As an important component in power system, the quality and performance of power fixture forgings directly affect the safety and stability of power system. With the continuous development of science and technology, precision forging technology has become an important research direction in the field of electric tool forging. The purpose of this paper is to study the precision forging technology of electric power tool forgings, in order to improve product quality and production efficiency, reduce production cost, and provide reference for future research.
Precision forging technology is an advanced plastic processing technology, through the precise control of material deformation process and forging process parameters, can achieve high precision, high surface quality forging production. Compared with traditional forging technology, precision forging technology has the advantages of high material utilization rate, excellent product performance and high production efficiency. Precision forging technology can be used for blanking, pre-forging, final forging and other processes in the manufacturing process of electric tool forgings.
Material selection
It is necessary to have good electrical conductivity and mechanical properties for electric power fixture forgings. Therefore, in terms of material selection, materials such as alloy steel or copper alloy with excellent electrical conductivity and mechanical properties should be selected. At the same time, in order to ensure the quality and performance of the product, it is also necessary to carry out strict chemical composition and mechanical properties testing of the material.
Forging technology
(1) Cutting process: precision cutting or CNC cutting and other methods are used to accurately cut raw materials to ensure the accuracy of cutting size and shape.
(2) Pre-forging sequence: The use of precision forging equipment for pre-forging, so that the material is fully deformed and evenly distributed, in order to reduce the deformation resistance and material loss during the final forging.
(3) Final forging sequence: precision forging equipment is used for final forging, so that the material is accurately formed in the mold. In the final forging process, it is necessary to strictly control the forging temperature, deformation speed and die precision and other process parameters to ensure the quality and performance of the product.
(4) Heat treatment process: According to product requirements, the appropriate heat treatment process is used to treat the forgings to improve the mechanical properties and electrical conductivity of the products.
Mold design
Precision forging technology requires higher precision and wear resistance of die. In mold design, materials with high strength, high wear resistance and high thermal stability should be selected, such as high-speed steel, cemented carbide, etc. At the same time, in order to improve the life of the mold and reduce production costs, coating technology and heat treatment technology can also be used to perform surface treatment on the mold.
The dimensional accuracy and surface quality of electric power tool forgings produced by precision forging technology have been significantly improved. By testing the mechanical properties and electrical conductivity of the product, it is found that the power metal forgings produced by precision forging technology have better mechanical properties and electrical conductivity. In addition, because precision forging technology can reduce material loss and improve production efficiency, the use of this technology can reduce production costs and improve the competitiveness of enterprises.
In this paper, the precision forging technology of electric tool forgings is studied. By selecting suitable materials and strictly controlling the forging process parameters, the production of electric tool forgings with high precision and high surface quality is realized. The experimental results show that the precision forging technology has better mechanical properties and electrical conductivity, which can reduce the production cost and improve the competitiveness of enterprises. The future research direction can include optimizing die design and improving forging process, so as to further improve the quality and performance of electric tool forgings. At the same time, it is also possible to consider applying precision forging technology to the manufacturing of other power components to promote the development and progress of the power industry.
