[0022] Please refer to Figures 2-3In the embodiment, the four groups of moving tracks 4 are arranged along the front and rear ends of the two groups of fixed blocks 3, the surfaces of the four groups of moving tracks 4 are provided with moving sliding grooves 5, the ends of the two groups of moving tracks 4 away from the fixed blocks 3 are provided with fixed rods 10, the other two groups of moving tracks 4 are arranged in the same way as the two groups of moving tracks 4, the lower ends of the four groups of moving tracks 4 are provided with inclined supporting rods 9, one end of the inclined supporting rod 9 is connected with the moving track 4, the other end of the inclined supporting rod 9 is connected with the fixed block 3, the lower ends of the two groups of fixed rods 10 are symmetrically provided with two groups of supporting legs 11, the supporting legs 11 can be matched with the fixed rods 10 to support the folded plate 1 through the combination of the inclined supporting rods 9 and the supporting legs 11, the moving tracks 4 are supported through the inclined supporting rods 9 to avoid the edge lifting of the bending mechanism 6 due to gravity deviation during bending, and the bending mechanism 6 can slide through the moving sliding grooves 5 of the moving tracks 4 to adjust the bending depth of the pins according to the combination of the moving tracks 4 and the moving sliding grooves 5.

[0023] Please refer to Figures 2-3 In the embodiment, the surface of the resistance fixed plate 2 is provided with a plurality of resistance fixed grooves 7, the plurality of resistance fixed grooves 7 are uniformly distributed on the surface of the resistance fixed plate 2, and the front and rear ends of the plurality of resistance fixed grooves 7 are provided with pin fixed grooves 8. Through the combination of the resistance fixed grooves 7 and the pin fixed grooves 8, when the resistance elements are bent, the workers put a plurality of resistance elements into the resistance fixed grooves 7 in sequence, so that the pins at both ends of the resistance elements extend above the pin bending groove 12 from the pin fixed groove 8. The sides of the resistance fixed plate 2 are provided with pin bending grooves 12 corresponding to the pin fixed grooves 8, the connection between the pin fixed grooves 8 and the pin bending grooves 12 is provided with a bending chamfer 13, through the combination of the pin bending groove 12 and the bending chamfer 13, after the pin extends above the pin bending groove 12, the bending mechanism 6 applies pressure to the pin, so that the end of the pin away from the resistance element is pressed into the pin bending groove 12 for bending, and the bending chamfer 13 makes the pin bend more uniformly and smoothly during bending, reduces deformation and stress concentration during bending, and avoids the pin from breaking during bending.

[0024] Please refer to Figures 3-4In the embodiment, the lower end of the pressing rod 14 is linearly provided with a plurality of sets of bending pressing blocks 15 corresponding to the pin bending grooves 12. The bottom front end of each bending pressing block 15 is provided with a bending chamfer 16. An upper portion of the bending chamfer 16 is provided with a vertical top edge 17. The bending chamfer 16 and the vertical top edge 17 are combined to enable the bending pressing block 15 to press the pin into the pin bending groove 12. The bending chamfer 16 first presses the pin to a certain angle by the chamfer structure, and then the vertical top edge 17 presses the pin into the pin bending groove 12, so that the pin is bent vertically twice, thereby reducing the bending impact force of the pin and protecting the pin. The upper ends of the two ends of the pressing rod 14 are provided with connecting rods 18. The upper end of each connecting rod 18 is provided with a connecting block 19. One end of the connecting block 19 is connected to the connecting rod 18. The other end of the connecting block 19 is provided with a telescopic pressing shaft 20 below. The lower end of the telescopic pressing shaft 20 is provided with a sliding seat 22.

The outer end of the telescopic pressing shaft 20 is provided with a reset spring 21. The inside of the reset spring 21 is provided with a damper. The telescopic pressing shaft 20 and the reset spring 21 are combined to enable the worker to press the pressing rod 14 when bending, so that the telescopic pressing shaft 20 extends to press the bending pressing block 15 into the pin bending groove 12. After the bending is completed, the reset spring 21 returns to reset the bending pressing block 15 to the original position.

[0025] When working, the worker puts a plurality of resistance elements into the resistance fixing groove 7 in sequence, so that the pins at both ends of the resistance element extend from the pin fixing groove 8 to above the pin bending groove 12, and then the bending mechanism 6 is slid along the moving sliding groove 5 of the moving rail 4 through the moving block 23.

[0026] Then the worker presses the pressing rod 14, so that the telescopic pressing shaft 20 extends to press the bending pressing block 15 into the pin bending groove 12. When the bending pressing block 15 presses the pin into the pin bending groove 12, the bending chamfer 16 first presses the pin to a certain angle by the chamfer structure, and then the vertical top edge 17 presses the pin into the pin bending groove 12, so that the pin is bent vertically twice, thereby reducing the bending impact force of the pin.

[0027] At the same time, the bending chamfer 13 enables the pin to bend more uniformly and smoothly during the bending process, reduces deformation and stress concentration during the bending process, avoids the pin from breaking during the bending process, and enables the reset spring 21 to return to reset the bending pressing block 15 to the original position after the bending is completed.

[0028] Through the above steps, the application is combined with the bending plate 1, the resistance fixed plate 2, the moving track 4 and the bending mechanism 6, so that when the resistance pin is bent, the workers put the multiple resistance elements into the resistance fixed groove 7 in turn, make the pins at both ends of the resistance element extend from the pin fixed groove 8 to the top of the pin bending groove 12, then make the bending mechanism 6 slide through the moving sliding block 23 along the moving sliding groove 5 of the moving track 4, then the workers press the pressing rod 14, make the telescopic pressing shaft 20 extend and retract to press the bending pressing block 15 into the pin bending groove 12, when the bending pressing block 15 presses the pin into the pin bending groove 12, the bending cutting corner 16 first presses the pin to a certain angle through the cutting corner structure, then the vertical top edge 17 presses into the pin bending groove 12, the pin is bent vertically for the second time, so that the pin bending impact force can be slowed down, through this relatively simple structure, the production cost of the pin bending device is greatly reduced, and the problem that the daily maintenance and fault diagnosis become more difficult is avoided.
