Abstract
The invention provides a double-frequency induction heating device, which comprises a first induction coil (L1), a first power supply (U1), a second induction coil (L2) and a second power supply (U2), wherein the frequency value of the first power supply (U1) is first frequency f1, and the first power supply (U1) is connected with the first induction coil (L1); and the frequency value of the second power supply (U2) is second frequency f2, and the second power supply (U2) is connected with the second induction coil (L2). The double-frequency induction heating device is used for heat transmission, quenching and tempering, normalizing, tempering and smelting, and enables all outer surfaces of a workpiece to carry out uniform heating.
Description
Technical field
The invention belongs to a kind of heating unit, relate in particular to a kind of double frequency induction heating device that is used for the workpiece induction heating.
Background technology
The existing induction heating device that is used for the workpiece heating, the frequency that its power supply is added on the induction coil all has only a kind of frequency.
But, when the heat treated of the workpiece that is used for the non-rotational symmetry of shape (for example trilateral), because existing workpiece heat induced heating unit only uses when heating for workpiece with a kind of frequency, thereby each position non-uniform temperature that causes workpiece, in, normalizing modified, the tempering heat treatment as heating at workpiece, can cause that some position of workpiece is modified, normalizing, temper number be inconsistent, influences quality product.
Summary of the invention
In order to address the above problem, the purpose of this invention is to provide a kind of double frequency induction heating device, make each appearance of workpiece be subjected to the even heating temperature.
In order to achieve the above object, embodiments of the invention provide a kind of double frequency induction heating device, comprising:
