IGBT shafts gears surface hardening machine

1. Brief introduction of induction hardening machine

Our high frequency induction hardening machine adopts IGBT series and parallel induction heating technology as the core. The induction hardening machine heats the metal work piece to a certain temperature, and then cool it rapidly to change its machine structure to achieve some special mechanical properties.

2.  Technical Parameter of 120kw  Induction Hardening Quenching Machine:

3. Induction Quenching Hardening Machine Application:

(1) For auto parts and motorcycle parts hardening.

(2) For machinery parts, like gears, transmission wheels, axles, shafts, spline shafts, ball stud hardening.

(3) For machine tools quenching, like guide rail machine tools hardening.

(4) For spanner, pliers, CNC machines, hammer, axe hardening etc.

4. Advantages of induction hardening:

(1) High hardening quality: The hardening speed can reach up to 400 mm / min. The fast moving water goes into a double track at the same time.

(2) Energy saving: The induction hardening machine adopts IGBT from & LC series circuit design, saving energy up to 15%-30%.

(3) Low cost: The heating time is short, compared to other heating methods, significantly reducing the amount of metal loss.

(4) Easy for installation: Following the user manual, even non-professional persons can install the induction hardening machine easily.

(5) Stable operation: complete protection, make customers have nothing to worry about.
(6) No harm to the environment: The induction hardening machine uses electricity, producing little waste gas and water.

(7) A little space occupation: The induction hardening machine is portable, and takes up a little space.

(8) High degree of automation: The induction hardening machine can be connected with upper computer and IPC to make the machine operate automatically.

(9) Low failure rate: Components pass strict selection and inspection to assure the equipment to work steadily.

How to choose induction hardeing equipment?

Selection of induction heating frequency: The shallower the heating depth, the higher the frequency.
1. Hardening depth≤1mm, ultrahigh frequency (＞50KHZ), which is generally used for hardening small parts, like small-module gears and shafts with small diameters. ​​
2. Hardening depth 2-4mm, superaudio frequency (25-35KHZ), which is generally used for hardening shafts with large diameters and gears with large and medium modules. ​​
3. Hardening depth ＞4mm, intermediate frequency, which is generally used for diathermy of large parts and surface quenching of large-diameter parts (diameter above 300mm, like rolls).
