Description
Technical Field
The utility model relates to a gear machining tool, in particular to an optimized gear rough milling cutter blade.
Background
Currently, with the rapid development of the wind power industry, efficient gear milling machines are more and more, so that the application of indexable gear milling cutters is very popular, particularly the application of rough milling cutters is more popular, and the production and the manufacture of indexable gear milling cutters in China are also more than 20 years, wherein the indexable gear rough milling cutters manufactured in production are the most, and the size of side edge blades of the rough milling cutters is basically (length x width x thickness): 19.05x14.3x6.35, 15.88x15.88x7.94 and 12.7x12.7x6.35, wherein the size of 12.7x12.7x6.35 is most widely applied, most of traditional rough milling cutters are arranged in a mode of combining a top tooth belt circular arc cutter blade and a side tooth square cutter blade, the top tooth circular arc cutter blade is four-time rotated, the side tooth square cutter blade is eight-time rotated, the cost performance of the side tooth cutter blade of the cutter head is very high, the use and management cost of the cutter blade of a user are saved, the requirements on rough milling cutters are gradually mature and wide due to the annual rapid growth of processing equipment in recent years, the requirements on the rough milling cutters are also higher and higher, the cutting speed, the vibration, the noise and the like of the rough milling cutters are also higher, therefore, a plurality of cutter manufacturers develop a plurality of side tooth-based special-shaped belt front angle cutter blades successively, the original cutter head cannot be used again, and the cutter head is difficult to manufacture due to the fact that the problems existing above are solved, and the new design cutter head is very high in general manufacturing cost. Therefore, there is an urgent need to develop a blade that can meet the above-mentioned requirements.
Disclosure of Invention
The utility model provides an optimized gear rough milling cutter blade, which solves the problems of high processing noise, low cutting efficiency, high cutting load and difficult user efficiency improvement of the existing blade, and the specific technical scheme for solving the problems is as follows:
the utility model relates to an optimized gear rough milling cutter blade, which is directly processed by a finished blade of the existing indexable cemented carbide toothed side blade, and can also be used for reprocessing a new blade, wherein a bevel plane with the height of h and the angle of alpha is designed at the side cutting edge of the indexable cemented carbide toothed side blade, and the middle part positioning plane of the existing indexable cemented carbide toothed side blade is reserved to form an axial positive rake angle for cutter disc processing, and the axial positive rake angle is the same as the cutter groove positioning plane of the existing cutter disc, so that the novel indexable cemented carbide toothed side blade can be placed in the cutter groove of the existing cutter disc.
The optimized high-efficiency gear rough milling cutter blade can be used for machining a new blade, and can also be directly machined by a finished blade of the existing indexable hard alloy toothed side blade, and the cutting edge of the blade is machined into an inclined plane with the height of h and the angle of alpha, so that the gear rough milling cutter has the advantages of improving the cutting speed, reducing noise, being light and rapid in cutting, not wasting the existing cutterhead, improving the production efficiency and saving the cost due to the fact that the inclined plane with the height of h and the angle of alpha is machined on the side edge part of the blade.
