Technology of stannic secret alloy already was popularized to apply widely in a few factories, it makes mould quality gained effective control not only -- real ground is accomplished ahead of schedule precaution, beforehand is eliminated, and shortened greatly the development cycle of new product and the cycle that breed batch produces, improve product quality for the factory, develop, occupational and consolidate the market, made the contribution that cannot underestimate. Examine in mould chamfer in, is the method that uses normally: ? Admonish  of ⒀ of lame to fold of Tuan of ⑸ of every ǔ to fold is tranquil ② of? of Ji of Yan of canister of Yue of Hu of skirt ぞ M uses salt, candle or the material such as gesso irrigates an appearance, examination chamfer is wrong move. These groovy methods control dimension of the mould of a few simpler forging chamfer effectively, but tall to a few complex degree forging, dimension of its mould chamfer detect completely hard, such certainly will influences produce plan, raise manufacturing cost. Combine a plant at this point production is large and complex the characteristic of kind of forging reachs his to be in production is actual medium circumstance, to the mould examine the exploration that control had development and research, fumble the new method that gives to solve this one difficult problem- - technology of stannic bismuth alloy. This technology and photographs of afore-mentioned law of groovy check proved recipe are compared, is its most outstanding advantage: ?

Of stannic bismuth alloy make up reach its main physics function already knocked broken the stannum that becomes 60 × 60(mm) , bismuth two slug, mix equably by certain percentage (its per cent is fair value, cannot make up at will) hind, put already heated of 350 ℃ add boiler or other to heat inside container. Fuse in its in the process, the agitate that break the ground reachs otherwise even. If have dross, want eliminate. Next, it is fluid of this even alloy frit in angle iron or channel pouring into strip, in order to have pouring appearance when with. Alloy of this stannum bismuth falls in normal temperature, show solid state, silvery white, melting point is low have 1350C only, hardness is low, shrinkage of solid fluid bulk is 0.

051% , have stronger osmotic. 2.

The Yuan manage of technology of stannic bismuth alloy examines in mould chamfer in, basically apply the minimum of shrinkage of the bulk between fluid of solid of stannic bismuth alloy, characteristic that can think the bulk between solid fluid is changeless approximately, the appearance that irrigates outpour chamfer, be opposite next this appearance have each the exterior, place measure (the hot dimension of forging) the integral examination that reachs geometrical appearance to wait, discover the inadequacy that machine or designs from which. 3.

Appearance of stannic secret alloy in mould chamfer pouring the first pace, size of basis chamfer cubage takes secret of right amount stannum to join a metal bar, put already heated of 135 ℃ add boiler or other to heat in container, in its the agitate that break the ground reachs the otherwise in fused process its are even. The 2nd pace, need pouring appearance the mould heats equably 160-200 ℃ (decide according to module size, big person temperature low) . The third pace, irrigate saline method with convention, hang down the mould erect case (the) on day of the opening that irrigate salt, the edge irrigates saline mouth pouring alloy liquid, till model groove is irrigated full till. The 4th pace, wait for a mould to cool completely to room temperature hind, use proper method to open a mould, take out shape (appearance cannot disconnect) . The 5th pace, examination appearance whether to accord with model groovy appearance, if can bona fide report chamfer, hand in check to detect if; is not accorded with, new and pouring till accord with model groovy appearance. The 6th pace, detect according to making check result, undertake proper processing to the mould. Be in pouring the item: that the attention answers in the process? M of ＞ of a keeper of domestic animals is short of talk in one's sleep of ＞ of rapid of Ze of source of secondary Fu of  of caries of  of arrogant of box Guang Bao especially postscript of  of difficult  of rank ⒊ Bao warmths ablaze ② of? of bosom holding the post of  wants pouring mould to must handle ③ of good crackle; first before its are pouring must stannic Q, alloy odd-come-short from pouring clear in the mould after chamfer appearance of clean; ④ cannot have fill flash of malcontent, remain too big, bend, local be out of shape wait for immediate impact to detect greatly the blemish of the result. 4.

Technology of stannic secret alloy examines to apply 　 mediumly in the mould (the die forging model with good to already was being machined 1) , use pouring appearance of stannic secret alloy the method will check its quality. (2) uses the quality of rehabilitate of mould of its test and verify, be in namely already repair is good model in groove, irrigate appearance of alloy of outpour stannum secret, again right this appearance undertake detecting. (3) is used pouring method of stannic secret alloy comes to two kinds distinguish or a variety of wait besides specific measure outside differring, the forging mould that other agrees basically. (4) is overall to straightening die dimension the control that wait, it is the key that how has repair certainly. Right complex kind of straightening die of forging, its rehabilitate difficulty is quite great, repair quality also assures hard. The pattern of stannic secret alloy that notes this pattern is irrigated before using repair the method can try to solve. CNC Milling CNC Machining
