Abstract
The utility model discloses a motor rotor flat copper edging knife, comprising an integrated circular body and a blade extending along the overall circumference of the circular body, characterized in that knife angle of the blade ranges from 50degree to 70degree, with its optimum degree to be 60degree. Multi-time feeds of the motor rotor flat copper edging knife will not cause cold hardening of the flat copper and edging force is needless to be too strong so as to prevent damaging the lathe accuracy.
Description
Technical field
The utility model relates to a kind of cutter, relates in particular to a kind of rotor copper bar edging cutter with copper bar tensioner in rotor edging groove.
Background technology
Existing edging cutter point of a knife adopts the knife-edge angle of tack or 120 °.The edging cutter is installed on the knife rest of lathe, and rotor is installed on lathe dog and the tailstock.Moving carriage edging one by one is positioned at the copper bar of copper bar groove, makes the degree of depth that occurs indentation on the copper bar and utilize length feed control indentation make copper bar no longer loosening in the copper bar groove with the tensioner copper bar.But above-mentioned edging cutter repeatedly feed meeting causes the flow harden of copper bar, adds knife-edge angle unreasonable of former employing, edging pressure is increased and damages the precision of lathe.
The utility model content
Goal of the invention of the present utility model aims to provide a kind of rotor copper bar edging cutter of avoiding influencing copper bar quality and lathe precision, to overcome the deficiency that prior art exists.
In order to realize the foregoing invention purpose, a kind of rotor copper bar edging cutter of the present utility model is made of the circular body of one and the point of a knife that extends along the circular body whole circumference, and it is characterized in that: the knife-edge angle of described point of a knife is 50 °～70 °.Knife-edge angle the best of described point of a knife is 60 °.
Adopt technique scheme, rotor copper bar edging cutter of the present utility model repeatedly feed can not cause the flow harden of copper bar, thereby edging pressure does not need the excessive precision of avoiding damaging lathe.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, circular body 2, point of a knife 21, knife-edge angle
Embodiment
Rotor copper bar edging cutter as shown in Figure 1 selects for use cold work die steel CrWMn to make, and is made of the circular body 1 of one and the point of a knife 2 that extends along circular body 1 whole circumference, and the knife-edge angle 21 of its point of a knife 2 is 50 °～70 °, and the best is 60 °.
On lathe copper bar is carried out edging from the utility model practical application, effect is fine: repeatedly feed can not cause the flow harden of copper bar, thereby edging pressure does not need the excessive precision of avoiding causing damaging lathe.
