DEVICE FOR MAKING SLOTS ON CONTINUOUSLY MOVING SECTION Russian patent published in 2005 - IPC

FIELD: mechanical engineering; plastic metal working.

SUBSTANCE: proposed device contains lower drive shaft installed in two fixed housing on which punch with pack of cutting disks is installed, two movable housing in which two adjusting nuts with screws are mounted, and upper shaft with die in form of pack of disk. Movable housing are made for displacement in vertical plane along two columns installed in fixed housing. Disks of die differ in diameter, with alternation of larger diameter disk and smaller diameter disk. Outer surface of blades of punch cutting disk has cylindrical and conical sectional of corresponding width and tilting of generatrix of cylindrical section at angle to axis of symmetry of cutting disk. Disks with cylindrical outer surface are fitted between cutting disks. Diameter of said disks is less than diameter of cutting disks. Disks of die of smaller diameter are arranged over cutting disks, and disks of die of larger diameter are arranged over disks of punches with cylindrical outer surface.

EFFECT: enlarged operating capabilities owing to changing of shape and size of slots.
