In the parts processing industry, the most taboo problem is the deformation of parts, once it appears, the consequences will be unimaginable, one affects the economic efficiency of enterprises, the second to cause a series of safety problems, making the enterprise anxious. So what exactly is the cause of the problem of parts deformation? And how to do to improve it?
The main points are as follows.
1, the role of internal forces lead to parts processing accuracy change. Skilled workers know that during processing, the parts are tightened by the three jaws of the lathe to ensure that the parts are processed when the force is stable, over time, it will cause the lathe chuck to loosen, making the parts shrink in force, there will be deformation.
2, heat treatment processing is easy to produce deformation. In the processing of some thin and small parts, generally to first heat treatment, this time if the technical staff due to the professional knowledge is not solid, can not well understand the structural properties of these parts, it is easy to make the parts appear bending phenomenon.
3, the role of external forces resulting in parts processing elastic deformation. In the parts processing, will often use the lathe and fixture, when the two are not flat, will appear in the fixed parts when the force is not uniform, that the force is small side will produce deformation.
Improvement measures.
One, after the parts are heat-treated and naturally deformed, then trimmed with professional cutting tools to ensure the perfection of the parts.
Second, technical innovation to increase the stiffness of the part.
Technicians need to improve technology, increase innovation, choose the appropriate limit of heat treatment, change the stiffness of the parts, which makes the parts less likely to deformation.
