Description

Technical Field

[0001] This utility model belongs to the field of pipe straightening technology, and in particular relates to a pipe straightening device. Background Technology

[0002] In industrial production, especially in metal processing and pipe manufacturing, pipes may bend or deform during production, transportation, or storage, which can affect their performance. Therefore, pipe straightening devices are used to correct the pipes, ensuring that their straightness meets the required standards.

[0003] In existing pipe straightening devices, the pipe is often placed under a hydraulic press and the deformation point is aligned with the output end of the hydraulic press to straighten the pipe. This process makes it inconvenient to move or rotate the pipe. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] This utility model provides a pipe straightening device, comprising:

[0006] The workbench has a support frame at its top, on which the pipes are movably placed. The workbench is equipped with a translation structure and a rotation structure for lifting and lowering.

[0007] The translation structure includes a plurality of rollers spaced apart along the length of the pipe, the axis of rotation of the rollers being perpendicular to the length of the pipe; it also includes a motor that drives the rollers to rotate.

[0008] The rotating structure includes multiple roller groups spaced apart along the length of the pipe. Each roller group includes two parallel rollers, the axis of rotation of which is parallel to the length of the pipe. It also includes a motor that drives one of the rollers in the roller group to rotate.

[0009] When only the first roller of the translational structure contacts the pipe, the first rotating roller drives the pipe to move horizontally; when only the second roller of the rotating structure contacts the pipe, the second rotating roller drives the pipe to rotate along its own axis.

[0010] As a preferred embodiment of the above technical solution, the first roller and the roller assembly are respectively installed by mounting bracket 1 and mounting bracket 2 movably set on the workbench. A lifting component is provided on the workbench below each mounting bracket 1 and mounting bracket 2, and the lifting component drives the corresponding mounting bracket 1 and mounting bracket 2 to move up and down.

[0011] As a preferred embodiment of the above technical solution, it also includes a bracket mounted on the workbench, on which a distance measuring sensor is mounted.

[0012] As a preferred embodiment of the above technical solution, the support is further provided with a hydraulic press, which includes a correction end that moves in the vertical direction.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a translational and rotational structure, allowing multiple rollers to move the pipe horizontally; the roller assembly can also rotate the pipe along its own axial direction, thus enabling rapid adjustment of the pipe's position; and in conjunction with a distance sensor and a hydraulic press, it enables rapid detection and correction of the pipe.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, Figure 1 The diagram shown is a front view of the overall pipe straightening device in the embodiment; Figure 2 The diagram shown is a front view of the translation structure in the embodiment; Figure 3 The diagram shown is a front view of the rotating structure in the embodiment; Figure 4 The diagram shown is a side view of the rotating structure and the tubing in the embodiment.

[0023] This device includes:

[0024] The workbench 10 has a support frame 11 at the top, and the pipe 1 is movably placed on the support frame 11. The workbench 10 is equipped with a translation structure 20 and a rotation structure 30 for lifting and lowering.

[0025] The translation structure 20 includes a plurality of rollers 22 spaced apart along the length of the pipe 1, the axis of rotation of the rollers 22 being perpendicular to the length of the pipe 1; it also includes a motor that drives the rollers 22 to rotate.

[0026] The rotating structure 30 includes a plurality of roller groups spaced apart along the length of the pipe 1. Each roller group includes two parallel rollers 32, the axis of rotation of which is parallel to the length of the pipe 1. The structure also includes a motor 34, which drives one of the rollers 32 in the roller group to rotate.

[0027] When only the roller 22 of the translation structure 20 contacts the pipe 1, the rotating roller 22 drives the pipe 1 to move in the horizontal direction; when only the roller group of the rotation structure 30 contacts the pipe 1, the rotating roller 32 drives the pipe 1 to rotate in its own axial direction.

[0028] Through the translation structure 20 and the rotation structure 30, multiple rollers 32 can drive the pipe 1 to move in the horizontal direction; the roller group can drive the pipe 1 to rotate along its own axial direction, thereby realizing the rapid adjustment of the position of the pipe 1.

[0029] Specifically, such as Figure 1 As shown, the X-axis of the coordinate system is horizontal, the Y-axis is vertical, and the dashed line represents the centerline of pipe 1. Rollers 22 and roller sets are mounted via mounting brackets 21 and 31, which are movably mounted on the worktable 10. There are five rollers 22 in total, with motors 1 mounted on the mounting brackets 21 on the two outermost rollers. There are four roller sets, with motors 34 mounted on the mounting brackets 31 on each side of roller 32.

[0030] A lifting component 40 is provided on the workbench 10 and below each mounting bracket 21 and mounting bracket 31. The lifting component 40 drives the corresponding mounting bracket 21 and mounting bracket 31 to move up and down, adjusting the contact state between the roller 22 or roller 32 and the pipe 1.

[0031] The lifting component 40 is a hydraulic cylinder. By controlling the lifting component 40, the roller 22 of the translation structure 20 can be adjusted to contact the pipe 1, or the roller group of the rotation structure 30 can be adjusted to contact the pipe 1, thereby realizing the adjustment of the translation or rotation of the pipe 1.

[0032] like Figure 1 As shown, Figure 1 The diagram shown is a front view of the overall pipe straightening device in the embodiment;

[0033] It also includes a bracket 12 set on the workbench 10, on which a distance sensor 13 is mounted.

[0034] The ranging sensor 13 detects deformation points on the surface of the pipe 1 below, and performs a comprehensive inspection of the surface of the pipe 1 by translating or rotating the pipe 1. Furthermore, by collecting data from multiple points, it detects the highest point of the bend in the pipe 1.

[0035] It also includes a controller 131, and the ranging sensor 13 is electrically connected to the controller 131.

[0036] The support 12 is also equipped with a hydraulic press 14, which includes a correction end 15 that moves in the vertical direction;

[0037] The correction end 15 can be a correction block. The correction block can be pressed down by the output end of the hydraulic press 14 to correct the highest point of the bend on the surface of the pipe 1.

[0038] Working principle: When this device is in use, after the pipe 1 is conveyed to the support frame 11 of the workbench 10, the translation structure 20 and the rotation structure 30 drive the pipe 1 to translate and rotate respectively. During the rotation of the pipe 1, the distance sensor 13 performs a comprehensive detection on the surface of the pipe 1. By collecting data from multiple points, the distance sensor 13 locates the highest point of the bend of the pipe 1 and moves this point to the correction end 15 below the hydraulic press 14 to straighten the point. After straightening, the distance sensor 13 performs detection again. After the set value is reached, the pipe is output.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
