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

[0003] The seamless stainless steel pipe of new energy vehicles is a special type of steel pipe, which has a hollow cross-section and seamless periphery. This steel pipe is made of stainless steel material, so it has excellent corrosion resistance and can resist the erosion of various chemical substances.

[0004] Patent CN118287519A discloses a cold rolling forming device for seamless stainless steel pipes, which improves the pretreatment effect of the steel pipes and the cold rolling forming quality. However, when preprocessing the seamless stainless steel pipes, this device can only process the spots and burrs on the outer wall of the seamless stainless steel pipes. During the production of seamless stainless steel pipes, spots and burrs will appear on both the outer wall and the inner wall of the seamless stainless steel pipes. This device cannot process the spots and burrs on the inner wall of the seamless stainless steel pipes. It is necessary to preprocess the inner wall of the seamless stainless steel pipes before processing the outer wall of the seamless stainless steel pipes. The outer wall and the inner wall of the seamless stainless steel pipes cannot be processed simultaneously and need to be processed step by step. There is a lack of synchronism during the processing of seamless stainless steel pipes, resulting in low efficiency and more time consumption.

[0005] Patent CN110576353A discloses an internal grinding device for cold rolled steel pipes. The inner part and both ends of the steel pipes are flexibly ground through grinding convex heads, and then the steel pipes are flexibly positioned through compression springs and telescopic rods, so as to achieve the effect of flexible grinding of cold rolled steel pipes. However, when grinding the steel pipes, this device can only grind the inner wall of the steel pipes and cannot grind the outer wall of the steel pipes. The inner wall and the outer wall of the steel pipes cannot be ground synchronously and need to be processed step by step. There is a lack of synchronism during the grinding of the steel pipes, resulting in low efficiency and more time consumption. Summary of the Invention

[0027] The beneficial effects of the present invention:

[0028] After the positions of the grinding head and the grinding brush are adjusted according to the diameter of the seamless stainless steel pipe in the present invention, the seamless stainless steel pipe is fed between the grinding head and the grinding brush. By starting the driving motor, the driving motor drives the fourth gear to rotate. The rotation of the fourth gear drives the third gear and the second rotating rod to rotate. The rotation of the third gear drives the first rotating rod to rotate. The rotation of the first rotating rod drives the second gear to rotate. The rotation of the second gear drives the outer tooth ring and the adjusting ring to rotate, thereby driving the grinding head to rotate around the adjusting ring. The rotation of the grinding head can grind the outer side of the seamless stainless steel pipe. The rotation of the second rotating rod drives the connecting plate and the grinding brush to rotate. The rotation of the grinding brush can grind the inner wall of the seamless stainless steel pipe. By continuously feeding the seamless stainless steel pipe, different positions of the seamless stainless steel pipe can be ground, and the inner wall and the outside of the seamless stainless steel pipe can be ground simultaneously, improving the synchronism of grinding and the grinding efficiency.

[0029] In the present invention, by starting the first motor, the first motor drives one of the first gears to rotate. During the rotation of one of the first gears, it cooperates with the internal tooth ring to make the other first gears rotate synchronously. The rotation of the first gear drives the rack to move in the first chute, thereby driving the grinding head to move. The position of the grinding head 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, the outside of seamless stainless steel pipes with different outer diameters can be ground.

[0030] In the present invention, by rotating the turning handle, the threaded rod moves in the internal thread sleeve. The movement of the threaded rod will synchronously drive the sleeve and the connecting piece to move. During the movement of the connecting piece, it cooperates with the connecting arm. Under the limiting action of the support rod and the auxiliary ring, it will push or pull the mounting plate. The movement of the mounting plate will drive the grinding brush to move. According to the inner diameter of the seamless stainless steel pipe, the position of the grinding brush can be adjusted by observing the scale. After the position adjustment of the grinding brush is completed, the inner wall of the seamless stainless steel pipe can be ground. The adjustment is simple and convenient, and by adjusting the position of the grinding brush, the inner walls of seamless stainless steel pipes with different inner diameters can be ground.

[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

[0050] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0051] Please refer to Figure 1 - Figure 9 As shown, a cold rolling forming device and process for seamless stainless steel pipes used in new energy vehicles include a bottom plate 1. One end of the upper surface of the bottom plate 1 is provided with a cold rolling mill 8 for cold rolling seamless stainless steel pipes.

[0052] In the middle of the upper surface of the bottom plate 1, a first mounting bracket 11 is connected for installing and supporting the adjusting ring 2.

[0053] In the middle of the first mounting bracket 11, an adjusting ring 2 is provided. The adjusting ring 2 is connected to the first mounting bracket 11 through a bearing, and the middle of the adjusting ring 2 is for passing seamless stainless steel pipes.

