Description

Technical Field

[0001] This utility model relates to the field of welded pipe processing technology, and in particular to a guide mechanism for welded pipe processing. Background Technology

[0002] Welded pipe refers to a steel pipe made by rolling steel plates or strips into a tubular shape and welding the seam. It is one of the main products of the steel pipe industry, and its main difference from seamless steel pipe lies in the presence of a weld seam. During the processing of welded pipe, multiple sections of the pipe often need to be welded and lengthened. This lengthening process requires the assistance of an external guiding mechanism. This guiding mechanism ensures the accuracy, stability, and reliability of the pipe's movement, preventing misalignment during transport. However, existing guiding mechanisms have some shortcomings:

[0003] The existing guide mechanism used for welded pipe processing cannot quickly remove the welded pipe when unloading the extended welded pipe after welding is completed. Instead, it is necessary to push the welded pipe out, which is inconvenient and wastes a lot of time. In addition, the welded pipe needs to be manually pushed and adjusted during the welding guide process. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a guiding mechanism for welded pipe processing.

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

[0006] A guide mechanism for welded pipe processing includes a worktable. A rectangular groove is formed through the outer wall of one top end of the worktable, and a first mounting plate is fixed to the inner wall of the rectangular groove by bolts. A rectangular through slot is formed through the outer wall of the other top end of the worktable, and sliding slots are formed on both inner walls of the rectangular through slots. Sliding blocks are slidably inserted into the inner walls of the sliding slots, and a second mounting plate is welded between the two sliding blocks. Rotating shafts are rotatably mounted on the top of both the second mounting plate and the first mounting plate at equal intervals. A limit pin is welded at the top center of the rotating shaft. A guide wheel is inserted into the outer wall of the limit pin, and a limit block is screwed to the top of the limit pin. A gear is welded to the bottom outer wall of the rotating shaft, and a rack meshes with one side of the gear. A servo cylinder is connected to one side outer wall of the rack. A second electric telescopic rod is connected to the middle of one side outer wall of the second mounting plate.

[0007] As a further embodiment of this utility model: the side wall of the guide wheel has a through guide groove, and the length of the guide groove is half the circumference of the guide wheel, and the radius of one side of the guide wheel is larger than the radius of the other side.

[0008] As a further embodiment of this utility model: the top two outer walls of the workbench are fixed with supporting rollers by bolts, and the outer walls of the supporting rollers are bonded with anti-slip pads. The height of the top outer wall of the supporting rollers is lower than the height of the bottom outer wall of the guide wheel.

[0009] As a further embodiment of this utility model: a guide groove is formed through the bottom outer wall of the rack along the length direction, and a guide support rod is slidably inserted into the inner wall of the guide groove. The guide support rod is fixed to the lower outer wall of the first mounting plate and the second mounting plate respectively by screws.

[0010] As a further embodiment of this utility model: an electric slide rail is installed parallel to the width direction on the top of the workbench, and a slide block is slidably inserted into the inner wall of the electric slide rail, and a U-shaped bracket is fixed to the top outer wall of the slide block by screws.

[0011] As a further embodiment of this utility model: both ends of the top of the U-shaped bracket are slidably inserted with L-shaped fixing seats, and the bottom outer wall of each L-shaped fixing seat is connected with a first electric telescopic rod, and a bracket frame is rotatably installed between the two L-shaped fixing seats.

[0012] As a further improvement of this utility model: the outer wall of the bracket frame is covered with anti-slip rubber strips that are evenly distributed, and one side of the bracket frame is connected to a servo motor via a coupling.

[0013] Compared with the prior art, this utility model provides a guiding mechanism for welded pipe processing, which has the following beneficial effects:

[0014] The guide mechanism for welded pipe processing designed in this paper uses a second electric telescopic rod on the side to drive the second mounting plate to slide and adjust its position. This allows for adjustment of the distance between the guide wheels on both sides, enabling the welded pipe guide mechanism to quickly adapt to welded pipes of different diameters for clamping and guiding, greatly improving the practicality of the guide mechanism.

[0015] The guide mechanism for welded pipe processing designed in this paper guides the welded pipe after welding. By sliding the rack at the bottom to drive the gear to rotate, the guide wheel at the top can be rotated. After rotating 180 degrees, the distance between the guide wheels can be increased, allowing the welded pipe to be directly removed, thus reducing the time wasted in the past and improving work efficiency.

