Step 3: the distance between arc surface and stainless steel protection pipe of adjustment smooth top wheel (12) guarantee smooth top wheel (12)
Arc surface and stainless steel protection pipe appearance face contact；
Step 4: the height of adjustment smooth top wheel support (14) makes the center of circle of smooth top wheel (12) and the circle of stainless steel protection pipe
The heart is in same horizontal line；
Step 5: the position of adjustment profiling pinch roller support (9) makes the tapered protrusion (10-1) and smooth top wheel of profiling pinch roller (10)
(12) it is oppositely arranged, adjusts the height of profiling pinch roller support (9), make the central point and stainless steel protection pipe of profiling pinch roller (10)
The center of circle is in same horizontal line；
Working stage:
Step 6: starting decelerating motor (16) drives pneumatic scroll chuck (11) rotation, plugs the stainless steel protection pipe not rolled,
Floor push, and turn-on time relay timing are stepped on, high pressure draught flows separately through the first solenoid directional control valve (18-1), the second electricity
Magnetic reversal valve (18-2) and third solenoid directional control valve (18-3), a part of high pressure draught of power gas source are pneumatic scroll chuck
(11) it supplies, another part high pressure draught of power gas source flows through third solenoid directional control valve (18-3) and enters low-pressure gas pipe
Road, high pressure draught through pressure reducing valve (17) be depressurized into low-pressure air current flow through speed governing valve (19) into cylinder (5) air inlet in, cylinder
(5) profiling pinch roller support (9) are pushed and are slided on guide rail (7) with movable slider (8), profiling pinch roller (10) touches stainless steel guarantor
After pillar rolls several seconds, the time relay controls third solenoid directional control valve (18-3) commutation, and high pressure draught enters high pressure gas
Pipeline flows through soft activator (25) and gradually pressurizes, and passes through speed governing valve (19) and enters in the air inlet of cylinder (5), in cylinder (5)
Pressure slowly increase, profiling pinch roller (10) rolls out circular groove on stainless steel protection pipe；
Step 7: unclamping floor push, and the first solenoid directional control valve (18-1) and the second solenoid directional control valve (18-2) commutate, and pneumatic three
Gas discharge in dog chuck (11) and cylinder (5), unloads the stainless steel protection pipe rolled, plugs the stainless steel not rolled and protects
Pillar steps on floor push and turn-on time relay timing again, carries out slot rolling movement to stainless steel protection pipe.
