S1, guide, first place in the base, by guide rack unprocessed band（3）Import correction machine（1）In, by leading
Material roller（3）In limiting plate（27）Adjustment band is in the position of left and right directions；
S2, smoothing, import correction machine（1）In band pass through high-order corrector roll（6）With low level corrector roll（7）, rotate adjustment disk
（10）And by threaded rod（11）Adjustment sliding shoe（9）Upper-lower position, so as to adjust high-order corrector roll（6）With low level corrector roll
（7）Between relative altitude, the residual force in band is fully eliminated, then by high-order corrector roll（6）With low level corrector roll（7）It is right
Band is smoothed；
S3, charging, by detection means（4）In height sensors（12）Measure band and height sensors（12）Between height
Degree, when band and height sensors（12）Height be less than 200 ~ 300mm when, feed roller（5）Start working, feed roller（5）Will
Band clamps feeding stamping mold（2）In, in feed roller（5）When being fed, band is squeezed into again horizontal；
S4, punching and feeding, band enter punching press grinding tool（2）In after, punching die（32）Both sides to band are punched out, shape
Into feedhole（28）, material guide mechanism（33）In guide column insertion feedhole（28）In carry out step-by-step movement feeding, make band to
Positive stamping die（13）With reverse stamping die（14）Middle movement；
S5, positive punching press, by positive stamping die（13）Punching press is carried out to band from top to bottom, i.e.,：Positive stamping die（13）In
Upper bolster when being separated with die shoe, movable block A in left and right is driven by cylinder（19）Moved outside phase, so that the support of left and right sides
Plate（18）By positive cavity plate（24）Prop up, positive punch-pin（24）Fall to groove A（21）In, band is from positive punch-pin（24）Just
To cavity plate（23）Between pass through, cylinder drives left and right movable block A again（19）Inwards with movement, make the supporting plate of left and right sides（18）Point
Groove A is not fallen to（21）With groove B（22）In, realize the compression to band, positive stamping die（13）In upper bolster to
Lower punching press, so as to hit in positive cavity plate（23）On, form projection A（25）, realize the positive punching press to band；
S6, reverse punching press, reverse stamping die（14）Upper bolster it is motionless, reverse stamping die（13）In left and right movable block C（37）
In chute D（36）Middle movement, so as to promote reverse projection（35）Move up, carry out punching press to band from the bottom up, formed convex
Play B（26）, now, die pad（15）It is pressed into liftout groove, it is reversely raised（35）During downward return, die pad（15）Bullet
Rise, die pad（15）By band jack-up, it is easy to the movement of band.
7. in nuclear power generation device according to claim 6 screen work band moulding process, it is characterised in that：Described punching press
Mould（2）In all positive punching press all carry out together, stamping mold（2）In all reverse punching press be all to carry out together
