Abstract
The invention discloses a reinforced type high-abrasion-resistance diamond composite cutting tooth. The cutting tooth comprises a cutting tooth stem, a cutting tooth base and a cutting tooth head, the cutting tooth base is connected to one end of the cutting tooth stem, the cutting tooth head is fixed into the cutting tooth base, the cutting tooth head comprises a hard alloy base body and a diamond alloy layer wrapping the end of the hard alloy base body, and the diamond alloy layer is formed by bead-welding diamond alloy powder on the surface of the end of the hard alloy base body. In the welding process of the diamond alloy powder, a temperature ranging from 1500 DEG C to 2000 DEG C needs to be generated within a half second, the diamond alloy powder is welded to the cutting tooth head so that the abrasion resistance can be enhanced, and the diamond alloy powder and alloy are made to be matched and abrased in the same proportion. According to the cutting tooth, the cutting tooth base material cannot be damaged by the instant high temperature, so that the toughness of the cutting tooth core is maintained, meanwhile, due to high hardness of the alloy and an alloy coating, sparks are rarely generated in the process of collision with rocks, and the service life of the cutting tooth is two to three times that of a traditional cutting tooth.
Description
Technical field
The present invention relates to pick technical field, be specifically related to a kind of reinforced high abrasion-proof diamond composite cutter bit.
Background technology
In prior art, mine, driving pick is key element on large-scale coal-winning machine and development machine, carbide alloy cutting pick head is welded with alloy steel together with (brazing) by general employing, it is mainly used in the digging field such as coal mining, tunnelling in coalfield, along with the growth increasingly of resource requirement, the use of large-scale mining machinery is more and more extensive, thus has higher requirement to the performance of digging pick.
At present, although the carbide alloy cutting pick head adopted has good anti-wear performance compared with steel, but the requirement in application life can not be met, and due to this kind of cutting-gear life not good, cause changing pick frequently, the efficiency of mining machinery can not be not fully exerted.Simultaneously, because cutting pick handle is prepared from by materials such as alloy steels, thus make cutting pick handle pole not wear-resisting, make too early the coming off of carbide alloy cutting pick head, whole pick is caused to damage inefficacy in advance, adopt traditionally cutting pick handle heat-treated or at cutting pick handle surface overlaying one deck wear resistance electrode to increase abrasion resistance, to reach gauge object, DeGrain.Particularly in the appearance of diamond compound pick head, the life-span of the cutting pick handle that its high-wearing feature high life makes more needs well to be ensured.
Summary of the invention
It is good that technical problem to be solved by this invention is to provide a kind of intensity, the reinforced high abrasion-proof diamond composite cutter bit that the life-span is long.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of reinforced high abrasion-proof diamond composite cutter bit, comprise cutting pick handle, pick box and cutting pick head, described pick box is connected to one end of cutting pick handle, described cutting pick head is fixed in pick box, described cutting pick head comprises hard alloy substrate and is coated on the diamond alloy layer on carbide matrix end of body, described diamond alloy layer by diamond alloy powder weld deposition on the surface of carbide matrix end of body, form diamond alloy layer, described diamond alloy powder is made up of the component of following mass percent:
Above-mentioned diamond alloy powder, when welding, needs to produce 1500-2000 DEG C in 0.5 second, and diamond alloy powder being welded on pick head increases abrasion resistance, makes it carry out coupling in alloy and accomplishes same specific wear.Because instantaneous high-temperature can not produce injury to pick mother metal, maintain the toughness of pick core, simultaneously in the high rigidity due to alloy and alloy-coated layer, be almost do not have spark to produce in the collision of rock, the life-span is 2-3 times of traditional pick.
Connected mode between described cutting pick head and pick box is copper brazing, and its welding procedure is as follows:
1. open the valve of welding gun, and light welding gun, now welding gun has black smoke to emerge;
2. rotate oxygen regulating valve, the flare on welding nozzle of welding gun is uniformly distributed, makes the flare temperature of tip reach 2900-3100 DEG C;
3. burn cutting pick head and pick box contact site with welding gun and keep tip distance welding position between 3-5cm, welding gun be made to move rapidly and uniformly, make contact site thermally equivalent, welding gun can't be made to rest on a position and treat that it melts;
4. visual cutting pick head and pick box, to the part spot heating that it not yet fuses, repairs rough part;
5. turn off welding gun, treat that solder joint cools, so far, weld complete.
The invention has the beneficial effects as follows: processing technology of the present invention easily realizes, and yields is high, is conducive to mass mechanized production, Article Stiffness Determination is high, abrasion resistance good, and its heat stability, thermal conductivity, elevated temperature strength etc. all have a clear superiority in; It can at high temperature continuous rapid operation, enhances productivity.
