Description

Technical Field

[0001] The present invention belongs to the technical field of stainless steel cold rolling, and specifically relates to a cold rolling forming device and process for a seamless stainless steel pipe for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source. The emergence of such vehicles aims to solve the environmental and resource problems faced by traditional fuel vehicles, and also to meet people's demand for more energy-saving, environmentally friendly and sustainable travel.

[0003] Seamless stainless steel pipes for new energy vehicles are a special type of steel pipe with a hollow cross-section and seamless periphery. Made of stainless steel, this steel pipe has excellent corrosion resistance and can resist the erosion of a variety of chemicals.

[0004] Patent CN118287519A discloses a cold rolling forming device for seamless stainless steel pipes, which improves the pretreatment effect of steel pipes and the quality of cold rolling forming. However, when pretreating seamless stainless steel pipes, the device can only process spots and burrs on the outer wall of the seamless stainless steel pipes. When the seamless stainless steel pipes are produced, spots and burrs will appear on both the outer wall and the inner wall of the seamless stainless steel pipes. The device cannot process the spots and burrs on the inner wall of the seamless stainless steel pipes. It is necessary to process the inner wall of the seamless stainless steel pipe before processing the outer wall of the seamless stainless steel pipe. The outer wall and the inner wall of the seamless stainless steel pipe cannot be processed at the same time, and need to be processed in steps. There is a lack of synchronization when processing the seamless stainless steel pipes, and the efficiency is low, which requires more time.

[0005] Patent CN110576353A discloses an internal grinding device for cold-rolled steel pipes, which flexibly grinds the inside and both ends of the steel pipe through a grinding boss, and then flexibly positions the steel pipe through a compression spring and a telescopic rod, thereby achieving the effect of flexible grinding of the cold-rolled steel pipe. However, when grinding the steel pipe, the device can only grind the inner wall of the steel pipe, but cannot grind the outer wall of the steel pipe, and cannot grind the inner and outer walls of the steel pipe synchronously, and needs to be processed in steps. There is a lack of synchronization when grinding the steel pipe, and the efficiency is low, which requires more time. Summary of the invention

The adjustment is simple and convenient, and the inner wall of seamless stainless steel pipes with different internal diameters can be polished by adjusting the position of the grinding brush.

[0031] When installing the mounting plate, align the chamfered end of the grinding brush with the mounting plate and insert it. When inserting, the grinding brush will contact the wedge block and squeeze the wedge block. After being squeezed, the wedge block will slide into the shell. During the sliding process, the wedge block will squeeze the spring. The spring will shrink and store the restoring force when being squeezed. After the grinding brush enters the mounting plate and passes over the wedge block, the wedge block loses its obstruction. Under the action of the spring restoring force, the wedge block will recover. After the wedge block recovers, the grinding brush will be between the wedge block and the mounting plate, so that the grinding brush is fixed and will not fall off the mounting plate. When the grinding brush needs to be removed, the grinding brush can be taken out of the mounting plate by moving the dial block to make the wedge block away from the grinding brush. It is convenient to install and remove the grinding brush, and the efficiency of installation and removal can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] A plurality of racks 21 are arranged in an inner circumferential array of the adjusting ring 2, and a first slide groove 22 is opened at the position of the adjusting ring 2 corresponding to the rack 21. The rack 21 is slidably connected in the first slide groove 22. The rack 21 is used to adjust the position of the grinding head 23, and the first slide groove 22 is used to limit the position of the rack 21.

[0055] One end of the rack 21 close to the middle of the adjusting ring 2 is connected to a grinding head 23 for grinding the outside of the seamless stainless steel pipe.

[0056] An annular groove 26 is formed in the middle of the adjusting ring 2 , and the annular groove 26 is used to receive the first gear 24 and the inner gear ring 25 .

[0057] A first gear 24 is provided in the annular groove 26 at a position corresponding to the rack 21 , the rack 21 is meshed with the first gear 24 , and the first gear 24 is rotatably connected in the adjustment ring 2 , and the positions of the rack 21 and the grinding head 23 can be adjusted by rotating the first gear 24 .

[0058] An inner gear ring 25 is rotatably connected in the annular groove 26 , and the inner gear ring 25 meshes with the first gear 24 . Through the cooperation of the inner gear ring 25 , after one of the first gears 24 rotates, the other first gears 24 can be rotated synchronously, so that the positions of multiple grinding heads 23 can be adjusted synchronously.

