Description

Technical Field

[0001] The utility model relates to a pipe processing device, in particular to an arc-shaped pipe processing device. Background Art

[0002] Pipe arc processing refers to the process of processing straight pipes into arc structures with specific curvatures through mechanical or heat treatment. This processing technology is widely used in architecture, automobiles, aerospace and other fields because the arc structure can provide better mechanical properties and aesthetic design.

[0003] To meet market demand, pipe curvature processing devices are designed to precisely process straight pipes into the desired curvature, accurately controlling the position and speed of the pipe during processing to ensure the quality and consistency of the final product. However, in the traditional bending process, when the pipe is subjected to bending force, the outer side is stretched, resulting in a thinner pipe wall, while the inner side is compressed, resulting in a thicker pipe wall. This change may not only affect the subsequent installation of the pipe, but may also cause the pipe to crack at the bend. This is especially true when cold bending is performed directly without pretreatment, as there is a certain probability of cracking, affecting the overall quality of the pipe.

[0004] Therefore, a pipe arc processing device is needed that is not easy to crack the pipe during bending, so as to solve the above technical problems. Utility Model Content

The controller 101 is installed on the right side of the top of the loading platform 1 by bolts, and the plate frame 2 is fixed to the rear side of the top of the loading platform 1. There are two first conveyor rollers 3 and a second conveyor roller 301 distributed inside the plate frame 2. The first conveyor roller 3 is connected by two front and rear connectors. The plate frame 2 is composed of a roller wheel in the middle, and two sliding rods 6 of different lengths are fixed to the rear side of the inner part of the plate frame 2, wherein the connecting head in the first conveying roller 3 is slidably connected to the plate frame 2, and a slide groove is provided on the plate frame 2 so that the first conveying roller 3 can slide up and down smoothly, wherein the connecting head in the first conveying roller 3 is slidably connected to the plate frame 2, and the second conveying roller 301 is rotatably connected to the plate frame 2, and the second conveying roller 301 is located below the first conveying roller 3 on the right side, and one side connecting head of the first conveying roller 3 on the left side is slidably connected to the longer sliding rod 6, and the first conveying roller 3 on the right side is slidably connected to the longer sliding rod 6. One side connector is slidably connected to the shorter sliding rod 6, two first motors 4 are installed on the top of the plate frame 2, the two first motors 4 are electrically connected to the controller 101, and the output shafts of the two first motors 4 are connected to threaded rods 5 of different lengths through couplings, the longer threaded rod 5 is threadedly connected to the other side connector of the left first conveyor roller 3, and the shorter threaded rod 5 is threadedly connected to the other side connector of the right first conveyor roller 3. A servo motor 7 is installed on the rear side of the plate frame 2, and the output shaft of the servo motor 7 is connected to the second conveyor roller 301. The bending block 8 is fixed to the upper part of the plate frame 2, and the bending block 8 is located between the two first conveying rollers 3. A heating chamber 12 is fixedly connected to the right side of the worktable 1, and a power supply 13 is installed at the bottom of the heating chamber 12. The power supply 13 and the controller 101 are electrically connected. A feed pipe 1302 is welded to the upper part of the heating chamber 12, and an induction coil 1301 is wound on the feed pipe 1302. The induction coil 1301 is made of copper wire with excellent conductive properties. The induction coil 1301 is electrically connected to the power supply 13. A cutting component is provided in the middle of the worktable 1, and a measuring component is provided on the left side of the worktable 1.

[0026] according to Figure 5 As shown, a sponge ring 1303 is also included, and the sponge ring 1303 is connected to the inside of the right opening of the heating chamber 12.

