Description

Technical Field

[0001] The utility model relates to the technical field of fin processing, in particular to a heat dissipation fin bending device. Background Technique

[0002] Fin processing is the core link in the production of finned tubes. Parameters such as the shape, thickness, and spacing of the fins will directly affect the heat transfer efficiency of the finned tubes. Fin processing equipment mainly includes punching machines, extrusion machines, rolling machines, welding machines, etc. The selection of these equipment should be determined according to the specific processing methods and materials. For example, for soft metals such as aluminum and copper, an extrusion machine or a rolling machine can be selected for processing; for hard metals such as stainless steel and carbon steel, a punching machine can be selected for processing. The heat dissipation fin bending device is an important tool for processing heat dissipation fins, which can bend the heat dissipation fins according to a predetermined shape and angle to meet different heat dissipation requirements. Most of the existing bending devices need to be adjusted manually, with low flexibility and accuracy, and there are certain limitations. Therefore, it is necessary to design a heat dissipation fin bending device to solve the problem. Summary of the Invention

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a heat dissipation fin bending device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A conveying component is arranged in the base. A push rod motor is arranged in the bending groove, and the output shaft of the push rod motor is connected with a support. A connecting frame is fixedly installed on the top of the support, and a bending head is placed on the top of the connecting frame. Three groups of fixed rods are arranged on the inner top walls of the frames, and a compression spring is connected and installed in the fixed rods. The bottom of the compression spring is fixedly installed with a telescopic rod, and the bottom of the telescopic rod is fixedly installed with a lifting frame. A pressing roller is rotatably connected in the lifting frame. The inner side walls of both sides of the frame are rotatably connected with a screw rod, and a lifting block is connected to the outside of the screw rod through a thread. A positioning block is fixedly installed on one side of the lifting block.

[0006] Preferably, there are several bending heads with various models. A connection port adapted to the bending head is formed on the top of the connecting frame, and a fastener is arranged on one side of the connecting frame, which can replace the bending head and is suitable for different bending states.

[0007] Preferably, the outer side of the pressing roller is made of rubber material, which can use the elasticity of the rubber to press the fins and play a protective role.

[0008] Preferably, the screw rod is a motor-driven electric screw rod, and the quantity and position thereof correspond to those of the lifting frame, and are used to control the lifting of the positioning block.

[0009] Preferably, positioning grooves adapted to the positioning blocks are formed on both sides of the lifting frame, and the height of the lifting frame is determined by the positioning blocks and the positioning grooves.

[0010] Preferably, the conveying assembly includes runners, the runners are rotatably connected to the base, a driving motor is connected to one side of one of the runners through the base, a connecting shaft is connected between two opposite runners, and a conveyor belt is connected between the runners on the same side, which can transport the fins and does not affect the bending work.

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

[0012] In the present utility model, the conveying assembly is used to transport the fins, adjust the positions of the fins, and the push rod motor is used to control the rising of the bending head to bend the fins. Meanwhile, when the bending work is carried out, the elastic forces of the compression spring and the pressing roller are used to press the fins, and the rising height of the pressing roller can be determined in advance by controlling the movement of the positioning block with the screw rod. When the fins are bent, due to the angle change, the pressing roller and the lifting frame in contact with the fins will rise until the lifting frame contacts the positioning block, which can effectively avoid the possibility of errors and is very practical.

[0018] Embodiment: Refer to Figures 1-3 , a heat dissipation fin bending device, including a base 1. A bending groove 2 is provided inside the base 1, and two frames 3 are fixedly installed on the top of the base 1. A conveying component 4 is arranged inside the base 1. A push rod motor 5 is arranged inside the bending groove 2, and the output shaft of the push rod motor 5 is connected with a support 6. A connecting frame 7 is fixedly installed on the top of the support 6, and a bending head 8 is placed on the top of the connecting frame 7. There are several bending heads 8, and they have various models. A connecting port adapted to the bending head 8 is opened on the top of the connecting frame 7, and a fastening component is arranged on one side of the connecting frame 7, which can replace the bending head 8 and is suitable for different bending states. Three groups of fixed rods 9 are arranged on the inner walls of the top of the frames 3, and a compression spring 10 is connected and installed inside the fixed rods 9. The bottom of the compression spring 10 is fixedly installed with a telescopic rod 11, and the bottom of the telescopic rod 11 is fixedly installed with a lifting frame 12. A pressing roller 13 is rotatably connected inside the lifting frame 12. The outer side of the pressing roller 13 is made of rubber material, which can press the fin by using the elasticity of the rubber and play a protective role. The inner walls of both sides of the frames 3 are rotatably connected with a screw rod 14. The screw rod 14 is a motor-driven electric screw rod, and the quantity and position correspond to the lifting frame 12, which is used to control the lifting of the positioning block 16. Positioning grooves adapted to the positioning block 16 are opened on both sides of the lifting frame 12. The height of the lifting frame 12 is determined by the positioning block 16 and the positioning grooves. The outer side of the screw rod 14 is threadedly connected with a lifting block 15, and a positioning block 16 is fixedly installed on one side of the lifting block 15. The conveying component 4 includes a runner 17, and the runner 17 is rotatably connected with the base 1. A driving motor 18 is connected to one side of one of the runners 17 through the base 1. A connecting shaft 19 is connected between two opposite runners 17, and a conveyor belt 20 is connected between the runners 17 on the same side, which can transport the fin and does not affect the bending work.

[0019] Working principle: When in use, the fin needs to be placed on the conveying component 4. The conveying component 4 controls the fin to move directly above the bending head 8 and makes its top contact with the pressing roller 13. Open the control of the screw rod 14 to lift the positioning block 16 to determine the rising height of the pressing roller 13. Open the push rod motor 5 to control the bending head 8 to rise to bend the fin. When the fin is bent, due to the angle change, the pressing roller 13 and the lifting frame 12 in contact with it will rise, and at the same time, the compression spring 10 will contract until the lifting frame 12 contacts the positioning block 16, then the bending work can be completed.
