Description

Technical Field

[0001] This utility model relates to a pipe rounding device. Background Technology

[0002] Currently, large-diameter plastic pipes are widely used in municipal water supply and drainage, industrial pipelines, and other fields due to their excellent corrosion resistance, ease of construction, and economy. However, during the extrusion production of plastic pipes, the large diameter and relatively thin wall of the pipes make them susceptible to deformation under gravity during the cooling and molding process of the molten plastic. This deformation mainly manifests as insufficient roundness of the pipe cross-section, i.e., an "ellipticization" phenomenon, resulting in substandard geometric dimensional accuracy of the finished pipes, affecting their connection sealing performance and service life.

[0003] A search of existing technologies revealed a Chinese patent (CN217553112U) disclosing a pipe rounding device. This patent uses a drive mechanism that adjusts a left and right rounding assembly to correct the pipe. However, during use, it was found that, especially when rounding large-diameter pipes, the device requires significant pressure to ensure the stability of the left and right rounding assemblies, potentially leading to an unstable rounding process. Furthermore, the device lacks a clear dimension display, making it difficult for operators to accurately assess the effectiveness of the rounding adjustments. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a pipe rounding device that can apply stable and controllable pressure to the pipe, ensuring a smooth and reliable rounding process, while allowing operators to intuitively obtain the specific dimensions to be adjusted, thereby improving the rounding accuracy and work efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a pipe rounding device, comprising:

[0006] The frame body is provided with a conveying channel;

[0007] A set of transverse guide rail assemblies, the transverse guide rail assemblies being installed on the upper and lower sides of the frame body;

[0008] A set of vertical support frames, the upper and lower ends of which are slidably connected to the horizontal guide rail assembly, and the vertical support frames are located on both sides of the conveying channel;

[0009] A set of rounding rollers, each of which is mounted on a corresponding vertical support frame;

[0010] Two sets of drive mechanisms are respectively located on the front and rear sides of the frame body. Each set of drive mechanisms includes two drive units. Each drive unit has a fixed end and a telescopic end. The fixed ends of the two drive units located on the front side of the frame body are respectively hinged to the upper and lower parts of the front side of the frame body, and their telescopic ends are respectively hinged to the upper and lower parts of the vertical support frame located on the left side of the conveying channel in the conveying direction. The fixed ends of the two drive units located on the rear side of the frame body are respectively hinged to the upper and lower parts of the rear side of the frame body, and their telescopic ends are respectively hinged to the upper and lower parts of the vertical support frame located on the right side of the conveying channel in the conveying direction.

[0011] At least one scale display ruler is mounted on a crossbeam on the lower side of the frame body, and the scale display ruler is provided with scale markings that increase from the center to both sides.

[0012] Furthermore, a specific structure for a rounding idler is provided, the rounding idler including a pair of idler brackets and an idler assembly, the idler brackets being detachably mounted on the vertical support frame in the vertical direction by fasteners, and the idler assembly being rotatably mounted on the idler brackets.

[0013] Furthermore, the vertical support frame is provided with multiple adjustment mounting holes spaced apart along the vertical direction;

[0014] The idler bracket is adapted to adjust the height of the idler assembly by connecting the corresponding adjustment mounting holes with fasteners.

[0015] Furthermore, the idler assembly includes an idler shaft and an idler body sleeved on the outer periphery of the idler shaft, wherein the outer surface of the idler body is formed with an arc-shaped groove that mates with the pipe.

[0016] Furthermore, the bottom of the frame body is provided with multiple foot fixing seats, and the foot fixing seats are provided with fixing holes.

[0017] Furthermore, a specific structure of a drive mechanism is provided, the drive mechanism including a hydraulic station and a plurality of hydraulic drive telescopic components, the hydraulic station being fixedly installed on the frame body, the hydraulic station being connected to the hydraulic drive telescopic components via oil pipes, the cylinder of the hydraulic drive telescopic component being hinged to the frame body, and the piston rod of the hydraulic drive telescopic component being hinged to the corresponding vertical support frame.

[0018] Furthermore, the transverse guide rail assembly is a circular guide rail.

[0019] By adopting the above technical solution, this utility model has the following beneficial effects:

[0020] This invention is primarily applicable to the roundness correction of large pipes. The specific operation process is as follows: Before the pipe enters the conveying channel through the vacuum chamber, the operator, based on the dimensions of the pipe to be processed, observes the reading on the scale display below the machine frame and adjusts the drive mechanism to bring the vertical support frame to the required position. After reaching the designated position, a roundness measuring instrument is used to inspect the pipe to ensure that its roundness meets the processing requirements. If discrepancies exist, the operator fine-tunes the position of the roundness correction rollers based on the measurement results to ensure accuracy. Finally, the pipe continues to be conveyed through the roundness correction device. During this process, a hydraulic station drives the hydraulically operated telescopic components to ensure that the roundness correction rollers apply stable pressure to the pipe, thereby completing the roundness correction.

[0021] Furthermore, the rounding idler consists of an idler bracket and an idler assembly, which can be adjusted according to different pipe diameters and shapes. The height and position of the idler bracket can be easily adjusted via the adjustment mounting holes on the vertical support frame, thereby meeting the processing requirements of pipes with different output heights and idler assemblies of different lengths.

[0022] In summary, this utility model ensures the pressure of the rounding roller on the pipe through hydraulic drive, ensures the accuracy of pipe rounding through the upper and lower drive mechanisms, and improves production efficiency by setting two sets at the front and rear of the frame body.

