Embodiment:
See Fig. 5-Figure 10 be processing after finished figure; (high temperature alloy cast housing part drawing)
One, the part operating process and casting fixture of the present invention that adopt this invention processing are described:
Fig. 7 fabricated part is high temperature alloy cast housing part, and material INCOL718, specification 223mm × 147mm × 285mm, after Milling Machining, part thinnest part is about 3mm.As can be seen from the figure part is determined by A1, A2, A33 datum mark in X-direction; Y-direction is determined by B1, B22 datum mark; Z-direction is determined by C11 datum mark.
Part blank design basis 6, three directions datum mark is transferred on false boss by fixture of the present invention and casting low-melting alloy.
The operation instruction of transfer benchmark casting fixture:
Design basis X-direction benchmark A of the present invention, Y-direction benchmark B, Z-direction benchmark C, three benchmark are mutually vertical.
Fixture upper bed-plate 1 of the present invention, locating piece 2 18 and part blank design basis A1, A2, A3 coordinate; On fixture, design basis B1, B2 of locating piece 18, sub-module 2 14 and part blank coordinates; On fixture, on locating piece 1 and part blank, design basis C1 coordinates, and holds out against part blank ensure that on fixture, on each locating piece 1, locating piece 2 18, base 1, sub-module 14 and part blank, datum mark realizes blind-mate by tight lifting pin 1, tight lifting pin 2 16.
Fixture upper bed-plate 1 of the present invention, locating piece 2 18 and fixture datum A depth of parallelism 0.01mm, and the size between A benchmark to show that the structure of part blank and all the other 2 direction sizes fixed select principle the same; Locating piece 2 18, sub-module 2 14 fixture datum B depth of parallelism 0.01mm on fixture; Locating piece 1 fixture datum C depth of parallelism 0.01mm on fixture.By the locating piece 1 on fixture of the present invention, locating piece 2 18, base 1, sub-module 14 by the Reference Transforming of 6 some positions on part blank on design basis A, B, C of fixture.
Have a position in the bottom of fixture upper surface of the present invention at casting process platform groove 20 place, surface, six, this place forms strict form and position tolerance in X, Y, Z tri-directions and jig Design benchmark A, B, C equally, and roughness is lower than 0.8 ц m.Low-melting alloy is filled into this position by the present invention, and will obtain the metal coupling outside two housings after alloy cooling, the present invention is referred to as false boss.
Six faces (see Fig. 3) and the jig Design benchmark of the present invention of above-mentioned casting process platform groove retrain, as long as ensure the mobility of alloy in alloy casting process, after casting, obtain six all sizes in face that process area can copy casting process platform groove completely.Push away forward the relative position of design basis A, B, C of just replicating fixture → replicate six alignment pin relative sizes → replicate six datum mark points on part again.
After having had process area, the clamping of part and location have become simply, only process area six faces and fraise jig reasonably need be put and are compressed and just can carry out machining.
Two, low-melting alloy filling is carried out to part poor rigidity position
For chamber portion does not have intensity in the middle of this housing part blank, add and more surely there will be the problem such as cutter relieving, knife man-hour, in order to address this problem, the mode that the present invention takes is to chamber portion filling low-melting alloy.The metal material that this part blank is selected when Selective filling metal is sn-bi alloy, because sn-bi alloy fusing point only has 58 DEG C-160 DEG C, has good mobility after heat fusing, and the physical characteristic of part blank can not be caused to change.
Because the example of the part blank adopting the cast of low melting point tin bismuth alloy fixing is few, practical experience is fewer, and through repeatedly proportioning test, the filling low-melting alloy formula rate of this part blank is as follows:
Antimony (Sb) 9%; Plumbous (Pb) 28.5%; Bismuth (Bi) 48%; Tin (Sn) 14.5%; Fusing point 120 DEG C.
Because cast alloy, originally thin-wall case has been linked to be one, and the rigidity of part blank strengthens widely.In this case processing parts blank just give no thought to part processing after resilience and Stress Release.
Utilize the process area location of casting out that part blank is put into fraise jig, pressing plate pressing process platform top, milling is carried out to the surface that the needs of part blank are processed, because there has been process area location, the filling of low-melting alloy metal has been carried out in part blank inside simultaneously, milling process becomes brisk, and working (machining) efficiency and piece surface integrality improve.By improving, each feed cutting depth brings up to more than 2mm by 0.1mm; Cutting speed brought up to 30mm/ minute by 5mm/ minute.Qualitative leap has been there is from working (machining) efficiency.Dimensionally stable in crudy, originally added and has man-hour the knife mark road that shakes no longer to exist, and existing Part Surface Roughness after processing reaches or close to 1.6 μm.
three, the part processing of environmental protection, low cost is realized
Antimony (Sb); Plumbous (Pb); Bismuth (Bi); Tin (Sn) fusing point is low, does not have toxic gas to discharge after heating for dissolving, without the need to increasing dust discharge retracting device in addition; After process finishing, the low-melting alloy of fabricated part and filling is put into 150 DEG C of dry pots in the lump to heat, in dry pot, liquid state is dissolved into after low-melting alloy heating, and the material of fabricated part own is high temperature alloy, under 150 DEG C of environment, interior tissue and external stress all can not change, after casting metals dissolves completely, just can obtain qualified fabricated part.And the low-melting alloy after dissolving can carry out subsequent parts processing, achieve low cost operation, be convenient to batch production.
