repeating the steps two to five to complete the cutting of gaps of the multi-section fin groups and the torsion between the adjacent fin groups, enabling the section which is jacked to the left side of the section gear sleeve die and is subjected to cutting torsion to enter the through long sleeve until the whole through long section is subjected to cutting torsion and enters the through long sleeve, and connecting the heat conducting section of the special-shaped fins with the through long sleeve to form a straight pipe section after blanking.
2. The method of manufacturing a twist-and-push device according to claim 1, wherein the push rod is disposed in a push rod sliding groove disposed in a lateral direction, a push rod gear strip disposed along a length direction of the push rod is disposed at a top of the push rod, a push rod motor is disposed above the push rod, a push rod motor gear is disposed at an output end of the push rod motor, and the push rod motor gear is engaged with the push rod gear strip.
3. The method of claim 1, wherein the profile jacket comprises a profile jacket bottom half-round tube and a profile jacket top half-round tube that is configured to open and close.
4. The method for producing the torsion stretching device according to claim 1, wherein the bottom semicircle of the profile jacket is fixedly connected with the top semicircle of the profile jacket through a semicircle fixing pin.
5. The method of claim 1, wherein the cutting motor is mounted on a height lifter and the cutting motor is mounted on the output of the cutting motor.
6. The method for producing the torsion jacking device according to claim 1, wherein a rotary motor is arranged below the profile gear sleeve die, an output end of the rotary motor is connected with a rotary driving gear through a transmission, and the rotary driving gear is meshed with an external gear; the rotating motor can drive the profile gear sleeve die to rotate.
