Description

Technical Field

[0001] This utility model relates to the field of pipe bending equipment technology, and in particular to a pipe bending device. Background Technology

[0002] A manual pipe bending device is a relatively simple, manually operated specialized tool primarily used for cold bending of metal pipes (such as steel, copper, and aluminum pipes) in situations where power is scarce or high flexibility is required. Its core applications include small- to medium-scale pipe installations (such as plumbing, gas, hydraulic, and pneumatic pipelines), automotive repair, furniture manufacturing, equipment maintenance, and on-site construction, and it is particularly suitable for small-batch production or single-piece custom processing.

[0003] Manual pipe bending devices typically have a single fixed auxiliary roller that moves close to the outside of the pipe during bending. This roller, in conjunction with the bending die, forms a three-point force application, guiding the pipe to bend smoothly along the die's contour. However, because the auxiliary roller has a small contact area with the pipe and is in direct contact, uneven force application can easily occur during manual bending, affecting the pipe's deformation. Furthermore, the adjustment process is complex when changing to pipes of different sizes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pipe bending device. By setting a pressure plate in contact with the pipe and setting a pressure groove in the pressure plate, it can cooperate with the loading groove on the fixed wheel to ensure the stability of the pipe position and protect the pipe during the bending process.

[0005] According to an embodiment of the present invention, a pipe bending device includes a base with a flat table surface. A fixed wheel is fixedly mounted on the table surface, the axis of the fixed wheel being perpendicular to the table surface. A loading groove is provided around the side of the fixed wheel. A bracket is rotatably connected to the table surface. An abutment component is provided on the side of the bracket near the fixed wheel. A pressure plate tangent to the fixed wheel is movably mounted between the abutment component and the fixed wheel. The side of the pressure plate away from the fixed wheel abuts against the abutment component. A pressure groove is provided on the side of the pressure plate near the fixed wheel. A blocking component is fixedly mounted on one side of the loading groove.

[0006] Preferably, a shaft perpendicular to the platform is fixedly provided on the platform, a fixed wheel is coaxially provided on the shaft, a positioning rod passing through the fixed wheel is fixedly connected to the platform, and a blocking assembly located outside the loading groove is detachably connected to the positioning rod.

[0007] More preferably, a stud parallel to the positioning rod is fixed on the fixed wheel, and the blocking assembly includes an n-shaped blocking plate. One side of the blocking plate is provided with two mounting holes corresponding to the positioning rod and the stud. The blocking plate is fixed to the side of the fixed wheel by a fixing nut.

[0008] More preferably, the bracket includes two rotating plates rotatably connected to the shaft and arranged radially thereon, a fixed plate fixed on the rotating plates, the two rotating plates being arranged in parallel and respectively located on both sides of the fixed wheel, and the abutting component and the pressure plate being provided between the two rotating plates.

[0009] More preferably, the abutment assembly includes an abutment wheel rotatably disposed between the two rotating plates.

[0010] In a further preferred embodiment, a slide block that can move along the length direction is slidably provided between the two rotating plates, the fixed plate is provided with a screw hole and an adjusting screw is threaded on it, the adjusting screw is rotatably connected to the slide block, and the abutment wheel is rotatably disposed on the slide block.

[0011] In a further preferred embodiment, the side of the fixed wheel is provided with a surrounding limiting groove, the bottom of the limiting groove is provided with the loading groove, and the pressure plate is disposed in the limiting groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This application provides a pressure plate tangent to the fixed wheel. The fixed wheel and the pressure plate are respectively provided with a loading groove and a pressure groove. When the abutting component applies force to the pressure plate, the pressure groove and the loading groove clamp the pipe in the middle, so that the pipe is not easy to deviate during the bending process. By contacting the pipe with the pressure groove, the damage deformation of the pipe surface during the bending process can be reduced.

