1. The adjustment worker must undergo more than three months of follow-up learning and more than three months of coach operation, proficiently grasp the functions of various switches on the control console, be able to proficiently measure the circumference of the pipe, and cooperate with the internal welder to control the circumference of the pipe. After passing the exam, they are allowed to work on the job.

2. By using the method of cold coil forming and using the SM1220 pipe making unit, the equipment should be in good condition.

3. Before starting the operation, it is necessary to be familiar with the specifications and process requirements of the currently produced pipes.

4. Pay attention to the compliance of the position and status of the forming wheel, the angle of the feeding table, and the width of the plate.

5. Measure the circumference of the pipe at least once per screw circumference and keep records.

6. When the adjustment of the pipe circumference requires jogging and feeding into the corner, the internal welder should be informed to cooperate.

7. Draw at least one external welding alignment line for each screw circumference.

8. Before starting the machine, coordinate with each position to prepare and shout "Start" and "Start" loudly.

9. Pay attention to the working conditions of each position of the host during operation. When there is a situation where the machine is stopped, shout "stop -" loudly.

10. Adjust to ensure the coordination of work among various positions and the stability of pipe forming as the criterion.

11. Find the delivery line and deliver the sheet along the delivery line to the front of roller 1.

12. Adjust the angle of rollers 1, 2, and 3. (Note: The angle of roller 2 is less than that of roller 1 and roller 3, and the angle of roller 2 is calculated based on the inner diameter of the pipe).

13. Adjust the degree of deviation between rollers 1 and 3 and the plane, while also adjusting the surface roughness of rollers 1 and 3. (Note: The deviation degree can be calculated in computer graphics, and the roller surface marking is the same as the corresponding outer diameter radian marking of the inner support plate when the second roller is pressed.).

14. Adjust the center height of the inner support plate, the angle of the wheels on the inner support plate, and the corresponding wheel markings of the inner support plate. (Note: Adjust the center point of the Peugeot inner support plate of the wheel to the center point of the inner diameter of the pipe, and the Peugeot arc of the wheel is equal to the inner diameter arc of the pipe).

15. Adjust the appearance and angle of the solder joint roller (i.e. the supporting roller), and place the solder joint roller at the center point (note: when placing, the center point of the solder joint roller should correspond to the No. 2 roller).

16. Adjust the spacing under roller 2 to form the corresponding pipe diameter curvature. (Note: The formed arc is generally smaller than the actual arc diameter by about 1-3mm).

17. After the pipe head comes out, follow the same three-roll adjustment method. (Conveyor roller on rear axle)
