Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to the overall structure schematic diagram that Fig. 1 and Fig. 2, Fig. 1 are a kind of detailed description of the invention provided by the utility model, Fig. 2 is the left view of Fig. 1.
In a kind of detailed description of the invention provided by the utility model, atmosphere sintering furnace mainly includes inner bag 1 and turbulator member 2.
Wherein, inner bag 1 is the important component part of atmosphere sintering furnace, is arranged in the body of heater 3 of atmosphere sintering furnace, and workpiece is just placed in inner bag 1 when sintering, and for accelerating sintering process, the temperature in inner bag 1 is the highest.Inner bag 1 cylindrically or square tube shape can be provided with the thermal insulating door thermally insulated door keeping internal high temperature, be typically made up of graphite in both sides around.When sintering workpiece, need surface of the work and PROCESS FOR TREATMENT gas uniform contact to improve the sintering quality of workpiece, to this end, be typically provided with the air inlet of diverse location on the sidewall of inner bag 1, to ensure atmosphere evenness.
Turbulator member 2 is arranged in inner bag 1, and it is freely rotatable, and when it rotates, the process gas entered in inner bag 1 will be carried out strong agitation so that process gas is dispelled.Concrete, when entering into inner bag in view of process gas at certain or certain several air inlets, the concentration class of process gas is higher, density is relatively big, and just when air inlet sprays, its movement velocity is highly consistent, so can be regarded as " process gas group " by the process gas having just enter in inner bag 1.Obviously, the most of medium powder entrained by " process gas group " all concentrates at one, the least with the contact area of workpiece, is unfavorable for the sintering quality of surface of the work.And when working as high speed rotating and the strong agitation that " process gas group " encounters turbulator member 2, " process gas group " is broken up with regard to moment, is upset, enter and be dispersed into that density is the least, distribution the most extensively and rapidly spreads all over " the process gas cloud " of whole inner bag volume, so " process gas cloud " by easily with the surface Full connected of workpiece, the medium powder carried is broadcasted sowing on surface of the work simultaneously, owing to the distribution of " process gas cloud " is wide, density is more uniform, the medium powder distribution uniform too that therefore surface of the work covers.
Therefore, atmosphere sintering furnace provided by the utility model, by being provided for the turbulator member 2 that process gas is stirred in inner bag 1, make the distribution of process gas more extensively, evenly, thus improve the contact area of process gas and surface of the work, make the sintering degree of surface of the work and treatment effect become more uniform.
About in a kind of preferred implementation of turbulator member 2, for realizing the turbulator member 2 rotation in inner bag 1 easily, the present embodiment is provided with on body of heater 3 and is exclusively used in the driving motor 4 driving turbulator member 2 to rotate.The rotation driving motor 4 is controlled, rotating speed is also adjustable simultaneously, in addition can also rotating, thus by driving motor 4 to drive the mode that turbulator member 2 rotates, depending on (rotating speed, turn to) can be according to the specific requirement of workpiece sintering process so that the working condition of turbulator member 2.
Concrete, owing in body of heater 3, space is narrow, drive motor 4 to be generally located on the outer wall outer surface of body of heater 3, so drive motor 4 can drive turbulator member 2 by the way of power transmission shaft 5 is connected with turbulator member 2.Owing to turbulator member 2 is arranged in inner bag 1, and driving motor 4 to be arranged on the outer wall of body of heater 3, therefore power transmission shaft 5 needs to penetrate the sidewall of body of heater 3 and the sidewall of inner bag 1 successively.

Further, in order to make controller 7 relatively accurately judge the sintering uniformity coefficient of surface of the work, the present embodiment is provided with multiple temperature probe 8 on the inwall of inner bag 1, and each temperature probe 8 is all connected with controller 7 signal.Concrete, temperature probe 8 can detect the temperature of surface of the work, and when multiple temperature probe 8 detects simultaneously, can form the gross area temperature profile of surface of the work.In view of process gas when being dispelled by turbulator member 2 and contacting with surface of the work, the a range of temperature difference certainly will be there is between surface of the work and process gas, two objects with the temperature difference contact with each other, necessarily will produce heat transmission, so transient temperature of surface of the work will change when contacting with process gas, may raise and be likely to reduce.And controller 7 just changes according to the transient temperature at each position of surface of the work detected by each temperature probe 8, form the gross area transient temperature change profile figure of surface of the work, the contact area of surface of the work and process gas, namely the sintering uniformity coefficient of surface of the work can be relatively accurately judged according to this scattergram.
About in the another kind of preferred implementation of turbulator member 2, this turbulator member 2, without the outside driving driving motor 4, when it is arranged in inner bag 1, can rotate automatically.Concrete, this turbulator member 2 is propeller blade, it is arranged at the air inlet on inner bag 1 sidewall, and propeller blade has the spiral flow linear shape of axially inclined certain angle, when this is shaped such that in air inlet the process gas being passed through quickly flowing, the axial impact power of process gas Yu propeller blade can be converted into the torque load being circumferentially distributed, thus promote propeller blade to rotate in a circumferential direction.Being arranged such, turbulator member 2 i.e. may utilize the kinetic energy promotion of process gas and self carries out high speed rotating, is dispelled by process gas, saves the energy of external drive.
Certainly, compared to the mode of driving motor 4 active drive, the passive turbulator member 2 rotated is relatively low, for this to the agitation degree of process gas, the present embodiment is provided with multiple propeller blade on the sidewall of the inner bag 1 of propeller blade, and each propeller blade is uniformly distributed along the axial direction of inner bag 1.So, when process gas pours in inner bag 1 at a high speed by air inlet, each propeller blade can rotate simultaneously, and process gas group is promptly distributed to each corner of surface of the work.
