The thin-wall forming technology of the forging die of construction machinery refers to the thin-wall forming of the forging by changing the mold structure and manufacturing process in the forging process. This technology is mainly used in the manufacturing of construction machinery forgings that require lightweight, high strength and high stiffness.
The research of thin-wall molding technology involves the following aspects:
- Mold material selection: select high strength, high temperature deformation resistance and wear resistance materials as mold manufacturing materials to ensure the stability and life of the mold under high temperature and high stress.
- Mold structure design: According to the shape, size and wall thickness requirements of the forging, design a mold structure suitable for thin-wall forming. Including mold geometry, cooling system, support structure, etc.
- Mold manufacturing process: The use of advanced CNC machining technology and precision manufacturing technology to ensure that the size and shape accuracy of the mold meet the requirements. At the same time, it is also necessary to consider the process steps such as surface treatment and heat treatment of the mold.
- Mold test and verification: carry out mold test to verify the performance and stability of the mold. According to the test results, the mold structure and manufacturing process were adjusted and improved to improve the success rate and quality of thin-wall forming.
Through the study of thin-wall molding technology, the lightweight design and production of construction machinery forgings can be realized, the strength, stiffness and fatigue life of forgings can be improved, the material and production costs can be reduced, and the overall performance and competitiveness of construction machinery can be improved. This technology has a broad application prospect in the field of construction machinery manufacturing.
