Abstract
The utility model discloses an impeller milling cutter, which comprises a cutter main body, wherein one end of the cutter main body is provided with a cutter handle, one end of the cutter handle is provided with a cutting edge, one end of the cutting edge is provided with a cutter ball head, and the cutting edge comprises an L20 curve arranged at the outer contour; this milling cutter of impeller is through setting up, and through the curve that cutting edge contour line L20 curve for the deflection fit out according to the impeller milling in-process, through setting up the cutter main part for straight shank tapering milling cutter, apply to compressor impeller's mass production, can effectively offset aluminium alloy material thin wall in mass processing and warp to promote the product quality, promote production efficiency and increase cutter life-span.
Description
Technical Field
The utility model relates to an impeller processing technology field specifically is a milling cutter of impeller.
Background
The tip of the impeller has great influence on the performance of the impeller, and the stress is great under the actual use condition; the geometric size of the blade tip is minimum, so the processing quality of the blade tip of the impeller is particularly important; at present, in impeller milling, particularly blade tip milling, cutting parameters are mainly reduced, the technical requirement of blade edge treatment of a cutter is improved, and the requirement of the blade tip area profile degree is met as much as possible, so that the requirement of milling machining of the impeller on the precision of the milling cutter is high.
The prior art has the following defects or problems:
in the mass production of the existing compressor impeller, the thin wall of an aluminum alloy material is easy to deform in the milling process of the mass impeller, so that the problems of poor quality of the processed product, low production efficiency and short service life of a cutter are caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's weak point, provide a milling cutter of impeller to reach and can effectively offset the aluminium alloy material thin wall and warp in the milling process of big impeller in batches, thereby promote the product quality, promote production efficiency and increase the purpose in cutter life-span.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a milling cutter of impeller, includes the cutter main part, cutter main part one end is provided with the handle of a knife, handle of a knife one end is provided with the cutting edge, cutting edge one end is provided with the cutter bulb, the cutting edge includes the L20 curve that outline department set up.
As the preferred technical scheme of the utility model, the cutter main part is straight shank tapering milling cutter.
As a preferable technical solution of the present invention, the L20 curve is an intersection line formed by the cutting edge and any axial cross section of the cutter body, and the L20 curve is a spline curve to which the deformation of the impeller milling material is simulated.
As the utility model discloses a preferred technical scheme, L20 curve is tangent with the cutter bulb, the rotatory arbitrary cross-sectional diameter of the entity that obtains of L20 curve place curve is greater than cutter bulb maximum diameter.
As the utility model discloses a preferred technical scheme, the rotatory arbitrary cross-sectional diameter of entity that obtains of L20 curve place curve increases gradually from a left side right side, finally with handle of a knife transition department connection.
Compared with the prior art, the utility model provides a milling cutter of impeller possesses following beneficial effect:
this milling cutter of impeller mills the curve that the deflection fit out of in-process for milling according to the impeller through cutting edge contour line L20 curve, is straight shank tapering milling cutter through setting up the cutter main part, applies to the mass production of compressor impeller, can effectively offset the aluminium alloy material thin wall in mass processing and warp to promote the product quality, promote production efficiency and increase cutter life-span.
