On the basis of the above embodiment, further, a second U-shaped bracket 34 is provided on a carrying surface opposite to the flare unit 3 on the side of the station where the radiating pipe 4 is placed.
In this embodiment, the number of the second U-shaped brackets 34 can be determined according to the number of U-shaped pipes in the heat dissipation pipe 4, and the second U-shaped brackets 34 are conventional structures and will not be described herein. The second U-shaped bracket 34 is used for supporting the U-shaped pipe in the radiating pipe 4, so as to position the radiating pipe 4 in the Y-direction during the flaring process.
In addition to the above embodiment, as in the expansion unit 2, a bracket provided on the work table 1 may be used, and a clamp for limiting the degree of freedom of the heat dissipation pipe 4 in the Z-axis direction is supported on the bracket located above the flaring unit 3, and the structure of the clamp is not particularly limited as long as the clamp for the heat dissipation pipe 4 can be satisfied. Of course, it is easily conceivable that the heat pipe 4 can be clamped in the Z-axis direction in other manners, such as a robot clamping fixture, and in this case, a bracket for supporting the fixture does not need to be disposed on the work table 1.
On the basis of the above embodiment, a conveyor belt (not shown) is further disposed at the position of the radiating pipe 4 corresponding to the pipe expanding unit 2 and the flaring unit 3, and the conveyor belt can be lifted above the bearing surface and lowered to be flush with or below the bearing surface.
In this embodiment, the heat dissipation pipe 4 to be expanded and flared is conveyed to the corresponding station by the conveyor belt, and when expanded and flared, the conveyor belt is lowered to be flush with or below the bearing surface, that is, the heat dissipation pipe is supported by the bearing surface of the worktable 1, which has the advantage of high automation degree.
To sum up, the utility model relates to an even expand tube device of horizontal atmospheric pressure can overcome the great grade shortcoming of damage cooling tube, shrink and overall dimension that current mechanical type expand tube exists, but also has the nozzle of convenience and extracts from the cooling tube, advantage such as degree of automation height.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
