What is an inner hole induction hardening machine?

  This complete inner hole induction hardening process is as follows: Robotic hand gripping induction coil fixture, the fixture holds two loads and two inductors at the same time, so that to complete these two different diameters inner hole induction quenching process. The robot moves the positioning process for 3 seconds, the total of 18 seconds for the heating water spraying process, 8 beats in total, and 168 seconds to complete a surface φ26 with 8 holes with an arc surface. The robot rotates and moves the load induction coils. The positioning process is 5 seconds, another φ35 hole is heated, and the heating and water spraying process are 18 seconds in total; the total time to complete a single piece is ≤ 4 minutes.

How to do the inner hole induction hardening?

  • The basic theory of the circuit has not changed much, because of the use of new power devices, the circuit and the implementation of technology have a great development;
  • In power rectifier and inverter circuit, module devices are used to replace single power devices. In order to achieve greater power, solid station induction heating machine power devices are used in series or parallel.
  • The control circuit and protection circuit adopt a digital integrated circuit and special-purpose integrated circuit, which simplifies the circuit design and improves the reliability of the complete induction heating system.
  • New circuit components, such as non-inductive capacitor module, non-inductive resistance, power ferrite application, etc.
  • The frequency range is wide, ranging from 0.1 to 500kHz, covering the range of medium frequency, high frequency, and super audio solid state induction heating machine.
  • High conversion efficiency and obvious energy saving.
  • The whole unit is compact and can save 66% to 84% space compared with the valve equipment.
  • Perfect protection circuit, high reliability;
  • Inside the power supply, no high voltage at the output end, and high security.
