Description

Slewing bearing raceway heat treatment inductor

Technical Field

The utility model belongs to the technical field of induction heating, concretely relates to slewing bearing raceway heat treatment inductor.

Background

At present, a known slewing bearing raceway heat treatment inductor is generally processed into a semi-circular arc shape matched with a raceway or is profiled with the raceway, when the inductor is used for processing multi-raceway products such as double-row balls, the processing of the products cannot be completed through one-time heating, and the difficulty of heat treatment quality process control is brought by multiple times of heating, for example: the second heating can affect the hardness of the first heating, and the uniformity of each heating is difficult to control.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a slewing bearing raceway heat treatment inductor just accomplishes raceway heat treatment's inductor through one shot forming, has improved the efficiency of part production, can the energy saving, can avoid advantage such as the influence of repetitious heating to process control again.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model relates to a slewing bearing raceway heat treatment inductor, the mounting panel, first heating induction coil, second heating induction coil, third heating induction coil, fourth heating induction coil, the magnetizer, the reinforcing plate, the limbers, induction coil connecting device, turning optimizing apparatus, the mounting hole, the electric current gets into through the last raceway induction coil through mounting panel one utmost point, make magnetic field gathering improve heating efficiency in the position of installing the magnetizer, pass through turning optimizing apparatus at the corner and reduce corner magnetic field density, it is overheated to make the turning be difficult to produce, raceway induction coil under the rethread, realize the heating of raceway down simultaneously, finally flow back to realization induction heating from another utmost point mounting panel with same mode.

Compared with the prior art, the beneficial effects of the utility model are that: the device finishes the inductor for heat treatment of the roller path through one-time processing, improves the efficiency of part production, can save energy, and can avoid the influence of multiple times of heating on process control.
