Abstract
The invention discloses a bi-metal composite plate hammer for an impact type ore crusher. The bi-metal composite plate hammer comprises a main shaft and a rotor body arranged on the outer surface of the main shaft. A plurality of protruding trapezoid bodies are evenly distributed on the outer surface of the rotor body in the circumferential direction and provided with plate hammer bodies. Rectangular grooves are formed in the upper end faces of the plate hammer bodies, and trapezoid grooves are formed in the lower end faces of the plate hammer bodies. The trapezoid grooves and the trapezoid bodies are correspondingly arranged and fastened through a plurality of bolts arranged in the rectangular grooves in the axial direction. Nuts of the bolts are further connected with steel wires in series. A plurality of hard alloy bars are further inlaid and cast in the plate hammer bodies. The bi-metal composite plate hammer is long in service life, low in cost, high in safety, suitable for crushing high-temperature materials, capable of facilitating machining, firm in structure and high in utilization rate.
Description
Technical field
The present invention relates to a kind of impact type spallar double metallic composite material bar.
Background technology
Impact type spallar is the machinery that the rebound effect of a kind of high speed impact utilizing bar and counterpunch board makes material broken, material enters the instantaneous touch of the bar being subject to high speed rotating after in machine and impacts, the tangential direction rotated along bar throws at a high speed the counterpunch board hung on body, return to again bar revolution space after producing shock with counterpunch board to come, in this process, also there is the collision of material and storeroom simultaneously, bar is formed repeat impact by such material, makes bar surfacing repeatedly deform and form abrasion.Bar is the critical piece of broken material in impact type spallar, and bar position is then primarily subjected to stronger impulsive force and frictional force.Because potassium steel has good Work Hardening Characteristic and higher toughness, so bar is mostly potassium steel material, ordinary sand casting mode is adopted to produce.But, common high-manganese steel plate hammer generally can only use about one week continuously, and its main failure mode is abrasive wear.It addition, existing bar is fastened in rotor block boss side surfaces, can only using by one side, namely after a surface wear, bar is just scrapped, and stock utilization is low, and service life is short.
Summary of the invention
It is an object of the invention to provide a kind of long service life, cost is low, safety is high, suitable in crash high temperature material, be easy to processing, structure is firm and utilization rate is high impact type spallar double metallic composite material bar.
The technical scheme is that, a kind of impact type spallar double metallic composite material bar, including main shaft and be installed on the rotor block on the outerface of spindle, described rotor block outer surface is uniformly distributed circumferentially the prismatoid being provided with multiple projection, described prismatoid is provided with bar, described bar upper surface is provided with rectangular recess, described bar lower surface is provided with trapezoidal groove, described trapezoidal groove and prismatoid are correspondingly arranged and by multiple bolts fastening axially disposed in rectangular recess, the nut of described bolt has also been arranged in series steel wire, go back castingin in described bar and be provided with some hard alloy bars.
In a preferred embodiment of the present invention, described bolt is provided with 4-6.
In a preferred embodiment of the present invention, bottom surface, described trapezoidal groove both sides is arranged with the laminating of described rotor body face.
In a preferred embodiment of the present invention, the diameter of described hard alloy bar is 10-15mm.
In a preferred embodiment of the present invention, described bar adopts potassium steel to be matrix with hard alloy bar setting spaced apart in matrix.
Of the present invention is a kind of impact type spallar double metallic composite material bar, bar imbedding hard alloy bars of the present invention, bar service life is greatly improved, thus reducing the comprehensive use cost of bar；Bar with the good potassium steel of impact flexibility for matrix, with hard alloy bar in matrix spaced apart, it is to avoid fracture damage, provide guarantee to safety in production；Hard alloy has that hardness is high, wear-resisting, intensity and a series of premium properties such as toughness is better, heat-resisting, corrosion-resistant, and particularly its high rigidity and wearability, even if being also held essentially constant at the temperature of 500 DEG C, be more suitable for for crash high temperature material；Composite bar has given full play to the advantage of bi-material, extends more than 3 times service life；This rotor block and board hammer structure are simple, it is simple to processing, and bar and rotor block are firmly combined with, steel wire of contacting on connecting bolt nut, have reached effective locking purpose；Bar is symmetrical structure, can turn around to use another side, improve the utilization rate of material after a surface wear.

Described rotor block 2 outer surface is uniformly distributed circumferentially the prismatoid being provided with multiple projection.
Described prismatoid is provided with bar 3, described bar 3 adopt potassium steel be matrix castingin with hard alloy bar 5 setting spaced apart in matrix, described bar 3 upper surface is provided with rectangular recess, and described bar 3 lower surface is provided with trapezoidal groove.
Described trapezoidal groove and prismatoid are correspondingly arranged and are fastened by multiple bolts 4 axially disposed in rectangular recess, and described bolt 4 is provided with 4-6, and bottom surface, described trapezoidal groove both sides is arranged with the laminating of described rotor block 2 surface.
The nut of described bolt 4 has also been arranged in series steel wire 6.
The diameter of described hard alloy bar 5 is 10-15mm.
A kind of alloy material that hard alloy is made up by powder metallurgical technique of hard compounds and the binding metal of refractory metal.Hard alloy has that hardness is high, wear-resisting, intensity and a series of premium properties such as toughness is better, heat-resisting, corrosion-resistant, and particularly its high rigidity and wearability, even if being also held essentially constant at the temperature of 500 DEG C, still have significantly high hardness when 1000 DEG C.The bar 3 of imbedding hard alloy bars substantially increases hardness and heat resistance, is more suitable for crash high temperature material.
