SHEET BLANK WORKING APPARATUS Russian patent published in 2007 - IPC B21C25/00 B21J5/00 C22F1/18 

FIELD: plastic working of materials, namely apparatuses for strengthening material at working process.

SUBSTANCE: apparatus for working sheet blanks by equal-duct angular pressing includes housing in which roll with П-shaped groove is mounted; annular sector insert joined with roll groove and secured to block. Said insert has contact surface arranged eccentrically relative to contact surface of roll and it forms stationary wall of working duct for receiving blank. Said block is joined with housing by means of wedge clamp and it is mounted in axle with possibility of rotation. Stop is mounted in recess of housing for forming lower wall of outlet duct. Apparatus may perform translation motion and its housing is rigidly secured to strut coupled with frame. Apparatus includes platform for receiving blank after pressing it out in motion direction of apparatus. Roll having annular bandages along its ends is mounted with possibility of rotation. Roll, П-shaped groove, annular sector insert and block have such geometry sizes that provide pressing of blank. Blank is pressed out in direction opposite relative to motion direction of apparatus. In order to enhance efficiency of working roll is in the form of vibrating roll.

EFFECT: possibility for working large-size sheet blanks, improved manufacturing effectiveness and efficiency of working of sheet blanks.
