[0033] Working principle: When in use, the device can be first transported to a designated position and powered on. Then, the micro-channel aluminum flat tube to be processed is passed through the side of the operating table 10 close to the straightening side plate 9 and inserted into the middle position at the mutually approaching ends of the two groups of straightening side plates 9. Then, rotate the first threaded rod 2 to drive the inner threaded sleeve block 1 to move up or down on its surface. Through the movement of the inner threaded sleeve block 1, the articulated movement of the two groups of first hinge rods 11 can be realized, so that the first hinge rod 11 can drive the sliding plate 4 to move or move away inside the through groove 5. At this time, through the movement or movement away of the sliding plate 4, the movement of the two groups of straightening side plates 9 can be realized to approach or move away. Through the movement of the straightening side plates 9 to approach or move away, the straightening and limiting operations of micro-channel aluminum flat tubes of different sizes can be realized.

[0034] During fixed-length cutting, the operator can directly rotate the second threaded rod 18 to drive the inner threaded sleeve block 2 and 17 to move up on its outside. Then, the inner threaded sleeve block 2 and 17 drive the second hinge rod 16 to perform articulated movement, so that the second hinge rod 16 can push the fixed-length plate 13 and the components above it to move. Then, the fixed-length plate 13 can drive the limiting rod 15 to move inside the base 1. At this time, through the movement away of the fixed-length plate 13, the fixed-length cutting operation of the micro-channel aluminum flat tube can be realized. Later, it is not necessary for the operator to rely on his own experience and other measuring mechanisms to realize the fixed-length cutting of the pipeline, improving the convenience and practicality of subsequent cutting.
[0035] Finally, when the pipeline is being straightened and pushed, it can gradually approach the fixed-length plate 13. Before approaching, the pipeline can first push the push plate 22 to drive the telescopic rod 23 to perform a compression operation, and then the contact of the two groups of metal contact pieces 14 is realized. Through the contact of the metal contact pieces 14, a closed circuit is formed. Then, the second electric push rod 20 is opened to push the cutting main body 21 down to realize the cutting function of the pipeline.
