MEASURING KNIFE WEAR-OUT DEGREE AND KNIFE EXCHANGING DEVICE OF ROLLING ROTATABLE CUTTER

摘要

The present invention relates to a knife wear measuring and knife changing device of a rotary cutting machine that cuts the front end and the end of the strip at right angles to the longitudinal direction in the process just before finishing rolling in a hot rolling mill. A multi-stage knife holder, which is mounted on a support formed in the upper end of the rolling mill; A magnetic wrench having a wrench socket formed at a tip thereof and having a magnetic wrench capable of forward and reverse rotation so as to simultaneously remove and fix the knife fixing bolt that fixes the knife; A drawer unit having a bead-shaped knife changer rod inserted into a knife changer groove formed in the knife so as to replace the knife; The upper and lower drums are fixed to the upper surface of the take-out unit so as to be kept in a replaceable state by shanghai-dong, and the upper surface is horizontally constructed to connect with the rotating shaft engaged with the rack gear of the Shanghai-dong guide. A moving unit installed; A measuring part installed in front of the magnetic wrench and having a contactor to be in contact with the knife blade of the knife along a rotating screw to measure a wear value and a shape of the knife; And a detection device unit for recording, reading and controlling the value measured from the measurement unit.;This invention has the advantage of improving the efficiency of the replacement operation of the new knife as well as ensuring the safety of the worker, and improves the productivity of the rolling process.
