The specific embodiment

Below in conjunction with accompanying drawing technical solutions of the utility model are further described.

A kind of contour combined metal material cast pattern of cutting apart, it is constituted by the contour cut piece more than one deck, wherein two upper and lower corresponding positions of cut piece combinatorial surface are provided with protruding, the recessed combining structure of modularization of the assembly that can coincide, and corresponding position is provided with screw on protuberance and recess, and putting into each cut piece of the fastening combination of screw with bolt is the monoblock cast apperance.As shown in Figure 5, in this example be three layers of contour cut piece combination.

The described contour combined type cast pattern of cutting apart, it is constituted by three layers of contour cut piece, also can be constituted by two-layer or the contour cut piece of multilayer; Contour dividing layer higher primary school is long in cutter.

Specific implementation process is:

(1) geological information of cast pattern and manufacturing attribute are imported to 3-D graphic Interactive CAD of Hydro-machine design system by data-interface, or direct physical model at this system creation cast pattern; This example imports with the CAXAME system, and also available other has the computer software of this function to import.

(2) determine contour dividing layer high parameter H _MaxBe less than or equal to the long L of cutter.Generally determine the diameter D of milling cutter according to the minimum recess radius R min of complex object cast pattern feature dimension, cutter footpath D equals 2Rmin, and the long L of cutter is 5D or 10Rmin.

(3) complex object contour cut apart design

Under 3-D graphic Interactive CAD of Hydro-machine design environment, it is long in cutter to press actual layer higher primary school, the physical model of cast pattern is divided into the physical model of one group of cut piece more than one deck.H is the height of cast pattern, equals each floor height sum.As shown in Figure 1.

This example is cut apart design in the CAXAME system, when Fig. 1 is the integral body cutting of cast pattern example, utilize existing cutting technology P point can not realize the schematic diagram that cuts, Fig. 2 is that the contour dividing body bottom P point of the utility model cast pattern example can be realized the schematic diagram that cuts.1 is cutter hub among Fig. 1, and 2 is cutter, and 3 is middle cut piece, and 4 is contour divisional plane, and the R position is minimum recess radius R min.

This example is divided into three layers of contour level to cast pattern as can be seen from Figure 1, as can be seen from Figure 1, because cutter hub 1 is interfered, cutter 2 can not cut the p point position of cast pattern, and in Fig. 2 as can be seen, after contour cutting apart, cutter 2 can be easy to cut the p point position of cast pattern and the cutting of R least part, and do not need to change cutter and Digit Control Machine Tool equipment, Milling Process easily, simply.Therefore, contour individual casting apperance is just to finish the processing of the cast pattern of complex object after the layering, and suitable high-speed numeric control milling, improves work efficiency and precision greatly.

(4) blank of cut piece preparation

Machinable material is made and the corresponding plate shape of cut piece profile, and each is to leaving surplus; Also can process other nonmetallic materials.As the cut piece to be processed 9 among Fig. 3.

(5) cut piece combinatorial surface numerical control cutting processing

Slabbing is carried out in bottom surface to cut piece, and it is concave station processing that the bottom surface combining structure is carried out the groove milling, to the hole drill centre bore of combining structure or make screwed hole.Be processed into the modularization concave, convex combining structure of the assembly that can coincide.

(6) combination of complex object

The cut piece that processes is cleaned, assembled, recover the integrality of cast pattern, can apply bond at divisional plane as required, to improve the intensity and the air-tightness of faying face, and with screw fastening cut piece in screwed hole, the processing of cast pattern combination is finished.

Fig. 3 is the utility model example cut piece installation way schematic diagram when processing on Digit Control Machine Tool.

Fig. 4 is the front view after the contour division processing combination of the utility model example cast pattern, and Fig. 5 is the A-A profile after the combination of the utility model example cast pattern division processing.10 is the upper strata cut piece among Fig. 5, and 3 is the intermediate layer cut piece, 5 lower floors (bottom) cut piece, 11 is bolt, screw thread joint portion, 12 for bond be metal viscose glue class.

The utility model is fit to manufacturing and designing and digital control processing of part, is fit to the design and the processing of other similar complex object metal works equally.
