Description

Technical Field

[0001] This utility model relates to the field of pipe bending technology, specifically to a pipe bender with an adjustment function. Background Technology

[0002] A pipe bender is a tool used to bend metal or plastic pipes, and is widely used in pipeline installation, automotive repair, construction, and other fields. It applies external force to bend the pipe at a desired angle in a specific location without flattening or damaging it.

[0003] Existing pipe bending technology is mainly divided into two processes: cold bending and hot bending. Cold bending uses mechanical force to bend the pipe at room temperature, which is highly efficient and energy-saving, but it has greater limitations on the bending radius and angle of the pipe, and is prone to deformation or damage. Hot bending softens the pipe at high temperature to achieve large radius and large angle bending. Although it can reduce deformation, it has high energy consumption, high pollution, and strict requirements on the pipe material.

[0004] Traditional pipe bending machines require changing clamps or adjusting complex mechanical structures to achieve pipe diameter adaptation, which is cumbersome and has poor adaptability. At the same time, some pipe bending equipment has a complex structure with insufficient connections between components and many redundant structures, which not only increases the manufacturing cost of the equipment, but also makes the equipment prone to failure during operation. Utility Model Content

[0005] To solve the above-mentioned technical problems, a pipe bender with adjustment function is provided, which solves the problems of cumbersome operation, poor adaptability and easy failure during operation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A pipe bender with an adjustable function includes a circular plate. A through groove is formed on the upper surface of the circular plate. A bolt is installed inside the through groove. A pipe bending assembly is rotatably installed at the center of the upper surface of the circular plate. Two connecting plates are arranged inside the pipe bending assembly. A mold is arranged between the two connecting plates. The mold is fixedly connected to the circular plate. A fixing rod is threaded on the outer surface of the mold. A moving rod is sleeved on the outer surface of the fixing rod.

[0008] The pipe bending assembly includes two connecting plates. A fixing plate is provided on the side of the two connecting plates away from the mold. The fixing plate is fixedly connected to both connecting plates. A lead screw is movably installed inside the fixing plate corresponding to the connecting plate. A limiting nut is sleeved on the outer surface of the lead screw and is fixedly connected to both connecting plates. A movable plate is fixedly installed at the end of the lead screw away from the fixing plate. A roller is rotatably installed inside the movable plate. A scale is fixedly installed on the upper surface of the connecting plate.

[0009] Preferably, a washer is fitted on the outer surface of the bolt corresponding to the circular plate, and two fastening nuts are threaded on the outer surface of the bolt corresponding to the circular plate, and the two fastening nuts are symmetrically distributed about the center line of the circular plate.

[0010] Preferably, a mold guide block is provided between the roller and the mold.

[0011] Preferably, a handle is fixedly installed at the end of the lead screw away from the fixed plate.

[0012] Preferably, the outer surface of the fixing rod is provided with a plurality of scale grooves, and the plurality of scale grooves are linearly distributed along the axial direction of the fixing rod.

[0013] Preferably, the side of the fixing plate corresponding to the lead screw has a connecting groove.

[0014] Preferably, the through groove is arc-shaped.

[0015] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets up a through groove, a fixing rod, and a bending tube assembly. The bolts in the through groove are used to limit the bending angle of the material, the fixing rod is used to measure the length of the material, and the bending assembly tightens the material while the operator pushes the bending assembly to process the material. Because the overall structure of the equipment is relatively simple, but retains the main functions required for bending, the production cost of the equipment is reduced. At the same time, since multiple parts do not operate simultaneously during equipment operation, the probability of equipment failure is reduced. Furthermore, due to the simple structure of the equipment, only the mold needs to be changed when bending different materials, and the required steps are simple, thereby improving the overall adaptability of the equipment.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figure 1-3 As shown, a pipe bender with adjustable function includes a circular plate 1. A through groove 2 is formed on the upper surface of the circular plate 1. A bolt 3 is installed inside the through groove 2. A pipe bending assembly 6 is rotatably installed at the center of the upper surface of the circular plate 1. Two connecting plates 601 are set inside the pipe bending assembly 6. A mold 7 is set between the two connecting plates 601. The mold 7 is fixedly connected to the circular plate 1. A fixing rod 4 is threaded on the outer surface of the mold 7. A moving rod 5 is sleeved on the outer surface of the fixing rod 4. A moving groove is formed on the side of the moving rod 5 near the mold. An adjusting bolt is set inside the moving groove. A fixing screw is threaded on the upper surface of the moving plate 5. The operator fixes the moving groove to the surface of the fixing rod 4 by rotating the fixing screw. The operator adjusts the equipment to adapt to various materials by rotating the adjusting bolt. The operator moves the moving rod 5 to a suitable position on the fixing rod 4 and adjusts the position of the bolt 3 on the through groove 2 according to the bending angle of the material. When processing the material, the operator places the material between the bending assembly and the mold 7 and fixes the material by the bending assembly. The material is bent by pushing the bending assembly.

