Description
Technical field
The utility model relates to a kind of milling cutter, has been specifically related to a kind of double knife-edge milling cutter for high-speed milling.
Background technology
Milling machine is processed capital equipment as modern metal cutting, is widely used in machine industry, and be plane, groove, the conventional lathe of hole and the processing of other molded surface.Normally used cutter has: cylindrical milling cutter, taper-shank cutter, cover face formula milling cutter, face and side cutter, double knife-edge milling cutter and saw blade knife etc.Wherein double knife-edge milling cutter process velocity is very fast and can obtain compared with high manufacturing accuracy, but during due to high-speed cutting, cutter head can produce a large amount of heats because of cutting, and a large amount of heats can make double knife-edge milling cutter, in high-speed cutting, tipping easily occur, and can not meet the processing of high efficiency typical products in mass production.
Solution is now to utilize shower nozzle directly cooling fluid to be injected on the cutter head of double knife-edge milling cutter, but during due to the high-speed cutting of double knife-edge milling cutter, a part of heat of the cutter head of double knife-edge milling cutter returns to the bare terminal end of double knife-edge milling cutter, the bare terminal end meeting expanded by heating of double knife-edge milling cutter, of long duration, being connected between double knife-edge milling cutter and milling machine will be become flexible; In addition cutter head used now easily produces the long-pending knurl of cutting, and the long-pending knurl of cutting can make the smear metal precision of double knife-edge milling cutter reduce.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of double knife-edge milling cutter for high-speed milling, its object: can be cooling fast when high-speed milling, and on cutting edge, be difficult for producing the long-pending knurl of cutting.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of double knife-edge milling cutter for high-speed milling, comprise body, body is made up of cutter head end, cutter neck and bare terminal end, cutter neck is arranged between cutter head end and bare terminal end, cutter head end comprises two ridges, the lateral surface on ridge top is provided with cutting edge, and ridge also comprises the curved surface and the arcwall face that are located at respectively cutting edge both sides, is provided with rounding off face between curved surface and arcwall face;
On bare terminal end, be socketed with splash guard, splash guard is provided with opening towards the end of cutter head end, and splash guard is sealing shape between the end of bare terminal end end and bare terminal end, and the inner chamber of splash guard is taper by sealed end to openend rounding off;
The end middle part of bare terminal end is provided with the first through hole, and bare terminal end sidewall is provided with the second through hole, and one end of the second through hole is connected with the first through hole, the other end of the second through hole and the intracavity inter-connection of splash guard.
Preferably, curved surface is made up of two planes and a cambered surface.
Pass through technique scheme, cool but liquid is directly injected into the first through hole, the first through hole is sprayed onto cooling fluid in the inner chamber of splash guard by the second through hole, the inner chamber of splash guard is taper by sealed end to openend rounding off, the inner chamber of splash guard can be gathered cooling fluid on the cutter head end that is sprayed directly on to double knife-edge milling cutter, wherein cool but liquid is to inject from the bare terminal end end of double knife-edge milling cutter, the heat being diffused in the bare terminal end of double knife-edge milling cutter can be taken away, make this double knife-edge milling cutter can be cooling fast in the time of high-speed milling, there is the loosening phenomenon of the connection occurring because expanding with heat and contract with cold in the bare terminal end that has prevented double knife-edge milling cutter, because the side of cutting edge both sides is respectively curved surface and arcwall face, guarantee that this double knife-edge milling cutter has the ability of quick chip removal, and because the temperature of this double knife-edge milling cutter is not high, therefore be difficult for producing the long-pending knurl of cutting on cutting edge.
