Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a traction device for pipe production. Background Technology

[0002] In modern pipe production lines, the traction device is an indispensable key piece of equipment. It is typically located downstream of the extrusion or welding forming unit, and its main function is to apply a stable and continuous axial traction force to the freshly formed but not yet fully cooled and solidified pipe, ensuring production speed and dimensional accuracy. The performance of the traction device directly affects the wall thickness uniformity, straightness, and surface quality of the final pipe product.

[0003] However, in actual production, to meet diverse market demands, manufacturers often need to switch between different pipe specifications. Existing traction devices often exhibit poor adaptability when faced with this requirement. When changing production specifications, operators typically need to perform tedious manual adjustments to the clamping mechanism or guide rollers of the traction device, which is not only time-consuming and labor-intensive but also significantly reduces the overall efficiency of the production line.

[0004] More importantly, many existing traction devices do not handle the initial guidance and centering of the pipes effectively. If the pipes are not effectively aligned with the central axis before entering the main traction mechanism, they will wobble or sway under the traction force. This unstable traction state not only affects the coaxiality and straightness of the pipes, but may also cause scratches or indentations on the pipe surface due to uneven clamping force, thereby reducing the product qualification rate.

[0005] Therefore, this utility model proposes a traction device for pipe production to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of traction devices used for pipe production, such as cumbersome and time-consuming adjustments when changing pipes of different specifications, and poor guiding and centering effect of the pipe during traction, resulting in unstable operation, this utility model aims to provide a traction device for pipe production with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a traction device for pipe production, comprising: a support column, a conveyor frame fixed on the support column, a conveyor belt running on the conveyor frame, a wheel roller support fixed to the outside of the conveyor frame, a wheel roller support beam connected to the wheel roller support, and a sliding wheel roller rotatably connected to the wheel roller support beam; a fixed plate fixedly connected to the rear side of the support column, an adjustment platform movably connected to the top of the fixed plate, a side plate fixed to the adjustment platform, and a chuck fixed to the side plate.

[0008] The chuck has a ring of evenly distributed linkage plates inside, and pulleys are rotatably connected to the inner side of the linkage plates. A spring is elastically connected between the linkage plates and the inner wall of the chuck.

[0009] Furthermore, the sliding roller and the conveyor belt are arranged in a vertically opposite manner to define a traction channel for pulling the pipe, and the chuck is positioned at the entrance of the traction channel. Through the structural combination of the above-mentioned components, a complete traction device integrating adjustable guiding and centering functions is formed.

[0010] Preferably, the traction device for pipe production further includes a drive motor and a drive wheel axle. The drive motor is fixed on the support column, and its output end is connected to the drive wheel axle for transmission. The conveyor belt is sleeved on the drive wheel axle to provide power for traction.

[0011] Preferably, the connection between the adjustment platform and the fixed plate is a vertical sliding connection to achieve convenient height adjustment.

[0012] Preferably, the spring is a compression spring, with its two ends abutting against the outer wall of the linkage plate and the inner wall of the chuck, respectively.

[0013] Preferably, there are multiple linkage plates, which are equidistantly distributed along the circumference of the chuck to form a uniform circumferential clamping of the pipe.

[0014] Preferably, there are multiple roller supports, which are arranged in an array along the length of the conveyor frame to provide stable support for the upper sliding rollers.

[0015] Preferably, the wheel roller support beam and the wheel roller support column are connected by bolts, which facilitates assembly and maintenance.

[0016] Preferably, the bottom of the support column is fixedly connected with anti-slip feet to increase the overall stability of the equipment during operation.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting up a liftable adjustment platform and fixing a chuck containing a spring, a linkage plate and a pulley on the adjustment platform, the problems of complex adjustment when adapting to different specifications of pipes in existing traction devices, as well as inaccurate pipe guidance and poor coaxiality during traction are solved. The technical effect of being able to quickly adapt to different pipe diameters and accurately and automatically center the pipe is achieved, thereby significantly improving traction stability and product quality.

[0018] 2. In this utility model, by setting a spring-driven linkage plate inside the chuck, and rotatably connecting a pulley on the inner side of the linkage plate, the problem of surface scratches or running jams that may occur when the pipe enters the traction mechanism due to excessive frictional resistance is solved. The technical effect of using the rolling friction of the pulley to replace the sliding friction is achieved, making the pipe introduction process smoother and the resistance smaller, effectively protecting the surface of the pipe.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a traction device for pipe production, which aims to solve the problems of poor adaptability when traction of pipes of different specifications and unstable operation caused by low coaxiality of pipes during traction.

[0023] like Figure 1As shown, the traction device for pipe production includes a support column 1 that serves as the base for the overall installation of the equipment. Anti-slip foot supports 2 are fixedly connected to the bottom of the support column 1. A conveyor frame 6 is fixed on the support column 1. A conveyor belt 4 runs on the conveyor frame 6. Multiple wheel roller supports 11 are fixedly connected to the outside of the conveyor frame 6. The multiple wheel roller supports 11 are arranged in an array along the length direction of the conveyor frame 6. Wheel roller support beams 13 are connected to the wheel roller supports 11. Sliding wheel rollers 12 are rotatably connected to the wheel roller support beams 13. The sliding wheel rollers 12 are located above the conveyor belt 4, and the sliding wheel rollers 12 and the conveyor belt 4 together define a traction channel for traction of pipes.

