Description
Technical field
The utility model device is a kind of sprocket wheel induction heating device, particularly to large modulus sprocket wheel induction heating device.
Background technology
Gear induction quenching is compared with carburizing, nitriding, have energy-conservation, save alloying element, with short production cycle, work situation good and can the advantage such as online production, along with the optimization of sprocket wheel induction hardening process, it is widely used in Application Areass such as lathe, automobile, tractor, locomotive and rotating bearings.Sprocket wheel class induction quenching just starts the thirties in 20th century, and start most to adopt single-frequency induction heating, but heats is bad, frequency is high, tooth top burning, and roller seating space does not have heat; Frequency is low, and roller seating space exists quench-hardened case, but tooth top does not but have.The gear dual-frequency p-code method adopted before the nineties in 20th century in two inductor blocks, carries out preheating and quenching respectively with two kinds of power supplys, and operation extremely bothers, and occupation area of equipment is large, and cost is high; In recent years, gear dual-frequency p-code then adopted two power supplys to carry out heating quenching in an inductor block simultaneously, was called SDF, but this equipment manufacturing cost is expensive, is not suitable for large-scale popularization.
Summary of the invention
For above deficiency, the utility model device provides a kind of large modulus sprocket wheel induction heating device.
The utility model device mainly comprises circular ruhmkorff coil, coil support frame, positive pole web plate, negative pole web plate, this device front end is provided with circular ruhmkorff coil, circular ruhmkorff coil is made up of rectangle copper pipe, inside is provided with cooling water channel, water inlet pipe and rising pipe is respectively arranged with at circular ruhmkorff coil two ends, top is welded with positive pole web plate respectively, negative pole web plate, circular ruhmkorff coil is fixed by screws on the coil support frame at rear, the plugboard that wire is connected to coil support frame inside is connected with the trip switch of outside, circular ruhmkorff coil and low-frequency power is controlled by switching trip switch, intermediate frequency power supply, the connection state of high frequency electric source.
This use new device comprises following technical scheme: be fixed on coil support frame by the circular ruhmkorff coil be applicable to, connect water inlet pipe and rising pipe, sprocket wheel is fixed in the middle of circular ruhmkorff coil, pass into water coolant, circular ruhmkorff coil is prevented to be melted, ensure the normal use of circular ruhmkorff coil in heat-processed, first trip switch is connected high frequency electric source, heating 1-2S, turn off trip switch, air cooling a few second, heat is conducted to roller seating space direction by thermal conduction by tooth top, thus decrease the temperature difference of tooth top and roller seating space, then intermediate frequency power supply is connected, heating certain hour, until heat complete, disconnect trip switch, sprocket wheel is fallen into the water and quenches, and the water coolant passed into is closed.
The advantage that the technical scheme that the utility model device provides is brought and positively effect:
1), this device change induction heating power time only need switch trip switch, without the need to changing ruhmkorff coil, simple to operate, convenient to use.
2), compared with synchronous double-frequency induction heater, occupation area of equipment is little, and working conditions requires low, and cost is low.
