Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe straightening technology, and specifically to a stainless steel pipe straightening device. Background Technology

[0002] In modern industrial production, stainless steel pipes are widely used in many fields, such as building structures, machinery manufacturing, petrochemicals, food and medicine, due to their excellent corrosion resistance, high strength and good processing performance. However, during the production and subsequent processing of stainless steel pipes, due to manufacturing errors of the raw materials themselves, collisions and compression during transportation, and the influence of the previous processing technology, the steel pipes often exhibit varying degrees of bending deformation. If these bent steel pipes are used directly in subsequent production stages, they will seriously affect product quality and assembly accuracy, and may even cause the entire production equipment to malfunction. Therefore, straightening stainless steel pipes is a key step to ensure their quality and performance.

[0003] Traditional stainless steel pipe straightening methods rely primarily on manual operation. Workers place the bent steel pipe on a specific workbench and gradually apply force using various tools, such as jacks and wrenches, to restore the pipe to a straight shape. This method has many drawbacks: Firstly, manual straightening is labor-intensive and inefficient, making it difficult to meet the needs of large-scale production. Secondly, the accuracy and stability of manual operation are poor; differences in the skill level and experience of different workers can lead to inconsistent straightening results, affecting product consistency and pass rate. Moreover, prolonged manual labor can easily cause worker fatigue, further increasing the risk of operational errors. This not only reduces production efficiency but may also lead to waste of raw materials and increased production costs due to quality issues.

[0004] Therefore, this utility model provides a stainless steel pipe straightening device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stainless steel pipe straightening device to solve the problem of automatically straightening stainless steel pipes without manual operation.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A stainless steel pipe straightening device includes a base, a vertical fixing plate fixedly installed at the top of the center of the base, a horizontal fixing plate fixedly installed at the top of the vertical fixing plate, a vertical sliding plate slidably connected to the inner wall of the vertical fixing plate, a vertical straightening arc plate provided on the outer wall of the vertical sliding plate, a horizontal sliding plate slidably connected to the inner wall of the horizontal fixing plate, a horizontal straightening arc plate provided on the outer wall of the horizontal sliding plate, a conveying screw rotatably connected to one end of the top of the base, the conveying screw being drivenly connected to the horizontal sliding plate, a conveying threaded plate threadedly connected to the outer wall of the conveying screw, and a retaining ring fixedly installed on the outer wall of the conveying threaded plate. This device eliminates bending of stainless steel pipes in different directions by using vertical and horizontal straightening arc plates, which allow the arc plates to press against each other, resetting and straightening the outer wall of the stainless steel pipe, preventing bending and achieving automatic straightening. This avoids the inefficiency and poor pass rate caused by manual straightening. Furthermore, after straightening, the device can automatically convey the stainless steel pipe, achieving continuous straightening function.

[0008] Preferably, a first reciprocating screw is rotatably connected to one side wall of the vertical fixed plate, one end of the first reciprocating screw is fixedly connected to the output end of the first drive motor, the first drive motor is fixedly installed on the outer wall of the vertical fixed plate, and a vertical threaded plate is fixedly installed on one side wall of the vertical slide plate, the vertical threaded plate being threadedly connected to the outer wall of the first reciprocating screw.

[0009] Preferably, a second reciprocating screw is rotatably connected to one side wall of the transverse fixed plate. One end of the second reciprocating screw is fixedly connected to the output end of the second drive motor. The second drive motor is fixedly installed on the outer wall of the transverse fixed plate. A transverse threaded plate is fixedly installed on one side wall of the transverse sliding plate. The transverse threaded plate is threadedly connected to the outer wall of the second reciprocating screw. The device has two transverse straightening arc plates and two vertical straightening arc plates, which are arranged opposite to each other. When straightening the stainless steel pipe, the device starts the first drive motor and the second drive motor, causing the two bidirectional screws to rotate, which causes the two transverse straightening arc plates and the two vertical straightening arc plates to move relative to each other, pressing and squeezing the stainless steel pipe to achieve the straightening function. The transverse threaded plate and the vertical threaded plate are located on one side of the vertical sliding plate and the transverse sliding plate, respectively. The displacement of the transverse straightening arc plates and the vertical straightening arc plates will not affect each other, which facilitates the straightening function.

