of car tires bolt cold heading forming and mold design. By contrast to the molding program， choose the optimal program。From under the material， pre-treatment of raw materials，upsetting extrusion molding and so on design calculations of the relevant parameters to the size of the mold design.
