Abstract

The utility model discloses an inlay alloy bit, including stalk portion and cutter body, the one end of stalk portion is connected with the one end of cutter body, is equipped with the chip groove of spiral on the cutter body, and the other end of cutter body is equipped with inlays the groove, and it has the drill tip to inlay in inlaying the groove, and the nose angle of this drill tip is 110 -130, and the relief angle of drill tip is 8 -12, is equipped with the cutting part on the drill tip, and all sword anterior angles of cutting part are 5 -7, and the ligament width of cutting part is the 6 -8% of this cutting part diameter. The utility model discloses an inlay alloy bit can carry out the split.

Description

Edge alloy bit
Technical field
This utility model Machining Technology field, is specifically related to a kind of edge alloy bit.
Background technology
When workpiece is processed, the contact of drill bit and workpiece is exactly contacting between the cutting edge of drill bit and workpiece, the parts needing processing are quickly cut by cutting edge, fast due to cutting speed and cutting workpiece is more and more harder, cause that cutting edge constantly produces higher abrasion and higher temperature in cutting, and application that hard alloy is in drill bit is more and more extensive, due in working angles, the abrasion of the metal fillings constantly formed on the rake of drill bit and cause crescent hollow abrasion, rear knife face sliding along drill bit is also caused flank wear by the workpiece processed, blade is up to significantly high temperature in front sensibilities simultaneously, to cause that divergent contour weares and teares, then on knife face, temperature significantly lowers, present abrasive wear, as can be seen here, the reliability of carbide drill and life-span need higher raising and requirement.
Summary of the invention
For the problems referred to above, this utility model provides a kind of edge alloy bit that can carry out splitting.
The technical scheme solving above-mentioned technical problem is as follows:
Edge alloy bit, including shank and cutter hub, one end of shank is connected with one end of cutter hub, and cutter hub is provided with the chip area of spiral, and the other end of cutter hub is provided with embedding groove, embedding groove is inlaid with apex point, the nose angle of this apex point is 110 130 ��, and the relief angle of apex point is 8 12 ��, and apex point is provided with blade, the rake angle of blade is 57 ��, and the ligament width of blade is the 6 8% of this diameter at edge part.
Chisel edge width is diameter at edge part the 2 4% of described apex point,
Core thickness is this cutter hub diameter the 30 35% of described cutter hub.
Have employed such scheme, the drill bit in this utility model and cutter hub are removably disposed mode, not only reduce the cost of manufacture of cutter, have saved resource, and after bit wear, it is possible to it is individually replaced drill bit, without changing whole cutter.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of structural representation of the present utility model.
Fig. 2 is the A direction view of Fig. 1;
Fig. 3 is the profile of B B line along Fig. 1;
In accompanying drawing, 1 is shank, and 2 is cutter hub, and 3 is chip area, and 4 is apex point.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
As shown in Figure 1 to Figure 3, edge alloy bit of the present utility model, including shank 1 and cutter hub 2, one end of shank 1 is connected with one end of cutter hub 2, cutter hub 2 is provided with the chip area 3 of spiral, core thickness L1 is this cutter hub diameter the 30 35% of described cutter hub, it is preferable that core thickness L1 is this cutter hub diameter the 30% of cutter hub.The other end of cutter hub 2 is provided with embedding groove, is inlaid with apex point 4 in embedding groove, and the nose angle �� of this apex point 4 is 110 130 ��, it is preferable that the nose angle of apex point 4 is 120 ��. The relief angle �� of apex point is 8 12 ��, it is preferable that the relief angle �� of apex point 4 is 10 ��. Apex point is provided with blade, and the rake angle �� of blade is 57 ��, it is preferable that the rake angle �� of blade is 6 ��. Ligament width L2 is this diameter at edge part the 6 8% of blade, it is preferable that ligament width L2 is this diameter at edge part the 7% of blade, chisel edge width L3 is diameter at edge part the 2 4% of apex point, it is preferable that the chisel edge width L3 of apex point is the 3% of diameter at edge part.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
