Why: Roller struts and bearing seats are extruded?

Why: Roller struts and bearing seats are extruded ?

Option 3: Using composite die stamping, 1 , punching, blanking; 2 , bending, flanging, bulging; 3 , deburring;

By comparison with the reversing roller, the solution of the idler roller bracket stamping support is too low, and the stamping processing efficiency is not fully utilized. It is not suitable for high-volume production of parts; the second type of mold has a complex structure and only depends on the mold. And the ordinary equipment is very difficult to achieve, the production cost is relatively high; the third scheme mold structure is simple, easy to manufacture, but also can better guarantee the workpiece quality and accuracy. Roller fittings stamping bracket in the mold design process, a reasonable determination of the stamping process is the key. The stamping process affects product quality, production efficiency, mold structure complexity, and many other aspects. According to the stamping bracket part structure,   Drive roller size, tolerances and technical requirements, drive roller summarizes the following stamping molding process scheme for the roller bracket stamping bracket:

Scenario one: single-step die stamping molding, 1 , blanking; 2 , bending; 3 , flanged; 4 , bulging; 5 , punching; 6 , grooving; 7 , deburring;

　　  Roller program two: the use of progressive die punching, ( ) 1 , punching, bending, flanging, bulging, blanking; 2 , deburring;
