Description
Technical field
The present invention relates to high-temperature sintering apparatus field, especially a kind of artificial tooth soft alloy sintering stove.
Background technology
Cobalt chromium hard alloy is the current wide variety of raw material of artificial tooth manufacture field the most in the world, but processes raw material using cobalt chromium hard alloy as artificial tooth, and manufacturing process is complicated, and finished-product material performance has much room for improvement.Development along with PM technique, bright prospects have been shown in the direction that the soft alloy of cobalt chromium processes raw material as artificial tooth, the soft alloy of cobalt chromium is with cobalt and chromium metal dust, pie is become by high voltage units, can carry out machining at CAD/CAM machining center, the artificial tooth leaf-comb processed or crossover need to carry out high temperature anaerobic sintering and form the artificial tooth possessing respective strengths.
The type of furnace that can be used to sinter the soft alloy of chromium in the market is box Muffle furnace, there is Railway Project in box Muffle furnace, one, owing to box Muffle furnace heating element designs is distributed both sides, the thermal treatment zone, there is heating temperature field uniformity the highest, soft alloy is heated inequality in stove, so can be deformed, produces defect ware；Two, box muffle-furnace door designs generally left and right and opens, or opening structure up and down, and a lot of techniques require in the case of needing that high temperature quickly removes material, and the enabling of box Muffle furnace high temperature takes material and can produce the strongest heat radiation, operator are caused health threat；Three; give vent to anger system owing to box Muffle furnace is not provided with protective gas air inlet; soft alloy during high temperature sintering with the oxygenated products oxidative phenomena in air; cause mild alloy artificial tooth defective; if being passed directly into the protective gas such as argon at box Muffle furnace; other meetings of the protection such as argon are constantly discharged from burner hearth, and consumption of air source amount is big, and Financial cost is high.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of artificial tooth soft alloy sintering stove.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of artificial tooth soft alloy sintering stove, including annular furnace heating system, gas air supply system, sintering pan suit system, material carrier platform jacking system, man-machine control system five part forms.
Further, described sintering pan suit system uses the protective atmosphere blood circulation that small one and large one high-temperature ceramics sintering pan forms.
Further, described gas air supply system institute supplied gas is protective gas.
Further, described protective gas is argon.
Further, described material carrier platform jacking system is electric power jacking system.
Further, described gas air supply system is provided with effusion meter.
Further, described gas air supply system is set with system connection by trachea and sintering pan.
Beneficial effects of the present invention: burner hearth heating system of the present invention uses annular-heating, i.e. heating element designs distribution formation one is ring-type, it is enclosed in heated material from all directions, each face making material is heated evenly unanimously, high temperature sintering concordance is effective, solve the heating of traditional box Muffle furnace uneven, easily deform or cracking situation.
Sintering pan of the present invention suit system uses the protective atmosphere blood circulation that small one and large one high-temperature ceramics sintering pan forms; make the protective atmospheres such as argon in suit inner loop; while forming good anaerobic high temperature sintering environment, only consume the protective gas such as argon of trace, effectively reduce production cost.
Material carrier platform jacking system of the present invention uses electric up-down dynamical system; sintering pan suit vertically can be risen to inside high-temperature heating burner hearth during charging; sintering pan suit vertically can be dropped to outside heating furnace during discharging; take out material one time; owing to being vertical lift mode; operator so high-temperature gas will not be radiated operator, will not protect operator's personal safety directly facing high-temperature burner hearth.
Man-machine control system of the present invention uses touch screen PID+PLC control system, heating curves Real time dynamic display, and sintering process curve can be edited and prestore, and sintering data can automatically save, and configures USB interface, remotely can control with PC.

Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings:
Seeing Fig. 1-2, a kind of artificial tooth soft alloy sintering stove, including annular furnace heating system, gas air supply system, sintering pan suit system, material carrier platform jacking system, man-machine control system five part forms.Described sintering pan suit system uses the protective atmosphere blood circulation that small one and large one high-temperature ceramics sintering pan forms; described gas air supply system institute supplied gas is protective gas; described protective gas is argon; described material carrier platform jacking system is electric power jacking system; described gas air supply system is provided with effusion meter, and described gas air supply system is set with system by trachea and sintering pan and connects.
The present invention is by annular furnace heating system, gas air supply system, sinters suit system, material carrier platform jacking system, and man-machine control system forms.Sintering mild alloy artificial tooth, is first put into sintering suit system product, is controlled by man-machine touch screen, and material carrier platform jacking system is slowly increased to sintering suit in annular furnace heating system；Air supply system is passed through argon by pipeline in sintering suit, forms oxygenless gas protection environment；Being controlled by man-machine touch screen, annular furnace heating system begins to warm up high temperature anaerobic sintering；Sintering terminates, and controls material carrier platform jacking system by man-machine touch screen and slowly declines, and opens sintering suit, takes out the soft alloy artificial tooth sintered.
Finally it should be noted that; detailed description of the invention is to further illustrate the present invention and unrestricted; for those of ordinary skills; conversion further can be done in the case of without departing from flesh and blood of the present invention, and all these conversion all should belong to the protection domain of claims of the present invention.
