Description
Technical field
The present invention relates to powder metallurgical technology more particularly to a kind of dressing sieve protective devices for powder metallurgy.
Background technology
Wolfram steel, also known as hard alloy refer to the sintered composite materials at least containing a kind of metal carbides composition, carbonization
Tungsten, cobalt carbide, niobium carbide, titanium carbide and ramet etc. are the common ingredients of wolfram steel.The production of wolfram steel belongs to PM technique,
Metal powder is as produced or by the use of metal powder (or mixture of metal powder and non-metal powder) as raw material, by compacting
Blank is formed, sintering furnace is then fed into and is heated to certain temperature (sintering temperature), and is kept for the regular hour (soaking time), then
It cools down, so as to obtain the wolfram steel blank of required performance, finally again obtained wolfram steel blank is carried out " examining (non-destructive ultrasonic
Wave inspection detects) → blank size precision inspection → electrical discharge machining (or wire cutting shaping) → polishing → polishing → inspection → beats
A series of processing such as mark → packaging " can dispatch from the factory.Wherein when producing the powder as blank stock, it is necessary to which metal powder will be obtained
The auxiliary material of end/non-metal powder and improvement powder compacting and plasticity is mixed and stirred, and is then sieved by dressing sieve machine
Choosing, since powder size is smaller, activity is bigger, thus the easier oxygen by air in its surface aoxidizes, and is also easier to
Water suction, thus its storage and transport are all inconvenient, if once powder excessive oxidation or water suction excessively may result in what is produced
Wolfram steel quality is affected.
The content of the invention
For the deficiency in the presence of the prior art, the present invention provides a kind of dressing sieves for powder metallurgy to protect dress
It puts, can effectively solve the problems, such as that powder raw material is easily aoxidized or hygroscopic, so that storage and transporting more convenient, also protect
Product quality is demonstrate,proved.
To achieve the above object, present invention employs following technical solutions：
A kind of dressing sieve protective device for powder metallurgy, bung including charging basket, mating with charging basket and is arranged on
Gas-tpe fitting mechanism on bung, wherein：The charging basket is the container of upper opening and its exterior is equipped with handles；In the bung
Equipped with the sealing ring to match with charging basket opening, the bung is equipped with feed inlet and air admission hole：
The gas-tpe fitting mechanism includes the first connecting tube being fixed in air admission hole, is threaded in the first connecting tube back of the body
The second connecting tube from air admission hole one end and the 3rd connecting tube that the second connecting tube deviates from first connecting tube one end is fixed in, institute
The side wall away from second connecting tube one end for stating the 3rd connecting tube is equipped with breach and the breach from end into the 3rd connecting tube
Portion extends, the outer diameter of the 3rd connecting tube from breach opening to breach closure at taper off variation, the 3rd connecting tube
Outside is cased with slidable sliding sleeve, and sliding sleeve internal diameter matches with outer diameter in the middle part of the 3rd connecting tube so that sliding sleeve can drive when sliding
Dynamic 3rd connecting tube sets fatiscent one end, and mandrel is shunk thereto.
The principle of the present invention is：In use, first install bung to charging basket, then by the powder raw material prepared from charging
Mouth is packed into charging basket, and appendix the 3rd connecting tube of insertion of noble gas source then is equipped with breach one end, is then slided
Sliding sleeve causes the 3rd connecting tube to set fatiscent one end to contract so as to which appendix be clamped, and inert gas can be from air inlet
It is protected in into charging basket and to powder raw material.
Compared with the prior art, the present invention has the advantages that：By access inert gas with realize to raw material into
Row protection, effectively prevents raw material and aoxidize or is absorbed water and influence product quality；The configuration of the present invention is simple simultaneously, by sliding
Set may tighten or loosen the appendix of source of the gas, easy to operate, and be applicable to various sizes of appendix, and adaptability is wider.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the partial enlarged view of part A in Fig. 1.
Specific embodiment
The technical solution in the present invention is further illustrated with reference to the accompanying drawings and embodiments.
As shown in Figure 1, the present invention proposes a kind of dressing sieve protective device for powder metallurgy, including charging basket 1, with expecting
1 mating bung 2 of bucket and the gas-tpe fitting mechanism being arranged on bung 2, wherein：
The charging basket 1 is the container of upper opening and its exterior is equipped with handles 11；It is equipped in the bung 2 and is opened with charging basket 1
The sealing ring 21 that matches of mouth, wherein bung surrounding have cover rim to be enclosed in charging basket open outside, the bung 2 be equipped with into
Material mouth 22 and air admission hole 23：
As shown in Fig. 2, the gas-tpe fitting mechanism includes the first connecting tube 31 being fixed in air admission hole 23, is threadedly coupled
Away from second connecting tube 32 of air admission hole one end and the second connecting tube 32 is fixed in away from the first connection in the first connecting tube 31
