Description
Technical field
The utility model belongs to the component of impact breaker, and in particular to one kind is installed on impact crusher rotor
Wear-resistant bar.
Background technique
The material that impact breaker is generally used for the industries such as mine, chemical industry, building materials is broken, is particularly useful granite, sand
You, the hard rocks such as volcanic rock, cobblestone of rock, shale, silica are broken, increase silicon for producing sandstone aggregate, Machine-made Sand and cement industry
Raw material is broken, provides granularity for subsequent grinding machine grinding and guarantees, reduces the biggish energy consumption of mill that consumes energy, and realizes " more broken few mills " section
The about energy.
Currently, impact breaker is mostly used the two-stage crushing in material, because of the bar installed on its rotor, in rotor height
In fast rotary course, by very big material impact power.Using high tenacity high manganese steel material bar, wearability is insufficient；It uses
Rich chromium cast iron bar, under the effect of large impact power, fracture accident easily occurs for bar.So being used on general impact breaker
Bar, be all straight rectangular bar, and in order to increase the impact resistance of bar, bar all designs very thick big, this
Sample will cause the waste of material.
Utility model content
The utility model provides a kind of preset ceramic body cast iron bar, and thick big rectangular bar is designed to comply with reaction type
The bar of crusher rotor motion profile and impact force optimum tilt angle shape, improves the service life of bar.
The purpose of this utility model is achieved in that
A kind of preset ceramic body cast iron bar, including bar ontology, bar ontology is by mounting portion and is located at mounting portion two sides
Beating part constitute, have an inclination alpha between beating part and mounting portion, the tilt angle and impact crusher rotor at the inclination angle are transported
Dynamic rail mark and impact force match.
Above-mentioned preset ceramic body cast iron bar, is embedded with ceramic body in beating part, which is obtuse angle.
Above-mentioned preset ceramic body cast iron bar, the material of the ceramic body are wear-resistant ceramic.
Above-mentioned preset ceramic body cast iron bar, the ceramic body are successively embedded by ceramics preparative block and are formed in beating part.
Above-mentioned preset ceramic body cast iron bar, inclination alpha are 130 ° -165 °.
Above-mentioned preset ceramic body cast iron bar, the inclination alpha are 149 °, and the material of bar ontology is rich chromium cast iron.
Above-mentioned preset ceramic body cast iron bar, the preparation method of the ceramics preparative block are alumina ceramic grain and oxidation
Zircon ceramic particle is uniformly mixed, then is added binder and carried out blank preparation, is then placed in vacuum sintering furnace and is sintered, prepares
Wear-resistant ceramic prefabricated section out.
Compared with the existing technology, the utility model has the advantage that and thick big rectangular bar can be both designed in this way
The bar for meeting impact crusher rotor motion profile and impact force optimum tilt angle shape, improve bar uses the longevity
Life.Valuable alloy material is saved, the wearability at bar working face position is improved, extends the service life of bar.
Detailed description of the invention
Fig. 1 is the utility model sectional view.
Fig. 2 be the utility model along Fig. 1 A-A to sectional view.
Fig. 3 is B-B direction sectional view of the utility model along Fig. 1.
Specific embodiment
A kind of preset ceramic body cast iron bar as shown in FIG. 1 to FIG. 3, the bar are fixed on impact crusher rotor
Broken body.In rotor high-speed rotation, bar hits the material being crushed, and material is made to generate fragmentation.Therefore, bar
The impact resistance for hitting position is especially important.The utility model bar includes bar ontology, and bar ontology is by mounting portion 3 and position
Beating part 1 in mounting portion two sides is constituted, and has an inclination alpha, the tilt angle and counterattack at the inclination angle between beating part and mounting portion
Formula crusher rotor motion profile and impact force match, and make the bar being mounted on the rotor according to best angle of attack rammer
Material, the inclination alpha are obtuse angle.Ceramic body 2 is embedded in beating part, which plays the role of increasing bar wearability.
The material of the ceramic body of the utility model is wear-resistant ceramic, which is successively embedded by ceramics preparative block and is being hit
Portion is formed, and the preparation method of ceramics preparative block is that alumina ceramic grain is uniformly mixed with zirconia ceramics particle, wherein aoxidizing
Mass ratio (55-65) %:(35-45 of aluminium ceramics and zirconia ceramics) %, preferably 60%:40%, then add binder and carry out blank
Preparation, binder are refractory inorganic binder, and the additive amount of binder is the (2- of aluminium oxide and zirconia ceramics gross mass
3) %, preferably 2.5%, are then placed in vacuum sintering furnace and are sintered, and prepare wear-resistant ceramic prefabricated section.
The preferred technical solution of the utility model is that the inclination alpha between the beating part of bar and mounting portion is 130 ° -165 °,
Most preferably 149 °.
Above-mentioned preset ceramic body cast iron bar, the material of the bar ontology are rich chromium cast iron, the ingredient of rich chromium cast iron are as follows:
