[0067] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] The embodiments of the present application provide a cutting device for electric power pipe bending, thereby solving the problem in the prior art that, in some cases, the obtained short pipe is difficult to bend to the target curvature or the size of the bent pipe after being bent to the target curvature is insufficient due to factors such as cutting accuracy and target length calculation errors, thereby improving the processing efficiency of electric power pipe bending.

[0069] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0070] In the prior art, when processing electric power pipe bends, it is necessary to first cut a short pipe of a target length from a pipe fitting, and then use a pipe bending device to bend the short pipe to obtain a pipe bent to a target curvature.

[0071] However, in some cases, due to factors such as cutting accuracy and target length calculation errors, the short tube obtained is difficult to bend to the target curvature or the size of the bent tube bent to the target curvature is insufficient, resulting in the need for re-cutting and bending, which affects the efficiency of line laying.

[0072] The research found that Figure 1-Figure 11 As shown, by setting a bending structure and a cutting structure, and integrating the cutting and bending processes, after the bending wheel bends the pipe to the required bending degree, the cutting structure cuts the bent pipe, thereby solving the problem in the prior art that, in some cases, due to factors such as cutting accuracy and target length calculation errors, the resulting short pipe is difficult to bend to the target curvature or the size of the bent pipe bent to the target curvature is insufficient, resulting in the need for re-cutting and bending, affecting the line laying efficiency.

[0073] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0074] like Figure 1-Figure 4 As shown, a cutting device for electric power pipe bending is used for processing a pipe fitting 4, comprising a processing table 1 and a bending structure 2 and a cutting structure 3 installed on the processing table 1;

[0075] The bending structure 2 and the cutting structure 3 are both controlled by a numerical control box 10;

[0076] The bending structure 2 includes a bending wheel 21 and a rotating column 22. The rotating column 22 is rotated by a driving motor and drives the bending wheel 21 to rotate. The bending angle of the pipe 4 matches the rotation angle of the bending wheel 21.

[0077] A limiting sheet metal 211 is provided on the side of the bending wheel 21, and a limiting groove is formed between the limiting sheet metal 211 and the bending wheel 21 for limiting the position of the pipe 4;

[0078] The cutting structure 3 includes a moving block 31, a driving member 32 and a cutting machine 35. The cutting machine 35 is installed on the moving block 31 and cuts the pipe 4.

[0079] The second driving member 32 is fixedly connected to the processing table 1, and a telescopic rod 321 is provided between the second driving member 32 and the moving block 31. The moving block 31 drives the telescopic rod 321 through the second driving member 32 to drive the moving block 31 to approach or move away from the bending structure 2;

[0080] The pipe 4 passes through the cutting structure 3 and the limiting groove under the action of the feeder;

[0081] After the bending structure 2 bends the pipe 4 , the cutting structure 3 cuts the bent pipe 4 .

[0082] By setting the bending structure 2 and the cutting structure 3, the pipe 4 fed by the feeder passes through the cutting structure 3 and is inserted into the limit groove formed on the bending structure 2. Then, the driving motor drives the rotating column 22 to rotate, thereby driving the bending wheel 21 set on the rotating column 22 to rotate. At this time, the rotation angle of the bending wheel 21 is the angle at which the pipe 4 needs to be bent. According to the required bending angle, the CNC box 10 is used to control the driving motor to drive the bending wheel 21 to rotate to a given angle;

[0083] After the bending wheel 21 bends the pipe 4 to the required bending degree, the cutting structure 3 cuts the bent pipe 4, thereby solving the problem in the prior art that, in some cases, due to factors such as cutting accuracy and target length calculation errors, the resulting short pipe is difficult to bend to the target curvature or the size of the bent pipe bent to the target curvature is insufficient, resulting in the need for re-cutting and bending, which affects the line laying efficiency.

