Analysis of the conditions that the stamping materials of precision stamping parts should have

Precision stamping parts are manufactured through a series of stamping processes such as stamping, extrusion, rolling, welding, cutting, etc., which are difficult to manufacture. In order to meet production requirements and achieve good product forming results, for precision stamping parts The stamping materials have higher requirements. So what conditions should the stamping material of precision stamping parts have? The following editor will analyze and answer it for you.

1. Stamping properties required for stamping materials of precision stamping parts:

1. Stamping materials should be easy to obtain high-quality and high-precision precision stamping parts, which is convenient for production and processing.

2. The limit deformation degree and total limit deformation degree of one stamping process of stamping material should be large enough to improve production efficiency.

3. The loss and wear of stamping materials to precision stamping parts and precision stamping dies are low, and it is not easy to produce waste products, which is convenient to increase production.

Second, the process requirements that the stamping material of precision stamping parts should meet:

1. The thickness tolerance of the stamping material should meet the national standard: different die gaps are suitable for materials of different thicknesses. If the thickness tolerance of the material is too large, it will not only directly affect the quality of the stamping parts, but may also cause damage to the die or press.

2. The stamping material has a high surface quality: the surface of the stamping material is clean and flat, free from defects such as oxide skin, cracks, rust spots, scratches, and delamination. The material with good surface condition is not easy to be broken during processing, and it is not easy to scratch the mold, and the surface quality of the obtained stamping part is also good.

3. Stamping materials should have good plasticity: stamping materials should have high elongation and section shrinkage, low yield and high tensile strength, high plasticity, and large degree of deformation, which is beneficial to The stability of the stamping process and the uniformity of deformation improve the dimensional accuracy of precision stamping parts.

4. Stamping materials should have good adaptability to mechanical joining and continued processing (such as welding, polishing and other processes), and should not damage mechanical equipment.

The stamping material of precision stamping parts is related to the performance and quality of the stamping parts. The selection of stamping materials needs to meet the above relevant conditions and meet the production requirements.
