Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a pipe bending device for hydrogen energy pipe processing. Background Art

[0002] As society progresses, energy consumption is gradually increasing. Due to the non-renewable problem of traditional energy, the research on new energy has become a hot topic in today's society. Among them, hydrogen energy has the advantages of being pollution-free and renewable, and has gradually become one of the key research directions. At present, there are many industries of hydrogen energy, such as new energy vehicles, electricity and other industries. The use of hydrogen energy can be seen. When hydrogen energy is used, hydrogen energy pipes are needed to transmit energy. Due to the changeable transmission direction, hydrogen energy pipes need to be bent during the production and processing process. Therefore, pipe bending devices, as equipment that can drive hydrogen energy pipes to bend, are widely used in hydrogen energy pipe processing.

[0003] The patent with publication number CN218191862U discloses a pipe bending device for processing hydrogen-conducting pipes, which includes a base plate and a U-shaped plate, a fixed shaft is installed on the base plate, a fixed wheel is connected to the fixed shaft, the U-shaped plate has two first parallel parts and a second parallel part arranged oppositely, a movable wheel is rotatably installed inside the first parallel part and the second parallel part, the movable wheel is arranged oppositely to the fixed wheel, a processing area is formed between the movable wheel and the fixed wheel, and a handle is fixedly connected to the U-shaped plate. When bending the pipe, the handle can be driven to rotate after the pipe is inserted into the processing area, and the rotation of the handle drives the U-shaped plate and the movable wheel to rotate, and then the movable wheel drives the key bending deformation to achieve the purpose of bending. Although the device can realize the bending of the hydrogen-conducting pipe, the above device uses manual labor. The bending is performed in a professional manner, and the bending angle needs to be determined by the operator with the naked eye, resulting in that the bending angle cannot be accurately controlled. In order to solve this problem, the prior art CN102974665A discloses a pipe bending forming device, which includes a base and two limiting driven wheels and a driving wheel. The limiting driven wheels are rotatably and symmetrically arranged on the base, and the upper part of the driving wheel is connected to the hydraulic rod so that its height can be adjusted and arranged on the center line between the two limiting driven wheels. During operation, the driving wheel bends the raw material straight pipe to form a bent pipe under the downward pressure of the hydraulic rod to achieve the bending purpose. The above-mentioned pipe bending forming device avoids the defect of observing the bending angle with the naked eye when bending the pipe, and instead uses the distance between the two limiting driven wheels to determine the bending angle of the bent pipe. However, the above device still has the following defects during use: since the two limit driven wheels are assembled on the base, the bending angle of the bent pipe is adjusted by the distance between the two limit driven wheels, but the distance between the two limit driven wheels cannot be adjusted, resulting in a fixed bending angle, and the bending angle cannot be bent to a required angle as needed, causing certain inconveniences to people's use. For this reason, we propose a pipe bending device for hydrogen energy pipe processing, which is used to bend the hydrogen energy pipe to a required angle. Summary of the Utility Model

Detailed implementation manners

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0030] Refer to Figures 1 - 4 , which is a schematic structural diagram of the pipe bending device in this embodiment. The pipe bending device in this embodiment is used to bend the hydrogen energy pipe. Since the hydrogen energy pipe is made of metal pipe fittings for transporting hydrogen energy and the transportation direction can be adjusted as needed, a pipe bending device is required to process and bend the hydrogen energy pipe.

[0031] As Figure 2 shown, the pipe bending device in this embodiment includes a base 100. Symmetrically fixed to the base 100 are support frames 103, and the top of the support frames 103 is connected to a top frame 104. The support frames 103 and the top frame 104 form a U-shaped frame structure fixed on the base 100. Fixed to the lower surface of the top frame 104 is a fixed wheel 105. Fixed to the opposite side walls of the support frames 103 are slide rails 103a, and a pipe bending driving member 200 is slidably assembled between the support frames 103. A pipe bending processing area is formed between the pipe bending driving member 200 and the fixed wheel 105. The straight hydrogen energy pipe passes through the pipe bending processing area, and the pipe bending driving member 200 and the fixed wheel 105 cooperate to bend the hydrogen energy pipe.

[0032] In this embodiment, traveling wheels 201a are assembled on the side wall of the pipe bending driving member 200. The pipe bending driving member 200 is slidably assembled on the slide rails 103a on the side walls of the support frames 103 through the traveling wheels 201a. The pipe bending driving member 200 can slide along the height direction of the support frames 103 and cooperate with the limiting of the fixed wheel 105 to bend the hydrogen energy pipe.

[0033] As Figures 5 - 7As shown, in this embodiment, the elbow active member 200 includes a sliding frame 201. The sliding frame 201 is a U-shaped frame structure with openings on both sides. The sliding frame 201 is slidably assembled on the slide rail 103a through the traveling wheels 201a. And a fixed rod 202 is fixedly connected inside the sliding frame 201. A first connecting arm 203 and a second connecting arm 204 are symmetrically assembled on the fixed rod 202. A V-shaped structure with a certain angle is formed between the first connecting arm 203 and the second connecting arm 204. Mounting shafts are connected between the first connecting arms 203 and between the second connecting arms 204. Driving wheels 205 are assembled on the mounting shafts. In this embodiment, the driving wheels 205 are located below the fixed wheels 105. And grooves are provided on the surfaces of both the driving wheels 205 and the fixed wheels 105 for limiting the hydrogen energy pipe. In this embodiment, when the elbow active member 200 moves upward along the support frame 103, the hydrogen energy pipe is located in the groove of the driving wheel 205 and moves synchronously with the driving wheel 205 until the hydrogen energy pipe abuts against the groove of the fixed wheel 105, thereby achieving the purpose of limiting the hydrogen energy pipe. The elbow active member 200 continues to rise. Due to the certain angle formed between the first connecting arm 203 and the second connecting arm 204, it cooperates with the fixed wheel 105 to bend the hydrogen energy pipe, and the bending angle is the same as the angle between the first connecting arm 203 and the second connecting arm 204.

