Description

TECHNICAL FIELD

[0001] The utility model relates to welded pipe cleaning technical field especially relates to a welded pipe cleaning device for welded pipe machining. BACKGROUND

[0002] Welded pipe, also known as welded steel pipe, is a kind of pipe material made of steel strip or steel plate through welding process. After the steel strip or steel plate is formed by coiling, it is welded together by high-frequency welding or submerged arc welding, etc. High-frequency welding is to heat the edge of the steel strip to the welding temperature rapidly by using the skin effect and proximity effect of high-frequency current, and then apply pressure to weld it. Submerged arc welding is to weld under the arc of the welding agent layer, and the weld quality is high, which is suitable for the production of welded pipes with larger diameter and thicker wall. Straight seam welded pipes are widely used in the fields of building structure pipes (such as scaffold pipes) and low-pressure fluid conveying pipes (such as water pipes). For example, in the construction industry, the scaffold made of straight seam welded pipe can provide a safe working platform for construction workers. The steel strip is coiled on the forming machine in a spiral manner, and welding is carried out at the same time. The main welding method is submerged arc welding. Due to the characteristics of the spiral weld, compared with straight seam welded pipes, spiral welded pipes have better performance in bearing pressure. In the production process of spiral welded pipes, the width of the steel strip and the spiral angle will affect the size and performance of the welded pipe, which is mainly used for the transportation of oil, natural gas, etc. Because in the long-distance transportation process, the spiral welded pipe can bear high internal pressure and external environmental pressure, and different diameters and wall thicknesses of pipe materials can be produced according to the transportation requirements. Welded pipe cleaning is an important link in the production process or use process of welded pipe. In the production process of welded pipe, there may be oil stains such as lubricating oil and rust-proof oil attached to the surface of the welded pipe. If these oil stains are not removed, it will affect the subsequent processing, such as coating, electroplating, etc. For example, during powder coating, oil stains will cause the adhesion of powder to decrease, making the coating easy to peel off.

[0003] In the prior art, when cleaning the welded pipe, the cavitation effect of ultrasonic waves in liquid is used. When the ultrasonic waves propagate in the cleaning liquid, countless micro cavitation bubbles are generated. When these bubbles come into contact with the dirt on the surface of the welded pipe, they will burst instantly, producing a strong impact force to strip the dirt from the surface of the welded pipe. The welded pipe is placed in the ultrasonic cleaning tank filled with cleaning liquid, and the ultrasonic generator is turned on. The cleaning time is adjusted according to the degree of contamination and material of the welded pipe, etc. Generally, it is several minutes to tens of minutes. It has good effect on cleaning small particles on the surface of the welded pipe and internal dirt of precision welded pipe. Some difficult-to-remove dirt and impurities still need to be manually confirmed and cleaned to ensure that the welded pipe is clean after cleaning. Finally, the cleaned welded pipe is dried to ensure that the welded pipe can be used normally subsequently.

[0004] However, in the prior art, when multiple welded pipes are placed together in the cleaning tank for cleaning, the welded pipes are prone to collide with each other and be damaged, so that the welded pipes cannot be used after cleaning, and the cleaning efficiency of normal welded pipes is reduced.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0023] Referring to Figures 1-5The utility model provides a welded pipe cleaning device for welded pipe processing, which comprises a cleaning tank 1 and a conveying belt 2 fixedly connected to the top of the cleaning tank 1, and the cleaning tank 1 and the conveying belt 2 are both existing mature technologies. A plurality of fixed rods 3 are fixedly connected to the surface of the conveying belt 2. One end of the fixed rod 3 is provided with a force receiving rod 5 in the shape of an inverted T through a telescopic mechanism 4. The telescopic mechanism 4 can move upward when the partition plate 8 is pressed by the welded pipe, preventing damage caused by the hard collision between the partition plate 8 and the welded pipe. The bottom of the force receiving rod 5 is provided with two extension rods 7 through an adjusting mechanism 6. The adjusting mechanism 6 can adjust the distance between the two extension rods 7, so that the welded pipe of different diameters can be quickly adjusted and then separated and protected during cleaning. The extension rod 7 increases the length of the partition plate 8, facilitating the placement of the partition plate 8 inside the cleaning tank 1. The bottom of the extension rod 7 is fixedly connected with the partition plate 8. During the cleaning of the welded pipe, the welded pipe is placed inside the cleaning tank 1, and then the conveying belt 2 is started. The operation of the conveying belt 2 can drive the fixed rod 3 to operate, so that the fixed rod 3 can drive the two extension rods 7 below the force receiving rod 5 to move to the surface of the welded pipe in the cleaning tank 1. Then, the two partition plates 8 separate the welded pipe through the telescopic mechanism 4, preventing the welded pipes from colliding with each other. The movement of the partition plate 8 driven by the conveying belt 2 causes the welded pipe to roll inside the cleaning tank 1. The surface of the partition plate 8 is fixedly connected with a cleaning pad 9. During the movement of the partition plate 8 inside the cleaning tank 1, the surface of the welded pipe can be cleaned by the cleaning pad 9 on the surface of the partition plate 8, which can improve the cleaning effect of the welded pipe.

