The planning and design of a stamping process is a necessary basis for the production of stamped parts. Based on the analysis of stamping processes, several sets of stamping process plans can be developed. Then, according to the production batch and the existing production conditions of the stamping processing plant, through the induction, analysis, and comparison of various plans, a process plan with the best skill economy can be confirmed.

1. Based on the shape and scale of the stamped parts, begin to confirm the nature of the stamping process, such as punching, bending, deep drawing, bulging, hole expansion, etc;

2. Calculate the degree of deformation of each stamping forming method. If the degree of deformation exceeds the limit deformation degree, the number of stamping times for that process should be calculated;

3. Organize a reasonable stamping sequence based on the deformation characteristics and quality requirements of each process. Attention should be paid to ensuring that the deformation zone of each process is a weak zone. The already formed parts (including holes or shapes that have already been punched) must not participate in deformation in future processes. Multi angle curved parts should be bent outward first and then inward, and necessary auxiliary processes such as shaping, leveling, and heat treatment should be organized; On the premise of ensuring the accuracy of stamping parts, confirm the reasonable process combination method according to the production batch and blank positioning and discharge requirements;

5. Stamping processing plants need to design two or more process plans and compare them from various aspects such as quality, cost, production rate, mold grinding and maintenance, mold lifespan, and operational safety, in order to select the best process plan;

6. Start confirming the stamping equipment for each process.

It can be seen that stamping process planning cannot be carried out independently, which makes it appear systematic and complex. The stamping process plan is the combination and organization of various processes required for processing stamping parts. Its importance is well known. A good stamping process plan is the fundamental guarantee of product qualification and an important factor in the surplus of stamping processing plants.
