Description

Technical Field

[0001] This utility model relates to a grinding equipment, specifically a polishing and grinding device for welded pipe rolls. Background Technology

[0002] Welded pipes are widely used metal pipes in modern industry, and their specifications are diverse. The specifications of the rolling mills used to produce welded pipes are even more numerous. One specification of welded pipe usually corresponds to dozens of rolling mills. After continuous use, the rolling mills will cause various problems on the surface of the welded pipe, such as dents, bumps, black rust, and zinc slag. In order to ensure the qualification rate of welded pipe production, the rolling mills need to be polished and ground. However, polishing and grinding of welded pipe rolling mills requires the use of specific fixtures and equipment. For some pipeline manufacturers without such equipment, the rolling mills need to be sent back to the factory for repair or replacement, which is very costly and has a very long repair cycle.

[0003] Currently, a utility model patent with publication number CN222831385U discloses a polishing machine for cold rolling rolls, including an L-shaped frame. A support and lifting assembly is provided on the inner side of the L-shaped frame. The support and lifting assembly includes an arc-shaped support plate. A fixing clamp is fixedly installed on the lower outer surface of the arc-shaped support plate. A support block is rotatably connected to the inner surface of the fixing clamp. A sliding clamp is rotatably connected to the outer surface of one end of the support block. A positive and negative lead screw is threadedly connected to the lower inner wall of the sliding clamp. A rack is fixedly installed in the middle of the outer surface of the positive and negative lead screw. A threaded rod is engaged on the outer surface of the rack. A motor is fixedly installed on the outer surface of one end of the threaded rod. By using the support and lifting assembly, the motor is started, driving the threaded rod to rotate, thereby driving the positive and negative lead screw to rotate, which in turn causes the two sliding clamps to slide relative to each other, allowing the support block to support the arc-shaped support plate. This structure reduces the danger of the polishing machine, facilitates the fixing of the cold rolling rolls, and improves the working efficiency of the polishing machine.

[0004] As can be seen from the above-disclosed technical content, as existing technology, the utility model with announcement number CN222831385U completes the automatic loading, unloading and grinding of the rolls through a series of complex mechanical structures. Although it effectively improves work efficiency, the overall structure is extremely complex and involves a large number of automated control structures, resulting in high overall costs and making it unsuitable for large-scale promotion.

[0019] The polishing and grinding device for welded pipe rolls of this utility model is described below with reference to the accompanying drawings.

[0020] In Embodiment 1 of this application, as Figures 1 to 3 As shown, the welding pipe roll polishing and grinding device (hereinafter referred to as "the present invention") includes an operating table 1. A motor 5 is fixedly mounted on the upper part of the operating table 1 via a bracket. A slide rail 2 is provided on the surface of the operating table 1 opposite to the motor 5. A roll clamping device sliding table 3 moves back and forth on the slide rail 2. The two ends of the roll clamping device 4 are respectively connected to the roll clamping device sliding table 3 and the motor 5. The rotating shaft 41 of the roll clamping device 4 is fixedly connected to the output shaft of the motor 5. A cone head 42 is fixedly mounted on the rotating shaft 41. The bearing seat 45 of the roll clamping device 4 is fixedly mounted on the roll clamp. An adjusting shaft 44 is movably mounted on a bearing seat 45 on a sliding table 3 of the holding device. A second cone head 43 is sleeved on the adjusting shaft 44. A control unit 6 is mounted on the operating table 1 via a bracket. Multiple grinding component limiting slots 8 are evenly spaced on one side of the operating table 1, and grinding component limiting protrusions 9 are fixedly installed near the grinding component limiting slots 8. The grinding component 7 is mounted on the operating table 1 through the grinding component limiting slots 8 and the grinding component limiting protrusions 9. The adjusting shaft 44 is a central shaft with an outer sleeve. The end of the sleeve abuts against the second cone head 43, and the central shaft is inserted into a pre-set concave hole at the end of the first cone head 42. Figure 5As shown, by replacing the sleeve of the corresponding length, the corresponding size of the roll 46 can be clamped.

[0021] A polishing machine for cold rolling rolls (hereinafter referred to as "the patent") with utility model announcement number CN222831385U is disclosed. The patent completes the automatic loading, unloading and polishing of the rolls through a series of complex mechanical structures. Although it effectively improves work efficiency, the overall structure is extremely complex and involves a large number of automated control structures, resulting in high overall costs and hindering large-scale promotion. In contrast, the present invention uses a roll clamping device 4 to clamp the rolls from both sides, ensuring that the rolls and the roll clamping device 4 are on the same axis, thus ensuring polishing accuracy. The motor 5 drives the rolls to rotate rapidly, and then the polishing head 78 is manually controlled to polish the rolls. The overall structure is simple, and the rolls can be polished quickly and conveniently, effectively reducing production costs.

