B690液压牛头刨床没有自动抬刀装置,这样,一方面在刀台自重的作用下,刀尖与已加工面产生摩擦磨损,降低刀具耐用度和拉伤已加工表面;另一方面不能满足某些产品的工艺技术要求。如轴承行业的工具生产中,磨钢球用的锉盘需要保持锋利和齿距相等的60°齿形。因此,在刨削时要求滑枕工作行程结束时,刀具自动抬刀,以消除刀具与齿形的摩擦。本文介绍的液压抬刀装置,已在实际生产中使用数年,其特点是结构紧凑、动作灵活、保持了原机床设计的各种运动精度。
B690 hydraulic shaper does not automatically lift the knife device, so that on the one hand in the role of the knife under dead weight, the tip and the machined surface friction and wear, reduce the tool durability and strain the surface has been machined; the other hand can not meet certain Technical requirements of the product. In the production of tools for the bearing industry, for example, the rasp disk for grinding balls needs to have a sharp 60 ° tooth profile with an equal pitch. Therefore, when planing requires the ram to work stroke end, the tool automatically lift the knife to eliminate the friction between the tool and the tooth shape. This article describes the hydraulic lift knife device, has been used in actual production for several years, which is characterized by compact structure, flexible action, maintaining the original design of the original machine a variety of motion accuracy.
