分析刀片表面淬火变形的原因和规律,利用热应力原理,在刀片刃口的对边预先连续加热,冷却,获得预变形,然后再对刀片刃口进行连续加热,淬火,可以有效地解决刀片表面淬火“镰刀状”变形问题。文中还对刀片预变形的方法、大小,部位进行了研究,介绍了刀片预变形中频淬火生产工艺和几个注意的问题。 Analysis of the reasons and rules of the blade surface hardening deformation, the use of thermal stress principle, the edge of the blade edge pre-continuous heating, cooling, pre-deformation, and then the blade edge continuous heating, quenching, can effectively solve the blade surface Quenched “sickle-shaped” deformation problems. The method, the size and the location of the blade pre-deformation are also studied in this paper. The production process of the blade pre-deformation IF quenching and several problems to be noticed are introduced.
