Automobile braking system piston cold extrusion cold forging blank
Product introduction:
Material 10#
Process: three position continuous forging (upsetting + reverse extrusion + finishing)
Heat treatment: None
Product application: automobile brake

 

Process introduction:
The cold forging process is applied to extrusion forming. The precision is high, the part size meets the requirement of the finished product directly, the blank turning allowance is small, and the mechanical strength is high. The annual output is 8 million pieces

 

Process characteristics:
In view of the characteristics of large quantity and fixed size of the piston, we have developed a fully automatic cold forging technology with three stage stepping drive without manual operation. Only the pre processed blanks are put into the material basket to be automatically fed, then upset, reversed packed and refined, and placed in the discharge basket. Full automatic technology, steady beat, and no artificial factors make the product very stable in large quantities.

Continuous technological innovation has promoted the development of cold extrusion technology. Since 80s, precision forging experts at home and abroad began to apply the shunting forging theory to the cold forging of Yu Zheng gear and helical gear. The main principle of distributary forging is to establish a material diverting cavity or distributary channel in the forming part of the blank or die. During the forging process, the material is filled with the cavity, while some of the material flow to the shunt cavity or the shunt channel. The application of the distributary forging technology makes the higher precision gear less and less cutting to achieve the industrialization scale rapidly. The literature for proposed, the slenderness ratio is 5 extrusions, such as piston pin usesaxial Yu liaokuai the method through the axial split cold extrusion forming a realization, and the stability of punch is very good; for the flat kind of spur gear forming, forming material block can also achieve the radial residual products cold extrusion.
