Abstract
The utility model discloses a kind of depth drill for grinding low extruding sword, including auger spindle and drill main body, the drill main body is correspondingly arranged in the auger spindle side and is an integral structure setting, the drill main body surface is provided with cutting edge, the cutting edge twist structure setting on the mandrel of drill main body, there are two the cutting edge settings and is spaced apart setting, the cutting edge two sides, which respectively correspond, is provided with chip space, it is characterized by: the two sides of the cutting edge include cutting edge band and extruding land, the extruding land is less than the cutting edge band in radial width size in radial width size.The utility model solves cutter and fractures because of cutter caused by tripping problems, easy to operate, and the original support of cutter and squeezing effect had both been effectively ensured, and also effectively promotes service life and the stability of cutter.
Description
Technical field
The utility model relates to be machined to use cutting tool field more particularly to a kind of depth drill for grinding low extruding sword.
Background technique
For drill bit to the drawbore on solid material, depth drill is one kind that difficulty of processing is relatively high in drill bit.Due to it
Hole depth processing stability can almost, and depth drill, which is typically designed, can do Double-margin, it is therefore an objective to support, squeeze.Double-margin processes
Product aperture dimensionally stable, hole wall finish is more preferable.But Double-margin is designed to very high, the knife of the sword diameter bounce meeting of requirement of cutter
Tool has bounce that may squeeze sword height there is a phenomenon where squeezing sword to be higher than cutting edge band during once having bounce or processing and loading clamp
It can cause cutter when cutting edge band is in processing cutter occurs and fractures because of hard squeeze.
Utility model content
The purpose of this utility model is to provide a kind of solution cutter because cutter caused by tripping problems fractures, operation letter
It is single, the original support of cutter and squeezing effect had both been effectively ensured, has also effectively promoted the low extruding of mill in the service life and stability of cutter
The depth drill of sword.
The technical solution of the utility model is a kind of depth drill for grinding low extruding sword, including auger spindle and drill main body, described
Drill main body is correspondingly arranged in the auger spindle side and is an integral structure setting, and the drill main body surface is provided with cutting
Sword, twist structure setting is on the mandrel of drill main body for the cutting edge, and there are two the cutting edge settings and interval point
Cloth setting, the cutting edge two sides, which respectively correspond, is provided with chip space, and the two sides of the cutting edge include cutting edge band and extruding
Land, the extruding land are less than the cutting edge band in radial width size in radial width size.
It is described to squeeze land in radial width size than the cutting edge in one preferred embodiment of the utility model
Band is in radial width 0.02mm slight greatly.
In one preferred embodiment of the utility model, two cutting edges are arranged in rotational symmetry.
In one preferred embodiment of the utility model, the end side of the drill main body is provided with interior cold hole.
In one preferred embodiment of the utility model, the end side of the auger spindle is provided with the interior cold of helical structure
Slot.
Described in the utility model to grind the low depth drill for squeezing sword to be a kind of, the utility model solves cutter because of tripping problems
Caused cutter fractures, easy to operate, and the original support of cutter and squeezing effect has both been effectively ensured, and also effectively promotes the longevity of cutter
Life and stability.
Detailed description of the invention
Fig. 1 grinds the front view in low one preferred embodiment of depth drill for squeezing sword for the utility model；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
The preferred embodiment of the utility model is described in detail below, so that the advantages of the utility model and feature energy
It is easier to be readily appreciated by one skilled in the art, to be more clearly defined the protection scope of the utility model.
It is described in the utility model to grind the low depth drill for squeezing sword to be a kind of, as shown in Figure 1 with Figure 2, including auger spindle 1 and brill
Head main body 2, the drill main body 2 are correspondingly arranged in 1 side of auger spindle and are an integral structure setting, the drill main body 2
Surface is provided with cutting edge 3, and twist structure setting is on the mandrel of drill main body 2 for the cutting edge 3, the cutting edge 3
There are two settings and is spaced apart setting, and 3 two sides of cutting edge, which respectively correspond, is provided with chip space 4, and the two of the cutting edge 3
Side includes cutting edge band 5 and squeezes land 6, described to squeeze land 6 and be less than the cutting edge band 5 in diameter in radial width size
To width size, it is described that squeeze land 6 slighter greatly in radial width than the cutting edge band 5 in radial width size
0.02mm, two cutting edges 3 are arranged in rotational symmetry, and the end side of the drill main body 2 is provided with interior cold hole 7, described
The end side of auger spindle 1 is provided with the interior cold trap 8 of helical structure.
It by the way that cutting edge is processed into twolip band forms, and is slightly improved in form in traditional Double-margin, extruding
Land grinds low 0.02mm compared with cutting edge band, it is only necessary to operate on grinding machine all right.
Described in the utility model to grind the low depth drill for squeezing sword to be a kind of, the utility model solves cutter because of tripping problems
Caused cutter fractures, easy to operate, and the original support of cutter and squeezing effect has both been effectively ensured, and also effectively promotes the longevity of cutter
Life and stability.
The foregoing is merely specific embodiment of the present utility model, but the protection scope of the utility model is not limited to
This, anyone skilled in the art, can be without creative work in the technical scope disclosed by the utility model
The change or replacement expected, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model
It should be determined by the scope of protection defined in the claims.