[0084] like Figure 1-Figure 4 As shown, a rotating disk 33 is provided on one side of the moving block 31 close to the bending structure 2, and the rotating disk 33 is rotatably connected to the moving block 31 via a reduction motor;

[0085] The cutting machine 35 is fixedly connected to the rotating disk 33 via a mounting plate 34;

[0086] During cutting, the cutter 35 rotates with the center of the rotating disk 33 as a circle point, and the cutter 35 is started, the slice on the cutter 35 rotates, the slice approaches the pipe fitting 4, and provides an arc cutting force to the pipe fitting 4 to cut the pipe fitting 4.

[0087] The cutting machine 35 is rotatably connected to the moving block 31 through the rotating disk 33 to provide an arc-shaped cutting force for the cutting of the cutting machine 35. Compared with the traditional cutting machine 35 that moves in one direction toward the pipe 4 for cutting, the cutting machine 35 rotates and cuts with the center of the rotating disk 33 as the center point, which can effectively improve the uniformity of the force applied to the cutting of the pipe 4 and improve the cutting effect of the pipe 4.

[0088] like Figure 2-Figure 10 As shown, the side of the mounting plate 34 close to the rotating disk 33 is fixedly connected to the limiting column 1 341, the limiting column 2 342 and the limiting column 343;

[0089] The limiting column 343 and the limiting hole 313 are co-centered with the rotating disk 33;

[0090] The moving block 31 is provided with an arc groove 1 311 and an arc groove 2 312 on one side close to the rotating disk 33;

[0091] The second limiting column 342 is rotatably connected to the moving block 31 through the second arc groove 312;

[0092] The limiting column 1 341 is rotatably connected to the moving block 31 through the arc groove 1 311;

[0093] The arc groove 1 311 and the arc groove 2 312 are formed with the center of the rotating disk 33 as the circle point;

[0094] During cutting, the reduction motor drives the rotating disk 33 to rotate, and the cutter 35 rotates with the moving block 31 through the arc groove 1 311 and the arc groove 2 312 .

[0095] By providing the limiting column 1 341 , the limiting column 2 342 , the limiting column 343 , the arc groove 1 311 , the arc groove 2 312 and the limiting hole 313 , the stability of the cutting machine 35 when the rotating disk 33 rotates is improved, thereby improving the cutting effect of the cutting machine 35 on the pipe 4 .

[0096] like Figure 9-10 As shown, the arc groove 1 311 and the arc groove 2 312 are cocentric;

[0097] The distance between the inner diameter of the arc groove 1 311 and the center of the circle is greater than the distance between the inner diameter of the arc groove 2 312 and the center of the circle;

[0098] The distance between the first arc groove 311 and the center of the circle is greater than the diameter of the rotating disk 33 , and the distance between the second arc groove 312 and the center of the circle is less than the diameter of the rotating disk 33 .

[0099] By setting the arc groove 1 311 and the arc groove 2 312, utilizing the staggered setting of the arc groove 1 311 and the arc groove 2 312, and the limiting column 2 342 passing through the rotating disk 33 and plugged into the interior of the arc groove 2 312, and being rotatably connected with the arc groove 2 312, the stability of the cutting machine 35 is further improved when the rotating disk 33 rotates.

[0100] like Figure 1-Figure 4 As shown, a water tank 36 is installed on the moving block 31, and at least two water pipes 361 are provided on the water tank 36;

[0101] One of the water pipes 361 is higher than the placement height of the pipe 4 , and the outlet of the other water pipe 361 is located above the rotating disk 33 to flush the gap between the moving block 31 and the rotating disk 33 .

[0102] By providing at least two water pipes 361, the water pipes 361 are used to cool the metal during cutting, while ensuring smooth cutting operation.

[0103] like Figure 1 and Figure 4 As shown, the moving block 31 is provided with two symmetrically arranged second positioning members 37, and the second positioning member 37 is rotatably connected with a positioning wheel, and the two positioning wheels limit the pipe 4;

[0104] The second positioning member 37 moves closer to or away from the pipe member 4 through the third driving member 371 .

[0105] By arranging two second positioning members 37 on the moving block 31 and using the second positioning members 37 to limit the position of the pipe, the stability of the pipe 4 during bending and cutting can be ensured, and the bending and cutting effects of the pipe 4 can be improved.

