L-shaped protective plates 11 are provided on both sides of the shearing knife 4, and two baffles 5 are fixedly connected on both sides of the L-shaped protective plate 11. Since the two L-shaped protective plates are moved away from each other when the shearing knife is lowered, and the two L-shaped protective plates are moved close to each other when the shearing knife is raised, the shearing knife can be wrapped and protected, which effectively solves the problem that most of the metal sheet shearing machines in the prior art lack protective devices when not in use, and the shearing knife is still exposed when not in use. The staff is very likely to be scratched by the shearing knife due to negligence during the loading and unloading process, which will cause harm to the health of the staff, thereby achieving the technical effect of reducing operation risks, improving work safety, protecting the health of staff, and improving work efficiency.
[0023] In this embodiment, two limit rods 12 are fixedly connected to the top of the mounting plate 3, and a first limit groove 13 is opened at the position of the limit rod 12 on the shearing machine body 1. The limit rod 12 is arranged in the first limit groove 13, and the limit rod 12 is slidably connected to the shearing machine body 1.
[0024] In this embodiment, four second limit grooves 14 in a square layout are opened on the operating table of the shearing machine body 1, and connecting rods 15 are arranged in the four second limit grooves 14. The connecting rods 15 are slidably connected to the shearing machine body 1, and the tops of the two connecting rods 15 on the same side are fixedly connected to the same pressure plate 16.
[0025] In this embodiment, the bottoms of the two connecting rods 15 on the same side are fixedly connected to the same bottom plate 17 , and the two bottom plates 17 are fixedly connected to the same connecting plate 18 on the sides close to each other.
[0026] In this embodiment, a screw rod 19 is passed through the connecting plate 18 , a motor 20 is disposed at the bottom of the screw rod 19 , and an output shaft of the motor 20 is fixedly connected to the screw rod 19 .
[0027] In this embodiment, the motor 20 is fixedly connected to the shearing machine body 1 .
[0028] Working principle: When using this device, the metal sheet to be sheared can be placed on the operating table of the shearing machine body 1, and the position to be sheared can be placed at the bottom of the shearing knife 4, and then the motor 20 can be started, and the output shaft of the motor 20 can drive the screw rod 19 to rotate, and the screw rod 19 can drive the connecting plate 18 to descend, and the descent of the connecting plate 18 can drive the bottom plate 17 to descend, and the descent of the bottom plate 17 can drive the connecting rod 15 to descend, and the descent of the connecting rod 15 can drive the pressing plate 16 to descend, and the pressing plate 16 can descend until it contacts the metal sheet, so that the metal sheet can be pressed and fixed, and then the cylinder 2 can be started, and the output end of the cylinder 2 can drive the mounting plate 3 to descend, and the mounting plate 3 can drive the shearing knife 4 to descend and approach the metal sheet, and when the mounting plate 3 descends and contacts the baffle 5 and continues to descend, the mounting plate 3 can squeeze the two baffles 5, and the two baffles 5 can gradually move away from each other, and the two baffles 5 can squeeze the spring 9 to contract the spring 9, and at the same time the baffle 5 can also drive L The L-shaped protective plate 11 moves away from the shearing knife 4. After the mounting plate 3 moves past the bevel 6, the L-shaped protective plate 11 will be completely away from the shearing knife 4. At this time, the shearing knife 4 continues to descend to shear the metal sheet. After the shearing is completed, the output end of the cylinder 2 is contracted, so that the mounting plate 3 can be raised, and the mounting plate 3 will drive the shearing knife 4 to rise. When the mounting plate 3 contacts the bevel 6 again and continues to rise, the spring 9 will gradually extend, and the spring 9 will push the baffle 5, and the baffles 5 on both sides will approach each other, and the baffle 5 will drive the L-shaped protective plate 11 to move close to the shearing knife 4. When the shearing knife 4 moves back to its original position, the two L-shaped protective plates 11 contact each other to wrap up the shearing knife 4, so as to prevent the shearing knife 4 from scratching the staff during loading and unloading. The staff can be more assured and focused on their work, thereby improving work efficiency and production quality. Subsequently, the output shaft of the motor 20 is reversed, so that the pressing plate 16 can be raised, and the sheared sheet can be taken out.