[0027] When using this device, the user first places the device on a flat ground, then starts the power supply 13 through the controller 101. The power supply 13 generates an alternating magnetic field in the induction coil 1301 through an alternating current. Subsequently, the pipe to be processed is fed into the opening of the heating chamber 12. A sponge ring 1303 is provided at the opening of the heating chamber 12 to perform basic cleaning on the pipe to be processed, facilitating subsequent operations. After the pipe enters the heating chamber 12, the induction coil 1301 generates eddy currents inside it. Due to the resistance of the metal, these eddy currents convert electrical energy into thermal energy, so that the pipe is fully heated. At this time, the staff pushes the pipe to the left between the first conveyor roller 3 and the second conveyor roller 301, and starts the first motor 4 through the controller 101. The output shaft of the first motor 4 located on the right side of the plate frame 2 drives the threaded rod 5 to rotate through the coupling, and then drives the first conveyor roller 3 to move up and down on the sliding rod 6. The height of the first conveyor roller 3 can be adaptively adjusted according to the diameter of the pipe to facilitate the clamping and pushing of pipes of different diameters. When the first conveyor roller 3 is adjusted to the appropriate height, the pipe is clamped, the first motor 4 is turned off, and the servo motor 7 is started. The output shaft of the servo motor 7 drives the second conveyor roller 301 to rotate counterclockwise. Under the rotation of the second conveyor roller 301, the pipe is conveyed to the left.

[0028] The pipe continues to be pushed to the left. When it contacts the first conveyor roller 3 on the left side of the plate frame 2, the controller 101 activates the first motor 4 on the left side of the plate frame 2. The output shaft of the first motor 4 on the left side drives the threaded rod 5 to rotate through the coupling, which in turn drives the first conveyor roller 3 on the left side to move up and down on the sliding rod 6, so that the pipe is bent into the desired curvature by the bending block 8. After the bending is completed, the staff can pull the pipe to the left to remove it.

[0029] according to Figure 1 and Figure 4 As shown, the cutting assembly includes a support rod 9, an electric push rod 10, a circular saw 11 and a second motor 1101. A support rod 9 is provided in the middle of the rear side of the inner wall of the frame 2. The electric push rod 10 is fixedly connected to the support rod 9. The end of the telescopic rod of the electric push rod 10 is fixedly connected to the circular saw 11. The second motor 1101 is installed on the right side of the circular saw 11. The second motor 1101 and the electric push rod 10 are both electrically connected to the controller 101.

[0030] according to Figure 1 and Figure 7 As shown, it also includes a fan 17 and a collection box 18. The fan 17 is installed on the top of the plate frame 2, and the fan 17 is located above the circular saw 11. The fan 17 is electrically connected to the controller 101, and the collection box 18 is placed in the middle of the workbench 1.

[0031] When the processed pipe needs to be cut, the controller 101 can be used to activate the electric push rod 10 and the second motor 1101. The output shaft of the second motor 1101 drives the circular saw 11 to rotate at high speed. The telescopic rod of the electric push rod 10 drives the circular saw 11 downward, thereby cutting the pipe. During the pipe cutting process, debris will fly out. To prevent the debris from affecting the operation of the device, the fan 17 can be activated. The fan 17 will blow the waste debris generated by the circular saw 11 when cutting the pipe into the collection box 18. The collection box 18 can be removed by pulling it forward and dumping it.

[0032] according to Figure 1 and Figure 6 As shown, the measuring assembly includes a support frame 14, a scale 15, a slider 16, a baffle 1601 and a third motor 1602. The support frame 14 is connected to the left side of the worktable 1 by bolts, the scale 15 is connected to the support frame 14 by bolts, the third motor 1602 is slidably connected to the scale 15, the output shaft of the third motor 1602 is connected to the baffle 1601, and the third motor 1602 is electrically connected to the controller 101.

[0033] In order to measure the length of the pipe that needs to be cut, when the pipe is bent and sent to the left by the first conveyor roller 3, the third motor 1602 can be started by the controller 101. The output shaft of the third motor 1602 drives the baffle 1601 to rotate clockwise to block the pipe. When the pipe moves, it will contact the baffle 1601 and push the slider 16 to the left to move on the scale 15, thereby driving the baffle 1601 and the third motor 1602 to slide on the scale 15. According to the distance that the baffle 1601 moves on the scale 15, the length of the pipe that needs to be cut can be judged. After the cutting is completed, the output shaft of the third motor 1602 will drive the baffle 1601 to reset counterclockwise and no longer block the pipe.

[0034] After the device is used, the controller 101 can be used to turn off each motor in turn.