[0054] A plurality of racks 21 are arranged in a circumferential array on the inner circumference of the adjusting ring 2. At the position of the rack 21 corresponding to the adjusting ring 2, a first sliding groove 22 is opened. The rack 21 is slidably connected in the first sliding groove 22. The rack 21 is used to adjust the position of the grinding head 23, and the first sliding 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 with a grinding head 23 for grinding the outside of the seamless stainless steel pipe.

[0056] An annular groove 26 is opened in the middle of the adjusting ring 2. The annular groove 26 is used to accommodate the first gear 24 and the internal tooth ring 25.

[0057] A first gear 24 is arranged at the position corresponding to the rack 21 in the annular groove 26. The rack 21 meshes with the first gear 24. The first gear 24 is rotatably connected in the adjusting ring 2. By rotating the first gear 24, the positions of the rack 21 and the grinding head 23 can be adjusted.

[0058] An internal tooth ring 25 is rotatably connected in the annular groove 26. The internal tooth ring 25 meshes with the first gear 24. Through the cooperation of the internal tooth ring 25, after one of the first gears 24 rotates, the rest of the 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 internal tooth ring 25 are meshed alternately outside the first gear 24. By this setting method, the mutual influence between the rack 21 and the internal tooth ring 25 can be avoided.

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

[0061] In specific use, by starting the first motor 241, the first motor 241 drives one of the first gears 24 to rotate. During the rotation of one of the first gears 24, it cooperates with the internal tooth ring 25 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 sliding groove 22, thereby driving the grinding head 23 to move. By adjusting the position of the grinding head 23 according to the outer diameter of the seamless stainless steel pipe, the outside of the seamless stainless steel pipe can be ground. 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 ground.

[0062] A connecting plate 3 is provided in the middle of the adjusting ring 2. The connecting plate 3 is concentric with the adjusting ring 2. By this setting method, 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 accurately correspond to the outside and the inner wall of the seamless stainless steel pipe.

[0063] In the middle of the side of the connecting plate 3 close to the cold rolling mill 8, an internal thread sleeve 34 is connected. A scale 312 is provided on the outside of the internal thread sleeve 34. By observing the scale 312, the position of the adjusting plate 343 moving can be understood.

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

[0065] A positioning ring 33 is connected to the outside of the threaded rod 311 near the turning handle 32. A collar 331 is rotatably connected to the outside of the positioning ring 33. One end of the collar 331 away from the turning handle 32 is connected with a sleeve 34. The sleeve 34 is located outside the internal thread sleeve rod 31. Through the cooperation of the positioning ring 33 and the collar 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 pieces 341 are connected to the outer circumference of the sleeve 34 in an array. Both ends on both sides of the connecting piece 341 are rotatably connected with rotating arms 342. A plurality of corresponding adjusting plates 343 are provided at the positions of the connecting plate 3 corresponding to the connecting pieces 341. One end of the rotating arm 342 away from the connecting piece 341 is connected with the adjusting plate 343. The connecting arm and the adjusting plate 343 cooperate to adjust the position of the grinding brush 348.

[0067] A first movable groove 344 is opened at the 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] Please refer to Figure 7 As shown, symmetrically arranged support rods 345 are respectively connected to the positions of the connecting plate 3 corresponding to both sides of the adjusting plate 343. The connecting plate 3 is located between the support rods 345. The support rods 345 are used to support the adjusting plate 343 and further limit the position of the adjusting plate 343, so that the adjusting plate 343 can only move in the horizontal direction.

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

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

[0071] In specific use, by rotating the rotating handle 32, the threaded rod 311 moves in the internal thread sleeve 34. The movement of the threaded rod 311 will synchronously drive the sleeve 34 and the connecting piece 341 to move. During the movement of the connecting piece 341, in cooperation with the connecting arm, under the limiting action of the support rod 345 and the auxiliary ring 346, the mounting plate 347 will be pushed or pulled. The movement of the mounting plate 347 will drive the grinding brush 348 to move. According to the inner diameter of the seamless stainless steel pipe, by observing the scale 312, the position of the grinding brush 348 can be adjusted. After the position adjustment of the grinding brush 348 is completed, the inner wall of the seamless stainless steel pipe can be ground. The adjustment is simple and convenient. And by adjusting the position of the grinding brush 348, the inner walls of seamless stainless steel pipes with different inner diameters can be ground.

[0072] Please refer to Figure 7 As shown, a wedge block 4 is arranged above the grinding brush 348 corresponding to the mounting plate 347. A second sliding groove 41 is opened at the position of the mounting plate 347 corresponding to the wedge block 4. One side of the mounting plate 347 close to the sleeve 34 is connected with a housing 42 at the position corresponding to the wedge block 4. The wedge block 4 is slidably connected in the second sliding groove 41 and the housing 42. A spring 43 is connected between the wedge block 4 and the housing 42. A dial block 44 is connected above the wedge block 4. A second moving groove 45 is opened at the position of the housing 42 corresponding to the dial block 44. The dial block 44 is slidably connected in the second moving groove 45.

