Detailed Description
In order to better understand the purpose, structure and function of the present invention, the present invention will be described in detail with reference to the accompanying drawings 1-8.
A die forging wing rail bottom slope milling cutter comprises a cutter head 1 and three groups of blades arranged on the cutter head 1; a plurality of chip breaking grooves 11 for chip removal are formed in the cutter head 1, the outer surface of the cutter head 1 and the forming surface of the bottom slope of the wing rail needing to be processed are arranged in a profiling mode, each group of blades are uniformly distributed on the cutter head 1 in an annular mode, three groups of blades are sequentially arranged in a layered mode along the axial direction of the cutter head 1, the three groups of blades are arranged in a staggered mode, the three groups of blades are sequentially connected end to end on the same axial section, and the three groups of blades are a group of blades I2, a group of blades II 3 and a group of blades III 4 respectively; each blade 2 is provided with an outer convex arc cutting edge and is arranged in a copying mode with the upper end of the bottom slope of the wing rail, the middle of each blade III 4 is in an inner concave arc shape, and two ends of each inner concave arc shape are outwards transited to a plane from a tangent line 7. And the lower end of the bottom slope of the wing rail is arranged in a copying way.
And the cutter head 1 is provided with a radial positioning groove 5 and a plurality of positioning holes 6. The positioning is more accurate, convenient and convenient to install.
The angle α between said tangent 7 to the plane of each blade three 4 is between 15 ° and 20 °. Preferably 18 degrees, and an 18-degree tangent chamfer is added on the basis of the original blade, so that over-cutting is avoided.
Die forging wing rail bed bottom slope milling cutter still includes a plurality of damping gasket 8, all is equipped with damping gasket 8 between every blade and the blade disc 1, and damping gasket 8 is the open box body structure of upper end and front end, is convenient for cover on every of blade and blade disc 1 contact. The damping of the blade is changed, and the vibration reduction effect is achieved. The milling cutter is more stable to process.
