Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing jigs, and particularly relates to a jig for bent pipe processing. Background Art

[0002] There are generally two methods for bent pipe processing, namely cold bending processing forming and hot processing forming. For steel pipes with a cross-section greater than or equal to, medium-frequency or high-frequency bending is generally used for rounding, and for steel pipes with a cross-section less than 800MM, mechanical cold bending is used. After bending, there should be no creases or unevenness on the surface of the steel pipe.

[0003] Of course, when bending pipes, pipe clamps are also essential. For example, a fixed jig for bent pipe processing and forming disclosed in a Chinese utility model patent with the patent publication number CN217831587U. This fixed jig is provided with two N-shaped frames, and a set of threaded rods are symmetrically arranged inside the N-shaped frames. Arc-shaped clamping blocks are arranged at the proximal ends of the threaded rods. By rotating the threaded rods, the arc-shaped clamping blocks approach each other to clamp the pipe. Moreover, feeding is realized by arranging a chain, a sprocket and a guide roller below the clamping block.

[0004] However, when the above-mentioned fixed jig is actually used, feeding and clamping cannot be carried out simultaneously. It is also necessary to manually rotate the threaded rod to make the clamping block clamp the pipe. When the pipe is transported to an appropriate position, the feeding device needs to be stopped, and then the threaded rod is rotated to make the clamping block clamp the pipe. After the bent pipe operation, the screw needs to be loosened to release the pipe, and the operation is complicated, resulting in low operation efficiency. Summary of the Utility Model

[0026] In this embodiment, when the motor 600 is started, the motor 600 drives one of the opposite clamping rollers 200 to rotate, and then the self-locking adjustment member 500 is controlled to drive the gear set 300 to rotate. The gear set 300 rotates and drives the support plate 400 to rotate. The support plate 400 drives the opposite clamping rollers 200 to approach or move away until the distance between the clamping rollers 200 is suitable for the pipe material specification to be processed this time. Then the pipe material is fed between the clamping rollers 200 to start the operation. This device can continuously clamp and feed through the clamping rollers 200, without the need to manually adjust the replacement of materials in the clamping area midway, with simple operation and ensuring the operation efficiency.

[0027] In one of the embodiments, please refer to Figures 1 - 2 , two pairs of strip-shaped sliding holes 110 are opened on the top of the plate body 100.

The self-locking adjustment member 500 is arranged on one side of the main gear 310, and the motor 600 is arranged at the bottom of the support plate 400;

[0031] Among them, the center points of the main gear 310 and the three driven gears 320 are distributed in a rectangle;

[0032] In this embodiment, a total of four gears are provided. These four gears are located on different horizontal planes, and the center point's top view connection lines of the four gears can form a rectangle. The main gear 310 among them meshes with the three driven gears 320 in sequence and does not mesh with each other;

[0033] During specific operation, the self-locking adjustment member 500 can drive the main gear 310 to rotate by meshing. The main gear 310 drives one of the driven gears 320 by meshing. This driven gear 320 drives another driven gear 320 by meshing. This other driven gear 320 drives the last driven gear 320, and thus the transmission can be completed.

[0034] In one of the embodiments, please refer to Figures 2 - 3 , the number of support plates 400 is the same as the number of second rotating shafts 330. One end of the support plate 400 is fixedly sleeved on the middle part of the second rotating shaft 330. The other ends of the four support plates 400 are respectively rotatably connected to the bottom of the adjacent first rotating shaft 120;

[0035] In this embodiment, when the main gear 310 and the three driven gears 320 rotate, the support plate 400 can be driven to rotate through the second rotating shaft 330.

[0036] In one of the embodiments, please refer to Figures 2 - 3 , the motors 600 are arranged in pairs, and the motors 600 are fixedly arranged at the bottoms of two support plates 400 that are not in the same group.