[0073] A chamfer 349 is opened below the grinding brush 348. The chamfer 349 is used in cooperation with the wedge block 4. Through the chamfer 349 below the grinding brush 348, when the grinding brush 348 is installed, the grinding brush 348 can more conveniently press the wedge block 4.

[0074] In specific use, when the mounting plate 347 is installed, the end of the grinding brush 348 with the chamfer 349 is aligned with the mounting plate 347 and inserted. When inserted, the grinding brush 348 will contact the wedge block 4 and press the wedge block 4. After being pressed, the wedge block 4 will slide into the housing 42. During the sliding process of the wedge block 4, the spring 43 will be compressed. The spring 43 will contract and store the restoring force when being compressed. After the grinding brush 348 enters the mounting plate 347 and passes over the wedge block 4, the wedge block 4 loses the block. Under the action of the restoring force of the spring 43, the wedge block 4 will be restored. After the wedge block 4 is restored, 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.

[0076] An outer gear ring 5 is connected to the outer side of the adjusting ring 2, and a second gear 51 is meshed on the upper outer side of the outer gear ring 5. The second gear 51 is connected to the first mounting frame 11 through a bearing, and a first rotating rod 52 is connected to the middle of the side of the second gear 51 away from the cold rolling mill 8, and a third gear 53 is connected to the end of the first rotating rod 52 away from the second gear 51, and a fourth gear 54 is meshed below the third gear 53. A second rotating rod 55 is connected to the middle of the side of the fourth gear 54 close to the connecting plate 3, and an end of the second rotating rod 55 away from the fourth gear 54 is connected to the connecting plate 3, and a second mounting frame 56 is connected to the position of the third gear 53 and the fourth gear 54 on the upper surface of the bottom plate 1. The third gear 53 and the fourth gear 54 are connected to the second mounting frame 56 through a bearing.

[0077] A driving motor 57 is connected to the middle of the side of the fourth gear 54 away from the second rotating rod 55, and a fixing plate 58 is connected to the second mounting frame 56 corresponding to the position of the driving motor 57. The driving motor 57 is mounted on the fixing plate 58 and is used to drive the fourth gear 54 to rotate.

[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 should be noted here that: through the cooperation of the third gear 53 and the fourth gear 54, when the grinding head 23 and the grinding brush 348 rotate, their directions are opposite to each other. By this setting method, the rotational force generated on the seamless stainless steel pipe during grinding can be reduced, avoiding the rotation of the seamless stainless steel pipe, so that the seamless stainless steel pipe can be ground quickly and evenly, and the dead corners during grinding can be reduced, enabling both the inner wall and the outer wall to be fully ground, thus improving the overall grinding efficiency.

[0080] Above the bottom plate 1, a first support plate 6 is arranged corresponding to the position between the first mounting frame 11 and the cold rolling mill 8. A uniformly arranged first conveyor roller 61 is rotatably connected inside the first support plate 6 for assisting in conveying the seamless stainless steel pipe.

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

[0082] A first U-shaped plate 63 is slidably connected inside the first support plate 6. The first U-shaped plate 63 is composed of two vertical plates and a horizontal plate. Symmetrically arranged first moving grooves 64 are formed in the first support plate 6 corresponding to the vertical plates. The first U-shaped plate 63 is slidably connected in the first moving grooves 64. A first reciprocating lead screw 65 is rotatably connected in one of the first moving grooves 64. One of the vertical plates is threadedly connected to the first reciprocating lead screw 65. The end of the first reciprocating lead screw 65 away from the adjusting ring 2 penetrates the first support plate 6 and is connected to a 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 above the mutually remote sides of the two vertical plates. The pneumatic shafts of the second cylinders 68 penetrate the vertical plates and are connected to first clamping plates 69.

[0083] Above the bottom plate 1, a second support plate 7 is arranged corresponding to the position between the first mounting frame 11 and the second mounting frame 56. A uniformly arranged second conveyor roller 71 is rotatably connected inside 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. By this setting method, on the premise of being able to convey the seamless stainless steel pipe, a space for placing the seamless stainless steel pipe can be reserved for the first mounting frame 11 to prevent the first clamping plate 69 from affecting the seamless stainless steel pipe.

