The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0021] Please refer to Figures 1-5, A fully electric servo numerical control bending machine, including a machine body 1. Inside the machine body 1, a stamping end 6 is provided. At the top of the stamping end 6, a hydraulic rod is fixed by bolts. The bolts connecting the hydraulic rod to the stamping end 6 are set to four, reducing the disassembly steps. On both inner walls of the machine body 1, slide rails 7 are fixed by bolts. On both outer walls of the machine body 1, chute grooves are provided, and the chute grooves are connected to the slide rails 7. Both ends of the stamping end 6 are slidably arranged inside the slide rails 7. At both ends of the stamping end 6, clamping grooves are provided. Inside the chute grooves, a quick-release structure 5 is slidably arranged. One end of the quick-release structure 5 is located outside the chute groove, and the other end is movably clamped with the clamping groove. On the front surface of the machine body 1, a workbench 2 is fixedly connected. On the workbench 2, a pallet 3 is slidably arranged. On the pallet 3, pressing structures 4 are symmetrically distributed. The pressing structures 4 are used for pressing to fix the bent workpiece on the pallet 3.

[0022] Please refer to Figure 2 , The quick-release structure 5 includes a threaded rod 8, a turning handle 9, a connecting end 10, a buckle 11, a driving disk 12, a pushing disk 13, and a pressing disk 14. The threaded rod 8 is rotatably arranged inside the slide rail 7. One end of the threaded rod 8 exposed outside the chute groove is fixedly connected with the turning handle 9. A connecting end 10 is sleeved on the threaded rod 8. Buckles 11 are rotatably arranged on both sides of the connecting end 10 and are symmetrically distributed. The buckle 11 is inclined and one end of the bottom is inward. The buckle 11 is movably clamped with the clamping groove. On one side of the connecting end 10, a pushing disk 13 is rotatably arranged. On one side of the pushing disk 13, a connecting seat 1201 is fixedly connected.

[0023] On one side of the connecting seat 1201, a driving disk 12 is fixedly connected. On the left inner wall of the driving disk 12, symmetrically distributed connecting rods 1202 are fixedly connected. One end of the connecting rod 1202 is fixedly connected with a pressing disk 14. The pressing disk 14 and the pushing disk 13 are coaxially distributed. By rotating the driving disk 12, the driving disk 12 drives the pushing disk 13 and the pressing disk 14 to rotate. On the inner walls of both the pushing disk 13 and the pressing disk 14, protrusions are provided. The protrusion on the pushing disk 13 can push the top of the buckle 11 outward, making the end of the buckle 11 move inward, thus releasing the clamping of the clamping groove. The protrusion on the inner wall of the pressing disk 14 can push the top of the buckle 11 inward, making the end of the buckle 11 move outward, so that the buckle 11 clamps the clamping groove, thereby making the stamping end 6 and the buckle 11 clamped and fixed. When the buckle 11 releases the fixation of the clamping groove, by rotating the turning handle 9, the threaded rod 8 rotates, and the connecting end 10 sleeved on the threaded rod 8 slides outward, making the buckle 11 disengage from the clamping groove, facilitating the staff to disassemble and replace the stamping end 6.

[0024] Please refer to Figure 3 , Figure 4 and Figure 5, the pressing structure 4 includes a connecting block 15, a rotating pull rod 16, a movable rod 17, a pressing plate 18 and a sliding rod 19. The connecting blocks 15 are fixedly connected to the support plate 3 and are symmetrically distributed. The rotating pull rod 16 is rotatably arranged on the top of the connecting block 15. The bottom of the connecting block 15 is fixedly connected with a movable rod 17. The movable rod 17 is slidably arranged in the connecting block 15. One end of the movable rod 17 located in the connecting block 15 is fixedly connected with a pressing plate 18. The top of the pressing plate 18 is fixedly connected with symmetrically distributed sliding rods 19. One end of the sliding rod 19 penetrates through the inner wall of the connecting block 15 and slides out and is exposed on the top of the connecting block 15.

