Abstract

A U-shaped groove surface quenching inductor comprises an induction heating part, a plurality of cooling parts and a supporting rack, the induction heating part and the plurality of cooling parts are fixedly arranged on the supporting rack, the induction heating part is formed by a busbar, an effective loop and a group of magnetizers, the effective loop is a variable cross section structure with the cross section gradually reducing along the length direction, and a cooling hole is arranged in the effective loop; and the group of magnetizers with U-shaped cross section is jointed to the effective loop, and the dimension of the U-shaped cavity of every magnetizer adapts to the dimension of the corresponding effective loop cross section. The variable cross section effective loop is adopted, and the magnetizers change with the effective ring and the part structure, so the U-shaped groove surface quenching inductor has the advantages of high quenching efficiency, uniform hardness distribution, simple structure and low production cost.

Description

technical field [0001] The invention relates to the field of quenching inductors, in particular to a U-shaped groove surface quenching inductor. Background technique [0002] In order to increase the mechanical strength and wear resistance of auto parts, quenching is usually used. According to the quenching part, it is divided into overall quenching and surface quenching. To improve surface properties, surface quenching is generally used. [0003] For large-diameter U-shaped groove surface quenching, the inductor is generally designed and manufactured according to the inner hole quenching inductor; for small-diameter U-shaped groove surface quenching, there are difficulties, such as figure 1 As shown, the mark 1 in the figure is the required quenching part, that is, the bottom of the U-shaped groove: the inductor cannot be designed and manufactured according to the inner hole quenching inductor, and the heating efficiency is extremely low, and it cannot even be heated. The...
