Angle between the first break bar conical surface 1 and the second break bar conical surface 2 is θ, 160 ° of < of 100 ° of < θ, when 100 ° of θ <
When, blade is excessively sharp, and the pressure that blade is born when in use is big, is easy to appear and scratches knife rest etc.；When θ > 160 °, break bar cone
Face and blade almost on a horizontal plane, are unfavorable for blade and play dissection, influence the use of break bar.
Optionally, first locating slot 8 is column structure, the cross sectional shape of first locating slot 8 be it is arc-shaped, three
Angular, quadrangle or polygon, the quantity of first locating slot 8 are 1-4.
Break bar provided by the embodiments of the present application, the cross sectional shape of the first locating slot 8 be arc-shaped, triangle, quadrangle or
Polygon, if Fig. 3-6 is that the first locating slot cross sectional shape provided by the embodiments of the present application is followed successively by arc-shaped, triangle, four sides
The cutting wheel structure schematic diagram of shape and polygon, cross-sectional shapes are that the first locating slot 8 of triangle is the most stable, such as Fig. 4 institute
The cross sectional shape for showing the first locating slot 8 in this cutting wheel structure is triangle and quantity is 3, due to the size of locating bar in break bar
Limited, the quantity of the first locating slot 8 is limited to 1-4, and when the quantity of the first locating slot 8 is excessive, size necessarily becomes smaller,
Processing dimension and processing request can be all restricted in process.
Optionally, the width of first locating slot 8 is 0.2-0.5mm, and the height of first locating slot 8 is 0.2-
The difference of 0.5mm, the width and height of first locating slot 8 and the width of the anchor point 7 and height is 0.01-
0.03mm。
Break bar provided by the embodiments of the present application, anchor point 7 is complementary with 8 shape of the first locating slot, and quantity is consistent, the first positioning
The difference of the width and height of slot 8 and the width of anchor point 7 and height is 0.01-0.03mm, when the difference of the two diameter is less than
When 0.01mm, assembly difficulty is improved, when the difference of the two diameter is greater than 0.03mm, easily occurs cooperating not close, reduction cutting
Effect etc., similarly, the difference of the depth of the two also control within the scope of 0-0.03mm, i.e., anchor point 7 is completely through the first locating slot 8
Run through the first locating slot 8 with 7 part of anchor point, is in order to guarantee that slewing area is limited during break bar rotates, no in this way
It can deflect, for cross sectional shape provided by the embodiments of the present application be as Figure 7-8 triangle and the first positioning that quantity is 3
Slot 8 respectively anchor point 7 completely or partially run through break bar when structural schematic diagram.
Optionally, the break bar with a thickness of 0.65-1.0mm, the diameter of the break bar is 2.0-4.0mm, described first