[0016] The guide mechanism for welded pipe processing designed in this paper uses a first electric telescopic rod to drive the anti-slip rubber belt to press down during the guiding and conveying process of the welded pipe. At the same time, a servo motor drives the anti-slip rubber belt to rotate, thereby pushing the welded pipe to move in a guided manner.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[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. Example

[0024] A guide mechanism for welded pipe processing, in this embodiment, as follows: Figure 1-4As shown, the workbench 1 has a rectangular groove 2 extending through its outer wall at one top end. A first mounting plate 3 is fixed to the inner wall of the rectangular groove 2 by bolts. A rectangular through slot 4 extends through its outer wall at the other top end of the workbench 1. Sliding slots 5 are formed on the inner walls of both sides of the rectangular through slot 4. Sliding blocks 6 are slidably inserted into the inner walls of the sliding slots 5. A second mounting plate 7 is welded between the two sliding blocks 6. Rotating shafts 8 are rotatably mounted at equal intervals on the top of both the second mounting plate 7 and the first mounting plate 3. A limit pin 9 is welded at the top center of the rotating shaft 8. A guide wheel 10 is inserted into the outer wall of the limit pin 9. A limit block 11 is screwed to the top of the limit pin 9. A gear 14 is welded to the bottom outer wall of the rotating shaft 8. A rack 15 meshes with one side of the gear 14. A servo cylinder 18 is connected to one side of the outer wall of the rack 15. A second electric telescopic rod 27 is connected to the middle of one side of the outer wall of the second mounting plate 7.

[0025] The second electric telescopic rod 27 on the side drives the second mounting plate 7 to slide and adjust its position, thereby adjusting the distance between the guide wheels 10 on both sides. This allows the welded pipe guiding mechanism to quickly adapt to welded pipes of different diameters for clamping and guiding, greatly improving the practicality of the guiding mechanism.

[0026] The guide wheel 10 has a guide groove 12 through its side wall, and the length of the guide groove 12 is half the circumference of the guide wheel 10. The radius of one side of the guide wheel 10 is larger than the radius of the other side. The top two outer walls of the worktable 1 are fixed with support rollers 13 by bolts, and the outer walls of the support rollers 13 are bonded with anti-slip pads. The height of the top outer wall of the support rollers 13 is lower than the height of the bottom outer wall of the guide wheel 10.

[0027] The outer wall of the bracket frame 24 is covered with anti-slip rubber strips 25 that are evenly distributed, and one side of the bracket frame 24 is connected to a servo motor 26 via a coupling.

[0028] The bottom outer wall of the rack 15 has a guide groove 16 extending through it along its length, and a guide support rod 17 is slidably inserted into the inner wall of the guide groove 16. The guide support rod 17 is fixed to the lower outer wall of the first mounting plate 3 and the second mounting plate 7 by screws.

[0029] The top of the workbench 1 is equipped with an electric slide rail 19 parallel to the width direction, and a slide block 20 is slidably inserted into the inner wall of the electric slide rail 19. A U-shaped bracket 21 is fixed to the top outer wall of the slide block 20 by screws.

[0030] When guiding the welded pipe, after welding is completed, the bottom rack 15 can be slid to drive the gear 14 to rotate, which will cause the top guide wheel 10 to rotate. After rotating 180 degrees, the distance between the guide wheels 10 can be increased, so that the welded pipe can be directly taken out, thereby reducing the time wasted in the past and improving work efficiency.

[0031] In this embodiment, the guiding mechanism is first connected to an external power supply for trial operation. After the trial operation, the second electric telescopic rod 27 is used to push the second mounting plate 7 for sliding adjustment. When the guide wheels 10 on both sides are close to each other, the two welded pipes that need to be guided are placed on the top of the support rollers 13 at the middle of both ends of the workbench 1. At this time, the servo cylinder 18 at the bottom is activated, and the servo cylinder 18 drives the rack 15 for sliding adjustment, thereby driving the gear 14 to rotate, which in turn drives the guide wheel 10 at the top to rotate. When the guide groove When aligning the welded pipe, the second electric telescopic rod 27 drives the guide wheel 10 to adapt and clamp the welded pipe. Then, the first electric telescopic rod 23 drives the anti-slip rubber belt 25 to press down. After pressing down the welded pipe, the servo motor 26 drives the anti-slip rubber belt 25 to rotate, which can push the welded pipe to move in a guide manner. After welding is completed, the servo cylinder 18 only needs to pull back the rack 15, which will drive the gear 14 to rotate 180 degrees, so that the distance between the guide wheels 10 increases and will not limit the welded pipe. At this time, the welded pipe can be directly removed. Example

[0032] A guide mechanism for welded pipe processing, such as Figure 1-4 As shown, this embodiment makes the following additions based on embodiment 1: both ends of the top of the U-shaped bracket 21 are slidably inserted with L-shaped fixing seats 22, and the bottom outer wall of the L-shaped fixing seats 22 is connected with a first electric telescopic rod 23, and a bracket frame 24 is rotatably installed between the two L-shaped fixing seats 22.

[0033] In this embodiment, during the guiding and conveying process of the welded pipe, the first electric telescopic rod 23 drives the anti-slip rubber belt 25 to press down, squeezing the welded pipe. At the same time, the servo motor 26 drives the anti-slip rubber belt 25 to rotate, thereby pushing the welded pipe to move in a guiding manner.

[0034] 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.
