Abstract
Изобретение относитс к обработке металлов давлением, в частности К устройствам продольной резки листового проката на дисковых ножницах . При этом получаемые заготовки примеК ютс дл производства гибких металлических рукавов. Цель изобретени - повышение качества металлических рукаэов. Дисковые ножницы выполнены с ножами монотонно возрастающего диаметра на одном валу и монотонно убьшающего - на другом так, что сумма диаметров на каждом из участков вл етс величиной посто нной . Кроме того, режущие кромки ножей спрофилированы по дугам окруж- стей радиусом, равным 0,1-0,25 длииы участка ножа посто нного диаметра. Рулон закрепл ют на оправке разматы- вател 1, пропускают лист через ножи 3, концы полученных лент закрепл ют в приемные барабаны 4. Последние привод тс во вращение от привода 6 через передач у 5. 1 з,п. ф-льг, 6 .ил. а $ (ЛThe invention relates to the processing of metals by pressure, in particular to devices for longitudinal cutting of sheet metal on disc shears. The resulting blanks are used for the production of flexible metal hoses. The purpose of the invention is to improve the quality of metal sleeves. Disk shears are made with knives of monotonously increasing diameter on one shaft and monotonously killing - on the other, so that the sum of the diameters on each of the sections is constant. In addition, the cutting edges of the knives are shaped along arcs of a circle with a radius of 0.1-0.25 in the length of the knife section of constant diameter. The roll is fixed on the mandrel of the rammer 1, the sheet is passed through the knives 3, the ends of the tapes obtained are fixed in the receiving drums 4. The latter are rotated by the drive 6 through the gears 5. 5. C, p. F-lg, 6. a $ (L
