Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, specifically to a clamping mechanism and a pipe bending machine that are adapted to different specifications of steel pipe diameters. Background Technology

[0002] A pipe bending machine is an industrial device used to bend metal pipes (such as steel pipes, copper pipes, aluminum pipes) or plastic pipes into specific angles. It is widely used in automobile manufacturing, aerospace, furniture, building pipelines and other fields. When bending steel pipes, a clamping mechanism is required to clamp and adjust the pipes.

[0003] Existing pipe bending machines require a clamping mechanism to position and clamp the steel pipe during use, followed by a bending mechanism to bend the pipe to achieve a suitable angle. The clamping mechanism needs to limit the bending adjustment within a suitable range. However, existing pipe clamping mechanisms are difficult to position, resulting in a limited range of adjustable pipe diameters and hindering universal adjustment, thus affecting the applicability of the device. Therefore, optimization and improvement are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping mechanism and a pipe bending machine that are compatible with different specifications of steel pipe diameters, so as to solve the problem mentioned in the background art that the clamping mechanism of the pipe bending machine is difficult to process steel pipe workpieces of different diameters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism adaptable to steel pipes of different diameters, comprising: a support frame, one end of which is connected to an installation plate, and an adjustment frame at the top of the support frame; and an adaptation adjustment component and a clamping replacement component. The adaptation adjustment component includes a rotating screw disposed inside the adjustment frame, a movable plate at the bottom of the rotating screw, and guide elastic rods at the four corners of the top of the movable plate. The adaptation adjustment component is used for clamping and positioning steel pipes of different diameters. The clamping replacement component includes an installation rod disposed inside the installation plate, one end of which is connected to a clamping module. A positioning block is disposed inside the clamping module. The clamping replacement component is used for replacing the clamping module with different specifications.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] like Figure 1 - Figure 4 As shown, this application provides a clamping mechanism adaptable to steel pipes of different diameters, including: a support frame 1, one end of which is connected to a mounting plate 2, and an adjustment frame 3 is provided at the top of the support frame 1; the adaptation adjustment component includes a rotating screw 4, which is disposed inside the adjustment frame 3, and a movable plate 5 is provided at the bottom end of the rotating screw 4, with guide elastic rods 7 provided at the four corners of the top of the movable plate 5. The adaptation adjustment component is used for clamping and positioning steel pipes of different diameters; specifically, as shown... Figure 2 and Figure 4 As shown, the bottom end of the movable plate 5 is connected to the rotating shaft frame 6, and the mounting rod 14 is connected to the inner side of the rotating shaft frame 6. The mounting rod 14 is adjusted by the rotation of the rotating shaft frame 6.

[0019] Specifically, such as Figure 2 As shown, a spring is provided on the outer side of the guide elastic rod 7, and a groove is provided on the outer wall of the guide elastic rod 7. The guide elastic rod 7 is used to guide and adjust the up and down movement of the movable plate 5.

[0020] Specifically, such as Figure 2 As shown, telescopic cylinders 8 are installed at the four corners of the top of the adjustment frame 3, and semi-circular locking blocks 9 are provided on the inner side of the telescopic cylinders 8. The telescopic cylinders 8 drive the semi-circular locking blocks 9 to approach the guide elastic rod 7 and lock them in the slots inside the guide elastic rod 7 for stable positioning.

[0021] Specifically, such as Figure 3 As shown, a connector 10 is provided at the top of the rotating screw 4, and a through rod 11 is connected to the inner side of the connector 10. A limit block 12 is connected to the outer side of the through rod 11, and handles 13 are connected to both ends of the through rod 11. The through rod 11 slides and adjusts inside the connector 10, and the limit block 12 limits the movement position. The handles 13 at both ends make it easy to pick up and adjust.

[0022] The clamping replacement assembly includes a mounting rod 14, which is disposed inside the mounting plate 2. One end of the mounting rod 14 is connected to a clamping module 15. A positioning block 18 is disposed inside the clamping module 15. The clamping replacement assembly is used to replace the clamping module 15 with different specifications.

[0023] Specifically, such as Figure 4 As shown, the clamping module 15 has an adapter groove 16 on its outer side, and an insertion groove 17 is connected to the inner side of the adapter groove 16. A positioning block 18 is located inside the insertion groove 17, and a fastening screw 19 is connected to the inner side of the positioning block 18. The mounting rod 14 is inserted into the inner side of the clamping module 15, and then the positioning block 18 is locked in the insertion groove 17. The mounting rod 14 is then positioned by connecting it with the fastening screw 19.

[0024] A pipe bending machine includes a pipe bending machine body, on which a clamping mechanism adapted to different specifications of steel pipe diameters is installed as described above.

[0025] In this embodiment: when adjusting the bending of steel pipes of different diameters, the rotating screw 4 controls the position of the rotating shaft frame 6 and the height of the clamping module 15. After adjustment, the semi-circular locking block 9 is positioned close to the guide elastic rod 7 to improve the stability of the clamping module 15 after movement. When adjusting steel pipes of different diameters, the interchangeability of the clamping module 15 allows for the replacement of different adapter slots 16 to adapt to steel pipes of different diameters for processing.

[0026] The specific solution is as follows: When processing the pipe bending machine, the steel pipe needs to be positioned and clamped first. At this time, the position needs to be adjusted according to the pipe diameter. Rotating the rotating screw 4 controls the lifting of the rotating shaft frame 6. Then, the guide elastic rod 7 is adjusted at the top of the mounting plate 2 to control the height of the clamping module 15. After adjustment, the telescopic cylinder 8 controls the semi-circular locking block 9 to approach the guide elastic rod 7 for positioning, improving the stability of the clamping module 15 after movement. The positions of the upper and lower clamping modules 15 are adjusted to adapt to the pipe diameter of the steel pipe being processed. Then, according to different steel pipe diameters, the clamping modules 15 with different fitting groove diameters 16 need to be adjusted. The fastening screw 19 can be unscrewed to allow the positioning block 18 to be pulled out of the insertion groove 17. Then, the mounting rod 14 and the clamping module 15 are disassembled and removed. Conversely, they can be replaced and installed, which facilitates the adjustment and processing of steel pipes with different diameters.

[0027] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
