Abstract

The invention discloses a heating quenching inductor with different heat distributions, and the heating quenching inductor is used for carrying out quenching treatment on a web type gear which is uniformly provided with weight-reducing holes. The heating quenching inductor comprises a ring-shaped effective heating ring and an insulating supporting frame, wherein the outer side wall of the ring-shaped effective heating ring is provided with a plurality of quenching water tubes; the inner side wall of the ring-shaped effective heating ring is uniformly distributed with a plurality of a water outlet fine holes; the upper end of the insulating supporting frame is provided with a cavity which is matched with the web type gear; the outer side wall of the ring-shaped effective heating ring is uniformly embedded with a plurality of magnetizers; and the magnetizers and the weight-reducing holes are arranged in a staggered mode. According to the heating quenching inductor, heat, generated by a peripheral part, close to the weight-reducing holes, of the gear is lower than heat generated by the peripheral part, far from the weight-reducing holes, of the gear, so that thermal deformation caused by induction heating and surface quenching is greatly reduced, and a follow-up milling process is omitted, and therefore, the gear production efficiency is improved and the gear manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of quenching inductors, in particular to a heating and quenching inductor with different heat distributions. Background technique [0002] Induction heating surface hardening is a heat treatment process that uses electromagnetic induction to generate eddy currents in the workpiece to heat the workpiece and then rapidly cools it. The workpiece after induction heating surface hardening has the advantages of high surface hardness, high fatigue strength and good wear resistance, and Compared with other surface heat treatment processes, induction hardening has the advantages of fast heating speed, high thermal efficiency, small workpiece deformation, and less surface oxidation and decarburization, so it is especially suitable for workpieces that are subjected to alternating loads such as torsion and bending, and impact loads. (such as gears). [0003] Among them, the quenching sensor is the terminal equipment fo...