[0106] like Figure 1-Figure 2 As shown, the bending structure 2 includes a turning table 24 and a base 25, and the end of the turning table 24 away from the moving block 31 is rotatably connected to the base 25 via a rotating shaft 241;

[0107] The bending wheel 21 is mounted on a turning table 24;

[0108] After cutting, the driving motor fixedly connected to the base 25 drives the rotating shaft 241 to rotate, the turning table 24 rotates 90 degrees, and the processed pipe 4 slides along the side wall of the bending wheel 21.

[0109] By setting up the turning table 24 and the base 25, the turning table 24 rotates under the action of the rotating shaft 241, and the bent end of the pipe 4 faces downward, which is convenient for the removal of the pipe 4 after processing, effectively improves the removal efficiency of the pipe 4 after processing, and can effectively improve the safety of workers when taking materials.

[0110] like Figure 1-Figure 2 As shown, a plurality of abutment members 251 are disposed on the rotating shaft 241, and each abutment member 251 is J-shaped;

[0111] When the bending wheel 21 is located above the turning platform 24 , the ends of the plurality of abutting members 251 away from the rotating shaft 241 are all in contact with the base 25 .

[0112] By providing a plurality of abutting members 251 , the overall stability of the turning platform 24 during operation is improved.

[0113] like Figure 1 As shown, the processing table 1 is supported by a plurality of support seats 11, and a collecting bin 12 is provided below the processing table 1, and the collecting bin 12 is located directly below the bending structure 2 and the cutting structure 3;

[0114] The processing table 1 is provided with a plurality of flow slots 13 which are connected to the collecting bin 12. The collecting bin 12 is used to collect the water flowing out of the water pipe 361.

[0115] A plurality of flow pipes are installed on the side of the collecting bin 12 for centralized discharge of the collected water flow inside the collecting bin 12 .

[0116] By providing the collecting bin 12, the wastewater generated during the cutting process is collected.

[0117] like Figure 3 As shown, the flip table 24 is provided with a positioning member 23 and a driving member 231, and a rotatably connected positioning wheel is provided inside the positioning member 23;

[0118] The driving member 231 drives the positioning member 23 to approach or move away from the pipe 4;

[0119] During bending, the positioning wheel installed on the positioning member 23 abuts against the pipe 4.

[0120] By providing a positioning member 23, the positioning member 23 is utilized to ensure the stability of the bending structure 2 during the bending process of the pipe 4.

[0121] like Fig.11 As shown, the bending wheel 21 is provided with a plurality of plug-in blocks 212 , and the rotating column 22 is provided with a plurality of slots 221 corresponding to the plug-in blocks 212 one by one. The bending wheel 21 is vertically plugged with the rotating column 22 via the plurality of plug-in blocks 212 and the plurality of slots 221 .

[0122] By vertically plugging the bending wheel 21 and the rotating column 22, the bending wheel 21 can be easily replaced while ensuring the horizontal direction of the bending wheel 21 is stable, and then the bending wheel 21 that is adapted to the outer diameter of the pipe 4 can be easily replaced for bending operations, thereby achieving the best bending effect.

[0123] During operation, the pipe 4 is fed by the feeder. After the pipe 4 passes through the cutting structure 3, the pipe 4 passes through the limiting groove formed between the bending wheel 21 and the limiting sheet metal 211. The limiting groove is used to limit the pipe 4. The feeding mechanism continues to feed the pipe 4 until the length of the pipe 4 passing through the limiting sheet metal 211 meets the straight pipe length requirement of one end of the electric power bend after processing.

