Abstract

The utility model belongs to the technical field of the milling cutter technique and specifically relates to a highlight crew cut milling cutter, is applicable to and cuts highlight outward appearance piece, including on the handle of a knife, handle of a knife on fashioned tool bit, the tool bit shaping have helical shape zhou ren, the axial one end of tool bit is connected on the handle of a knife, and the other end forms the terminal surface, and zhou ren's blade tip is for falling round angle structure. The round angle structure that falls through the blade tip makes the blade tip smoothly not have the breach, satisfies aluminium alloy product's surperficial highlight quality requirement, can make cutting process more steady through the shock attenuation area, eliminate shake sword phenomenon, the shock attenuation area can also strengthen blade intensity in addition to carry out the sleeking effect to the product finished surface.

Description

High light flat-end cutter

Technical field

This utility model relates to milling cutter technical field, especially a kind of high light flat-end cutter, it is adaptable to cut high light appearance member.

Background technology

Milling cutter, for Milling Process, the rotary cutter with one or more cutter tooth, during work, each cutter tooth cuts the surplus of workpiece successively off and on.

At present, the granule that milling cutter skive in working angles is announced in a jumble makes carbide tool blade tip microcosmic breach occur, microcosmic indentation, there very easily forms built-up edge, change tool nose shape, when processing alloy product, due to the cutting characteristic of aluminum alloy materials, thus adding quick-wearing, and enable aluminum alloy to machined surface and form open-wire line or dark stricture of vagina, it is impossible to meet the surface height light quality requirements of alloy product.

Being based on above-mentioned consideration, this utility model designs a kind of high light flat-end cutter, it is possible to remove the microcosmic breach of point of a knife, changes the microcosmos geometric shape of point of a knife, makes the smooth non-notch of tool nose.

Utility model content

The purpose of this utility model is in that to overcome the deficiencies in the prior art, adapts to reality need, it is provided that a kind of high light flat-end cutter.

In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:

A kind of high light flat-end cutter, including forming spiral Zhou Ren on the cutter head of molding, cutter head on handle of a knife, handle of a knife, axial one end of described cutter head is connected on handle of a knife, and the other end forms end face, and the blade tip of Zhou Ren is rounding structure.

The rounding radii R of described blade tip is 0.002mm ~ 0.05mm.

The quantity of described Zhou Ren is three, and with end face for initiating terminal right-hand screw to the other end end of cutter head, three starting points of described three Zhou Ren are uniformly distributed at the edge of end face, described three Zhou Ren annular arrays centered by the central axis of handle of a knife.

Described Zhou Ren is curve sword, and three Zhou Ren form chip area each other, and described chip area is the cambered surface of indent, by the rear knife face of the rake face of a Zhou Ren and adjacent another week sword around forming.

Described rake face and rear knife face are cambered surface, described cambered surface surface finish, and the roughness on described rake face (7) and rear knife face surface is less than 0.2 micron.

Major first flank that described rear knife face includes being connected with week sword, form chip area the 3rd after after knife face, major first flank and the 3rd between knife face second after knife face.

Described major first flank is additionally provided with lanyard.

The beneficial effects of the utility model are:

1., by the rounding structure of blade tip, make the smooth non-notch of blade tip, meet the surface height light quality requirements of alloy product；

2. working angles can be made more steady by lanyard, eliminate shake cutter phenomenon, and lanyard can also strengthen cutting edge strength, and Product processing surface is carried out smoothing effect.

Fig. 3 is the partial enlarged drawing of A in Fig. 2.

1 handle of a knife, 2 cutter heads, 3 weeks swords, 4 end faces, 5 blade tips, 6 chip areas, 7 rake faces, knife face after 8,81 major first flanks, knife face after 82 second, knife face after 83 the 3rd, 9 lanyards.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model preferred embodiment is further illustrated:

A kind of high light flat-end cutter, including handle of a knife 1, the cutter head 2 of molding on handle of a knife 1, cutter head 2 forms spiral all swords 3, axial one end of described cutter head 2 is connected on handle of a knife 1, the other end forms end face 4, the blade tip 5 of all swords 3 is rounding structure, it is rounding structure by blade tip 5, the microcosmic breach of blade tip 5 can be removed, change the microcosmos geometric shape of blade tip 5, make the smooth non-notch of blade tip 5, meet the surface height light quality requirements of alloy product, user handle of a knife 1 is fixed on milling machine, coordinated with the end sword on end face 4 by spiral week sword 3 and workpiece is carried out milling；By contrasting the high magnification map done before and after rounding structure, as preferred embodiment, the rounding radii R of described blade tip 5 is set to 0.002mm ~ 0.05mm, it is possible to meet the surface height light quality requirements of alloy product.

The quantity of described all swords 3 is three, with end face 4 for initiating terminal right-hand screw to the other end end of cutter head 2, three starting points of described three all swords 3 are uniformly distributed at the edge of end face 4, described three all swords 3 annular arrays centered by the central axis of handle of a knife 1, little area levels plane or profile finish-milling is had only to, so having only to adopt three all swords 3 as cutting edge due to the present embodiment；The helical structure of described all swords 3, it is possible to be left-hand screw or right-hand screw, owing to left-hand screw is higher to manufacturing technique requirent, adopts right-hand screw as the hand of spiral of week sword 3 as preferred the present embodiment, is suitable for more economically；Described all swords 3 are curve sword, three all swords 3 form chip area 6 each other, described chip area 6 is the cambered surface of indent, described chip area 6 by the rear knife face 8 of the rake face 7 of all sword 3 and adjacent another week sword 3 around forming, in the process of week sword 3 milling, by chip area 6 chip removal, the cambered surface of indent is easy to chip removal；Described rake face 7 and rear knife face 8 are cambered surface, described cambered surface surface finish, and the roughness on described rake face 7 and rear knife face 8 surface is less than 0.2 micron, and described rake face 7 and rear knife face 8 surface finish process and be conducive to the smooth and easy chip removal of chip area.

Major first flank 81 that described rear knife face 8 includes being connected with week sword 3, form chip area 6 the 3rd after after knife face 83, major first flank 81 and the 3rd between knife face 81 second after knife face 82, by multiple rear knife faces 7, milling cutter can be made to produce progressive abrasion, increase the service life of milling cutter；Being additionally provided with lanyard 9 on described major first flank 81, lanyard 9 can make working angles more steady, eliminates shake cutter phenomenon, and lanyard 9 can also strengthen cutting edge strength, and Product processing surface is carried out smoothing effect.
