The invention belongs to technical field of engineering machinery, the problem little in order to solve the filling scope of the internal material that non-solid casting exists, the present invention provides a kind of counterbalance weight of engineering machinery and preparation method thereof, including internal cored material and outside mould material, the outside internal cored material of mould material parcel, internal cored material includes combining split, and combination split synthesizes internal material to be cast according to der group from top to bottom, and outside mould material is cast in internal cored outer material side and is integrally formed.The present invention uses cored technique, can reduce raw material ore in sand form metal consumption, reclaims again facility simultaneously, contributes earth resource reutilization.The counterweight that the present invention makes compared to some special process also has bigger advantage, the integral forming process of the present invention, outer layer cast iron, magnesium iron or cast steel can be made to combine closely with internal layer material, there is not any gap, intensity and toughness are all greatly improved, safety is high, and cost is low, has good practicality and market using value.
Description
Technical field
The present invention relates to technical field of engineering machinery, particularly relate to a kind of counterbalance weight of engineering machinery.
Background technology
The balancing weight that engineering machinery is used at present is primarily used to guarantee, when engineering machinery uses operation, to can reach weight balancing,
Play the inherent function of engineering machinery, it is to avoid operation situation built on the sand produces, and reaches counterweight balanced action.
Current common counterbalance weight of engineering machinery is the balance weight utilizing iron casting monoblock solid, and minority is to use welding iron and steel material
Material manufactures balance weight, has with solid cast cast iron counterweight block, coordinates the size of stacker, and balancing weight at least will have one
The weight that ton is above, say, that solid cast balancing weight need to use the cast iron of more than one ton weight to manufacture, some balance weights
Weighing five tons, this solid cast balancing weight does not the most adapt to the most energy-conservation requirement, and has balance weight in prior art yet
The non-solid casting of internal employing, but non-solid casting there is problems of, and the filling of internal material is a problem, existing skill
Art, when for difference inside packing material, does not has the solution of reality, greatly reduces the optional scope of internal cored material,
Therefore it is badly in need of a kind of technical scheme and solves this state of the art.
Summary of the invention
It is an object of the invention to provide that a kind of intensity is high, toughness strong, save material, cost is low, performance is good engineering machinery is put down
Weight and preparation method thereof.
A kind of counterbalance weight of engineering machinery, including internal cored material and outside mould material, the outside internal cored of mould material parcel
Material, internal cored material includes combining split, and combination split synthesizes internal material to be cast according to der group from top to bottom,
Outside mould material is cast in internal cored outer material side and is integrally formed.
The inside cored material of the present invention, for making molding in advance, according to different needs, selects different inside cored materials, presses
Become, according to carrying out spatial summation from top to bottom, the shape required, internal cored material is placed in the mould of outside mould material, waters
Injection forming, expands the scope that internal cored material can be selected the most significantly, and various materials all may apply to the present invention's
In internal cored material, liberate the manufacture thinking of counterbalance weight of engineering machinery.
The outer surface of described inside cored material is provided with reserved groove or preformed hole.
The present invention is at the reserved groove of the outer surface of internal cored material and preformed hole, after outside mould material cast, outside
Mould material will form reinforcement with internal cored material or reinforcing prop is fixed so that outside mould material and internal cored
While material fits together completely, strengthen tightness therebetween.
Described outside mould material forms reinforcement at reserved groove or preformed hole or strengthens fixing post.
Described inside cored material includes metal, nonmetal, metal and non-metal mixture, and metal mixes solidification with binding agent
Body, nonmetal with binding agent mixing solidifying body, metal, nonmetal, binding agent three mix solidifying body；Here binding agent bag
Include cement, bath of glass.
Described outside mould material includes cast iron, magnesium iron or cast steel.
A kind of manufacture method of counterbalance weight of engineering machinery, including following small step:
(1) material selects
Requirement according to different engineering machinery and the dimensional requirement to balance weight, select the kind of internal cored material, internal cored
Material includes metal, nonmetal, metal and non-metal mixture, metal and binding agent mixing solidifying body, nonmetal and binding agent
Mixing solidifying body, metal, nonmetal, binding agent three mix solidifying body；Here binding agent includes cement, bath of glass；
Internal cored material molds makes
According to different size, make the mould of different inside cored materials；
(2) internal cored material molding
Inside cored material is filled in mould, is incubated molding；
(3) internal cored material release
(4) selection of outside mould material
Require to select different outside mould material, including cast iron, magnesium iron or cast steel according to different balance weights；
(6) Mold Making of outside mould material
(7) being put into by the inside cored material of different piece in outside casting machine, the engineering machinery spatially corresponded to actual needs is put down
The pattern of weight, is poured into outside mould material in the outside mould material mould made in advance；
(8) insulation molding, the demoulding.
The present invention uses cored technique, can reduce raw material ore in sand form metal consumption, reclaims again facility, to earth resource more simultaneously
Utilization contributes.The counterweight that the present invention makes compared to some special process also has bigger advantage, and the present invention's is one-body molded
Technique, can make outer layer cast iron, magnesium iron or cast steel combine closely with internal layer material, there is not any gap, intensity and toughness all
Being greatly improved, safety is high, and cost is low, has good practicality and market using value.
