Abstract
The utility model relates to a threaded blade, and is used for inner thread lathing. The threaded blade comprises a blade body, a main cutting edge is fixed on the blade body, a rake face is arranged on the main cutting edge, the rake face is connected with the blade body through an arc-shaped face, the rake face is provided with a rake face included angle, and the arc-shaped face has a radius. The threaded blade is characterized in that the rake face included angle is 15.85 degrees to 16.15 degrees. The threaded blade is reasonable in structural design, the rake face included angle of the threaded blade is enlarged, scrap discharging effect is enhanced, the main cutting edge is prevented from being too hot in the process of machining because the scrap piles up, and therefore the main cutting edge is protected.
Description
Technical field
The utility model relates to a kind of screw thread blade, particularly relates to a kind of screw thread blade that is used for the car internal thread.
Background technology
The screw thread blade comprises cutter hub, is fixed with main cutting edge on the cutter hub, has rake face on the main cutting edge, and rake face links to each other with cutter hub through an arc surface, and rake face has the rake face angle, and arc surface has radius.The screw thread blade rake face angle that is used for the car internal thread of prior art is 13.85 °～14.15 °, and angle too small causes chip removal to have some setbacks, and chip is piled up easily and made that the main cutting edge temperature is too high, the main cutting edge easy fracture in process.
The utility model content
The utility model technical problem to be solved is to overcome deficiency of the prior art and a kind of screw thread blade is provided, reasonable in design, and chip removal is effective.
The technical scheme that the utility model solves the problems of the technologies described above employing is: a kind of screw thread blade; Comprise cutter hub, be fixed with main cutting edge on the cutter hub, have rake face on the main cutting edge; Rake face links to each other with cutter hub through an arc surface; Rake face has the rake face angle, and arc surface has radius, is characterised in that:
The angle of said rake face angle is 15.85 °～16.15 °.
The angle of the said rake face angle of the utility model is 16 °.
The radius of the said arc surface of the utility model is 0.7 millimeter～3.7 millimeters.
The utility model compared with prior art; Have following advantage and effect: reasonable in design, increased the angle of screw thread blade rake face angle, strengthened the chip removal effect; In process, prevent to make the main cutting edge temperature too high, protected main cutting edge because of talus accumulation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the side-looking structural representation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is described further.
Referring to Fig. 1 and Fig. 2, the utility model embodiment comprises cutter hub 1, is fixed with main cutting edge 2 on the cutter hub 1, and cutter hub 1 is as a whole with main cutting edge 2, is processed by carbide alloy.Have rake face 3 on the main cutting edge 2, rake face 3 links to each other with cutter hub 1 through an arc surface 4, and rake face 3 has the rake face angle, and arc surface 4 has radius R.
The rake face angle is claimed anterior angle again, and its angle is 15.85 °～16.15 °, and optimal angle is 16 °, and chip removal effect like this is optimum.
Arc surface 4 also plays the effect of chip removal, and its radius R is 0.7 millimeter～3.7 millimeters, and the chip removal effect is best in this scope.
