Abstract
The utility model discloses a kind of drill bit, comprise drill body, chisel edge, chip area, chip pocket and arc surface, described drill body and apex point center are provided with the chisel edge of 50 ~ 55 degree, described chisel edge both sides are provided with chip pocket, described chip pocket terminal is 70 degree and is domaticly connected with chip area, described arc surface is arranged on the point of intersection of chisel edge and chip pocket, and terminal is connected with chip area, and the radian of described arc surface is between 70 ~ 75 degree.This drill bit, by the particular design to bit cutting part, significantly reduces the cutting force that drill bit produces in drilling process, improves drilling speed, decrease lathe loss, reduce energy loss.
Description
Technical field
The utility model belongs to high-precision numerical control machine drilling processing technique field, is specifically related to a kind of drill bit.
Background technology
1, existing bit cutting part mainly uses cross chisel edge or the design of large chisel edge, the feature of two kinds be all taken into account certain drilling ability while, rely on the intensity of its structure to come cutting resistance, finally complete the processing technology of drilling.
But the cutting force produced during the drill bit drilling of 2 these two kinds of traditional design is huge, this has not only increased the weight of the load born needed for the material of drill bit own, high-precision numerical control machine most valuable in whole system of processing is more made to bear unnecessary load, so its drilling speed that can use is limited, this not only limit working (machining) efficiency, time one also can affect the service precision of Digit Control Machine Tool for a long time, thus reduces its service life, the more important thing is and can bring unnecessary energy loss.
Utility model content
The purpose of this utility model is to provide a kind of drill bit, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of drill bit, comprise drill body, chisel edge, chip area, chip pocket and arc surface, described drill body and apex point center are provided with the chisel edge of 50 ~ 55 degree, described chisel edge both sides are provided with chip pocket, and described chip pocket terminal is 70 degree and is domaticly connected with chip area, and described arc surface is arranged on the point of intersection of chisel edge and chip pocket, and terminal is connected with chip area, the radian of described arc surface is between 70 ~ 75 degree.
Preferably, described drill body top is provided with cooling passage hole.
Preferably, described chip area is in the shape of a spiral around drill body.
Technique effect of the present utility model and advantage: this drill bit has carried out particular design to chisel edge and chip pocket part, when ensure that its structure has sufficient intensity, make the narrowed width of chisel edge, the space of chip pocket becomes large, thus reaches the object reducing cutting force, and this drill bit is by the particular design to bit cutting part, significantly reduce the cutting force that drill bit produces in drilling process, improve drilling speed, decrease lathe loss, reduce energy loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is chip pocket of the present utility model and chip area schematic diagram.
In figure: 1, chip pocket; 2, chisel edge; 3, arc surface; 4, chip area; 5, drill body; 6, cooling passage hole.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of drill bit as shown in Figure 1-2, comprise drill body 5, chisel edge 2, chip area 4, chip pocket 1 and arc surface 3, drill body 5 top is provided with cooling passage hole 6, drill body 5 and apex point center are provided with the chisel edge 2 of 50 ~ 55 degree, chisel edge 2 both sides are provided with chip pocket 1, chip pocket 1 terminal is 70 degree and is domaticly connected with chip area 4, arc surface 3 is arranged on the point of intersection of chisel edge 2 and chip pocket 1, and terminal is connected with chip area 4, chip area 4 is in the shape of a spiral around drill body 5, and the radian of arc surface 3 is between 70 ~ 75 degree.
When ensure that its structure has sufficient intensity, make the narrowed width of chisel edge 2, the space of chip pocket 1 becomes large, thus reach the object reducing cutting force, by the particular design to drill body 5 cutting tip, significantly reduce the cutting force that drill body 5 produces in drilling process, improve drilling speed, decrease lathe loss, reduce energy loss; Arrange cutting force when chip pocket 1 reduces drilling, drilling efficiency is improved, and production efficiency is high, the cost reduction that relative corrective maintenance is safeguarded, and reduces lathe power consumption, power and energy saving; The width of chisel edge 2, they ensure that the cutting ability in apex point centre, the design of arc surface 3 can guarantee the intensity guaranteeing its chisel edge 2 part under the prerequisite that chip pocket 1 space is enough large, the existence of chip area 4 constructs sufficient chip space, the domatic meeting of 70 degree that chip pocket 1 destination county is formed makes those metal fillings flow to herein fracture to be beneficial to it to be flowed out fast by chip area 4, thus ensure that the smoothness of whole working angles is with stable, avoids the generation of a large amount of unnecessary cutting force.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
