A device for preventing deformation of welded pipe rolls

Abstract

This utility model discloses a device for preventing deformation of welded coiled pipes, belonging to the field of welded coiled pipes. It includes a work frame, with a welding assembly installed at the top and an anti-deformation assembly on the side wall of the work frame. The anti-deformation assembly includes a material feed plate rotatably connected to the side wall of the work frame via a rotating shaft, and a slide block fixedly connected to the bottom of the work frame. A pressure-bearing slide rod is slidably connected to the inner wall of the slide block. Through the coordinated use of these devices, the storage effect of the coiled pipe after welding is improved, preventing deformation caused by the outer wall impact during the free fall of the coiled pipe. Through the cooperation of components such as the rotating shaft, material feed plate, slide block, and pressure-bearing slide rod, when the hydraulic push rod pushes against the base, the pressure plate abuts against the pressure-bearing slide rod, causing the material feed plate to rotate against the outer wall of the rotating shaft, supporting the welded coiled pipe. The guide allows the coiled pipe to slide into the storage box for storage, improving the processing quality of the coiled pipe.

Description

Technical Field

[0001] This utility model relates to the field of welded pipe rolling technology, specifically a device for preventing deformation of welded pipe rolling. Background Technology

[0002] Welded coiled pipe is a type of steel pipe made by rolling steel plates or strips into a tubular shape and then connecting the joints using welding processes (such as submerged arc welding, high-frequency welding, etc.). Its main difference from seamless steel pipe is that seamless steel pipe is formed by piercing and rolling steel billets, resulting in no joints; while welded coiled pipe relies on welding after the steel plate is rolled, resulting in one or more weld seams.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN209736937U) discloses a pipe joint welding device, comprising a base, a column, a first horizontal beam, a second horizontal beam, a mandrel, and a locking mechanism. Compared to existing technologies, this utility model involves inserting the pipe to be welded onto the mandrel from the end furthest from the column, with the joint facing upwards. The locking mechanism then secures the non-column end of the mandrel, maintaining a stable height difference between the non-column end and the second horizontal beam. A pressing mechanism on the second horizontal beam presses down on the pipe to be welded, ensuring full contact between the pipe and the negative electrode strip on the mandrel. Finally, the translation drive mechanism of the first horizontal beam drives the welding torch to weld the pipe joint. The locking mechanism prevents significant deflection deformation caused by the mandrel being supported at one end, ensuring the mandrel remains parallel to the second horizontal beam. This results in stable and reliable welding quality, high welding efficiency, and significantly reduced labor intensity for operators.

[0004] Although the aforementioned patent reduces the deflection caused by uneven weight at both ends of the rolled tube during welding by setting up a locking mechanism and cooperating with each component, ensuring that the mandrel remains parallel to the second horizontal beam and improving welding stability, after the rolled tube is welded, it is often pushed directly out of the welding frame, allowing it to fall freely into the storage box. However, during the fall, the ends of the rolled tube may be bumped due to collisions, leading to deformation of the rolled tube, which is very detrimental to improving the processing quality of the rolled tube.

[0005] Therefore, this utility model provides a device for preventing deformation of welded pipe coils to solve the above problems. Utility Model Content

[0007] This utility model provides a device for preventing deformation of welded pipe rolls, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A device for preventing deformation of welded pipe rolls includes a work frame, a welding assembly installed at the top of the work frame, and anti-deformation components provided on the side walls of the work frame.

[0011] The anti-deformation component includes a material feeding plate rotatably connected to the side wall of the work frame via a rotating shaft. A slide block is fixedly connected to the bottom end of the work frame. A pressure-bearing slide rod is slidably connected to the inner wall of the slide block. A rubber plate is fixedly connected to the bottom end of the material feeding plate corresponding to the pressure-bearing slide rod.

[0012] As a preferred technical solution of this application, the anti-deformation component further includes a micro motor installed at the bottom of the feeding plate. The output end of the micro motor is fixedly sleeved with a feeding rod. The outer wall of the rubber plate is fixedly connected with a start button. The outer wall of the start button is electrically connected to the control end of the micro motor through a wire.

[0013] As a preferred technical solution of this application, the lower end of the pressure-bearing slide rod is rotatably connected to a pulley, and the number of pulleys is several; the upper end of the pressure-bearing slide rod is rotatably connected to a universal ball bearing.

[0014] As a preferred technical solution of this application, the welding assembly includes a hydraulic push rod installed at the bottom of the work frame, a pressure plate is fixedly sleeved on the outer wall of the output end of the hydraulic push rod, and a base is installed on the output end of the hydraulic push rod.

[0015] As a preferred technical solution of this application, the welding assembly further includes a retainer mounted on the top of the work stand, an electric push rod mounted on the inner wall of the retainer, and a side seat mounted on the output end of the electric push rod.

