In the field of forging processing, the design and manufacturing technology of die is one of the key factors that determine the quality, production efficiency and cost of forging. As an important tool for forging forming, the design rationality and manufacturing accuracy of die directly affect the shape, dimensional accuracy and surface quality of forging. Therefore, this paper will deeply discuss the die design and manufacturing technology in forging processing.
Basic principles of mold design
Meet the design requirements of forging: Die design must first meet the design requirements of forging, including shape, size, accuracy and surface quality. Designers need to choose the appropriate mold type, structure and material according to the specific requirements of the forging.
Simplified mold structure: under the premise of meeting the design requirements of forgings, the mold structure should be simplified as far as possible to reduce the processing difficulty and manufacturing cost of the mold. At the same time, simplifying the mold structure also helps to improve the life and stability of the mold.
Ensure the strength and stiffness of the mold: the mold needs to withstand greater pressure and impact force in the forging process, so it is necessary to ensure that the mold has sufficient strength and stiffness. Designers need to reasonably design the mold cross-section shape, wall thickness and reinforcement structure according to the forging process and forging characteristics.
Consider the manufacturing process of the mold: the mold design should consider its manufacturing process, including processing, heat treatment, assembly and other process requirements. Designers need to choose the right material, design a reasonable processing allowance and develop a suitable heat treatment process.
The main steps of mold design
Forgings analysis: detailed analysis of forgings to understand their shape, size, accuracy and surface quality requirements, to provide a basis for mold design.
Mold type selection: According to the characteristics of forging and forging process requirements, choose the appropriate mold type, such as open mold, closed mold, combined mold, etc.
Mold structure design: According to forging requirements and mold type, design the overall structure of the mold, cross-section shape, wall thickness and reinforcement structure.
Mold material selection: According to the forging process and mold design requirements, choose the appropriate mold materials, such as carbon steel, alloy steel, hard alloy, etc.
Mold processing allowance design: According to the mold material and processing technology requirements, design a reasonable processing allowance to ensure the processing accuracy and surface quality of the mold.
Mold heat treatment process design: According to the mold material and forging process requirements, develop a suitable heat treatment process to improve the hardness and wear resistance of the mold.
Mold manufacturing technology
Mold processing technology: Mold processing technology includes cutting, grinding, electric discharge machining, etc. In the processing process, it is necessary to strictly control the processing accuracy and surface quality to ensure the accuracy and life of the mold.
Mold assembly technology: Mold assembly is an important part of the mold manufacturing process. In the assembly process, it is necessary to ensure the coordination accuracy and assembly quality between the parts of the mold to ensure the overall performance of the mold.
Mold debugging technology: Mold debugging is a necessary step in the mold manufacturing process. In the debugging process, the mold needs to be tested and corrected to ensure that the mold can meet the requirements of forging processing.
Mold inspection technology: Mold inspection technology is an important means to ensure mold quality. By using advanced testing equipment and methods, the dimensional accuracy, surface quality and internal quality of the mold can be comprehensively tested to ensure that the quality of the mold meets the requirements.
Die design and manufacturing technology is an indispensable and important link in forging processing. The quality and production efficiency of forgings can be significantly improved by rational design of die structure and selection of suitable manufacturing technology. In the future, with the continuous development and innovation of technology, it is believed that mold design and manufacturing technology will be more advanced and efficient, providing strong support for the development of forging processing.
