Abstract
The utility model discloses a ball-end milling cutter with two blades. The ball-end milling cutter with the two blades comprises a ball-end part and a cylinder/cone part, wherein the ball-end part comprises a ball blade which can pass through a ball center, a front cutter surface of the ball blade and a rear cutter surface of the ball blade, wherein the rear cutter surface of the ball blade comprises an arch-shaped curve surface I, an arch-shaped curve surface II and a concave curve surface which is positioned between the arch-shaped curve surface I and the arch-shaped curve surface II; the concave curve surface is respectively in smooth connection with the arch-shaped curve surface I and the arch-shaped curve surface II; the curvature of the arch-shaped curve surface I is larger than that of the arch-shaped curve surface II; the front cutter surface of the ball blade is concave; as the curvature of the arch-shaped curve surface I is larger than that of the arch-shaped curve surface II, the curve surface positioned between the arch-shaped curve surface I and the arch-shaped curve surface II is concave, and simultaneously the front cutter surface of the ball blade is concave, cuttings can be conveniently discharged when ball-end milling cutter with the two blades is used for cutting machining.
Description
Technical field
The utility model relates to a kind of two-edged rose cutter.
Background technology
Ball head knife is the cutter that is used for the various curved surfaces of milling, arc groove on the milling machine that is assemblied in of the similar bulb of blade.Rose cutter also is the R cutter, and rose cutter can milling mould steel, cast iron, carbon steel, steel alloy, tool steel, general iron material, belongs to slotting cutter.Usually rose cutter can be divided into two-edged rose cutter, three sword rose cutters according to the quantity of ball sword, and four sword rose cutters etc.Existing two-edged rose cutter is owing to ball sword rake face shape, and knife face is made of arc large curved surface usually behind the ball sword, and it exists cutting swarf to be difficult for the defective of discharging when carrying out machining.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of two-edged rose cutter of discharging cutting swarf that is beneficial to.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of two-edged rose cutter comprises bulb part and column part/tapered segment; Ball head point comprises ball sword, the ball sword rake face by the centre of sphere, and knife face behind the ball sword; Knife face is by arc curved surface one, arc curved surface two behind the ball sword, and the concave curvatures between arc curved surface one and arc curved surface two consists of; Concave curvatures and arc curved surface one, arc curved surface are in smoothing junction respectively; The curvature of arc curved surface one is greater than the curvature of arc curved surface two; The ball rake face is spill.
Preferably, the anterior angle of ball sword is 0.5 °～1.6 °.
Preferably, the relief angle one of ball sword is 11 °～2.5 °.
Preferably, the relief angle two of ball sword is 19 °～21 °.
By technique scheme, a kind of two-edged rose cutter provided by the utility model, ball head point comprise ball sword, the ball sword rake face by the centre of sphere, and knife face behind the ball sword; Knife face is by arc curved surface one, arc curved surface two behind the ball sword, and the concave curvatures between arc curved surface one and arc curved surface two consists of; Concave curvatures and arc curved surface one, arc curved surface are in smoothing junction respectively; Because the curvature of arc curved surface one is greater than the curvature of arc curved surface two, and the curved surface between arc curved surface one and arc curved surface two is concave curvatures; Simultaneously, because the ball rake face is spill, so this two-edged rose cutter has convenient advantage of discharging cutting swarf when carrying out machining.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the front view of the disclosed a kind of two-edged rose cutter of present embodiment;
Fig. 2 is the generalized section of A-A among Fig. 1;
Fig. 3 is the left view of the disclosed a kind of two-edged rose cutter of present embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of two-edged rose cutter, and with reference to figure 1, it comprises bulb part 1 and column part 2; Referring to figs. 2 and 3, bulb part 1 comprises ball sword 11, ball sword 11 rake faces 15, and ball sword 11 rear knife faces; Ball sword 11 rear knife faces are by arc curved surface 1, arc curved surface 2 14, and the concave curvatures between arc curved surface 1 and arc curved surface 2 14 13 consists of; Concave curvatures 13 and arc curved surface 1, respectively smooth connection of arc curved surface 2 14; The curvature of arc curved surface 1 is greater than the curvature of arc curved surface 2 14; Ball rake face 15 is spill; The anterior angle a of ball sword 11 is 0.5 °～1.6 °; Relief angle one b of ball sword 11 is 11 °～2.5 °; Relief angle two c of ball sword 11 are 19 °～21 °.
Can find out by technique scheme, a kind of two-edged rose cutter provided by the utility model, because the curvature of arc curved surface 1 is greater than the curvature of arc curved surface 2 14, and the curved surface between arc curved surface 1 and arc curved surface 2 14 is concave curvatures 13; Simultaneously, because ball rake face 15 is spill, so this two-edged rose cutter has convenient advantage of discharging cutting swarf.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
