In the whole process of machining, because of a variety of machining deviation or other production and processing personnel operating errors, it is very easy to cause steel deformation. There is no way to deal with this problem. First, it is important to understand the actual cause of the deformation and then use the release to solve it. Therefore, in the whole process of machining, it is very easy to cause the key elements of steel deformation.
Deformation caused by steel clamping
When there are many directions of clamping force effect on the steel parts, the sequence of clamping force shall be considered. For the clamping force that makes the steel parts touch the supporting point, it shall be effective first and not easy to be very large. For the key clamping force that balances the cutting speed, the stress effect shall be final.
Secondly, the total area of contact between steel parts and fixture should be expanded or the radial clamping force should be selected. It is a reasonable method to improve the rigidity of the parts to deal with the clamping deformation, but because of the appearance and structural characteristics of the thick wall parts, it has low rigidity. In this way, under the effect of clamping force, it will cause deformation.
The material and structure of steel parts will damage the deformation of steel parts
The size of the shape variable is directly proportional to the appearance complexity, the aspect ratio and the wall thickness size, and to the rigidity and reliability of the material. Therefore, in the design of parts, try to reduce the damage of this element to the deformation of steel parts.
Especially in the construction of large and medium-sized parts, reasonable configuration should be ensured. Before production and processing, the defects such as the strength and looseness of the hairy embryo should be strictly controlled to ensure the quality of the hairy embryo and reduce the deformation of the steel parts.
