Abstract
The utility model discloses a novel chip breaker groove in a boron nitride blade and particularly relates to the novel chip breaker groove which is formed in the boron nitride blade and used for efficiently machining quenched steel. The novel chip breaker groove solves the technical problems that when the quenched steel is turned through the boron nitride blade, the phenomena that the blade is struck, the surface of a workpiece is scratched, and a person is injured by cuttings easily occur. The novel chip breaker groove is formed in a chamfered edge of the tool tip of the blade. The chip breaker groove comprises a ramp I, a ramp II and a perpendicular face perpendicular to the upper surface of the blade. The chip breaker groove is defined by the ramp I, the ramp II and the perpendicular face. By the adoption of the structure, longer cuttings are prevented from being generated, and the phenomena that the blade is struck, the surface of the workpiece is scratched and the person is injured by the cuttings are avoided.
Description
Technical field
The utility model relates to a kind of chip-breaker, is specifically related to a kind of novel chip-breaker that is opened in high efficiency processing hardened steel on boron nitride blade.
Background technology
At present in the time of boron nitride blade turning processing hardened steel, due to the characteristic of machined material itself, when boron nitride blade turning, can produce longer flow chip, because produce longer smear metal, it is often wound on cutter or surface of the work, easily like this there is forging a knife, pulling surface of the work, also easily occur the phenomenon that smear metal is hurted sb.'s feelings.
Summary of the invention
The technical problems to be solved in the utility model easily occurs forging a knife, pulling also easily occurring the phenomenon that smear metal is hurted sb.'s feelings by surface of the work while being boron nitride blade turning processing hardened steel, provides a kind of simple in structure, the novel chip-breaker on boron nitride blade easy to use.
For achieving the above object, the utility model adopts following technical proposals: the novel chip-breaker on a kind of boron nitride blade, chip-breaker is located on the chamfered edge of blade point of a knife, described chip-breaker comprises domatic I, domatic II and the vertical plane vertical with the upper surface of blade, and domatic I and domatic II and vertical plane surround chip-breaker.
Described vertical plane is arcwall face.
Described domatic I and the angle of domatic II are 100-160 °
Described domatic I and the angle of domatic II and vertical plane are 45-70 °.
The angle of described chamfered edge and the upper surface of blade is 20-30 °.
The utility model is simple in structure, easy to use, and the longer flow chip producing when boron nitride blade turning can be cut off in time, prevents to prevent the smear metal grown and forge a knife, pull surface of the work, the phenomenon that smear metal is hurted sb.'s feelings.With the disposable boron nitride blade of chip-breaker, the chip-breaker that the boron nitride part of blade point of a knife forms, can keep the effect of smear metal processing for a long time; Adopt special boron nitride material, can carry out high efficiency Turning of Hardened Steels processing; Special chip-breaker shape design, can guarantee that blade adds man-hour, the smear metal processing from quenching position to the position of not quenching; Can shorter time carry out disjunction smear metal; Extend the service life of cutter.

Fig. 3 is the side-looking structural representation of blade.
Fig. 4 is chip-breaker broken section structural representation.
The specific embodiment
As shown in Figures 1 to 4, the utility model chip-breaker 1 is located on the chamfered edge 3 of blade 2 points of a knife, and described chip-breaker 1 comprises domatic I4, domatic II5 and the vertical plane 6 vertical with the upper surface 8 of blade 2, and domatic I4 and domatic II5 and vertical plane 6 surround chip-breaker 1.
Described vertical plane 6 is arcwall face.
Described domatic I4 and the angle C of domatic II5 are 100-160 °
Described domatic I4 and the angle E of domatic II5 and vertical plane are 45-70 °.Described vertical plane is the virtual plane vertical with the upper surface 8 of blade.
Described chamfered edge 3 is 20-30 ° with the included angle B of the upper surface 8 of blade 2.
The point of a knife that the blade 2 of chip-breaker 1 is set is that radius R is the circular arc of 0.4-3.0mm, and the width F of chamfered edge 3 is 0.5-0.7mm, and on chamfered edge 3, the width D in chip-breaker 1 outside is 0.1-0.2 mm.
The flow chip producing when boron nitride blade turning processing hardened steel cleans out after chip-breaker cuts off, and prevents and forges a knife, pulls surface of the work, the phenomenon that smear metal is hurted sb.'s feelings.
