Description
Technical field
The present invention relates to casting technology field, relates more specifically to what each operation in a kind of containerless casting technique was intelligently equipped
The system integration.
Background technology
Casting is one of most important forming technology, is infrastructural industry for the national economy.From automobile, lathe to Aero-Space, state
Anti- military project and daily life are both needed to casting, automobile casting more than 24%, lathe, hydraulic pressure pump valve and universal machine casting account for 65 again~
80%.The continuous 12 years the first in the world of China's casting output, the people of 30,000 Duo Jia Foundry Works more than 200 ten thousand working, 2013 more than 40,000,000
Ton, annual value of production cross 500,000,000,000 yuan.But China's conventional casting techniques fall behind, and labor intensity is big, the cycle is long, cost is high, casting accuracy
It is low.The casting dimension of the especially urgent need such as motor cylinder block cylinder cap, aero-engine, crankshaft used for large boat, propeller is big, shape is multiple
It is miscellaneous, wall thickness is greatly different, casting mold manufacture difficulty is big, and system need to be turned over more than ten sets or even tens molds, dimensional accuracy is difficult to ensure card, or even one
A little good structure designs can not moulding, turn into the exploitation of the Important Projects such as defence and military, Aero-Space, Grand Equipments and innovative technology
Bottleneck.
The Rapid Manufacturing Technology developed rapidly in recent years can be solved preferably caused by conventional casting technologies because of it
Various problems, it is especially most obvious in the quick manufacture view advantage of the intricate castings such as engine cylinder-body, cylinder cap, extensively should it obtain
With.What wherein application was most is non die-casting type Rapid Manufacturing Technology, and the technology eliminates Making mold link, sand lump is carried out straight
Processing is connect, the manufacturing cycle significantly reduces, and not only makes the selection of die joint have greater flexibility, is more easy to realize modeling scheme
Variation, so as to increase substantially the precision of intricate casting, mitigate blank weight, shorten the construction cycle of new product, reduction is opened
Cost is sent out, is the optimal solution of trial production of new products.But the technology needs to machine away a large amount of molding sand in sand lump process,
Cause molding sand to waste and extend process time, slow down the popularization and application of industry.Therefore be badly in need of by sand mold cutting technology with it is new
Quick preform technique organically combines, and the molding sand brought with reducing sand mold cutting wastes, and further shortens the Casting mold manufacturing cycle.
Further, since by foundry engieering and casting equipment etc. it is backward in technique limited, China is in large complicated casting
It is bigger with developed country gap in terms of the casting digital intelligentization of part, only moulder in most enterprises castings production flow
Sequence substantially carries out automation, and coremaking operation part realizes semi-automation, and other processes are more by manual operations；Cross number of passes
According to by manually gathering, systematization, intellectuality is not formed substantially, production efficiency is low, and product quality is uncontrolled, causes casting
Percent defective is up to more than 10%.Therefore, it is badly in need of being developed based on the sand mold extruding of non die-casting type Rapid Manufacturing Technology and cuts into
The system integration of shape equipment, lower core and the intelligent apparatus such as group core manipulator or automatic material flow dolly, it is large complicated to realize
The digitlization and intellectuality of the whole process link such as moulding, coremaking, group type/core, melting, mould assembling cast in cast casting production,
And then make it that casting accuracy is high, surface quality is good, raw material, energy resource consumption are low.
