Abstract
The utility model relates to an ion nicarbing stove, composed of a stove base disc, a stove body, a stove top case, a cathode support base and a graphite resistor support rack. The utility model is characterized in that a wire connection pin and the support rack are arranged on the stove base disc, a plurality of graphite resistors on the support rack are connected by a plurality of layers of thin iron sheets, and a heat insulation screen is arranged between the graphite resistors and the stove body. Work pieces are connected with cathode, the ion nicarbing stove can generate glow discharge between a cathode support seat and an anode of the stove body after high pressure electricity is added and can process the nitridation of the surfaces of the work pieces, additionally the graphite resistors are heated, gas which contains carbon is put in and can process the ion carburization of the surfaces of the work pieces, and the functions of stoves can be added. Ion carburization is used and the time of carburization can be shortened, work efficiency can be enhanced, and energy can be saved.
Description
A kind of ion carbonitriding multipurpose furnace, adopting this stove can be that workpiece surface is carried out thermo-chemical treatment to workpiece surface carburizing treatment, nitriding treatment, belongs to a kind of chemical heat treatment furnace.
China has thousands of glow ion nitrogen furnaces, because this technology of nitrogenize (comprising ion nitriding) only accounts for sub-fraction in the thermo-chemical treatment field, more than 50% is carburizing treatment and account for thermo-chemical treatment, therefore these glow ion nitrogen furnace equipment mostly do not obtain fine utilization, the higher producer of plant factor also can only reach 20%, some only drove several stoves in one month, have in addition close for a long time and put.This stove is by furnace hearth plate, body of heater, the furnace roof shell, cathode bearing and vacuum suction device are formed, it is to place body of heater on furnace hearth plate, place the furnace roof shell on the body of heater, have some viewing windows on the body of heater, cathode bearing is housed in the middle of the furnace hearth plate, one cover vacuum extractor is arranged under the furnace hearth plate, above-mentioned glow ion nitrogen furnace power supply adopts high voltage direct current, power supply is connected with cathode bearing, body of heater connects positive pole, workpiece connects negative electrode and add high voltage direct current between negative electrode and anode, can puncture the rarefied gas ionized gas when voltage reaches a certain numerical value, produce the glow discharge heated parts, general glow ion nitrogen furnace furnace temperature is about 500 ℃, want well to bring into play the effect of glow ion nitrogen furnace, one important channel enlarges its function exactly, is the ion bombardment multipurpose furnace as transforming nitriding furnace, and considers from a long-term, carburizing is one of main direction of heat treatment technics development from now on, and it has the not available advantage of other heat treatment mode.
The purpose of this utility model is the function that increases ion nitriding furnace, makes the nitrogenize of nitriding furnace energy, again can carburizing.
Ion carbonitriding stove described in the utility model is made up of furnace hearth plate, body of heater, furnace roof shell, cathode bearing etc., it is characterized in that placing on the furnace hearth plate body of heater, place the furnace roof shell on the body of heater, terminal stud, resting support are housed respectively on the furnace hearth plate, use the some graphite resistances of bolting on the resting support, terminal stud is connected with flexible materials with graphite resistance, between graphite resistance and the body of heater thermoscreen is arranged, and thermoscreen is also arranged between furnace roof shell, furnace hearth plate and the graphite resistance.
Above-mentioned terminal stud adopts the multi-layer thin iron sheet to be connected with graphite resistance, also can adopt the multilayer copper sheet, or many iron wires, and flexible materialss such as many copper wires connect.
And above-mentioned thermoscreen is with iron plate the aluminosilicate refractory fiber felt to be fixed between body of heater and the graphite resistance, between with iron plate the aluminosilicate refractory fiber felt being fixed therein too between furnace roof shell, furnace hearth plate and the graphite resistance.
Above-mentioned this ion carbonitriding stove, cathode bearing is also arranged on the furnace hearth plate, body of heater connects positive pole, workpiece connects negative electrode, between negative electrode and anode, add high voltage direct current, when reaching a certain numerical value, voltage can puncture the rarefied gas ionized gas, produce the glow discharge heated parts, general glow ion nitrogen furnace furnace temperature is lower, can not carry out carburizing treatment, so in nitriding furnace, add graphite resistance, improve furnace temperature with the graphite resistance heating, furnace temperature is reached about 100 ℃, carbonaceous gas is put into stove, just can carry out ion carburizing, glowdischarge carburizing to workpiece surface handles, make this stove energy nitriding treatment workpiece, can handle workpiece by ion carburizing, glowdischarge carburizing again, increased the function of workpiece, adopt the aforesaid method ion carburizing, glowdischarge carburizing can shorten carburizing time, improved work efficiency, saved the energy.
Because the furnace temperature of above-mentioned nicarbing stove improves, increasing thermoscreen between body of heater, furnace roof shell, furnace hearth plate and graphite resistance is to make in the stove to be incubated, and improves thermo-efficiency.
The advantage of this ion carbonitriding stove is that this stove can carry out nitrogenize to workpiece, can carry out ion carburizing, glowdischarge carburizing to workpiece again, carries out carburizing with aforesaid method and can shorten carburizing time, improves work efficiency and save energy.
