Description

Technical Field

[0001] This utility model belongs to the technical field of bending devices, and in particular, a bending device for air conditioning coils. Background Technology

[0002] In daily life, air conditioners are one of the devices that meet our production and living needs. Air conditioning coils create an indoor air environment that is comfortable for the human body, thereby maintaining a constant room temperature. They are usually bent to reduce their space requirements. However, different air conditioners have different specifications, and the required coil diameters vary. This makes it difficult for most bending devices to bend coils of different diameters. As a result, multiple bending devices are needed to bend coils of different diameters, which not only reduces the efficiency of bending air conditioning coils but also increases the cost.

[0003] For example, there is a Chinese publication number: CN211071396U, which describes a high-precision automatic steel pipe bending device: "It includes a worktable, a support unit for supporting the steel pipe, and a bending mechanism for bending the steel pipe; a vertical cylinder is provided on the worktable, and the support unit includes an end support member that is provided on the worktable through a support plate."

[0004] It is evident that the cited patent document has the problem of being inconvenient for bending coils of different diameters. Utility Model Content

[0005] The purpose of this invention is to provide a bending device for air conditioning coils to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending device for an air conditioning coil, comprising a workbench, a limiting roller provided on the top surface of the workbench via an L-shaped bracket, a drive motor fixedly mounted on the top surface of the workbench and directly below the bracket, a rotating block fixedly mounted laterally on the output shaft of the drive motor, an L-shaped movable block provided on one side of the rotating block, one side of the movable block penetrating into the inner cavity of the rotating block and slidingly adapted thereto, a fixing plate fixedly mounted laterally on the side of the movable block away from the rotating block and on the adjacent side, a bending roller for bending the coil provided between the two fixing plates, a sliding groove provided laterally on the top surface of the rotating block, a handle fixedly mounted on the top surface of the movable block located in the inner cavity of the rotating block, the handle passing through the sliding groove, a plurality of screw holes equidistantly provided on one side of the rotating block and one side of the movable block, and bolts threaded inside the two screw holes aligned with the positions of the rotating block and the movable block.

[0007] Preferably, the limiting roller and the bending roller are on the same horizontal plane, and the bottom surface of the movable block is provided with a horizontal groove.

[0008] Preferably, the inner cavity of the transverse groove is provided with an arc-shaped plate via two sliding rods, and the top surface of the worktable and the outer side of the drive motor is provided with an arc-shaped block.

[0009] Preferably, the top surface of the arc-shaped block is provided with an arc-shaped groove, and the arc-shaped plate is slidably disposed in the inner cavity of the arc-shaped groove.

[0010] Preferably, a placement plate for placing the coil is fixed on the top surface of the workbench and on one side of the limiting roller by a support frame.

[0011] Preferably, one side of the placement plate abuts against one side of the limiting roller, and a fixing box is symmetrically fixed on the top surface of the worktable and on one side of the placement plate.

[0012] Preferably, the top surfaces of the two fixed boxes are respectively provided with L-shaped movable frames via sliding columns and threaded shafts, and the ends of the two movable frames away from the fixed boxes are fixed with a number of stabilizing rollers for limiting the coils via a horizontal plate.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] The bending device for the air conditioning coil, through the configuration of a drive motor, rotating block, movable block, and fixed plate, allows the bending roller to make circumferential motion around the limiting roller, bending the coil placed on the periphery of the limiting roller. The movable block is further supported by the configuration of the arc plate, arc block, and arc groove.

[0015] Because the movable block and the rotating block slide and adapt to each other, the movable block can move within the rotating block's cavity, allowing the movable block to drive the bending roller to move. This changes the distance between the limiting roller and the bending roller, making it easier to bend coils of different diameters and thus improving the efficiency of bending air conditioning coils.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

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

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 5 The device shown is a bending device for an air conditioning coil, including a workbench 1. The bottom surface of the workbench 1 is equipped with support legs, and the top surface of the workbench 1 is provided with a limiting roller 2 by an L-shaped bracket. The center part of the periphery of the limiting roller 2 is recessed so that the air conditioning coil can be placed into the recessed part.

[0028] A drive motor 3 is fixedly mounted on the top surface of the workbench 1 and directly below the support. The drive motor 3 can rotate in both directions. A rotating block 4 is fixedly mounted horizontally on the output shaft of the drive motor 3. The rotating block 4 is located below the support. An L-shaped movable block 5 is provided on one side of the rotating block 4. The end of the movable block 5 away from the rotating block 4 is located on one side of the support. By turning on the drive motor 3, the drive motor 3 can drive the rotating block 4 to rotate, which in turn drives the movable block 5 to rotate. This allows the movable block 5 to make a circular motion around the output shaft of the drive motor 3 and the circumference of the limiting roller 2. At the same time, in conjunction with the forward and reverse rotation of the drive motor 3, the movable block 5 can rotate clockwise and counterclockwise.

[0029] One side of the movable block 5 extends into the inner cavity of the rotating block 4 and slides therewith. A sliding groove 8 is provided on the top surface of the rotating block 4. A handle 9 is fixed on the top surface of the movable block 5 in the inner cavity of the rotating block 4. The handle 9 passes through the sliding groove 8. By pulling the handle 9, the handle 9 can drive the movable block 5 to move in the inner cavity of the rotating block 4.

