Background technique

In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved by mechanical processing through various mold applications. Its use is becoming more and more extensive; but in the traditional punching machine, it is difficult to ensure the stability of the entire stamping punch during the pressing process, because a large azimuth deviation occurs, and serious cases may directly lead to the scrapping of the workpiece, while the previous stamping die base is also the same. It is difficult to fine-tune the height or level. Because the uneven placement of the workpiece will also affect the stamping result, the actual stamping effect is very poor. At the same time, the strong vibration of the machine body during the stamping process is likely to cause damage to the inner cavity components. solve.
