Abstract

Изобретение относитс к обработке металлов давлением и может быть использовано дл разрезани непрерывно движущейс полосы, например гофрированного металла. Цель изобретени - улучшение качества издели за счет увеличени точности реза по длине. При резке гофрированных полос требуетс соблюдение высокой точности размеров, которое достигаетс кинематической св зью механизма резки и привода механизма формообразовани -механизма гофрировани полосы. Эта св зь осуществл етс посредством захватного устройства с зажимными губками (ЗГ) 16, установленного на той же каретке 4, что и механизм резки, и гибкой передачи, одна из звездочек 20 которой находитс в зацеплении с выходной шестерней привода механизма гофрировани 21. ЗГ 16 в заданный момент зажимают гибкий элемент, а именно цепь 25 передачи, замыка таким образом кинематическую цепь. При этом обеспечиваетс движение каретки 4 с механизмом резки со скоростью, равной скорости разрезаемой полосы. 1 з.п. ф-лы, 3 ил.The invention relates to the processing of metals by pressure and can be used to cut a continuously moving strip, e.g. a corrugated metal. The purpose of the invention is to improve the quality of the product by increasing the accuracy of the cut along the length. When cutting corrugated strips, compliance with high dimensional accuracy is required, which is achieved by the kinematic connection of the cutting mechanism and the drive of the shaping mechanism — a strip corrugation mechanism. This communication is carried out by means of a gripping jaw (16) gripping device mounted on the same carriage 4 as the cutting mechanism and a flexible transmission, one of the sprockets 20 of which is in engagement with the output gear drive of the corrugation mechanism 21. SR 16 at a given time clamp the flexible element, namely the chain 25 of the transmission, the closure thus kinematic chain. This ensures the movement of the carriage 4 with the cutting mechanism at a speed equal to the speed of the strip being cut. 1 hp f-ly, 3 ill.
