Description

Technical Field

[0001] This invention relates to the field of stainless steel welded pipe processing technology, specifically to a rapid deviation correction device for stainless steel welded pipes. Background Technology

[0002] Stainless steel welded pipes are made by rolling and forming steel or steel strips using machines and molds, and then welding them. They are mainly used in industries such as heat exchanger tubes, fluid pipes, pressure pipelines, mechanical structure pipes, and urban landscaping. During processing, stainless steel welded pipes may experience bending or deformation, requiring straightening and correction during the process to facilitate subsequent processing and use.

[0003] A stainless steel pipe forming and straightening device with patent application number CN202121192122.7 includes a worktable, a hydraulic push rod and a positioning device on the top of the worktable, and a straightening device. The straightening device includes a mounting base, a drive shaft and a moving block on the mounting base, and a transverse straightening roller on the moving block. In addition, the straightening device also includes a threaded rod, a floating plate and a vertical straightening roller. The straightening device straightens and corrects the welded pipe in both horizontal and vertical directions.

[0004] However, when the above-mentioned device corrects the welded pipe, it can only correct it in two fixed directions, horizontal and vertical, which is not very flexible. In addition, during the early processing of the welded pipe, other waste residues are easily adhered to it, which can affect the correction effect or the surface quality of the steel pipe during the correction process.

[0005] Based on this, the present invention designs a rapid correction device for stainless steel welded pipes to solve the above problems. Summary of the Invention

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1

[0049] Please refer to the accompanying drawings. This invention provides a technical solution:

[0050] A rapid deviation correction device for stainless steel welded pipes includes a base 1;

[0051] Multiple drive boxes 2 are evenly fixed on the top surface of the base 1 along the front-back direction. A rotating cylinder is rotatably connected in the drive box 2, and both ends of the rotating cylinder extend out of the drive box 2. A worm wheel 206 is fixed on the rotating cylinder inside the drive box 2. A worm 207 is meshed at the bottom of the worm wheel 206. The worm 207 is rotatably connected to the lower side wall of the drive box 2, and one end extends out of the drive box 2 and is connected to a motor.

[0052] The four rotating cylinders are arranged from front to back as a first rotating cylinder 201, a second rotating cylinder 202, a third rotating cylinder 203, and a fourth rotating cylinder 204. The first rotating cylinder 201 has annular plates fixed symmetrically at both ends, and multiple cleaning components are evenly arranged between the two annular plates along the circumferential direction. The inner sides of the second rotating cylinder 202 and the third rotating cylinder 203 are each symmetrically provided with two first correction components. The fourth rotating cylinder 204 has annular plates fixed symmetrically at both ends, and multiple second correction components are evenly arranged between the two annular plates along the circumferential direction.

[0053] When correcting the deviation of the welded pipe, the positions of the cleaning component, the first correction component and the second correction component are determined in advance according to the pipe diameter. The second rotating drum 202 and the third rotating drum 203 are rotated by the action of the worm 207 and the worm wheel 206 to adjust the angle and position of the first correction component so as to correspond to the correction position on the welded pipe.

[0054] The stainless steel welded pipe is moved and conveyed by an external conveying device or manually, passing through four rotating drums in sequence. When it passes the first rotating drum 201, the pipe stops moving. The first rotating drum 201 is driven by a motor, worm 207 and worm wheel 206 to rotate multiple cleaning components, so as to scrape and clean the outside of the welded pipe in a circumferential direction, so as to avoid other waste residues adhering to the side wall of the welded pipe, which would affect the correction effect of the subsequent first and second correction components or damage the surface structure of the steel pipe.

[0055] After cleaning, the welded pipe continues to move backward. During the movement, it passes through the second rotating drum 202 and the third rotating drum 203. The two first correction components correct the deviation of the welded pipe. When it moves to the fourth rotating drum 204, the welded pipe stops moving. The motor, worm 207 and worm wheel 206 drive the fourth rotating drum 204 to rotate multiple second correction components. The multiple second correction components correct the deviation of the welded pipe in the circumferential direction, thereby improving the correction effect of the welded pipe.

[0056] During the movement of the welded pipe, the first correction components at the second rotating drum 202 and the third rotating drum 203 correct the welded pipe in the length direction. When the welded pipe stops moving, the cleaning component at the first rotating drum 201 cleans the welded pipe, and the second correction component at the fourth rotating drum 204 corrects the welded pipe in the circumferential direction. The four rotating drums work in coordination with the movement of the welded pipe to improve processing efficiency.

