Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, specifically to an anti-deviation device for pipe manufacturing. Background Technology

[0002] Pipes are an indispensable basic material in construction projects, industrial facilities and daily life. They are mainly used to transport fluids (such as water, gas, oil, etc.), protect cables or serve as structural supports. Anti-deviation devices are commonly used equipment in the pipe production process.

[0003] Patent CN216071835U discloses an anti-deviation device for producing plastic pipes. It includes a workbench with multiple anti-deviation structures installed on the upper part of the workbench. Each anti-deviation structure consists of a base plate, a limiting post, a connecting piece, a limiting nut, a first roller, and a second roller. This device prevents wear on the surface of the plastic pipe, which is beneficial for the maintenance of the plastic pipe. It can effectively prevent the plastic pipe from deviating and deforming, reduce the cost of plastic pipe production, and improve the functionality of the anti-deviation device.

[0004] However, the length of the first roller and the angle between the first and second rollers are fixed in this device. This makes it difficult to ensure that the second roller can limit and support the pipe when the pipe is thin, while the pipe may be directly supported and limited by the second rollers on both sides when the pipe is thick, thus failing to fit with the first roller and leaving it suspended in the air, which affects the pipe's positioning. To address this, a pipe production anti-deviation device is proposed to solve the problem that existing anti-deviation devices are difficult to stably limit and move according to the pipe groove size.

[0015] (III) Beneficial Effects

[0016] 1. This anti-deviation device for pipe production uses a servo motor on a fixed plate to drive a bidirectional lead screw to rotate. Under the action of the movable block in the movable groove, the limiting column in the limiting groove, and the rotating shaft, the angle of the rotating arm in the rotating groove is adjusted. For small-sized pipes, the second roller deflects inward, and vice versa. The second roller is used to limit and support the outside of the pipe, improving the applicability of this device and solving the problem that existing anti-deviation devices are difficult to stably limit and move according to the size of the pipe groove.

[0017] 2. The anti-deviation device for pipe production, after the pipe is limited and supported by the first and second rollers, drives the lifting block to move down by the electric push rod, which in turn drives the adjusting frame in the fixed frame, together with the limiting roller, to move down to fit with the pipe but not squeeze it. This limits the pipe from the top, further preventing deviation during pipe production, thus improving the stability and safety of the pipe production process. 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. 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.

[0024] Example: Please refer to Figure 1-4A device for preventing deviation in pipe production includes a workbench 1. A first roller 2 is provided on the top of the workbench 1. A rotating groove 3 is symmetrically provided on the top of the workbench 1. A rotating arm 4 is provided in the inner cavity of the rotating groove 3. A second roller 5 is provided on the opposite end face of the rotating arm 4. The rotating arm 4 is set in the inner cavity of the rotating groove 3 through a rotating shaft 6. A movable groove 7 is provided at the bottom of the rotating arm 4. A movable block 8 is movably provided in the inner cavity of the movable groove 7. Limiting grooves 9 are provided on both sides of the rotating arm 4. Limiting posts 10 are provided in the inner cavity of the limiting grooves 9. Fixed plates 11 are symmetrically and fixedly connected to the bottom of the workbench 1. A bidirectional lead screw 12 is provided between the front and rear fixed plates 11. A servo motor 13 is fixedly connected to one end of the rear fixed plate 11. A sprocket 14 is rotatably connected to one end of each fixed plate 11. The sprocket 14 is connected by a chain 15. A stabilizing mechanism 16 is provided on the top of the workbench 1. An adjusting mechanism 17 is provided on one side of the workbench 1.

[0025] Furthermore, the inner cavities of the limiting groove 9 and the movable groove 7 are interconnected, and the limiting post 10 passes through the limiting groove 9 and is fixedly connected to the movable block 8.

[0026] Furthermore, the bidirectional lead screw 12 passes through the movable block 8 and the two are threadedly connected. The bidirectional lead screw 12 passes through the fixed plate 11 and is fixedly connected to the output shaft of the servo motor 13. The bidirectional lead screw 12 passes through the fixed plate 11 and is fixedly connected to the sprocket 14.

[0027] Furthermore, the stabilizing mechanism 16 includes a fixed frame 161 fixedly connected to the top of the workbench 1. An adjusting frame 162 is slidably arranged in the inner cavity of the fixed frame 161. A limiting roller 163 is rotatably connected in the inner cavity of the adjusting frame 162. The limiting roller 163 is composed of two frustums.

[0028] Furthermore, lifting blocks 164 are slidably installed through both ends of the fixed frame 161. An electric push rod 165 is fixedly connected to the bottom of the lifting block 164. The bottom of the electric push rod 165 is fixedly connected to the worktable 1. The lifting block 164 is fixedly connected to the adjusting frame 162. After the pipe is limited and supported by the first roller 2 and the second roller 5, the lifting block 164 is moved down by the electric push rod 165. This causes the adjusting frame 162 in the fixed frame 161, together with the limiting roller 163, to move down to fit the pipe but not squeeze it. This limits the pipe from the top, further preventing deviation during the pipe production process, thus improving the stability and safety of the pipe production process.

[0029] Furthermore, the adjustment mechanism 17 includes an adjustment platform 171 disposed on one side of the workbench 1. The adjustment platform 171 is symmetrically connected to a limit plate 172 on the side facing the workbench 1. The limit plate 172 passes through the workbench 1 and the two are slidably connected.

The bolts 174 penetrate into the inner wall of the limiting plate 172 and the two are threaded together. Rollers 175 are provided at the bottom of the adjusting table 171. When the pipe is long, according to the pipe processing requirements, the adjusting table 171 is moved to the right away from the workbench 1 under the action of the limiting plate 172 and the rollers 175. The anti-detachment grooves 173 are used to improve the stability of the adjusting table 171 during the movement. After the adjusting table 171 is adjusted to the appropriate position, the bolts 174 are tightened to limit the adjusting table 171, increasing the length of the workbench 1 and further improving the practicality and applicability of this anti-deviation device for pipe production.

[0031] Working principle: When using this anti-deviation device for pipe production, the pipe to be processed is placed on the first roller 2 at the top of the workbench 1. The servo motor 13 on the fixed plate 11 drives the bidirectional lead screw 12 to rotate. Under the action of the movable block 8 in the movable groove 7, the limiting column 10 in the limiting groove 9, and the rotating shaft 6, the angle of the rotating arm 4 in the rotating groove 3 is adjusted. For small-sized pipes, the second roller 5 deflects inward, and vice versa. The second roller 5 is used to limit and support the pipe externally, which improves the applicability of this device and solves the problem that existing anti-deviation devices are difficult to stably limit and move according to the size of the pipe groove.
