Metal forgings are the key parts widely used in the industrial field, and their performance and quality have an important impact on the safety, stability and life of the entire mechanical equipment. Deformation and stress control is an important link in the production of metal forgings. In this paper, the principle and application of different deformation and stress control technologies will be deeply discussed to provide reference for the production of metal forgings.
Deformation control
In the production process of metal forgings, the control of deformation has an important impact on the quality and performance of the product. Excessive deformation may lead to cracks in metal materials and reduce mechanical properties, while too small deformation may lead to work hardening of metal materials and affect subsequent processing. Therefore, the deformation amount should be reasonably controlled according to the product requirements and material characteristics to ensure the quality and performance of the product.
Deformation prevention and correction
In the production process of metal forgings, the causes of deformation mainly include unreasonable process design, improper operation, equipment failure and so on. In order to prevent and correct deformation, it is necessary to start from many aspects such as process design, production process control and equipment maintenance. For example, optimizing process design to reduce unnecessary process steps; Strengthen production process control to ensure operation standards; Maintain the equipment regularly to ensure normal operation of the equipment.
Stress generation
Stress is a force inside the metal forgings, caused by material deformation, temperature change, chemical composition and other factors. The production of stress will affect the dimensional accuracy, surface quality and performance of the product, so the stress control is very important for the production of metal forgings.
Stress relief
Stress relief is an important part of stress control. Common stress relief methods include heat treatment, tempering, calibration, etc. Heat treatment is to change the structure of the metal by heating and cooling, so as to eliminate stress; Tempering is the tempering of metal materials at a certain temperature for a period of time to eliminate stress; Correction is the mechanical correction of the shape and size of the metal material to eliminate stress.
Stress prevention
Stress prevention is an important part of stress control. The prevention of stress mainly starts from two aspects: process design and production process control. In the process design, the mechanical properties, deformation, heating temperature and other factors should be considered to develop a reasonable process flow. In terms of production process control, various parameters in the production process should be strictly controlled, such as deformation speed, deformation amount, heating temperature, etc., to avoid the occurrence of excessive deformation and uneven heating.
The deformation and stress control technology of metal forgings is an important link in the production of metal forgings. Through reasonable deformation and stress control technology, the quality and performance of metal forgings can be effectively improved, and the production cost can be reduced. In the future, with the continuous development of science and technology, deformation and stress control technology will continue to improve and perfect, to provide more efficient, more stable and more reliable technical support for the production of metal forgings. At the same time, with the needs of industrial development, the deformation and stress control technology of metal forgings will also put forward higher requirements, which will be the direction of further research and exploration in the field of metal forgings production.
