[0004] The punch in the above scheme is located in the shell, so that the protection of the four sides can be realized by only lifting the protection plate on one side. However, since the punch is arranged in the shell, although the operator can be protected from potential injury when the punch is running, the operator's vision may be blocked, making it difficult to observe the working state of the punch and the stamping process of the metal plate comprehensively, which may affect the accuracy and timeliness of the operation. In addition, the closed nature of the case may make it difficult to effectively dissipate the heat generated by the punch during long-term operation, requiring additional cooling equipment.
