Different according to the workpiece shapes of institute's die forging, multi-ram forging has vertical parting and horizontal parting two kinds usually.Vertical direction valve with flange as shown in Figure 1, if employing horizontal parting, need three drifts, the equipment of three drifts is not also installed in current domestic and international existing multi-ram forging simultaneously, if design the multi-cored forging press of three drifts action simultaneously, that equipment will be very complicated.During horizontal parting, if die joint is located at A-A face, after die forging, workpiece cannot take out die cavity.Multi-ram forging hydraulic press is in the horizontal direction owing to only there being two horizontal cylinder, and will realize matched moulds in other words just cannot punching, must design mold closing mechanism in addition.
Summary of the invention
In order to overcome Problems existing in prior art, the present invention proposes a kind ofly to use multinomial die forging method to the method for the vertical direction valve with flange class part that is shaped.
To achieve these goals, the present invention proposes the vertical split cast mounting of a kind of multinomial die forging, comprises left mould, right mould, upper punch, horizontal punch, upper matched moulds cover, lower matched moulds cover, upper padding plate, sliding support, lower bolster, cylinder and air cylinder support.Together with described upper matched moulds cover is connected by screw with upper padding plate, upper surface and the upper matched moulds cover of sliding support link together, cylinder and lower matched moulds cover link together, lower matched moulds cover is linked together by screw and left mould, right mould is fixed by bolts on workbench, and locates on the table with key.When operating, cylinder drives left mould and right mould matched moulds by lower matched moulds cover, after matched moulds, valve body blank is put into die cavity.Multinomial stamp forging hydraulic press drive upper padding plate, upper matched moulds cover and sliding support descending, together with left mould to be firmly fixed with right mould by inclined-plane by upper matched moulds cover, sliding support is played a supporting role between right mould and lower matched moulds cover.At this moment in the middle of multinomial drop press, perforation cylinder drives upper punch descending, bores a hole, then to valve body, multinomial stamp forging hydraulic press two horizontal cylinder drive two horizontal punch respectively, punching is carried out to valve body horizontal direction, so far, completes the multinomial die-forging forming to valve body.
Realizing above-mentioned technical scheme is: the vertical direction matched moulds of the vertical split cast mounting of multinomial die forging, when multinomial die forging, and first cylinder right-hand member gas port exhaust, the air inlet of left end gas port, drive left mold movement by lower matched moulds cover, and move to and be close to right mould, realize matched moulds.Put into blank after matched moulds, press move sill bolt dynamic upper matched moulds cover and sliding support descending, under it acts on, together with left mould to be put together on right mould by inclined-plane by upper matched moulds cover securely.Played a supporting role between right mould and lower matched moulds overlap by sliding support.Now, the drift of vertical direction carries out punching, and finally, two drifts of horizontal direction carry out punching, complete the multinomial die forging to part.
The vertical split cast mounting beneficial effect of the multinomial die forging of the present invention is mainly manifested in: vertical direction mold closing mechanism can realize zero clearance between the mould of left and right, does not forge overlap during die forging, saves subsequent mechanical processing, reduces cost of parts.In addition, conventional die forging can only forge the profile of workpiece, and inner hole all needs subsequent mechanical to process, and machining amount is very large.The multinomial die forging forging geomery that this method forges is closer to part, and stock utilization is high, and machining amount is few; Forging streamline is complete, and stress corrosion resistant is good, and fatigue strength is high.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
Please refer to Fig. 4 and Fig. 5, Fig. 4 is multinomial die forging vertical split cast mounting structure schematic front view, and Fig. 5 is that schematic diagram is looked on a multinomial die forging vertical split cast mounting structure left side, is provided with mold closing mechanism and three drifts of cylinder drive in vertical direction.The vertical split cast mounting of multinomial die forging is primarily of compositions such as left mould 1, right mould 8, upper punch 3, horizontal punch 14, upper matched moulds cover 5, lower matched moulds cover 9, upper padding plate 4, sliding support 7, key 11, lower bolster 12, cylinder 10, air cylinder support 13 and attachment screws 6.Cylinder 10 and lower matched moulds cover 9 link together, and lower matched moulds cover 9 is linked together by screw and left mould 1, and right mould 8 is fixed by bolts on workbench, and locates on the table with key 11.When operating, cylinder 10 drives left mould 1 and right mould 8 matched moulds by lower matched moulds cover 9, after matched moulds, valve body blank is put into die cavity.Because upper matched moulds cover 5 and upper padding plate 4 are linked together by screw 6, the upper surface of sliding support 7 and upper matched moulds cover 5 link together, at this moment multinomial stamp forging hydraulic press drive upper padding plate 4, upper matched moulds cover 5 and sliding support 7 are descending, together with left mould 1 to be firmly fixed with right mould 8 by inclined-plane by upper matched moulds cover 5, sliding support 7 is played a supporting role between right mould 8 and lower matched moulds cover 9.At this moment in the middle of multinomial stamp forging hydraulic press, perforation cylinder drives upper punch 3 descending, bores a hole, then to valve body, multinomial drop press two horizontal cylinder drive two horizontal punch 14 respectively, punching is carried out to valve body horizontal direction, so far, completes the multinomial die-forging forming to valve body.
Used conventional die forging in the past, and wanted to make blank be full of whole die cavity, and needed very large Die Forging during die forging, so just need large-tonnage drop press equipment.This kind of part of conventional die forging time image vertical direction valve with flange, three holes of vertical direction and horizontal direction can not be forged out, often need subsequent mechanical to process; In addition, owing to usually using horizontal parting, make to there is gap between upper/lower die, by producing very large forging overlap during die forging, both taking machining period like this, turn improving the manufacturing cost of part.
Contrast conventional die forging and have very large difference, due to multi-ram forging valve with flange class part, die joint adopts vertical direction, do not need very large-tonnage drop press, just blank can be filled whole die cavity during die forging.Vertical direction is directly rushed out respectively by vertical drift and horizontal punch with three holes of horizontal direction, which saves subsequent mechanical processing; In addition, there is not gap, therefore do not forge overlap when die forging between the left mould of vertical parting and right mould, the forging of this kind of multinomial die forging method manufacture saves follow-up a large amount of machining, reduces cost of parts.This new technology mould structure is simple, easy to loading and unloading, is convenient to tissue batch production, therefore can obtains higher economic benefit.
