Abstract
There is disclosed a electromagnetic induction heating plate, which comprises a frame and a heating metal plate on the frame. On the heating metal plate is disposed an induction coil for inducing the heating metal plate to produce vortex. The induction coil is winded by stranded enamel wire and on the induction coil is disposed a high-frequency magnetic-inductive piece. The thickness of the heating metal plate is 1 to 3 mm. Between the induction coil and the heating metal plate an asbestos sheet for heat insulation is disposed.
Description
Technical field
The invention belongs to a kind of welder, be used for the welding of plastic conduit.
Background technology
Butt fusion welding is one of main welding method of plastic conduit.Its employed welding equipment is a butt fusion welding machine, and the core component of welding machine is a heating plate.The effect of heating plate is heating and molten plastic pipeline end face, thereby reaches the purpose of welding.What the preheating method of heating plate adopted at present is the resistance wire heating, and this makes that the volume and weight of heating plate is all bigger, and the preheating speed is unhappy.This does not cause by the resistance wire heating efficiency is high.Therefore, be necessary to develop the high heating plate of the heat efficiency, to reduce the volume and weight of heating plate.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of heating efficiency high electromagnetic induction heating plate, with the shortcoming of the resistance wire preheating method that overcomes heating plate in the prior art.
For solving above-mentioned technical problem to be solved, electromagnetic induction heating plate of the present invention comprises framework and the metal heater plate that is provided with on the framework.Described metal heating plate is provided with induction coil, is used to make metal heating plate to induce eddy current.
Described induction coil is by strands enamelled wire coiled; Described induction coil is provided with high frequency magnetic conduction bar.
The thickness of described metal heating plate is between 1 to 3 millimeter.
Be provided with between described induction coil and the metal heating plate and be used for heat insulation asbestos board.
Compared with prior art, the present invention has following beneficial effect: because electromagnetic induction heating plate of the present invention has adopted induction heating technique, the heat efficiency is very high.Through facts have proved, in identical electric input power, only be two minutes the warm-up time of electromagnetic induction heating plate of the present invention, and the heat efficiency is up to 85%, and the volume and weight of heating plate also significantly reduces simultaneously.
