黄石锻压机床厂设计试制了Q42—315型棒料剪断机,在该设备上采用了东德ERFURT公司同类产品的一种新颖的压料机构,经过实践证明是成功的,现已投入生产。这种压料机构与国内外同类产品相比,结构简单,性能良好。压料机构的作用是当棒料被剪切时能抵抗由剪切力引起的翻转力矩,保持棒料不翻转。这种压料机构的结构如图示,压料活塞平常总是挂在刀架伸出部分的挂销上,因而只有当刀
Huangshi forging machine tool plant designed trial production of Q42-315 bar cutting machine, the device used in East Germany ERFURT similar products a new pressure-feeding mechanism, proved to be successful, has been put into production. Compared with the similar products at home and abroad, this pressure-feeding mechanism has the advantages of simple structure and good performance. The function of the material pressing mechanism is to resist the overturning moment caused by the shearing force when the bar material is sheared and to keep the bar material not to be turned over. The structure of the material pressing mechanism is shown in the figure, the material pressing piston is always hung on the hanging part of the extended part of the knife holder, and therefore only when the knife
