Description
Technical field
The utility model relates to a kind of semi-finished machining tool, a kind of Quick-type frame structure building partition wall special hollow drill bit of raising the efficiency.
Background technology
Drill bit goes out through hole or blind hole in order to drilling on processing work, and can to the cutter of existing hole reaming.Drill bit is used in a lot of field, comprise machinery, drilling well, medical, timber, stone, glass etc., and core drill is the form adopting multi-blade ring-type to cut, utilizes the external diameter annulus of a drill bit cutting hole, do not cut mid portion, thus substantially increase drilling efficiency, and in conjunction with magnetic support rig etc., on-the-spot bore operation at any time can be realized, relative to common fluted drill, efficiency is more increased, and cuts brisk.And frame structure building partition wall special hollow drill bit can support to process the hole more strengthened, more convenient, safer, the utility model is designed to indent triangle cutting blade, better can improve process velocity.
Utility model content
The purpose of this utility model is a kind of Quick-type frame structure building partition wall special hollow drill bit of raising the efficiency of utility model.
A kind of Quick-type frame structure building partition wall special hollow drill bit of raising the efficiency, main body is made up of drill body and staight shank drilling rod, its innovative point is: described drill body is hollow cylinder, described drill body is provided with cutting blade, described staight shank drilling rod is cylinder, and described staight shank drilling rod is provided with binding groove.
Further, the length of described drill body is 5.0cm ~ 8.0m, and diameter is 4.0cm ~ 5.0cm; Structure is hollow cylinder and front end is indent triangle.
Further, described drill body is provided with cutting blade, and cutting blade and horizontal line angle are 20 ~ 35 degree.
Further, described drill body is provided with chip area.
Further, the length of described staight shank drilling rod is 3.0cm ~ 5.0cm, and diameter is 4.0cm ~ 5.0cm; Structure is cylinder.
Further, described staight shank drilling rod is provided with binding groove, binding groove 0.5cm ~ 1.0cm, and long 1.5 ~ 2.0cm, structure is rectangular configuration.
The beneficial effects of the utility model are:
1, drill body described in the utility model, through quenching technical process, sturdy and durable, there is certain toughness, not fragile, one-body molded, more attractive in appearance.
2, drill body described in the utility model is provided with cutting blade, and through the design of structure and angle, cutting blade material is carbide alloy, sturdy and durable, not easy to wear.
3, drill body described in the utility model is provided with chip area, can effectively be discharged by material bits.
4, staight shank drilling rod described in the utility model is provided with binding groove and fixture when fixing, rotation more, folder more firm.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Fig. 1 is structural scheme of mechanism of the present utility model.
Fig. 2 is the cutting end view of the utility model drill bit.
Detailed description of the invention
Hollow boring bit as shown in Figure 1, is made up of staight shank drilling rod 1, drill body 2, cutting blade 3, chip area 4 and binding groove 5.
The structure of straight shank drill is as shown in Figure 1: staight shank drilling rod 1 is cylinder, and the length of described staight shank drilling rod is 3.0cm ~ 5.0cm, and diameter is 4.0cm ~ 5.0cm, the oversize stability affecting drill bit, too shortly not easily installs.
As shown in Figure 1: staight shank drilling rod is provided with binding groove, can be more along with what rotate, folder more firm, can prevent from rupturing.
One end of straight shank drill is drill body 2 as shown in Figure 1, and be hollow cylinder, drill body 2 is provided with cutting blade 3, and cutting blade 3 is indent triangle, effectively can improve process velocity, increase work efficiency.
During processing work, make a sign with the place that marking pen will bore in advance.Be arranged on the fixture of electric drill by staight shank drilling rod 1, alignment mark, cutting blade 3 first contacts processing work, slowly rotates, when there is mark, accelerate rotary speed, material bits are discharged from chip area 4, as large in the power that is hampered during drilling deep hole, can repeatedly withdrawing, to assist cutter chip removal.When again holing after withdrawing, the situation of boring not go down as occurred, needs iron filings in first cleaning eye, then continues boring, through after a period of time, machines.
The above is preferred embodiment of the present utility model, can not limit the interest field of the utility model with this.It should be pointed out that for those skilled in the art, the technical solution of the utility model is modified or equivalent replacement, do not depart from protection domain of the present utility model.
