Expect roller（3）In limiting plate（27）Adjust the position of band in 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 pass through threaded rod（11）Adjust sliding shoe（9）Upper and lower position, so as to adjust high-order corrector roll（6）With low level corrector roll
（7）Between relative altitude, fully eliminate the residual force in band, then pass through high-order corrector roll（6）With low level corrector roll（7）It is right
Band is smoothed；
S3, charging, pass through detection device（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）It starts to work, feed roller（5）It will
Band, which clamps, is sent into diel（2）In, in feed roller（5）When being fed, band is squeezed into again horizontal；
S4, punching and feeding, band enter diel（2）In after, punching die（32）The both sides of band are punched out, shape
At feedhole（28）, material guide mechanism（33）In guide column be inserted into feedhole（28）Middle progress step-by-step movement feeding, make band to
Positive stamping die（13）With reversed stamping die（14）Middle movement；
S5, positive punching press, pass through positive stamping die（13）Punching press is carried out to band from top to bottom, i.e.,：Positive stamping die（13）In
Upper die holder when being separated with lower die holder, pass through cylinder and drive left and right movable block A（19）It is displaced outwardly, to make the support of left and right sides
Plate（18）By positive cavity plate（24）It props up, positive punch-pin（23）Fall to groove A（21）In, band is from positive punch-pin（23）Just
To cavity plate（24）Between pass through, cylinder drives left and right movable block A again（19）Inwards with movement, make the support 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 die holder to
Lower punching press, to which strike is in positive cavity plate（24）On, form protrusion A（25）, realize the positive punching press to band；
S6, reversed punching press, reversed stamping die（14）Upper die holder it is motionless, reversed stamping die（13）In left and right movable block C（37）
In sliding slot D（36）Middle movement, to push reversed protrusion（35）It moves up, punching press is carried out to band from the bottom up, formed convex
Play B（26）, at this point, die pad（15）It is pressed into liftout groove, reversed protrusion（35）When downward return, die pad（15）Bullet
It rises, die pad（15）Band is jacked up, the movement of band is convenient for.
7. the moulding process of screen work band in nuclear power generation device according to claim 6, it is characterised in that：The punching press
Mold（2）In all positive punching presses all carry out together, diel（2）In all reversed punching presses be all to carry out together
