What is the process of metal stamping parts?

Hardware stamping is a process of deforming or breaking stainless steel, iron, aluminum, copper and other plates and foreign bodies with punches and dies to reach a certain shape and size. Hardware stamping is an indispensable and important production process in hardware factory, with convenient operation, high production efficiency and easy realization of mechanization and automation. The following small series of Mingfengqing Hardware Products Factory will introduce the hardware stamping process for everyone.

1. Material preparation: Different products need different mold materials. Appropriate mold materials should be selected according to product characteristics, such as mold handle, upper cover plate and upper fixture, stripper plate, lower template, backing plate and bottom plate.

2. Rough machining: After selecting materials, the plane and side surface are preliminarily machined by milling machine. It is usually necessary to use male plywood, stripper, lower formwork and backing plate, bottom plate, upper cover plate and ejector plate.

3. Finishing: the plane and four corners need to be machined into right angles with a grinder. Grind the male plywood, stripper, lower formwork and backing plate at right angles, and then grind the bottom plate and upper cover plate.

4. Scribing: Put the finished, polished and right-angled template on the scribing table, scribe with a scribing height ruler according to the drawing of the mold, and finally dot, drill and tap the scribed template.

5. Heat treatment: high-temperature quenching, tempering, tempering and annealing are carried out on the plate that needs heat treatment to improve the hardness of the lower template and module, further finishing is carried out, the plate is polished into a plane and forms a right angle, and then wire cutting is carried out.

6. Assembly and die testing: choose the die frame or supporting guide post and guide sleeve to complete die assembly, install the assembled die on a punch for debugging and stamping, and finally measure the stamped die to confirm whether it meets the requirements of the product, thus completing the whole stamping process.
