Description

Numerical control multiple spot dieless hydro-bulging system
Technical field:
The present invention relates to a kind of numerical control multiple spot dieless hydro-bulging system.
Background technology:
Along with the development of society, complicated hyperbolic sheet metal is in aircraft, boats and ships, express locomotive, automobile or even building etc. In all conglomeraties, more and more used.People not only require that the double-curved shapes shaped is different, require that again it shapes essence Degree is high, production efficiency is high, surface quality is good, uniformity.Metal sheet forming technique is just proposed and chooses greatly by this War.
In tradition plate manufacturing process, hand finishing method is owing to production efficiency is low, machining accuracy is low, it is large quantities of to be not suitable for Amount produces, and does not occupies leading position in sheet forming.Die forming method production efficiency is high, the precision of workpiece is high, suitable Close and produce in enormous quantities, the most always in occupation of leading position.But shortcoming is that the mould design and manufacture cycle is long, maintenance cost is high, Often shaping a part and need multiple moulds, cause new product development cycle long, cost is high, and lacks flexibility, and product is slightly Make to change rear mold to need to redesign replacing.
Therefore, the sheet forming technology of some new shapes is arisen at the historic moment, such as: contour peening, laser forming, water jet become without mould Shape technology, digitizing inspection, non-mould multi-point forming etc..But the sheet forming technology of these several new shapes there is also some Shortcomings and limitations, the limitation of contour peening is spherical deformation trend, limited deformation, restrictive condition is harsh, influence factor is numerous Many etc.;The shortcoming of laser forming is that cost is high, it is not easy to control;Water jet freeform fabrication also needs to the most perfect, Actual application there is also a lot of problem;Digitizing inspection needs to make mould, and processing cost is high, the cycle is long, surface matter The shortcomings such as amount difference;Compared with front several forming techniques, non-mould multi-point forming technology has a lot of advantages: realize mouldless shaping, Optimize deformation path, the skinny device big shape part of shaping, easily be automated.
Multiple spot freeform fabrication is divided into according to forming mode: multiple spot is to pressing formation technology and multiple spot stretch forming technology.
When running into local curvature and changing greatly to pressing formation technology, easily there is gauffer, and springback capacity is bigger in multiple spot.Many Point stretch forming technology, compares multiple spot to pressing formation technology, and its springback capacity is little, formed precision is high, wrinkle resistant pleat.Multiple spot now Automobile rearspring forming technique is all the mechanical stretching form that uses, such as, carry out mechanical stretching with clamp clamping plate.And machinery draws Stretch forming mode and there is also following two or three kind of major defect: easily form stress concentration phenomenon in slab interior, to a lot of intensity For metal material that low, elongation percentage is little and some curved surfaces that more curvature is bigger, in drawing process, easily produce tear; Wasting very much material, in today of resource so shortage, this waste seems and particularly should not;Either multiple spot is to pressing formation technology Or multiple spot stretch forming technology, resilience is big, and its forming accuracy is the highest.
