Description
Technical Field
[0001] This utility model relates to the field of pipe fitting processing technology, and more specifically to an inlaid roller mold for preventing bending pipes from damaging the surface of pipe fittings. Background Technology
[0002] In practical applications, pipe fittings need to be bent in different ways depending on the scenario to adapt to different spaces. For example, in some compact spaces, pipe fittings need to be bent multiple times to better meet the actual usage requirements.
[0003] Currently, fixed molds are usually used when bending pipe fittings. These molds are in direct contact with the surface of the pipe fittings, and the contact method is sliding friction, which can easily cause scratches on the surface of the pipe fittings. In addition, due to the lack of guiding design, the pipe fittings are prone to displacement or deformation during the bending process. Furthermore, the existing molds cannot adjust the bending size of the pipe fittings, making it difficult to meet the diverse needs of workers. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an inlaid roller mold for preventing the surface of pipe fittings from being damaged by bending, so as to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: an inlaid roller mold for preventing pipe bending from damaging the surface of pipe fittings, including a base, an mounting plate fixedly installed on the top of the base, an L-shaped plate fixedly installed on the top of the mounting plate, a cylinder fixedly installed on the top of the base, a bending roller provided on the front side of the L-shaped plate, two bending rollers symmetrically arranged, an adjustment component provided on the rear side of the L-shaped plate, and a lifting component provided at the output end of the cylinder.
[0006] Preferably, the adjustment assembly includes a fixed frame and a threaded rod. The fixed frame is fixedly installed on the mounting plate, and the threaded rod is rotatably installed on the fixed frame. Two threaded rods are symmetrically arranged, and an extension block is provided between the two threaded rods. The extension block is threadedly connected to the surface of the threaded rod, and a connecting frame is fixedly connected to the top of the extension block.
[0007] Preferably, one end of one of the threaded rods is fixedly connected to a rotating handle, and a power transmission component is installed between the two threaded rods, the power transmission component being used to transmit the rotational force of one threaded rod to the other threaded rod.
[0008] Preferably, the L-shaped plate has a through hole, and two through holes are symmetrically arranged. A guide rod is fixedly connected in the through hole, and a moving block is also arranged in the through hole. The moving block is sleeved on the surface of the guide rod. A connecting rod is arranged between the moving block and the connecting frame. One end of the connecting rod is hinged to the moving block, and the other end of the connecting rod is hinged to the connecting frame. The bending roller is rotatably installed on the front side of the moving block.
[0009] Preferably, the lifting assembly includes a receiving frame and a movable frame. The receiving frame is fixedly connected to the output end of the cylinder. A pressing roller is rotatably installed on the receiving frame. A docking groove is opened on the front side of the receiving frame. A guide rod is fixedly connected to the receiving frame. Two guide rods are symmetrically arranged. The movable frame is sleeved on the surface of the guide rod.
[0010] Preferably, a stabilizing frame is fixedly connected to the movable frame, and two stabilizing frames are symmetrically arranged. A strip block is provided on the front side of the movable frame, and a sliding column is fixedly connected to the front side of the movable frame. Two sliding columns are symmetrically arranged. The strip block is sleeved on the surface of the sliding column, and a docking block is fixedly connected to the strip block. The docking block matches the docking groove, and a compression spring is sleeved on the surface of the sliding column.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. The operator can place the pipe on top of the extrusion roller and the stabilizing frame. The cylinder output end extends upward. When the pipe just contacts the bending roller, the cylinder stops operating. Then, the stabilizing frame is pushed downward to release the support for the pipe. The cylinder output end continues to extend upward. The middle part of the pipe is squeezed and pushed upward by the extrusion roller, while the two sides of the pipe are blocked by the bending roller. The two sides of the pipe roll along the bending roller, and the bending roller rotates around its own axis, thereby completing the bending process of the pipe. This utility model avoids the sliding friction between the traditional mold and the pipe by contacting the pipe surface with the roller, thus preventing the surface of the pipe from being scratched. In addition, the roller plays a guiding role in the bending process, ensuring that the pipe moves according to the preset bending path. The roller also disperses the concentrated pressure during bending to multiple contact points, avoiding local deformation or damage to the pipe.
[0013] 2. The operator can manually turn the handle to make the threaded rod rotate around its own axis. The rotation of the threaded rod drives the extension block to move synchronously along the axis of the threaded rod. The connecting frame also moves synchronously under the traction of the extension block. While the connecting frame is moving, it can drive the two moving blocks to move synchronously in opposite or closer directions, so as to adjust the distance between the two bending rollers. This can adapt to the needs of different bending sizes and meet the diverse needs of the operator. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The inlaid roller mold for preventing the surface of pipe fittings from being pulled by bending pipes involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] This utility model provides an inlaid roller mold for preventing pipe bending from damaging the surface of pipe fittings. It includes a base 1, an mounting plate 2 fixedly installed on the top of the base 1, an L-shaped plate 3 fixedly installed on the top of the mounting plate 2, a cylinder 4 fixedly installed on the top of the base 1, a bending roller 5 provided on the front side of the L-shaped plate 3, two bending rollers 5 are symmetrically arranged, an adjustment component 6 is provided on the rear side of the L-shaped plate 3, and a lifting component 7 is provided at the output end of the cylinder 4.