[0022] The pipe bending assembly 6 includes two connecting plates 601. A fixing plate 602 is located on the side of each connecting plate 601 away from the mold 7. The fixing plate 602 is fixedly connected to both connecting plates 601. A lead screw 603 is movably installed inside the fixing plate 602 corresponding to the connecting plate 601. A limiting nut 604 is sleeved on the outer surface of the lead screw 603, and the limiting nut 604 is fixedly connected to both connecting plates 601. The limiting nut 604 limits the lead screw 603, and both the limiting nut 604 and the lead screw 603 have a self-locking function, thereby preventing the material from coming out of the fastened state during processing. A movable plate 605 is fixedly installed at the end of rod 603 away from fixed plate 602. A roller 606 is rotatably installed inside the movable plate 605. A dial 607 is fixedly installed on the upper surface of connecting plate 601. The dial 607 facilitates the positioning of bolt 3 by the operator and allows the operator to directly observe the bending angle. The operator places the material between roller 606 and mold 7 and fixes the material by rotating screw 603. By pushing the bending tube assembly 6 as a whole, the material is bent. When the bending tube assembly 6 contacts bolt 3, the processing is completed and the pushing stops.

[0023] like Figure 1-2As shown, a washer 8 is fitted on the outer surface of the bolt 3 corresponding to the circular plate 1, and two fastening nuts 9 are threaded on the outer surface of the bolt 3 corresponding to the circular plate 1. The two fastening nuts 9 are symmetrically distributed about the center line of the circular plate 1. By adjusting the fastening nuts 9, the operator controls the movement and fixation of the bolt 3 in the through groove 2. By adjusting the position of the bolt 3 in the through groove 2, the operator controls the bending angle of the material.

[0024] like Figure 1-3 As shown, a mold guide block 10 is provided between the roller 606 and the mold 7. The operator places the material between the mold 7 and the mold guide block 10, and rotates the screw 603 to make the roller 606 press the mold guide block 10, thereby fixing the material between the mold 7 and the mold guide block 10. When bending the material, the roller 606 presses the material along the mold guide block 10, thereby bending the material.

[0025] like Figure 1-3 As shown, a handle 11 is fixedly installed at the end of the lead screw 603 away from the fixed plate 602. The handle 11 provides the operator with a better point of leverage and grip, making the rotation of the lead screw 603 more stable and controllable. When it is necessary to inspect, repair or replace components such as the lead screw 603 and the limit nut 604, the operator can easily rotate the lead screw 603 through the handle 11 to adjust the relevant components to a position that is easy to operate, making maintenance work convenient.

[0026] like Figure 1-3 As shown, the outer surface of the fixed rod 4 is provided with several scale grooves 12, which are linearly distributed along the axial direction of the fixed rod 4. When the operator measures the material before processing, he moves the moving rod 5 to the position of the corresponding scale groove 12, and the material is quickly measured by the moving rod 5, reducing the steps required for measurement.

[0027] like Figure 1-3 As shown, a connecting groove 13 is provided on the side of the fixing plate 602 corresponding to the lead screw 603. The connecting groove 13 limits the lead screw 603, and at the same time, the connecting groove 13 cooperates with the handle 11 to limit the lead screw 603.

[0028] like Figure 1-3 As shown, the through groove 2 is set in an arc shape. The staff adjusts the bolt 3 in the through groove 2 according to the required bending angle of the material. The arc-shaped through groove 2 provides the movement trajectory for the bolt 3, which facilitates the determination of the bending angle of the material.

[0029] Working principle: Based on the required bending angle and length of the material, the operator controls the movement and fixation of the bolt 3 in the through groove 2 by adjusting the fastening nut 9. Then, the moving rod 5 is moved to the position of the corresponding scale groove 12. The material is quickly measured by the moving rod 5. The operator places the material of suitable length between the mold 7 and the mold guide block 10. The screw 603 is rotated by the handle 11. The screw 603 moves through the limit nut 604, so that the roller 606 fixes the material. At the same time, part of the material enters the limit groove 10. By pushing the bending tube assembly 6, the roller 606 squeezes the material along the mold guide block 10, thereby bending the material. When the bending tube assembly 6 contacts the bolt 3, the processing stops. At this time, the material meets the processing requirements.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
