Description
Technical field
The present invention relates to metal precision forging field, particularly a kind of mould of fluted disc forging.
Background technology
Refer to Fig. 1, its structural representation that is a kind of fluted disc. Refer to Fig. 2, it is made in prior artMake the structural representation of the drift of fluted disc in Fig. 1. Refer to Fig. 3, it is tooth in shop drawings 1 in prior artThe structural representation of the die of dish. As shown in Figure 1, the bottom of described fluted disc 200 has the first cannelure 101.
As shown in Figure 1, according to the model of this fluted disc of structure of described fluted disc 100, existing drift 200 is wholeBody drift, in the process punching of extrusion molding, because larger normal direction extruding force is born at the A place of drift 200,Cause the A place of drift 200 easily to occur fracture, the life-span is shorter, and also difficult processing of drift 200, andAnd drift 200 bottom have an arc turning 201, turning 201 makes its discontinuity herein, produceAn active force obliquely, thus drift 200 is easily ruptured.
Refer to Fig. 3, described die comprises matrix cavity 301 and the second cannelure 302. Of the prior artDie 300 is overall structure, makes bottom first cannelure 101 of fluted disc 100 be difficult for processing, and shouldThe first cannelure 101 is the dead angle areas that grind, and existing die is prone to the forging angular defect of collapsing aborning,It is also extremely difficult repairing. In the time that blank is come in, make the second cannelure 302 places of die 300Air cannot be discharged, and causes thereby blank cannot be filled up the angle of collapsing.
Therefore, be necessary to propose a kind of improved technical scheme and solve the problems referred to above.
Summary of the invention

Detailed description of the invention
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing andThe present invention is further detailed explanation for detailed description of the invention.
Alleged " embodiment " or " embodiment " refer to and can be contained at least one reality of the present invention hereinSpecial characteristic, structure or characteristic in existing mode. Different local in this manual occur " a realityExecute in example " not all refer to same embodiment, neither be independent or optionally mutual with other embodimentThe embodiment repelling.
Refer to Fig. 4 and Fig. 5, the structural representation that Fig. 4 is patrix of the present invention; Fig. 5 is die of the present inventionStructural representation. As shown in Fig. 4 to 5, described mould comprises patrix 400 and die 500.
Please continue to refer to Fig. 4. Described patrix 400 comprises fairlead 401, is positioned at the pressure of fairlead 401 inner sidesPower piece 402 and annular punch 403 and be positioned at the fill block 404 of described annular punch 403 inner sides, described pressurePiece 402 is positioned at the top of described annular punch 403 and fill block 404. Described fairlead 401, pressure block 402,Annular punch 403 and fill block 404 coaxially arrange. Described fairlead 401 play the guiding role, and then has ensuredThe concentricity of circle product external and endoporus, described pressure block 402 and fill block 404 are compensation fill block, protection is supportedAnnular punch 403 and fairlead 401. Solid punch of the prior art is become split punch structure by the present invention,This structure is processed simply, is easy to assembling, and the life-span is higher, has well met need of production. Described annularThe head of drift has arcuate structure.
Please continue to refer to Fig. 5. Described die 500 comprises internal mold 501 and core rod 502, described internal mold 501 HesCore rod 502 forms matrix cavity 503. The edge of the top end face of described core rod 502 has core rod cannelure 505.Refer to Fig. 6, it is the structural representation of core rod in Fig. 5. From the core rod annular of described core rod 502 top end facesGroove 505 is interior is extended with air discharge duct 504 to core rod 502 bottoms, and described air discharge duct 504 is from described core rod 502Top to bottom is communicated with. In this embodiment, the quantity of described air discharge duct 504 is multiple. When matrix cavity 503In blank (not shown) while being extruded, the air in described core rod cannelure 505 can pass through air discharge duct 504Directly discharge outside core rod 502, and then make blank fill up whole core rod cannelure 505, ensured that forging can notCause the problem at the angle of collapsing. In other embodiments, the quantity of described air discharge duct 504 is one, this air discharge duct504 shape is similar to the shape of described core rod 502 sidewalls. The mode that die of the present invention adopts core rod to be press-fitted,On the annular sidewall of core rod, offer multiple air discharge ducts that are connected to core rod bottom from core rod cannelure, no simultaneouslyOnly monomer is easy to process, and has solved the problem of profile of tooth bottom processing difficulties.
Refer to Fig. 7, its assembling schematic diagram that is mould of the present invention. The process of forging fluted disc forging of the present inventionAs follows: in the time that the blank in matrix cavity 503 is forged, first blank is put into matrix cavity 503,Described patrix moves downward, and described annular punch 403 and fill block 404 are subject to the effect of described pressure block 402Move downward, fairlead 401 also moves downward simultaneously, and meanwhile, described core rod 502 moves upward, described inIt is needed fluted disc forging 506 that annular punch 403 is carried out extrusion modling to the blank in matrix cavity 503, squeezesPressure completes.
Mould of the present invention adopts the mode of Split type structure, and patrix is divided into several parts, respectively group after processingLoad use, so not only make the various piece of patrix more be of value to processing, and put in productionEffective, not only can produce qualified product, and well solve the drift longevity in prior artOrder shorter problem; The structure that die of the present invention is press-fitted by core rod, the processing that has alleviated greatly mouldDifficulty, simultaneously well solved the problem that is prone to the angle of collapsing in extrusion process, extended greatly mouldLife-span.
Above-mentioned explanation has fully disclosed the specific embodiment of the present invention. It is pointed out that and be familiar with being somebody's turn to doAny change that the technical staff in field does the specific embodiment of the present invention does not all depart from power of the present inventionThe scope of profit claim. Correspondingly, the scope of claim of the present invention is also not limited only to aforementioned toolBody embodiment.
