Abstract
The utility model discloses an ion vulcanizing apparatus comprising a stove body 1, an anode plate 3, a cathode plate 5 and a high-voltage direct current power supply 11. A sulphur volatilizing chamber separated from a workpiece machining chamber by a baffle plate 6 is arranged in the stove body and is provided with a sulphur volatilizing device 8 having an electric heating device. A stove body heating device 2 is also arranged in the stove body. The utility model has the advantages of uniform temperature inside the workpiece machining chamber, controllable sulfur gasifying concentration, normal glow generation, no damage to workpieces and the assurance of normal sulfurizing machining operation.
Description
The utility model relates to metal surface treating device, relates in particular to metallic surface ion vulcanizing equipment.
Present used ion vulcanizing equipment, mostly be to utilize ion-nitriding furnace or similar devices, carry out the ion sulfuration of metallic surface with the gas source of the gas, Chinese patent specification sheets CN85106828A discloses a kind of ion vulcanizing equipment that uses the solid source of the gas, this equipment is in solid sulfur and part to be processed in the reaction chamber together, the DC high-voltage power supply of utilizing stove inner anode plate and negative plate to add produces high-voltage electric field, forms glow discharge heating of metal workpiece and solid sulfur, and make the solid sulfur gasification, form sulfurized layer on the metal works surface.But because solid sulfur is constantly volatilized, parameters such as vacuum tightness in the stove and electric current and voltage have been destroyed, and the concentration of sulphur gas can not control, and makes aura can not normally form or produce arc light, the damage workpiece, because aura heated parts, heat solid sulphur causes sulphur gas to form earlier simultaneously, and workpiece does not arrive curing temperature, easily cause sulphur gas to meet the condensation knot, sulfurizing processing can't be carried out.
It is controlled that the purpose of this utility model provides a kind of solid sulfur gasification concentration, and it is even normally to produce the interior temperature of aura and stove, the ion vulcanizing equipment that metal surface sulfurizing processing can normally be carried out.
In order to achieve the above object, the utility model adopts following structure, sulphur volatilization chamber is set in vacuum furnace body, and separate by dividing plate and workpiece process chamber, sulphur volatilization chamber is communicated with by pipeline with the workpiece process chamber, sulphur volatilization is indoor to be provided with a solid sulfur volatilization device that has electric heater, between the positive plate of workpiece process chamber and body of heater well heater is set, the electric heater of solid sulfur volatilization device and body of heater electric heater be connected one exchange or direct supply on.
Sulphur volatilization chamber is enclosed mutually with dividing plate by the part of body of heater and is formed.
During sulfuration processing work; vacuum pump feeds shielding gas after making the vacuum tightness that reaches required in the vacuum oven; open high-voltage DC power supply, the workpiece process chamber produces glow discharge, heating of metal workpiece in stove; open the body of heater electric heater simultaneously; after workpiece and reaction chamber reach curing temperature, open solid sulfur generating unit well heater, make the solid sulfur gasification volatilization in the solid sulfur volatilization device; and enter the workpiece process chamber, thereby finish the sulfuration of metal works by pipeline.
Because the utility model has adopted above-mentioned double-chamber structure to make sulfuration processing can reach the gas-dynamic balance, kept the stable of vacuum tightness, the simultaneously set solid sulfur volatilization device electric heater and the electric heater of body of heater make the processing room temp even, do not produce temperature head, and the gasification concentration of solid sulfur is controlled, normally produce thereby reached aura, do not damage workpiece, the purpose that sulfurizing processing can normally be carried out.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Fig. 1 is this practical structural representation.
As can be seen from Figure 1, the utility model comprises solid sulfur volatilization device 8, AC power 10, high-voltage DC power supply 11, vacuum pump 12, the protection gas cylinder 13 of body of heater 1, body of heater well heater 2, positive plate 3, negative plate 5, dividing plate 6, pipeline 7, charged well heater.In vacuum oven, be provided with sulphur volatilization chamber and by dividing plate 6 and workpiece process chamber every, opening sulphur volatilization chamber is communicated with by pipeline 7 with the workpiece process chamber, starting vacuum pump 12 makes the vacuum oven internal pressure reach the working vacuum degree of 0.1～100pa, unlatching is connected the high-voltage DC power supply 11 of negative plate 5 and positive plate 3, in vacuum oven workpiece process chamber, produce glow discharge, heating is placed on the metal works 4 on the negative plate 5, open AC power 10 simultaneously, connect body of heater electric heater 2 heating whole work-piece process chamber, after treating that workpiece 4 and whole work-piece process chamber temperature reach the solid sulfur curing temperature, connect the electric heater of solid sulfur volatilization device 8 again, make fixedly sulphur volatilization, gasification evaporable sulphur gas enters the workpiece process chamber by pipeline 7, form the gas-dynamic balance, thereby make metal works 4 finish surperficial sulfurizing in stable vacuum tightness and under the glow discharge, the temperature of metal works 4 is by thermopair 9 monitorings.