[0014] In this application, the abutment wheel can be easily adjusted to adjust the distance between itself and the fixed wheel, and the blocking component can also be quickly installed and disassembled, making it more adaptable to pipes of different diameters. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] This utility model provides a pipe bending device, including a base 1 with a flat table 101, a fixed wheel 2 fixedly mounted on the table 101, and multiple mounting through holes on the side of the base 1 for fixing to a work platform by bolts. The axis of the fixed wheel 2 is perpendicular to the table 101, and a surrounding loading groove 201 is provided on the side of the fixed wheel 2. A bracket 3 is also rotatably connected to the table 101, and the rotation axis of the bracket 3 is coaxial with the fixed wheel 2. An abutment component 4 is provided on the side of the bracket 3 near the fixed wheel 2. A pressure plate 5 tangent to the fixed wheel 2 is movably mounted between the abutment component 4 and the fixed wheel 2. The side of the pressure plate 5 away from the fixed wheel 2 abuts against the abutment component 4. A pressure groove 501 is provided on the side of the pressure plate 5 near the fixed wheel 2. A blocking component 6 is fixedly mounted on one side of the loading groove 201.

[0020] During the pipe bending process, one end of the pipe is blocked by the blocking component 6, and the other end is located between the pressure groove 501 and the loading groove 201. When the bracket 3 is rotated, the contact component 4 exerts a force on the pressure plate 5, and the pressure plate 5 drives the pipe to bend.

[0021] Specifically, such as Figure 1 As shown, a shaft 102 perpendicular to the platform 101 is fixedly provided on the platform 101. The fixed wheel 2 is coaxially provided on the shaft 102. A positioning rod 103 passing through the fixed wheel 2 is fixedly connected to the platform 101. There is a gap between the positioning rod 103 and the shaft 102 so that the fixed wheel 2 cannot rotate. The blocking component 6 located outside the loading groove 201 is detachably connected to the positioning rod 103. The blocking component 6 can be replaced when dealing with pipes of different diameters.

[0022] To facilitate quick disassembly and replacement of the blocking assembly 6, in a further embodiment, a stud 104 parallel to the positioning rod 103 is fixedly provided on the fixed wheel 2. The blocking assembly 6 includes an n-shaped blocking plate 601. Two mounting holes 602 corresponding to the positioning rod 103 and the stud 104 are provided on one side of the blocking plate 601. The blocking plate 601 is fixed to the side of the fixed wheel 2 by a fixing nut 105. Under the action of the stud 104 and the positioning rod 103, the blocking plate 601 is fixed in position, which can stably restrict one end of the pipe.

[0023] Specifically, the bracket 3 includes two rotating plates 301 rotatably connected to the shaft 102 and arranged radially thereon, and a fixing plate 302 fixed on the rotating plates 301. The two rotating plates 301 are arranged in parallel and are respectively located on both sides of the fixing wheel 2. The abutting component 4 and the pressure plate 5 are provided between the two rotating plates 301.

[0024] like Figure 2 As shown, the abutting assembly 4 includes an abutting wheel 401 rotatably disposed between the two rotating plates 301;

[0025] To accommodate bending operations of different pipe materials, in a further embodiment, a slide block 402 that can move along its length is slidably provided between the two rotating plates 301. The slide block 402 has sliding grooves on both sides, which cooperate with the rotating plates 301 on both sides, so that the slide block 402 can only move along the rotating plates 301. The fixed plate 302 has screw holes and is threaded with an adjusting screw 403. The adjusting screw 403 is in the same direction as the movement of the slide block 402. The adjusting screw 403 is rotatably connected to the slide block 402. The abutment wheel 401 is rotatably mounted on the slide block 402.

[0026] By rotating the adjusting screw 403, the distance between the contact wheel 401 and the fixed wheel 2 can be changed, thereby adjusting the distance between the pressure plate 5 and the fixed wheel 2, so that the pressure groove 501 and the loading groove 201 can accommodate pipes of different diameters.

[0027] To improve the stability of the pressure plate 5, in a further embodiment, the side of the fixed wheel 2 is provided with a surrounding limiting groove 202, and the bottom of the limiting groove 202 is provided with the loading groove 201. The pressure plate 5 is set in the limiting groove 202. Under the action of the limiting groove 202, the pressure plate 5 is not easy to deviate, thereby improving the stability of the pipeline during the bending process.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