[0030] Both the rotating block 4 and the movable block 5 have several screw holes 10 at equal intervals on one side. Two screw holes 10 on the side of the rotating block 4 and the movable block 5 are aligned with each other and have bolts 11 threaded inside. After the movable block 5 is moved to a suitable position, one of the screw holes 10 on the side of the rotating block 4 will be aligned with one of the screw holes 10 on the side of the movable block 5. At this time, the bolts 11 are inserted into the two aligned screw holes 10 to fix the position of the movable block 5.

[0031] The movable block 5 has a fixed plate 6 horizontally fixed on one end away from the rotating block 4 and on the adjacent side. A bending roller 7 for bending the coil is provided between the two fixed plates 6. The limiting roller 2 and the bending roller 7 are on the same horizontal plane. When the coil is placed in the recessed part of the limiting roller 2, the handle 9 is pulled to move the movable block 5. This allows the movable block 5 to move the bending roller 7 towards the limiting roller 2 through the two fixed plates 6, so that the bending roller 7 can abut against the periphery of the coil. At this time, the bolt 11 is inserted into the two aligned screw holes 10 to bend the coil. The position of roller 7 is fixed. At this time, the drive motor 3 is turned on. The drive motor 3 drives the rotating block 4 and the movable block 5 to rotate, thereby driving the bending roller 7 to make a circular motion around the limiting roller 2. This allows the bending roller 7 to squeeze the coil and bend it, so that the coil can gradually fit against the periphery of the limiting roller 2, thus completing the bending of the coil. At the same time, the position between the movable block 5 and the rotating block 4 can be adjusted according to the actual situation, thereby adjusting the distance between the limiting roller 2 and the bending roller 7, which facilitates bending of coils of different diameters and improves the efficiency of bending air conditioning coils.

[0032] A placement plate 16 for placing the coil is fixed to the top surface of the workbench 1, located on one side of the limiting roller 2, via a support frame. The placement plate 16 is L-shaped, with one side of the placement plate 16 abutting against one side of the limiting roller 2. After the coil is placed in the recessed part of the limiting roller 2, the other part of the coil can be placed on the surface of the placement plate 16 for support. A fixing box 17 is symmetrically fixed to the top surface of the workbench 1, located on one side of the placement plate 16. The top surfaces of the two fixing boxes 17 are respectively slidably equipped with L-shaped movable frames 18 via sliding columns and threaded shafts. One end of the threaded shaft passes through the fixing box 17 and is fixed with a handle. The two movable frames 18... Several stabilizing rollers 19 for limiting the coil are fixed at one end away from the fixed box 17 via a horizontal plate. After the coil is placed on the top surface of the placement plate 16 and abuts against one side wall of the placement plate 16, the handle is turned to drive the threaded shaft to rotate, thereby driving the movable frame 18 to move. Since the two movable frames 18 are connected by a horizontal plate, the other movable frame 18 can be driven to move synchronously, so that the two movable frames 18 can drive the multiple stabilizing rollers 19 to move, so that the multiple stabilizing rollers 19 can abut against the coil placed on the top surface of the placement plate 16, thereby limiting the coil and reducing the swaying of the coil when bending.

[0033] The bottom surface of the movable block 5 has a horizontal groove 12. An arc-shaped plate 13 is slidably mounted inside the groove 12 via two sliding rods. An arc-shaped block 14 is located on the top surface of the worktable 1, outside the drive motor 3. An arc-shaped groove 15 is formed on the top surface of the arc-shaped block 14. The arc-shaped plate 13 is slidably mounted inside the arc-shaped groove 15. When the movable block 5 performs circular motion, it drives the arc-shaped plate 13 to move synchronously. The movement of the arc-shaped plate 13 occurs within the arc-shaped groove 15, thereby causing the arc-shaped block 14, the arc-shaped groove 15, and the arc-shaped plate 13 to move within the arc-shaped groove 15. The curved plate 13 supports the movable block 5, while the horizontal groove 12 and the sliding rod allow the curved plate 13 to move within the cavity of the horizontal groove 12. This ensures that when the curved plate 13 and the curved groove 15 support the movable block 5, the movable block 5 can also move within the cavity of the rotating block 4. One side of the curved plate 13 and the inner wall of the curved groove 15 are respectively provided with a through hole and a limiting rod. The through hole and the limiting rod are slidably matched to restrict the curved plate 13, ensuring that the curved plate 13 will always be within the cavity of the curved groove 15.

[0034] Working principle:

[0035] The bending device for the air conditioning coil places the coil to be bent on the surface of the placement plate 16, positioning the bending point between the limiting roller 2 and the bending roller 7. Turning the handle moves the stabilizing roller 19 via the threaded shaft and movable frame 18, allowing the stabilizing roller 19 to press against the coil and restrict its movement. Pulling the handle 9 moves the movable block 5 within the cavity of the rotating block 4, enabling the movable block 5 to move the bending roller 7 via the fixed plate 6. This changes the distance between the bending roller 7 and the limiting roller 2, thereby improving the bending effect. For bending coils of different diameters, after the bending roller 7 and the limiting roller 2 are both against the coil, the bolt 11 is inserted into the two aligned screw holes 10 to fix the position of the movable block 5. At this time, the drive motor 3 is turned on, and the drive motor 3 drives the rotating block 4 and the movable block 5 to make circular motion, which in turn makes the bending roller 7 move around the limiting roller 2 in a circular motion, so that the bending roller 7 can bend the coil and allow the coil to gradually fit against the periphery of the limiting roller 2, thereby completing the bending of the coil. This also facilitates bending coils of different diameters, thereby improving the efficiency of bending air conditioning coils.
