Abstract
The invention discloses a chip suction type drill bit which comprises a guide body, a support pipe and a drill edge, wherein an edge groove is formed in the head part of the guide body; a connecting support rod is arranged at the tail part of the guide body; the drill edge is arranged on the edge groove; the support pipe is arranged on the connecting support rod. The chip suction type drill bit has the benefits that the drilling efficiency is remarkably improved, the graphite dust is guided out through a diversion trench during the chip removal without polluting the environment, the abrasion of the drill bit is reduced and no hole position deviation is caused during the drilling.
Description
Technical field
The present invention relates to a kind of suction bits formula drill bit.
Background technology
Current graphite Drilling operation instrument is confined to lengthen fluted drill, because working depth is comparatively dark, in order to chip removal must be get to certain depth will move back brill chip removal, has several shortcoming like this, as:
1, drilling time is long, and efficiency is low;
2, during chip removal, graphite dust easily wafts in atmosphere, can damage, damage human body respiration environment;
3, fluted drill repeatedly comes and goes and easily causes bit wear;
4, the aperture error that chip removal can cause front and back is come and gone;
5, due to not guiding, easily produce when holing that hole is biased to be moved.
Summary of the invention
The object of the invention is to solve the problems referred to above in prior art existing for drill bit, provide a kind of bits formula drill bit of inhaling to solve the problems referred to above.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of suction bits formula drill bit, comprise guide way, stay pipe and drill lip, described guide way head is provided with cutting edge groove, and guide way afterbody is provided with and connects pole, and described drill lip is arranged on cutting edge groove, and described stay pipe is arranged on and connects on pole.
Preferably, the angle between the cutting edge of described drill lip is 30 ~ 60 °, and the root of drill lip is provided with chip removal mouth.
Preferably, the surface of described guide way is provided with 4 ~ 6 guiding gutters.
Preferably, described stay pipe is seamless hollow pipe.
Preferably, described stay pipe afterbody is provided with chip-removal hole.
Beneficial effect of the present invention is mainly reflected in: drilling efficiency significantly improves; During chip removal, graphite travel fatigue is derived by guiding gutter, does not pollute the environment; The wearing and tearing of drill bit reduce; Can not produce during boring that hole is biased to be moved.
Accompanying drawing explanation
Fig. 1 is side view of the present invention;
Fig. 2 is top view of the present invention.
Detailed description of the invention
See accompanying drawing 1 and Fig. 2, a kind of suction bits formula drill bit, comprise guide way 1, stay pipe 2 and drill lip 5, the surface of described guide way 1 is provided with 4 guiding gutters 11, forms 2 guide supports 13 and two guide supports 17, and two guide supports 13 of symmetry are provided with cutting edge groove 12, described drill lip 5 is arranged on cutting edge groove 12, form pod apertures 14 between drill lip 5 and guide way 1, guide way 1 afterbody is provided with and connects pole 9, and described stay pipe 2 is arranged on and connects on pole 9.
Preferably, the angle between the cutting edge 3 of described drill lip 5 and cutting edge 4 is 30 ~ 60 °, and the root of drill lip 5 is provided with chip removal mouth 6.
Preferably, described stay pipe 2 is seamless hollow pipe, and stay pipe afterbody is provided with chip-removal hole 15.
Operation principle:
1, after drill bit enters processome, because guide way plays orientation, so in process, drill bit running orbit is restricted, and greatly reduces position, hole shift phenomenon.
2, in process, drill lip carries out drilling with normal speed, and guide way plays drilling guide function, and flow guide function, flow guide outside support bar, inner side chip-removal hole chip removal.
3, add in drilling and connect with dust catcher in stay pipe one end man-hour, after drill bit enters processome, because dust catcher produces negative pressure to whole drill bit inwall, air-flow flows towards drill bit direction outside processome and stay pipe, through guide way, flow to towards drill bit end, the chip that drilling produces together with air-flow by together because negative pressure is siphoned away by pod apertures and chip-removal hole by dust catcher.
4, the chip owing to getting out was siphoned away at that time, and drill bit can drilling forward always, substantially increases process velocity like this.And greatly reduce bit wear.
In sum, be only preferred embodiment of the present invention, not be used for limiting scope of the invention process, all equalizations of doing according to shape, structure, feature and the spirit described in the claims in the present invention scope change and modify, and all should be included in right of the present invention.
Claims (5)
