Abstract
The present invention is the finished product embedded set arbor made from mouldless shaping, and the intensity of finished product and rigidity are improved, and has opened up this The Application of Technology scope.Technology of the present invention is to be reserved with the finished product data input computer of embedding arbor groove, to obtain three-dimensional digital model.During shaping, computer control is successively sprawled particulate material with lift height and is piled up, and spraying adhesive in the X-Y scheme entity scope on every layer of particulate material finishes until being shaped.Remove the particulate material of not spraying binding agent, promptly obtain fluted finished product.Arbor is inserted in the groove, use from hard inserts and fill up and repair and accuse and finish.This features simple and practical process, for the yielding of mouldless shaping manufacturing and the finished product that easily breaks, as big and approach, the thin and finished product grown, this difficult problem is cracked behind the embedding arbor.
Description
Technical field
The present invention relates to the mouldless shaping manufacturing technology, particularly can improve the non-mold forming technique of product intensity and the finished product that makes with this technology.
Background technology
Existing a kind of non-mold forming technique is the data input computer with finished product, by the computer control laying device particulate material is spread on the workbench with lift height, spray equipment spraying adhesive accurately in the scope of the finished product cross section of this layer figure, the workbench height of face that sends behind is finished a working cycles then.Repeat stone one spray and move down, finish until being shaped except that a workbench.Remove the discrete particles material that does not spray binding agent, promptly obtain bonded dose of formed finished product of adhesive solidification of a particulate material.Finished product can be the entity of product, also can be the casting mold or the core of product.The mouldless shaping manufacturing technology has been saved traditional molding operation, has advantage such as save time, laborsaving and accurate, is enterprise's favor.
The finished product that above-mentioned mouldless shaping makes is that the discrete particles material forms through the binding agent adhesive solidification, and its intensity is inferior slightly, and particularly big and thin and thin and long finished product is yielding or break and scrap because of its strength and stiffness deficiency, has hindered applying of this technology.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, propose a kind of new technology of the mouldless shaping that improves product intensity and the new finished product that makes thereof.
Technical scheme of the present invention is: a kind of non-mold forming technique that improves product intensity, be with finished product data input computer, obtain the three-dimensional digital model of finished product, computer carries out layering according to certain bed thickness, obtain the X-Y scheme of each layer cross section, during shaping, by computer control particulate material is successively sprawled with lift height and to be stacked on the workbench, computer is according to spraying adhesive accurately in the X-Y scheme entity scope of this layer on every layer of particulate material of completing, obtain a 3D solid behind all layer bonding finishing, remove the particulate material of not spraying binding agent and just obtain a finished product, it is characterized in that: in the finished product data, be reserved with groove, make that X-Y scheme when being shaped is corresponding to be reserved with breach or every ditch, after finishing, shaping obtains fluted finished product, in groove, put into arbor then, with filling up groove, arbor and finished product are combined into one again from hard inserts.
Finished product with described technology makes is characterized in that: arbor arranged in that the weak part of finished product is embedding.
Features simple and practical process of the present invention has improved the intensity and the rigidity of finished product behind finished product embedded set arbor, reach goal of the invention.

The specific embodiment
Now be further described in conjunction with the accompanying drawings.
Fig. 1 and Fig. 3 add three-dimensional digital model 1 schematic diagram of putting vertical and lateral trench 2, Fig. 2 and Fig. 4 are the layer stack forming process, fluted aspect is groove breach 3 to be arranged or every the X-Y scheme of ditch 4, be shaped finish after i.e. reduction obtain the finished product entity of groove 2.
Fig. 5 is the exhaust pipe of engine core that makes with existing non-mold forming technique, all is that particulate material forms through the binding agent adhesive solidification.It is thin and grow, because of intensity and rigidity deficiency, yielding with break, product qualified rate is not high.
Fig. 6 is the vertical profile parallax stereogram of the embodiment of the invention 1 exhaust pipe of engine core, at core body 5 embedded set arbors 6.Arbor 6 improves core integral intensity and rigidity greatly, has opened up mouldless shaping The Application of Technology scope.
Fig. 7 illustrates forming technology process embodiment of the present invention: laying device is after evenly spreading one deck particulate material on the workbench 7, spray equipment is pressed only spraying adhesive accurately in the entity X-Y scheme scope of this aspect of computer instruction, workbench 7 height of face that sends behind then, stone one spraying is again piled up layer by layer until being shaped and is finished.Remove in the groove and the discrete particles material 8 of the core external space, promptly obtain being sprayed with the core body 5 that the particulate material adhesive solidification of binding agent forms, have groove and groove upper end uncovered in it.Then arbor 6 is placed groove central authorities and, arbor 6 and core body 5 are united two into one with filling up groove and compacting from hard inserts 9.Finishing touch, polishing groove upper port are finished the manufacture craft overall process.
Fig. 9 is the water pump vane core, and is big and approach, in the space 10 of water pump blade mould is arranged, undercapacity, yielding with break.The present invention is the embedding arc arbor 11 similar to blade shape between blade mould space 10, its manufacture craft and exhaust pipe of engine core identical.Arbor 11 improves the intensity of water pump vane core, has cracked the difficult problem that the mouldless shaping technology is applied.
When other manufactures a finished product with the mouldless shaping technology, all can be at the weak part of finished product by the embedding arbor of process of the present invention.
The material of arbor is a mild steel, also can be cylinder iron.Arbor must be through annealing in process, to reduce internal stress.The shape of arbor and size are decided according to the concrete structure of finished product.
Groove width is 3～5 times of arbor width, widely easily makes finished product distortion, and narrow that arbor is combined with the finished product body is not tight, the intensity of reduction finished product.Gash depth is 3～5 times of arbor height, and arbor is positioned at the middle position of groove, can guarantee to improve the effect of product intensity.
From the composition of hard inserts is to be radix with 100% particulate material, adds the mixture of 1～2% binding agent and 0.3～1.2% curing agent, also can be furan resin-sand, phenol resin sand, PEP SET resin sand, water-glass sand and gypsum etc.
