Abstract
The utility model discloses a kind of hard alloy bar, comprising: bar body, through the inner passage of bar body, inner passage is curved channel.The utility model provides a kind of curved channel be provided with through bar body, also can reach good cooling-down effect in the inside of bar, thus such bar cutting effect is good, and wear-resisting property is good, increases working life.
Description
Technical field
A kind of bar, particularly a kind of hard alloy bar.
Background technique
Traditional cemented carbide pole, is solid bar, after being processed into drill bit with it, can only cool outside when operative workpiece, the effect that cannot reach cooling in its heart portion, cause its cutting effect poor, wear resistance decrease, working life is low, and prior art is unresolved such problem also.
Model utility content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of curved channel be provided with through bar body, also can reach good cooling-down effect in the inside of bar, thus such bar cutting effect is good, wear-resisting property is good, increases working life.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
Hard alloy bar, comprising: bar body, and through the inner passage of bar body, inner passage is curved channel.
Aforesaid hard alloy bar, inner passage has many, and many inner passages are intersected intersection point; The curvature of curved channel is 30 degree.
Aforesaid hard alloy bar, intersection point is multiple.
Aforesaid hard alloy bar, the central shaft of multiple inner passage overlaps.
Aforesaid hard alloy bar, the central shaft of inner passage overlaps with the central shaft of bar body.
Aforesaid hard alloy bar, inner passage has two, and two inner passages are intersected 5 intersection points.
Usefulness of the present utility model is: the utility model provides a kind of curved channel be provided with through bar body, also good cooling-down effect can be reached in the inside of bar, thus such bar cutting effect is good, wear-resisting property is good, increases working life.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of embodiment of the present utility model;
Fig. 2 is the side view of a kind of embodiment of the present utility model;
The implication of reference character in figure:
1 inner passage, 2 bar bodies, 3 intersection points, 4 central shafts.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
Hard alloy bar, comprising: bar body 2, and through the inner passage 1 of bar body 2, inner passage 1 is curved channel.Inner passage 1 is designed to curve, and the design of curve increases the area of contact of condensable product and bar body 2, and the heat of bar body 2 can be taken out of uniformly; In order to can farthest be taken out of fast by even heat, the curvature of curved channel is 30 degree.
Inner passage 1 has many, and many inner passages 1 are intersected intersection point 3, and intersection point 3 is multiple; The central shaft 4 of multiple inner passage 1 overlaps; The central shaft 4 of inner passage 1 overlaps with the central shaft 4 of bar body 2; An overall formation spirality; The longitudinal section of inner passage 1 is circular.
As shown in the figure, preferred as one, inner passage 1 has two, and two inner passages 1 are intersected 5 intersection points 3.
The utility model provides a kind of curved channel be provided with through bar body 2, also can reach good cooling-down effect in the inside of bar, thus such bar cutting effect is good, and wear-resisting property is good, increases working life.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, the technological scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection domain of the present utility model.
