Forging production is an important link in the machinery manufacturing industry, and mold design and manufacturing technology is one of the key technologies. The quality and design level of die directly affect the quality and production efficiency of forgings. This paper aims to discuss the research of die design and manufacturing technology for forging production, and analyze the basic principles of die design, design flow, material selection, manufacturing process and other aspects, so as to provide reference for actual production.
Basic principles of mold design
The principle of rationality: mold design should meet the production requirements and use requirements of forgings, reasonable structure, easy processing and maintenance.
Economic principle: Mold design should take into account manufacturing costs and service life and other factors, as far as possible to reduce production costs and improve production efficiency.
Reliability principle: The mold design should ensure the stability and reliability of the mold to avoid failure or damage in the production process.
Safety principle: Mold design should take into account the safety and health of the operator to avoid safety accidents in the production process.
Mold design process
Analysis of forging drawings: Detailed analysis of the shape, size, material, technical requirements of the forging, to determine the basic structure and size of the mold.
Design the mold structure: According to the analysis results, design the structure and size of the mold, taking into account the flow trajectory of the material and forming quality and other factors.
Select the mold material: according to the working conditions and requirements of the mold, select the appropriate mold material, taking into account the wear resistance, toughness, strength and other factors.
Design mold manufacturing process: according to the structure and materials of the mold, design a reasonable manufacturing process, taking into account the processing accuracy, production efficiency and other factors.
Audit mold design: Audit and evaluate the mold design to ensure the rationality and feasibility of the design.
Manufacturing mold: According to the design requirements and manufacturing process, manufacturing mold and mold testing and debugging, to ensure that the quality and performance of the mold meet the requirements.
Commonly used mold materials are carbon tool steel, alloy tool steel, high-speed steel, cemented carbide and so on. The selection of mold materials should take into account the working conditions, wear resistance, toughness, strength and other factors. For the mold bearing heavy loads and impacts, materials with high toughness and strength should be selected; For molds requiring higher wear resistance, materials with higher hardness and wear resistance should be selected. In addition, factors such as the processing performance and cost of the material should be taken into account.
Mold manufacturing technology mainly includes machining, electric discharge machining, CNC machining and so on. Machining is a common mold manufacturing method, which is suitable for most mold manufacturing; Edm is suitable for machining moulds with complex shapes and materials that are difficult to machine. CNC machining is suitable for molds with high machining accuracy. In the mold manufacturing process, the processing accuracy, production efficiency, manufacturing cost and other factors should be taken into account, and the appropriate manufacturing process and processing method should be selected.
The research of die design and manufacturing technology for forging production is one of the important topics in the machinery manufacturing industry. This paper analyzes the basic principles of mold design, design flow, material selection, manufacturing process and other aspects of the content, to provide reference for practical production. In practical applications, it is necessary to choose the appropriate mold design and manufacturing method according to the specific situation, and constantly improve the quality and performance of the mold to meet the requirements of forging production and market competitiveness. In the future, with the continuous development of science and technology, it is believed that there will be more advanced mold design and manufacturing technology, which will inject new impetus into the development of the forging production industry.
