Moreover, if the metal debris during the operation is not cleaned in time, it will affect the subsequent punching operations. In this application, the auxiliary device is used. The steel to be punched is placed on the conveyor roller 2, and the first drive motor 3 drives the conveyor roller 2 to rotate, causing the steel to move to the top of the lifting seat 404. The first hydraulic cylinder 402 on the fixed frame 401 operates, and the first hydraulic rod 403 pushes the lifting seat 404 upward to a suitable position. Then, the second hydraulic cylinder 415 inside the lifting cavity 414 is started, and the second hydraulic rod 416 pushes the lifting rod 417 upward to the highest position.

[0028] Working principle: In the shipbuilding industry, in order to ensure the smooth assembly of steel materials, a punching device is required to perform punching operations on the plates for installation, ventilation, or other required purposes to ensure the subsequent production and assembly operations. When the existing steel structure steel punching device is in use, the punching position will deform due to the impact pressure, inevitably damaging the plates. Moreover, if the metal debris during the operation is not cleaned in time, it will affect the subsequent punching operations. In this application, the auxiliary device is used. The steel material to be punched is placed on the conveyor roller 2, and the first drive motor 3 drives the conveyor roller 2 to rotate, causing the steel material to move to the top of the lifting seat 404. The first hydraulic cylinder 402 on the fixing frame 401 operates, and the first hydraulic rod 403 pushes the lifting seat 404 upward to an appropriate position. Then, the second hydraulic cylinder 415 inside the lifting cavity 414 is started, and the second hydraulic rod 416 pushes the lifting rod 417 upward to the highest position. Immediately afterwards, the telescopic cylinder 418 operates, and the telescopic rod 419 pushes the clamping plate 420 to clamp on both sides of the steel material. Then, the small motor 409 is started, the screw rod 408 rotates, and the lifting block 407 inside the lifting groove 406 drives the lifting frame 410 to move downward, causing the pressing plate 411 to tightly press on the steel material, avoiding the phenomenon of deformation of the plate during punching and ensuring the quality of the plate. As the punching mechanism 7 on the mounting frame 6 operates, the metal debris generated by punching the plate enters the inside of the material receiving hopper 506 through the structure hole 405. The metal debris falls on the conveyor belt 502, and the second drive motor 503 on the connecting frame 501 operates, causing the conveyor belt 502 to rotate, and the metal debris is pushed towards the guiding plate 504, achieving the rapid cleaning of the metal debris.
