Abstract

The invention discloses a reaming auger bit for a continuous platform. The reaming auger bit comprises a head part, a handle part and a neck part located between the head part and the handle part. The head part, the neck part and the handle part are coaxial cylinders with the same central axis as the center. The head part and the neck part are provided with spiral chip discharging grooves, and a main cutting edge is formed by the head part and the chip discharging grooves at an end face common boundary. An inner edge is formed at the position, close to the center of the bit, of the main cutting edge, and the continuous platform is arranged on the main cutting edge. The continuous platform is parallel to the main cutting edge. Due to the fact that the continuous platform is arranged at the whole cutting edge, the cutting front angle of the main cutting edge is reduced equivalently. In the cutting process, the chip plastic deformation is increased, and chip breaking is easy. The reaming auger bit is particularly suitable for the situation of narrow chips under the reaming conditions, and meanwhile solid drilling of brittle materials can be taken into consideration. In addition, the design of the reaming auger bit is simpler compared with a traditional chip breaker groove, the reaming auger bit is particularly suitable for restructuring on a common bit, use requirements can be met, and cost can also be saved.

Description

A kind of platform reaming spiral bit continuously
Technical field
The present invention relates to the technical field of high-speed and high-efficiency cutting metal cutting tool, relate to a kind of platform reaming spiral bit continuously specifically, be especially applicable to the solid drilling occasion of little surplus reaming processing and fragile material.
Background technology
In solid carbide drill processing, except solid drilling, also often can run into the situation of reaming.If adopt general integrated carbide twist drill bit, when reaming, because chisel edge does not contact workpiece, centering is unstable.Now, cutting edge very easily collapses broken or breaking.During according to reaming bits such as high-speed steel, efficiency is very limited.Therefore design a kind of novel hard alloy reaming bit in highly-efficient processing, seem particularly necessary.
Summary of the invention
The present invention aims to provide a kind of applicable reaming occasion, can also take into account the continuous platform reaming spiral bit of the solid drilling of fragile material simultaneously.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of platform reaming spiral bit continuously, comprise head, shank and the neck between head and shank, described head, neck and shank are the coaxial clyinders centered by same central axis, described head and described neck are provided with spiral helicine chip area, described head and described chip area form a main cutting edge at end face common boundary place, described main cutting edge forms an inner edge near bit central place, described main cutting edge is provided with continuous platform, and described continuous platform is parallel with described main cutting edge.
Preferably, the width of described continuous platform is 3-5 drill bit feed of every rotation doubly.
Preferably, the angle of described continuous platform is set to 20 °-30 °.
Preferably, the outside of described head is provided with two spiral seamed edges, and the gap between two described seamed edges forms described chip area.
Preferably, the point of intersection of described seamed edge and described main cutting edge is formed with a point of a knife.
Preferably, the intersection place of described head two end faces is formed with a chisel edge.
Preferably, described shank is cylindrical structure, and outside handle of a knife is clamped in outside described shank to drive drill bit rotational.
Preferably, described inner edge is provided with anterior angle.
Adopt technique scheme, the present invention at least comprises following beneficial effect:
Continuous platform reaming spiral bit of the present invention, owing to having continuous platform at whole cutting edge place, is equivalent to the cutting anterior angle decreasing main cutting edge.In working angles, make chip plastic deformation increase, chip breaking is comparatively easy.Therefore the present embodiment is particularly suitable for the very narrow situation of chip under reaming condition, can also take into account the solid drilling of fragile material simultaneously.In addition, the present embodiment is more more succinct than the design of traditional chip-breaker, and be particularly suitable for changing a social system on all-purpose bit, can meet instructions for use again can be cost-saving.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figures 1 to 5, for one according to the invention continuous platform reaming spiral bit, comprise head 1, shank 3 and the neck between head 1 and shank 32, described head 1, neck 2 and shank 3 are the coaxial clyinders centered by same central axis, described head 1 and described neck 2 are provided with spiral helicine chip area 4, described head 1 and described chip area 4 form a main cutting edge 5 at end face common boundary place, described main cutting edge 5, for boring, is the main function structure of drill bit.Described main cutting edge 5 forms an inner edge 6 near bit central place, and described main cutting edge 5 is provided with continuous platform 10, and described continuous platform 10 is parallel with described main cutting edge 5.
Preferably, the width of described continuous platform 10 is 3-5 drill bit feed of every rotation doubly.Preferably, the angle of described continuous platform 10 is set to 20 °-30 °.The width of described continuous platform 10 and angle can adjust accordingly according to the cutting ability of machined material and cutting parameter and change, and the present embodiment is not construed as limiting this, and those skilled in the art should know.In accompanying drawing 5, T is the width of described continuous platform 10, and a is the angle of described continuous platform 10.
Preferably, the gap that the outside of described head 1 is provided with between two spiral seamed edges, 8, two described seamed edges 8 forms described chip area 4.
Preferably, described seamed edge 8 is formed with a point of a knife 9 with the point of intersection of described main cutting edge 5.
Preferably, the intersection place of described head 1 two end faces is formed with a chisel edge 7, and described chisel edge 7 is mainly used in head 1 intensity improving drill bit.
