Description

Technical Field

[0001] The utility model belongs to the technical field of single-head pipe bending machines, in particular to a single-head pipe bending machine which is easy to adjust. Background Art

[0002] During the pipe processing process, a pipe bender is required for bending. When existing pipe benders process pipes of different sizes, threaded rods are usually used for support and movement. The support structure of the threaded rods is prone to connection gaps. When performing secondary processing on pipes of the same size, shaking and deviation are prone to occur, requiring re-clamping, fixing and calibration, which reduces the processing efficiency of the pipe.

[0003] Example (authorization announcement number is CN214768043U) A stable single-head pipe bending machine includes a universal wheel, a box, a driving motor, a driving rotating rod, a fixed plate, a torsion plate, a pipe bending plate, a locking bolt, a limit frame, a rotating rod, a driven roller, a connecting device, a base, an advance and retract screw rod, a torsion rod, a T-shaped slide groove, a T-shaped slider, an electric control box and a cabinet door. The end of the driving rotating rod is embedded in the interior of the driving motor, a fixing disk and a pipe bending disk are arranged on the wall of the driving rotating rod, and then the driven roller is rotated and connected to the interior of the limit frame through the rotating rod. A torsion disk is arranged on the wall of the pipe bending disk, and the pipe body is inserted into the torsion disk. When the driving motor is started by the electric control box, the pipe body is bent by the cooperation of the pipe bending disk and the limit frame. The torsion disk is arranged on the wall of the pipe bending disk, so that the pipe body is stabilized to prevent the pipe body from shifting during the pipe bending process. However, the device does not take into account the threaded structure of the threaded rod. When clamping, the connection gap of the threaded rod is very likely to shift. Processing pipes of the same size requires clamping, fixing and calibration, which reduces the processing efficiency of the pipes. Utility Model Content

The mounting block fixes the position of the damper, and the fixed block prevents the movable plate from falling off during the movement, thereby improving the functional and structural stability of the pipe bender.

DETAILED DESCRIPTION

[0024] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0027] In order to solve the problem that the threaded structure of the threaded rod clamps the pipe when the single-head pipe bender is easy to shake, the clamping position needs to be recalibrated, which is not convenient for secondary processing of pipes of the same size and reduces its processing efficiency, please refer to Figures 1 to 4 The structure of the device body is a processing table 1 and a clamping assembly 4. The processing table 1 is set to be in an inverted U-shaped shape and provide a supporting function. The top of the processing table 1 is rotatably connected to a bending plate 2 through an opened groove. The bending plate 2 is disc-shaped, which is convenient for realizing the relative rotation of the processing table 1 and the bending plate 2. A cylindrical clamping plate 3 is fixedly connected to the top of the bending plate 2 to fix the position of the clamping plate 3. The clamping assembly 4 includes a fixed plate 5 and a movable plate 6. The bottom end of the fixed plate 5 is fixedly connected to the bending plate 2 to fix the position of the clamping assembly 4 during transmission. A threaded rod 7 is fixedly connected to the side of the fixed plate 5. The threaded rod 7 is threadedly connected to a threaded pipe 8 so that the threaded rod 7 moves along the threaded path of the threaded pipe 8. The end face of the threaded pipe 8 is fixedly connected to the movable plate 6. The position movement of the movable plate 6 is realized during transmission, and the bottom surface of the movable plate 6 is slidably connected to the processing table 1 to prevent the movable plate 6 from rotating. A U-shaped limiting plate 16 for limiting the position of the pipe is fixedly connected to the top of the processing table 1. The limiting plate 16 provided provides a preliminary position fixation for the pipe.

[0028] The side of the movable plate 6 is rotatably connected with a clamping roller 9 through an opened groove, and the pipe is further clamped and fixed by the set clamping roller 9 and the clamping plate 3, so that when the bending plate 2 is rotated, the set clamping roller 9, the clamping plate 3 and the limit plate 16 realize the bending processing of the pipe. Since there is a gap at the threaded connection between the threaded rod 7 and the threaded tube 8, it is very easy to cause the clamping roller 9 to shake during the transmission process, which is not convenient for the secondary bending processing of the pipe of the same size. It is necessary to re-control the position of the clamping roller 9, which reduces the bending processing efficiency of the pipe bending machine for the pipe. The end face of the fixed plate 5 is fixedly connected with a plug-in block 12, and the side of the plug-in block 12 is slidably connected with a plug-in rod through an opened through groove 11. The provided plug-in block 12 fixes the moving path of the plug-in rod 11. The two end faces of the plug-in rod 11 are respectively fixedly connected to the limit block 13 and the connecting block 10. The end face of the plug-in block 12 is threadedly connected with a bolt 14. The end face of the bolt 14 is fixedly connected with a rubber block 24. The end of the rubber block 24 away from the bolt 14 overlaps the plug-in rod 11. The bolt 14 drives the rubber block 24 to overlap the plug-in rod 11, so as to fix the position of the plug-in rod 11, control the distance between the fixed plate 5 and the movable plate 6, prevent the clamping roller 9 from shaking during the transmission process, and thus improve the bending efficiency of the pipe bending machine for the pipe. The provided limit block 13 prevents the plug-in rod 11 from falling off, thereby improving the functional structural stability of the pipe bending machine.

