However, the stamping machine of the above-mentioned device will generate large vibrations when moving downward to stamp the workpiece. The above-mentioned device lacks a buffering and shock-absorbing device for the stamping table on the metal stamping device body, resulting in the vibration generated by the stamping machine being transmitted to the metal stamping device body, causing the entire device to shake.

[0006] 2. In addition, the first limit plate and the second limit plate on both sides of the stamping table in the above-mentioned device are fixedly installed on the metal stamping device body, resulting in that only workpieces of specified sizes can be placed in the rectangular groove opened between the two. The above-mentioned device cannot adjust the distance between the first limit plate and the second limit plate, thereby being unable to ensure that workpieces of different sizes can be placed in the rectangular grooves on both sides. Utility Model Content

[0007] The present utility model provides an intelligent digital metal stamping device, which aims to solve the problem mentioned in the above background technology that the stamping machine of the above device will generate large vibrations during operation.
