Stamping forming of stainless steel forgings

Sheet forming skills are mainly composed of stamping die, sheet data and lubrication. Finding out the relationship between these components and applying them is the development direction of sheet forming skills. This direction is to discuss the molding function of the data, in order to make the stamping skills to reach a high speed, continuous and stable operation, and after collecting a variety of shape molding examples to discuss the difficulty of forming different shapes and scales. The forming process of stainless steel sheet and other metal sheet forming processes include stamping, bulging, flanging, reaming, local forming, spinning, spinning and roll cold forming and other forging fundamental forming processes. However, stamping forming is the fundamental cold forming method of stainless steel plate and strip forming. The forming of stainless steel forgings has the following characteristics compared with other metal forming:
(1) high strength;
(2)0high sensitivity to work hardening;
(3) Good wear resistance;
(4) the possibility of bonding is greater;
(5) low thermal conductivity.

All stainless steel forgings require more forming force than low-alloy steel and regular carbon steel of the same thickness. This is mainly because of their relatively high yield strength. In general, the force required by stainless steel forming is twice that of the general steel, and different stainless steel steel, forming the need for power has a great difference. Such as austenitic stainless steel because the work hardening speed is fast, not only need greater initial forming force, and in the forming process also need more forming force.

In the evaluation of stainless steel plate forming processing, generally is to conclude the forming function to mark. The INDUCTION MOLDING FUNCTION IS COMPOSED OF THE fracture RESISTANCE OF THE MARK BREAKING LIMIT (DEEP DRAWING FUNCTION, FLANGE FORMING FUNCTION, edge EXTENSION FUNCTION, BENDING FUNCTION), the WRINKLE resistance OF THE MARK FORMING mold and THE DATA, and the fixity of the fixed shape after THE mark forming is finished and the unloading is finished.
