Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner condensate pipes, in particular to a bending device for air conditioner condensate pipes. Background Technique

[0002] The transfer of condensation heat. The main function of the air conditioner condensate pipe is to transfer the heat absorbed in the indoor unit of the air conditioner to the outdoor environment. When the indoor unit of the air conditioner absorbs the heat in the indoor air, the heat is transferred to the outdoor unit through the condensate pipe. The refrigerant in the condensate pipe is in a high-temperature and high-pressure state, and the heat is released to the outdoor air through the condensation effect, so that the indoor air can be cooled. During the processing of the air conditioner condensate pipe, bending is an essential step, and the condensate pipe is bent into the required shape through a bending device.

[0003] However, the existing bending device still has the problem that when bending the air conditioner condensate pipe, it is inconvenient to adapt and adjust the height for different specifications of air conditioner condensate pipes. When a larger or smaller air conditioner condensate pipe needs to be processed, it is inconvenient to adapt to the operation. For this reason, we propose a bending device for air conditioner condensate pipes. Content of the Utility Model

[0004] In view of the above problems, the utility model provides a bending device for air conditioner condensate pipes, which has an adjustment effect to prevent inconvenience in coordinating and adjusting the height during the processing of air conditioner condensate pipes. At the same time, it has a replaceable effect to prevent damage to the pressing mechanism after long-term use and affect the bending effect.

[0005] The technical solution of the utility model is: a bending device for air conditioner condensate pipes, including a bending device body, a pressing roller and a pushing frame. The pressing roller is arranged on the upper surface of the bending device body. The pushing frame is rotatably connected to the upper surface of the bending device body and is located on one side of the pressing roller. Both ends of the pressing roller are provided with mounting plates fixedly connected to the bending device body. A driving motor is fixed on the upper surface of one mounting plate. The output shaft of the driving motor is fixed with a threaded rod rotatably connected to the mounting plate. Both ends of the pressing roller are rotatably connected with fixing blocks located inside the mounting plate. One fixing block is threadedly connected to the threaded rod, and a limiting rod fixedly connected to the mounting plate is inserted into the other fixing block.

[0006] In a further technical solution, a first protective plate is arranged on one side of the surface of the pressing roller, and a second protective plate located on the surface of the pressing roller is arranged on the other side of the first protective plate. A convex plate is fixedly connected to the surface of the first protective plate, and a groove corresponding to the convex plate is opened on the surface of the second protective plate.

[0007] In a further technical solution, the contact surface between the fixing block and the limiting rod is in a smooth and fitting state, and the limiting rod is used to cooperate with the fixing block to improve the stability. Limiting blocks are fixedly connected to both sides of the fixing block.

[0008] In a further technical solution, a limiting groove corresponding to the limiting block is formed in the inner wall of the mounting plate, and the limiting block is located in the limiting groove.

[0009] In a further technical solution, a positioning rod fixed to the limiting groove is inserted into the surface of the limiting block, and the contact surface between the limiting block and the positioning rod is in smooth fit.

[0010] In a further technical solution, the convex plate is located in the groove, and limiting bolts are threadedly connected to both the convex plate and the groove.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. Through the mutual cooperation of the provided mounting plate, driving motor, threaded rod, and fixing block, the height of the pressing roller can be conveniently adjusted when operating on the air-conditioning condensate pipe. By driving the threaded rod to rotate through the driving motor, the threaded rod can drive the fixing block to move on the mounting plate in a threaded manner, achieving the effect of convenient adjustment, preventing the height of the pressing roller from being conveniently adjusted when bending the condensate pipe, so as to improve the applicability.

[0013] 2. Through the mutual cooperation of the provided first protective plate, second protective plate, convex plate, groove, and limiting bolt, the pressing roller can be conveniently protected and replaced during use. The surface of the pressing roller is protected by the cooperation of the first protective plate and the second protective plate, and then the convex plate and the groove can be adapted and screwed and installed with the limiting bolt for positioning, achieving the effect of convenient protection and replacement, preventing the surface of the pressing roller from being worn during long-term use and affecting the bending effect.

