Dynamic blank latter end 6 retracts to the right 600mm, then controlling makes front clamp cylinder 204 and rear clamping cylinder 207 be reset to original state；
10) control u-turn lifting cylinder 404 acts, until its piston rod stops dynamic to range, u-turn lifting cylinder 404 is reached
Make, control u-turn clamping cylinder 402 acts, until its piston rod is to range is reached, u-turn 402 stopping of clamping cylinder movement is simultaneously
The clamping to blank latter end 6 is completed in pressure maintaining；
11) control u-turn lifting cylinder 404 is reset to original state, and control u-turn motor 407 acts, until speed reducer 406 is defeated
Placing half rotation (180 °), i.e. drive 6 head and the tail of blank latter end are turned, u-turn 407 stopping of motor movement；
12) control u-turn lifting cylinder 404 acts, until its piston rod stops dynamic to range, u-turn lifting cylinder 404 is reached
Make, control u-turn clamping cylinder 402 is reset to original state, unclamps the clamping of base latter end hair 6, then control u-turn lifting cylinder
404 are reset to original state, so far, complete the head and the tail overturning to blank latter end 6；
13) step 6 is repeated, then controls former and later two and is sent into the movement of cylinder 202, so that its piston rod is sent into 600mm to the left, thus band
Dynamic blank latter end 6 is sent into 600mm to the left, then controlling makes front clamp cylinder 204 and rear clamping cylinder 207 be reset to original state；
14) step 3-5 is repeated.
So far the fixed length for just completing the complete long blank 5 of a piston ring carrier is sawed-off, the long blank 5 of next piston ring carrier
Sawed-off processing repeat step 1-14.