[0034] In this embodiment, in order to enable the bending angle of the hydrogen energy pipe to be adjustable, in this embodiment, both the first connecting arm 203 and the second connecting arm 204 are rotatably assembled on the fixed rod 202. And both the first connecting arm 203 and the second connecting arm 204 can rotate relative to the fixed rod 202 to adjust the angle between the first connecting arm 203 and the second connecting arm 204. In order to limit the first connecting arm 203 and the second connecting arm 204 after the angle between the first connecting arm 203 and the second connecting arm 204 is adjusted, a regulator 206 is further provided inside the sliding frame 201 in this embodiment. The regulator 206 is used on the one hand to drive the first connecting arm 203 and the second connecting arm 204 to rotate, and on the other hand to limit the first connecting arm 203 and the second connecting arm 204 after rotation, so as to ensure the stability of the first connecting arm 203 and the second connecting arm 204.

[0035] As Figure 5 and Figure 8 、 Figure 9As shown in the figure, regulators 206 are provided on both sides of the sliding frame 201 in this embodiment. The regulator 206 includes a connecting rod 206a fixedly connected inside the sliding frame 201. A sleeve 206b is sleeved on the connecting rod 206a. A connecting sleeve 206e is sleeved on the rotating shafts of the first connecting arm 203 and the second connecting arm 204. A driver 206d is connected between the connecting sleeve 206e and the sleeve 206b. In this embodiment, when it is necessary to adjust the rotation of the first connecting arm 203 and the second connecting arm 204, the driver 206d works to drive the first connecting arm 203 and the second connecting arm 204 to rotate relative to the fixed rod 202, thereby adjusting the angle between the first connecting arm 203 and the second connecting arm 204. After the adjustment is completed, the driver 206d stops working to limit the first connecting arm 203 and the second connecting arm 204, ensuring the stability of the first connecting arm 203 and the second connecting arm 204. In addition, in order to prevent the driver 206d from swinging during operation, in this embodiment, a telescopic spring 206c is also sleeved on the connecting rod 206a. The telescopic spring 206c is sleeved on the connecting rod 206a and its two ends are pressed against the ends of the sleeve 206b, so that the sleeve 206b can only rotate coaxially on the connecting rod 206a when the driver 206d works, avoiding problems such as shaking and swinging, thereby ensuring the stability of the driver 206d during operation. In this embodiment, the operator can adjust the angle between the first connecting arm 203 and the second connecting arm 204 by the operation of the driver 206d according to the required bending angle of the hydrogen energy pipe. After the angle adjustment is completed, the pipe bending actuator 200 moves upward along the support frame 103 and cooperates with the fixed wheel 105 to bend the hydrogen energy pipe, so that the bending angle is the angle between the first connecting arm 203 and the second connecting arm 204, facilitating the bending of the hydrogen energy pipe as required. Embodiment 2

[0036] Refer to Figures 1 - 2, The difference between this embodiment and Embodiment 1 is that this embodiment provides a driving assembly for driving the movement of the elbow active part 200. The driving assembly in this embodiment includes a distance wire gauge 101 fixed on the base 100. A slider 101a is installed on the distance wire gauge 101, and a driving cylinder 102 is movably connected to the slider 101a. The distance wire gauge 101 works to drive the slider 101a to drive the driving cylinder 102 to move, so as to adjust the distance between the driving cylinder 102 and the support frame 103. In this embodiment, the power end of the driving cylinder 102 is hinged with a connecting piece 102a, and rotating arms are symmetrically and movably assembled on the connecting piece 102a. One of the rotating arms is hinged with a fixing piece 102b at its end, and the fixing piece 102b is fixed on the base 100. The other rotating arm is hinged at the end on the elbow active part 200. In this embodiment, when the driving cylinder 102 works, it drives the connecting piece 102a to move. When the connecting piece 102a moves, it is used to drive the angle between the rotating arms to change. Since one of the rotating arms is connected to the fixing piece 102b, and the fixing piece 102b is fixed on the base 100, therefore, the cooperation between the rotating arm and the fixing piece 102b makes the angle of the driving cylinder 102 change, and at the same time, the other rotating arm pushes the elbow active part 200 upward to bend the hydrogen energy pipe. In this embodiment, the connecting piece 102a and the rotating arm are used in cooperation to drive the movement of the elbow active part 200. Of course, other driving assemblies directly acting on the elbow active part 200 and driving the elbow active part 200 to move up and down can also be applied in this embodiment.

[0037] Working principle: In the present invention, the first connecting arm 203 and the second connecting arm 204 are driven by the driver 206d to rotate to form the required angle. After the angle adjustment is completed, the driver 206d limits the first connecting arm 203 and the second connecting arm 204. Then, after the hydrogen energy pipe passes through the working area between the fixed wheel 105 and the driving wheel 205, the driving cylinder 102 works, and through the cooperation of the connecting piece 102a and the rotating arm, it drives the elbow active part 200 to move upward and cooperate with the fixed wheel 105 to bend the hydrogen energy pipe into the required angle.

[0038] The control mode of the present invention is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The power supply is also common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.
