Description

Technical Field

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

[0002] Stainless steel pipes are widely used in daily life and production. In order to meet the requirements of the environment, stainless steel pipes need to be bent into a certain angle, which requires the use of a stainless steel pipe bending device.

[0003] Existing pipe bending devices cannot effectively rotate stainless steel pipes after fixing them. This means that when bending the stainless steel pipe in different directions is required, workers must manually rotate and then re-fix it. This is not only time-consuming and labor-intensive but also increases the workload of workers and reduces the bending efficiency. Furthermore, existing pipe bending devices cannot effectively adjust the height of the bending components. This also means that when bending the stainless steel pipe in different positions is required, workers must manually move and then re-fix it, further reducing bending efficiency and the overall practicality of the device.

[0004] Comparing this application with Chinese patent publication number CN219944231U, this application discloses a thin-walled stainless steel pipe bending device, relating to the technical field of steel pipe bending devices. It includes a support base with a rectangular opening on one outer wall. The inner walls of both sides of the rectangular opening are fixedly connected to the same fixed seat. Two sliding rods are fixedly connected to the fixed seat and one inner wall of the rectangular opening. A driving seat is slidably connected to the outer walls of the two sliding rods. A groove is formed on one outer wall of the driving seat, and a sliding seat is slidably connected to the inner wall of the groove. Two springs are fixedly connected to one inner wall of the groove, with one end of each spring fixedly connected to the sliding seat. A positioning seat is fixedly connected to one outer wall of the sliding seat. This application, by setting a positioning seat and an arc-shaped seat on the support base, facilitates the auxiliary positioning of the stainless steel pipe body through the cooperation between the positioning seat and the arc-shaped seat. The arc-shaped seat and the driving seat increase the contact area with the outer wall of the steel pipe, thereby effectively preventing local deformation of the steel pipe during bending.

[0005] The above solution can effectively prevent the steel pipe from deforming during bending. However, after fixing the stainless steel pipe, the above solution still cannot effectively rotate the stainless steel pipe. Furthermore, the above solution still cannot effectively adjust the height and position of the bending component according to actual needs, and thus fails to solve the problems mentioned in the background art.

[0006] Therefore, those skilled in the art have provided a stainless steel pipe bending device to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 5 As shown, this embodiment provides a stainless steel pipe bending device, including a support platform 1, and further comprising:

[0030] The fixed frame 14 is rotatably connected to the bottom of the support platform 1. The fixed frame 14 is provided with a tube body 2 above it. The upper surface of the support platform 1 is provided with a guide groove for the tube body 2 to move through.

[0031] A fixing component is provided at the bottom of the fixing frame 14 and is used to fix the tube body 2.

[0032] The rotating components are symmetrically arranged outside the fixed frame 14 and are used to rotate the tube body 2.

[0033] L-shaped plates 5 are symmetrically arranged above the support platform 1, and a fixed roller 6 is fixedly connected between the two L-shaped plates 5.

[0034] The bending assembly is respectively set on the outside of the two L-shaped plates 5 and is used to bend the tube body 2;

[0035] The adjustment components are symmetrically arranged on the upper surface of the support platform 1 and are used to adjust the height of the fixed roller 6 and the bending component, so that the bending component can bend the tube 2 at different positions.

[0036] The working principle described above is as follows: When bending tube 2 is required, it is only necessary to first fix and clamp tube 2 using the fixing component. After tube 2 is fixed, the bending component and the fixing roller 6 work together to bend tube 2 conveniently and effectively. When bending tube 2 in different directions is required, it is only necessary to rotate the component to easily rotate tube 2, thereby enabling the bending component to effectively bend tube 2 in different directions without the need for manual rotation and re-fixing by the operator. This effectively improves the bending efficiency of tube 2 and reduces the workload of the operator. When bending tube 2 at different positions is required, the height of the fixing roller 6 and the bending component can be easily adjusted by adjusting the component. This allows the bending component to work with the fixing roller 6 to bend tube 2 at different positions, effectively improving the overall practicality of the device and saving time and effort.

[0037] To facilitate convenient and effective fixing of the pipe body 2, the fixing assembly includes a fixing plate 8 fixedly connected to the bottom of the fixing frame 14. A bidirectional threaded rod 10 is rotatably connected to the inner wall of the fixing plate 8. The other end of the bidirectional threaded rod 10 extends to the outside of the fixing plate 8 and is fixedly connected to a knob 9. Threaded plates 11 are symmetrically arranged on the outside of the bidirectional threaded rod 10. A guide groove for the threaded plates 11 to move is formed on the upper surface of the fixing plate 8. Arc-shaped clamping plates 13 are fixedly connected to opposite sides of the two threaded plates 11 via connecting rods 12. Anti-slip pads are adhered to opposite sides of the two arc-shaped clamping plates 13. When fixing of the pipe body 2 is required, only… First, the tube 2 needs to be placed on the upper surface of the fixing frame 14 through the guide groove on the upper surface of the support platform 1. Then, turn the knob 9. The knob 9 will drive the bidirectional threaded rod 10 to rotate synchronously. The threaded plate 11 will move synchronously outside the bidirectional threaded rod 10, driving the connecting rod 12 and the arc-shaped clamp 13 to move synchronously. When the opposite sides of the two arc-shaped clamps 13 are in contact with the outside of the tube 2, the tube 2 can be effectively fixed and clamped by the arc-shaped clamps 13. The anti-slip pad can effectively increase the friction between the arc-shaped clamps 13 and the tube 2, thereby effectively improving the fixing effect of the tube 2.

