In order to improve the processing efficiency of the welded brake shoe, reduce the energy consumption and facilitate the positioning, the utility model proposes a high-frequency quenching sensor device that simultaneously heats the brake shoe and brake shoe.
The device is characterized as follows: the device is composed of four quenching inductors, each of which is a group, and the two inductors in each group are connected in electric series, and the first group of inductors and the second group of inductors are connected in electric parallel. According to the structure of the brake shoe, the utility model designs a new type of inductor, realizes 4 series and parallel branch inductors on a connecting plate, formulates the energy distribution according to the different size of the quenching area in different parts, makes the brake shoe locate at a time and heat quenching at the same time, and guarantees the uniform heating in all places. The utility model has a simple inductor structure and can complete the quenching requirements of four parts of the brake shoe by clamping at one time, so as to improve the efficiency and save energy consumption. The electrical parameters of the high frequency induction quenching power supply device for brake brake shoes are as follows:
Model: YFL - 60
Input power: 60
Input voltage: three-phase 380V 50-60hz
Oscillation frequency: 15-25khz 25-35khz
volume
Main control cabinet 550mm 450mm 1260mm
Transformer cabinet 500mm 800mm 580mm
Equipped with induction hardening tooling fixture, timing, mobile, rapid scanning, fast falling function, realization of brake shoe controllable quenching heat treatment operation, artificial time-consuming inefficient, the tooling design, greatly increase the working efficiency of the brake shoe quenching, to solve the cost and create the benefits, is a good choice.