[0025] A limiting groove 1501 is formed in one inner wall of the connecting block 15. A clamping block 1701 is sleeved on the movable rod 17. The clamping block 1701 is adapted to the limiting groove 1501. A spring 20 is arranged between the pressing plate 18 and the inner wall of the top of the connecting block 15. The spring 20 is sleeved on the sliding rod 19. By lifting the rotating pull rod 16, the rotating pull rod 16 drives the movable rod 17 to lift, so that a gap is left between the pressing plate 18 and the support plate 3. The two ends of the workpiece are placed directly below the pressing plate 18. Then release the rotating pull rod 16 so that the pressing plate 18 presses the workpiece again through the resilience of the spring 20 on the sliding rod 19. By rotating the rotating pull rod 16, the clamping block 1701 is clamped into the limiting groove 1501, thus facilitating the replacement of the bent workpiece.

[0026] Please refer to Figure 1 , a movable groove is formed in the center of the workbench 2. The support plate 3 is slidably arranged in the movable groove. Two sides of the support plate 3 are fixedly connected with sliding blocks 302. A sliding groove is formed in the inner wall of the movable groove. The sliding blocks 302 are adapted to the sliding grooves. A hand pull 301 is fixedly connected to the center of the outer wall of one side of the support plate 3. The movable groove and the matching sliding grooves formed on the workbench 2 enable the support plate 3 to slide freely on the workbench 2, facilitating the adjustment of the position according to the size of the workpiece and the processing requirements.

[0027] The specific operation process of this utility model is as follows: When it is necessary to prepare for bending the workpiece, first place the workpiece on the support plate 3 on the workbench 2. At this time, by lifting the rotating pull rod 16, the rotation of the rotating pull rod 16 drives the movable rod 17 to lift, and further enables the pressing plate 18 to move upward in the connecting block 15 through the sliding rod 19. At this time, the spring 20 is compressed. Subsequently, place the two ends of the workpiece at appropriate positions below the pressing plate 18 and release the rotating pull rod 16. Due to the resilience of the spring 20, the pressing plate 18 will quickly descend and tightly press on the workpiece, thereby realizing the fixation of the workpiece. After the workpiece is fixed, the bending machine starts to perform the bending operation. At this time, the telescopic movement of the hydraulic rod drives the stamping end 6 to slide in the machine body 1 along the slide rail 7 to perform precise bending actions;

[0028] Secondly, the clamping grooves at both ends of the stamping end 6 are movably clamped with the buckles 11 in the quick-release structure 5 to ensure the stability and accuracy of the stamping end 6 during the sliding process. When it is necessary to adjust the stamping end 6 or perform maintenance, by rotating the driving disk 12, the rotation of the driving disk 12 drives the push disk 13 and the pressure disk 14 to rotate synchronously. The protrusion on the push disk 13 pushes the top of the buckle 11 outwards, causing the end of the buckle 11 to move inwards, thereby releasing the clamping of the clamping groove. Subsequently, rotate the rotating handle 9. The rotation of the rotating handle 9 drives the threaded rod 8 to rotate within the slide rail 7, and further causes the connecting end 10 sleeved on the threaded rod 8 to slide outwards. Since the connecting end 10 is connected to the buckle 11, the buckle 11 also moves outwards accordingly and finally disengages from the clamping groove. Subsequently, the staff removes the bolts at the connection between the hydraulic rod and the stamping end 6. There are four bolts, which reduces the disassembly steps, thus realizing the quick disassembly of the stamping end 6. When the bending operation is completed and it is necessary to replace the workpiece or perform other operations, the pallet 3 can be easily taken out by grasping the hand draw 301, and the pallet 3 slides out along the movable groove and the sliding groove on the workbench 2.

[0029] The above exemplary description of the present invention is made in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