[0057] A pulley can be provided at the outer end of the worm 207 at the first rotating drum 201 and the fourth rotating drum 204, and the two drives can be connected by a transmission belt. A motor is connected to the end of one of the worm 207, so that the two worms 207 at the first rotating drum 201 and the fourth rotating drum 204 can rotate synchronously and reduce the number of motors.

[0058] The cleaning assembly includes a plurality of first fixed boxes 3 evenly arranged along the circumference. The two ends of the first fixed boxes 3 are fixedly connected to the annular plates on both sides of the first rotating drum 201, and a gap is left between the inner side and the inner wall of the first rotating drum 201 so that the waste residue and other debris cleaned off during the rotation of the first rotating drum 201 can move along the inner wall of the first rotating drum 201 and be concentrated at the bottom of the first rotating drum 201 for subsequent cleaning. A movable plate 301 is provided on the outer side of the first fixed box 3, and a scraper 302 is fixed in the middle of the outer side of the movable plate 301. The scraper 302 is arranged along the radial direction of the first rotating drum 201.

[0059] Two connecting rods 305 are symmetrically arranged and rotatably connected on the inner side of the movable plate 301. Two adjusting blocks 304 are symmetrically arranged and slidably connected inside the first fixed box 3. The inner end of the connecting rod 305 is rotatably connected to the adjusting block 304 on the corresponding side. A first screw 306 is rotatably connected in the first fixed box 3. The threads on the two sides of the first screw 306 are turned in opposite directions and are threadedly connected to the two adjusting blocks 304 respectively.

[0060] One end of the first screw 306 extends out of the first rotating cylinder 201 and is fixed with a first gear ring 308. A central cylinder 205 is fixed at the front end of the first rotating cylinder 201. A rotating ring plate 303 is rotatably connected to the outer side of the central cylinder 205. A first gear ring 308 is fixed on the inner side of the rotating ring plate 303, and multiple first gears 307 mesh with the first gear ring 308.

[0061] When it is necessary to clean the outer surface of the welded pipe, the rotating ring plate 303 is rotated, and the first screw 306 is rotated through the transmission of the first gear ring 308 and the first gear 307. The two adjusting blocks 304 are driven to move inward simultaneously through the opposite threads, thereby moving the moving plate 301 outward through the connecting rod 305. The multiple moving plates 301 drive the scraper 302 to move towards the center of the first rotating drum 201, thereby contacting the outer surface of the welded pipe. When the first rotating drum 201 rotates, it drives the scraper 302 to rotate around the outside of the welded pipe, so as to perform scraping and cleaning operations on the outer surface of the welded pipe.

[0062] Multiple operating handles are evenly fixed on the outer side of the rotating ring plate 303 along the circumferential direction, which facilitates the rotation of the rotating ring plate 303 and thus adjusts the position of the moving plate 301.

[0063] The annular plate located at the rear end of the first rotating drum 201 is detachably connected to the rear end of the first rotating drum 201 so that when the device is not in operation, the waste residue accumulated at the bottom of the first rotating drum 201 can be cleaned by removing the annular plate at the rear end.

[0064] The first straightening assembly includes two first movable frames 401 arranged symmetrically at the top and bottom. Multiple first straightening wheels 402 are evenly arranged and rotatably connected on the opposite sides of the two first movable frames 401. The other side of the first movable frame 401 is connected to the inner wall of the second rotating drum 202 or the third rotating drum 203 through a first hydraulic telescopic rod 4. The first movable frame 401 drives the first straightening wheels 402 to move towards the middle position through the first hydraulic telescopic rod 4, thereby adjusting the distance between the two first straightening wheels 402 according to the diameter of the welded pipe.

[0065] The second straightening assembly includes multiple second fixed boxes 5 evenly arranged along the circumferential direction. The two ends of the second fixed boxes 5 are fixed to the annular plates at both ends of the fourth rotating drum 204. The second fixed boxes 5 are symmetrically arranged with second hydraulic telescopic rods 503. The outer ends of the two hydraulic telescopic rods extend into the second fixed boxes 5 and are jointly fixed with a second movable frame 501. The second movable frame 501 is rotatably connected with a second straightening wheel 502. The positions of the second movable frame 501 and the second straightening wheel 502 are adjusted by the second hydraulic telescopic rods 503 so that the positions of the multiple second straightening wheels 502 correspond to the outer wall of the welded pipe. When the fourth rotating drum 204 rotates and drives the multiple second straightening wheels 502 to rotate, the multiple second straightening wheels 502 in the circumferential direction correct and straighten the circumferential surface of the welded pipe.