[0059] The rack 21 and the inner gear ring 25 are meshed in an alternating manner on the outer side of the first gear 24 . This arrangement can avoid mutual interference between the rack 21 and the inner gear ring 25 .

[0060] A first motor 241 is installed at a position corresponding to one of the first gears 24 on one side of the adjustment ring 2 close to the cold rolling mill 8. The driving shaft of the first motor 241 passes through the adjustment ring 2 and is connected to one of the first gears 24. The first motor 241 is used to drive one of the first gears 24 to rotate.

[0061] During specific use, by starting the first motor 241, the first motor 241 drives one of the first gears 24 to rotate, and one of the first gears 24 cooperates with the inner gear ring 25 during the rotation process to make the other first gears 24 rotate synchronously. The rotation of the first gear 24 drives the rack 21 to move in the first slide groove 22, thereby driving the grinding head 23 to move. The position of the grinding head 23 can be adjusted according to the outer diameter of the seamless stainless steel pipe to grind the outside of the seamless stainless steel pipe. The adjustment is simple and convenient, and by adjusting the position of the grinding head 23, the outside of seamless stainless steel pipes with different outer diameters can be polished.

[0062] A connecting plate 3 is provided in the middle of the adjusting ring 2, and the connecting plate 3 is arranged cocentrically with the adjusting ring 2. Through this arrangement, after the positions of the grinding head 23 and the grinding brush 348 are adjusted, the grinding head 23 and the grinding brush 348 can be made to accurately correspond to the outer and inner walls of the seamless stainless steel pipe.

[0063] An internal threaded sleeve 34 is connected to the middle of the connecting plate 3 close to the cold rolling mill 8 , and a scale 312 is arranged on the outside of the internal threaded sleeve 34 . By observing the scale 312 , the moving position of the adjustment plate 343 can be understood.

[0064] The internal thread of the internal thread sleeve 34 is connected to a threaded rod 311 , and one end of the threaded rod 311 away from the connecting plate 3 is connected to a turning handle 32 . The position of the threaded rod 311 can be adjusted by rotating the turning handle 32 .

[0065] A positioning ring 33 is connected to the outer side of one end of the threaded rod 311 close to the turning handle 32, and a sleeve 331 is rotatably connected to the outer side of the positioning ring 33. The end of the sleeve 331 away from the turning handle 32 is connected to a sleeve 34. The sleeve 34 is located outside the internally threaded sleeve 31. Through the cooperation between the positioning ring 33 and the sleeve 331, after the position of the threaded rod 311 is adjusted, the position of the sleeve 34 will be adjusted synchronously.

[0066] A plurality of connecting plates 341 are connected to a circular array on the outer side of the sleeve 34, and both ends on both sides of the connecting plate 341 are rotatably connected to rotating arms 342. A plurality of corresponding adjustment plates 343 are arranged at the positions of the connecting plate 3 corresponding to the connecting plates 341. One end of the rotating arm 342 away from the connecting plate 341 is connected to the adjustment plate 343, and the connecting arm cooperates with the adjustment plate 343 to adjust the position of the grinding brush 348.

[0067] A first movable groove 344 is formed at a position of the connecting plate 3 corresponding to the adjusting plate 343 . The adjusting plate 343 is slidably connected in the first movable groove 344 . The first movable groove 344 is used to limit the moving position of the adjusting plate 343 .

[0068] See also Figure 7 As shown, the positions of the connecting plates 3 on both sides of the adjustment plate 343 are respectively connected with symmetrically arranged support rods 345, and the connecting plates 3 are located between the support rods 345. The support rods 345 are used to support the adjustment plate 343 and further limit the position of the adjustment plate 343 so that the adjustment plate 343 can only move in the horizontal direction.

[0069] An auxiliary ring 346 is rotatably connected to the outer side of the support rod 345 , and the auxiliary ring 346 is used to reduce the friction between the support rod 345 and the connecting plate 3 , so that the adjustment plate 343 can move more smoothly.

[0070] A mounting plate 347 is connected to the side of the adjustment plate 343 away from the sleeve 34 , and a grinding brush 348 is installed in the mounting plate 347 . The grinding brush 348 is used to grind the inner wall of the seamless stainless steel pipe.

