What are the common problems in sheet metal stamping processing?

Sheet metal processing parts have the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. Widely used in electronic appliances, communications, automotive industry, medical equipment and other fields. With the increasing application of sheet metal parts, the design of sheet metal parts has become a very important part of the product development process. Mechanical engineers need to understand the design skills of sheet metal parts, so that the designed sheet metal parts can not only meet the requirements of product function and appearance, but also make the manufacture of stamping dies simple and low cost.

1. Common problems of stamping parts processing in sheet metal processing

1. Burrs: In the process of stamping or chamfering, the excess material is not completely left, and burrs appear under the section of the steel plate. According to the interface, when the burr height is greater than 0.2mm, the iron powder will damage the mold, causing convex and concave.

2. Unevenness: The surface of the material is abnormally convex and concave, which is caused by the uncoiled line. This is due to foreign objects (iron filings and dust) in 3.

3, caused by mixing. Roll marks: Caused by foreign matter adhering to the cleaning roller or feed roller (fixed spacing). Generally speaking, foreign objects printed on paper can be cleaned.

4. Scratches: Due to the rollers. Scratches may appear when the roller suddenly stops or accelerates.

5. Rolling may cause wrinkling at the edges: the guide rollers on the uncoiler line may cause wrinkling due to the small gap between the guide rollers on the die, which is caused by the unbalanced feeding of the rollers.

6. Scratches: The main reason for parts being scratched is that there are sharp scars on the mold or metal dust falls into the mold. Precautions are sanding mold marks and cleaning metal dust.

7. Bottom crack: The main reason for the bottom crack of the part is the poor plasticity of the material or the pressure of the die blank holder is too tight. The preventive measure is to replace the plastic material or loosen the edge holder.

8. Wrinkling of the side wall: The main reason for the wrinkling of the side wall of the part is that the material thickness is not enough when the upper and lower molds are installed (if it is relatively small, the thickness is allowed to be thinner) or deviation. This results in a larger gap on one side and a smaller gap on the other. The caveat is to immediately replace the material and readjust the mold.