[0025] Furthermore, the adjusting assembly 6 includes a fixed frame 61 and a threaded rod 62. The fixed frame 61 is fixedly mounted on the mounting plate 2, and the threaded rod 62 is rotatably mounted on the fixed frame 61. Two threaded rods 62 are symmetrically arranged, and an extension block 64 is provided between the two threaded rods 62. The interior of the extension block 64 is threadedly connected to the surface of the threaded rod 62, and a connecting frame 63 is fixedly connected to the top of the extension block 64. A rotating handle 68 is fixedly connected to one end of one threaded rod 62, and a power transmission component 67 is installed between the two threaded rods 62. The power transmission component 67 is used to transmit the rotational force of one threaded rod 62 to... Another threaded rod 62 has a through hole 31 through the L-shaped plate 3. There are two through holes 31 symmetrically arranged. A guide rod 32 is fixedly connected in the through hole 31. A moving block 66 is also provided in the through hole 31. The moving block 66 is sleeved on the surface of the guide rod 32. The moving block 66 and the guide rod 32 form a sliding guide fit along the axis of the guide rod 32. A connecting rod 65 is provided between the moving block 66 and the connecting frame 63. One end of the connecting rod 65 is hinged to the moving block 66, and the other end of the connecting rod 65 is hinged to the connecting frame 63. The bending roller 5 is rotatably installed on the front side of the moving block 66.
[0026] In use, the operator can manually rotate the handle 68 to make one threaded rod 62 rotate around its own axis. The rotation of one threaded rod 62 drives the other threaded rod 62 to rotate synchronously around its own axis through the power transmission component 67. The rotation of the threaded rod 62 drives the extension block 64 to move synchronously along the axis of the threaded rod 62 towards the L-shaped plate 3. The connecting frame 63 also moves synchronously under the traction of the extension block 64. The movement of the connecting frame 63 drives the two moving blocks 66 to move synchronously in opposite directions through the connecting rod 65. The two bending rollers 5 also move synchronously in opposite directions. If the operator rotates the handle 68 in the opposite direction, the two bending rollers 5 move synchronously towards each other, thereby adjusting the distance between the two bending rollers 5.
[0027] Furthermore, the lifting assembly 7 includes a receiving frame 71 and a movable frame 72. The receiving frame 71 is fixedly connected to the output end of the cylinder 4. A pressing roller 74 is rotatably mounted on the receiving frame 71. A docking groove 711 is provided on the front side of the receiving frame 71. A guide rod 75 is fixedly connected to the receiving frame 71. Two guide rods 75 are symmetrically arranged. The movable frame 72 is sleeved on the surface of the guide rod 75. A stabilizing frame 73 is fixedly connected to the movable frame 72. Two stabilizing frames 73 are symmetrically arranged. A strip block 7 is provided on the front side of the movable frame 72. 21. A sliding column 723 is fixedly connected to the front side of the movable frame 72. Two sliding columns 723 are symmetrically arranged. A strip block 721 is sleeved on the surface of the sliding column 723. A docking block 722 is fixedly connected to the strip block 721. The docking block 722 matches the docking groove 711. A compression spring 724 is sleeved on the surface of the sliding column 723. The elastic force of the compression spring 724 can drive the docking block 722 into the docking groove 711. The docking block 722 and the docking groove 711 cooperate with each other to fix the position of the stabilizing frame 73.
[0028] The working principle of this utility model is as follows: The operator places the pipe on top of the extrusion roller 74 and the stabilizing frame 73. The extrusion roller 74 and the stabilizing frame 73 jointly support the pipe. The output end of the cylinder 4 extends upward. Under the traction of the cylinder 4, the lifting component 7 and the pipe move upward as a whole. When the pipe just contacts the bending roller 5, the cylinder 4 stops operating. The operator pulls the strip block 721 by hand, so that the strip block 721 slides along the sliding column 723 in the direction away from the movable frame 72. The compression spring 724 contracts and increases its elasticity under the compression of the strip block 721. The strip block 721 moves and drives the docking block 722 to disengage from the docking groove 711. The operator then drags the movable frame 72 downward along the guide rod 75, so that the stabilizing frame 73 releases its support for the pipe. At this time, the pipe is located between the extrusion roller 74 and the two bending rollers 5.
[0029] As the cylinder 4 continues to extend upward, the middle part of the pipe is pushed upward by the extrusion roller 74, while the two sides of the pipe are blocked by the bending roller 5. The two sides of the pipe roll along the bending roller 5, and the bending roller 5 rotates around its own axis, thus completing the bending process of the pipe.