[0071] During specific use, the threaded rod 311 is moved in the internal threaded sleeve 34 by rotating the handle 32. The movement of the threaded rod 311 will synchronously drive the sleeve 34 and the connecting piece 341 to move. The connecting piece 341 cooperates with the connecting arm during the movement, and under the action of the support rod 345 and the auxiliary ring 346, it will push or pull the mounting plate 347. The movement of the mounting plate 347 will drive the grinding brush 348 to move.

[0073] A chamfer 349 is provided below the grinding brush 348 , and the chamfer 349 is used in conjunction with the wedge block 4 . Through the chamfer 349 below the grinding brush 348 , the grinding brush 348 can more conveniently squeeze the wedge block 4 when the grinding brush 348 is installed.

[0074] In specific use, when installing the mounting plate 347, align the end of the grinding brush 348 with the chamfer 349 with the mounting plate 347 and insert it. When inserting, the grinding brush 348 will contact the wedge block 4 and squeeze the wedge block 4. After being squeezed, the wedge block 4 will slide into the housing 42. During the sliding process, the wedge block 4 will squeeze the spring 43. The spring 43 will shrink and store the restoring force when being squeezed. After the grinding brush 348 enters the mounting plate 347 and passes over the wedge block 4, the wedge block 4 loses its obstruction. Under the action of the restoring force of the spring 43, the wedge block 4 will recover. After the wedge block 4 recovers, the grinding brush 348 will be between the wedge block 4 and the mounting plate 347, so that the grinding brush 348 is fixed and will not fall off from the mounting plate 347.

[0075] When the grinding brush 348 needs to be removed, the grinding brush 348 can be taken out from the mounting plate 347 by moving the shift block 44 to move the wedge block 4 away from the grinding brush 348. This makes it more convenient to install and remove the grinding brush 348, and can improve the efficiency of installation and removal.

[0078] In specific use, after the positions of the grinding head 23 and the grinding brush 348 are adjusted according to the diameter of the seamless stainless steel pipe, the seamless stainless steel pipe is sent between the grinding head 23 and the grinding brush 348, and the driving motor 57 is started. The driving motor 57 drives the fourth gear 54 to rotate, and the rotation of the fourth gear 54 drives the third gear 53 and the second rotating rod 55 to rotate. The rotation of the third gear 53 drives the first rotating rod 52 to rotate, and the rotation of the first rotating rod 52 drives the second gear 51 to rotate. The rotation of the second gear 51 drives the outer gear ring 5 and the adjusting ring 2 to rotate, thereby driving the grinding head 23 to rotate with the adjusting ring 2 as the center. The rotation of the grinding head 23 can grind the outer side of the seamless stainless steel pipe, and the rotation of the second rotating rod 55 drives the connecting plate 3 and the grinding brush 348 to rotate. The rotation of the grinding brush 348 can grind the inner wall of the seamless stainless steel pipe. By continuously transmitting the seamless stainless steel pipe, different positions of the seamless stainless steel pipe can be grinded, and the inner wall and the outer part of the seamless stainless steel pipe can be grinded simultaneously, thereby improving the synchronization of grinding and improving the grinding efficiency.

[0079] It is worth noting here that: through the cooperation of the third gear 53 and the fourth gear 54, the directions of the grinding head 23 and the grinding brush 348 are opposite to each other when they rotate. This setting method can reduce the rotational force generated on the seamless stainless steel pipe during the grinding process, and avoid the rotation of the seamless stainless steel pipe, so that the seamless stainless steel pipe can be ground quickly and evenly, and the dead angle in the grinding process can be reduced, so that both the inner wall and the outer wall can be fully ground, thereby improving the overall grinding efficiency.

[0080] A first support plate 6 is provided above the bottom plate 1 at a position corresponding to between the first mounting frame 11 and the cold rolling mill 8. The first support plate 6 is rotatably connected with uniformly arranged first conveying rollers 61 for assisting in conveying the seamless stainless steel pipe.

[0081] Positions on the upper surface of the bottom plate 1 corresponding to the two ends of the first support plate 6 are respectively connected to first cylinders 62 , and the first cylinders 62 are used to lift the first support plate 6 .