[0038] Considering that the tube body 2 needs to be rotated when bending it in different directions, the rotating assembly includes connecting plates 15 symmetrically arranged outside the fixed frame 14. A fixed sleeve 16 is fixedly connected to the bottom of each connecting plate 15. A fixed rod 23 is provided inside the fixed sleeve 16. A pull ring is fixedly connected to one end of the fixed rod 23. A contact plate 24 is fixedly connected to the outside of the fixed rod 23. A return spring 25 is sleeved on the outside of the fixed rod 23, and the return spring 25 abuts against the contact plate 24 and the fixed sleeve 16. Guide grooves for the movement of the fixed rod 23 are provided on the contact surfaces of the fixed sleeve 16 and the connecting plate 15. Guide grooves for the movement of the fixed rod 23 are also provided at equal intervals on the upper surface of the support platform 1. When the tube body 2 needs to be rotated, simply pull the pull ring first. The pull ring drives the fixed rod 23 to move synchronously, and the fixed rod 23 then drives the contact plate 24 to move synchronously. During the movement of the contact plate 24, it will squeeze the return spring 25. When the fixed rod 23 is disengaged from the guide groove on the upper surface of the support platform 1, the connecting plate 15 is rotated. At this time, the connecting plate 15 drives the fixed frame 14 to rotate synchronously, and the fixed frame 14 drives the tube body 2 to rotate synchronously. When the tube body 2 rotates to the appropriate position, the pull ring is released. At this time, the return spring 25 is reset, and the contact plate 24 and the fixed rod 23 move synchronously. When the fixed rod 23 is inserted into the guide groove on the upper surface of the support platform 1, the rotation position of the tube body 2 can be fixed. At this time, the tube body 2 can be bent in different directions, which effectively improves the overall practicality of the device.

[0039] To effectively bend the tube 2, the bending assembly includes rotating rods 17 rotatably connected to the outside of two L-shaped plates 5. Mounting plates 18 are fixedly connected to the other ends of both rotating rods 17. A bending rod 19 is rotatably connected between the two mounting plates 18. A bending roller 20 is fixedly connected to the outside of the bending rod 19. Push handles 21 are fixedly connected to the outside of both mounting plates 18. When bending of the tube 2 is required, simply push the push handle 21. The push handle 21 will then drive the mounting plates 18 to move synchronously, which in turn drives the rotating rods 17 to rotate synchronously. During the movement of the mounting plates 18, the bending rod 19 and the bending roller 20 will also move synchronously. Thus, the tube 2 can be effectively bent through the cooperation between the bending roller 20 and the fixed roller 6.

[0040] To effectively adjust the height of the fixed roller 6 and the bending assembly, the adjustment assembly includes mounting plates 3 symmetrically arranged on the upper surface of the support platform 1. The mounting plates 3 have a movable plate 4 inside, and the upper surface of the movable plate 4 is fixedly connected to the bottom of the L-shaped plate 5. A fixing block 7 is fixedly connected to the outside of the mounting plates 3. A sliding rod 26 is fixedly connected inside the fixing block 7. An abutment plate 27 is provided inside the fixing block 7, and a guide groove for the sliding rod 26 to move is opened inside the abutment plate 27. An abutment spring 28 is sleeved on the outside of the sliding rod 26, and the abutment spring 28 abuts against the abutment plate 27 and the fixing block 7. Side plates 29 are symmetrically arranged outside the abutment plates 27, and a pull plate is fixedly connected to the outside of each pair of side plates 29. Insert rods 30 are symmetrically arranged on opposite sides of the two abutment plates 27. Guide grooves for the insert rods 30 to move are opened on the contact surfaces of the fixing block 7 and the mounting plates 3. Guide grooves for the insert rods 30 to move are opened at equal intervals inside the movable plate 4. When it is necessary to adjust the height of the fixed roller 6 and the bending assembly... During adjustment, simply pull the pull plate first. The pull plate will then move the side plate 29 synchronously. The side plate 29 will then move the abutment plate 27 synchronously outside the slide rod 26. During the movement of the abutment plate 27, it will compress the abutment spring 28. The abutment plate 27 will also move the insertion rod 30 synchronously. When the insertion rod 30 disengages from the guide groove inside the movable plate 4, the movable plate 4 will be pulled out from inside the mounting sleeve 3. When the movable plate 4 moves the L-shaped plate 5 to the appropriate height position, the pull plate will be released. At this time, the abutment spring 28 will reset and move the abutment plate 27 synchronously. The abutment plate 27 will then move the insertion rod 30 synchronously. When the insertion rod 30 is inserted into the guide groove inside the movable plate 4, the mounting sleeve 3 and the movable plate 4 can be fixed. At this time, the height position of the fixed roller 6 and the bending assembly can be adjusted, so that the fixed roller 6 and the bending assembly can effectively bend different positions of the tube 2, further improving the overall practicality of the device.

[0041] In addition, to prevent the staff from slipping when pushing the handle 21, both handles 21 are fitted with anti-slip sleeves 22. The two anti-slip sleeves 22 have herringbone anti-slip grooves at equal intervals on their outer surfaces. The anti-slip sleeves 22 effectively increase the friction between the staff's hands and the handle 21, thereby preventing the staff from slipping when pushing the handle 21 and affecting the bending effect of the tube body 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
