Abstract
The utility model relates to a solid carbide single-blade gun drill. The solid carbide single-blade gun drill is composed of a tool bit, a tool bar, a drill neck and a tool handle. The tool bit is provided with a cutting part, and the cutting part comprises a second clearance angle of 30 degrees, a tool nose clearance angle of 38 degrees, an inner edge clearance angle of 30 degrees and an oiled face. The solid carbide single-blade gun drill has specific cutting angles for cutting machining, a set of cutting and cutter sharpening angle parameters are suitable for machining of parts made of a majority of materials, the solid carbide single-blade gun drill also has the advantages that chip breaking can be easily achieved and abrasion is little under the condition of high feeding rates, and the solid carbide single-blade gun drill has obvious effects of guaranteeing hole machining precision in various aspects.
Description
Technical field
The utility model relates to the deep hole machining technical field of tools, particularly a kind of whole hard alloy single-blade drill gun.
Background technology
Drill gun is a kind of cutter for deep hole machining at present, adds and uses man-hour a cutting edge to finish Cutting Parts.Its range of work is very wide, at die steel, glass fibre, plastics, even can both see his figure during the deep hole machining of high strength alloy steel.Require in the tighter deep hole machining in tolerance and surface roughness, drill gun can effectively guarantee dimensional accuracy, positional precision and the linearity in hole.
And reasonably cutting angle has more immediate influence for the precision in deep hole machining hole, may cause not chip breaking and finally causes the damage of drill gun as angle Selection is improper, causes the rising of the cost of charp tool; Or cause the part processing surface that cut is arranged, directly influence the surface roughness of part, cause the reduction of product percent of pass; Also can influence simultaneously the working (machining) efficiency of part, cause the decline of production capacity.
The applicant has obtained being applicable to the cutting angle of 0.5-4mm whole hard alloy single-blade drill gun machining use by the repetition test to this kind whole hard alloy single-blade drill gun cutting angle, for the every machining accuracy that guarantees the hole more significant effect is arranged.
The utility model content
The purpose of this utility model is to overcome the prior art deficiency, and provide a kind of whole hard alloy single-blade drill gun, this whole hard alloy single-blade drill gun has specific sharpening angle, mainly be suitable for processing the hole of diameter 0.5-4mm, this group sharpening angle parameter is applicable to the processing of most of material parts, still have easy chip breaking under the situation of high feeding, the little characteristics of wearing and tearing have more significant effect for the every machining accuracy that guarantees the hole.
The technical solution of the utility model: a kind of whole hard alloy single-blade drill gun, this whole hard alloy single-blade drill gun is made up of cutter head, knife bar, drill neck and handle of a knife, it is characterized in that, described cutter head has cutting tip, described cutting tip has second relief angle, point of a knife relief angle, interior edge clearance angle and crosses pasta, and wherein said described second relief angle is 30
0, described point of a knife relief angle is 38
0, described interior edge clearance angle is 30
0
Advantage of the present utility model and effect: according to the structural behaviour of whole hard alloy single-blade drill gun, by enforcement of the present utility model, this whole hard alloy single-blade drill gun has specific sharpening angle, mainly be suitable for processing the hole of diameter 0.5-4mm, this group sharpening angle parameter is applicable to the processing of most of material parts, still have easy chip breaking under the situation of high feeding, the little characteristics of wearing and tearing have more significant effect for the every machining accuracy that guarantees the hole.
Be described in more detail the utility model below by embodiment.
Description of drawings
Fig. 1 shows a kind of structural representation of whole hard alloy single-blade drill gun;
Fig. 2 shows a kind of schematic diagram of cutting tip of whole hard alloy single-blade drill gun;
Fig. 3 shows a kind of schematic diagram of sharpening angle of whole hard alloy single-blade drill gun cutting tip;
Concrete enforcement side
Further specify with the utility model of embodiment below in conjunction with accompanying drawing 1-3, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, there is shown a kind of structure of whole hard alloy single-blade drill gun, this welding single-blade drill gun is made up of cutter head 1, knife bar 2, drill neck 3 and handle of a knife 4, wherein cutter head 1 is generally whole hard alloy or steel steel knife body carbide inserts blade and sliver, 4 on knife bar 2, drill neck 3 and handle of a knife are made by the steel material, are connected in turn by soldering side between cutter head 1, knife bar 2, drill neck 3 and the handle of a knife 4 four and form whole hard alloy single-blade drill gun.
Through verifying and take all factors into consideration the structural behaviour of whole hard alloy single-blade drill gun repeatedly, we have found out one group of effective sharpening angle.This group angle mainly is suitable for processing the hole of diameter 0.5-4mm.This group angle parameter is applicable to the processing of most of material parts, still has easy chip breaking under the situation of high feeding, and the little characteristics of wearing and tearing have more significant effect for the every machining accuracy that guarantees the hole, below sharpening angle are described in conjunction with Fig. 2 and Fig. 3.
In conjunction with Fig. 2 and Fig. 3 as can be known, the cutter head cutting edge of the whole hard alloy single-blade drill gun of boring scope 0.5-4mm mainly comprises the second relief angle 1-1 shown in Figure 2, point of a knife relief angle 1-2, interior edge clearance angle 1-3 and crosses pasta 1-4, the angle of these 4 faces, with interior cutting edge 1-5, have correlation between the outer cutting edge 1-6, this several concrete angle requires as shown in Figure 3.
As can be seen from Figure 3, the second relief angle 1-1 is 30
0, point of a knife relief angle 1-2 is 38
0, interior edge clearance angle 1-3 is 30
0, this specific angle design makes whole hard alloy single-blade drill gun still have easy chip breaking under the situation of high feeding, the little characteristics of wearing and tearing have more significant effect for the every machining accuracy that guarantees the hole.
Whole hard alloy single-blade drill gun of the present utility model is not limited to the structure in above-described embodiment, can carry out multiple modification.In a word, all improvement in not breaking away from the utility model spirit scope all fall in the scope of the present utility model.
