Description
Technical field
This utility model relates to a kind of wear-resisting thrower head.
Background technology
Thrower head is when vertical shaft impact crusher works, subject the impact of high speed building stones and friction accelerated through rotor, it it is the important consumable accessory of vertical shaft impact crusher, and in prior art, thrower head includes metallic matrix and hard alloy liner plate two parts, utilize epoxy bond or use welding process to be attached manufacturing thrower head by metallic matrix and hard alloy liner plate, adhesion strength is limited, in use, have, under the constantly impact of high speed building stones, the risk that liner plate departs from metallic matrix, not only affect work efficiency, and Renewal process is time-consuming, use cost is high.
It addition, the service life of thrower head depends primarily on the service life of thrower head liner plate.In prior art, thrower head liner plate uses hard alloy manufacture, and hard alloy is that the carbide by refractory metal and binding metal are through powder metallurgical technique manufacture.On the one hand, being limited by the attribute of hard phase own, the space that hardness is substantially improved is little, on the other hand, much higher hard can cause hard alloy fragility to increase, therefore the space that hard alloy liner plate is substantially improved service life is little, limits the room for promotion in thrower head service life.
Utility model content
For the problems referred to above, this utility model provides a kind of wear-resisting thrower head, the wearability of raising thrower head work surface and wear parts and the bonding strength of metallic matrix, improves the service life of thrower head.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions:
A kind of wear-resisting thrower head, including metallic matrix, the end of described metallic matrix is provided with slotted eye, it is characterized in that, also include the diamond compact liner plate matrix being embedded in slotted eye, being provided with several composite polycrystal-diamonds on described diamond compact liner plate matrix, the medial surface of described metallic matrix is additionally provided with overlay cladding.
Preferably, diamond compact liner plate matrix is removably embedded in slotted eye, and such as, slotted eye is rectangular-shaped and two ends are provided with screwed hole, the two ends of diamond compact liner plate matrix are provided with the counter sink of correspondence, by screw fixed diamond composite sheet liner plate matrix and metallic matrix.
Or, diamond compact liner plate matrix is by welding or epoxy bond or takes epoxy resin glue bonding to fasten with screw simultaneously or takes to weld simultaneously and be fixed in slotted eye by the way of screw fastening.
Preferably, overlay cladding is strip and corresponding with several composite polycrystal-diamonds.
The beneficial effects of the utility model are: improve the wearability of thrower head work surface, ensure that thrower head wear parts and thrower head metallic matrix have higher bonding strength simultaneously, improve the service life of thrower head.

Detailed description of the invention
Being described in further detail technical solutions of the utility model with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As Figure 1-5, a kind of wear-resisting thrower head, including metallic matrix 1, the end of described metallic matrix 1 is provided with slotted eye 3, also include the diamond compact liner plate matrix 4 being embedded in slotted eye 3, being provided with several composite polycrystal-diamonds 5(on described diamond compact liner plate matrix 4 can be in shapes such as cylinder, cuboids), the medial surface (side towards in rotor chamber) of described metallic matrix 1 is additionally provided with overlay cladding 2.
Composite polycrystal-diamond (polycrystalline
Diamond compact, PDC), it is a kind of ultrawear-resistant material, it is to be sintered under the conditions of high pressure high temperature by diadust and cemented carbide substrate to form, and has the impact resistance of the high rigidity of diamond, high-wearing feature and hard alloy concurrently.As it is shown on figure 3, each composite polycrystal-diamond 5 includes polycrystalline diamond layer 8 and cemented carbide substrate 9.
Wherein, diamond compact liner plate matrix 4 can removably be embedded in slotted eye 3, or by welding, or epoxy bond, or take epoxy resin glue bonding and the dual fixed form of screw fastening, or take welding to be fixed in slotted eye 3 with the dual fixed form of screw fastening simultaneously simultaneously.
Preferably employ the first scheme, such as, as it is shown in figure 1, slotted eye 3 is in rectangular-shaped and be provided with screwed hole 6 at two ends, the two ends of diamond compact liner plate matrix 4 are provided with the counter sink 7 of correspondence, by screw fixed diamond composite sheet liner plate matrix 4 and metallic matrix 1.Using bead-welding technology to reinforce the position of slotted eye 3 close inside thrower head metallic matrix 1, overlay cladding 2 is shaped as strip.
In Fig. 1, overlay cladding 2 is in strip and corresponding with several composite polycrystal-diamonds 5, i.e. the length of overlay cladding 2 sets according to the length in diamond compact region.Composite polycrystal-diamond 5 side by side, be uniformly arranged on diamond compact liner plate matrix 4, and the quantity of composite polycrystal-diamond 5 can change with the change of liner plate size, the amount doesn't matter, depending on specifically used requirement.
Bead-welding technology is used to reinforce thrower head matrix to improve the service life of vertical shaft impact crusher thrower head, improve the wearability of thrower head work surface, ensure that thrower head wear parts and thrower head metallic matrix have higher bonding strength simultaneously, improve the service life of thrower head.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, is the most in like manner included in scope of patent protection of the present utility model.
