Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of forging processing and relates to a punching device used for forging processing. Background Art
[0002] During the forging process, the purpose of punching is several aspects. First, punching can create conditions in advance for subsequent processing steps such as cutting, drilling and riveting. By forming holes in the forging, these operations can be completed more conveniently and quickly, while also improving the accuracy and efficiency of the processing. Secondly, the skinned part left after punching can retain a portion of the original material, thereby enhancing the tensile strength and hardness of the forging. This treatment method helps to improve the quality and reliability of the forging, making it less likely to deform or break when subjected to external forces. The punching operation in the forging process is crucial to the quality and performance of the product. If the punching operation cannot be carried out continuously, it may cause a series of problems, as follows:
[0003] Since the continuity of the punching operation is interrupted, the starting and ending points of each punching may be inconsistent, resulting in different shapes and sizes of the holes, and may even cause defects such as burrs and tears. Discontinuous punching operations may cause stress changes inside the material. If the stress distribution is uneven, the forging may cause deformation, cracking and other problems during subsequent processing or use.
[0004] During the punching process, the mold and tool are constantly impacted and worn. If the punching operation is discontinuous, the local parts of the mold may be oxidized or corroded due to long-term exposure to the air, further exacerbating its wear and tear. Due to the need to frequently start and stop the punching equipment and adjust the punching position, the overall production efficiency is reduced and the production cost increases accordingly.
[0005] Due to problems such as uneven hole quality and increased internal stress in materials, the performance of forgings may be reduced and the product qualification rate may be reduced. This not only affects the economic benefits of the enterprise, but also may bring hidden dangers to the safety of products or equipment using these forgings. Discontinuous punching operations may increase the work intensity of workers, requiring constant attention to equipment status and adjustment of punching parameters, which increases the labor intensity of workers.
[0006] In order to ensure the smooth progress of punching operations in forging processing, punching equipment, dies and tools should be regularly inspected and maintained to keep them in good working condition. Therefore, there is an urgent need for a punching device for forging processing to solve the above problems. Utility Model Content
