Description

Technical Field

[0001] This utility model is a stainless steel pipe bending device, belonging to the field of stainless steel pipe processing technology. Background Technology

[0002] Stainless steel pipe bending equipment is an important tool used to bend stainless steel sheets or pipes to achieve specific shapes and angles. For example, the utility model patent with authorization announcement number CN214719629U discloses a stainless steel pipe bending tool. The stainless steel pipe bending tool includes a base, and a rotating shaft is set in the center of the base. The rotating shaft is detachably sleeved with a disc and a handle. The handle includes a rotating plate and a rotating rod. A support plate is set at the connection between the rotating plate and the rotating rod. A pressing element is set on the side of the support plate corresponding to the disc. The distance between the slider and the edge of the disc can be adjusted by adjusting the screw. For steel pipes of different diameters, the diameter of the steel pipe is generally smaller than the arc groove range between the wheel and the side wall of the disc. Then, the screw is rotated to make the slider slide until the side wall of the wheel and the side wall of the disc clamp the steel pipe. Then, the rotating rod is held and the entire handle is moved around the rotating shaft to bend the steel pipe.

[0003] Although this stainless steel pipe bending tool is convenient for bending steel pipes, it relies solely on the rotating wheel and disc to clamp the steel pipe during the bending process. This makes it easy for the steel pipe to come out during the bending process, which could cause personal injury to the workers. Utility Model Content

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.

[0016] Please see Figure 1-5This utility model provides a technical solution for a stainless steel pipe bending device, including an upper support platform 1, on which symmetrical support and positioning side plates 2 are fixed. A hydraulic bending assembly 3 is installed between the tops of the support and positioning side plates 2. The support and positioning side plates 2 are symmetrically fixed on the upper support platform 1 for supporting the installation of the hydraulic bending assembly 3. Adjustable bending and positioning components 4 are provided at both ends of the hydraulic bending assembly 3 between the support and positioning side plates 2. Steel pipe bending protection components 5 are installed at both ends of the upper support platform 1, and a through-hole is provided between the steel pipe bending protection components 5. The stainless steel pipe body 6 of the adjustable bending positioning component 4 and the hydraulic bending component 3 has support legs 7 symmetrically installed at the bottom of the upper support platform 1. I-beams 8 are connected between the support legs 7. The adjustable bending positioning component 4, which is set between the support positioning side plates 2 and located at both ends of the hydraulic bending component 3, can provide auxiliary positioning when the hydraulic bending component 3 bends the steel pipe. The steel pipe bending protection component 5 can adjust the stainless steel pipe body 6 when bending it, thereby preventing the steel pipe from coming out during bending.

[0017] See Figure 2 The hydraulic bending assembly 3 includes an upper fixed plate 9 fixed between the tops of the supporting positioning side plates 2. A hydraulic cylinder 10 is fixedly installed at the center of the upper fixed plate 9. The movable end of the hydraulic cylinder 10 passes through the upper fixed plate 9 and is connected to an inverted U-shaped support 11. A downward bending wheel 12 is rotatably installed inside the inverted U-shaped support 11. A strip-shaped guide groove 13 is provided on the upper fixed plate 9. Guide blocks 14 extending into the strip-shaped guide groove 13 are provided on the outer walls of both sides of the inverted U-shaped support 11. The hydraulic cylinder 10 drives the inverted U-shaped support 11 to descend, thereby causing the downward bending wheel 12 to bend the stainless steel pipe body 6 from top to bottom. The strip-shaped guide groove 13, together with the guide blocks 14, guides the inverted U-shaped support 11.

[0018] See Figure 3 The adjustable bending positioning assembly 4 includes several mounting grooves 15 formed on the supporting positioning side plate 2, and abutment limiting wheels 16 are installed between the supporting positioning side plates 2. Limiting bolts extending into the mounting grooves 15 are fixed at both ends of the abutment limiting wheels 16, and a limiting nut 17 is threaded onto the end of the limiting bolt outside the mounting groove 15. Connecting posts 18 are fixedly connected to the bottom of both ends of the supporting positioning side plate 2, and a bending part 19 is integrally connected to the bottom of the supporting positioning side plate 2. The two ends of the bending part 19 are fixedly connected to the upper support platform 1 by fixing bolts 20. During adjustment, the abutment limiting wheels 16 can be adjusted to any set of mounting grooves 15 as needed. Positioning is achieved by the limiting bolts cooperating with the limiting nuts 17, thereby adjusting the distance between the two abutment limiting wheels 16 and changing the size of the bending point of the stainless steel pipe body 6 during bending.

[0019] See Figure 4-5 The steel pipe bending protection component 5 includes a support vertical plate 21 fixed on the upper support platform 1. A slot 22 is opened in the middle of the support vertical plate 21. A rotating column 23 is rotatably installed in the slot 22.

The disassembly protection kit 24 includes a lower U-shaped protection component 25 and an upper inverted U-shaped protection component 26. An inner channel 27 is formed between the lower U-shaped protection component 25 and the upper inverted U-shaped protection component 26. Fixing plates 28 are symmetrically provided on the outer walls of the lower U-shaped protection component 25 and the upper inverted U-shaped protection component 26. The fixing plates 28 are detachably connected to each other by screws 29. By passing the stainless steel pipe body 6 through the inner channel 27, when the stainless steel pipe body 6 is bent, the sleeve composed of the lower U-shaped protective part 25 and the upper inverted U-shaped protective part 26 can rotate with the tilt of both ends of the stainless steel pipe body 6, thereby playing a protective role during bending. The lower U-shaped protective part 25 and the upper inverted U-shaped protective part 26 are detachable, making it convenient to remove the bent stainless steel pipe body 6.

[0020] In use, symmetrical support and positioning side plates 2 are fixed on the upper support platform 1 for supporting the installation of the hydraulic bending assembly 3. Adjustable bending positioning components 4, located between the support and positioning side plates 2 and at both ends of the hydraulic bending assembly 3, provide auxiliary positioning when the hydraulic bending assembly 3 bends the steel pipe. The steel pipe bending protection component 5 can adjust to the stainless steel pipe body 6 when bending it, thereby preventing the steel pipe from coming off during bending. This utility model has a simple structure and is easy to use. The position of the adjustable bending positioning component 4 can be adjusted as needed to change the size of the bend of the stainless steel pipe body 6, while preventing the stainless steel pipe body 6 from coming off during bending and causing danger.