[0022] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 4 As shown, the grinding assembly 7 includes a fixed clamping plate 71, a grinding base 72, a raised groove 73, a stand 74, a control tube 75, a pin hole 76, a telescopic tube 77, and a grinding head 78. The fixed clamping plate 71 of the grinding assembly 7 is connected to the grinding base 72 by screws. The raised groove 73 is opened on the lower surface of the grinding base 72. The grinding assembly limiting raised strip 9 is embedded in the raised groove 73. The screws of the fixed clamping plate 71 are engaged with the grinding assembly limiting through groove 8. The stand 74 is fixedly installed on the upper part of the grinding base 72. The top of the stand 74 is movably connected to the middle of the control tube 75. One end of the control tube 75 is a handle, and the other end is sleeved with the telescopic tube 77. The grinding head 78 is fixedly installed at the end of the telescopic tube 77. Pin holes 76 are set at equal intervals on the control tube 75 and the telescopic tube 77, and pins are inserted.

[0023] To further optimize the working efficiency of this application, and to enable the fixing clamp 71 to clamp the operating table 1 via the grinding base 72 by adjusting the screws on it, the fixing clamp 71 is equipped with screws using bearings and washers, allowing the screws to rotate without dislodging from the fixing clamp 71. To speed up the grinding process, a grinding wheel is mounted on the end of the telescopic tube 77 via a bracket. If further cost reduction is required, the surface of the grinding head 78 is covered with sandpaper, and only the sandpaper fixing clamp 71 needs to be replaced during maintenance.

[0024] When in use, install the welding pipe roll polishing and grinding device and connect the corresponding lines, and the equipment can be put into use.

[0025] When this utility model is used, its specific operation is as follows:

[0026] In use, loosen the screws on the lower part of the sliding table 3 of the roll clamping device that abut against the surface of the operating table 1. Then, manually control the sliding table 3 of the roll clamping device to open along the slide rail 2, so that the end of the central shaft of the adjusting shaft 44 of the roll clamping device 4 disengages from the pre-set concave hole of the cone head 42. Continue to change the type of roll 46 and replace the corresponding sleeve on the adjusting shaft 44. Reinstall the cone head 43. Then, place the roll 46 on the central shaft of the adjusting shaft 44, and let the end of the central shaft of the adjusting shaft 44 be reinserted into the pre-set concave hole of the cone head 42. As the sliding table 3 of the roll clamping device continues to push, the cone head 42 and the cone head 43 on both sides of the roll 46... 3. Gradually reduce the gap to clamp the roll 46, and gradually make the axis of the roll 46 coincide with the axis of the roll clamping device 4. Then, loosen the screws of the fixing plate 71 to increase the gap between the fixing plate 71 and the grinding base 72, so that the convex groove 73 can disengage from the grinding component limiting convex strip 9 and the grinding component 7 can be removed. Then, adjust the position of the grinding component 7 to a suitable position, and re-insert the screws of the fixing plate 71 into the corresponding grinding component limiting through groove 8, so that the convex groove 73 is locked on the grinding component limiting convex strip 9. Tighten the screws of the fixing plate 71 again so that the fixing plate 71 and the grinding base 72 clamp the operating table 1. Next, remove the pin from the pin hole 76 on the control tube 75, adjust the length of the telescopic tube 77 so that the grinding head 78 can just fit against the surface of the roll 46, and then reinsert the pin. At this point, grinding can begin. During grinding, the motor 5 is started via the control unit 6. The motor 5 drives the rotating shaft 41, cone head 1 42, cone head 2 43, adjusting shaft 44, and roller 46 of the roller clamping device 4 to rotate at high speed in the bearing seat 45. The operator presses down the handle of the control tube 75 to bring the grinding head 78 into contact with the surface of the roller 46 for grinding. After grinding is completed, the sliding table 3 of the roller clamping device is retracted, and the roller 46 can be removed.

[0027] In summary, the welded pipe roll polishing and grinding device of this utility model clamps the roll from both sides through the roll clamping device 4, ensuring that the roll and the roll clamping device 4 are on the same axis, thus ensuring grinding accuracy. The motor 5 drives the roll to rotate quickly, and then the grinding head 78 is manually controlled to grind the roll. The overall structure is simple, and the roll can be ground quickly and conveniently, which can effectively reduce production costs.
