Abstract

The utility model discloses a mixed groove deep 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; a plurality of spiral peripheral blades which extend along the axial direction of the milling cutter head are uniformly distributed on the circumferential side surface of the milling cutter head, and each peripheral blade is provided with a front blade surface and a rear blade surface; be provided with the ditch depth between two adjacent week swords, this ditch depth is the heliciform along tool bit axial extension with week sword unanimity, and the back blade surface of the adjacent week sword of the preceding blade surface of arbitrary week sword and anticlockwise passes through the circular arc transition and forms the chip removal ditch, and the ditch depth of two adjacent chip removal ditches is different. Because the utility model discloses two adjacent ditch of milling cutter are different and be separated by the deep degree of depth of ditch the same, use two kinds of ditches deeply on same milling cutter for milling cutter has the deep performance characteristics of two kinds of ditches concurrently, has the good advantage of a sharpness, wearability and rigidity.

Description

mixed groove deep milling cutter

Technical Field

The utility model relates to a cutter especially relates to a mix dark milling cutter in ditch.

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. The cutting sharpness of the milling cutter is determined by a rake angle alpha, the larger the rake angle, the sharper the milling cutter is; the clearance angle beta affects the wear resistance of the peripheral blade, and the smaller the clearance angle is, the more wear-resistant the blade is; the groove is deep, namely a chip removal space, the larger the groove depth is, the larger the chip removal space is, the less chips are blocked, the cutting resistance is small, meanwhile, the deeper the groove depth is, the front angle is large, the rear angle is also larger, the milling cutter is very sharp, but the wear resistance is reduced. The depth of the groove is small, the chip discharging space is small, the chips are easy to block, the front angle and the rear angle are small, but the thickness of the cutter body core is large, the rigidity of the cutter body is better, the two types of grooves have advantages and disadvantages when being deep enough, and how to enable the milling cutter to have the performance advantages of a deep groove and a shallow groove is a problem to be considered by an operator.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a mixed dark milling cutter of ditch that sharpness, wearability and rigidity are good.

in order to achieve the above object, the technical solution of the present invention is:

The utility model relates to a mixed groove deep 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; a plurality of spiral peripheral blades which extend along the axial direction of the milling cutter head are uniformly distributed on the circumferential side surface of the milling cutter head, and each peripheral blade is provided with a front blade surface and a rear blade surface; be provided with the ditch depth between two adjacent week swords, this ditch depth is the heliciform with week sword unanimously and extends along the tool bit axial, and the back blade surface of the adjacent week sword of counter-clockwise direction and the preceding blade surface of arbitrary week sword passes through the circular arc transition and forms the bits ditch, and the ditch depth of two adjacent bits of discharge ditch is different.

Six milling peripheral edges and six groove depths are uniformly distributed on the circumferential side surface of the milling cutter head in a spiral shape, the depths of the first, third and fifth groove depths are the same, the depths of the second, fourth and sixth groove depths are the same, and the depths of the first, third and fifth groove depths are different from the depths of the second, fourth and sixth groove depths.

after the scheme is adopted, because the utility model discloses the degree of depth that two adjacent ditches of milling cutter are dark is different and the degree of depth that is separated by the ditch is the same, and the rake face that three zanjon corresponds has great anterior angle, and the cutting sharpness is strong, and the back knife face that three shallow ditch corresponds has less relief angle, and wearability and rigidity are good. The milling cutter has the advantages of good sharpness, wear resistance and rigidity.

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description

As shown in fig. 1, the utility model relates to a mixed groove deep milling cutter, which comprises a milling cutter rod and a milling cutter head 1; the milling cutter head 1 is connected with the milling cutter rod, the milling cutter head 1 and the milling cutter rod are coaxially arranged, and the milling cutter head 1 and the milling cutter rod are integrated.

A plurality of spiral peripheral blades 11 which extend along the axial direction of the milling cutter head are uniformly distributed on the circumferential side surface of the milling cutter head 1, and the peripheral blades 11 are provided with a front blade surface A and a rear blade surface B; a groove depth 12 is arranged between two adjacent peripheral blades 11, the groove depth 12 and the peripheral blades 11 are consistent and extend along the axial direction of the cutter head in a spiral shape, the front blade surface of any peripheral blade 11 and the rear blade surface B of the adjacent peripheral blade 11 in the anticlockwise direction form chip grooves through arc transition, and the groove depths of the two adjacent chip grooves are different.

In this embodiment, six circumferential edges 11 and six groove depths 12 are uniformly distributed on the circumferential side surface of the milling head 1 in a spiral shape, the depths of the first, third and fifth groove depths 121 are the same as deep grooves, and the front angle and the rear angle of the corresponding circumferential edge 11 are α 1 and β 1 respectively; the depth of the second, fourth and sixth grooves 122 is the same as the shallow groove, and the front α 2 of the corresponding peripheral edge 11 is smaller than α 1, and the back angle β 2 is smaller than β 1; the first, third and fifth groove depths 121 are different from the second, fourth and sixth groove depths 122.

The utility model discloses a course of working:

As shown in fig. 2, first, third and fifth deeper groove depths 121 are processed;

as shown in fig. 3, the second, fourth, and sixth groove depths 122, which are shallower in rework depth;

As shown in fig. 4, the desired milling head 1 is finally produced.

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.
