1st, screw rod 4 and nut and packing ring 14 compress blank, and pressure-pad-force size is adjustable, form flanging, the micro- backhaul of upper table, remove four
Deng stock, flanging terminates, and product 8 just pulls into shape by drawing punch 3；Then drawing punch 3 is replaced by forming terrace die 11, simultaneously
Die cavity is added to shape rubber 12 in product 8, by adjusting the different structure size of formed rubber 12, with formed rubber 12
Superelastic characteristics, the characteristic make blank prolonged expansion from inside to outside, until being bonded completely with shape in cavity plate component 6, complete product 8
Shaping, product 8 is set finally to meet physical dimension requirement；For last cope plate 2 in press return, taking-up divides mould locating rod 7, upper work
Make platform backhaul, lifting rope 13 is by the drawing cavity plate a 6.1 in blank holder 5, cavity plate component 6, drawing cavity plate b 6.2 and cavity plate component 6
In drawing cavity plate c 6.3, die plate insert d 6.4 and die plate insert e6.5 separated along die joint, product 8 is ejected by push rod 9.
Described die joint choose in product 8 it is maximum it is cylindrical on.
Described product 8 uses monolithic molding structure.
Using the beneficial effect of above-mentioned technical proposal:
The present invention changes original mould structure thinking, and blank body is separated with die main body, while cavity plate component is using split type
Structure, not only beneficial to product discharging but also it is optimised the anufacturability of mould parts, so as to reduce die manufacturing cost, contracting
Short die manufacturing cycle and Making mold precision is improved, while improve product reliability, comprehensive mechanical property, service life, anti-
Pressure energy power and resistance to corrosion, eliminate safe hidden trouble.

Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.But not as any limitation of the invention according to
According to.
As Figure 1-3, it is a kind of to be used for circular cone involucrum shaping dies, it is main including skewback 1, cope plate 2, drawing punch 3,
Screw rod 4, blank holder 5, cavity plate component 6, divide mould locating rod 7, push rod 9, lower template 10, forming terrace die 11, formed rubber 12, lifting rope
13 and nut and packing ring 14；Wherein cavity plate component 6 uses block insert type structure, optimizes the manufacturability of mould structure part, cavity plate component 6
It is made up of drawing cavity plate a 6.1, drawing cavity plate b 6.2, drawing cavity plate c 6.3, die plate insert d 6.4 and die plate insert e6.5.
The blank holder 5 is arranged at the lower section of cope plate 2, therebetween provided with lifting rope 13；The cavity plate component 6 is arranged under blank holder 5
Side, its side, which is provided with, divides mould locating rod 7；The top of screw rod 4 is fixed by nut and packing ring 14 by blank holder 5, and bottom is provided with
Skewback 1；The formed rubber 12 is arranged in the cavity plate component 6 of the lower section of forming terrace die 11.
The blank body of the present invention is both mould entirety inalienable part with mould bases and cavity plate component, is mutually solely again
Vertical movement parts.
A kind of manufacturing process of circular cone involucrum, the blank of product 8 is positioned in the positioning ring groove of cavity plate component 6 first, four
It is suspended in equipment upper table T-slot, reaches pressure-pad-force on blank holder 5 under press effect, then pass through skewback Deng stock
1st, screw rod 4 and nut and packing ring 14 compress blank, and pressure-pad-force size is adjustable, form flanging, the micro- backhaul of upper table, remove four
Deng stock, flanging terminates, and product 8 just pulls into shape by drawing punch 3；Then drawing punch 3 is replaced by forming terrace die 11, simultaneously
Die cavity is added to shape rubber 12 in product 8, by adjusting the different structure size of formed rubber 12, with formed rubber 12
Superelastic characteristics, the characteristic make blank prolonged expansion from inside to outside, until being bonded completely with shape in cavity plate component 6, complete product 8
Shaping, product 8 is set finally to meet physical dimension requirement；For last cope plate 2 in press return, taking-up divides mould locating rod 7, upper work
Make platform backhaul, lifting rope 13 is by the drawing cavity plate a 6.1 in blank holder 5, cavity plate component 6, drawing cavity plate b 6.2 and cavity plate component 6
In drawing cavity plate c 6.3, die plate insert d 6.4 and die plate insert e6.5 separated along die joint, product 8 is ejected by push rod 9.
Described die joint choose in product 8 it is maximum it is cylindrical on.
Described product 8 uses monolithic molding structure.
The present invention improves the reliability of product 8 to ensure the quality of product 8, it is ensured that safety and easy to operate and reduction
Die manufacturing cost, just drawing-die and finishing die common die part, edge pressing structure part and the part of cavity plate component 6 are taken, works as production
After the just drawing of product 8, drawing punch 3 is replaced by forming terrace die 11, die cavity is added to shape rubber 12 in product 8, passes through adjustment
The different structure size of formed rubber 12, product 8 is set finally to meet physical dimension requirement.Another difficult point that product 8 shapes is into
The cooperation of the structure of shape punch-pin 11 and geomery and cavity plate component 6 is closed, and should ventilate prevents formed rubber 12 in pressure again
Effect is lower outwards to extend, at the same must make again product 8 in formation metal flow naturally, avoid product shaping because resistance is excessive and
Drawing crack.
The present invention is applied to the baroque deep cooling stamping parts of large thin-wall waist-drum-shaped.
