The anti-falling alloy cutter head has the advantages that the design is reasonable; the structure is simple; the problem of hard alloy falling is solved; the hardness, the strength and the wear-resistant performance of the alloy cutter head are greatly improved; and the service life of the alloy cutter head is prolonged.
Description
Technical field
The present invention relates to a kind of coal-winning machine technical field, particularly relate to a kind of alloy cutter head of slip-off preventing.
Background technology
At present, along with the develop rapidly of process of industrialization, all kinds of mine substantially all achieves mechanized extraction operation, and adjoint and raw is that corresponding various facility and instrument match with large suitability for industrialized production.And wherein topmost digging instrument is exactly the pick of comprehensive mechanical coal mining machine, key component in pick is then alloy cutter head, because its condition of work is severe, requirement must possess high abrasion resistance and intensity, and its abrasion resistance and intensity directly have influence on application life, and then have influence on operating efficiency and the cost of production of pick.Conventional alloy cutter head all arranges hard alloy layer, but there is carbide alloy easily to come off problem, cause the inefficiency of alloy cutter head, causing carbide alloy to come off has following reason: one, and the carbide alloy made on alloy cutter head due to the deficiency of alloy cutter head in structure design easily comes off; Its two, on alloy cutter head, the abrasion resistance of carbide alloy is inadequate, causes cutting pick head premature abrasion like this.
Summary of the invention
Technical problem to be solved by this invention is the alloy cutter head providing a kind of slip-off preventing, solves carbide alloy and to come off problem, improve the abrasion resistance of alloy cutter head, intensity and lump coal rate, extend application life.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of alloy cutter head of slip-off preventing, it comprises active section and linkage section, it is characterized in that: on described active section, be processed with waved surface section and conical surface top two parts, described conical surface top is provided with diamond layer, is connected smoothly between described diamond layer and described waved surface section.
As preferred embodiment, the thickness of described diamond layer is 2 ㎜ ~ 4 ㎜.
As preferred embodiment, described diamond layer contains diamond and antifriction alloy.
As preferred embodiment, described waved surface section and conical surface top are that integral type is arranged.
As preferred embodiment, described waved surface section is made up of two convex surface conical section and a concave curved surface conical section, described concave curved surface conical section is positioned in the middle of two convex surface conical section, and described concave curved surface conical section and described two convex surface conical section are that integral type is arranged.
As preferred embodiment, for being connected smoothly between described concave curved surface conical section and described two convex surface conical section.
The invention has the beneficial effects as follows: because alloy cutter head adopts the design on waved surface section and conical surface top, make the hard alloy layer on alloy cutter head firm, greatly strengthen the adsorption of alloy cutter head body to hard alloy layer, make the hard alloy layer difficult drop-off on alloy cutter head; By technological means mold pressing diamond material on the conical surface top of alloy cutter head, and diamond itself to have hardness high, the features such as anti-wear performance is good, strengthen alloy cutter head anti-wear performance greatly, extend application life, substantially increase lump coal rate simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of alloy cutter head of the present invention;
In figure: 1-active section; 2-linkage section; 3-waved surface section; 4-conical surface top; 5-convex surface conical section; 6-concave curved surface conical section.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, a kind of alloy cutter head of slip-off preventing, it comprises active section 1 and linkage section 2, is convenient to easy for installation; Active section 1 is processed with waved surface section 3 and conical surface top 4 two parts, and the design of conical surface top 4 and waved surface section 3, strengthens the fastness of hard alloy layer on alloy cutter head, greatly strengthens the adsorption of alloy cutter head body to hard alloy layer; The features such as conical surface top 4 is provided with diamond layer, and it is high that diamond itself has hardness, and anti-wear performance is good, strengthen alloy cutter head anti-wear performance greatly, extend application life, substantially increase lump coal rate simultaneously; Be connected smoothly between diamond layer and described waved surface section 3, ensure that the wearing and tearing on alloy cutter head waveform curved sections 3 and conical surface top 4 in operation process are synchronously carried out, extend the application life of alloy cutter head.
The thickness of diamond layer is 2 ㎜ ~ 4 ㎜, is conducive to the lump coal rate of alloy cutter head.
Diamond layer contains diamond and antifriction alloy, substantially increases abrasion resistance and the intensity of alloy cutter head.
Waved surface section 3 and conical surface top 4 are arranged for integral type, are convenient to casting and processing, save time.
Waved surface section 3 is made up of two convex surface conical section 5 and a concave curved surface conical section 6, concave curved surface conical section 6 is positioned in the middle of two convex surface conical section 5, and concave curved surface conical section 6 and two convex surface conical section 5 are arranged for integral type, the design that waved surface section 3 is such, ensure that the fastness of carbide alloy on alloy cutter head, be conducive to the adsorption of bit body to carbide alloy, extend the application life of cutter head.
For being connected smoothly between concave curved surface conical section 6 and two convex surface conical section 5, being conducive to carbide alloy painting is located on cutter head face, there will not be seminess, extend application life, ensure that the wearing and tearing between waved surface section 3 different curve are synchronously carried out simultaneously.
The present invention has reasonable in design, easy to use, avoids carbide alloy and to come off problem, greatly strengthen abrasion resistance and the intensity of alloy cutter head, extend application life, and operating efficiency high.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
