Abstract
The utility model discloses a spline forming milling cutter which comprises a cutter body and blades, wherein the blades are arranged on the cutter body and uniformly distributed along the locating surface where the cutter body is located; and meanwhile, the cutter body is made by a hard alloy which is covered with at least one coating. The spline forming milling cutter is made the hard alloy instead of by conventionally used steel, meanwhile, the hard alloy is subjected to composite heat treatment and surface coating, and further, the blades are coated with special composite coatings, so that the whole spline milling cutter has extremely high shock resistance and wear resistance; and the spline milling cutter has a good use effect according to customers, and the production efficiency is greatly improved simultaneously.
Description
Technical Field
The utility model relates to a spline shaping milling cutter especially relates to a spline shaping milling cutter who is made by carbide, and it is applied to the processing of lathe trade or other machining trade integral key shafts.
Background
The traditional process of the spline shaft is to use a high-speed steel tool for processing, the cutting speed of the tool is low, the production efficiency is low, the service life of the tool is short, and users urgently need to have a better tool to replace a traditional processing method by adopting a better process, particularly for mass production of spline before grinding.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a satisfy customer's demand and solve above-mentioned technical problem, the design has developed a neotype spline shaping milling cutter, and its technical scheme who provides is:
a spline forming milling cutter, comprising: a cutter body and a blade;
the blades are arranged on the cutter body and are uniformly distributed along the positioning surface where the cutter body is arranged; meanwhile, the cutter body is made of hard alloy, and at least one coating is covered on the hard alloy.
Preferably, the cutter body is provided with a shaft hole at the center of the positioning surface, through which the spindle for rotating the milling cutter is inserted.
Preferably, the shaft hole is further provided with a positioning notch, and the shape of the positioning notch is matched with that of the positioning bulge on the mandrel.
Preferably, the cutter body is covered with two layers of coatings.
Preferably, the coating is a composite coating.
Preferably, the blade is covered with the composite coating.
Preferably, the blade teeth of the blade are trapezoidal or rectangular in shape.
Spline shaping milling cutter changed the steel that the tradition adopted often, the mode that has adopted carbide is made, carries out compound thermal treatment and surface coating simultaneously on this carbide, further be, also carried out special composite coating on the blade for whole spline milling cutter has very high impact resistance and wearability. The utility model provides a spline milling cutter is effectual after the customer uses, simultaneously by a wide margin improvement production efficiency.

Detailed Description
The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.
As shown in fig. 1-4, the utility model provides a spline shaping milling cutter, it includes: a cutter body 1 and a blade 2; the blades 2 are arranged on the cutter body 1 and are uniformly distributed along a positioning surface where the cutter body is arranged; meanwhile, the cutter body is made of hard alloy, and at least one coating is covered on the hard alloy. Here, the coating layer is a composite coating layer.
And the center of the positioning surface where the cutter body is positioned is provided with a shaft hole 3 which penetrates through a mandrel for the rotation of the milling cutter. And the shaft hole 3 is also provided with a positioning notch 301, and the shape of the positioning notch is matched with that of the positioning bulge on the mandrel.
Furthermore, the cutter body is covered with two layers of coatings.
In the present invention, it is preferable that the composite coating is also covered on the blade.
Preferably, the blade teeth of the blade are trapezoidal or rectangular in shape. Here, the shape of the insert may be determined according to the machining requirements of the part 4.
Spline shaping milling cutter changed the steel that the tradition adopted often, the mode that has adopted carbide is made, carries out compound thermal treatment and surface coating simultaneously on this carbide, further be, also carried out special composite coating on the blade for whole spline milling cutter has very high impact resistance and wearability. The utility model provides a spline milling cutter is effectual after the customer uses, simultaneously by a wide margin improvement production efficiency.
While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
