Abstract
The present invention is a kind of new sheet part forming method that utilizes elastic fluid, and it is specially adapted to the drawing and moulding of large complicated sheet part (as the covering of automobile, tractor, the housing of aircraft, rocket, spacecraft).
This method can make die manufacturing cycle shorten, and cost reduces.
Description
The present invention is a kind of new sheet metal part forming method.Be applicable to the particularly large-scale complex-shaped part forming of sheet part that 2MM is following.
The conventional method of sheet part moulding is that punching block is shaped.Particularly the steel die manufacturing cycle is long, cost is high owing to punching block, and a kind of new manufacturing process is arranged at present, and the die of promptly using elastic fluid (as rubber, plastics etc.) to make monoblock elastomer and metal appearance frame composition replaces steel die moulding part in addition.But this method is difficult in large complicated part forming because following shortcoming is arranged promote: (one) elastomer price height, consumption is big, can not be general.(2) monoblock elastomer (comprising sandwich construction) itself can not flow, and can only produce the purpose that distortion reaches shaping under immense pressure.So the tonnage of press device is much higher than punching block.If the part shape complexity then must be given and be poured into given shape, can be shaped.(3) in forming process, huge pressure major part is converted into heat energy and accumulates in the elastomer, and the radiating surface of itself is again little, for improving its life-span, can only use on hydraulic press at a slow speed, so efficient is low.(4) because this elastomeric resilient modulus is big, and imperfection sensitivity is big, therefore requiring has surface quality preferably, in case profile cracks necessary reconditioning.(5) formation of parts is wished the existing higher capacity of elastomer, and deformation performance is preferably arranged again.And the elastomeric bearing capacity height of high rigidity but deformation performance is poor; Durometer elastomer then deformation performance is good, but bearing capacity is low.This contradiction can't solve.
The purpose of this invention is to provide a kind of new manufacturing process, it can address the above problem preferably.Its feature is with making the elastomer that granular elastomer replaces monoblock.
The present invention is achieved in that existing is that example illustrates with the drawing die.In metal appearance frame, put into granular elastomer and form die (counterdie), place plate to be processed on it, under the pressure-pad-force effect, form an enclosed cavity.When punch (patrix) descended, the graininess elastomer at first produce to flow under pressure, after eliminate substantially in the space between elastomer, produced distortion again, and plate is close on the punch and moulding.
The present invention is applicable to and draws, also can be used for to bend and expansion forming (must carry out in enclosed cavity).
The present invention also has following characteristics except the advantage with former elastic fluid manufacturing process:
(1) the elastomeric material consumption is few and can be general, so Master Cost is low.(2) few because of elastomer particles good fluidity and consumption during moulding, can make the press device tonnage descend 50%.(3) even elastomer particles cracks, in use also only particle is diminished and can not influence shaping, can save profile reconditioning operation.(4) the elastomer particles surface area is elastomeric more much bigger than monoblock, adds in forming process corresponding generation discharge of the air in the particle gap and suction action and can improve heat-sinking capability.So can select the higher forcing press of speed for use, raise the efficiency.(5) can select for use the high rigidity elastomeric material to comprise and strengthen elastomeric material, so both improve the bearing capacity of material, not influence flowability again with metal (as aluminium) fiber or powder or nonmetal (as carbon, boron) etc.(6) owing to have the gap between elastomer particles, can adopt topping up at need or sneak into solid lubricant methods such as (as molybdenum bisuphide), improve molding condition, improve cooling effect in shaping.
This elastomer particles can be used rubber, plastics manufacturings such as (as polyurethane).Shape is good with the garden sphere, considers easily manufacturedly, also can make garden cylindricality or other shape.Granular size can be determined according to the size and the complexity of part, be principle with the minimum die cavity that can be full of easily in the complex-shaped surface mould.Recommend to use size: 5～30MM diameter (garden sphere).
