Description
Technical field
The utility model belongs to foundry robot's equipment technical field, more particularly to a kind of wheeled removable heavy duty casting of omnidirectional
Make robot.
Background technology
The flexibility of industrial robot height disclosure satisfy that the various particular/special requirements in modernization Green foundry production, casting
Production uses robot, operator can not only be freed from heavy, dull manual labor, saves labour, and
And castings production efficiency, the accuracy of manufacture and quality are still improved, Foundry Production mechanization is realized, automates and civilise important
Means.At present, using advanced and applicable casting technology, casting equipment automatization level, particularly mobile robot are improved
The application of technology, it is that foundry enterprise implements Green foundry production, realizes the crucial behave of sustainable development.Because height be present in casting
Warm, high dust, vibration, greasy dirt, the adverse circumstances of noise and electromagnetic interference, and casting weight is big, therefore general industry robot
It can not meet to produce needs.Foundry robot will adapt to such working environment and normal operation, numerous crucial skills also be present
Art is badly in need of research and broken through.The casting that foundry robot cannot be only used in die casting, essence casting production is carried and transmission, is also used in
In the processes such as moulding, coremaking, lower core, cast, cleaning and the inspection of sand casting.Especially in the production of medium-and-large-sized casting
In, size, the weight of core and casting are all bigger, and it is big to perform coring, group core, lower core, cast and transport operation difficulty, it is desirable to
It is high.There is an urgent need to disclosure satisfy that coring in castings production, group core, lower core, cast and high flexibility, the heavy duty of transport operation demand
Mold casting robot.
At present, the robot used in Foundry Production is articulated type serial manipulator mostly, and its advantage is structure letter
It is single, easy to control, working space is big, but its precision is poor, load capacity is small, can only perform underloading job task.It is difficult to meet
Heavily loaded job task demand in medium-and-large-sized castings production, the raising of homework precision and efficiency are restricted.Existing casting machine
The application of people is also limited only to the auxiliary in fixed station and completes relatively simple casting manipulations task, can not adapt to Foundry Production
The accurate job requirements of complex job environment downward moving.The tandem pouring robot used in such as producing, although simple in construction,
Cost is relatively low, but because the free degree is very few, application scenario is single, can not meet the use of a variety of occasions.Commonly used casting
Robot is all come by ordinary robot's transformation of the way.At present, many small and medium-sized casting manufacturers are carried out in process of production
During the operations such as coring, group core, lower core and cast, apply the strategy of throwing waves of people into action more, one staff's coring of a station, lower core, group
Core and cast melt, staff must run back and forth, it appears and it is very mixed and disorderly, while operating efficiency is low.Core and casting
Transport operation is more based on human assistance simple and easy hoisting equipment, and it is also mostly fixed position that minority, which is used in the technical scheme of robot,
Tandem robot be equipped with pneumatic gripping device carry out operation, lack specialty packaged type heavily loaded foundry robot.Especially exist
During the pouring practice of medium-and-large-sized casting, still based on artificial, worker's work emphasizes that physical demands is more, operating efficiency greatly

In the cast rising head for pouring into a mould workpiece.At present, pouring molten iron or molten steel are the heavy casting ladles of handling of being lifted or driven a vehicle by worker's hand, from height
Molten iron or molten steel are connect at frequency electric furnace, then three, 400 jin of molten iron or molten steel and casting ladle are moved on to cast place, two people or more people match somebody with somebody
Close, casting ladle is tilted at leisure, the molten iron in casting ladle or molten steel are poured in the sprue gate of workpiece.Such a method has following lack
Point：(1) influenceed by loading weight of worker, the size (weight) of pouring piece is restricted, and casting will be when very short
Between in pour and be poured in, if with the molten iron or pouring molten steel of two bags or more bag, because the speed of worker is slow, the then casting for pouring into a mould out
Part is easy to the quality problems such as casting flaw be present；(2) labor intensity of worker is big, and working environment is poor.The temperature of molten iron or molten steel
Up to 1500 DEG C or so of degree, for its operating ambient temperature more than 40 DEG C, the labor intensity of worker is big, easily fatigue；(3) building ring
Border is dangerous, and the moment is careful molten iron or molten steel splashes, and the personal safety guarantee of staff has hidden danger；(4) transported in working
Speed is low, and poring rate is slow；Operating efficiency is low, and productivity ratio is low, adds manufacturing cost, has delayed manufacture progress.
For problem present in casting group core, lower core, cast and carrying, existing patent document it is also proposed some solutions