[0010] Preferably, a conveying toothed plate is fixedly installed on the outer wall of the transverse threaded plate; one end of the conveying screw is rotatably connected to the outer wall of the vertical fixed plate, and a conveying gear is unidirectionally driven connected to the outer wall of one end of the conveying screw, and the conveying gear meshes with the conveying toothed plate.

[0011] Preferably, the conveying screw has an internal groove, and a sliding abutment block is slidably connected inside the groove. One end of the abutment block is triangular in shape, and a tension spring is fixedly installed at the end of the abutment block inside the groove. The other end of the tension spring is fixedly connected to the inner wall of the groove. The inner wall of the conveying gear has a slot that matches the abutment block. When the transverse straightening arc plate is displaced, the stainless steel pipe does not need to be conveyed and needs to remain stationary for straightening. At this time, when the conveying tooth plate drives the conveying gear to rotate, it will not drive the conveying screw to rotate. At this time, the inclined surface of the abutment block matches the inclined surface of the slot. Yes, the rotation of the conveying gear does not drive the conveying screw to rotate. When straightening is completed and subsequent stainless steel pipes need to be straightened, the displacement of the conveying toothed plate will drive the conveying gear to rotate. At this time, the straight surface of the anti-clamping block inside the conveying screw is opposite to the straight surface of the slot, causing the conveying gear to drive the conveying screw to rotate, thus realizing the timed conveying of stainless steel pipes. This device, through the setting of the conveying toothed plate and the conveying gear, can automatically drive the conveying screw to rotate. At the same time, when the conveying toothed plate descends, it is in the state of straightening the stainless steel pipe, and the stainless steel pipe does not need to be conveyed. After straightening is completed, it can automatically drive the stainless steel pipe to be conveyed, realizing the linkage effect between straightening and conveying, and continuous straightening.

[0012] Preferably, an adjusting plate is fixedly installed on the outer wall of the vertical straightening arc plate. The adjusting plate is slidably connected inside the vertical fixed plate, and a top groove is formed on the inner wall of the adjusting plate. An adjusting shaft is slidably connected to the inner wall of the vertical fixed plate, and a top inclined plate is fixedly installed on the outer wall of the adjusting shaft. The top inclined plate matches the top groove. In order to be suitable for the use of stainless steel pipes of various diameters, this device adjusts the position of the adjusting shaft so that the top inclined plate abuts against the top groove. At this time, the position of the adjusting plate is changed, thereby realizing the adjustment of the position of the vertical straightening arc plate. The adjustment method of the vertical straightening arc plate in this device is the same as that of the horizontal straightening arc plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. In order to eliminate the bending phenomenon of stainless steel pipes in different directions, this device uses vertical and horizontal straightening arc plates to make the arc plates press against each other, thereby resetting and straightening the outer wall of the stainless steel pipe, preventing bending, and realizing automatic straightening. This avoids the low efficiency and poor pass rate caused by manual straightening. At the same time, after straightening, this device can automatically transport the stainless steel pipe, realizing continuous straightening function.

[0015] 2. The transverse threaded plate and the vertical threaded plate of this device are located on one side of the vertical slide plate and the transverse slide plate, respectively. The transverse straightening arc plate and the vertical straightening arc plate are displaced without affecting each other, which facilitates the straightening function.

[0016] 3. This device, through the setting of the conveying toothed plate and the conveying gear, can automatically drive the conveying screw to rotate. At the same time, when the conveying toothed plate descends, it is in the state of straightening the stainless steel pipe. The stainless steel pipe does not need to be conveyed. After the straightening is completed, it can automatically drive the stainless steel pipe to be conveyed, realizing the linkage effect of straightening and conveying, and continuous straightening.