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

[0086] A second U-shaped plate 73 is slidably connected inside the second support plate 7. The second U-shaped plate 73 is composed of two vertical plates and a horizontal plate. Symmetrically arranged second moving grooves 74 are formed in the second support plate 7 at positions corresponding to the vertical plates. The second U-shaped plate 73 is slidably connected inside the second moving grooves 74. A second reciprocating lead screw 75 is rotatably connected inside one of the second moving grooves 74. One of the vertical plates is threadedly connected to the second reciprocating lead screw 75. The end of the second reciprocating lead screw 75 away from the adjusting ring 2 penetrates through the second support plate 7 and is connected to a third motor 76 fixed to the side of the second support plate 7. A second positioning rod 77 is connected inside the other second moving groove 74. The other vertical plate is slidably connected to the second positioning rod 77. Fourth cylinders 78 are respectively connected above the mutually remote sides of the two vertical plates. The pneumatic shafts of the fourth cylinders 78 penetrate through the vertical plates and are connected to second clamping plates 79.

[0087] It should be noted that: As shown in Figure 3 , section A is the initial position of the first clamping plate 69; the distance from section A to section B is the reserved length for placing the seamless stainless steel pipe, to prevent the first clamp and the second clamp from 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 capable of grinding the seamless stainless steel pipe is the distance from section B to section C; section C is the position where the first clamping plate 69 is closest to the grinding head 23 and the grinding brush 348 after moving; the distance from section C to section D is the position where the seamless stainless steel pipe cannot be ground after the first clamping plate 69 conveys the seamless stainless steel pipe; section E is the position where the second clamping plate 79 is closest to the grinding head 23 and the grinding brush 348 after moving; the distance from section C to section F is equal to the distance from section B to section C, both being the longest length capable of grinding 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. By conveying the seamless stainless steel pipe with the second clamping plate 79, the position that cannot be ground when the first clamping plate 69 conveys the seamless stainless steel pipe can be ground off, enabling the seamless stainless steel pipe to be comprehensively ground.

[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 section C 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 make the grinding head 23 and the grinding brush 348 rotate. 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 the placement is completed, 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 lead screw 65. When the first clamping plate 69 senses the seamless stainless steel pipe, the second cylinder 68 will be started to make the first clamping plate 69 clamp the seamless stainless steel pipe. After clamping, the first clamping plate 69 conveys the seamless stainless steel pipe, and the seamless stainless steel pipe will be ground during the conveying process. When the first clamping plate 69 moves to section C, it can no longer convey the seamless stainless steel pipe. The second motor 66 will stop rotating to make the first clamping plate 69 stay at the position of section C and the second cylinder 68 will be started again to make the first clamping plate 69 move 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 correspond to the second clamping plate 79. When the second clamping plate 79 senses the seamless stainless steel pipe, the fourth cylinder 78 will be started to make the second clamping plate 79 clamp 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 through the cooperation of the second reciprocating lead screw 75, driving the seamless stainless steel pipe to be conveyed to the position of section G first. After the seamless stainless steel pipe is conveyed to section G, the seamless stainless steel pipe is fully ground. After the grinding is completed, the second clamping plate 79 will continue to convey the seamless stainless steel pipe and will move to section E. After the second clamping plate 79 moves to section E, it can no longer convey the seamless stainless steel pipe. The fourth cylinder 78 will be started to make the second clamping plate 79 move away from the seamless stainless steel pipe. At this time, the first cylinder 62 will be started to make the first clamping plate 69 clamp the seamless stainless steel pipe again, and the second motor 66 will be started to make the first clamping plate 69 convey the seamless stainless steel pipe and the first clamping plate 69 will move to section A. After the first clamping plate 69 moves to section A, it will send the seamless stainless steel pipe into the cold rolling mill 8 for cold rolling processing. After the first clamping plate 69 moves to section A, that is, the first clamping plate 69 completes a process, the second motor 66 will stop running to make the first clamping plate 69 stay at section A waiting for the conveyance of the next seamless stainless steel pipe. After the second clamping plate 79 moves to section E, it will continue to move to the starting adjustment position, that is, the second clamping plate 79 completes a process, and the third motor 76 will stop running,Keep the second clamping plate 79 at the starting adjustment position to wait for the transfer of the next seamless stainless steel pipe. After the next seamless stainless steel pipe is placed on the first support plate 6, restart the second motor 66 and the third motor 76 to polish the next seamless stainless steel pipe. The operation is simple and convenient. In one polishing process, the seamless stainless steel pipe can be polished twice, and the seamless stainless steel pipe can be polished comprehensively, improving the polishing efficiency and quality. It can polish seamless stainless steel pipes with different diameters and lengths, improving the adaptability.

[0089] The cold rolling forming process includes the following steps:

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

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

[0092] S3: Adjust the position of the second clamping plate 79 according to the length of the seamless stainless steel pipe.

[0093] S4: Start the driving motor 57 to rotate the grinding head 23 and the grinding brush 348.

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

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

[0096] S7: Transfer the seamless stainless steel pipe into the cold rolling mill 8 for cold rolling processing.
