[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a bending device for workpiece processing, including a work plate 1, a support frame 2 fixedly installed at the bottom of the work plate 1, a fixed bending mechanism 3 fixedly installed on one side of the top of the work plate 1 that contacts one side of the workpiece, a movable bending mechanism 4 slidably installed on the top of the work plate 1 that cooperates with the fixed bending mechanism 3 to bend and form the workpiece, an adsorption positioning mechanism 6 is provided on both sides of the fixed bending mechanism 3 for adsorbing and positioning the workpiece, and a position adjustment mechanism 5 is provided on both sides of the fixed bending mechanism 3 to ensure that the adsorption positioning mechanism 6 is always adsorbed and positioned with the workpiece.

[0018] The adsorption positioning mechanism 6 can adsorb and position the round tube workpiece that needs to be bent. The moving bending mechanism 4 can then move towards the fixed bending mechanism 3, so that the round tube workpiece adsorbed by the adsorption positioning mechanism 6 can be bent. When the round tube workpiece is subjected to compression and bending, the position adjustment mechanism 5 can move the adsorption positioning mechanism 6 back and forth and left and right, so as to ensure that the adsorption positioning mechanism 6 can always adsorb and position the round tube workpiece during bending.

[0019] Please see Figure 1 and Figure 2The movable bending mechanism 4 includes a slide rail 7, a slider 8, a movable bending die 9, a connecting claw 10, and a drive cylinder 12. Two sets of slide rails 7 are fixedly installed on the top of the work plate 1. The movable bending die 9 is slidably connected to the slide rails 7 via the slider 8. The drive cylinder 12 is fixedly installed on the top of the work plate 1 via a mounting bracket 11. The connecting claw 10 is fixedly installed on one side of the movable bending die 9. The output end of the drive cylinder 12 is fixedly connected to the connecting claw 10. The fixed bending mechanism 3 includes a support block 13, a fixed bending die 14, a first connecting bracket 15, and a positioning bracket 16. The fixed bending die 14 is fixedly connected to the top of the work plate 1 via two sets of support blocks 13. The first connecting bracket 15 is fixedly installed on the top of the work plate 1 and on one side of the fixed bending die 14. Multiple positioning brackets 16 that contact one side of the fixed bending die 14 are fixedly installed on the top of the first connecting bracket 15.

[0020] After the adsorption positioning mechanism 6 completes the adsorption positioning of the round tube workpiece, the drive cylinder 12 can push the connecting claw 10, the moving bending die 9 and the slider 8 to move along the slide rail 7. In this way, the moving bending die 9 and the fixed bending die 14 can cooperate with each other to complete the bending process of the round tube workpiece. The first connecting frame 15 and the positioning frame 16 can support one side of the fixed bending die 14 to prevent the fixed bending die 14 from shifting when the round tube workpiece is bent.

[0021] Please see Figure 1 and Figure 3 The adsorption positioning mechanism 6 includes a moving rod 21, a second connecting frame 22, an adsorption frame 26, adsorption holes 27, and a vacuum tube 28. The moving rod 21 is fixedly installed on one side of the adsorption frame 26. Multiple sets of adsorption holes 27 are opened on one side of the adsorption frame 26. A vacuum tube 28 communicating with the adsorption holes 27 is fixedly connected to one side of the adsorption frame 26. The second connecting frame 22 is fixedly installed on the outside of the moving rod 21.

[0022] The adsorption frame 26 can contact the outer wall of the cylindrical workpiece, and then the vacuum tube 28 is connected to the external vacuum equipment. In this way, the vacuum can be drawn using the adsorption hole 27, so that the cylindrical workpiece can always be in contact with the inner wall of the adsorption frame 26 for adsorption.

