Description

Technical Field

[0001] The invention relates to the technical field of stainless steel pipe guiding and straightening, and in particular to a guiding straightening device and method based on a stainless steel pipe. Background Art

[0002] Stainless steel pipe is a hollow long round steel material, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. In addition, when the bending and torsional strengths are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in furniture and kitchen utensils.

[0003] The stainless steel pipe guiding and straightening equipment in the prior art can complete the straightening effect through the interference cooperation of the straightening turntable. However, the straightening of this structure can only straighten the bending position, but there will still be a slight bending effect after straightening, so precise straightening control cannot be achieved, which is inconvenient to operate.

[0004] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "corrosion-resistant stainless steel pipe and its straightening machine", and its application number is "201911054784.5". This patent mainly reduces the possibility of the surface temperature of the stainless steel pipe body being too high and being worn during the friction between the stainless steel pipe body and the first pressure roller and the second pressure roller by air cooling the stainless steel pipe body; however, this straightening method can only complete simple straightening operations, which may be inconvenient for high-precision stainless steel pipes. Therefore, according to the applicant's invention, a guide straightening device capable of straightening stainless steel pipes was invented, which solves the problem that stainless steel pipes cannot be accurately straightened during use.

[0008] A second adjustment frame is fixedly connected to the other side of the middle of the straightening support plate, and buffer grooves are provided on both sides and the middle of the top of the second adjustment frame. A buffer spring is fixedly connected to the inside of the buffer groove, and a buffer plate is fixedly connected to one end of the buffer spring. Fixed frames are fixedly connected to the upper and lower sides of one end of the buffer plate, and a resisting roller is rotatably connected between the fixed frames;

[0009] A threaded plate is fixedly connected to one side of the second adjustment frame at the top of the straightening support plate, and the internal threads of the threaded plate are connected to a threaded rod. One end of the threaded rod is rotatably connected to a square frame, and the interior of the square frame is rotatably matched with a straightening roller, and the square frame and the bottom plate of the straightening support plate are in contact with each other.

[0010] Preferably, a support seat is fixedly connected to the bottom of one end of the straightening support plate, and an arc-shaped support block is fixedly connected to the top of the support seat.

[0011] Preferably, a plurality of driving motors are fixedly connected to one side of the bottom end of the straightening support plate, the driving end of the driving motor is fixedly connected to the straightening turntable, an arc-shaped fixing block is arranged at the bottom end between the arc-shaped clamping plates, and the arc-shaped fixing block is fixedly connected to the straightening support plate.

[0012] Preferably, the other end of the straightening support plate is fixedly connected to a rear side plate, a through hole is opened inside the rear side plate, second springs are fixedly connected to the upper and lower diagonals inside the through hole, and an arc-shaped clamping block is fixedly connected to the inner side of the second spring.

[0013] Preferably, two support columns are provided on one side of the straightening roller, and the support columns are fixedly connected to the straightening support plate.

[0014] Preferably, one end of the threaded rod is fixedly connected to a first hand wheel, and one end of the threaded rod is fixedly connected to a second hand wheel.

[0015] Preferably, a force sensor is sleeved inside the buffer spring, and the force sensor is fixedly connected to the inner wall of the first adjustment frame.

[0016] A guide straightening method based on a stainless steel pipe includes the following specific methods:

[0017] Step 1: First, place the bent stainless steel pipe on the top of the arc-shaped support block, then insert the straightening turntables on both sides, and then drive the drive motor to provide transmission for the rotation of the straightening turntable. At the same time, the stainless steel pipe with a larger bend can be straightened. After straightening, it enters the interior of the first adjustment frame;

[0018] Step 2: Rotate the second hand wheel to rotate the screw rod. After rotating, adjust the distance between the arc clamping plates to facilitate precise control of the diameter of the pipe. At this time, the stainless steel pipe passes through the arc clamping plate and achieves a clamping effect due to the resistance on both sides. The arc clamping plate on the top can also be lowered by extending the hydraulic cylinder at the top, so that the vertical stainless steel pipe can be pressed down and resisted.

After the support, the contact roller and the pipeline are in contact with each other, so that the straightened transportation can be maintained. When a bending position appears, the bending angle will contact the contact roller. After the contact, the buffer plate elastically presses back and contacts the touch force sensor, which can play a sensing role.

[0020] Step 4: When the resistance of the resistance roller is bent, it can be rotated again by the first hand wheel, and then the threaded rod can be matched with the threaded rod to move the threaded position of the square frame. The resistance of the straightening roller to the stainless steel pipe and the resistance of the support column can straighten the bent position again to complete precise straightening, and finally it is transported and discharged through the arc clamping plate.

