In our production and application of bolts, the problem of bolt cracking and deformation often occurs, which makes our final products fail to meet the requirements of our expectations. Many company managers are worried about this problem. However, in the final analysis, this problem is generally caused by the following aspects. If you can treat the problem symptomatically, the problem will be solved

1. Material problems: fake and inferior raw materials are usually solid or too soft. If they are solid, the riveting machine can not be riveted, and if it is too soft, the bolts are easy to deform. Therefore, it is necessary to use raw materials with appropriate types and strength for all aluminum lantern rivets, so as to solve the difficulties from the root.

2. The problem of canoeing at the center of the half space, the difference of the center of the half space or the deviation of the center of the half space will cause the split immediately.

3. If the punching needle does not point to the bolt management center or the punching needle is damaged, the bolt will crack and deform.

In addition, if the length of the riveting machine is too long, the length of the riveting tool will not be too long after the length of the riveting machine is too long.

5. Whether the working pressure and speed of riveting are suitable. The size and speed of working pressure are immediate. The price of special-shaped rivets endangers the bending level of bolts.

6. The top of the bolt head is not cut flat, resulting in bolt deformation.
