Abstract
The invention discloses a high-hardness metal ceramic layer wear-resistant cutting tooth which comprises a cutting tooth body. The cutting tooth body is characterized in that the head of the cutting tooth body adopts a plasma cladding method to clad the high-hardness metal ceramic layer on the head of the cutting tooth body, the high-hardness metal ceramic layer has the advantages of being high in hardness, good in toughness, resistant to wear and impact and the like, the head of the cutting tooth body is well protected, the head tooth body wear speed is decreased, the tooth body and the alloy head are worn synchronously, and optimum matching is achieved.
Description
Technical field
The present invention relates to pick technical field, be specifically related to a kind of high rigidity cermet coating wear resistant cutting pick.
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 high rigidity cermet coating wear resistant cutting pick that the life-span is long.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of high rigidity cermet coating wear resistant cutting pick; comprise a pick body; it is characterized in that, adopt plasma cladding method at pick head cladding one deck high rigidity cermet coating at described pick body head, it is high that this high rigidity cermet coating has hardness; good toughness; the features such as wear and shock-resistant, well protect pick denticle head, reduce the head denticle rate of wear; denticle and alloy head are are synchronously worn and torn, reaches profile error.
Described high rigidity cermet coating is made up of the component of following mass percent:
The cladding method of above-mentioned high rigidity cermet coating is as follows:
1) above-mentioned raw material mixing is all obtained cermet composition;
2) above-mentioned cermet composition pressing mold is obtained green compact, at the temperature of 200-350 DEG C, toast 40-60 minute;
3) green compact after baking are carried out isostatic sintering under oxygen free condition, sintering pressure is 100-400MPa, and sintering temperature is 1600-2000 DEG C;
4) by sintering after green compact grind, granularity is 15 ~ 45 μm, and then by metal ceramic powder in drying box about 150 DEG C dry;
5) ratio that is mixed into that the metal ceramic powder after baking and cementing agent stirred is the paste mixture of 3:1 (mass ratio), evenly be coated in pick head, precoating powder thickness is 5mm, then inserts less than 80 DEG C oven dry or natural air drying in drying box;
6) pick preset is placed on the lathe of laser instrument, carry out Laser Cladding Treatment, laser cladding technological parameter is: power is 1.7 ~ 1.8kw, laser scanning speed 200 ~ 500mm/s, overlapping rate 30% ~ 40%, spot diameter 5mm, contextual analysis of organization finds, laser macro morphology cladding layer is smooth, fine and close, zero defect; The defects such as microstructure of surface cladding layer interior solid, pore-free and crackle.
Adopt argon gas as protective gas in described Laser Cladding Treatment process.
The invention has the beneficial effects as follows: processing technology of the present invention easily realizes; yields is high; be conducive to mass mechanized production; it is high that this high rigidity cermet coating has hardness, good toughness, the features such as wear and shock-resistant; well protect pick denticle head; reduce the head denticle rate of wear, denticle and alloy head are are synchronously worn and torn, reaches profile error.
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 specific embodiment, setting forth the present invention further.
