Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, specifically an automatic pipe bending machine. Background Technology

[0002] Pipe bending machines are machines used for bending pipes and can also be used as jacks. They are generally divided into CNC pipe bending machines and hydraulic pipe bending machines, and are used in pipeline laying and repair in power construction, railway and highway construction, bridges, ships and other fields.

[0003] With the development of science and technology and the improvement of people's living standards, people have higher requirements for the precision of machinery. The current fully automatic pipe bending machine is relatively slow in pipeline transportation, so it cannot control the movement of the pipe body quickly and accurately when in use, which affects the work efficiency. Therefore, a fully automatic pipe bending machine was proposed to solve this problem. With the development of the times, pipe bending machines have gradually appeared in people's field of vision. Conventional pipe bending machines achieve the purpose of bending by pushing the steel pipe in two directions at the same time, and can only perform single-point bending. Utility Model Content

There are multiple guide wheels A, which are respectively fitted onto the outside of different fixed shafts A and rotatably connected to them. There is a gap between every two guide wheels A. The steel pipe passes through the gap between two guide wheels A and abuts against the two guide wheels A.

[0010] Preferably, the fixed shaft A has two symmetrical limiting rings, which are respectively attached to the upper and lower sides of the worktable. The two limiting rings can limit the fixed shaft A and prevent it from falling off the worktable.

[0011] Preferably, the fixed shaft A is slidably connected to the worktable inside the guide rail. The fixed shaft A can slide inside the guide rail, thereby adjusting the position of the guide wheel A and changing the distance between the two guide wheels A. This not only allows for clamping the outside of steel pipes of different diameters, but also controls the bending angle of the steel pipe.

[0012] Preferably, each fixed shaft A is connected to a hydraulic push rod A at its bottom. The telescopic end of the hydraulic push rod A is connected and fixed to the fixed shaft A. The top of the hydraulic push rod A is installed on the bottom of the worktable by screws. The hydraulic push rod A can drive the guide wheel A to move. The two guide wheels A clamp the two sides of the steel pipe at the same time and output continuously, thereby bending the steel pipe.

[0013] Preferably, the sides of guide wheel A, guide wheel B, and the shaping bracket are all arc-shaped, and the arc-shaped structural design can better fit the contour of the steel pipe.

[0014] Preferably, the steel pipe has two symmetrical drive wheels on both sides, each drive wheel has multiple anti-slip grooves, the two drive wheels abut against the two sides of the steel pipe, and each drive wheel has a drive gear at its bottom. The two drive gears mesh with each other, and a drive motor is connected to the bottom of one of the drive gears.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the steel pipe passes the guide wheel B, the hydraulic push rod B is activated to push the steel pipe through the shaping bracket. The steel pipe is pushed and subjected to force by the guide wheel B and the shaping bracket, thereby achieving the purpose of bending. The steel pipe is continuously pushed, and the two guide wheels A clamp the two sides of the steel pipe at the same time, and continue to output, thereby bending the steel pipe. The fixed shaft A can slide inside the guide rail, thereby adjusting the position of the guide wheels A and changing the distance between the two guide wheels A. It can not only clamp the outside of steel pipes of different diameters, but also control the bending angle of the steel pipe. By inserting the steel pipe into two different guide wheels A, different angles can be bent, and multiple simultaneous bends can be performed. Attached Figure Description

[0023] Please see Figure 1-2 This utility model provides a technical solution: an automatic pipe bending machine, comprising;

[0024] The workbench 100 and the steel pipe 700 are provided. The workbench 100 has a bent pipe structure, which includes a guide wheel A200, a guide wheel B400, and a hydraulic push rod B500.

[0025] The steel pipe 700 is located on the top of the workbench 100. The workbench 100 is provided with multiple guide rails 101. Each guide rail 101 has a fixed shaft A201 embedded inside. There are multiple guide wheels A200. The multiple guide wheels A200 are respectively sleeved on the outside of different fixed shafts A201 and rotatably connected to them. There is a gap between every two guide wheels A200. The steel pipe 700 passes through the gap between two guide wheels A200 and abuts against the two guide wheels A200.

[0026] The guide wheel B400 is located on one side of the steel pipe 700. The guide wheel B400 abuts against the steel pipe 700, and the middle part of the guide wheel B400 has a fixed shaft B401. The fixed shaft B401 is rotatably connected to the guide wheel B400, and the bottom of the fixed shaft B401 is fixedly connected to the top of the worktable 100.

[0027] One end of the hydraulic push rod B500 has a shaping bracket 501. The hydraulic push rod B500 is located on the top of the worktable 100, and the shaping bracket 501 abuts against the steel pipe 700 on the side away from the guide wheel B400.

[0028] Furthermore, the fixed shaft A201 has two symmetrical limiting rings 202, which are respectively attached to the upper and lower sides of the worktable 100. The two limiting rings 202 can limit the fixed shaft A201 and prevent the fixed shaft A201 from falling off the worktable 100.

[0029] Furthermore, the fixed shaft A201 is slidably connected to the worktable 100 inside the guide rail 101. The fixed shaft A201 can slide inside the guide rail 101, thereby adjusting the position of the guide wheel A200 and changing the distance between the two guide wheels A200. This not only allows for clamping the outside of steel pipes of different diameters, but also controls the bending angle of the steel pipe 700.

[0030] Furthermore, a hydraulic push rod A300 is connected to the bottom of each fixed shaft A201. The telescopic end of the hydraulic push rod A300 is connected and fixed to the fixed shaft A201. The top of the hydraulic push rod A300 is installed on the bottom of the workbench 100 by screws. The hydraulic push rod A300 can drive the guide wheel A200 to move. The two guide wheels A200 simultaneously clamp the two sides of the steel pipe 700 and continuously output, thereby bending the steel pipe 700.

[0031] Furthermore, the sides of guide wheel A200, guide wheel B400, and shaping bracket 501 are all arc-shaped, and the arc-shaped structural design can better fit the contour of the steel pipe.

[0032] Furthermore, the steel pipe 700 has two symmetrical drive wheels 600 on both sides. The drive wheels 600 have multiple anti-slip grooves. The two drive wheels 600 abut against the two sides of the steel pipe 700. Each drive wheel 600 has a drive gear 601 at its bottom. The two drive gears 601 mesh with each other, and the bottom of one of the drive gears 601 is connected to a drive motor 602.

[0033] Working principle: In use, one end of the steel pipe 700 is passed through the two drive wheels 600. The drive motor 602 is started to drive the drive gear 601 to rotate. The two drive gears 601 mesh, and when the drive gears 601 rotate, they drive the two drive wheels 600 to rotate synchronously. The drive wheels 600 push the steel pipe 700 to move. When the steel pipe 700 passes the guide wheel B400, the hydraulic push rod B500 is activated to push the steel pipe 700 through the shaping bracket 501. This causes the steel pipe 700 to be pushed by the guide wheel B400 and the shaping bracket 501, thereby achieving... To achieve the bending purpose, the steel pipe 700 is continuously pushed, and two guide wheels A200 simultaneously clamp both sides of the steel pipe 700, continuously outputting power to bend the steel pipe 700. The fixed shaft A201 can slide inside the guide rail 101, thereby adjusting the position of the guide wheels A200 and changing the distance between the two guide wheels A200. This not only allows clamping the outside of steel pipes of different diameters, but also controls the bending angle of the steel pipe 700. By inserting the steel pipe 700 into two different guide wheels A200, different angles can be bent.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
