Precision forging parts heat treatment process design basis

Precision forging parts heat treatment process design basis, mainly product parts drawings and their technical requirements, blank drawings and their technical requirements, technical standards related to process design, precision forging parts heat treatment before and after the sequence of heat treatment of precision forging parts heat treatment technology requirements, as well as the production site operator's technical level and the specific conditions of the equipment, and so on. Below, respectively, are the details of the specific content of these bases over the application.
1. Product parts drawings and their technical requirements
Product parts drawings should be approved by the provisions of the valid version of the procedure. Parts drawings, there should be clear technical requirements of the heat:
1) material grade (if necessary, need to provide the corresponding material standards).
2) precision forging parts heat treatment of the hardness value (if necessary, the proposed standard specimen of the same furnace treatment of other mechanical indicators).
3) For chemical precision forged parts heat treatment of parts, drawings should be marked on its chemical precision forged parts heat treatment parts and their size, penetration layer and its surface hardness, penetration layer organization, and relevant standards.
4) for precision forging parts heat treatment with special inspection requirements the parts, should be marked with their inspection categories and related standards.
2 parts blank drawings and their technical requirements
Parts blank drawings, and parts drawings are derived from the casting, forging, welding, or semi-finished parts drawings. Single-piece production when the blank drawing can generally be outlined in the parts drawing with a red and blue pen can be; mass production should be drawn separately blank drawings, and according to the prescribed procedures by the relevant process technical responsible person countersigned and audited before being used in production. The blank sample should have clear technical requirements:
1) material grade (if necessary, need to provide the corresponding material standards).
2) The hardness value of the blank and its test site and test method.
3) If necessary, should indicate the organizational status of the blank and the implementation of the relevant standards.
3 process technology standards
Process technology standards (including process design quality standards), are to improve the quality of process design work, and evaluation of the level of process design is an important basis. In recent years, different levels (national, industry, enterprise) of technology standards continue to improve and enhance the process design to provide a more reliable basis, greatly improving the level of technology design and design quality of enterprises. Engineers and technicians engaged in the design of the art, in the specific work should be conscientiously implemented, the implementation of technology standards, and constantly improve the level of technology standards, is conducive to further improve product quality.