[0066] Example 2

[0067] The structure of this embodiment is basically the same as that of embodiment one. The difference is that a conveying assembly is provided on the base 1 at the position between two adjacent drive boxes 2. The conveying assembly includes a fixing plate 101 symmetrically fixed on both sides of the top surface of the base 1. Two parallel conveying wheels 6 are symmetrically arranged between the upper parts of the two fixing plates 101, and two parallel conveying wheels 6 are also symmetrically arranged at the lower part. A rotating shaft 601 is fixed at the center of the conveying wheel 6. An adjustment assembly is provided on the outside of the fixing plate 101. The rotating shaft 601 is rotatably connected to the adjustment assembly on the corresponding side.

[0068] One end of the two rotating shafts 601 located below extends out of the adjustment assembly and is fixed with a transmission gear 602. The two transmission gears 602 mesh together with a drive gear 102, and the motor of the drive gear 102 is fixedly connected to the base 1 through a bracket. A first pulley 105 is coaxially fixed on the drive gear 102. One end of the two rotating shafts 601 located above is fixed with a second pulley 606, and the first pulley 105 and the second pulley 606 are connected by a transmission belt.

[0069] The upper and lower parts of the fixed plate 101 are symmetrically provided with arc-shaped grooves 103, the rotating shaft 601 is located in the corresponding arc-shaped grooves 103, and the center of the two arc-shaped grooves 103 coincides with the center of the drive gear 102.

[0070] When the welded pipe is conveyed by the conveying assembly, the welded pipe is located between the upper and lower conveying wheels 6. The position of the rotating shaft 601 and the conveying wheels 6 can be adjusted by the adjusting assembly, and the upper and lower conveying wheels 6 can be moved closer to each other along the arc groove 103. The vertical distance between the upper and lower conveying wheels 6 can be adjusted to accommodate welded pipes of different diameters and clamp the welded pipe. Then, through the transmission of the drive gear 102 and the transmission gear 602, as well as the transmission of the first pulley 105 and the second pulley 606, the rotating shaft 601 drives the upper and lower conveying wheels 6 to rotate simultaneously and in opposite directions, thus driving the welded pipe.

[0071] The transmission ratio of the drive gear 102 and the transmission gear 602 is the same as that of the first pulley 105 and the second pulley 606, so that the upper and lower conveyor wheels 6 rotate at the same speed.

[0072] The adjustment assembly includes two symmetrically and vertically arranged second screws 104. The second screws 104 are rotatably connected to the fixed plate 101, and a motor is connected to the bottom end. The threads on the upper and lower sections are in opposite directions. The upper and lower parts of the two second screws 104 are connected to a movable seat 604. The movable seat 604 is provided with a slide groove 605. Two sliders 603 are symmetrically arranged and slidably connected in the slide groove 605. The sliders 603 are connected to the end of the slide groove 605 by springs, and the rotating shaft 601 is rotatably connected to the sliders 603 at the corresponding positions.

[0073] When the position of the conveyor wheel 6 needs to be adjusted, the second screw 104 is rotated by the motor, causing the two moving seats 604 to move closer to each other. The rotating shaft 601 is moved along the arc groove 103 via the slide groove 605 and the slider 603. The slider 603 automatically adjusts its position in the slide groove 605. When the rotating shaft 601 moves along the arc groove 103, it drives the conveyor wheel 6 to move, thereby adjusting the position and spacing of the upper and lower conveyor wheels 6. The transmission gear 602 rotates around the drive gear 102, keeping the transmission gear 602 and the drive gear 102 always meshed. The second pulley 606 rotates around the first pulley 105, keeping the first pulley 105 and the second pulley 606 in stable transmission for subsequent driving.

[0074] Among them, the conveyor wheel 6 has a limiting groove around the center of the wheel surface. The two side walls of the limiting groove are symmetrically inclined. The limiting grooves on multiple conveyor wheels 6 together restrict the position of the welded pipe during conveying, so as to avoid the position of the welded pipe being skewed during conveying. Rubber pads are fixed on the side walls of the limiting groove to increase the friction between the welded pipe and the limiting groove and improve the conveying stability.

[0075] Example 3

[0076] The structure of this embodiment is basically the same as that of embodiment one. The difference is that scrapers 302 are fixed on half of the movable plates 301, and brush bristles are evenly distributed on the other half of the movable plates 301. The movable plates 301 with brushes and the movable plates 301 with scrapers 302 are arranged alternately. While scraping and cleaning the outer wall of the welded pipe by scraping with scrapers 302, secondary cleaning is performed by brush bristles, which further improves the cleaning effect of the side wall of the welded pipe.
