Abstract
The invention relates to a machining tool, in particular to a rapid type hollow drill bit special for steel plates and capable of improving efficiency. A main body of the drill bit is composed of a drill bit body and a straight-handle drill rod. The drill bit is characterized in that the drill bit body is a cylinder, a cutting edge is arranged on the drill bit body and provided with diamond sand grains, and machining speed can be increased; the straight-handle drill rod is a cylinder and provided with a frosted layer, friction force between the drill rod and a clamp can be increased, and a locating groove is further formed in the straight-handle drill rod and can improve stability of the drill bit.
Description
Technical field
The present invention relates to a kind of rough machined machining tool, a kind of Quick-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.Drill bit is used in a lot of field, comprises machinery, drilling well, medical, timber, stone, glass etc., and core drill (having another name called core drill, Steel Plate Guide Drill, cave brill), its title is Multi-blade Steel Plate Drill.It 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.The present invention adds diamond gravel on cutting blade, can accelerate cutting speed.
Summary of the invention
The object of the invention is to invent a kind of Quick-type steel plate special hollow drill bit of raising the efficiency.
A kind of Quick-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 cutting edge is provided with diamond gravel, described staight shank drilling rod is cylinder, and described staight shank drilling rod is provided with frosted layer, and described staight shank drilling rod is also provided with locating slot.
Further, the length of described drill body is 2.0cm ~ 3.0cm, and diameter is 2.0cm ~ 2.5cm; Structure is hollow cylinder.
Further, described drill body is provided with cutting blade, and cutting blade and horizontal line angle are 20 ~ 40 degree.
Further, described cutting edge is provided with diamond gravel, and diamond gravel is microgranular.
Further, described drill body is provided with chip area.
Further, the length of described staight shank drilling rod is 2.5cm ~ 3.5cm, and diameter is 1.5cm ~ 2.5cm.
Further, on described staight shank drilling rod, frosted layer is evenly distributed in drilling rod surface.
Further, described staight shank drilling rod is provided with locating slot, and long is 1.5cm, and wide is 1.0cm.
Beneficial effect of the present invention is:
1, drill body of the present invention, through quenching technical process, sturdy and durable, there is certain toughness, not fragile.
2, drill body of the present invention is provided with cutting blade, through the design of structure and angle, cutting blade material is carbide alloy, sturdy and durable, not easy to wear, can drilling rate be improved.
3, drill body of the present invention is provided with chip area, can effectively be discharged by material bits.
4, cutting blade of the present invention is provided with diamond gravel, can effective auxiliary cutting edge, accelerates cutting speed.
5, staight shank drilling rod of the present invention is provided with frosted layer, can increase frictional force, reinforces the connection of staight shank drilling rod and fixture.
6, staight shank drilling rod of the present invention is provided with rectangle locating slot, effectively can be located by drill bit, prevent from rocking in process, cause Drill Crack.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 is structural scheme of mechanism of the present invention.
Fig. 2 is the cutting end view of drill bit of the present invention.
Detailed description of the invention
Bottom expanding drill as shown in Figure 1, is made up of staight shank drilling rod 1, drill body 2, cutting blade 3, diamond gravel 4, chip area 5, frosted layer 6 and locating slot 7.
The structure of straight shank drill is as shown in Figure 1: staight shank drilling rod 1 is cylinder, and the length of drill body is 2.5cm ~ 3.5cm, and diameter is 1.5cm ~ 2.5cm, and structure is hollow cylinder, the oversize stability affecting drill bit, too shortly not easily installs.
As shown in Figure 1: staight shank drilling rod is provided with frosted layer, can frictional force be increased, reinforce the connection of staight shank drilling rod and fixture; Also be provided with locating slot, can prevent from rocking in process, cause Drill Crack.
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 provided with diamond gravel 4, can accelerate reaming speed, increase work efficiency.
During boring, be arranged on the fixture of electric drill by staight shank drilling rod 1, cutting blade 3 first contacts processing work, slowly rotates, when there is mark, accelerate rotary speed, diamond gravel 4 starts assisted machining, improves cutting speed, material bits are discharged from chip area 5, through after a period of time, machine.
The above is the preferred embodiment of the present invention, can not limit the interest field of the present invention with this.It should be pointed out that for those skilled in the art, technical scheme of the present invention is modified or equivalent replacement, do not depart from protection scope of the present invention.
