There are many factors that lead to deformation of mechanical parts, for different reasons to take different measures to solve. In practice, we should pay attention to all the details of machining, and constantly improve the production process, and strive to reduce economic losses to a low level, in order to determine the stable work of mechanical equipment, to achieve the quality of machining is good, the rate is good goal, so as to promote the machining industry has a good prospect of development and the more broad market.

Mechanical parts processing deformation improvement measures

In the actual parts processing, there are many factors that lead to deformation of parts. In order to fundamentally solve these deformation problems, operators need to seriously explore these factors in the actual work, and combined with the essence of the work, the development of improvement measures.

1, increase the stiffness of the parts to prevent excessive deformation in mechanical parts processing, the stability of the parts can be affected by many objective factors. Is in the parts after heat treatment, due to the phenomenon of stress contraction, will lead to deformation of the parts. Therefore, in order to prevent the deformation phenomenon, technicians need to choose the appropriate heat-limiting treatment, and then to change the part stiffness. This requires the application of appropriate heat-limiting treatment measures in conjunction with the properties of the part, thereby determining stability. Even after heat treatment, there will be no significant deformation.

2, measures to reduce the clamping force in the processing of poor rigidity of the parts, the need to take some measures to increase the degree of rigidity of the parts, such as can increase the auxiliary support. It is also necessary to pay attention to the point of intensification and the contact area between the parts, according to the different parts, choose a different clamping method, such as the processing of thin-walled sets of parts, you can choose to have the elasticity of the shaft device for clamping, pay attention to the location of the intensification should be chosen to rigidity of the better part. For long shaft type mechanical parts, you can use both ends of the positioning method. For long diameter parts, the need to use both ends together with the clamping method, can not use "one end of the clamping, one end of the suspension" method. In addition, in the processing of cast iron parts, the design of the fixture needs to increase the rigidity of the cantilever as a principle. A new type of hydraulic clamping tool can also be used to prevent the parts in the process of machining due to clamping deformation caused by quality problems.
