Intelligent Inductive Heating Equipment For Metal Machining And Surface Treatment

Product Description

The induction heating machine is an advanced device that efficiently converts electrical energy into heat energy based on the principle of electromagnetic induction.

It can accurately heat various metal workpieces and is widely applied in multiple industrial fields, especially playing a crucial role in metal heat - treatment processes.

Application:
A. Heating (hot forging, hot fitting and smelting):
1 Hot forging aims to fabricate the work pieces of certain temperature (different materials require different temperatures) into other shapes through forging press with the help of punch press, forging machine or other equipments, for instances, hot extrusion of watch case, watch flan, handle, mold accessory, kitchen and table ware, art ware, standard part, fastener, fabricated
mechanical part, bronze lock, rivet, steel pin and pin.
2. Hot fitting refers to the connection of different metals or metals with nonmetals through the heating based on the principle of hot expansion or hot smelting, for instances, embedded welding of copper core of computer radiator with aluminum sheet and speaker web, compound of steel and plastic tube, sealing of aluminum foil (tooth paste peel), motor rotor and sealing of tubular electric heating element.
3. Smelting mainly aims to melt the metal into liquid by using the high temperature, which is mainly applicable to the smelting of iron, steel, copper, aluminum, zinc as well as various noble metals.
B. Heat Treatment (surface quench):
It is mainly aims to change the rigidity of the metal materials through the heat treatment to work pieces. Detail applications are
stated as follows:
1. Quench for various hardware and tools, such as plier, wrench, hammer, ax, screwing tools and shear (orchard shear).
2.Quench for various automobile and motorcycle fittings, such as crankshaft, connecting rod, piston pin, chain wheel, aluminum
wheel, valve, rock arm shaft, semi drive shaft, small shaft and fork.
3. Various electric tools, such as gear and axes.
4. Quench for machine tools, such as lathe deck and guide rail.
5. Quench for various hardware metal parts and machined parts, such as shaft, gear (chain wheel), cam, chuck and clamp etc.
6. Quench for hardware molds, such as small-size mold, mold accessory and inner hole of mold.
C. Welding (braze welding, silver soldering and brazing)
It mainly aims to melt the solder by heating it to a certain temperature for the purpose of connecting two types of metals of the same material or different materials.

The working principle of the induction heating machine

The working principle of the induction heating machine is based on the phenomenon of electromagnetic induction.

When an alternating current (AC) flows through the induction coil, it generates an alternating magnetic field around the coil.

The strength and direction of this magnetic field change continuously with the frequency of the alternating current.

When a metal workpiece is placed within this alternating magnetic field, the changing magnetic flux through the workpiece

induces an electromotive force (emf) according to Faraday's law of electromagnetic induction. This induced emf causes the

formation of closed - loop electric currents, known as eddy currents, within the metal workpiece.Since metals have electrical

resistance.
