High strength and high precision metal tool forgings have a wide range of applications in industrial fields, such as automobile manufacturing, machining, engineering construction and so on. However, due to the characteristics of high strength and high precision, there are many technical problems in the production process. This paper will focus on the production of high strength and high precision metal tools forgings technical problems and solutions to discuss.
Technical problem
Fatigue and toughness of metallic materials
High strength and precision metal tools forgings usually need to use high strength metal materials, such as alloy steel, stainless steel and so on. These materials are prone to fatigue at high temperatures, reducing their service life. At the same time, it is also necessary to pay attention to the toughness of the metal during the forging process to ensure that the forgings have good processability.
Forging accuracy and processing difficulty
High strength and high precision metal tool forgings require very high dimensional accuracy and surface quality, which brings great challenges to the production process. In addition, the shape and structure of the forging will also affect its processing difficulty, such as deep holes, narrow slots and other parts may be difficult to process in place.
Heat treatment process and surface treatment process
Heat treatment process is a key step to improve the strength and hardness of metal materials, but it is also easy to cause deformation and cracking of materials during heat treatment. In addition, the choice of surface treatment process will also affect the service performance and life of the forging.

Selection and evaluation of raw materials
In view of the fatigue and toughness of metal materials, metal materials with high strength, good toughness and high temperature resistance should be selected. After selecting the right raw materials, it is also necessary to carry out a rigorous evaluation to ensure that it meets the production requirements.
Optimization of forging process and temperature control
In order to improve the accuracy and difficulty of forging, the forging process should be optimized and the processing temperature should be strictly controlled. Precision forging technology can be used, such as high-speed hammer forging, special press forging, etc., to improve the dimensional accuracy of the forging and reduce the surface roughness. At the same time, the forging temperature range is controlled reasonably to avoid fatigue and cracking of materials.
Application of digital forging and intelligent manufacturing technology
Digital forging technology can use computer-aided design, numerical simulation and other means to achieve accurate control of forging process. Intelligent manufacturing technology can improve production efficiency and reduce production costs through the introduction of automation equipment, robots and other means. The application of digital forging and intelligent manufacturing technology can effectively solve the technical problems in the production process of high-strength and high-precision metal tool forging.