Both ends of the first adjusting frame 6 are threadedly connected with screws, and one end of the screw is rotatably connected to an arc-shaped clamping plate 12. After the stainless steel pipe passes through the arc-shaped clamping plate 12, the friction on both sides achieves a clamping effect.

Buffer grooves are provided on both sides and the middle of the top of the second adjustment frame 8. A buffer spring 19 is fixedly connected to the inside of the buffer groove. When the pipeline passes through the first adjustment frame 6 and enters the inner side of the abutting roller 21, the buffer plate 20 is supported by the elastic support of the buffer spring 19. A touch force sensor 18 is sleeved inside the buffer spring 19.

When the bending position appears, the bending angle will interfere with the resistance roller 21. One side of the bottom end of the straightening support plate 1 is fixedly connected with a plurality of driving motors 2. Through the drive of the driving motor 2, it provides transportation for the rotation of the straightening turntable 5 and can also perform straightening operations on stainless steel pipes with larger bends. After straightening, it enters the interior of the first adjustment frame 6, and the driving end of the driving motor 2 is fixedly connected to the straightening turntable 5. An arc-shaped fixing block 11 is arranged at the bottom end between the arc-shaped clamping plates 12. The arc-shaped fixing block 11 increases the contact on all four sides, so as to achieve the effect of straightening again. The arc-shaped fixing block 11 is fixedly connected to the straightening support plate 1;

[0038] A threaded plate 14 is fixedly connected to one side of the second adjustment frame 8 at the top of the straightening support plate 1. The threaded plate 14 and the threaded rod 13 are threadedly matched to realize the movement of the threaded position. The internal thread of the threaded plate 14 is connected to the threaded rod 13. One end of the threaded rod 13 is fixedly connected to the first hand wheel 10. When the resistance roller 21 is bent, the first hand wheel 10 can be rotated again. After rotation, the threaded rod 13 is threadedly matched to move the threaded position of the square frame 17. One end of the screw is fixedly connected to the second hand wheel 26. The rotation of the second hand wheel 26 adjusts the rotation of the screw. After rotation, the spacing between the arc clamping plates 12 is adjusted, which is convenient for precise control of the diameter of the pipeline. One end of the threaded rod 13 is rotatably connected to the square frame 17. The inner surface of the square frame 17 is fixedly connected to the second hand wheel 26. The part is rotated and cooperated with a straightening roller 15.

The inner side of the second spring 25 is fixedly connected with an arc-shaped clamping block 23.

[0039] A guide straightening method based on a stainless steel pipe includes the following specific methods:

[0040] Step 1: First, place the bent stainless steel pipe on the arc-shaped support block 4, then insert the straightening turntable 5 on both sides, and then drive the drive motor 2 to provide transmission for the rotation of the straightening turntable 5. At the same time, the stainless steel pipe with a larger bend can be straightened, and after straightening, it enters the interior of the first adjustment frame 6;

[0041] Step 2: The second hand wheel 26 rotates to rotate the screw rod, and the spacing between the arc-shaped clamping plates 12 is adjusted after the rotation, so as to facilitate the precise control of the diameter of the pipe. At this time, the stainless steel pipe passes through the arc-shaped clamping plate 12, and the clamping effect is achieved due to the resistance on both sides. The arc-shaped clamping plate 12 on the top can also be lowered by extending the hydraulic cylinder 7 at the top, so that the vertical stainless steel pipe can be pressed down and resisted, and the arc-shaped fixing block 11 at the bottom can be used to increase the resistance on the four sides, so as to achieve the straightening effect again;

[0042] Step 3: When the pipe passes through the first adjustment frame 6 and enters the inner side of the contact roller 21, the buffer plate 20 is supported by the elastic support of the buffer spring 19. After the support, the contact roller 21 and the pipe are in contact with each other, and the straightening can be maintained. When a bending position appears, the bending angle will contact the contact roller 21. After the contact, the buffer plate 20 elastically presses back and contacts the touch force sensor 18, which can play a sensing role.

[0043] Step 4: When the resistance roller 21 is bent, the first hand wheel 10 can be rotated again to engage with the threaded rod 13, and the threaded position of the square frame 17 can be moved. The straightening roller 15 can resist the stainless steel pipe, and the support column 16 can resist to straighten the bent position again, so as to complete the precise straightening, and finally the arc-shaped clamping plate 12 can resist and transport it out.
