Abstract

The invention discloses a special quenching inductor for a rotary support rail. The special quenching inductor comprises a pair of conductive connection plates, wherein one ends of the pair of conductive connection plates are connected with an annular effective heating ring, the pair of conductive connection plates forms a closed current circuit with the effective heating ring, cooling liquid channels are arranged in the pair of conductive connection plates and the effective heating ring, the effective heating ring and the pair of conductive connection plates form a circulating cooling liquid channel, and a clamped magnetizer is arranged on the effective heating ring; an installation-fixation plate is arranged above the effective heating ring, and one side of the installation-fixation plate is fixed on the pair of conductive connection plates through a pair of fixed support seats; and a first annular water sprayer is arranged below the effective heating ring, the installation-fixation plate is connected with the first water sprayer, the effective heating ring and the first water sprayer are correspondingly arranged in a manner of vertical concentricity, and water spray holes are distributed in an end surface corresponding to a workpiece, of the first water sprayer. The device increases the efficiency by 6-10 times and saves energy compared with an existing local scanning manner.

Description

technical field [0001] The invention belongs to the field of quenching inductors, in particular to a special quenching inductor for slewing support rails. Background technique [0002] The slewing support is an important component widely used in excavators, cranes, and mining machinery. Its circular track is a key indicator of the quality of the entire component. Due to long-term friction and rotation with balls, the hardness of the track must be increased to extend the rotation Support life. Induction hardening is an economical, reliable and environmentally friendly way to increase the hardness of the track surface. At present, the local scanning method is generally adopted for the induction hardening of various large, medium and small slewing bearings in China (that is, after the gap between the quenching sensor and the workpiece, the angle is adjusted, the positioning is not fixed, the workpiece is rotated, and the induction hardening of the track is completed through co...
