Power fixture forging is an important part in power system, its quality and performance directly affect the safety and stability of power system operation. Therefore, it is of great significance to study the material selection and quality control of electric power tool forgings for improving product quality and production efficiency. This paper will introduce and analyze the material selection and quality control of power fittings forgings.
Types and characteristics of materials
The raw materials of power fittings forgings mainly include carbon steel, alloy steel, stainless steel and so on. These materials have different chemical composition, mechanical properties and corrosion resistance characteristics, so the selection needs to be considered according to the use of the product environment and requirements.
(1) Carbon steel: carbon steel is an iron-carbon alloy with a carbon content of less than 2%, which has good machinability and weldability and low cost. However, its strength and wear resistance are low, and it is suitable for the general requirements of electric power goldware forgings.
(2) Alloy steel: alloy steel is a steel formed by adding one or more alloying elements on the basis of carbon steel, with higher strength and wear resistance, suitable for high strength and wear resistance requirements of power goldware forgings.
(3) Stainless steel: Stainless steel is a kind of steel containing chromium, nickel and other elements, with good corrosion resistance and oxidation resistance, suitable for working in a corrosive environment of power forgings.
Material selection scheme
When choosing the raw materials for power fittings forgings, the following aspects need to be considered:
(1) Chemical composition: The chemical composition of raw materials directly affects the mechanical properties and corrosion resistance of the product, so it is necessary to choose according to the use environment and requirements of the product.
(2) Mechanical properties: The mechanical properties of raw materials are one of the important factors affecting product quality, and need to be selected according to the force situation and working environment of the product.
(3) Cost: The cost of raw materials directly affects the production cost and market competitiveness of the product, so it is necessary to choose cost-effective materials under the premise of ensuring product quality.
Considering the above factors, it is of great significance to select the appropriate raw materials to improve the quality and performance of the power metal forgings.
Quality control of electric power fittings forgings
An important part of the production process
In the production process of electric power fittings forgings, the following links are prone to problems, and special attention is needed:
(1) Raw material inspection: the quality of raw materials directly affects the quality of products, so it is necessary to carry out strict inspection and control of raw materials.
(2) Forging process: forging process is one of the important factors affecting product quality, it is necessary to choose the right forging process and equipment to ensure the quality and performance of the product.
(3) Heat treatment process: heat treatment process is one of the important factors affecting the mechanical properties and corrosion resistance of the product, it is necessary to choose the appropriate heat treatment process and parameters to ensure the quality and performance of the product.
(4) Inspection and testing: Before the product leaves the factory, it is necessary to carry out final inspection and testing to ensure that the quality and performance of the product meet the relevant standards and requirements.
Quality control methods and means
In order to ensure the quality and performance of power fittings forgings, the following quality control methods and means need to be taken:
(1) Strengthen raw material inspection: strict inspection and control of raw materials to ensure that the quality and performance of raw materials meet the requirements. It can be inspected by chemical composition analysis, mechanical property testing, non-destructive testing and other methods.
(2) Optimize the forging process: according to the requirements of the product and the nature of the material, choose the appropriate forging process and equipment to ensure the quality and performance of the product. It can be optimized by simulation, process test and other methods.
(3) Strict heat treatment process: according to the requirements of the product and the nature of the material, choose the appropriate heat treatment process and parameters to ensure the quality and performance of the product. It can be monitored by hardness testing, metallographic structure observation and other methods.
(4) Strengthen final inspection and testing: Before the product leaves the factory, the final inspection and testing are carried out to ensure that the quality and performance of the product meet the relevant standards and requirements. It can be tested by mechanical properties testing, non-destructive testing, corrosion resistance testing and other methods.
Power fixture forging is an important part in power system, its quality and performance directly affect the safety and stability of power system operation. This paper introduces and analyzes the material selection and quality control from two aspects, and emphasizes the importance of material selection and quality control. In order to improve the quality and performance of power fittings forgings, it is necessary to strictly control the quality of raw materials, select appropriate steel and forging process, optimize forging and heat treatment process, and strengthen final inspection and testing. Only in this way can high-quality and high-performance power fittings be produced to contribute to the operational safety and stability of the power system.
