The main applications of copper tube busbar include high-voltage power distribution, substations, power plants and power connections of large industrial equipment. Compared with traditional copper wires, copper tube busbar has the advantages of good conductivity, strong heat dissipation capacity and high mechanical strength.

[0003] For example, the patent with the authorization announcement number CN221473128U and the authorization announcement date August 6, 2024, and the name "A fully insulated copper tube busbar bending machine with high adaptability", includes a main body and a limit assembly, and the limit assembly is arranged on the outside of the main body, and the limit assembly includes an upper mounting seat, a pneumatic rod, a mounting block, a clamping groove, a clamping block, an upper clamping block, a lower mounting seat, a lower clamping block, a fixed seat, a threaded rotating rod, an auxiliary turning handle, a movable rotating shaft and a model roller, and a pneumatic rod is arranged in the middle of the lower end of the upper mounting seat, and a mounting block is arranged at the front end of the pneumatic rod, and a clamping groove is arranged inside the mounting block, and a clamping block is connected inside the clamping groove.

Specifically, before the copper tube busbar 7 is bent, the copper tube busbar 7 is first passed between the two arc plates 54 in the rotating cylinder 50. At this time, the second spring 55 can pull the mounting rod 53 and make the mounting rod 53 drive the arc plate 54 to approach and fit the outside of the copper tube busbar 7. At this time, the driving gear 52 is driven to rotate by the motor 51, so that the driving gear 52 drives the rotating cylinder 50 to rotate through the gear teeth on the outside of the rotating cylinder 50.

[0059] In another embodiment provided by the present invention, a heat dissipation portion 740 is provided on the outer side of the protective layer 74;

[0060] A specific implementation is as follows: the cross-section of the protective layer 74 is polygonal, such as a hexagon, and a heat dissipation portion 740 is provided on the side of the polygon. The heat dissipation portion 740 is an arc-shaped protrusion. The heat dissipation portion 740 increases the area between it and the insulating sheath 75 through the arc surface, so that the heat dissipation portion 740 can dissipate the heat transferred to the copper tube 70.

[0061] Working principle: Place the copper tube 70, first manually pass the copper tube 70 through the rotating cylinder 50, so that the copper tube 70 passes between the two arc plates 54 in the rotating cylinder 50, at this time, the second spring 55 can pull the installation rod 53 and make the installation rod 53 drive the arc plate 54 to approach and fit the outside of the copper tube 70, in addition, the copper tube 70 will pass through the feed hole 30, so that the first spring 33 squeezes the sliding rod 32, so that the sliding rod 32 drives the guide plate 31 to move toward the axis of the feed hole 30, so that the first spring 33 squeezes the sliding rod 32 to drive the guide plate 31 to clamp and position the copper tube 70, and at the same time the second spring 55 pulls the installation rod 53 to drive the arc plate 54 to clamp and position the copper tube 70, and then continue to rotate The copper tube 70 is transported in the cylinder 50 and the feed hole 30, so that the copper tube 70 is between the fixed bending wheel 40 and the movable bending wheel 42, and the bending position of the copper tube 70 is between the fixed bending wheel 40 and the movable bending wheel 42. After the position of the copper tube 70 is determined, the guide plate 31 and the arc plate 54 can clamp and limit the copper tube 70; the arc-shaped guide plate 31 facilitates the combination of multiple guide plates 31 into a circle to guide and limit the copper tube 70, and when the copper tube 70 passes through the circle formed between the guide plates 31, the axes of the arc structures of each guide plate 31 coincide, and at the same time, the inclined surface on the guide plate 31 facilitates the copper tube 70 to pass through the circle formed between the guide plates 31 and enter between the fixed bending wheel 40 and the movable bending wheel 42;
