Description
Technical field
The utility model relates to a kind of impact crusher rich chromium cast iron board hammer structure.
Background technology
Impact breaker is different from jaw crusher, its main principle is the percussion that utilizes material to produce in high speed and carries out crushing operation, enter the material of disintegrating machine body in the runner of setting, through the repeated stock effect of certain hour and certain stroke on first, second counterpunch board shock surface, finally realize material fragmentation.In the process of this impact crusher work, the fragmentation of material mainly by high speed impact on bar time to occur.Because the crusher chamber of impact breaker inside is larger, under the effect of impact crusher bar, material has enough spaces fully to accelerate and possesses certain kinetic energy, thus produce enough impulsive forces, counterpunch board is clashed into the spinner velocity of two times, realize partial crushing, and rear portion material can mutually clash in the process accelerated and be pulverized further aloft.Now widely used tup is all adopt rich chromium cast iron manufacture.For a medium scale Mineral Processing Enterprises, rich chromium cast iron bar consumes 5-8 ton in one day, within one month, consumes 150-250 ton, and within 1 year, (calculating with 10 months) will consume 1500-2500 ton; If 1.5 ten thousand yuan of calculating per ton, within 1 year, will consume 2200-3700 about ten thousand yuan, production cost is very high.
Utility model content
Technical problem to be solved in the utility model is the deficiency existed for above-mentioned technology, provides a kind of wear-resisting, rich chromium cast iron board hammer structure that use cost is low.The technical scheme realizing above-mentioned purpose is as follows:
Honeycomb ZTA Ceramic Composite rich chromium cast iron board hammer structure, comprise bar body, the working face of bar body is inlaid with several piece ceramic layer, it is characterized in that: described ceramic layer is ceramic pellet, wherein said ceramic pellet, substantially in a rectangular structure, the end face of ceramic pellet arranges one or more open-work, and the edge end face of ceramic pellet simultaneously arranges several groove, open-work is axially parallel with groove, fills and presents the ceramic powders being bonded in a piece respectively in open-work and groove.
Preferably, the ceramic powders upper molten metal in open-work and groove is filled and presented.
Preferably, described ceramic powders is ZTA ceramic particle.
Preferably, described open-work is four, wherein the line of four open-works and the center superposition of bar body, and four open-works are square arrangement, and the centre distance between adjacent open-work is 13.333 millimeters.
Preferably, the groove wherein bar body every bar edge end face arranged is two.
Preferably, the line of each groove and open-work forms a rectangle, and the center of groove on a line and open-work point-blank.
Preferably, the length and width of bar body is 40 millimeters.
Preferably, described bar body is rich chromium cast iron.
Compared with prior art, on the basis of traditional casting technique, we adopt rich chromium cast iron to mix with ZTA pottery and cast, and at the wearing part of rich chromium cast iron bar, inlay ZTA pottery.The rich chromium cast iron bar inlaying ZTA pottery achieves rich chromium cast iron and ceramic perfect adaptation, the anti-wear performance of rich chromium cast iron bar is improved greatly, namely improve the scuff resistance of rich chromium cast iron bar, turn increase the service time of rich chromium cast iron bar, decrease the number of times changing rich chromium cast iron bar, improve production efficiency, save production cost.

Fig. 2 is ceramic layer structure schematic diagram
Figure number illustrates: bar body 1, ceramic layer 2, open-work 3, groove 4,
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In figure, honeycomb ZTA Ceramic Composite rich chromium cast iron board hammer structure, comprises bar body 1, and because bar is in the process of work, working face easily weares and teares, and therefore on the working face of bar body 1, is inlaid with several piece ceramic layer 2.
Described ceramic layer is ceramic pellet, wherein ceramic pellet is substantially in a rectangular structure, the end face of ceramic pellet is arranged one or more open-work 3, the edge end face of simultaneously ceramic pellet arranges several groove 4, open-work is axially parallel with groove, preferred open-work is four, the wherein line of four open-works and the center superposition of pellet main body, and the line of four open-works is square arrangement, and each open-work is positioned on a foursquare angle, centre distance between adjacent open-work is 13.333 millimeters, the groove that preferred rectangular structure every bar edge end face is arranged is two, and the line of centres of each groove and open-work point-blank, the line of centres of groove and open-work forms a rectangle.Fill and present the ceramic powders being bonded in a piece respectively in each open-work and groove, ceramic powders is ZTA ceramic particle, has filled and presented after ceramic powders at ceramic powders upper metal liquid.Form certain many hollow structures between the ceramic powders be bonded together, the molten steel of conveniently building infiltrates in the gap between ceramic powders, strengthens structural strength.The length and width of preferred pellet main body is 40 millimeters.
The raw material of preparation ZTA ceramic particle:
Manufacturing diameter is the ceramic powder particle of 30-120um, pre-burning is carried out after ceramic powder particle dry-pressing being become block with isostatic pressing machine, calcined temperature 1100-1200 DEG C, then broken, screening particle diameter is that the ZTA ceramic particle of 1-3mm carries out high temperature sintering again, firing temperature 1600-1650 DEG C, obtains ZTA ceramic particle in irregular shape.Ceramic particle is mixed with a certain proportion of self-made binder, makes binding agent cover ceramic grain surface uniformly, be then filled in corresponding groove and open-work; Ceramic particle is joined to one another by binding agent, forms many hollow structures, and has higher intensity, can not be broken up in the process of cast 1450 DEG C of high-temperature alloy steel molten metals.
These are only the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; within all spirit in the utility model embodiment and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included in the protection domain of the utility model embodiment.
