Description

Technical Field

[0002] A heat pipe is a component with heat transfer properties. It can quickly transfer the heat of a heating object to the outside of the heat source through the rapid transfer of heat conduction away from the cooling medium. It has excellent thermal conductivity and is widely used in aerospace, military and other industries. Usually, the finished heat pipe has conical outer ends on both sides, and is bent by clamping tooling and bending equipment during the bending process.

[0003] According to the "A Heat Pipe Bending Machine" with Chinese Patent Publication No. CN218692835U, it mainly describes that by setting a heightening plate, an R-rubber mold heightening plate and a rotating heightening plate, the spatial distance between the heat pipe and the bottom plate is effectively increased, which is convenient for bending products with higher step differences, and solves the limitation that it was previously only applicable to horizontal pipe bending. A thermal switch tilt angle positioning block is set, and the tilt angle swing operation is simple, which is convenient for positioning products with relatively large tilt angles for bending. A bending angle positioning block is set for the limiting operation of the rotating plate, and cylinder one and cylinder two are used for easy clamping. A length positioning component is used to meet the bending requirements of heat pipes of different lengths. The utility model is a flexibly heightened bending machine, which solves the problem of 3D heat pipe bending and forming. In this process, the bending radius is limited by the size and diameter of the heat pipe. When different heat pipes need to be bent, adjustment is more troublesome.

[0004] Therefore, a heat pipe bending machine is proposed to solve the problem that the bending radius is limited by the size and diameter of the heat pipe during the process, and the adjustment is troublesome when different heat pipes need to be bent. Utility Model Content

[0007] As a preferred technical solution of the utility model, a first screw is rotatably connected in the first groove, and the first screw is threadedly connected to a contact block.

The rotating disk 7 and the rotating plate 8 rotate, thereby driving the heat pipe to bend. A semi-circular disk is integrally formed on one side of the auxiliary plate 6 by casting. The semi-circular disk can be replaced when disassembled and can also be used as a bending radius of the heat pipe. The rotating rod 5 is located on the upper side of the support plate 4 and is fixedly connected to the rotating disk 7. One side of the rotating disk 7 is fixedly connected to the rotating plate 8. A first groove is opened in the rotating plate 8 and a contact block 10 is arranged in the first groove.

[0018] The contact block 10 is threadedly connected to the first screw rod 9, and the first screw rod 9 is rotatably connected to the first groove. By setting the first screw rod 9 and the contact block 10, the positions of the support rod 11 and the pressure plate 12 can be adjusted to adapt to the diameter of the hot-bent pipe.
