Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically a grinding machine for producing double-sided submerged arc straight seam steel pipes. Background Technology

[0002] Double-sided submerged arc straight seam steel pipe is a type of steel pipe manufactured using a double-sided submerged arc welding process. This type of steel pipe has advantages such as high welding quality, beautiful weld seam, and good mechanical properties. It is widely used in industries such as petroleum, natural gas, chemical, power, water conservancy, and construction. After the production of double-sided submerged arc straight seam steel pipe is completed, the outer surface needs to be ground.

[0003] Some equipment on the market typically works by fitting one end of a steel pipe onto the outside of four support plates, then rotating a knob screw to move the cylinder backward along the shaft. At the same time, the cylinder, through the first and second support rods around its perimeter, drives the support plates around its perimeter to open outward until they support the inner wall of the steel pipe, thus fixing it in place. This method can fix steel pipes of different diameters.

[0004] However, in actual use, the above-mentioned equipment will cause the steel pipe to be stressed during the grinding process. The inner wall of the steel pipe is relatively smooth, which makes the steel pipe prone to rotation when subjected to grinding force, thus making it impossible to grind the steel pipe well. In view of this, we propose a grinding machine for the production of double-sided submerged arc straight seam steel pipe. Utility Model Content

[0005] The purpose of this invention is to provide a grinding machine for the production of double-sided submerged arc straight seam steel pipes, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding machine for producing double-sided submerged arc straight seam steel pipes, comprising a mounting base, a transmission device disposed on the upper surface of the mounting base, a mounting frame fixedly connected to the upper surface of the mounting base, a lifting device disposed on the upper surface of the mounting frame, a grinding device disposed on the side of the lifting device, and a limit component disposed on the upper surface of the transmission device, the limit component comprising:

[0007] The mounting component is fixedly connected to the upper surface of the transmission device. The mounting component is L-shaped and a transmission roller is rotatably connected to the inner wall side of the horizontal part of the mounting component.

[0008] A placement groove is provided on the side of the vertical part of the mounting component. A large electric telescopic rod is fixedly connected to the top of the inner wall of the placement groove, and a pressing component is fixedly connected to the end of the large electric telescopic rod.

[0009] A fixing groove is formed on the side of the vertical part of the mounting component. A motor is fixedly connected to the side of the vertical part of the mounting component. A bidirectional threaded rod is fixedly connected to the output end of the motor. A fixing block is threadedly connected to the outer surface of the bidirectional threaded rod. A pressing block is rotatably connected to the side of the fixing block.

[0010] Preferably, the side of the pressing block is provided with an arc-shaped surface, and the center of the pressing block corresponds to the center of the fixing block, which allows the pressing block to make better contact with the inner wall of the steel pipe.

[0011] Preferably, the position of the motor corresponds to the center of the fixing groove, and the fixing block is disposed inside the fixing groove, which allows the fixing block to move inside the fixing groove.

[0012] Preferably, the placement groove is located below the fixing groove, the center of the placement groove corresponds to the center of the mounting component, and a pressing component is provided inside the placement groove, which allows the pressing component to move inside the placement groove.

[0013] Preferably, the bottom of the mounting component is provided with an auxiliary component, the auxiliary component including a slide groove, the slide groove being formed at the bottom of the mounting component, a slider being slidably connected inside the slide groove, and a small electric telescopic rod being fixedly connected to the bottom of the slider.

[0014] Preferably, there are two slides, and the two slides are symmetrically arranged around the center of the mounting component, and the size of the small electric telescopic rod is adapted to the size of the slider.

[0015] Preferably, the slider is convex, and the size of the slider is adapted to the size of the groove.

[0016] Compared with the prior art, this utility model provides a grinding machine for the production of double-sided submerged arc straight seam steel pipes, which has the following beneficial effects:

[0017] 1. This grinding machine for producing double-sided submerged arc straight seam steel pipes, to prevent the steel pipe from rotating during grinding, places the steel pipe on the outer surface of the transmission roller. The steel pipe is then pushed to allow the pressing component to extend into the pipe. At this time, the large electric telescopic rod extends, bringing the bottom of the pressing component into contact with the inner wall of the steel pipe. The pressing component's pressure on the steel pipe, combined with the contact between the transmission roller and the outer surface of the steel pipe, effectively limits the steel pipe's position. Simultaneously, the motor starts, causing the bidirectional threaded rod to rotate, thus moving the fixed block towards the inner wall of the steel pipe. This allows the arc-shaped outer surface of the pressing block to contact the inner wall of the steel pipe, applying lateral pressure to the steel pipe and ensuring stable positioning, preventing rotation during grinding.