[0017] 4. In order to be applicable to stainless steel pipes of various diameters, this device adjusts the position of the sliding adjustment shaft so that the abutting inclined plate and the abutting groove abut against each other. At this time, the position of the adjustment plate is changed, thereby adjusting the position of the vertical straightening arc plate. The adjustment method of the vertical straightening arc plate and the horizontal straightening arc plate of this device is the same. Attached Figure Description

Figure 1-2 As shown, the system includes a base 1, a vertical fixing plate 2 fixedly installed at the top of the middle part of the base 1, a horizontal fixing plate 3 fixedly installed at the top of the vertical fixing plate 2, a vertical sliding plate 4 slidably connected to the inner wall of the vertical fixing plate 2, a vertical straightening arc plate 5 provided on the outer wall of the vertical sliding plate 4, a horizontal sliding plate 6 slidably connected to the inner wall of the horizontal fixing plate 3, a horizontal straightening arc plate 7 provided on the outer wall of the horizontal sliding plate 6, a conveying screw 8 rotatably connected to one end of the top of the base 1, the conveying screw 8 being drivenly connected to the horizontal sliding plate 6, and the outer wall of the conveying screw 8 being... A conveying threaded plate 9 is threaded onto the wall, and a retaining ring 10 is fixedly installed on the outer wall of the conveying threaded plate 9. In order to eliminate the bending phenomenon of stainless steel pipe in different directions, this device uses the setting of vertical straightening arc plate 5 and horizontal straightening arc plate 7 to make the arc plates squeeze each other, so as to restore and straighten the outer wall of the stainless steel pipe, prevent bending, realize automatic straightening, and avoid the low efficiency and poor pass rate caused by manual straightening. At the same time, after straightening, this device can automatically convey the stainless steel pipe to realize continuous straightening function.

[0027] Preferred options are listed below. Figure 1 As shown, a first reciprocating screw 12 is rotatably connected to one side wall of the vertical fixed plate 2. One end of the first reciprocating screw 12 is fixedly connected to the output end of the first drive motor. The first drive motor is fixedly installed on the outer wall of the vertical fixed plate 2. A vertical threaded plate 11 is fixedly installed on one side wall of the vertical slide plate 4. The vertical threaded plate 11 is threadedly connected to the outer wall of the first reciprocating screw 12.

[0028] Preferred options are listed below. Figure 1-2 As shown, a second reciprocating screw 14 is rotatably connected to one side wall of the transverse fixed plate 3. One end of the second reciprocating screw 14 is fixedly connected to the output end of the second drive motor. The second drive motor is fixedly installed on the outer wall of the transverse fixed plate 3. A transverse threaded plate 13 is fixedly installed on one side wall of the transverse sliding plate 6. The transverse threaded plate 13 is threadedly connected to the outer wall of the second reciprocating screw 14. The device has two transverse straightening arc plates 7 and two vertical straightening arc plates 5, which are arranged opposite to each other. When straightening the stainless steel pipe, the device starts the first drive motor and the second drive motor, causing the two bidirectional screws to rotate, which causes the two transverse straightening arc plates 7 and the two vertical straightening arc plates 5 to be displaced relative to each other, pressing and squeezing the stainless steel pipe to achieve the straightening function. The transverse threaded plate 13 and the vertical threaded plate 11 are located on one side of the vertical sliding plate 4 and the transverse sliding plate 6, respectively. The displacement of the transverse straightening arc plates 7 and the vertical straightening arc plates 5 will not affect each other, which facilitates the straightening function.

[0029] Preferred options are listed below. Figure 2-3As shown, a conveying toothed plate 15 is fixedly installed on the outer wall of the transverse threaded plate 13; one end of the conveying screw 8 is rotatably connected to the outer wall of the vertical fixed plate 2, and a conveying gear 16 is unidirectionally driven connected to the outer wall of one end of the conveying screw 8, and the conveying gear 16 meshes with the conveying toothed plate 15.

