ADJUSTMENT OF POSITION OF TRIMMING KNIVES Russian patent published in 2024 - IPC B23D19/04 

FIELD: machine building.

SUBSTANCE: group of inventions relates to rolling lines, in particular to devices for trimming. Proposed device comprises top and bottom blades. Upper blade comprises main annular surface with diameter D1 and thickness Tl, is installed on upper shaft. Bottom blade comprises main circular surface with diameter D2 and thickness T2 and fitted on bottom shaft. Said upper and lower knives are shifted vertically to form an overlap to set the cut of said metal sheet. Upper shaft and/or lower shaft are made with possibility of vertical movement. Device contains the first distance sensor designed to measure the distance along the vertical to the upper end of the said upper knife. Device also comprises a second distance sensor for measuring the vertical distance to the lower end of said lower blade, and a computing device configured to calculate said overlap.

EFFECT: accurate measurement of overlap and gap.
