Description

Technical Field

[0001] This utility model relates to the field of finned evaporator manufacturing technology, and in particular to a horizontal tube bending machine for finned evaporators. Background Technology

[0002] The finned evaporator is a core component of a refrigeration system. It achieves cooling by absorbing heat through refrigerant evaporation and mainly consists of fins, a base tube, and an air duct. Its core structure involves adding a large number of fins to the outer surface of a copper or aluminum tube, significantly increasing the air contact area and improving heat exchange efficiency.

[0003] As a crucial component of the evaporator, the base tube is often bent into an S-shape to maximize flow volume within a limited space. Therefore, a horizontal tube bending machine is used in the production of finned evaporators to bend the base tube. However, existing horizontal tube bending machines are mostly manually operated, requiring manual handling of the tube and pushing it according to the bending position. Due to the S-shaped bending requirements, manual operation not only involves pushing the tube but also rotating and adjusting it. This means that any error in rotation during bending can easily affect the formation of the base tube in the finned evaporator. To address this, we propose a horizontal tube bending machine for finned evaporators. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example

[0025] Reference Figures 1-4 A horizontal tube bending machine for finned evaporators includes an operating table 1. Support legs 24 are installed at the bottom corners of the operating table 1. An mounting plate 25 is fixed to the bottom of the support legs 24. The mounting plate 25 has mounting holes to support the operating table 1. In actual use, bolts can be taken and passed through the mounting holes to install and fix the operating table 1.

[0026] A circular groove 2 is provided in the middle of the operating table 1. A support 3 is provided in the middle of the circular groove 2. The support 3 is fixed to the circular groove 2 by a connecting bracket 4, so that the periphery of the support 3 is open.

[0027] A limiting wheel 5 is provided above the support base 3. The limiting wheel 5 is rotatably connected to the support base 3 via a rotating shaft, and an arc groove is provided along the side of the limiting wheel 5 so that the pipe can fit more closely to the limiting wheel 5 after the pipe comes into contact with it.

[0028] like Figure 2As shown, a housing 10 with a top opening is provided on the side of the circular groove 2 away from the connecting frame 4. The housing 10 is arranged in the radial direction of the circular groove 2, and a connecting seat 14 is installed at one end of the housing 10. A drive shaft 15 is fixed through the connecting seat 14. The drive shaft 15 is coaxial with the circular groove 2, and the top of the drive shaft 15 is rotatably mounted on the support seat 3. A second drive motor 16 is installed at the bottom of the drive shaft 15. The second drive motor 16 is fixed to the connecting frame 4 through a bracket. The second drive motor 16 provides power for the rotation of the housing 10, that is, it allows the housing 10 to perform arc-shaped reciprocating motion below the circular groove 2 with the drive shaft 15 as the axis.

[0029] In order to improve the rotational stability and stress strength of the chassis 10, a second annular slide rail 17 is installed at the bottom of the operating table 1. The second slide rail 17 is coaxially arranged with the circular groove 2, and a second slider 18 is slidably installed on the second slide rail 17. The second slider 18 is fixed to the chassis 10 and provides guidance for the rotation of the chassis 10.

[0030] like Figure 3 and Figure 4 As shown, a lead screw 9 is provided inside the housing 10. The end of the lead screw 9 is rotatably connected to the end of the housing 10. A first drive motor 11 is installed on the end of the lead screw 9 away from the second drive motor 16. The first drive motor 11 is fixed on the housing 10. A movable seat 8 is connected to the lead screw 9 by a threaded nut. A connecting shaft 7 is rotatably installed on the top of the movable seat 8. A transmission wheel 6 is installed on the top of the connecting shaft 7. The transmission wheel 6 corresponds to the limit wheel 5. An arc-shaped groove is opened along the side of the transmission wheel 6. The arc-shaped groove allows the pipe to fit more closely to the transmission wheel 6 when in contact. The first drive motor 11 provides power for the rotation of the lead screw 9. As the lead screw 9 rotates, it can drive the movable seat 8 to perform linear reciprocating motion. This can drive the transmission wheel 6 to adjust its distance from the limit wheel 5, so as to adjust the distance between the transmission wheel 6 and the limit wheel 5 according to the curvature of the pipe required in actual use.

[0031] Specifically, the connecting frame 4 is configured such that the frontal projection of the circular groove 2 is arc-shaped, while the frontal projection of the chassis 10 in its initial position is located in the middle of the circular groove 2. Furthermore, the slots on both sides of the chassis 10 are symmetrical, meaning that the chassis 10 can rotate to both sides under the action of the second drive motor 16. In use, the pipe is taken and passed between the limiting wheel 5 and the transmission wheel 6. As the pipe moves linearly, the transmission wheel 6 will bend the pipe under the rotation of the chassis 10. After bending it to 90°, the chassis 10 will drive the transmission wheel 6 back to its initial position. Starting from the initial position, the tube continues to move in a straight line while the casing 10 performs a second bend in the same direction, bending the tube into a U-shape. Then, as the tube moves again, the casing 10 begins to deflect in the opposite direction, thus forming the first S-shaped tube bend through two bends as described above. Repeating the above process produces the base tube for the desired finned evaporator. During this process, there is no need to flip the tube; simply maintaining the straight-line movement of the tube improves the convenience and reduces effort in the bending process.

[0032] Furthermore, strip-shaped first slide rails 12 are installed on both sides of the inner wall of the chassis 10. First sliders 13 are slidably installed on the first slide rails 12. The first sliders 13 are fixed to the movable seat 8 and guide the linear movement of the movable seat 8, thereby ensuring the stability of the movable seat 8 during linear movement.

[0033] It should be noted that, as Figure 1 As shown, a slot 22 is provided on one end of the operating table 1 away from the connecting frame 4. A support wheel 23 is provided in the slot 22. The end of the support wheel 23 is rotatably connected to the inner wall of the slot 22, which can provide support for the pipe moving in a straight line and improve the stability of the pipe when it moves.

[0034] It should be further explained that a U-shaped frame 19 with an opening facing downwards is provided above the operating table 1. The end of the U-shaped frame 19 is fitted with the top of the operating table 1 with a clearance. The top of the rotating shaft of the limiting wheel 5 is rotatably mounted on the U-shaped frame 19. A sliding groove 20 is provided on the side of the U-shaped frame 19 away from the connecting frame 4. A third slider 21 is slidably installed in the sliding groove 20. The third slider 21 is rotatably connected to the transmission wheel 6 through a rotating shaft, providing limiting support for the top of the transmission wheel 6 and the top of the limiting wheel 5, thereby reinforcing the transmission wheel 6 and the limiting wheel 5 and improving their service life.

[0035] Specifically, a control box 26 is installed on one side of the operating console 1. The control box 26 contains a controller, which is connected to the first drive motor 11 and the second drive motor 16 via wires. In actual use, the controller is a PLC logic controller, a control motherboard, and a control host. In addition, a touch screen display is installed on the outer wall of the control box 26. The touch screen display is connected to the controller via wires to control the operation of the horizontal pipe bending machine.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