[0124] The positioning member 23 is driven by the driving member 231, and the positioning wheel on the positioning member 23 abuts against the pipe 4 to limit the position of the pipe 4;

[0125] Afterwards, the two second positioning members 37 symmetrically arranged on the moving block 31 are moved closer to each other under the action of the third driving member 371, and the two positioning wheels on the two second positioning members 37 approaching each other limit the pipe 4;

[0126] At this time, the driving rotating column 22 rotates, thereby driving the bending wheel 21 fixedly plugged on the rotating column 22 to rotate, and the feeder continues to feed the material. The rotation of the bending wheel 21 is to perform a bending operation on the pipe 4 that continues to be fed;

[0127] The rotation of the bending wheel 21 is stopped until the rotation angle of the bending wheel 21 meets the bending angle requirement of the pipe 4;

[0128] After bending, the bent pipe 4 needs to be cut. Before cutting, the moving block 31 moves closer to or farther from the bending structure 2 under the action of the second driving member 32, and the moving block 31 drives the cutting machine 35 provided on the moving block 31 to move to a suitable position, so that the distance between the moving block 31 and the bending wheel 21 is the required length of the crown of the other end after the electric power bending process;

[0129] When cutting, the cutting machine 35 is started, and the slices on the cutting machine 35 rotate. At the same time, the reduction motor drives the rotating disk 33 to rotate. When the rotating disk 33 rotates, it can further drive the mounting plate 34 fixedly arranged on the rotating disk 33 to rotate, thereby driving the cutting machine 35 fixedly installed on the mounting plate 34 to rotate with the center of the rotating disk 33 as the center, so that the cutting machine 35 cuts the pipe 4 in the arc direction. When the rotating disk 33 drives the mounting plate 34 to rotate, the mounting plate 34 rotates with the moving block 31 through the arc groove 1 311 and the arc groove 2 312, thereby improving the stability of the mounting plate 34 during the rotation process, thereby improving the stability of the cutting machine 35 during the cutting process;

[0130] During the cutting process, the clean water or cutting fluid in the water tank 36 is added to the pipe 4 in the cutting process and the gap between the rotating disk 33 and the moving block 31 through the corresponding water pipe 361, which facilitates the cutting operation. The outflowing water flows into the interior of the collecting bin 12 through the flow slot 13 on the processing table 1. After the sewage in the collecting bin 12 accumulates to a certain amount, the sewage is discharged through the flow pipe provided on the collecting bin 12.

[0131] After the cutting is completed, the bent section of the pipe 4 is cut to form an electric bent pipe. The turning table 24 rotates under the action of the rotating shaft 241, and the straight pipe part of the electric bent pipe close to the cutting structure 3 is vertically downward and has a tendency to slide downward, so that it is convenient for workers to take the electric bent pipe formed between the bending wheel 21 and the limiting sheet metal 211 to complete the processing of the required electric bent pipe.

[0132] It should be noted that the entire process is controlled by the numerical control box 10 for feeding distance and bending angle, and electric power pipe bends with different bending degrees are processed according to actual needs;

[0133] At the same time, it should be noted that, according to actual needs, the bending wheel 21 that better fits the outer diameter of the pipe 4 can be replaced, and the curvature of the side of the bending wheel 21 that better fits the outer diameter of the pipe 4 can be selected to achieve a better bending effect;

[0134] When setting the second positioning member 37, the second positioning member 37 is as close to the slicer as possible to reduce the influence of the cutter 35 vibrating when the slicer cuts the pipe 4, which causes the cut section to be unstable.

[0135] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0136] 1. By setting a bending structure 2 and a cutting structure 3, the pipe 4 fed by the feeder passes through the cutting structure 3, and after the bending wheel 21 bends the pipe 4 to the required bending degree, the cutting structure 3 cuts the bent pipe 4, thereby solving the problem in the prior art that, in some cases, due to factors such as cutting accuracy and target length calculation errors, the obtained short pipe is difficult to bend to the target curvature or the size of the bent pipe bent to the target curvature is insufficient, resulting in the need for re-cutting and bending, which affects the line laying efficiency.

[0137] 2. The cutting machine 35 is rotatably connected to the moving block 31 through the rotating disk 33 to provide an arc-shaped cutting force for the cutting of the cutting machine 35. Compared with the traditional cutting machine 35 moving in one direction toward the pipe 4 for cutting, the cutting machine 35 rotates and cuts with the center of the rotating disk 33 as the center point, which can effectively improve the uniformity of the force applied to the cutting of the pipe 4 and improve the cutting effect of the pipe 4.