[0018] 2. In order to make the steel pipe more stable when moving, the grinding machine for producing double-sided submerged arc straight seam steel pipes has a lifting device that drives the grinding device to move downward after the steel pipe is limited, so that the grinding device can grind the outer surface of the steel pipe. At the same time, the transmission device drives the installation component to move, which allows the slider to move inside the slide groove, thereby allowing the small electric telescopic rod to support the bottom of the installation component, so that the installation component can stably support the movement of the steel pipe.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a grinding machine for producing double-sided submerged arc straight seam steel pipes, including a mounting base 1, a transmission device 5 on the upper surface of the mounting base 1, a mounting frame 2 fixedly connected to the upper surface of the mounting base 1, a lifting device 3 on the upper surface of the mounting frame 2, a grinding device 4 on the side of the lifting device 3, and a limiting component 6 on the upper surface of the transmission device 5. The limiting component 6 includes a mounting part 601, a transmission roller 602, a placement groove 603, a large electric telescopic rod 604, a pressing part 605, a fixing groove 606, a motor 607, a bidirectional threaded rod 608, a fixing block 609, and a pressing block 610.

[0025] In this embodiment of the utility model, the mounting member 601 is fixedly connected to the upper surface of the transmission device 5. The mounting member 601 is L-shaped. A transmission roller 602 is rotatably connected to the inner wall of the horizontal part of the mounting member 601. The outer surface of the transmission roller 602 is provided with a semi-circular protrusion, which increases the friction between the transmission roller 602 and the steel pipe, thereby preventing the steel pipe from rotating during grinding. A placement groove 603 is opened on the side of the vertical part of the mounting member 601. The placement groove 603 is located below the fixed groove 606, and the center of the placement groove 603 corresponds to the center of the mounting member 601. A pressing member 605 is provided inside the placement groove 603, which allows the pressing member 605 to move inside the placement groove 603. A large electric telescopic rod 60 is fixedly connected to the top of the inner wall of the placement groove 603. 4. A pressing member 605 is fixedly connected to the end of the large electric telescopic rod 604. A fixing groove 606 is opened on the side of the vertical part of the mounting member 601. A motor 607 is fixedly connected to the side of the vertical part of the mounting member 601. The position of the motor 607 corresponds to the center of the fixing groove 606. A bidirectional threaded rod 608 is fixedly connected to the output end of the motor 607. A fixing block 609 is threadedly connected to the outer surface of the bidirectional threaded rod 608. The fixing block 609 is set inside the fixing groove 606, which allows the fixing block 609 to move inside the fixing groove 606. A pressing block 610 is rotatably connected to the side of the fixing block 609. The side of the pressing block 610 is set with an arc-shaped surface. The center of the pressing block 610 corresponds to the center of the fixing block 609, which allows the pressing block 610 to better contact the inner wall of the steel pipe.

[0026] Meanwhile, an auxiliary component 7 is provided at the bottom of the mounting component 601. The auxiliary component 7 includes a sliding groove 701, which is located at the bottom of the mounting component 601. There are two sliding grooves 701, and the two sliding grooves 701 are symmetrically arranged around the center of the mounting component 601. A slider 702 is slidably connected inside the sliding groove 701. The slider 702 is convex and its size is adapted to the size of the sliding groove 701. A small electric telescopic rod 703 is fixedly connected to the bottom of the slider 702. The size of the small electric telescopic rod 703 is adapted to the size of the slider 702. In this way, after the steel pipe is limited, the lifting device 3 drives the grinding device 4 to move downward, so that the grinding device 4 can grind the outer surface of the steel pipe. At the same time, the transmission device 5 drives the mounting component 601 to move, which allows the slider 702 to move inside the sliding groove 701. This allows the small electric telescopic rod 703 to support the bottom of the mounting component 601, so that the mounting component 601 can stably support the movement of the steel pipe.

[0027] In this invention, during use, the steel pipe is placed on the outer surface of the transmission roller 602. The steel pipe is pushed so that the pressing member 605 penetrates into the steel pipe. At this time, the large electric telescopic rod 604 extends, which brings the bottom of the pressing member 605 into contact with the inner wall of the steel pipe. The pressing of the pressing member 605 on the steel pipe, combined with the contact between the transmission roller 602 and the outer surface of the steel pipe, limits the steel pipe. At the same time, the motor 607 starts, causing the bidirectional threaded rod 608 to rotate, which moves the fixing block 609 toward the inner wall of the steel pipe. This brings the arc-shaped outer surface of the pressing block 610 into contact with the inner wall of the steel pipe, which can subject the steel pipe to lateral pressure, thus ensuring stable limiting of the steel pipe and preventing rotation during steel pipe grinding.

[0028] Furthermore, after the steel pipe is stopped, the lifting device 3 drives the grinding device 4 to move downward, allowing the grinding device 4 to grind the outer surface of the steel pipe. At the same time, the transmission device 5 drives the mounting part 601 to move, which allows the slider 702 to move inside the slide groove 701, thereby allowing the small electric telescopic rod 703 to support the bottom of the mounting part 601, so that the mounting part 601 can stably support the steel pipe and move.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
