It is not easy to exclude scrap, vibrates larger, unstable problem.
The technical solution of the utility model is achieved in that
A kind of helical angle straight trough molding cutter, including knife handle, first segment blade, second segment blade, third section blade, spiral
Angle, cutter head, blade, straight trough side and right angle, one end side of the knife handle are provided with the first segment blade, the first segment knife
One end of body and the separate knife handle is provided with the second segment blade, the second segment blade and the separate first segment blade
One end be provided with the third section blade, between the first segment blade, the second segment blade and the third section blade
Form the helical angle, the third section blade and one end far from the second segment blade is provided with the cutter head, the knife
The two sides of head are provided with the blade, and the side of the blade is provided with the straight trough side, one end setting on the straight trough side
There is the right angle.
Preferably, the handle diameter of the knife handle is all larger than the first segment blade, the second segment blade and the third section
The diameter of blade.
Preferably, the side on the straight trough side and the angle of the blade are 115 degree.
Preferably, a height of 15 millimeters of the sword of the blade.
Preferably, the angle of the helical angle is 30 degree.
The utility model provides a kind of helical angle straight trough molding cutter, has the beneficial effect that:
(1), the utility model uses the mode of helical angle, and the sword for making cutter increase participation cutting is long, compares cutting
Continuous to reduce vibration, cutting width, which changes from small to big to become smaller again, makes stable cutting, and helical angle increases real work anterior angle, makes
Cutting edge is sharp, reduces cutting force and convenient for chip removal, therefore the quality of machining will be quite a lot of, and straight trough side is set in this case
Meter, improves the working efficiency of cutter, processing shell when stiffness and circularity effect it is more preferable.
(2), 30 degree of helical angle feature is sharper, cutting face finishing, is cut more accurate.
