Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a mechanical manufacturing traction device. Background Technology

[0002] When pipes are bent or cut, a traction device, such as a traction machine, is usually needed to transport the pipes into the bending or cutting machine. The traction device is usually equipped with a correction mechanism to adjust the position of the pipes and prevent incorrect bending or cutting positions due to pipe position deviation during processing.

[0003] Chinese utility model patent discloses a mechanical manufacturing traction device (publication number: CN220466495U). When tractioning a pipe, the device uses two sets of limiting plates in conjunction with a dual-axis motor to achieve deviation correction. Through the action of torsion springs and guide plates, the pipe is guided into the space between the two limiting plates, thereby preventing the pipe from hitting the limiting plates. To a certain extent, this increases the efficiency of deviation correction and ensures the processing effect of the pipe. However, because the opening of the guide plate facing the pipe entry side is large, and the connection between the guide plate and the limiting plate is made by a connecting block and a fixed shaft, there will be a large gap between the guide plate and the limiting plate in the normal state. This gap is easily damaged by the pipe impact. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mechanical manufacturing traction device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mechanical manufacturing traction device includes a plate body, which includes two limiting plates. The two limiting plates are fixed parallel to each other on both sides of a receiving plate. A movable tube is fixed to one end of the limiting plate, and a threaded rod is movably passed through the movable tube. A limiting ring is fixed on the limiting plate, and a plurality of threaded holes are opened on the limiting ring. A bolt is threaded into one of the threaded holes. A fixing ring is also fixed on the limiting plate, and the fixing ring coincides with the central axis of the limiting ring. A guide component is rotatably connected to the fixing ring through a bearing.

[0007] The guiding assembly includes a cylinder that mates with the bearing. A guide plate is fixed to one side of the cylinder. A notch is provided below the guide plate on the side near the cylinder. A torsion spring is movably installed inside the cylinder. One end of the torsion spring is fixed to the inner wall of the cylinder, and the other end of the torsion spring is fixed to a rod. The rod moves through the torsion spring and is fixed to a limiting plate. A mounting hole is also provided on one side of the cylinder. A limiting rod is fitted into the mounting hole. The limiting rod and the bolt are used in conjunction with each other.

[0008] Preferably, two fixing nuts are threaded onto the threaded rod, and the two fixing nuts are respectively located at the upper and lower ends of the moving tube.

[0009] Preferably, the upper and lower ends of the threaded rod are movably mounted on two fixed ears, which are respectively fixed on the second conveyor and the first conveyor.

[0010] Preferably, the second conveyor is fixed to the base box by a bracket, and the first conveyor is fixed to the base box.

[0011] Preferably, the first conveyor and the second conveyor are arranged symmetrically to each other, and the conveyor belts of the first conveyor and the second conveyor face each other.

[0012] Preferably, the two guide components are arranged symmetrically to each other, and the guide plate faces the central axis of the receiving plate.

[0013] Preferably, when the guide assembly is in its natural state, the limiting rod overlaps on the side of the bolt facing the other guide assembly.

[0014] This utility model has the following beneficial effects:

[0015] 1. The guide component of this utility model can guide the pipe to a suitable position and prevent the pipe from deviating. Furthermore, since the guide component uses a single guide plate as the guide structure, it can prevent the pipe from colliding with other components, thereby reducing the possibility of damage during use.

[0016] 2. This utility model can adjust the size of the opening between the two guide plates by adjusting the installation position of the bolts, thus making it suitable for pipes of different diameters and having strong applicability. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A mechanical manufacturing traction device includes a plate body 1, which includes two limiting plates 101. The two limiting plates 101 are fixed in parallel on both sides of a receiving plate 102. After the pipe enters the traction device, it is supported by the receiving plate 102. The two limiting plates 101 are the edges of the plate body 1.

[0025] One end of the limiting plate 101 is fixed with a movable tube 103. A threaded rod 104 is movably inserted through the movable tube 103. Two fixing nuts 105 are threaded on the threaded rod 104. The two fixing nuts 105 are respectively set at the upper and lower ends of the movable tube 103. With this arrangement, the position of the plate 1 can be adjusted.

[0026] A limiting ring 2 is fixed on the limiting plate 101. The limiting ring 2 has several threaded holes 201. One of the threaded holes 201 is threaded with a bolt 202. By adjusting the position of the bolt 202, the opening between the two guide plates 502 can be adjusted.

[0027] A fixing ring 3 is also fixed on the limiting plate 101. The fixing ring 3 coincides with the central axis of the limiting ring 2. The guide component 5 is rotatably connected inside the fixing ring 3 through the bearing 4. This arrangement allows the guide component 5 to rotate.

[0028] Two guide components 5 are symmetrically arranged between each other. Each guide component 5 includes a cylinder 501 that cooperates with the bearing 4. A guide plate 502 is fixed on one side of the cylinder 501. The guide plate 502 faces the central axis of the receiving plate 102. By setting the guide plate 502, the pipe can be corrected. Under the guidance of the guide plate 502, the pipe moves towards the opening between the two guide plates 502.

[0029] A notch 503 is provided below the guide plate 502 on the side near the cylinder 501. The notch 503 provides sufficient space for the guide plate 502 to rotate when it comes into contact with the limiting plate 101.

[0030] A torsion spring 505 is movably installed inside the cylinder 501. One end of the torsion spring 505 is fixed to the inner wall of the cylinder 501, and the other end of the torsion spring 505 is fixed to the rod 506. The rod 506 movably passes through the torsion spring 505 and is fixed to the limiting plate 101. Through the action of the torsion spring 505 and the rod 506, the guide plate 502 can be quickly reset when it is impacted by the pipe, and at the same time, it has a certain buffering effect, thereby protecting the pipe.

[0031] A mounting hole 504 is also provided on one side of the cylinder 501. A limiting rod 6 is fitted inside the mounting hole 504. The limiting rod 6 and the bolt 202 cooperate with each other. When the guide component 5 is in the natural state, the limiting rod 6 overlaps on the side of the bolt 202 facing the other guide component 5. With this setting, the minimum size of the opening between the two guide plates 502 can be adjusted, so as to be suitable for pipes of different diameters.

[0032] In use, the plate 1 of this invention is moved to the outlet of the upstream equipment of the pipe processing production line. The position of the bolt 202 is adjusted according to the size of the pipe being processed, thereby adjusting the minimum distance between the two guide plates 502. When the pipe enters the plate 1, it is corrected by the two guide components 5. When the pipe hits the guide plate 502, the guide plate 502 will rotate slightly. Under the action of the torsion spring 505, the guide plate 502 will immediately return to its original position, thereby guiding the pipe to the appropriate position and preventing deviation. Finally, the pipe enters the gap between the first conveyor 8 and the second conveyor 10, and is traction conveyed under the guidance of the first conveyor 8 and the second conveyor 10.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
