Abstract
The invention discloses a plate hammer for overlaying of an impact crusher. The plate hammer comprises a rotor body, a plurality of long-bar-shaped protruding bodies and plate hammer bodies. The long-bar-shaped protruding bodies are evenly distributed on the surface of the outer ring of the rotor body. Grooves are formed in the plate hammer bodies. The long-bar-shaped protruding bodies correspond to the grooves of the plate hammer bodies. Through bolt holes are formed in the long-bar-shaped protruding bodies, and step holes corresponding to the bolt holes are formed in the plate hammer bodies. Bolts penetrate the step holes and the bolt holes and are firmly fixed to lock nuts. Rectangular grooves are formed in the two sides of the surface of each plate hammer body in the axial direction, and abrasion-resisting alloy blocks are arranged in the rectangular grooves in an overlaying manner. According to the plate hammer for overlaying of the impact crusher, the rectangular grooves are formed in the two side faces of each plate hammer body and abrasion-resisting welding rods are arranged in the rectangular grooves in an overlaying manner so that abrasion-resisting layers can be effectively prevented from falling, and the service life of the plate hammer bodies is prolonged; and each plate hammer body is of a symmetric structure so that after one face is abraded, the plate hammer body can be turned round for use of the other face, and the service life is prolonged by double.
Description
Technical field
The present invention relates to a kind of impact breaker built-up welding bar.
Background technology
Impact breaker is a kind of machinery utilizing the high speed impact of bar and the rebound effect of counterpunch board to make material fragmentation, bar wearing and tearing belong to heavily stressed wearing and tearing, the instantaneous touch being subject to the bar of High Rotation Speed after in material ingress engine impacts, the tangential direction rotated along bar throws to the counterpunch board that body hangs at a high speed, with counterpunch board produce clash into after turn back to again bar revolution space come, in this process, also there is the collision of material and storeroom simultaneously, such material forms repeat impact to bar, bar surfacing is repeatedly out of shape and forms wearing and tearing.Therefore require that frayed bar material not only will have enough hardness, and more should have high strain fatigue strength and stress fatigue intensity.
Existing bar is fastened in rotor block boss side surfaces, and can only use by one side, namely after a surface wear, bar is just scrapped, and stock utilization is low, and service life is short, adopts the method for build-up wear-resistant welding rod, can increase the service life, but the wearing layer of built-up welding easily drops.
Summary of the invention
The object of the present invention is to provide one to have rectangular channel in bar two sides, build-up wear-resistant welding rod in rectangular channel, the phenomenon that can effectively prevent wearing layer from dropping, extends the service life of bar; Bar is symmetrical structure, can turn around to use another side, the impact breaker built-up welding bar that the life-span doubles after a surface wear.
Technical scheme of the present invention is, a kind of impact breaker built-up welding bar, comprise rotor block, strip convex body and bar, described strip convex body is provided with multiple and is uniformly set at the outer peripheral surface of described rotor block, described bar is provided with groove, described strip convex body is corresponding with the groove of bar to be arranged, described strip convex body is provided with the bolt hole run through, described bar is provided with the trapezoidal hole that arrange corresponding to described bolt hole, bolt is through described trapezoidal hole and bolt hole and the fastening setting of stop nut, both sides, described bar surface have rectangular channel vertically, in described rectangular channel, heap is welded with wear-resisting alloy block.
In a preferred embodiment of the present invention, the cross section of described strip convex body is rectangle.
In a preferred embodiment of the present invention, the two ends diameter of described trapezoidal hole is large, mid diameter is little.
In a preferred embodiment of the present invention, described wear-resisting alloy block width is 30-40mm, is highly 15-20mm, and length is 50-60mm.
In a preferred embodiment of the present invention, described bar is that symmetrical structure is arranged.
Of the present invention is a kind of impact breaker built-up welding bar, and the present invention has rectangular channel in bar two sides, build-up wear-resistant welding rod in rectangular channel, and the phenomenon that can effectively prevent wearing layer from dropping, extends the service life of bar; Bar is symmetrical structure, can turn around to use another side after a surface wear, and the life-span doubles.
Accompanying drawing explanation
Fig. 1 be a kind of impact breaker built-up welding bar of the present invention partly cut open structural representation.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Of the present invention is a kind of impact breaker built-up welding bar, as shown in Figure 1, comprises rotor block 1, strip convex body 2 and bar 3.
Described strip convex body 2 is provided with multiple and is uniformly set at the outer peripheral surface of described rotor block 1, and described bar 3 is provided with groove, and described strip convex body 2 is corresponding with the groove of bar 3 to be arranged.
Described strip convex body 2 is provided with the bolt hole run through, described bar 3 is provided with the trapezoidal hole that arrange corresponding to described bolt hole, bolt 4 is through described trapezoidal hole and bolt hole and the fastening setting of stop nut 5.
The described surperficial both sides of bar 3 have rectangular channel vertically, and in described rectangular channel, heap is welded with wear-resisting alloy block 6.
The cross section of described strip convex body 2 is rectangle.
The two ends diameter of described trapezoidal hole is large, mid diameter is little.
Described wear-resisting alloy block 6 width is 30-40mm, is highly 15-20mm, and length is 50-60mm.
Described bar 3 is symmetrical structure setting.
Adopt the hardfacing electrode of high-chromium alloy type, the surfacing layer of this kind of welding rod is generally martensite+this tissue morphology of retained austenite+carbide and has good abrasive wear resistant weld deposit performance.Because bar material is the surface overlaying that potassium steel is wearing and tearing, rear construction must be ground off by producing the part of work hardening, or with transition zone welding rod welding bottoming, thus prevent the generation of crackle.
Because potassium steel thermal conductivity factor is very low, easily produce larger thermal stress and structural stress, therefore must accelerate cooling velocity in welding process, make carbide have little time to fold, welding procedure must adopt small area analysis, discontinuous welding, weld interpass temperature must not more than 280 DEG C, the generation of Crack prevention.
Of the present invention is a kind of impact breaker built-up welding bar, and the present invention has rectangular channel in bar two sides, build-up wear-resistant welding rod in rectangular channel, and the phenomenon that can effectively prevent wearing layer from dropping, extends the service life of bar; Bar is symmetrical structure, can turn around to use another side after a surface wear, and the life-span doubles.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
