In the process of mechanical parts
processing, reasonable arrangement of the heat treatment process can make the cold and hot process cooperate better, avoid deformation due to heat treatment.
So you know how to reasonably arrange heat treatment process of position?
By small make up next to share!
1, prepare heat treatment prepare heat treatment goal is to eliminate internal stress generated in the manufacturing process, improve the machinability of metal materials, preparing for the final heat treatment.
Belongs to prepare heat treatment with conditioning, annealing, normalizing, etc. , before rough machining, general arrangement.
Arrange before rough machining, can improve the machining performance of materials;
Arrange after rough machining, is helpful to eliminate the residual internal stress.
2, in the end, generally should be arranged in rough machining, heat treatment and a half after finishing, before and after finishing.
Heat treatment deformation, such as carburizing and quenching, tempering, etc. , should be arranged before finishing, so that the correct heat treatment deformation when finishing;
Deformation smaller heat treatment, such as nitriding, after can be arranged in finish machining.
3, aging treatment of aging treatment aims to eliminate internal stress, reduce the workpiece deformation.
Aging treatment of natural aging, artificial aging and cold processing three categories.
After aging treatment is generally arranged in rough machining, finish machining before;
For higher accuracy requirement of precision machined parts can be in after arrange an aging treatment;
After cold treatment generally arranged in the tempering treatment or after finishing or process finally.
4, anti-corrosion surface treatment for surface or surface decoration, sometimes need plating on the surface or blue handle this surface treatment is usually arranged at the end of the process.
Is the production process from raw materials,
Or semi-finished products)
All the process made products.
For machines including transportation and storage of raw materials, production preparation, blank manufacturing, parts machining and heat treatment, product assembly and debugging, paint and packaging, etc.
Modern enterprise with the content of the production process is very extensive, the principle and method of system engineering organization and guide the production, the production process as a production systems with input and output.
Can make the enterprise scientific management, make the enterprise more resilience and competitiveness.
In the process of production, directly change the raw materials (
Shape, size and performance, and make it into a finished product, the process of the called process.
It is the main part of the production process.
For example, the blank casting, forging and welding;
Change the material performance of heat treatment;
Parts of machinery processing, etc. , all belong to the technological process.
The technological process is composed of one or several of order process.
Process is the basic component of unit process.
Process refers to the work in a place, to one or a set piece for completion of that part of the process.
Constitute the main characteristics of a process is not changing processing objects, equipment and operator, and the content of the process is completed in a row.
Above is mechanical parts processing and heat treatment process in the process of location arrangement, the hope can help to you!
