Abstract
The utility model relates to a machining tool, an efficiency of work is improved quick reaming specific drill bit. The body is bored for the straight shank to the main part, and the straight shank bores personally experiences sth. Part of the body to the cylinder the straight shank bores to personally experience sth. Part of the body to go up to open there is the chip groove, cutting blade has two, forms the chip groove between the rotatory orbit of cutting cutting part, cutting blade is last to be equipped with two alloy cutting edges. Characterized by: be equipped with the alloy cutting edge on the drill bit cutting blade and can carry out quick reaming, improve work efficiency to can prevent cutting blade's wearing and tearing, increase of service life.
Description
Technical field
The utility model relate to a kind of semifinishing or eventually processing repair hole instrument, specifically a kind of quick reaming target drill of increasing work efficiency.
Background technology
Drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Drill bit and reamer are the same things, it is but the effect difference played, be all utilize cutting blade to carry out drilling, a gang of semifinishing for hole of reamer or eventually processing, for the expansion of the preprocessing before cutting with scissors or grinding or blank hole, there are 2 to 4 blade bands, without horizontal blade, anterior angle and relief angle little along the change of cutting blade, add man-hour guide effect good, axial drag is little, and machining condition is better than boring.
Utility model content
The purpose of this utility model is a kind of quick reaming target drill of increasing work efficiency.
A kind of quick reaming target drill of increasing work efficiency, main body is staight shank drill body and cutting blade, its innovative point is: described staight shank drill body is cylinder, described staight shank drill body has chip area, described cutting blade has two, form chip area between cutting edge portion rotational trajectory, described cutting blade is provided with two alloy blades.
Further, the length of described staight shank drill body is 20 ~ 35cm.
Further, described cutting blade and horizontal line angle are 20 ~ 35 degree, and cutting blade is back taper.
Further, described cutting blade is provided with two alloy blades.
Further, two alloy blade structures on described cutting blade are triangle.
Further, described drill body is cylinder, and its length is 15 ~ 20cm.
Further, described drill body is dispersed with one deck frosted layer.
The beneficial effects of the utility model are:
1, straight shank drill described in the utility model is one-body molded, through quenching technical process, sturdy and durable, has certain toughness, not fragile.
2, the utility model drill bit is provided with two blades, and the design of the angle that blade is carried out and structure, make blade can be good at laminating processing work surface, ensure crudy.
3, be provided with two alloy blades in blade described in the utility model, reaming speed can be accelerated, increase work efficiency.
4, drill body outer surface described in the utility model is provided with the frictional layer increasing frictional force, and can increase the frictional force of drill bit and rotating shaft, what drill bit was accommodated is 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
Straight shank drill as shown in Figure 1, by drill body 1, drill body 2, chip area 3, cutting blade 4, alloy blade 5, frosted layer 6 is formed.
The structure of straight shank drill is as shown in Figure 1: drill body 1 is cylinder, the total length of drill body is 10 ~ 20cm, handling and the use of straight shank drill are mainly considered in the design of this structure, too shortly not easily to install, oversize poor stability, and adopt described drill body extexine to be provided with the frictional layer 6 of frictional force, can increase the frictional force of drill bit and rotating shaft, what drill bit was accommodated is more firm.
One end of straight shank drill is drill body 2 as shown in Figure 1, and drill body 2 upper end is provided with cutting blade 4, and described cutting blade 4 has two, is in a center of symmetry about the rotary middle spindle of drill body.
Described drill body 2 has chip area 3, during processing work, cuts the bits material produced and automatically discharge from chip area 3.
Described cutting blade 4 is provided with two alloy blades 5, can accelerate reaming speed, increase work efficiency.
During processing work, the drill jig of electric drill firmly clamps drill body 1, first bit point of the drill contacts processing work surface, and carry out preparatory processing, then cutting blade 4 starts to contact processing work, and produces a large amount of material bits, and material bits are automatically discharged from chip area 3, then alloy blade 5 is processed rapidly, can prevent the excessive wear of cutting blade 4.
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.
