Description

Technical Field

[0001] This utility model relates to the technical field of clamping mechanisms for bending machines, specifically a clamping mechanism for bending machines. Background Technology

[0002] A bending machine is a specialized piece of equipment that uses mechanical force to plastically deform metal materials. Its core technologies include two principles: roller extrusion and die forming. The operation process has been highly automated. Generally, the bending of the two ends of long strip-shaped workpieces is achieved by using roller extrusion to provide rotational power.

[0003] When processing long, strip-shaped workpieces, the workpiece body is clamped by a clamping mechanism, and then bent using a bending mechanism with rollers at both ends. Although the existing clamping mechanism of the bending machine can move along the track on the upper surface of the frame, the lateral adjustment of the clamping components is generally inconvenient, and many cannot even be adjusted, resulting in poor flexibility. In addition, many clamping blocks are connected to the starting jaws by bolts. If the thickness of the plate is different, the entire clamping block must be replaced, and the position needs to be readjusted, which is inconvenient. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Summary of the Invention

[0004] The purpose of this utility model is to provide a clamping mechanism for a bending machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism for a bending machine, comprising a slide block, a slide plate, a pneumatic gripper, a first reduction motor, and a second reduction motor. The upper surface of the slide block is provided with two first guide rails and a first rack, the first rack being disposed between the two first guide rails. First sliders are provided on both sides of the lower surface of the slide plate, each slider corresponding to and slidably connected to one of the first guide rails. A cylinder seat is provided on the upper surface of the slide plate, and a support plate is mounted on the upper surface of the cylinder seat via several columns. The upper surface of the cylinder seat is located on the support plate. Below the slide is a pneumatic gripper. The piston rod of the pneumatic gripper faces to both sides and is connected to a connecting plate. Several guide rods are movably connected to the upper end of the connecting plate. A clamping plate is connected to the inner side of the guide rod. A spring is sleeved on the outside of the guide rod. The two ends of the spring are respectively supported between the connecting plate and the clamping plate. A clamping block is installed on the inner side of the clamping plate by bolts. A boss is provided on the upper part of the inner surface of the clamping block. A first reduction motor is also provided on the upper surface of the slide. The output shaft of the first reduction motor passes through the slide and is equipped with a first gear. The first gear meshes with a first rack. The lower surface of the slide is provided with two second sliders at both ends, and the upper surface of the slide is also provided with a second reduction motor. The output shaft of the second reduction motor passes through the slide and is equipped with a second gear. The slide is slidably engaged with the second guide rail through the second slider. The second guide rail is provided on the upper surface of the frame. The upper part of the frame is also provided with a second rack, and the second gear meshes with the second rack.

[0006] Preferably, the bending machine clamping mechanism provided by this utility model has a first drag chain mounting bracket provided on one side of the upper surface of the slide.

[0007] Preferably, the bending machine clamping mechanism provided by this utility model includes a second drag chain mounting bracket on the upper surface of the slide plate.

[0008] Preferably, in the bending machine clamping mechanism provided by this utility model, the outer end of the guide rod is provided with a limiting head.

[0009] Compared with the prior art, the beneficial effects of this utility model are: (1) The first gear is driven to rotate by the first gear reduction motor. Through the cooperation of the first gear and the first rack, the slide plate moves laterally along the first guide rail. The position of the slide plate can be adjusted according to the dropping position of the long strip workpiece, which greatly improves the flexibility. The second gear is driven to rotate by the second gear reduction motor. Through the cooperation of the second gear and the second rack on the upper part of the frame, the slide block moves along the second guide rail on the upper surface of the frame. Thus, the clamping mechanisms can be adjusted according to the long strip workpieces of different lengths, which greatly improves the flexibility and applicability.

[0010] (2) The clamping block is provided with a boss to ensure that the long strip-shaped workpiece will not tilt after being clamped, and to ensure the stability of the workpiece during bending. At the same time, the clamping block is connected to the clamping plate by bolts and is a detachable structure, so that only the clamping block needs to be replaced according to the long strip-shaped workpiece of different thicknesses. After replacing the clamping block, the position is basically different, which greatly improves the convenience and further enhances the applicability. Attached Figure Description

The upper surface of the cylinder seat 9, below the support plate 11, is provided with a pneumatic gripper 3, the piston rod of which faces two... A connecting plate 12 is connected to the side, and several guide rods 13 are movably connected to the upper end of the connecting plate 12. The outer end of the guide rod 13 is provided with a limit head 26 to prevent the guide rod 13 from detaching from the connecting plate 12. A clamping plate 14 is connected to the inner side of the guide rod 13, and a spring 15 is sleeved on the outside of the guide rod 13. The two ends of the spring 15 are respectively supported between the connecting plate 12 and the clamping plate 14. A clamping block 16 is provided on the inner side of the clamping plate 14 by bolts. A boss 17 is provided on the upper part of the inner surface of the clamping block 16. A first reduction motor 4 is also provided on the upper surface of the slide plate 2. The output shaft of the first reduction motor 4 passes through the slide plate 2 and is equipped with a first gear 18. The first gear 18 meshes with the first rack 7. The slide block 1 has two ends of the lower surface of the slide block 1 with second sliders 19. The upper surface of the slide block 1 is also provided with a second reduction motor 5. The output shaft of the second reduction motor 5 passes through the slide block 1 and is equipped with a second gear 20. The slide block 1 is slidably engaged with the second guide rail 21 through the second sliders 19. The second guide rail 21 is provided on the upper surface of the frame 22. The upper part of the frame 22 is also provided with a second rack 23. The second gear 20 meshes with the second rack 23.

[0015] A first cable chain mounting bracket 24 is provided on one side of the upper surface of the slide block 1 to connect one end of the cable chain to the first cable chain mounting bracket 24. The other end of the cable chain is connected to the upper surface of the frame 22 by bolts.

Through the cooperation of the second gear 20 and the second rack 23 on the upper part of the frame 22, the slide block 1 moves along the second guide rail 21 on the upper surface of the frame 22. This allows the clamping mechanisms to be adjusted according to long strip-shaped workpieces of different lengths, greatly improving flexibility and applicability. The clamping block 16 is provided with a boss 17 to ensure that the long strip-shaped workpiece will not tilt after being clamped, ensuring the stability of the workpiece during bending. At the same time, the clamping block 16 is connected to the clamping plate 14 by bolts, which is a detachable structure. This allows only the clamping block 16 to be replaced according to the long strip-shaped workpiece of different thicknesses. After replacing the clamping block 16, the position does not need to be readjusted, greatly improving convenience and further enhancing applicability.
