No matter what kind of material is used for the prototype, when it exceeds certain service conditions, the prototype may be deformed or cracked. What should we do if the prototype is deformed or cracked? Is there any way to remedy it? Next, Jinan Handboard Processing Factory will talk about the remedial measures for the deformation or crack of the handboard model. You can have a look at the contents to understand.
1. After the hand board is deformed, there is a certain residual stress in it. The stress shall be relieved before the fabrication of the handboard. Stress annealing and natural aging can be used to eliminate internal stress.
2. Most of the hot cracks in the hand board are caused by mechanical stress, which is caused by metal solidification. The solution is to improve the structure of the hand board so that it has less contact with the metal. Another method is to increase the thermal brittleness of metals by controlling the sulfur content of metals.
3. The cold crack of the hand board is the crack of the product at low temperature. This is caused by the deformation of the hand board, which often occurs in the place where the hand board is stretched. The cold crack is generally small, but this crack is irreversible and can only be redone. Cold cracks often occur when making large and thin hand boards. Similarly, the preventive measures are to reduce the internal stress and control the phosphorus content in the metal.
It can be seen that once the hand model is deformed and cracked, the remedial measures are very troublesome, and even some of the deformations and cracks can not be remedied, which are major defects of the hand model. Therefore, the deformation and cracks are mainly preventive measures to avoid deformation and cracks as much as possible.
