Description
Technical field
The utility model relates to a kind of carbide alloy processing blade, refers in particular to a kind of disconnected groove indexable insert tip, throw away tip of making of carbide alloy of cutting of stainless steel semifinishing.
Background technology
At present, along with China's rapid economy development, the people produce that running water is flat to improve constantly, and stainless steel has entered each different industry.Stainless steel is the abbreviation of stainless steel and acid resisting steel.In metallurgy and material science,, greater than 10.5%, and be that a series of ferrous alloys of main serviceability are called stainless steel with corrosion resistance and rustless property with chrome content according to the main performance feature of steel.Usually stainless and corrosion resistant steel grade in the more weak medium of corrosivity such as atmosphere, water vapour and fresh water is called stainless steel; Be called acid resisting steel in the strong environment of corrosivity such as acid, alkali, salt, having corrosion proof steel grade.Two steel classes have different corrosion resistances because of the difference on the composition has caused them, and the former alloying level is low, and is generally not acidproof; Latter's alloying level height not only has acid resistance but also have rustless property.
Because it has good serviceability stainless steel material, is used widely in daily productive life.But this drawing abillity is poor, and as 100%, the relative machinability of austenitic stainless steel 1Cr18Ni9Ti is 40% with the machinability of common No. 45 steel; Ferritic stainless steel 1Cr28 is 48%; Martensitic stain less steel 2Cr13 is 55%.Wherein, the poorest with the machinability of austenite and austenite+ferritic stainless steel.Stainless steel mainly shows the following aspects in the machinability difference: 1) work hardening is serious; 2) cutting force is big; 3) cutting temperature height; 4) not frangibility, easy bonding of smear metal; 5) cutter is easy to wear.So be necessary its processing characteristics is studied.
Improving stainless processing characteristics can be improved from the following aspects: at first will select proper cutting tool materials, a large amount of wear-resisting elements is arranged in the stainless steel, so in the part processing process, cutter is easy to wearing and tearing; Secondly being exactly to select suitable process tool geometric parameter according to the characteristics of stainless steel material, is the method for the most simply improving cutting performance by choosing suitable tool geometrical parameter, and therefore many researchs all are to launch around this respect.
The utility model content
The purpose of this utility model is exactly in order to overcome the deficiency of existing stainless process tool, to start with from changing the tool geometrical parameter aspect, a kind of disconnected groove indexable insert tip, throw away tip of cutting of stainless steel semifinishing that is more suitable for adding stainless steel processing being provided.This kind blade has strong shock resistance, and the heat in metal cutting that has solved effectively in the stainless steel processing is big, difficult points such as sticking cutter.
The technical scheme that its technical problem that solves the utility model adopts is: the disconnected groove indexable insert tip, throw away tip of cutting of a kind of stainless steel precision processing, according to stainless steel material in machinery adds, difficult chip breaking, the cutting temperature height, sticking cutter is serious, be very easy to produce built-up edge, thereby very easily make cutting tip wearing and tearing and burst apart, durability is low, inefficient characteristics, and the utility model utility model is big according to stainless steel semifinishing processing capacity, the characteristics that temperature is high, start with from changing blade chip breaking chip breaking, the blade chip breaking is more prone to, thereby reduces the heating of process blade, and on blade, increase chip-breaker, take the structure of two-sided chip breaking grooved, be provided with compound profile chip-breaker type at two-sided main cutting edge place, be beneficial to chip removal.Stainless steel semifinishing of the present utility model is disconnected cuts the indexable insert tip, throw away tip that the groove indexable insert tip, throw away tip is two-sided chip breaking grooved, and the indexable carbide chip of W type that the indexable insert tip, throw away tip profile is adopted international standards has centre bore; Its characteristics are the two-sided chip-breaker that all is provided with at each main cutting edge place of indexable insert tip, throw away tip; Described chip-breaker is divided into main chip-breaker and wedge angle chip-breaker; Main chip-breaker is two anterior angles and cutting edge inclination grooved, and first anterior angle is and 14 °-16 ° of horizontal plane angles in two anterior angles, and second anterior angle is and 20 °-22 ° of horizontal plane angles; The cutting edge inclination of main chip-breaker also is two inclination angles that are, first cutting edge inclination is and 49 °-51 ° of horizontal plane angles that second cutting edge inclination is and 37 °-39 ° of horizontal plane angles; The wedge angle chip-breaker also is two anterior angles and cutting edge inclination grooved, and first anterior angle is and 11 °-13 ° of horizontal plane angles in two anterior angles of wedge angle chip-breaker, and second anterior angle is and 19 °-21 ° of horizontal plane angles; The cutting edge inclination of wedge angle chip-breaker is 18 °-20 °; Main chip-breaker and wedge angle chip-breaker are in the two sides of blade cut sword symmetric arrangement.In addition, be provided with on the rooved face of each main chip-breaker and help chip breaking polygon protruding block, protruding block is two to three, symmetric arrangement.
The beneficial effects of the utility model are: the utility model has designed a kind of indexable insert tip, throw away tip of two-sided chip breaking grooved, two-sided main cutting edge place is designed to compound profile chip-breaker type and is beneficial to chip removal, special two anterior angles and the design of cutting edge inclination grooved, cutting edge is sharp, to reduce cutting resistance.Thereby improve the durability and the production efficiency of blade, stablize processed surface quality.
