A cross plate 64 is fixedly mounted on the left end face of the upper limiting plate 61, and a cutting plate 65 is fixedly mounted on the bottom end of the cross plate 64. The width of the lower limiting plate 62 in the front-to-back direction is smaller than that of the upper limiting plate 61. The bottom of the upper limiting plate 61 and the cutting plate 65 extends to the interior of the processing table 2, and the bottom of the rolling ball 63 and the cutting plate 65 are in adaptive contact with the sheet metal 8. The lower limiting plate 62 and the rolling ball 63 can limit the top of the sheet metal 8, and the plate 65 can cut the sheet metal 8 after punching. A reinforcing rib 1 is fixedly mounted between the bottom end of the cross plate 64 and the left end face of the upper limiting plate 61, and the reinforcing rib 1 can stabilize the cutting plate 65 during cutting.

[0025] Reference Figure 3 Figure 4The front and rear direction limiting assembly 7 includes two hollow plates 71 fixedly mounted on the front and rear sides of the processing table 2. A support rod 72 is fixedly mounted on the bottom of the hollow plate 71. A friction plate 73 is slidably connected to the surface of the support rod 72. A telescopic rod 74 is fixedly mounted on the left and right sides of the hollow plate 71. The two ends of the telescopic rod 74 are respectively fixedly connected to the hollow plate 71 and the proximal ends of the friction plate 73. The end of the friction plate 73 away from the telescopic rod 74 is in adaptive contact with the side wall of the sheet metal part 8. The front and rear friction plates 73 can limit the front and rear directions of the sheet metal part 8 so that the sheet metal part 8 will not shake in the front and rear directions during movement. A pressure spring 75 is wound around the surface of the telescopic rod 74. A slider 76 is slidably connected to the side of the hollow plate 71 near the sheet metal part 8. The side of the hollow plate 71 close to the sheet metal 8 is fixedly mounted with a driven plate 77, and the side of the hollow plate 71 close to the sheet metal 8 is provided with a cross slot, and the slider 76 is slidably connected to the inside of the cross slot, and a reinforcing rib 2 is fixedly connected between the slider 76 and the driven plate 77, and the bottom end of the slider 76 is rotatably connected to the telescopic rod 2 78, and the surface of the telescopic rod 2 78 is fixedly connected to the pressure spring 2 79, and the top of the driven plate 77 is adapted to contact with the bottom end of the upper limiting plate 61. When the upper limiting plate 61 moves downward, it presses the driven plate 77 downward. At this time, the driven plate 77 remains horizontal under the support of the reinforcing rib 2, and the bottom end of the pressure spring 2 79 is rotatably connected to the side of the friction plate 73 away from the sheet metal 8. When the slider 76 moves downward, it pushes the friction plate 73 to press against the side of the sheet metal 8 through the telescopic rod 2 78 and the pressure spring 2 79.

[0026] Working principle: The operator connects the sheet metal 8 with the traction equipment, and then pulls the sheet metal 8 to move inside the processing table 2, and at the same time drives the hydraulic rod 3 to drive the pressure plate 4 to move up and down reciprocatingly. When the pressure plate 4 moves downward, it will drive the upper limiting plate 61 and the lower limiting plate 62 to move downward. At this time, the ball 63 at the bottom of the lower limiting plate 62 rolls on the top of the sheet metal 8. At this time, the sheet metal 8 will not shake in the up and down directions. When the upper limiting plate 61 moves downward, it will push the driven plate 77 to move downward. At this time, the driven plate 77 will drive the slider 76 to move downward. As the slider 76 approaches the friction plate 73, the slider 76 will push The movable telescopic rod 2 78 then pushes the friction plate 73 away from the hollow plate 71. At this time, the friction plate 73 will stretch the telescopic rod 1 74 and the pressure spring 1 75 on the surface of the support rod 72 and approach the side of the sheet metal 8 until the front and rear friction plates 73 are respectively limited to the front and rear sides of the sheet metal 8. At this time, the sheet metal 8 is pulled and slides between the two friction plates 73, so the sheet metal 8 will not shake in the front and rear directions; at the same time, the pressure plate 4 will drive the punch rod 5 to move downward and punch the sheet metal 8, and the up and down directions and front and back directions of the sheet metal 8 are limited, so the punch rod 5 can punch the sheet metal 8 stably.

[0027] Afterwards, the hydraulic rod 3 drives the pressure plate 4 to move upward, and the sheet metal 8 continues to move in the left and right directions. Then, the hydraulic rod 3 drives the pressure plate 4 to move downward again to continuously punch the sheet metal 8 back and forth. When the upper limiting plate 61 moves downward, it will drive the cross plate 64 and the cutting plate 65 to move downward. At this time, the cutting plate 65 cuts the punched sheet metal 8, so that the punched part of the sheet metal 8 is cut, thereby obtaining the processed sheet metal.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
