The shaping dies that has flanging and hermetically-sealed construction of the present utility model, its preferable specific embodiment is, comprise upper die body that is fixed on the upper bolster and the lower mold body that is fixed on the die shoe, the periphery of described upper die body profile is provided with sealing ring and blank holder, and described upper die body and lower mold body are respectively equipped with gas passage.
Described sealing ring and described upper die body are fixed as one, and described blank holder flexibly connects by connecting rod and described upper die body.Fixedly connected with described blank holder in the lower end that specifically can be described connecting rod, the upper end of described connecting rod and described upper die body flexibly connect.
The lower surface of described upper die body is a profile, and described sealing ring is arranged on the periphery of described profile, and described blank holder is located at the periphery of described sealing ring.
The profile of described upper die body and the profile of described lower mold body have at least one to be forming surface;
When the profile of upper die body was forming surface, the gas passage on the lower mold body was an air inlet pipe, and the gas passage on the upper die body is an escape pipe;
When the profile of lower mold body was forming surface, the gas passage on the upper die body was an air inlet pipe, and the gas passage on the lower mold body is an escape pipe.
The existing flanging of the utility model has sealing function again, collect flanging with sealing function in, two kinds of technologies of punching press and inflatable are combined, realize integrate innovations combined shaping structure.
In the punching press stage, upper die body is descending, and blank holder compresses sheet material; When lower mold body went downwards to sealing ring and compresses sheet material, punching press finished, and inflatable begins, and sealing ring provides seal cavity for inflatable, guaranteed gas expansion forming.Be implemented in the mould structure and finish punching press and gas expansion forming continuously,, avoided more mold exchange of different process both advantages, improve element precision, reduced die cost, significantly shortened curring time, improve production efficiency greatly, guaranteed to produce in enormous quantities needs.
The unique design of the utility model flanging and hermetically-sealed construction makes that punch profile and die profile can be as forming faces.
The utility model is specially adapted to the quick superplasticforming of aluminium alloy automobile covering, also is applicable to the quick superplasticforming of coverings such as train, aircraft, steamer, also is applicable to the punching press and the inflatable combined shaping of other material.
Specific embodiment:
As shown in Figure 1, the utility model is made up of upper die and lower die two parts, and patrix is provided with upper bolster 1, upper die body 2, sealing ring 3, patrix heating collar and hangs coil support 4, air inlet pipe 5, patrix heating collar outward and hang circle 6, patrix heating collar 7, muff 8, connecting rod 9, spring 10, blank holder 11 outward; Counterdie is provided with die shoe 12, lower mold body 13, escape pipe 14, counterdie heating collar 15.
Upper die body 2 is fixed on the upper bolster 1, sealing ring 3 designs are in upper die body 2 bottoms, with upper die body 2 be one, the patrix heating collar hangs coil support 4 outward and the patrix heating collar hangs the outer ring that circle 6 is fixed on patrix heating collar 7 upper die body 2 outward, one end of connecting rod 9 is connected with blank holder 11, and the other end and upper die body flexibly connect, and muff 8 is fixed on the bottom of patrix heating collar 7, the effect of heating collar is that mould up and down is heated to specified temp, and die body and die cavity are maintained under the isothermy.Lower mold body 13 is fixed on the die shoe 12, and counterdie heating collar 15 is enclosed within the outer ring of lower mold body 13, and counterdie is provided with escape pipe 14, and the groove of counterdie profile is provided with a plurality of through holes and links to each other with escape pipe 14.
Drop stamping and superplastic gas-bulging all are to carry out under specific temperature conditions, and actual temp is selected according to the characteristic of selected aluminum alloy materials.
As shown in Figure 1, before the moulding, patrix heating collar 7 and counterdie heating collar 15 be up and down die body heating respectively, reach forming temperature after, aluminum alloy plate materials 16 is placed on the lower mold body 13.
As shown in Figure 2, patrix moves down, drivening rod 9 and blank holder 11 move down and push down aluminum alloy plate materials 16, be with a spring 10 on each connecting rod 9 respectively, when hot press-formed, along with moving of patrix, spring 10 compressions increase gradually, and the pressure of 11 pairs of aluminum alloy plate materials 16 of blank holder also just increases gradually.
As shown in Figure 3, patrix continues to move down, and sheet material begins distortion, and the sealing ring 3 on the patrix arrives the precalculated position, contacts with the aluminum alloy plate materials 16 of counterdie, and drop stamping finishes.Under the effect of die pressure up and down, sealing ring compresses aluminum alloy plate materials 16, forms the superplastic gas-bulging needed seal cavity of being made up of patrix and aluminum alloy plate materials 16 that is shaped.
As shown in Figure 4, next step begins gas expansion forming, feed gas from the air inlet pipe 5 of patrix, aluminum alloy plate materials 16 is distortion gradually under the effect of gas pressure, the air at the aluminum alloy plate materials back side is discharged by counterdie escape pipe 14, reduces and pastes the mould resistance, and sheet material is fitted with the profile of lower mold body 13 gradually under the effect of gas pressure, after the pressurize of a period of time, gas expansion forming finishes.
When the patrix profile was forming face, escape pipe also can be used as air inlet pipe, and air inlet pipe also can be used as escape pipe, carried out drop stamping and superplastic gas-bulging equally and was shaped.
The utility model realizes respectively that in same mould drop stamping and superplastic gas-bulging are shaped, and has avoided more mold exchange of different process, has improved element precision, reduced die cost, significantly shorten curring time, improved production efficiency greatly, guaranteed to produce in enormous quantities needs.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