[0020] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0021] Embodiment:

[0022] As Figures 1-4 shown, an air conditioner condensate pipe bending device includes a bending device body 1, a pressing roller 2, and a pushing frame 3. The pressing roller 2 is arranged on the upper surface of the bending device body 1. The pushing frame 3 is rotatably connected to the upper surface of the bending device body 1 and is located on one side of the pressing roller 2. Both ends of the pressing roller 2 are provided with mounting plates 4 fixedly connected to the bending device body 1. A driving motor 5 is fixed on the upper surface of one mounting plate 4. The output shaft of the driving motor 5 is fixed with a threaded rod 6 rotatably connected to the mounting plate 4. Both ends of the pressing roller 2 are rotatably connected with fixing blocks 7 located inside the mounting plates 4. One fixing block 7 is threadedly connected to the threaded rod 6. A limiting rod 8 fixed to the mounting plate 4 is inserted into the other fixing block 7. The contact surface between the fixing block 7 and the limiting rod 8 is in smooth fit, and the limiting rod 8 is used to cooperate with the fixing block 7 to improve stability. Both sides of the fixing block 7 are fixedly connected with limiting blocks 9. Limiting grooves corresponding to the limiting blocks 9 are opened on the inner wall of the mounting plate 4. The limiting blocks 9 are located in the limiting grooves. A positioning rod 10 fixed to the limiting groove is inserted into the surface of the limiting block 9. The contact surface between the limiting block 9 and the positioning rod 10 is in smooth fit.

[0023] The working principle of the above technical solution is as follows:

[0024] When it is necessary to perform height adaptation adjustment operation on the pressing roller 2, first, the driving motor 5 can be started to operate to drive the threaded rod 6 to rotate, so that the threaded rod 6 can threadedly drive the movement of one fixing block 7 during rotation. And because the limiting rod 8 is inserted into the surface of the other fixing block 7, one fixing block 7 can move adaptively when receiving the threaded driving force. At this time, the fixing block 7 can make the limiting block 9 slide on the surface of the positioning rod 10 during movement. At this time, the arranged positioning rod 10 can improve the overall support effect, preventing the situation that when the pressing roller 2 operates on the air conditioner condensate pipe, the threaded rod 6 and the fixing block 7 are prone to bending under pressure, affecting the service life. At the same time, because the fixing block 7 is rotatably connected to the pressing roller 2, the pressing roller 2 can still rotate in cooperation when being driven. At this time, the pressing roller 2 adjusts to a suitable angle according to actual use, so as to cooperate with the pushing frame 3 to bend the air conditioner condensate pipe material, achieving the effect of convenient adjustment, and preventing the situation that when air conditioner condensate pipes with different diameters need bending operations, it is inconvenient to adjust the height, resulting in poor overall bending applicability.

[0025] In another embodiment, as Figure 1 and Figure 4As shown in the figure, a first protective plate 11 is provided on one side of the surface of the pressure roller 2, and a second protective plate 12 located on the surface of the pressure roller 2 is provided on the other side of the first protective plate 11. A convex plate 13 is fixedly connected to the surface of the first protective plate 11, and a groove 14 corresponding to the convex plate 13 is formed on the surface of the second protective plate 12. The convex plate 13 is located in the groove 14, and limiting bolts 15 are threadedly connected to both the convex plate 13 and the groove 14.

[0026] When the pressure roller 2 is in use, first, the first protective plate 11 can be held by hand and sleeved onto the surface of the pressure roller 2. Subsequently, the second protective plate 12 can be held by hand to drive the groove 14 to be sleeved onto the surface of the convex plate 13. At this time, the limiting bolt 15 is rotated to install and position the convex plate 13 and the groove 14. At this time, the first protective plate 11 and the second protective plate 12 provided can be adapted to protect the pressure roller 2 by the second protective plate 12, preventing the surface of the pressure roller 2 from being scratched and worn by the condenser tube during long-term use, which affects the bending and service life.

[0027] The above embodiments only represent the specific implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
