模具出现变形的几个情况?

来源:http://www.jnhjgs.cn     发布时间:2020-11-20 14:29:32    点击:

在加工模具、加工零件时出现变形是很头痛的事情,并且也不能完全避免,加工过程中一旦某个模具或是零部件出现变形的情况就会产生损失,并且还会引发安全问题,使得零件或是模具出现变形的情况有几个呢?
Deformation is a headache in the process of processing molds and parts, and it can not be avoided completely. Once a certain mold or part deforms in the process of processing, it will cause loss, and it will also cause safety problems. How many cases can parts or molds deform?
1、内力改变了零件的加工精度,在加工过程中,零件被车床的三个爪子锁住,使零件在加工过程中受力稳定,随着时间的推移,会使车床夹头松动,使零件受力减小,产生变形。
1. The internal force changes the machining accuracy of parts. In the process of processing, the parts are locked by the three claws of the lathe, so that the force of the parts is stable in the process of processing. With the passage of time, the chuck of the lathe will become loose, and the stress of the parts will be reduced, resulting in deformation.
2、热处理容易变形,当处理一批薄和小的器件,通常首先进行热处理,然后,如果由于技术人员的知识是不固,不能很好地理解的结构和这些部件的性质,很容易使零件弯曲现象。
2. Heat treatment is easy to deform. When a batch of thin and small devices are treated, heat treatment is usually carried out first. Then, if the technical personnel's knowledge is not solid and they can not understand the structure and the properties of these parts, it is easy to make parts bend.

3、外力影响作用从而导致的零件加工过程中出现弹性变形,在进行分析零件加工时,会常常需要用到车床和夹具,当两者不平整时,会出现在企业固定零件时受力不均匀,那受力小的一方会产生不同变形。
3. Due to the influence of external force, elastic deformation occurs in the process of parts processing. When analyzing the processing of parts, lathes and fixtures are often needed. When the two are uneven, the uneven force will appear when the enterprise fixes the parts, and the side with small force will produce different deformation.
改进措施:
Improvement measures:
1、热处理和自然的一部分变形,然后用切割工具进行修整,保持部件的完整性。
1. Heat treatment and natural part of the deformation, and then use cutting tools to trim, maintain the integrity of the parts.
2、进行信息技术不断改进,增加零件刚度。
2. Information technology is continuously improved to increase the rigidity of parts.
