Induction heating system and method for rapid curing of silicon steel self-adhesive coating iron core

Abstract

The invention discloses an induction heating system for rapid curing of a silicon steel self-adhesive coating iron core. The induction heating system comprises a conveying roller table; an induction heating device comprising a cylindrical induction heating coil having a hollow cavity and a temperature measuring element, wherein the induction heating coil adopts 6-20KHz intermediate frequency to perform induction heating of the silicon steel sheet; a feeding and discharging device; a loading and unloading device which is arranged to transport the stacked mold directly below the induction heating coil in the horizontal direction and to transport the stacked mold into the hollow cavity of the induction heating device in the vertical direction or to remove the stacked mold from the hollow cavity after the induction heating is completed; and a control device which is respectively connected with the conveying roller table, the feeding and discharging device and the loading and unloading device to control their respective actions and is also connected with the induction heating coil and the temperature measuring element to control the induction heating process.

Description

technical field [0001] The present invention relates to a system and method, and more particularly to a heating system and method. Background technique [0002] Modern mass-produced motor core stacking methods mainly include bolt connection, welding, riveting and bonding. The bonding method is to assemble and form silicon steel sheets coated with self-adhesive coating by surface fixing, so The stacking and forming process has the advantages of no pollution, high iron core fixing strength, low magnetic vibration noise, and high iron core efficiency. It is especially suitable for situations where other fixing methods will cause distortion or insufficient rigidity, and are not convenient for riveting or welding. [0003] The current conventional application guidance for self-adhesive coated silicon steel sheets is to take out the iron core punched by the punch press (actually loose sheets at this time), load the upper clamp with a pressure of 6-30bar, and send it to the heating...

Problems solved by technology

If a higher frequency is selected, the depth of the skin layer will be reduced and the heating efficiency will be higher, but the temperature difference between the surface and the interior of the heated workpiece will be larger during the heating process
