Abstract
The invention provides a cutter for cutting machining of blade lug boss characteristics. The cutter is capable of solving easy-to-happen problems of long machining time, low machining efficiency, severe cutter wear, high production cost and low blade lug boss surface quality during the cutting machining of the blade lug boss characteristics by using a hard alloy ball-end cutter at present. The cutter is a large-angle taper cutter, and comprises a lateral conical surface and a bottom R1 angle, the two of which are in smooth transition and integrally connected with each other; the bottom R1 angle is consistent with an R2 angle of each blade lug boss characteristic to be machined in dimension; and the lateral conical surface is a cutting edge of the cutter.
Description
Technical field
The present invention relates to the Tool Design field of blade machining, be specially the cutter for blade boss feature machining.
Background technology
Blade boss is characterized as space three-dimensional curved portion, and because its curved surface features is comparatively complicated, therefore the boss feature of blade mould forging blank is more relative to profile surplus and uneven.For meeting the finished size of boss feature, existing processing mode mainly adopts carbide alloy bulb cutter to carry out copying to blade boss feature, although this machining mode can cut the boss feature of various blade preferably, but because the blank allowance of boss feature is large, cutter rail is fine and close, and the low meeting of tool sharpening parameter at boss position causes the long processing time of boss feature; In addition, because carbide alloy bulb cutter and boss feature machining surface are point cantact, its cutting parameter is low, and tool wear is serious, and need to carry out reconditioning to cutter continually and even change, thus cause the cost of charp tool significantly to increase, production cost is high; In addition, also easily occur burning cutter phenomenon adding the heavy wear of man-hour due to cutter to blade boss feature, thus have a strong impact on blade boss figuratrix crudy.
Summary of the invention
For the problems referred to above, the invention provides the cutter for blade boss feature machining, its can solve easily occur when adopting at present carbide alloy bulb cutter to carry out machining to blade boss feature long processing time, working (machining) efficiency is low, tool wear is serious, production cost is high and the low-quality problem of blade boss surface.
For the cutter of blade boss feature machining, it is characterized in that: it is wide-angle tapering cutter, it comprises sidepiece taper seat and R1 angle, bottom, described sidepiece taper seat and R1 angle, bottom smoothly transit and connect into entirety, R1 angle, described bottom is consistent with the R2 angle angle of blade boss feature to be processed, and described sidepiece taper seat is Tool in Cutting sword.
Further, the tapering of described sidepiece taper seat is 15 °.
Further, the surface spraying of described sidepiece taper seat has titanium nitride coating.
Compared with existing carbide alloy bulb cutter, beneficial effect of the present invention is: it is using sidepiece taper seat as cutting edge, thus can effectively increase cutter and contact area processed by blade boss, tool sharpening parameter promotes obviously, effectively reduce the wearing and tearing to cutter, thus effectively reduce process time, the raising working (machining) efficiency of boss feature, and greatly can improve blade boss surface quality; In addition, it is consistent by angle is arranged at R1 angle, bottom and the R2 angle of blade boss feature to be processed, both the pivot angle of machine tool chief axis in processing had been reduced, improve the qualification rate of program composition, also shorten cutter Len req, improve the stability of process tool while such cutting-tool's used life gets a promotion, the surface quality of boss feature have also been obtained and further ensures.
Accompanying drawing explanation
Fig. 1 is blade boss feature schematic diagram to be processed;
Fig. 2 is the structural representation of the present invention for the cutter of blade boss feature machining.
Detailed description of the invention
See Fig. 2, for the cutter 10 of blade boss feature machining, it is wide-angle tapering cutter, it comprises sidepiece taper seat 11 and R1 angle, bottom, sidepiece taper seat 11 and R1 angle, bottom smoothly transit and connect into entirety, R1 angle, bottom is consistent with the R2 angle angle of blade boss feature to be processed, and sidepiece taper seat is Tool in Cutting sword; The tapering α of sidepiece taper seat 11 is 15 °; The surface spraying of sidepiece taper seat 11 has coating titanium nitride coating, thus greatly can improve the wearability of cutter, and therefore after each cutter grinding, machinable blade quantity increases greatly, also effectively can reduce the cost of charp tool.After adopting cutter of the present invention, process contact area due to cutter and blade boss greatly to increase, thus program efficiency promotes more than 60%, single reconditioning machining blade quantity can be promoted to existing more than 30 by 2 of former cutter, and the surface quality of boss also significantly promotes.
In Fig. 1,1 is blade, and 2 is blade boss.
Claims (3)
1. for the cutter of blade boss feature machining, it is characterized in that: it is wide-angle tapering cutter, it comprises sidepiece taper seat and R1 angle, bottom, described sidepiece taper seat and R1 angle, bottom smoothly transit and connect into entirety, R1 angle, described bottom is consistent with the R2 angle angle of blade boss feature to be processed, and described sidepiece taper seat is Tool in Cutting sword.
2. the cutter for blade boss feature machining according to claim 1, is characterized in that: the tapering of described sidepiece taper seat is 15 °.