[0016] As a preferred technical solution of this application, the welding assembly further includes a stand fixedly connected to the top of the work frame, a welding machine is installed on the outer wall of the stand, and a hydraulic push cylinder is installed on the outer wall of the stand corresponding to the welding machine.

[0017] As a preferred technical solution of this application, a limiting plate is fixedly connected to the upper top of the feeding plate, and ventilation holes are provided on the outer wall of the limiting plate.

[0018] (III) Beneficial Effects

[0019] By incorporating anti-deformation components, the coordinated operation of various parts enhances the storage efficiency of the welded tube, preventing deformation caused by impacts to the outer wall during free fall. The combination of components such as the rotating shaft, feeding plate, slide block, and pressure-bearing slide rod allows the pressure plate to abut against the pressure-bearing slide rod when the hydraulic push rod pushes against the base. This causes the feeding plate to rotate against the outer wall of the rotating shaft, supporting the welded tube and guiding it to slide into the storage box for final storage, thus improving the processing quality of the tube.

[0026] 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.

[0027] This utility model provides a device for preventing deformation of welded pipe coils, such as... Figures 1-4 As shown, the welding coil anti-deformation device includes a work frame 1, a welding assembly is installed on the top of the work frame 1, and an anti-deformation assembly is provided on the side wall of the work frame 1.

[0028] The anti-deformation component includes a material feeding plate 3 rotatably connected to the side wall of the work frame 1 via a rotating shaft 2, a slide block 4 fixedly connected to the bottom end of the work frame 1, a pressure-bearing slide rod 5 slidably connected to the inner wall of the slide block 4, and a rubber plate 6 fixedly connected to the bottom end of the material feeding plate 3 corresponding to the pressure-bearing slide rod 5.

[0029] The anti-deformation component also includes a micro motor 7 installed at the bottom of the feed plate 3. The output end of the micro motor 7 is fixedly sleeved with a feeding rod 8. The outer wall of the rubber plate 6 is fixedly connected with a start button 9. The outer wall of the start button 9 is electrically connected to the control end of the micro motor 7 through a wire 10.

[0030] The lower end of the pressure-bearing slide rod 5 is rotatably connected to a pulley 11, and there are several pulleys 11. The upper end of the pressure-bearing slide rod 5 is rotatably connected to a universal ball bearing 12.

[0031] The welding assembly includes a hydraulic push rod 13 installed at the bottom of the work frame 1. A pressure plate 14 is fixedly sleeved on the outer wall of the output end of the hydraulic push rod 13, and a base 15 is installed on the output end of the hydraulic push rod 13.

[0032] Specifically, by setting up anti-deformation components, the quality of tube rolling can be improved through the cooperation of various parts, avoiding deformation caused by bumps during material feeding that would affect the processing quality. During processing, the operation of the hydraulic push rod 13 causes the pressure plate 14 at its output end to rise longitudinally, driving the base 15 to move. When the pressure plate 14 moves longitudinally, since the lower end of the work frame 1 is fixedly connected to the slide block 4, and the slide block 4 has a sliding pressure rod 5 inside, and the lower end of the pressure rod 5 is equipped with multiple pulleys 11, when the pressure rod 5 is pressed, it will slide inside the slide block 4. The material plate 3 moves laterally and is squeezed to rotate and lift on the outer wall of the rotating shaft 2. At the same time, when the pressure slide rod 5 slides, its end will abut against the start button 9 at the bottom of the rubber plate 6. The start button 9, together with the wire 10, controls the micro motor 7 to rotate, so that its output end drives the material guide rod 8 to rotate, thereby guiding the falling coil tube to slide into the designated storage box. This component has a simple structure and strong practicality. Through the synchronous operation of each component, it can avoid the phenomenon of the welded coil tube falling directly into the storage box and causing bumps and deformation, thus improving both processing quality and processing efficiency.

[0033] The welding assembly also includes a retainer 16 mounted on the top of the work stand 1, an electric push rod 17 mounted on the inner wall of the retainer 16, and a side seat 18 mounted on the output end of the electric push rod 17.

[0034] The welding assembly also includes a stand 19 fixedly connected to the top of the work frame 1. A welding machine 20 is installed on the outer wall of the stand 19. A hydraulic push cylinder 21 is installed on the outer wall of the stand 19 corresponding to the welding machine 20. The input end of the hydraulic push cylinder 21 is fixedly connected to the output end of the hydraulic push rod 13 through a hydraulic pipe 22.

[0035] A limiting plate 23 is fixedly connected to the top of the feeding plate 3, and ventilation holes are provided on the outer wall of the limiting plate 23.

[0036] Specifically, through the setting of the welding components, the plate can be quickly rolled into shape by the retainer 16 and the electric push rod 17 installed inside, in conjunction with the welding machine 20 on the outer wall of the upright frame 19. After the welding machine 20 finishes welding, the welded rolled tube can be pushed to the unloading plate 3 by the setting of the hydraulic push cylinder 21, thereby completing the processing procedure.

[0037] 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.
