Going out guide hole, upper bolster 10 is up, and then feeding is to next step, and upper bolster 10 is descending, utilize rush convex closure die 191 and rush convex closure convex
Mould 212 goes out convex closure, goes out through hole through piercing punch 192 and punching concave die 211, and upper bolster 10 is up, then proceedes to feeding extremely
Next step, upper bolster 10 is descending, is punched out first group of C-shaped pole shoe (totally 3), then upper mold through first group of blanking die mold insert 34
Seat 10 is up, and continuation feeding is to next step, and upper bolster 10 is the most descending, is punched out second group of C through second group of blanking die mold insert 33
Shape pole shoe (totally 3), then upper bolster 10 is up, and continuation feeding is to next step, and upper bolster 10 is the most descending, recessed through the 3rd group of blanking
Mould mold insert 29 is punched out the 3rd group of C-shaped pole shoe (totally 2), and then upper bolster 10 continues up, and feeding, to next step, has become waste material
Billot cut off through cutting assembly 30.In blanking process, when upper bolster 10 is descending, contour limited post 26 defines upper bolster 10 times
The distance of row, it is to avoid excessive descending damage equipment and product quality, meanwhile, after upper bolster 10 is up, rectangle floating roof slightly 23 is upwards
By billot jack-up, it is to avoid billot is bonded at and affects it on die block 3 and move, it addition, for the stroke accurately controlling billot, when
When upper bolster 10 is descending, if the vertical shank 161 of step pitch detection guide pin 16 just injects in guide hole, then step pitch detection guide pin 14
One end keep contact in the annular groove 162 of vertical shank 161, if billot moves not in place, vertical shank 161 cannot
Insert guide hole, then vertical shank 161 is by upwards jack-up, and step pitch detection guide pin 14 is forced mobile, the switch being connected with its one end
Close, upper bolster 10 stops descending, it is to avoid dislocation stamping-out and affect product quality.
