Abstract
The utility model provides a hard alloy blade welded stair-step molding spade drill for a titanium alloy. The hard alloy blade welded stair-step molding spade drill for the titanium alloy comprises a hard alloy blade and a cutter body. The cutter body is composed of an edge part and a tail handle. A concave groove is arranged at the front end of the cutter body along the radial direction. The hard alloy blade is embedded in the concave groove at the front end of the cutter body and is in a stair-step shape. A main oil gallery is arranged inside the cutter body along the axial direction. The front end of the main oil gallery is communicated with a plurality of subsidiary oil galleries which are communicated with the outside of the cutter body. Each of the plurality of subsidiary oil galleries inclines towards the front end of the cutter body and an angle is formed between the center axis of the cutter body and each of the plurality of subsidiary oil galleries. The hard alloy blade welded stair-step molding spade drill for the titanium alloy is formed by combining separated parts, thereby resolving the problem that an existing integral type spade drill cutter is too high in cost.
Description
Technical field
The utility model relates to a kind of chit drill, and particularly a kind of titanium alloy is with welding the carbide chip stepped flat drill.
Background technology
Titanium alloy can not only carry out high-speed cutting to common steel with weldering carbide chip cutter, and can process various non-ferrous metals and hard brittle material, such as hardened steel, high temperature alloy, hard rubber, glass and marble etc., uses more extensive at aviation field.
In aviation field, often want ream to go out different nests, so just need the chit drill of different size.Available technology adopting be the monoblock type chit drill, its tool sharpening is difficulty not only, and processing cost is too high.
Summary of the invention
The purpose of this utility model provides a kind of titanium alloy with weldering carbide chip stepped flat drill, adopts Split assembled to form, and has solved the too high difficult problem of the existing monoblock type chit drill cost of charp tool.
The technical solution of the utility model: titanium alloy is with welding the carbide chip stepped flat drill, comprise carbide chip and cutter hub, cutter hub is comprised of blade and caudal peduncle, front end edge at cutter hub radially has a groove, carbide chip is embedded in the groove of cutter hub front end, and carbide chip is stepped.
Inside at cutter hub is provided with main oil gallery vertically, and the front end of main oil gallery is communicated with several minutes oil duct, and a minute oil duct communicates with the cutter hub external world, minute oil duct to the front end of cutter hub tilt and with the central axis formation angle of cutter hub.
The beneficial effects of the utility model: this titanium alloy can process different diameter nests simultaneously with weldering carbide chip stepped flat drill on titanium alloy material, the situation of skidding, not considering to be worth doing down can not occur; Carbide chip is embedded in the groove of cutter hub front end, plays the effect of fixed blade by the mode of welding; Because cooling structure in adopting can well reduce the temperature in the process, save the cost of charp tool, improve working (machining) efficiency.
