A fixed plate 2 is fixedly connected inside the box body 1. The fixed plate 2 provides an installation and support basis for other components, ensuring stability during the working process. A hydraulic cylinder 1 3 is fixedly connected inside the box body 1. The hydraulic cylinder 1 3 can provide a powerful driving force to realize the clamping operation of the sheet metal. The driving end of the hydraulic cylinder 1 3 is fixedly connected with a push plate 4. The push plate 4 can evenly transmit the thrust of the hydraulic cylinder 1 3 to the rotating rod 5. The front and rear ends of the push plate 4 are rotatably connected with the rotating rod 5. The rotation of the rotating rod 5 can realize the position adjustment of the clamping block 7 to adapt to the clamping of sheet metals of different sizes;

[0032] The other ends of the two rotating rods 5 are rotatably connected with sliding blocks 6. The sliding of the sliding blocks 6 can drive the clamping blocks 7 to move, thereby realizing the clamping of the sheet metal. The tops of the two sliding blocks 6 are fixedly connected with clamping blocks 7. The clamping blocks 7 can firmly clamp the sheet metal, ensuring that the sheet metal does not displace during the bending process. A hydraulic cylinder 2 19 is fixedly connected to the top of the box body 1. The hydraulic cylinder 2 19 provides power for the movement of the bending block 20 to realize the bending operation. The driving end of the hydraulic cylinder 2 19 is fixedly connected with a bending block 20. The bending block 20 can perform precise bending processing on the sheet metal. An ejection assembly for ejecting the bent sheet metal is arranged inside the fixed plate 2. The ejection assembly can conveniently eject the bent sheet metal, improving work efficiency. A secondary bending assembly for performing secondary bending on both ends of the sheet metal is arranged inside the box body 1. The secondary bending assembly can meet the complex bending requirements of the sheet metal, improving the processing ability and flexibility of the device.

[0033] Referring to Figure 3 , Figure 4The ejection assembly includes a sliding plate 9, which is slidably connected to the inside of the fixed plate 2. The sliding of the sliding plate 9 can realize the ejection action to push out the bent sheet metal. The top of the push plate 4 is fixedly connected with a push rod 8, and the push rod 8 can transmit the movement of the push plate 4 to the sliding plate 9 to realize linkage. The top of the push rod 8 is provided with a sliding plate 9. The sliding plate 9 can accurately adjust its position under the action of the push rod 8. The top of the sliding plate 9 is slidably connected with a slide plate 11. The sliding of the slide plate 11 can drive the ejector rod 12 to move to realize the ejection function. The top right end side of the sliding plate 9 is rotatably connected with an ejection block 10. The top of the slide plate 11 is fixedly connected with an ejector rod 12. The ejector rod 12 can directly act on the ejection plate 15 to eject the sheet metal. The inner top of the fixed plate 2 is fixedly connected with a limiting rod 14.

[0034] The top of the slide plate 11 is fixedly connected with a spring 13, which can provide a reset force for the slide plate 11 to ensure the smooth progress of the ejection operation. The top of the fixed plate 2 is slidably connected with an ejection plate 15, which can smoothly eject the sheet metal for easy removal. The secondary bending assembly includes two clamping blocks 16, which slide on both sides of the fixed plate 2 respectively. The clamping blocks 16 can clamp and fix the sheet metal for secondary bending. The four internal corners of the box body 1 are fixedly connected with guide rods 17, which can provide precise guidance for the sliding of the clamping blocks 16 to ensure the stability and accuracy of the sliding. The front and rear sides of the bottom ends of the two clamping blocks 16 are fixedly connected with air pumps 18, which can provide power for the movement of the clamping blocks 16 to achieve fast and precise clamping operations.

[0035] Reference Figure 1 , Figure 3 The front side of the box body 1 is rotatably connected with a box door 21. The rotating connection of the box door 21 is convenient for the operator to open and close, and is convenient for maintenance and operation inside the box body 1. The front side of the box door 21 is fixedly connected with a handle 22. The handle 22 provides a convenient fulcrum for the operator to open the box door 21, making the operation easier. The four corners of the bottom end of the box body 1 are fixedly connected with universal wheels 23. The universal wheels 23 enable the entire device to be flexibly moved, which is convenient for use in different workplaces. The right end of the box body 1 is fixedly connected with a push handle 24. The push handle 24 is convenient for the operator to push the device and control the moving direction and speed. The top end of the push rod 8 contacts the bottom end of the sliding plate 9. This contact can effectively transmit the thrust of the push rod 8 to the sliding plate 9, thereby starting the ejection action. The bottom end of the limit rod 14 contacts the top end of the ejection block 10, which can ensure that the ejection block 10 is driven to rotate.

[0036] Reference Figure 2 , Figure 4, one end of the spring 13 away from the slide plate 11 is fixed to the bottom end of the ejector plate 15. The fixed connection of the spring 13 can provide a restoring elastic force for the ejector plate 15 to ensure the smooth progress and reset of the ejection action. The outside of the ejector rod 12 is in contact with the inner wall of the ejector plate 15. The contact between the ejector rod 12 and the ejector plate 15 can accurately transmit the ejection force to the ejector plate 15 to achieve the ejection function. The sliding block 6 slides inside the fixed plate 2. The sliding of the sliding block 6 can drive the clamping block 7 to move, so as to realize the stable clamping of the sheet metal. The clamping block 16 slides outside the guide rod 17. The guide rod 17 can guide the sliding of the clamping block 16 to make its movement smoother and more accurate, ensuring the clamping and secondary bending effects.

[0037] Working principle: When it is necessary to bend the sheet metal, place the sheet metal on the top end of the fixed plate 2. At this time, start the hydraulic cylinder 1 inside the box body 1, which can drive the push plate 4 to move downward, and then drive the rotating rods 5 at both ends to rotate. The other end of the rotating rod 5 is provided with a sliding block 6, and the sliding block 6 slides inside the fixed plate 2, so as to drive the two sliding blocks 6 to move towards the middle, and then drive the clamping block 7 at the top of the sliding block 6 to clamp and fix the sheet metal. At this time, start the hydraulic cylinder 2 19 at the top of the box body 1, which drives the bending block 20 to squeeze downward, and then can squeeze the sheet metal through the bending block 20 to bend the sheet metal. When the bending block 20 drops to a certain position;

[0038] At this time, start the air pump 18 again, which can drive the clamping blocks 16 at both ends of the air pump 18 to slide towards the middle, and then can bend the two ends of the sheet metal again, which can better bend the sheet metal. When the sheet metal bending is completed, the hydraulic cylinder 1 will push the push plate 4 upward, which can drive the push rod 8 to move upward. The push rod 8 can then push the sliding plate 9 inside the fixed plate 2. The sliding plate 9 drives the slide plate 11 to slide upward. The ejector rod 12 will then push the bottom of the ejector plate 15. When the sliding plate 9 rises to a certain height, the limit rod 14 inside the fixed plate 2 will squeeze the ejector block 10 at the top of the sliding plate 9, and then the ejector block 10 will eject the bottom of the slide plate 11, so as to eject the ejector plate 15 for the second time, and then can eject the bent sheet metal for the second time, improving the work efficiency.
