With the rapid development of construction machinery industry, construction machinery forgings as one of the key parts, its demand is increasing. The design and manufacturing technology of construction machinery forging die has become an important link to ensure the quality and production efficiency of forging. The following will introduce the design and manufacturing technology of construction machinery forging die in detail.
- Design phase:
In the design of construction machinery forging die, it is necessary to fully consider the shape, size and material of the forging. First of all, the basic shape and structure of the die are determined through the in-depth analysis of the function and use environment of the forging. Then, the CAD software is used for 3D modeling to ensure that the geometry and size of the mold meet the design requirements.
In addition, in the design stage also need to conduct simulation analysis, such as finite element analysis, to determine the deformation and mechanical properties of the forging during the forming process. Through the analysis of the results, the design of the die can be optimized to ensure the formability and quality of the forging.
Second, mold manufacturing:
The manufacturing process of the mold needs to be operated in strict accordance with the design drawings. First of all, according to the design drawings, the structural parts of the mold are made, such as the mold seat, slide block, roof, etc. These components need to have sufficient strength and stability to withstand the requirements of high temperatures and pressures during use.
When choosing die materials, appropriate materials such as high-hardness tool steel should be selected according to the forging process and the requirements of the use environment to ensure the wear resistance and stability of the die. In the manufacturing process, it is necessary to use precision equipment such as CNC machine tools for precise machining to ensure the geometric accuracy and surface quality of the mold.
For large forging dies of construction machinery, it is also necessary to carry out reasonable assembly and debugging. In the assembly process, it is necessary to ensure the coordinated movement and stability between the various parts to avoid interference or deformation problems.
Third, surface treatment:
In order to further improve the performance and service life of the die, appropriate surface treatment can be carried out on the forging die of construction machinery. Common surface treatment methods include heat treatment and surface coating.
Heat treatment mainly includes quenching, tempering and other processes, which can improve the hardness and wear resistance of the mold, and enhance its use ability under high temperature and high pressure conditions.
Surface coating technology is to cover a layer of wear-resistant and corrosion-resistant materials (such as coating alloys, nitriding layers, etc.) on the surface of the mold. This method can effectively improve the wear and corrosion resistance of the mold and extend the service life of the mold.
- Mold test and improvement:
After the manufacturing is completed, it is necessary to carry on the actual production test of the forging die of the construction machinery. Through the test, the performance and reliability of the mold are evaluated, and the existing problems are found in time.
According to the test results and user feedback, the mold can be improved and optimized. Including adjusting the mold structure, improving material selection, optimizing processing technology, etc., to meet the needs of different forging production, and improve the use efficiency and life of the mold.
To sum up, the design and manufacturing technology of construction machinery forging die is a complex and critical process. It is necessary to fully consider the shape, size and material requirements of the forging, and carry out simulation analysis and optimization in the design stage. In the manufacturing process, the appropriate materials are selected, precisely machined, and the appropriate surface treatment is carried out. Through testing and improvement, the performance and reliability of the die are constantly optimized to meet the production requirements of construction machinery forgings.