[0023] Please see Figure 1 , Figure 2 and Figure 3The position adjustment mechanism 5 includes a first fixed plate 17, a first slide rod 18, an adjustment frame 19, a first spring 20, a second fixed plate 23, and a second slide rod 24. The first fixed plate 17 is mounted on the fixed bending die 14. The first slide rod 18 is fixedly mounted on the first fixed plate 17. The adjustment frame 19 is slidably connected to the outside of the first slide rod 18. The first spring 20 is fixedly connected to one side of the first fixed plate 17 and outside the first slide rod 18. One end of the first spring 20 is fixedly connected to the adjustment frame 19. One side of the adjustment frame 19 is in contact with the fixed bending die 14. 21 is inserted into the adjustment frame 19. A second connecting frame 22 is fixedly installed on the outside of the moving rod 21. Multiple sets of limiting balls 29 that contact the two sides of the adjustment frame 19 are rotatably installed on the inner wall of the second connecting frame 22. A second fixing plate 23 is fixedly installed on the top of the adjustment frame 19. A second sliding rod 24 is slidably connected on the second connecting frame 22. One end of the second sliding rod 24 is fixedly connected to the second fixing plate 23. A second spring 25 is fixedly connected to one side of the second fixing plate 23 and outside the second sliding rod 24. One end of the second spring 25 is fixedly connected to the second connecting frame 22.

[0024] When the fixed bending die 14 and the moving bending die 9 extrude and form the round tube workpiece, they will cause a certain amount of tension on the workpiece. At this time, the movable rod 21 and the second connecting frame 22 can move along the inner and outer walls of the adjusting frame 19. The limiting ball 29 can facilitate the smoother movement of the movable rod 21 and the second connecting frame 22. The second spring 25 can drive the movable rod 21 and the second connecting frame 22 to reset after the workpiece is removed. This makes it convenient for the movable rod 21 to move left and right during bending. When the movable rod 21 needs to move back and forth, the adjusting frame 19 can move back and forth along the outside of the first sliding rod 18. The first spring 20 can drive the movable rod 21 to reset after the workpiece is removed.

[0025] Please see Figure 2 The support block 13 is connected to the fixed bending die 14 by the second locking bolt 31, and the slider 8 is connected to the moving bending die 9 by the first locking bolt 30. The fixed bending die 14 and the moving bending die 9 connected by the second locking bolt 31 and the first locking bolt 30 are convenient for replacement and maintenance.

[0026] In use, firstly, the adsorption positioning mechanism 6 can adsorb and position the round tube workpiece that needs to be bent. Then, the movable bending mechanism 4 can move towards the fixed bending mechanism 3, allowing the round tube workpiece adsorbed by the adsorption positioning mechanism 6 to be bent. When the round tube workpiece is being bent under pressure, the position adjustment mechanism 5 can move the adsorption positioning mechanism 6 forward, backward, left, and right, ensuring that the adsorption positioning mechanism 6 always adsorbs and positions the round tube workpiece during bending. After the adsorption positioning mechanism 6 completes the adsorption and positioning of the round tube workpiece, the drive cylinder 12 can push the connecting claw 10, the movable bending die 9, and the slider 8 along the slide rail 7. This allows the movable bending die 9 and the fixed bending die 14 to work together to complete the bending of the round tube workpiece. The first connecting frame 15 and the positioning frame 16 can support one side of the fixed bending die 14 to prevent displacement of the fixed bending die 14 during the bending process. The adsorption frame 2... 6 can contact the outer wall of the round tube workpiece, and then the vacuum tube 28 is connected to the external vacuum equipment, so that vacuum can be drawn using the adsorption hole 27. This ensures that the round tube workpiece is always in contact with the inner wall of the adsorption frame 26. When the fixed bending die 14 and the moving bending die 9 extrude and form the round tube workpiece, they will cause a certain amount of tension on the workpiece. At this time, the moving rod 21 and the second connecting frame 22 can move along the inner and outer walls of the adjustment frame 19. The limiting ball 29 can facilitate smoother movement of the moving rod 21 and the second connecting frame 22. The second spring 25 can drive the moving rod 21 and the second connecting frame 22 to reset after the workpiece is removed. This allows the moving rod 21 to move left and right during bending. When the moving rod 21 needs to move back and forth, the adjustment frame 19 can move back and forth along the outside of the first sliding rod 18. The first spring 20 can drive the moving rod 21 to reset after the workpiece is removed.
