众所周知,细长工件的高频淬火,防止变形是一个突出的难题。在立式淬火机床上利用托辊(导轮)和可伸缩的上顶尖,可以减少细长工件淬火时的变形。但是对于工件长度与直径之比大于40,而且要求高硬度的拉矫机工作辊,常规的工装措施难以达到技术要求。为此,设计了高频淬火机床专用拉 As we all know, slender workpiece induction hardening, to prevent deformation is a prominent problem. In the vertical quenching machine using roller (guide wheel) and retractable on the top, you can reduce the deformation of the elongated workpiece quenching. But for the workpiece length to diameter ratio greater than 40, but also requires high hardness straightening machine working roll, conventional tooling measures difficult to meet the technical requirements. To this end, designed a special high-frequency quenching machine pull
