Described twice spiral cutting sword the first cutting edge extends to the cutter head front end face point of a knife that crosses that to form diameter be 0.2mm, and the helical angle of spiral cutting sword is 30 °.
Described cutter head length (l) is 2.25mm, and cylindrical knife centriciput diameter is 2.97mm, and truncated cone-shaped cutter head rear portion and cutter neck abutted surface diameter are 1.8mm, and conical cutter head front cone angle is 90 °, and the cone angle of place, truncated cone-shaped cutter head rear portion circular cone is 90 °.
Described cutter neck diameter is 1.1mm, and cutter neck length degree (l ') be 3.35mm, cutter neck and handle of a knife joint are provided with chamfering, and chamfer angle is 60 °.
Described twolip forming cutter overall length (L) is 50mm, and handle of a knife diameter is 4mm.
On described cutter head, be provided with spiral cutting sword relative position place the spiral bit-withdrawing slot matching with spiral cutting sword.
The beneficial effects of the utility model are: adopt such scheme, this twolip forming cutter can be by the disposable machine-shaping of less shape with groove structure more complicated Al-alloy products, not tool changing, the stability of converted products is high, high conformity, has improved production efficiency, has reduced production cost.The spiral cutting sword being made up of first, second, third cutting edge and transition cutting edge can carry out disposable machining to baroque groove in conjunction with the specific shape of cutter head, the diameter of truncated cone-shaped cutter head rear portion and cutter neck abutted surface is less than cutter neck diameter, such setting is beneficial to chip removal, contribute to improve machining accuracy and surface quality, and utilize first, second cutting edge of this twolip forming cutter to carry out machining to the surface of Al-alloy products, sidewall.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the enlarged drawing of I portion in Fig. 1.
In figure: 1 is handle of a knife, 2 is that cutter neck, 3 is cutter head, and 3.1 is cutter head front portion, and 3.2 is cutter head rear portion, and 3.3 is cutter head middle part, and 3.4 is point of a knife, and 4 is spiral cutting sword, and 4.1 is the first cutting edge, and 4.2 is the second cutting edge, and 4.3 is the 3rd cutting edge, and 4.4 is transition cutting edge.
Detailed description of the invention
As Fig. 1, twolip forming cutter shown in Fig. 2, comprise handle of a knife 1, cutter head 3 and the cutter neck 2 that is connected handle of a knife 1 and cutter head 3, the cross section of cutter head 3 is spindle, cutter head 3 is by conical cutter head front portion 3.1, truncated cone-shaped cutter head rear portion 3.2 and cylindrical knife centriciput 3.3 form, one end that cutter neck 2 and truncated cone-shaped cutter head rear portion 3.2 diameters are less joins, cutter head 3 is provided with twice spiral cutting sword 4, spiral cutting sword 4 is by the first cutting edge 4.1 that is located at anterior 3.1 taper seats of cutter head, be located at the second cutting edge 4.2 of 3.3 sides, cutter head middle part, being located at cutter neck 2 forms with the transition cutting edge 4.4 that is located at the cutter head rear portion 3.2 round platform conical surfaces with the 3rd cutting edge 4.3 of cutter head rear portion 3.2 abutted surfaces, the first cutting edge 4.1 of twice spiral cutting sword 4 extends to anterior 3.1 end faces of cutter head and crosses and form the point of a knife 3.4 that diameter d is 0.2mm, the helical angle of preferred spiral cutting sword 4 is 30 °, on cutter head 3, be provided with spiral cutting sword 4 relative position places the spiral bit-withdrawing slot matching with spiral cutting sword 4, preferred cutter head 3 length (l) are 2.25mm, cylindrical knife centriciput 3.3 diameters are 2.97mm, truncated cone-shaped cutter head rear portion 3.2 is 1.8mm with cutter neck 2 abutted surface diameters, the anterior 3.1 cone angle r1 of conical cutter head are 90 °, the cone angle r2 of truncated cone-shaped cutter head rear portion 3.2 place circular cones is 90 °, the one machine-shaping of this twolip forming cutter or welding fabrication, material is wolfram steel, in conjunction with production cost and when cutting satisfied mechanical property etc. consider, preferred this twolip forming cutter overall length L is 50mm, handle of a knife 1 diameter is 4mm, handle of a knife 1 is 60 ° of chamfering r3 with cutter neck 2 joints, cutter neck 2 diameters are 1.1mm, less cutter head 3 sizes of this twolip forming cutter are in conjunction with the shape of cutter head 3 and formation and the distribution of spiral cutting sword 4, can carry out disposable machining to the less Al-alloy products with complex groove structure, and ensure machining accuracy, cutter neck 2 length l ' be 3.35mm, truncated cone-shaped cutter head rear portion 3.2 is less than cutter neck 2 diameters with the diameter of cutter neck 2 abutted surfaces, such setting is beneficial to chip removal, contribute to improve machining accuracy and surface quality, the first cutting edge 4.1 of twice spiral cutting sword 4, the second cutting edge 4.2 can also be to the surface of Al-alloy products, sidewall carries out machining, and first cutting edge 4.1 extend to cross point of a knife 3.4 that the diameter d that forms is 0.2mm of anterior 3.1 end faces of cutter head and in the time of longitudinal incision, there is Self-centering Action, can also be to carry out hole processing or degree of depth Carving Machining compared with small workpiece, applicability is wide, overcome existing cutter to less compared with the low precision of complex part machining, an inefficient difficult problem, during separately according to milling Al-alloy parts, cutting speed should not be too high, cutter should be selected the feature of gap serrated knife, while comprehensively longitudinally incision, sword number is fewer again, the factors such as longitudinal cutting-in performance is better, therefore this forming cutter is designed to twolip.