[0024] like Figure 1 and Figure 4 As shown, the core innovation of this traction device for pipe production lies in its guiding and centering assembly. This assembly includes a fixed plate 7 fixedly connected to the rear side of the support column 1. An adjustment platform 8 is vertically connected to the top of the fixed plate 7. A side plate 9 is fixedly connected to the adjustment platform 8. A chuck 10 is fixed on the side plate 9. The chuck 10 is positioned directly opposite the entrance of the traction channel and is used to guide and center the pipe before it enters the traction channel.

[0025] Specifically, such as Figure 4 As shown, the internal structure of the chuck 10 includes multiple linkage plates 15 evenly distributed in a ring along the circumference of the chuck 10. Each linkage plate 15 has a pulley 16 rotatably connected to its inner side, and a spring 14 is elastically connected between the outer wall of each linkage plate 15 and the inner wall of the chuck 10. The elastic force of the spring 14 pushes the linkage plate 15 to move inward, thereby enabling the multiple pulleys 16 to form an adaptive, encircling, flexible clamping of the pipe passing through the chuck 10.

[0026] To achieve stable traction of the pipe, the traction mechanism and drive mechanism of the traction device used for pipe production have been specifically structurally arranged.

[0027] Please refer to the following carefully. Figure 1 , Figure 2 and Figure 3 The traction and drive structure will be described in detail below: The traction action of the device is completed by the upper sliding roller 12 and the lower conveyor belt 4 working together. Specifically, the bottom of multiple roller support columns 11 is fixed to the outer surface of the conveyor frame 6 by welding or bolting, and the top of the roller support column 11 is used to support the roller support beam 13. The roller support beam 13 is fixed to the roller support column 11 by bolts, thus forming a stable upper frame. The sliding roller 12 is rotatably connected to the roller support beam 13 through bearings, so that the sliding roller 12 can rotate freely when the pipe passes through, reducing frictional resistance.

[0028] Meanwhile, the driving power of the device comes from a drive motor 5 fixedly connected to the bottom of the support column 1. The output end of the drive motor 5 is connected to the input end of a drive wheel shaft 3. The drive wheel shaft 3 is rotatably connected to the support column 1 through a bearing seat. The conveyor belt 4, as a flexible traction component, has a ring structure and is sleeved on the drive wheel shaft 3 and the driven wheel shaft at the far end of the conveyor frame 6. The two sides of the conveyor frame 6 limit the edge of the conveyor belt 4 to ensure that the conveyor belt 4 will not deviate laterally when running at high speed. This traction channel structure formed by the upper and lower cooperation of the conveyor belt 4 and the sliding wheel 12 ensures the stable application of traction force by increasing the contact area with the pipe.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, in order to flexibly adapt to pipes of different diameters, an adjustable connection is realized between the adjusting platform 8 and the fixed plate 7. Specifically, the adjusting platform 8 is slidably connected to the fixed plate 7 in the vertical direction. For example, a vertical guide groove is provided on the surface of the fixed plate 7, and a slider that cooperates with the guide groove is provided on the corresponding side of the adjusting platform 8, so that the adjusting platform 8 can slide smoothly up and down and be fixed at any desired height position by a locking mechanism.

[0030] As another preferred embodiment, in order to provide a reliable and stable centripetal elastic force to the linkage plate 15, the spring 14 is specifically a compression spring 14. The spring 14 is installed between the outer side wall of the linkage plate 15 and the inner side wall of the chuck 10, with its two ends abutting against the linkage plate 15 and the chuck 10 respectively. In its natural state, the spring 14 is in a pre-compressed state, thereby applying a continuous, center-directed thrust to the linkage plate 15.

[0031] In another preferred embodiment, in order to achieve uniform clamping and guiding of the pipe in the circumference and ensure the stability of the centering effect, multiple linkage plates 15 are provided. These linkage plates 15 are equidistantly distributed along the inner circumference of the chuck 10. This layout allows multiple pulleys 16 connected to the linkage plates 15 to contact the outer wall of the pipe from multiple directions at the same time, forming a stable multi-point support and guiding structure.

[0032] Working principle: Before the pipe traction operation, the vertical height of the adjusting platform 8 on the fixed plate 7 can be adjusted according to the diameter of the pipe to be traction. The lifting and lowering of the adjusting platform 8 drives the side plate 9 and the chuck 10 fixed on it to move synchronously, so that the center of the chuck 10 is aligned with the central axis of the traction channel formed by the conveyor belt 4 and the sliding wheel 12, so as to complete the rapid adaptation of pipes of different specifications.

[0033] When traction begins, the drive motor 5 starts, and its power is transmitted to the conveyor belt 4 through the drive wheel axle 3, causing the conveyor belt 4 to start running continuously. At this time, the end of the pipe is fed into the chuck 10, and the outer wall of the pipe first contacts the pulley 16 on the inner side of the linkage plate 15. Since the spring 14 always applies an inward elastic thrust to the linkage plate 15, the multiple pulleys 16 will form an adaptive, encircling flexible clamp on the pipe from different directions. This structure not only enables the pipe to pass smoothly through the chuck 10, but more importantly, it can accurately guide it to the center of the traction channel, ensuring the coaxiality and stability of the subsequent traction process.

[0034] After being centered by the chuck 10, the pipe enters the traction channel and is clamped between the lower conveyor belt 4 and the upper sliding roller 12. The running conveyor belt 4 applies a stable and continuous traction force to the pipe through the friction between it and the outer wall of the pipe, pulling the pipe forward smoothly. The entire device operates under the stable frame formed by the support column 1 and the anti-slip foot support 2. Through the synergistic effect of the above-mentioned guiding centering and traction mechanism, this utility model solves the problems of poor adaptability and low traction stability of the traction device in the prior art, and realizes efficient and precise traction of the pipe.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