[0029] The side of the connecting block 10 is fixedly connected to the movable plate 6 to fix the position of the connecting block 10. A driving motor 15 is installed at one end of the fixed plate 5 away from the threaded rod 7. The fixed end of the driving motor 15 is fixedly connected to the fixed plate 5. The set driving motor 15 provides power. The output shaft of the driving motor 15 is fixedly connected to the threaded rod 7, which is convenient for adjusting the position of the clamping roller 9 during transmission. A rotating motor 25 is installed at the bottom end of the processing table 1, so that the fixed end of the rotating motor 25 is fixed to the inner top wall of the processing table 1, and the top of the rotating motor 25 is fixedly connected to the bending plate 2, so that the output shaft of the rotating motor 25 rotates, which is convenient for realizing the bending processing of the pipe during transmission. The two side surfaces of the processing table 1 are fixedly connected with mounting blocks 17, and the side surfaces of the mounting blocks 17 are installed with dampers 18. The set mounting blocks 17 fix the position of the damper 18, and the moving end of the damper 18 is fixedly connected with a moving plate 20, and the end surface of the moving plate 20 is fixedly connected with a limiting rod 19.

[0030] The side of the limit rod 19 away from the damper 18 is slidably connected to a fixed block 22, and the two fixed blocks 22 are fixedly connected to the processing table 1 on the adjacent sides. The position of the limit rod 19 is moved during the transmission process, and the side of the limit rod 19 is slidably connected to a movable plate 20, so that the movable plate 20 moves along the path of the limit rod 19. The tops of the two movable plates 20 are fixedly connected to a U-shaped shielding plate 21, so that the tops of the two movable plates 20 are fixedly connected to a shielding plate 21. The shielding plate 21 is provided to provide a shielding and protective function to prevent the pipe from breaking when the pipe bending machine bends the pipe, causing a safety hazard, thereby improving the safety of the pipe bending machine. A buffer spring 23 is sleeved on the side of the limit rod 19, and the two end faces of the buffer spring 23 are respectively fixedly connected to the movable plate 20 and the fixed block 22. The buffer spring 23 is used in conjunction with the damper 18 to improve the shielding effect of the shielding plate 21.

[0031] The drive motor 15, damper 18, and rotating motor 25 are all prior art. Their working principles, sizes, and models are irrelevant to the functions of the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0032] How it works

[0033] When using the single-head pipe bender that is easy to adjust, the user places the pipe to be bent inside the limit plate 16 on the top of the processing table 1, so that the pipe is between the clamping plate 3 and the clamping roller 9. By starting the driving motor 15, the threaded pipe 8 moves along the threaded path of the threaded rod 7. During the transmission process, the distance between the clamping roller 9 and the clamping plate 3 is adjusted to clamp and fix the pipe. The rotating motor 25 is started to rotate the bending plate 2 to achieve the bending of the pipe, and the clamping roller 9 is prevented from being clamped due to the friction between the clamping plate 2 and the clamping roller 9. There is a gap in the threaded connection between the threaded rod 7 and the threaded tube 8, which causes shaking and affects the secondary bending processing of the pipe of the same size. The position of the plug-in rod 11 is fixed by the provided connecting block 10, and the side of the plug-in rod 11 is slidably connected with the plug-in block 12. The rubber block 24 is driven by the bolt 14 to contact the plug-in rod 11 to fix the position of the plug-in rod 11, and then the distance between the fixed plate 5 and the movable plate 6 is fixed to prevent the clamping roller 9 from shaking and deviating, thereby improving the bending processing efficiency of the pipe bender on the pipe.

[0034] The shielding plate 21 is provided to provide shielding and protection. When the pipe breaks due to bending, it is ejected to the side of the shielding plate 21, pushing the shielding plate 21 to move, and then the movable plate 20 moves along the path of the limit rod 19, generating a force on the buffer spring 23 and the damper 18, thereby improving the shielding and protection effect of the shielding plate 21. The end face of the limit rod 19 is provided to pass through the fixed block 22 to fix the moving path of the limit rod 19, thereby improving the structural stability of the parts of the pipe bending machine. The mounting block 17 is provided to fix the position of the damper 18, thereby improving the functional structural stability of the pipe bending machine, preventing the pipe from breaking during the bending process of the pipe by the pipe bending machine, causing safety hazards, and improving its safety in use.
