On the top of the base 1, a box 2 for placing the iron sheet to be processed is fixedly installed. The design of this box 2 aims to provide a stable working platform to ensure the stability and accuracy of the iron sheet during the corner cutting operation. In order to accurately cut the corners of the iron sheet, a frame 7 is fixedly arranged on one side of the top of the base 1. On the frame 7, two L-shaped brackets 5 are installed, which serve as the support structure of the air cylinder and the cutting knife. An air cylinder is fixedly installed on the top of each L-shaped bracket 5, and the telescopic part of the air cylinder penetrates the top of the L-shaped bracket 5 and is connected to a concave seat 19.

In addition, the bottom of the cutting plate 6 is flush with the top of the frame 7 to maintain the stability of the operation.

[0029] In order to ensure the positioning accuracy of the iron sheet during the corner cutting process, two limiting plates 3 are arranged on the top of the box 2, which can automatically limit the two ends of the iron sheet. In order to realize the adjustment of the limiting plate 3, a first adjusting mechanism is provided. The first adjusting mechanism comprises a first motor 4 and a first bidirectional screw rod 14. A through hole is provided on the top of the box 2, and the two limiting plates 3 are L-shaped, one end of which is located in the through hole, and the bottom end is slidably connected with the inner wall of the bottom of the box 2. One side of the first motor 4 is fixedly connected with one side of the box 2, and the two ends of the first bidirectional screw rod 14 are rotatably connected with the inner walls of the two sides of the box 2. The output end of the first motor 4 penetrates one side of the box 2 and is fixedly connected with one end of the first bidirectional screw rod 14. In this way, when the first motor 4 works, it can drive the limiting plate 3 to slide in the through hole by driving the rotation of the first bidirectional screw rod 14, thereby realizing the accurate adjustment of the position of the two ends of the iron sheet.

[0030] In addition, a second adjusting mechanism is arranged for adjusting the cutting plate 6 and the cutting knife 18 on the two L-shaped frames 5. The second adjusting mechanism comprises a concave plate 10, a second motor 9, a second bidirectional screw rod 13, two moving blocks 11 and two connecting plates 12. One side of the concave plate 10 is fixedly connected with one side of the base 1, and the output end of the second motor 9 is fixedly connected with one side of the concave plate 10. The concave plate 10 is designed in a concave shape, and the two ends of the second bidirectional screw rod 13 are rotatably connected with the inner walls of the two sides of the concave plate 10. The output end of the second motor 9 penetrates one side of the concave plate 10 and is fixedly connected with one end of the second bidirectional screw rod 13. The bottoms of the two moving blocks 11 are slidably connected with the bottom inner wall of the concave plate 10, and one side of the moving block 11 is embedded with a second screw nut and is threadedly connected with the second bidirectional screw rod 13. In this way, when the second motor 9 works, it can drive the moving block 11 to slide in the concave plate 10 by driving the rotation of the second bidirectional screw rod 13. One end of the connecting plate 12 is fixedly connected with the top of the moving block 11, and the other end is fixedly connected with one side of the L-shaped frame 5. Therefore, the sliding of the moving block 11 can drive the L-shaped frame 5 and the cutting plate 6 and the cutting knife 18 thereon to move together, so as to realize the accurate adjustment of the cutting angle position.