[0082] A first U-shaped plate 63 is slidably connected in the first support plate 6. The first U-shaped plate 63 is composed of two vertical plates and a horizontal plate. A symmetrically arranged first moving groove 64 is opened at the position of the first support plate 6 corresponding to the vertical plate. The first U-shaped plate 63 is slidably connected in the first moving groove 64. A first reciprocating screw rod 65 is rotatably connected in one of the first moving grooves 64. One of the vertical plates is threadedly connected to the first reciprocating screw rod 65. One end of the first reciprocating screw rod 65 away from the adjusting ring 2 passes through the first support plate 6 and is connected to the second motor 66 fixed to the side of the first support plate 6. A first positioning rod 67 is connected in the other first moving groove 64. The other vertical plate is slidably connected to the first positioning rod 67. Second cylinders 68 are respectively connected to the upper sides of the two vertical plates away from each other. The pneumatic shaft of the second cylinder 68 passes through the vertical plate and is connected to the first clamping plate 69.

[0083] A second support plate 7 is disposed above the bottom plate 1 at a position corresponding to between the first mounting frame 11 and the second mounting frame 56 , and evenly arranged second conveying rollers 71 are rotatably connected in the second support plate 7 for assisting in conveying the seamless stainless steel pipe.

[0084] The length of the second mounting frame 56 is shorter than that of the first mounting frame 11. With this arrangement, while being able to convey the seamless stainless steel pipe, space can be reserved for the first mounting frame 11 to place the seamless stainless steel pipe, thereby preventing the first clamping plate 69 from affecting the seamless stainless steel pipe.

[0085] Positions on the upper surface of the bottom plate 1 corresponding to the two ends of the second support plate 7 are respectively connected to third cylinders 72 , and the third cylinders 72 are used to lift the second support plate 7 .

[0086] A second U-shaped plate 73 is slidably connected in the second supporting plate 7. The second U-shaped plate 73 is composed of two vertical plates and a horizontal plate. A symmetrically arranged second movable groove 74 is opened at the position of the second supporting plate 7 corresponding to the vertical plate. The second U-shaped plate 73 is slidably connected in the second movable groove 74. A second reciprocating screw rod 75 is rotatably connected in one of the second movable grooves 74. One of the vertical plates is threadedly connected to the second reciprocating screw rod 75. One end of the second reciprocating screw rod 75 away from the adjusting ring 2 passes through the second supporting plate 7 and is connected to the third motor 76 fixed to the side of the second supporting plate 7. A second positioning rod 77 is connected in the other second movable groove 74. The other vertical plate is slidably connected to the second positioning rod 77. Fourth cylinders 78 are respectively connected to the upper sides of the two vertical plates away from each other. The pneumatic shaft of the fourth cylinder 78 passes through the vertical plate and is connected to the second clamping plate 79.

[0087] It is worth noting that: according to Figure 3 As shown, section A is the initial position of the first clamp 69; the distance from section A to section B is the reserved length for placing the seamless stainless steel pipe, so as to avoid the first clamp and the second clamp affecting the seamless stainless steel pipe when placing the seamless stainless steel pipe; the distance from section B to section C is the distance for placing the seamless stainless steel pipe, that is, the longest length of the seamless stainless steel pipe that can be polished is the distance from section B to section C; section C is the position closest to the polishing head 23 and the polishing brush 348 after the first clamp 69 moves; the distance from section C to section D is the distance between the first clamp 69 and the polishing head 23 and the polishing brush 348; The position of the seamless stainless steel pipe that cannot be polished after being conveyed; Section E is the position closest to the polishing head 23 and the polishing brush 348 after the second clamping plate 79 moves; the distance from Section C to Section F is equal to the distance from Section B to Section C, both of which are the longest lengths that can be used to polish the seamless stainless steel pipe; the distance from the second clamping plate 79 to Section G is greater than the distance from Section C to Section D. Through the conveyance of the seamless stainless steel pipe by the second clamping plate 79, the position of the seamless stainless steel pipe that cannot be polished when the first clamping plate 69 is conveyed can be polished away, so that the seamless stainless steel pipe can be fully polished.