[0030] Preferred options are listed below. Figure 4 As shown, the conveying screw 8 has a groove 17 inside, and a slidable abutment block 18 is slidably connected inside the groove 17. One end of the abutment block 18 is triangular in shape, and a tension spring 19 is fixedly installed at one end of the abutment block 18 inside the groove 17. The other end of the tension spring 19 is fixedly connected to the inner wall of the groove 17. The inner wall of the conveying gear 16 has a slot 20, which matches the abutment block 18. When the transverse straightening arc plate 7 is displaced, the stainless steel pipe does not need to be conveyed and needs to remain stationary for straightening. At this time, when the conveying tooth plate 15 drives the conveying gear 16 to rotate, it will not drive the conveying screw 8 to rotate. At this time, the inclined surface of the abutment block 18 is opposite to the inclined surface of the slot 20. The rotation of the conveying gear 16 will not drive the conveying screw 8 to rotate. When straightening is completed and subsequent stainless steel pipes need to be straightened, the displacement of the conveying toothed plate 15 will drive the conveying gear 16 to rotate. At this time, the straight surface of the abutting inclined block 18 inside the conveying screw 8 is opposite to the straight surface of the slot 20, so that the conveying gear 16 drives the conveying screw 8 to rotate, realizing the timed conveying of stainless steel pipes. Through the setting of the conveying toothed plate 15 and the conveying gear 16, this device can automatically drive the conveying screw 8 to rotate. At the same time, when the conveying toothed plate 15 descends, it is in the state of straightening the stainless steel pipe. The stainless steel pipe does not need to be conveyed. After straightening is completed, it can automatically drive the stainless steel pipe to be conveyed, realizing the linkage effect of straightening and conveying, and continuous straightening.

[0031] Preferred options are listed below. Figure 5 As shown, an adjusting plate 21 is fixedly installed on the outer wall of the vertical straightening arc plate 5. The adjusting plate 21 is slidably connected to the inside of the vertical fixed plate 2. A top groove 22 is provided on the inner wall of the adjusting plate 21. An adjusting shaft 23 is slidably connected to the inner wall of the vertical fixed plate 2. A top inclined plate 24 is fixedly installed on the outer wall of the adjusting shaft 23. The top inclined plate 24 matches the top groove 22. In order to be suitable for the use of stainless steel pipes of various diameters, the position of the adjusting shaft 23 is slidably adjusted so that the top inclined plate 24 abuts against the top groove 22. At this time, the position of the adjusting plate 21 is changed, thereby realizing the adjustment of the position of the vertical straightening arc plate 5. The adjustment method of the vertical straightening arc plate 5 and the horizontal straightening arc plate 7 of this device is the same.

[0032] To eliminate bending of stainless steel pipes in different directions, this device uses vertical straightening arc plates 5 and horizontal straightening arc plates 7. These plates press against each other, repositioning and straightening the outer wall of the stainless steel pipe, preventing bending and achieving automatic straightening. This avoids the inefficiency and poor yield rate associated with manual straightening. Furthermore, after straightening, the device automatically transports the stainless steel pipe, enabling continuous straightening. The horizontal threaded plate 13 and vertical threaded plate 11 are located on one side of the vertical slide plate 4 and horizontal slide plate 6, respectively. Their displacement by the horizontal straightening arc plates 7 and 5 does not interfere with each other, facilitating the straightening function. The device utilizes conveying teeth... The arrangement of plate 15 and conveying gear 16 enables automatic rotation of the conveying screw 8. Simultaneously, when the conveying gear plate 15 descends, it is in a straightening state for the stainless steel pipe, which does not require conveying. After straightening, it automatically drives the stainless steel pipe for conveying, achieving a linkage effect between straightening and conveying for continuous straightening. To accommodate stainless steel pipes of various diameters, the device adjusts the position of the sliding adjustment shaft 23, causing the abutting inclined plate 24 to abut against the abutting groove 22. This changes the position of the adjusting plate 21, thereby adjusting the position of the vertical straightening arc plate 5. The adjustment method of the vertical straightening arc plate 5 is the same as that of the horizontal straightening arc plate 7.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
