The utility model has the characteristics of the crystalline grain that makes hypereutectic high chromium cast iron board hammer refines, and the crystal boundary purifies, and the inclusion reduces, carbide dispersion distribution to can increase substantially hypereutectic high chromium cast iron board hammer's wearability and safety in utilization.
Description
Technical Field
The utility model discloses the high chromium cast iron flat hammer of hypereutectic that resistance to wears of installation on the impact crusher rotor, in particular to the optimization of the high chromium cast iron flat hammer internal organization of hypereutectic.
Background
The impact crusher is generally used for crushing materials in the industries of mines, chemical engineering, building materials and the like, particularly for crushing hard rocks such as granite, sandstone, shale, silica, volcanic rock, cobblestone and the like, is used for crushing silicon-adding raw materials in the industries of producing sandstone aggregate, machine-made sand and cement, provides granularity guarantee for grinding of a subsequent grinder, reduces the energy consumption of the grinder with higher energy consumption, and realizes energy conservation of more grinding and less grinding.
At present, the impact crusher is mostly used for two-stage crushing of materials, and because the plate hammer arranged on the rotor of the impact crusher receives great material impact force in the high-speed rotation process of the rotor. The abrasion resistance of the plate hammer made of high-toughness high-manganese steel material is insufficient; by using the high-chromium cast iron plate hammer, the fracture accident of the plate hammer mounting part is easy to occur under the action of large impact force. Therefore, the plate hammers used in the conventional impact crusher are all flat and straight square plate hammers, and the plate hammers are designed to be thick in order to increase the impact resistance of the plate hammers, so that the waste of materials is caused.
Disclosure of Invention
In order to solve the problem, the utility model provides a high chromium cast iron board of enhancement mode hypereutectic both can design into the attenuate bar that accords with the best inclination shape of impact force and the big square bar of thickness like this, has improved the life of bar. And the compactness of the internal structure of the plate hammer, the refined crystal grains and the purified crystal boundary are further improved, so that the impact resistance toughness of the whole plate hammer is improved, and the risk of fracture in the use process of the plate hammer is reduced.
The utility model discloses a following technical scheme realizes:
the utility model provides a reinforcing hypereutectic high chromium cast iron core board hammer, includes the board hammer body, and the middle part of board hammer body is the installation department, inlays in the inside flexible material layer that is equipped with of board hammer body that the installation department corresponds, and flexible material and the compound as an organic whole of board hammer body, flexible material layer are the chamber type structure, and the formation is bent into by the reinforcing bar net that the reinforcing bar was woven to the chamber type structure, and the board hammer body is hypereutectic high chromium cast iron board hammer.
The opening end of the cavity structure corresponds to the installation part, and the outer surface of the cavity structure is further provided with a plurality of reinforcing ribs.
According to the reinforced hypereutectic high-chromium cast iron plate hammer, the shape of the cavity structure is consistent with that of the plate hammer body.
The utility model has the advantages that:
1. the chemical components are optimally selected on the basis of common high-chromium cast iron on the premise of not increasing or slightly increasing the cost, and a hypereutectic high-chromium cast iron material is used.
2. The flexible material with a certain proportion is embedded in the high-chromium cast iron, so that the advantages of the internal chill are exerted, the density of the base body of the high-chromium cast iron plate hammer mounting part is enhanced, and the internal tissue defects of the plate hammer are reduced. Meanwhile, the impact resistance toughness of the plate hammer can be improved by the aid of the flexible materials embedded in the plate hammer, mutual linkage between the plate hammers is enhanced, and when the plate hammers are integrally broken, large plate hammers cannot fall into a breaking cavity to cause major quality accidents of damaging the whole rotor.
The utility model has the characteristics of the crystalline grain that makes hypereutectic high chromium cast iron board hammer refines, and the crystal boundary purifies, and the inclusion reduces, carbide dispersion distribution to can increase substantially hypereutectic high chromium cast iron board hammer's wearability and safety in utilization.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a sectional view taken along line a-a of fig. 1.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1-2, a reinforced hypereutectic high-chromium cast iron hammer comprises a hammer body 1, wherein the middle part of the hammer body is an installation part 3, a flexible material layer 2 is embedded in the hammer body corresponding to the installation part, the flexible material layer and the hammer body are compounded into a whole, the flexible material layer is of a cavity structure, the cavity structure is formed by bending a reinforcing mesh woven by reinforcing steel bars, namely the reinforcing mesh is bent into a box structure with one open end, and the hammer body is the hypereutectic high-chromium cast iron hammer. The flexible material is embedded in the plate hammer body, so that the function of internal chill is achieved, and the impact toughness of the plate hammer body is improved.
The open end of the cavity structure corresponds to the installation part, a plurality of reinforcing ribs 4 are further arranged on the outer surface of the cavity structure, and the shape of the cavity structure is consistent with the structure of the plate hammer body and can be set into a cylinder or a cuboid.
The utility model discloses the installation department is fixed on the impact crusher rotor, and at the rotatory in-process of rotor adjustment, the board hammer body strikes the broken material of institute, makes the material produce cracked.
The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and such improvements and modifications are also considered to be within the scope of the present invention.
