The control of dimensional accuracy of forged components of unusual shape is vitally important during the manufacturing process. In general, the dimensional accuracy can be controlled from three aspects:
- Pre-forging design and die production
The dimensional accuracy of forged components of unusual shape is affected by pre-forging design and die production. Therefore, in the forging process, dimensional accuracy should be set as a top priority, and comprehensive analysis and optimization of die design and production processes should be conducted to ensure that dimensional accuracy errors are minimized.
- Control of preheating temperature and forging temperature
Different materials have different properties under different temperatures, significant temperature changes may result in unstable dimensional accuracy of forged components of unusual shape. Therefore, in temperature control, it is necessary to ensure accurate control of preheating temperature and forging temperature. Meanwhile, measures should also be taken to reduce errors caused by temperature changes, such as using progressive preheating, slow cooling, and other ways to control temperature.
- Subsequent heat treatment
Dimensional accuracy errors can be corrected to some extent after forging, but if not processed correctly, it will seriously affect the dimensional accuracy of forged components of unusual shape. Therefore, in the subsequent heat treatment, it is necessary to carefully consider the effects of temperature and time control, as well as the control of internal stress release.
In conclusion, to ensure the stability and excellence of dimensional accuracy of forged components of unusual shape, it is necessary to comprehensively consider the above three aspects in the forging process, adhere to the principles of excellence, follow production standards and specifications, adopt the optimal forging process flow and a strict quality control system.
