Abstract
The utility model discloses a special vertical milling cutter for a single-blade forming V-shaped groove. The special vertical milling cutter comprises a cutter handle and a cutter body, wherein the cutter body consists of a first cutting edge, a second cutting edge, chip removal grooves and spiral grooves. The special vertical milling cutter is characterized in that the first cutting edge and the second cutting edge are in an unsymmetric structure, the cutting edge angle lambda s of the first cutting edge is 15-45 degrees, the cutting edge angle of the second cutting edge is 2-6 degrees smaller than that of the first cutting edge, anterior angles gamma 0 of the first cutting edge and the second cutting edge are 5-10 degrees, posterior angles alpha 0 of the first cutting edge and the second cutting edge are 12-15 degrees, the spiral angle of each spiral groove is 30 degrees, and the two chip removal grooves are respectively arranged on the spiral grooves which are close to the first cutting edge and the second cutting edge. According to the special vertical milling cutter disclosed by the utility model, the cutting edges are sharp, chip is smooth to remove, and the cutting resistance is small, so that the phenomena of cutter flaking and breaking are greatly reduced; and in addition, the processed V-shaped groove is symmetric, and the surface quality of the V-shaped groove is good, so that the V-shaped groove is milled with high efficiency, high quality and high accuracy.
Description
Technical field
The utility model relates to a kind of slotting cutter, is applicable to the processing of " V " type groove, belongs to the cutter manufacturing technology field of mechanical processing industry.
Background technology
Milling Process is a kind of processing method commonly used in the machining, and slotting cutter is the most frequently used milling cutter.Can only be one of difficult point of Milling Process with " V " type groove of slotting cutter processing.Two sword symmetrical structures, the cutting blade angle λ of two cutting edges on the slotting cutter are adopted in the slotting cutter cutting edge design of general processing " V " type groove usually
sBe identical, two cutting edges are worked simultaneously in process, and cutting resistance is bigger, occurs tipping, breaking easily, and processed " V " type notch is prone to produce flange, burr.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, provides a kind of working (machining) efficiency single-blade moulding " V " type groove high, that be difficult for tipping, breaking special-purpose slotting cutter, and " V " type groove of this slotting cutter processing is symmetrical, surface quality is good.
The utility model adopts following technical scheme to realize for the technical problem that solves:
The special-purpose slotting cutter of the utility model single-blade moulding " V " type groove; Comprise: handle of a knife and cutter hub; Said cutter hub is made up of first cutting edge, second cutting edge, groove for cuttings and helicla flute; Be characterized in: first cutting edge and second cutting edge are designed to two sword dissymmetrical structures, the cutting blade angle λ of said first cutting edge
sBe 15 °～45 °, the cutting blade angle of second cutting edge is less than the cutting blade angle of first cutting edge, and difference is 2 °～6 °, the anterior angle γ of first cutting edge and second cutting edge
0Be 5 °～10 °, relief angle α
0Be 12 °～15 °, the spiral fluted helixangle is 30 °.
Described groove for cuttings has two, is separately positioned on the helicla flute near first cutting edge and second cutting edge.
Compared with present technology, the effect that the utility model is useful is embodied in:
1, the utility model adopts two sword dissymmetrical structures, and the cutting edge that plays the final molding effect only has one, adds man-hour first cutting edge and plays the cutting forming effect; The cutting blade angle of second cutting edge is less than the cutting blade angle of first cutting edge, and difference is 2 °～6 °, and the second cutting edge work in-process plays the assisted machining effect; " V " type groove symmetry of being processed is good.
2, in the utility model because the anterior angle γ of first cutting edge and second cutting edge
0Be 5 °～10 °, relief angle α
0Be 12 °～15 °, make that cutting edge is sharp, cutting resistance is little, between main cutting edge and helicla flute, be provided with groove for cuttings simultaneously, make chip removal smooth and easy, significantly reduced tipping, breaking phenomenon generation.
3, in the utility model because the cutting blade angle λ of first cutting edge
sBe 15 °～45 °, machinable " V " type groove scope is wide, and " V " type groove angle angle is 30 °～90 °.

Fig. 2 is for being fit to " V " type groove sketch map that the special-purpose slotting cutter of the utility model single-blade moulding " V " type groove is processed on workpiece;
Label among the figure: 1 handle of a knife; 2 cutter hubs; 3 helicla flutes; 4 groove for cuttings; 5 second cutting edges; 6 first cutting edges; 7 " V " type groove; 8 workpiece.
The specific embodiment
Embodiment 1:
As shown in Figure 1, present embodiment is the special-purpose slotting cutter of a kind of single-blade moulding " V " type groove, and processing " V " type groove 7 angle angles are 30 ° on workpiece 8.The special-purpose slotting cutter of this single-blade moulding " V " type groove; Comprise: handle of a knife 1 and cutter hub 2; Cutter hub 2 is made up of first cutting edge 6, second cutting edge 5, groove for cuttings 4 and helicla flute 3; Be characterized in: first cutting edge 6 and second cutting edge 5 are designed to two sword dissymmetrical structures, the cutting blade angle λ of first cutting edge
sBe 15 °, the cutting blade angle of second cutting edge 5 is less than the cutting blade angle of first cutting edge 6, and difference is 2 °, the anterior angle γ of first cutting edge 6 and second cutting edge 5
0Be 5 °, relief angle α
0Be 12 °, the spiral fluted helixangle is 30 °.
In the present embodiment, groove for cuttings 4 has two, is separately positioned on the helicla flute 3 near first cutting edge 6 and second cutting edge 5.
During work, the milling cutter rotation, lathe is done at the uniform velocity feed motion simultaneously, and second cutting edge 5 and first cutting edge 6 cutting workpiece 8, the second cutting edges 5 successively play the assisted machining effect, and first cutting edge 6 plays last moulding effect to " V " type groove.Therefore " V " type groove of being processed is symmetry fully; First cutting edge 6 and second cutting edge, 5 angle with rational parameters have improved stock-removing efficiency, have reduced cutting resistance, have prevented processed " V " type notch flange, the generation of burr effectively, groove for cuttings 4 is set is beneficial to chip removal; Therefore the utility model can be realized efficient, high-quality, the high accuracy milling of " V " type groove.
Embodiment 2:
The difference of present embodiment and embodiment 1 is: processing " V " type groove 7 angle angles are 90 °, the cutting blade angle λ of first cutting edge
sBe 45 °, the cutting blade angle of second cutting edge 5 is less than the cutting blade angle of first cutting edge 6, and difference is 6 °, the anterior angle γ of first cutting edge 6 and second cutting edge 5
0Be 10 °, relief angle α
0It is 15 °.
