Because the utility model discloses an evenly distributed has many to mill the cutting edge on the milling cutter head circumference side, and two adjacent helical angles that mill the cutting edge are different, and milling cutter possess the helical angle of two kinds of differences of size simultaneously, and the design of this kind of mixed helical angle for milling cutter has the performance of two kinds of helical angles concurrently, has that the cutting force is big, the easy advantage of chip removal.
Description
Technical Field
The utility model relates to a cutter especially relates to a mix spiral angle milling cutter.
Background
The component of milling in the field of machining is becoming more and more important, and has gradually replaced other machining methods such as turning, drilling and the like to some extent. Milling cutters are rotary tools for milling operations having one or more cutting teeth, and are used primarily for machining surfaces, steps, grooves, formed surfaces, and cutting workpieces, where the cutting teeth (edges) are used to intermittently cut off the workpiece in sequence. As shown in fig. 1, the milling cutter 1 ' has a milling cutting edge 11 ' with only one helix angle a ', which has a great influence on the performance of the milling cutter, the larger the helix angle a ', the greater the radial cutting force of the milling cutter, but the harder the chip removal, and the smaller the helix angle a ', the easier the chip removal of the milling cutter.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a big, the easy mixed spiral angle milling cutter of chip removal of cutting force.
In order to achieve the above object, the technical solution of the present invention is:
the utility model relates to a mixed helical angle milling cutter, which comprises a milling cutter rod and a milling cutter head; the milling head is connected with the milling cutter rod, the milling head and the milling cutter rod are coaxially arranged, and the milling head and the milling cutter rod are integrated members; the milling cutter is characterized in that a plurality of milling cutting edges are uniformly distributed on the circumferential side surface of the milling cutter head, and the spiral angles of two adjacent milling cutting edges are different.
Six milling cutting edges are uniformly distributed on the circumferential side surface of the milling cutter head, the spiral angles of the first, third and fifth milling cutting edges are the same, the spiral angles of the second, fourth and sixth milling cutting edges are the same, and the spiral angles of the first, third and fifth milling cutting edges are different from the spiral angles of the second, fourth and sixth milling cutting edges.
The angle difference of the spiral angles of the two adjacent milling cutting edges is 2-10 degrees.
After the technical scheme is adopted, because the utility model discloses an evenly distributed has many to mill the cutting edge on the milling cutter head circumference side, and two adjacent helical angles that mill the cutting edge are different, and milling cutter possess the helical angle of two kinds of differences of size simultaneously, and the design of this kind of mixed helical angle for milling cutter has the performance of two kinds of helical angles concurrently, has that the cutting force is big, the easy advantage of chip removal.
The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description
As shown in fig. 2 and 3, the present invention relates to a hybrid helical angle milling cutter, which comprises a milling cutter rod and a milling cutter head. The milling head is connected with the milling cutter rod, the milling head and the milling cutter rod are coaxially arranged, and the milling head and the milling cutter rod are integrated components. The side surface of the circumference of the milling cutter head 1 is uniformly distributed with a plurality of milling cutter edges 11, the helical angles a1 and a2 of two adjacent milling cutter edges 11 and 12 are different, and the angle difference is 2-10 degrees.
In this embodiment, six milling blades are uniformly distributed on the circumferential side surface of the milling head 1, the helix angles a1 of the first, third and fifth milling blades 11 are the same, the helix angles a2 of the second, fourth and sixth milling blades 12 are the same, and the helix angle a1 of the first, third and fifth milling blades 11 is smaller than the helix angle a2 of the second, fourth and sixth milling blades 12. The utility model discloses a course of working:
as shown in fig. 4, first, third and fifth milling blades 11 with smaller helix angle a1 are firstly processed, and the circumferential radii of the three milling blades are the same and are R1;
as shown in fig. 5, the second, fourth and sixth milling blades 12 with larger helix angle a2 are reprocessed, and the circumferential radius of the 3 blades is the same and is R2; the radius of the circumferential edge of the stroke must not be the same because of the different helix angles, i.e. R1 ≠ R2;
as shown in fig. 6, it is preferable to form the desired milling head 1 by machining milling blades of both R1 and R2 radii to the same radius R3 to finally obtain the end blade shape as shown in fig. 3.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
