【文章內(nèi)容簡介】 epresentative is Zn22%AL. 5 does not have the mold multi spots forming technology Does not have the mold multi spots fast forming technology is by CAD/CAM/CAT The technology is the main method about, may adjust the base main body group highly using the puter control to form forms the surface, replaces the traditional mold to carry on the three dimensional curved surface forming to the sheet an modern advanced manufacture technology. This technology may change the distortion way and the stressful condition at will, enhances the material the formed limit, may form repeatedly, by this elimination material interior remaining stress, the realization does not have 4 the snapping back forming 6 triumphant Uygur bright steel belt blanking falls the material pattern making technology The new steel belt blanking falls the material pattern making technology is one kind is different with has raised, the concave mold structure steel belt mold generally, it is with specially makes the new fast economical pattern making technology by the single edge steel belt which the backing strip is posed. This kind of mold weight is light, only then 200kg, the processing precision for 177。, may suit each kind of black and the nonferrous metal thick sheet processing generally. The life may achieve 525 ten thousand, the production cost is low. 7 molds semifinished materials fast manufacture technology solid casting Because the massive molds are belong to the single unit or the production, the mold semifinished materials manufacture quality and the cycle and the cost to the final mold quality and cyclical and the cost influence are very important. The modern mold semifinished materials widely have used the seeds casting technology, the socalled solid casting is (polystyrene PS either polymethacrylate PMMA) manufactures using the foam plastics replaces traditional the wooden mold or the metal pattern, after the modelling does not have to take out the model, then may the casting, under the foam plastics model high temperature liquid metal function, deflagrate the gasification but to vanish, the molten metal substitution original foam plastics model holds the position, after the condensation forms the casting. 8 other aspects technologies in order to simplify the mold the structural design, reduces the mold cost, reduces the mold manufacture cycle, in domestic and foreign also successively appeared some other aspects new technology application, like trades the mold frame, the ramming unit, the cutting edge builtup welding quickly, inlays the block casting, the nitrogen spring and so on. nitrogen springs on mold application The nitrogen spring is one kind of new elastic function part, replaces the spring, the rubber, the polyurethane or the air cushion with it side, it can accurately provide presses the strength, then may have the greatly initial ball pressure in the small space, does not need pre tightly, is basically hit the pressure basically in the mold entire work process to be constant. The ball pressure size and the working point position may, accurate, conveniently adjust as necessary, simplifies the mold to stretch, nearby the pressure, exdenning isostructuralism, simplifies the mold design, reduces the pattern making cycle, debugs the mold to be convenient, reduces the replacement mold time, enhances the production 5 efficiency. fast trades the mold technology Because product variety increasing, causes the mold in the production the transmutation extremely frequently, how thereupon reduces the ramming equipment the down time, enhances the production efficiency, fast traded the mold technology to receive people39。s attention. At present developed industrial nation some big panies traded the mold speed to achieve astonishing degree, wh
