Description
Technical field
The utility model is related to crusher jaw technical field, and more specifically a kind of potassium steel inlays rich chromium cast iron jaw
Plate.
Background technology
At present, as development in science and technology is required, in the past as the potassium steel of trump high-abrasive material, its single matrix material is not
Double requirements of hardness and impact flexibility in use can be met, to increase the use time of wearing piece, hardness is increased on its matrix
Higher high-abrasive material, to improve work use time.The purpose of casting is inlayed, one is reliable for the use of single-casting
Property, it is continuing with traditional high tenacity and surface can processes hardening（Hardness can reach more than HRC40）Potassium steel is matrix, it is ensured that
It is overall during production and application not ftracture（Fracture）；Two be the crucial position easy to wear in this matrix, inlay hardness can reach HRC60 with
On rich chromium cast iron so that the wear-resistant service life of product is significantly improved.
Existing bimetal composite casting, using bimetal liquid laminated pouring, temperature is too high or interval time is too short easily
Cause molten metal to obscure, temperature is too low or interval time it is long easily cause faying face cold shut, lower material property, and combine
There is stomata, oxidation plus the defect such as slag because of high-temperature oxydation in face, exist all the time in use ftracture, come off, being layered etc. it is hidden safely
Suffer from.Further, since the casting character of material is different, the high chromium body of casting of potassium steel body shrinkage ratio is big by 1/3, after solidification from high temperature to room
Unavoidably occur bending and deformation or ftracture when warm, the reason for carbon component high because of rich chromium cast iron, plasticity is very low can not to pass through correction
Deformation or Repair Welding, heat treatment（Potassium steel wants water-tenacity treatment, and rich chromium cast iron wants air hardening）Method is different, if in casting
When just metallurgical machinery connect, will be unable to be heat-treated product.Therefore, it is difficult that potassium steel is combined that production, which is, in aforementioned manners
Rich chromium cast iron bimetal liquid moulding by casting curved surface large scale casting.
Patent CN201520032029 discloses a kind of potassium steel jaw plate structure, includes potassium steel jaw body, described
Body working face is interval with the raised line of broken material, and the tab parallel material down direction arrangement is set on the raised line
Have in the open slot towards outer face, the open slot and be inlaid with high chromium cast iron layer.The patent high chromium cast iron layer and potassium steel jaw
Plate body faying face requires high because of reasons in structure operation, is difficult to accomplish to be fitted close in production.
Utility model content
The purpose of this utility model is to overcome prior art high chromium cast iron layer with potassium steel jaw body faying face because of knot
The operation of structure reason requires high, be difficult in production accomplish close-fitting defect there is provided one kind it is simple and reasonable, fabricate into
This is low so that high manganese steel casting matrix and rich chromium cast iron mosaic block can individual cast and heat treatment, and inlay rich chromium cast iron
Block is simply and reliably combined with potassium steel, and the potassium steel that will not be ftractureed, come off under the operating mode that sharp impacts are worn and torn
Inlay rich chromium cast iron jaw.
In order to reach object above, the utility model is achieved through the following technical solutions：A kind of potassium steel inlays height
Some spaced and parallel arrangements are provided with chrome cast iron jaw, including high manganese steel casting matrix, the high manganese steel casting matrix
Tooth peak and the tooth paddy being interspersed between adjacent two teeth peak, it is characterised in that be provided with every tooth peak outside several
It is small it is inner be greatly trapezoidal chamber dovetail groove, a volume is provided with each dovetail groove less than its cavity and trapezoidal body
Rich chromium cast iron mosaic block, four trapezoidal sides of prismatoid of the rich chromium cast iron mosaic block and four, the trapezoidal chamber of the dovetail groove
In trapezoidal cavity wall in four groups of mating surfaces facing with each other, at least one of group of mating surface but at most wherein three groups mating surfaces are veneer
Be abutted against, remaining wherein at most three groups mating surfaces but at least one set of mating surface is spaced apart, and be spaced apart that several assemble conjunction
High manganese welding electrode obturator is filled with face in each group interstitial spaces.
Filled preferably, being abutted against in that several groups of mating surfaces being closely abutted against in each group in gap filled with epoxy resin
Body.
Preferably, in first inserting some potassium steel plugs in each group interstitial spaces in that several groups of mating surfaces being spaced apart
Bar, then refills high manganese welding electrode obturator.
Preferably, rich chromium cast iron mosaic block is highlighted in outside the dovetail groove of high manganese steel casting matrix.Certain rich chromium cast iron edge
Abaculus also can be highlighted partly in outside the dovetail groove of high manganese steel casting matrix.
Beneficial effect：The utility model does the dovetail groove and rich chromium cast iron mosaic block on the high manganese steel casting matrix flank of tooth
Into up-small and down-big prismatoid, first poured into after appropriate epoxy resin in dovetail groove, place into rich chromium cast iron mosaic block, and by height
Chrome cast iron mosaic block pushes side in dovetail groove to, is held up using type gap is carved between dovetail groove and rich chromium cast iron mosaic block, and
The gap that rich chromium cast iron mosaic block is available with dovetail groove residue is then filled with potassium steel tent, is finally welded with high manganese welding electrode
Jail.
Thus, such mosaic mode is just reliable in use, and high manganese steel casting matrix and rich chromium cast iron mosaic block can
Individual cast and heat treatment, and rich chromium cast iron mosaic block is simply and reliably combined with potassium steel, and in sharp impacts
It will not ftracture, come off under the operating mode of abrasion.
