Abstract
The utility model relates to a novel chamfering cutter. The novel chamfering cutter comprises a cutter bar, a radial cutter head is formed at one end of the cutter bar through extending along the radial edge of the cutter bar, a chamfering blade is arranged on the peripheral surface of the radial cutter head, a first cutting edge and a second cutting edge which are formed through being recessed towards the inner side of the chamfering blade are arranged on the outer side surface of the chamfering blade, one end of the first cutting edge is connected with one end of the second cutting edge, an inclined angle which is formed between the first cutting edge and the axial direction of the radial cutter head is 29.9 degrees to 30.1 degrees, and an inclined angle which is formed between the second cutting edge and the axial direction of the radial cutter head is 12.9 to 13.1 degrees. The novel chamfering cutter has the beneficial effects of high processing precision and capability of rapidly discharging chips.
Description
Technical field
The utility model relates to a kind of novel chamfering tool.
Background technology
In prior art, engineering plastics are punched or when chamfering, mostly adopt common drill bit or lathe tool, but adopt hole or the chamfering that common drill bit or lathe tool process conventionally can leave the ugly marking at surface to be machined, when the engineering plastics of this external processing high-hardness, tool wear is rapid; On the other hand, because the temperature of cutting zone is higher, and plastics or resin material itself is just difficult for heat radiation, therefore has part cutting swarf to melt, and is bonded on the rake face of cutter, and cutting swarf is also easily blocked in discharge groove, and is not easy rapid discharge.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of machining accuracy the high and quick novel chamfering tool of chip removal.
The technical scheme solving the problems of the technologies described above is as follows:
Novel chamfering tool, comprise knife bar, one end of knife bar radially extends to form a radially cutterhead along it, radially on the periphery of cutterhead, be provided with chamfering blade at this, the lateral surface of this chamfering blade is provided with to recessed the first cutting edge and the second cutting edge inside this chamfering blade, one end of the first cutting edge is connected with one end of the second cutting edge, the first cutting edge and radially cutter axis are 30 ± 0.1 ° to formed angle, and the second cutting edge and radially cutter axis are 13 ± 0.1 ° to formed angle.
The medial surface of described chamfering blade is provided with U-shaped groove, after radially the circumference of cutterhead is inserted in the U-shaped groove of chamfering blade and chamfering cutterhead be welded and fixed and be integrated.
The upper surface of chamfering blade and the radially spacing between cutterhead upper surface are 0.5mm, and the lower surface of chamfering blade and the radially spacing between cutterhead lower surface are 1mm.
The lower surface of chamfering blade and the radially cutterhead angle between is radially 1 °.
Adopted such scheme, chamfering blade of the present utility model is alloy blade, has extraordinary wearability and heat resistance, and finished surface is bright and clean, fine and smooth, thereby improves the machining accuracy of cutter.The first cutting edge and radially cutter axis are 30 ° ± 0.1 ° to formed angle, and the second cutting edge and radially cutter axis are 13 ° ± 0.1 ° to formed angle, and cooperatively interacting of two cutting edges can be cut fast.The upper surface of chamfering blade and the radially spacing between cutterhead upper surface are 0.5mm, and the lower surface of chamfering blade and the radially spacing between cutterhead lower surface are 1mm.This structure, for the chip cutting out provides a kind of passage of circulation, makes chip removal smooth and easy.
Accompanying drawing explanation
Fig. 1 is the front view of novel chamfering tool of the present utility model;
Fig. 2 is the A portion enlarged drawing of Fig. 1;
In figure, 1 is knife bar, and 2 is cutterhead radially, and 3 is chamfering blade, and 4 is the first cutting edge, and 5 is the second cutting edge.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
See figures.1.and.2, novel chamfering tool of the present utility model, comprises knife bar 1, and one end of knife bar radially extends to form a radially cutterhead 2 along it, radially on the periphery of cutterhead, is provided with chamfering blade 3 at this.The medial surface of described chamfering blade is provided with U-shaped groove, after radially the circumference of cutterhead 2 is inserted in the U-shaped groove of chamfering blade 3 and chamfering cutterhead be welded and fixed and be integrated.The upper surface of chamfering blade 3 and radially the spacing L1 between cutterhead upper surface are 0.5mm, and the lower surface of chamfering blade and radially the spacing L2 between cutterhead lower surface are 1mm.The lower surface of chamfering blade and the radially cutterhead angle a between is radially 1 °.The lateral surface of chamfering blade is provided with recessed rear formation the first cutting edge 4 in inner side and the second cutting edge 5 to this chamfering blade, one end of the first cutting edge 4 is connected with one end of the second cutting edge 5, the first cutting edge 4 and radially cutter axis are 30 ° ± 0.1 ° to formed angle b, and the second cutting edge 5 and radially cutter axis are 13 ° ± 0.1 ° to formed angle c.
