Description
Technical field
The utility model relates to a kind of semi-finished machining tool, a kind of extended type steel plate 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.And core drill is the form adopting multi-blade ring-type to cut, utilize 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 extended type steel plate special hollow drill bit better can process thicker steel plate, not fragile, cutting blade is through specially treated, not easy to wear, increases the service life.
Utility model content
The purpose of this utility model is a kind of extended type steel plate special hollow drill bit of raising the efficiency of utility model.
A kind of extended type steel plate 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 thread.
Further, the length of described drill body is 4.0cm ~ 7.0m, and diameter is 3.0cm ~ 4.0cm; Structure be hollow cylinder and front end for being provided with cutting blade.
Further, described drill body is provided with cutting blade, and cutting blade is that linear and arc line shaped distribute indirectly.
Further, described drill body is provided with chip area.
Further, the length of described staight shank drilling rod is 3.0cm ~ 6.0cm, and diameter is 2.0cm ~ 3.0cm; Structure is cylinder.
Further, described staight shank drilling rod is provided with binding thread, and screw thread curls up and is distributed on staight shank drilling rod.
The beneficial effects of the utility model are:
1, drill body described in the utility model, through quenching technical process, has certain toughness, not fragile, one-body molded, more sturdy and durable.
2, drill body described in the utility model is provided with cutting blade, through reasonably distributing, and processing work surface of can fitting; 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 thread, coordinates perfection with fixture, more fastening.
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 thread 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 ~ 6.0cm, and diameter is 2.0cm ~ 3.0cm, the oversize stability affecting drill bit, too shortly not easily installs.
As shown in Figure 1: staight shank drilling rod is provided with binding thread, screw thread and fixture perfect cooperation, more fastening.
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 structure is that linear and arc line shaped distribute indirectly, effectively can improve process velocity, increase work efficiency.
During processing work, make a sign with the place that marking pen will bore in advance.Staight shank drilling rod 1 spiral is arranged on the fixture of electric drill, alignment mark, cutting blade 3 first contacts processing work, slowly rotating, when there is mark, accelerating rotary speed, material bits are discharged from chip area 4, while processing, water spray can be utilized to reduce the temperature of drill bit, also material bits can be washed out.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.