[0088] Working principle: According to the diameter of the seamless stainless steel pipe, the positions of the grinding head 23 and the grinding brush 348 are adjusted. After the adjustment is completed, the first support plate 6 and the second support plate 7 are adjusted by driving the first cylinder 62 and the third cylinder 72, so that the first conveying roller and the second conveying roller correspond to the grinding head 23. After the adjustment of the first support plate 6 and the second support plate 7 is completed, the third motor 76 is started to adjust the position of the second clamping plate 79 so that the distance from the second clamping plate 79 to the C section is equal to the distance of the seamless stainless steel pipe. After the position adjustment of the second clamping plate 79 is completed, the driving motor 57 is started to rotate the grinding head 23 and the grinding brush 348. After the grinding head 23 and the grinding brush 348 rotate, the seamless stainless steel pipe is placed in the B to C area of ​​the first support plate 6. After completion, the second motor 66 and the third motor 76 are started. The second motor 66 moves the first clamping plate 69 to the position from section B to section C through the cooperation of the first reciprocating screw rod 65. When the first clamping plate 69 senses the seamless stainless steel pipe, the second cylinder 68 is started to make the first clamping plate 69 clamp the seamless stainless steel pipe. After clamping, the first clamping plate 69 transmits the seamless stainless steel pipe, and the seamless stainless steel pipe is polished during the transmission process. When the first clamping plate 69 moves to the position of section C, the seamless stainless steel pipe cannot be further transmitted. The second motor 66 stops rotating to make the first clamping plate 69 stay at the position of section C and the second cylinder 68 is started again to make the first clamping plate 69 away from the seamless stainless steel pipe. At this time, the end of the seamless stainless steel pipe away from the first clamping plate 69 will contact with the second cylinder 68. The second clamping plate 79 corresponds to the fourth cylinder 78. When the second clamping plate 79 senses the seamless stainless steel pipe, the fourth cylinder 78 will start, so that the second clamping plate 79 clamps the seamless stainless steel pipe. After the second clamping plate 79 clamps the seamless stainless steel pipe, the third motor 76 will rotate (before the second clamping plate 79 clamps the seamless stainless steel pipe, the third motor 76 will not rotate), and the third motor 76 will convey the seamless stainless steel pipe with the cooperation of the second reciprocating screw 75, driving the seamless stainless steel pipe to be conveyed to the position of the G section first. After the seamless stainless steel pipe is conveyed to the G section, the seamless stainless steel pipe is fully polished. After the polishing is completed, the second clamping plate 79 will continue to convey the seamless stainless steel pipe and move to the E section. After the second clamping plate 79 moves to the E section, it can no longer continue to convey the seamless stainless steel pipe. The fourth cylinder 78 The second plywood 79 will start to move away from the seamless stainless steel pipe. At this time, the first cylinder 62 will start to make the first plywood 69 clamp the seamless stainless steel pipe again, and the second motor 66 will start to make the first plywood 69 convey the seamless stainless steel pipe and the first plywood 69 will move to section A. After the first plywood 69 moves to section A, the seamless stainless steel pipe will be sent to the cold rolling mill 8 for cold rolling processing. After the first plywood 69 moves to section A, that is, the first plywood 69 completes a process, the second motor 66 will stop running, so that the first plywood 69 stays in section A waiting for the next seamless stainless steel pipe to be conveyed. After the second plywood 79 moves to section E, it will continue to move to the position where the adjustment starts, that is, the second plywood 79 completes a process, and the third motor 76 will stop running.The second clamping plate 79 is stopped at the start adjustment position to wait for the next seamless stainless steel pipe to be delivered. After the next seamless stainless steel pipe is placed on the first support plate 6, the second motor 66 and the third motor 76 are restarted to grind the next seamless stainless steel pipe. The operation is simple and convenient. The seamless stainless steel pipe can be grinded twice in one grinding process. The seamless stainless steel pipe can be fully grinded, which improves the grinding efficiency and grinding quality. It can grind seamless stainless steel pipes of different diameters and lengths, and improves adaptability.

[0090] S1: Adjust the positions of the grinding head 23 and the grinding brush 348.

[0091] S2: adjusting the heights of the first support plate 6 and the second support plate 7 according to the diameter of the seamless stainless steel pipe.

[0094] S5: placing the seamless stainless steel pipe on the first support plate 6 .

[0095] S6: Start the second motor 66 and the third motor 76, and with the cooperation of the first reciprocating screw 65 and the second reciprocating screw 75, the seamless stainless steel pipe is clamped and transferred by the first clamping plate 69 and the second clamping plate 79 to grind the seamless stainless steel pipe.

[0096] S7: The seamless stainless steel pipe is transferred to the cold rolling mill 8 for cold rolling.