[0025] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] like Figure 1-2 As shown, a pipe rounding device includes:

[0027] The frame body 1 is provided with a conveying channel;

[0028] A set of transverse guide rail assemblies 2 are installed on the upper and lower sides of the frame body 1;

[0029] A set of vertical support frames 3, the upper and lower ends of which are slidably connected to the horizontal guide rail assembly 2, and the vertical support frames 3 are located on both sides of the conveying channel;

[0030] A set of rounding rollers 4 are installed on the corresponding vertical support frame 3;

[0031] Two sets of drive mechanisms 5 are respectively set on the front and rear sides of the frame body 1. Each set of drive mechanisms 5 includes two drive units. Each drive unit has a fixed end and a telescopic end. The fixed ends of the two drive units located on the front side of the frame body 1 are respectively hinged to the upper and lower parts of the front side of the frame body 1, and their telescopic ends are respectively hinged to the upper and lower parts of the vertical support frame 3 located on the left side of the conveying channel in the conveying direction. The fixed ends of the two drive units located on the rear side of the frame body 1 are respectively hinged to the upper and lower parts of the rear side of the frame body 1, and their telescopic ends are respectively hinged to the upper and lower parts of the vertical support frame 3 located on the right side of the conveying channel in the conveying direction.

[0032] Two scale display rulers 6 are mounted on the crossbeam on the lower side of the frame body 1. The scale display rulers 6 are provided with scale markings that increase from the center to both sides.

[0033] In this embodiment, as Figure 1 As shown, this embodiment is mainly applicable to the rounding process of large pipes. The specific operation process is as follows: Before the pipe enters the conveying channel through the vacuum chamber, the operator, according to the size specifications of the pipe to be processed, observes the reading on the scale display 6 located below the machine frame 1 and adjusts the drive mechanism 5 to bring the vertical support frame 3 to the required designated position. After reaching the designated position, a roundness measuring instrument is used to inspect the pipe to ensure that the roundness of the pipe meets the processing requirements. If there are discrepancies, the operator then fine-tunes the position of the rounding roller 4 according to the measurement results to ensure the accuracy of the rounding. Finally, the pipe continues to be conveyed through the rounding device. During this process, the hydraulic station 51 drives the hydraulically driven telescopic component to ensure that the rounding roller 4 applies stable pressure to the pipe, thereby completing the rounding of the pipe. The upper and lower drive mechanisms 5 ensure the accuracy of the pipe rounding, and the drive mechanisms 5 are also set on the front and rear sides of the machine frame 1 to improve the rounding adjustment efficiency. Two scale display 6s are respectively installed on the front and rear sides of the crossbeam below the machine frame 1.

[0034] Specifically, such as Figure 1-2 As shown, the rounding roller 4 includes a pair of roller brackets 41 and roller assembly 42. The roller brackets 41 are detachably mounted on the vertical support frame 3 in the vertical direction by fasteners, and the roller assembly 42 is rotatably mounted on the roller brackets 41.

[0035] Specifically, such as Figure 1-2 As shown, the vertical support frame 3 has multiple adjustment mounting holes 311 spaced apart along the vertical direction;

[0036] The idler bracket 41 is adapted to adjust the height of the idler assembly 42 by connecting corresponding adjustment mounting holes 311 via fasteners.

[0037] Specifically, such as Figure 1 As shown, the idler assembly 42 includes an idler shaft and an idler body sleeved on the outer periphery of the idler shaft. The outer surface of the idler body is formed with an arc-shaped groove that matches the pipe.

[0038] In this embodiment, as Figure 1-2 As shown, the design of the idler bracket 41 and idler assembly 42 allows the rounding idler 4 to adapt to pipes of different diameters. The idler bracket 41 is connected to the adjustment mounting hole 311 on the vertical support frame 3 via fasteners, allowing the operator to adjust the installation height of the idler assembly 42 according to the pipe size. When different specifications of pipes need to be processed, only the corresponding idler assembly 42 needs to be replaced. The adjustment mounting hole 311 on the vertical support frame 3 allows for the use of idler assemblies 42 of different lengths through different arrangements and combinations.

[0039] Specifically, such as Figure 1 As shown, the bottom of the frame body 1 is provided with four foot fixing seats 11, and the foot fixing seats 11 are provided with fixing holes.

[0040] In this embodiment, as Figure 1 As shown, the fixing holes are used to securely install the device on the ground using anchor bolts. During actual installation, the anchor base 11 can be used with shims for leveling, solving the problem of uneven ground.

[0041] Specifically, such as Figure 1 As shown,

[0042] The drive mechanism 5 includes a hydraulic station 51 and multiple hydraulic drive telescopic components. The hydraulic station 51 is fixedly installed on the frame body 1. The hydraulic station 51 is connected to the hydraulic drive telescopic components through oil pipes. The cylinder of the hydraulic drive telescopic component is hinged to the frame body 1, and the piston rod of the hydraulic drive telescopic component is hinged to the corresponding vertical support frame 3.

[0043] In this embodiment, as Figure 1 As shown, the drive mechanism 5 adopts a hydraulic drive method. In actual use, the operator adjusts the output parameters of the hydraulic drive telescopic component through the hydraulic station 51 to generate a suitable thrust and complete the pipe rounding operation.

[0044] Specifically, such as Figure 1 As shown, the horizontal guide rail assembly 2 is a circular guide rail.

[0045] In this embodiment, as Figure 1 As shown, the horizontal guide rail assembly 2 adopts a circular guide rail design to provide guidance and support for the horizontal movement of the vertical support frame 3. This ensures that the vertical support frame 3 moves smoothly and steadily during horizontal movement.

[0046] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
