[0036] The locking plate 14 is in a strip shape and is located outside the positioning plate 13. One end of the locking plate 14 is hinged to the side of the connecting rod 17 close to the positioning plate 13 through a hinge 21, and the end of the locking plate 14 hinged to the connecting rod 17 can rotate in a plane perpendicular to the end surface of the rotating disk 4.

[0038] When it is necessary to adjust the distance between the pressure block 26 and the annular side wall of the turntable 4, loosen the locking nut 25, rotate the adjusting bolt 24 to move the nut of the adjusting bolt 24 to a suitable position, move the adjusting block 23 to make the adjusting block 23 close to the nut of the adjusting bolt 245, and finally tighten the locking nut 25 so that the locking nut 25 and the nut of the adjusting bolt 24 clamp the two sides of the adjusting block 23 respectively.

[0039] The support roller includes a counterweight base 28 and a non-rotating roller 29, and the non-rotating roller 29 is installed on the counterweight base 28. The support roller is a non-fixed structure, which is placed on the feeding side of the metal pipe according to the needs, and supports the metal pipe during coiling to prevent the metal pipe from sagging during feeding. The lower part of the support roller is a counterweight base 28 to prevent it from tipping over under force, and the upper part is a non-rotating roller 29, which supports the pipe and provides a certain friction force to facilitate better coiling.

[0040] The method of using the practical coiling machine for coiling the above-mentioned metal pipe is as follows:

[0041] 1. Rotate the six outer baffles 6 to a position opposite to the inner baffle 5 and fix them;

[0042] 2. Rotate the turntable 4 to rotate the material head locking mechanism to the lowest position.

[0043] 3. Rotate the locking plate 15 to insert the locking claw 14 into the locking hole 30 of the locking plate 15, place the starting head of the metal pipe in the pressing groove 27 of the pressure head, and support the metal pipe on the anti-rotation roller 29, and move the moving block 16 to the right. The moving block 16 drives the connecting rod 17 to rotate inward, and the connecting rod 17 drives the locking plate 15 to move toward the center of the turntable until the locking claw 14 locks the locking plate 15. Stop moving the moving block 16. At this time, the pressing block 26 presses the starting head of the metal pipe;

[0044] 4. Turn on the motor 8 and start coiling;

[0045] 5. After the coiling is completed, the finished product is packaged through the packaging groove 7. After the packaging is completed, the toggle bar 16 is pushed to the left, and the toggle bar 16 drives the connecting rod 17 to rotate outward. The connecting rod 17 drives the locking plate 15 to move in the direction away from the center of the turntable, and the locking claw 14 slowly disengages from the locking plate 15 until the locking plate 15 is unlocked. At this time, the pressing block 26 is separated from the starting head of the metal pipe, and the locking plate 15 is rotated to make the pressing block 26 away from the annular side wall of the turntable 4, and then the outer baffles 6 are loosened to make the outer baffles 6 be stored on the outer end surface of the turntable 4, and finally the packaged finished coil is removed.
