Description

Technical Field

[0001] This utility model relates to the field of heat dissipation copper pipe bending technology, specifically to a bending device for heat dissipation copper pipes. Background Technology

[0002] A heat dissipation copper pipe bending device is a specialized device used to bend heat dissipation copper pipes to specific angles and shapes.

[0003] Chinese patent CN218486946U discloses a bending device for processing copper tubes in radiators, including a bending device body, a first baffle, and a second baffle. Two first baffles are rotatably fixed to the upper surface of the bending device body. By setting a first clamping plate, when the copper tube needs processing, the second clamping plate can be held and applied force away from the first clamping plate to unfold it. At this time, the copper tube is placed between the first and second clamping plates. Releasing the force on the second clamping plate allows it to slide on the surface of a fixed rod under the pressure of a first spring. When the second fixed plate moves, it applies force to the copper tube using the second clamping plate, which can cooperate with the first clamping plate to limit the movement of the copper tube. However, this device still has the following problems during use:

[0004] The angle of the bending section of this device is fixed. When it is necessary to bend copper heat dissipation pipes of different diameters, it is also necessary to change the corresponding parts of the bending section, which is inconvenient.

[0005] Based on this, the present invention designs a bending device for heat dissipation copper pipes to solve the above problems. Utility Model Content

[0040] In this invention, the copper pipe conveying device moves from the rear of the base plate 1 to the right side of the positioning component. Then, the movable component controls the simultaneous movement of the rotary auxiliary bending component and the linear auxiliary bending component towards the copper pipe until the left end of the copper pipe is in contact with the positioning component, and the right end is in contact with both components. Subsequently, the rotating table 2 drives the positioning component and the rotary auxiliary bending component to rotate. At this time, the positioning component and the rotary auxiliary bending component rotate simultaneously, bending the copper pipe.

The left ends of the first fixed plate 53 and the first movable plate 54 are both provided with arc-shaped grooves 516.

[0047] The linear auxiliary bending assembly includes a second fixed plate 55 and a second movable plate 56. The second movable plate 56 is fixedly installed in the middle of the U-shaped support frame 57 of the third adjustment assembly. The two second movable plates 56 are symmetrically distributed on the upper and lower sides of the U-shaped support frame 57 of the third adjustment assembly, and the two second movable plates 56 are threadedly connected to the bidirectional lead screw 58 of the third adjustment assembly. The left ends of the second fixed plate 55 and the second movable plate 56 are also provided with arc-shaped grooves 516.

[0048] The movable components include a first cylinder 511, a linear guide rod 512, and a second cylinder 513. The first cylinder 511 is fixedly mounted on the upper rear side of the connecting frame 4 via a bracket. The output end of the first cylinder 511 is fixedly connected to the right end of the U-shaped support frame 57 of the second adjustment component. The linear guide rod 512 is fixedly mounted on the upper end of the connecting frame 4 via a bracket. The U-shaped support frame 57 of the second adjustment component is slidably connected to the linear guide rod 512. The second cylinder 513 is fixedly mounted on the upper rear side of the base plate 1. The output end of the second cylinder 513 is fixedly connected to the support frame 3. A semi-circular slide groove 517 is provided on the upper front side of the base plate 1. The lower end of the connecting frame 4 is slidably connected to the semi-circular slide groove 517 via a connecting rod.

[0049] The linkage mechanism 6 includes a gear ring 61, a rack 62, and a moving plate 64. The gear ring 61 is fixedly installed in the middle of the rotating table 2, and the rack 62 is fixedly installed on the lower left side of the U-shaped support frame 57 of the third adjustment component. The upper end of the support frame 3 is provided with a T-shaped sliding groove 63, and the moving plate 64 is slidably connected to the T-shaped sliding groove 63. The upper end of the moving plate 64 is fixedly connected to the lower end of the U-shaped support frame 57 of the third adjustment component. The gear ring 61 and the rack 62 are meshed together.

[0050] In this utility model, when the heat dissipation copper pipe moves to the position of the arc-shaped groove 515 on the fixed semicircular plate 51 and the movable semicircular plate 52, the first cylinder 511 works to drive the U-shaped support frame 57 of the second adjustment component to move to the left along the straight guide rod 512, and the second cylinder 513 works to drive the support frame 3 to move to the left until the arc-shaped groove 516 provided on the first fixed plate 53 and the first movable plate 54 contacts the heat dissipation copper pipe, and the arc-shaped groove 516 provided on the second fixed plate 55 and the second movable plate 56 also contacts the heat dissipation copper pipe;

[0051] Then, the rotating platform 2 rotates clockwise, causing the connecting frame 4 to rotate along the semi-circular slide groove 517. At this time, the fixed semi-circular plate 51, the movable semi-circular plate 52, the first fixed plate 53, and the first movable plate 54 rotate together with the rotating platform 2, so that the left end of the heat dissipation copper pipe is always in contact with the arc-shaped groove 515 on the fixed semi-circular plate 51 and the movable semi-circular plate 52, and the right end of the heat dissipation copper pipe is always in contact with the arc-shaped groove 516 on the first fixed plate 53 and the first movable plate 54. During the rotation, the rotating platform 2 rotates, causing the gear ring 61 to move and rotate. The gear ring 61 rotates, causing the rack 62 to move, so that the U-shaped support frame 57 of the third adjustment component moves forward along the T-shaped slide groove 63 with the moving plate 64, so that the rear end of the heat dissipation copper pipe keeps the linear motion. When the rotating platform 2 rotates 180 degrees, the heat dissipation copper pipe is bent into a U-shape.

[0052] When bending a larger diameter heat dissipation copper pipe is required, the servo motors 510 of the first adjustment component, the second adjustment component, and the third adjustment component are activated simultaneously. The servo motors 510 drive the bidirectional lead screw 58 to rotate, causing the fixed semicircular plate 51 and the movable semicircular plate 52 to move synchronously in opposite directions along the guide rod 59 of the first adjustment component. The first fixed plate 53 and the first movable plate 54 move synchronously in opposite directions along the guide rod 59 of the second adjustment component. The second fixed plate 55 and the second movable plate 56 move synchronously in opposite directions along the guide rod 59 of the third adjustment component. This increases the distance between the arc-shaped annular groove 515 and the arc-shaped groove 516, allowing for bending operations on larger diameter heat dissipation copper pipes.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
