Abstract

Изобретение относитс к обработке металлов давлением, а именно к резке проката. Цель изобретени - упрощение конструкции. Рама 2 перемещаетс до соприкосновени ножа 4 с прутком, лежащим на ноже 8. При дальнейшем перемещении рамы 2 прижим 3 перемещаетс по наклонным поверхност м рамы 2 и ножа 4 до соприкосновени его с прокатом. При этом нож 4 остаетс неподвижным относительно проката, рама 2 перемещаетс вниз, а прижим 3 - вверх и в сторону плоскости реза Прокат зажимаетс прижимом 3. Прижим 7 под действием проката на нож 8 по наклонным поверхност м ножа 8 и корпуса 1 перемещаетс до соприкосновени с прокатом Дальнейшее перемещение рамы 2 приводит к отрезке заготовки, при этом прокат и отрезаема заготовка зажаты с усилием, пропорциональным усилию резки. 5 ил А-АThe invention relates to the processing of metals by pressure, in particular to the cutting of rolled products. The purpose of the invention is to simplify the design. The frame 2 moves until the blade 4 contacts with the bar lying on the knife 8. With further movement of the frame 2, the clamp 3 moves along the inclined surfaces of the frame 2 and the blade 4 until it contacts the rolled metal. In this case, the knife 4 remains stationary relative to the rolling, the frame 2 moves downwards, and the presser 3 moves up and toward the cutting plane. The rolling is clamped by the presser 3. Under the action of the rolling on the knife 8, the clamp 7 moves along the inclined surfaces of the knife 8 and the body rental Further movement of the frame 2 leads to a piece of the workpiece, while rolling and cutting the workpiece are clamped with a force proportional to the cutting force. 5 il A-A
