Abstract
The utility model provides a micropore drill bit of processing spinneret, it includes clamping part, transition portion and work portion, work portion is including the side that connects gradually no. 1, side no. 2, side no. 3 and side no. 4, side no. 1 and three symmetries of side, and side no. 2 and four symmetries of side, the isosceles trapezoid of longitudinal section shape for invering of side no. 1 and side no. 3, the longitudinal section shape of side no. 2 and side no. 4 is the rectangle, the center on the base of side no. 2 and side no. 4 is respectively to milling the cutting edge that forms two triangle -shaped in the side slant, the hypotenuse contained angle of two cutting edges is 100. The cutting edge mills the material under high -speed rotation, mills the spinneret orifice precision height that, has guaranteed the rounding degree of round hole.
Description
Technical field
The utility model relates to spinneret manufacturing, particularly a kind of micropore drill bit.
Background technology
In spinneret, the outlet of spinneret orifice is less, and the diameter of circular hole is generally between 0.2-0.3mm.The outlet of current processing spinneret orifice mainly adopts the circular bite of carbide alloy, but the roundness of circular hole that this kind of drill bit processes is poor, follow-up finishing can only be relied on to ensure yields, waste time and energy.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is the micropore drill bit providing a kind of result of use good, to ensure the roundness of die orifice exit.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of micropore drill bit, comprise the body of pencil shape, described body comprises clamping part, transition part and operate portions; Described operate portions comprise connect successively side one, side two, side three and side four, described side one is symmetrical with described side three, described side two is symmetrical with described side four, the vertical sectional shape of described side one and side three is inverted isosceles trapezoid, and the vertical sectional shape of described side two and side four is rectangle; The center on the base of described side two and side four forms two leg-of-mutton blades respectively to side milling obliquely, and the hypotenuse angle of two described blades is 100 °.
Preferably, the length of described operate portions is 1.0mm.
Preferably, described transition part is inverted taper, and its tapering is 40 °.
By technique scheme, the micropore drill bit that the utility model provides, its operationally, the blade of bottom carries out milling to material under High Rotation Speed, and the spinneret orifice precision milled out is high, ensure that the roundness of circular hole.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 and 2 is the side view of a kind of micropore drill bit disclosed in the utility model embodiment;
Fig. 3 is the structural representation of the operate portions disclosed in the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figures 1 to 3, a kind of micropore drill bit, comprises the body of pencil shape, and body comprises clamping part a, transition part b and operate portions c; Operate portions comprise connect successively side one, side two, side three and side four, side one is symmetrical with side three, side two is symmetrical with side four, and the vertical sectional shape of side one and side three is inverted isosceles trapezoid, and the vertical sectional shape of side two and side four is rectangle; The center on the base of side two and side four forms two leg-of-mutton blade d respectively to side milling obliquely, and the hypotenuse angle of two blades is 100 °.
Wherein, the length of operate portions c is 1.0mm.
Transition part b is inverted taper, and its tapering is 40 °.
The micropore drill bit that the utility model provides, its operationally, the blade of bottom carries out milling to material under High Rotation Speed, and the spinneret orifice precision milled out is high, ensure that the roundness of circular hole.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (3)
