Description
Technical field
The utility model relates to a kind of chip breaking enhancement mode fluted drill.
Background technology
Chip breaking enhancement mode fluted drill is with the instrument of the circular hole of drilling workpiece by the rotary cutting of its relative fixed axis.Compared with the cutting tool of other types, the main cutting edge of standard chip breaking enhancement mode fluted drill is very long, is unfavorable for point bits and a chip breaking.In addition, when the use of chip breaking enhancement mode fluted drill, due to frictional heat, need to cool, temperature is suitably reduced, to reduce or remit the deformation probability of chip breaking enhancement mode fluted drill, extend the service life of chip breaking enhancement mode fluted drill.
Utility model content
The purpose of this utility model is to provide a kind of chip breaking enhancement mode fluted drill, and the length shortening major cutting edge improves point bits and the ability of chip breaking, solves the above-mentioned problems in the prior art.
Technical solution of the present utility model is:
A kind of chip breaking enhancement mode fluted drill, comprise the working portion, neck and the shank that set gradually, working portion comprises cutting portion and guide part, cutting portion is located at the end of guide part, cutting portion comprises major cutting edge, chisel edge, sword of splaying, auxiliary-blade, rear knife face, the both sides of chisel edge are respectively equipped with rear knife face, sword of splaying is located at the junction of major cutting edge and auxiliary-blade, the length of sword of splaying is 0.5mm, guide part is provided with helicla flute, and the length of working portion is 40mm, and the length of neck is 22mm, the length of shank is 20mm, and the sidepiece of shank is provided with mounting plane.
Further, this chip breaking enhancement mode fluted drill adopts wolfram steel or titanizing stainless steel to make.
Further, the centerline of working portion, neck and shank is equipped with cooling passage.
Further, described rear knife face is provided with away cuts groove, walks to cut groove and adopts linear or helical form, walks to cut groove and is communicated with helicla flute.
Further, the sidepiece of guide part is provided with the linear groove with guide part centerline parallel, and linear groove is communicated with helicla flute successively.
The beneficial effects of the utility model are: this kind of chip breaking enhancement mode fluted drill, by arranging in the junction of major cutting edge and auxiliary-blade sword of splaying, come, in the to a certain degree lower length shortening major cutting edge, to improve point bits and chip breaking ability.Rear knife face is provided with away cuts groove, walks to cut groove and adopts linear or helical form, walks to cut groove and is communicated with helicla flute, improves point bits and chip breaking ability further.

Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment one
A kind of chip breaking enhancement mode fluted drill, comprise the working portion set gradually, neck 1 and shank 2, as Fig. 1, working portion comprises cutting portion and guide part, cutting portion is located at the end of guide part, cutting portion comprises major cutting edge 3, chisel edge 7, to splay sword 4, auxiliary-blade 5, rear knife face 6, as Fig. 3, the both sides of chisel edge 7 are respectively equipped with rear knife face 6, sword 4 of splaying is located at the junction of major cutting edge 3 and auxiliary-blade 5, as Fig. 2, the length of sword 4 of splaying is 0.5mm, guide part is provided with helicla flute 8, the length of working portion is 40mm, the length of neck 1 is 22mm, the length of shank 2 is 20mm, the sidepiece of shank 2 is provided with mounting plane 9.
This kind of chip breaking enhancement mode fluted drill, by arranging at major cutting edge 3 and the junction of auxiliary-blade 5 sword 4 of splaying, in the to a certain degree lower length shortening major cutting edge 3, improves point bits and chip breaking ability.The centerline of working portion, neck 1 and shank 2 is equipped with cooling passage.By the cooling passage of inside, carry out cooling processing.
Embodiment two
Embodiment two is substantially identical with the structure of embodiment one, embodiment two and embodiment one unlike, rear knife face 6 is provided with away cuts groove 10, as Fig. 5, walks to cut groove 10 and adopts helical form, walk to cut groove 10 and be communicated with helicla flute 8, improves point bits and a chip breaking ability further.The sidepiece of guide part is provided with the linear groove 11 with guide part centerline parallel, and as Fig. 4, linear groove 11 is communicated with helicla flute 8 successively, by the setting of linear groove 11, improves chip removal ability further.
This chip breaking enhancement mode fluted drill adopts wolfram steel or titanizing stainless steel to make.Titanizing chip breaking enhancement mode fluted drill can bore stainless steel brick, concrete etc.This kind of chip breaking enhancement mode fluted drill, hard sharp process easily, conveniently.By the length of reasonable disposition working portion, neck 1 and shank 2, under the prerequisite guaranteeing chip breaking enhancement mode fluted drill intensity, there is larger drilling depth.
