Abstract

The utility model discloses a vertical milling cutter with double edges for milling a through groove, comprising a cutter handle and a cutter body, wherein the cutter body consists of a spiral groove, a side edge, an end surface cutting edge and a chip removal groove. The vertical milling cutter is characterized in that the end surface cutting edge is arranged at the top of the cutter body, an inclination angle lambda s of the end surface cutting edge is equal to 3-8 degrees, the chip removal groove is arranged on the spiral groove adjoining to the center part of the end surface cutting edge, a front angle gamma 1 at the inner side of the end surface cutting edge is equal to 0-10 degrees, a front angle gamma 2 at the outer side of the end surface cutting edge is equal to 30 degrees, a back angle alpha 0 of the end surface cutting edge is equal to 12-15 degrees, and a spiral angle beta of the spiral groove is equal to 30 degrees. The vertical milling cutter is sharp in cutting edge, is smooth in chip removal, is high in processing efficiency, solves the problems of poor groove bottom quality and easiness in cutter breaking when an ordinary double-edge vertical milling cutter mills the through groove, and is suitable for processing various through grooves.

Description

The special-purpose slotting cutter of two sword grooves
Technical field
The utility model relates to a kind of slotting cutter, belongs to the cutter manufacturing technology field of mechanical processing industry, particularly the special-purpose slotting cutter of two sword grooves.
Background technology
The milling groove often adopts slotting cutter to accomplish.Two common sword tack slotting cutters, its face cutting edge is the straight cutting edge on helicla flute, not sharp and when cutting of cutting edge and workpiece contact-making surface are big; Chip removal is difficulty; So the often out-of-flatness of bottom land that mills out has tangible knife mark, tipping, breaking phenomenon also often occur.In order to overcome the deficiency of existing product, the two sword slotting cutters that development is fit to the groove Milling Process have practical meaning for production.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and a kind of tipping and breaking, stock-removing efficiency is high, chip removal is smooth and easy, the bottom land surface quality of processing is good two sword grooves special use slotting cutter of being difficult for is provided.
The technical problem that the utility model solved can adopt following technical scheme to realize:
The special-purpose slotting cutter of the utility model two sword grooves comprises handle of a knife and cutter hub, and said cutter hub is made up of helicla flute, side edge, face cutting edge and groove for cuttings, is characterized in: said face cutting edge is arranged on the top of cutter hub, the inclination angle λ of face cutting edge s=3 °~8 °; Said groove for cuttings is opened on the helicla flute near the face cutting edge centre, the anterior angle γ that said face cutting edge is inboard 1=0 °~10 °, the anterior angle γ in the face cutting edge outside 2=30 °, the relief angle α of face cutting edge 0=12 °~15 °, said spiral fluted helixangle=30 °.
The design feature of the special-purpose slotting cutter of the said two sword grooves of the utility model also is:
Said face cutting edge has two, and two face cutting edges are symmetricly set on the top of cutter hub.
Said groove for cuttings has two, and said two groove for cuttings are opened in respectively on the helicla flute near the centre of face cutting edge.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the inclination angle λ of the face cutting edge of the utility model s=3 °~8 °, make the outside of face cutting edge play main shear action; Through offering groove for cuttings, the anterior angle γ that face cutting edge is inboard 1=0 °~10 °; The anterior angle γ in the face cutting edge outside 2=30 °; The relief angle α of face cutting edge 0=12 °~15 °; Thereby face cutting edge is sharp, and chip removal is smooth and easy, and the bottom land surface quality of processing is good;
2, the milling cutter stock-removing efficiency of the utility model high, be difficult for breaking.
Description of drawings
Fig. 1 a is the structural representation of the special-purpose slotting cutter of two sword grooves;
Fig. 1 b is a face cutting edge portion enlarged drawing among Fig. 1 a;
Fig. 1 c is a building up by welding blade vertical view;
Fig. 2 is for being fit to the groove sketch map of the special-purpose slotting cutter processing of two sword grooves;
Label among the figure: 1 handle of a knife; 2 cutter hubs; 3 helicla flutes; 4 side edges; 5 face cutting edges; 6 groove for cuttings; 7 grooves; 8 workpiece.
The specific embodiment
Embodiment 1:
Shown in Fig. 1 a, Fig. 1 b and Fig. 1 c, present embodiment is the special-purpose slotting cutters of a kind of two sword grooves, processing groove 7 on workpiece 8.The special-purpose slotting cutter of two sword grooves comprises handle of a knife 1 and cutter hub 2, and cutter hub 2 is made up of helicla flute 3, side edge 4, face cutting edge 5 and groove for cuttings 6, and face cutting edge 5 is arranged on the top of cutter hub 2, the inclination angle λ of face cutting edge 5 s=3 °; Groove for cuttings 6 is opened on the helicla flute 3 near face cutting edge 5 centres, the anterior angle γ of face cutting edge 5 inboards 1=0 °, the anterior angle γ in face cutting edge 5 outsides 2=30 °, the relief angle α of face cutting edge 5 0=12 °, the helixangle of helicla flute 3=30 °.
Face cutting edge 5 has two, and is symmetricly set on the top of cutter hub.
Groove for cuttings 6 has two, and is opened in respectively on the helicla flute 3 near face cutting edge 5 centres.
The utility model has reasonably designed the structural parameters of face cutting edge 5, and cutting edge is sharp, chip removal is smooth and easy, and working (machining) efficiency is high, has solved the problem that common two sword slotting cutters are of poor quality at the bottom of milling groove time slot, be prone to breaking, is applicable to the processing of various grooves.
Embodiment 2:
The difference of present embodiment and embodiment 1 is: the inclination angle λ of face cutting edge 5 s=8 °; The anterior angle γ of face cutting edge 5 inboards 1=10 °, the relief angle α of face cutting edge 5 0=15 °.
The inclination angle of face cutting edge 5 is by λ sChange into λ for=3 ° s=8 °; Cutting edge sharpens, and processed bottom land is smooth, but edge strength weakens.The anterior angle of face cutting edge 5 inboards is by γ 1Change into γ for=0 ° 1=10 °, the relief angle of face cutting edge 5 is by α 0Change into α for=12 ° 0=15 °, make cutting edge sharpen, but intensity weaken.
Embodiment 3:
The difference of present embodiment and embodiment 1 is: the inclination angle λ of face cutting edge 5 s=5 °; The anterior angle γ of face cutting edge 5 inboards 1=5 °, the relief angle α of face cutting edge 5 0=13 °.
Adopt the slotting cutter of these group data, compare with the slotting cutter of embodiment 2 with embodiment 1, its cutting ability and service life are reasonable.
