The electric heating device comprises a water tank, an electric control box and a heating copper pipe mechanism, a fixing frame is fixedly installed on the inner surface wall of the bottom of the water tank, an air cylinder is fixedly installed on the top of the fixing frame, and the output end of the air cylinder is in transmission connection with a containing base through a linkage frame; a connecting box is fixedly installed on the outer surface wall of the vertical end of the electric control box, the heating copper pipe mechanism comprises a plurality of sets of heating copper pipes, each heating copper pipe comprises a conduction end and an opening and closing end, and the conduction ends and the opening and closing ends are slidably connected with the inner surface wall of the connecting box through matching grooves and sliding grooves correspondingly; a conduction piece is fixedly installed on the inner surface wall of the matching groove, and a gear rod is fixedly installed at the open end of the opening and closing end. The heating copper pipes of the corresponding sizes are rotated through the corresponding gear rods, the instant heating copper pipes do not need to be disassembled and assembled repeatedly when gears of multiple sizes are machined, and the universality of the electric heating device for industrial production quenching is improved.

Description

technical field [0001] The invention relates to the technical field of quenching of industrial parts, in particular to an electric heating device for quenching in industrial production. Background technique [0002] The purpose of gear quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, and durability of the steel. Wear resistance, fatigue strength and toughness, etc., so as to meet the different requirements of various mechanical parts and tools. [0003] Put the workpiece into the inductor (coil), and when an alternating current of a certain frequency is passed into the inductor, an alternating magnetic field is generated around it. The electromagnetic induction of the alternating magnetic field causes a closed induced current in the workpiece—eddy current. The distribution of induced current on the cross...

Problems solved by technology

[0004] At present, most of the existing industrial gear quenching uses high-frequency quenching machines, and most of the high-frequency quenching machines use electric heating copper tube mechanisms as electric heating devices, but the existing electric heating devices for industrial production quenching still have shortcomings. First, the existing The industrial quenching electric heating devices mostly use independent heating copper tubes, and the independent heating copper tubes are set to match the diameter of the batch of gears, so that when processing multiple sets of gears with different sizes, it is necessary to carry out Repeated disassembly and assembly of the heating copper tube is inconvenient to operate, thereby reducing the versatility of the electric heating device for industrial production quenching; secondly, the gears in the existing industrial production quenching will move to the water tank for cooling after the heating is completed. Reset, and finally remove the gear manually, it is easy to touch part of the heat conduction component during manual operation, the residual temperature on the heat conduction component is easy to burn the hands of the operator, and the operation is more dangerous, thus reducing the safety of the electric heating device for quenching in industrial production safety
