Due under same circumference condition, the bottom of described bonnet be similar ellipticity or circular time, floorage is comparatively large, then the volume in bonnet is relatively large, can increase each batch of treatable workpiece amount.
In order to make the temperature in bonnet rise fast, improve heating efficiency, described resistive band has two at least.
Conveniently chassis is pushed to immediately below lifting support, described first chassis and described second chassis are respectively arranged with handrail.
Because electrically heated process is a veryer long process, in order to reduce the work strength of workman, this device carries out Automated condtrol, and also comprise automatic control device, described automatic control device comprises:
Operated key, for needing according to the thermal treatment of workpiece the target temperature arranging described bonnet, and sends with instruction type;
Control module, for receiving described instruction and controlling the descending operation of described lifting support according to this instruction and control described first chassis and described second chassis enters or exit described bonnet;
Temperature detecting module, for detecting the temperature in described bonnet, and sends to control module by described temperature;
Distance induction module, for detecting the distance of described first chassis and described second chassis and described lifting support, and sends to control module by described distance;
Lifting support power plant module, is arranged on lifting support, moves up and down on lifting support for driving described bonnet relative to ground;
Chassis power plant module, is arranged on the track, for promoting described first chassis and described second chassis moves in orbit.
Wherein, described lifting support, described first chassis and described second chassis are provided with power plant module.
Wherein, described control module is micro-chip.
Beneficial effect: bell-type electric heater unit of the present utility model adopts being used alternatingly of two chassis, take full advantage of the remaining temperature in removable heating bonnet, make to be shortened 70% by the heated parts heating-up time, be highly suitable for workpiece process in enormous quantities, shorten heat treatment time, save energy, improves working (machining) efficiency; Adopt the bonnet of similar oval structure, increase bonnet volume, improve once heat treated workpiece amount; Adopt automatic control device, decrease the labor capacity of workman, reduce cost of labor.