[0024] Further, the telescopic mechanism 4 comprises a T-shaped telescopic groove 401 formed in the fixed rod 3. One end of the force receiving rod 5 is inserted into the telescopic groove 401. Two anti-dropping rods 402 are fixedly connected to the surface of the force receiving rod 5 and are respectively inserted into the two ends of the telescopic groove 401. When the partition plate 8 is blocked by the welded pipe, the force receiving rod 5 will be subjected to an upward force. At this time, the force receiving rod 5 can move upward into the telescopic groove 401. When the blockage is removed, the force receiving rod 5 can descend by gravity. At this time, the force receiving rod 5 can be clamped in the telescopic groove 401 by the anti-dropping rods 402, preventing the force receiving rod 5 from completely falling out of the telescopic groove 401 and ensuring the normal use of the partition plate 8.

[0025] Further, the top of the force receiving rod 5 is elastically connected to the top of the telescopic groove 401 through a compression spring 403. When the partition plate 8 is blocked by the welded pipe, the compression spring 403 can cause the partition plate 8 to press the welded pipe, so that the cylindrical welded pipe can be subjected to external force to rotate and no longer block the partition plate 8. The partition plate 8 can actively separate the welded pipe, which can better protect the welded pipe.

[0026] Further, the adjusting mechanism 6 comprises a T-shaped adjusting groove 601 opened at the bottom of the force rod 5, and the top of the extension rod 7 is fixedly connected with a T-shaped adjusting block 602 which is slidingly connected to the inside of the adjusting groove 601. When the pipes with different diameters need to be cleaned, the position of the extension rod 7 can be changed by moving the adjusting block 602 in the adjusting groove 601, so that the distance between the two extension rods 7 is changed, and the distance between the two extension rods 7 can also drive the distance between the two partition plates 8 to change, and then the different pipes can be conveniently separated and cleaned by the cleaning pad 9, so that the pipes can be normally cleaned.

[0027] Further, the side surface of the force rod 5 is provided with a plurality of positioning grooves 603, and the side surface of the adjusting block 602 is provided with an insertion groove 604, wherein the inside of two positioning grooves 603 is slidingly connected with a screw rod 605 which is screwedly connected with the inside of the adjacent insertion groove 604. When the position of the adjusting block 602 needs to be adjusted, first, the screw rod 605 is rotated to disengage from the positioning groove 603 and the positioning groove 603, and then the adjusting block 602 is moved to slide in the inside of the adjusting groove 601. After the position of the adjusting block 602 is adjusted, the screw rod 605 is re-aligned with the insertion groove 604, and the screw rod 605 is rotated to be screwedly connected with the insertion groove 604 and the positioning groove 603, so that the adjusting block 602 is fixed in the inside of the adjusting groove 601, and then the distance between the two partition plates 8 can separate the corresponding pipes.

[0028] Further, the inside of the cleaning groove 1 is provided with two anti-blocking grooves 10. When the partition plate 8 is driven by the conveying belt 2 to enter the inside of the cleaning groove 1, the partition plate 8 will not be blocked by the cleaning groove 1 through the anti-blocking grooves 10, so that the partition plate 8 can conveniently enter the inside of the cleaning groove 1.

[0029] In summary:

[0030] When the butt welding pipe is cleaned, the screw rod 605 is rotated first, so that the screw rod 605 is separated from the insertion slot 604, then the adjusting block 602 is adjusted in the adjusting slot 601, after adjustment, the screw rod 605 is rotated into the positioning slot 603, and then the adjusting block 602 is fixed through the insertion slot 604, so that the spacing of the two partition plates 8 is fixed, then the conveying belt 2 is started, the conveying belt 2 drives the stress rod 5 to move through the fixed rod 3, and the stress rod 5 can drive the partition plate 8 into the cleaning tank 1 through the extension rod 7, at this time, the welding pipe is sent into the cleaning tank 1, and the welding pipe is separated by the partition plate 8, in this process, the welding pipe can be separated by the compression spring 403 and the telescopic slot 401, the stress rod 5 is moved up and down, and the welding pipe can be separated, and the stress rod 5 can be prevented from being separated from the telescopic slot 401 by the anti-dropping rod 402, after the welding pipe is separated by the partition plate 8, the partition plate 8 can move with the welding pipe in the cleaning tank 1, so that the welding pipe is cleaned in the cleaning tank 1, and the welding pipe can also be cleaned by the cleaning pad 9 on the surface of the partition plate 8, until the partition plate 8 is separated from the welding pipe, when the partition plate 8 enters the cleaning tank 1, the partition plate 8 can be conveniently separated in and out of the cleaning tank 1 by the blocking slot 10, through the above structure, the welding pipe can be conveniently separated when the welding pipe is cleaned, the damage caused by the mutual collision of the welding pipe is prevented, and the surface of the welding pipe can be better cleaned when being separated, the cleaning effect of the welding pipe is guaranteed, and the welding pipe can be safely cleaned.
