Abstract
The invention relates to the technical field of mechanical cutters, and in particular to an irregular lace milling cutter. An annular cutter withdrawing groove is formed in a cutter handle at the connecting part of the cutter handle and a cutter head; a first annular groove and a second annular groove are formed in sequence from the front end to the bottom end of the cutter head in the circumferential direction of the cutter head in the radial direction; the cross sections of the first annular groove and the second annular groove are arc-shaped; V-shaped grooves are formed in two opposite sides of the circumferential surface of the cutter head; a cutting part is formed at the conical cutter head between the V-shaped grooves; cutting blades are arranged at the joint parts of the side walls of the V-shaped grooves and the cutting part; arc-shaped chip spaces are formed in the V-shaped grooves; the chip spaces are positioned in the arc-shaped surfaces of the V-shaped grooves. The irregular lace milling cutter is high in processing precision and convenient in processing irregular laces.
Description
Technical field
The present invention relates to machinery knives technical field, particularly relate to special-shaped lace milling cutter.
Background technology
Along with the development of modern industry, electronics technology is also more and more flourishing, and the required precision of electronic product is also more and more higher, and the requirement of the especially material cutting such as acryl, density board, aluminium sheet also improves thereupon; At present when the sidewall processing the materials such as density board, acryl, aluminium sheet has the v-depression of curved flanges, adopt general milling cutter not only processing difficulties, and when the quantity of curved flanges is more, general milling cutter is adopted to need repeatedly to repeat tool setting tool changing, cause recess sidewall smoothness not high, and precision is low.
Summary of the invention
The object of this invention is to provide a kind of machining accuracy high, be convenient to the special-shaped lace milling cutter processed.
Technical scheme of the present invention is as follows:
Abnormity lace milling cutter, comprise handle of a knife, handle of a knife connects the cutter head of bullet, and the handle of a knife of described handle of a knife and cutter head junction is provided with annular escape; Described cutter head periphery is radially provided with first ring connected in star and the second annular groove successively from cutter head front end to bottom, and this first, second annular groove cross section is curved; Described cutter head periphery two opposite face is equipped with " V " connected in star, and the tapered knife capitiform between " V " connected in star becomes cutting portion; The junction of described " V " connected in star sidewall and cutting portion forms cutting edge; Described " V " connected in star is provided with the chip area of arc, and this chip area is positioned on the arc surface of " V " connected in star.
Described cutter head welds with adopting between handle of a knife; Described handle of a knife adopts No. 45 steel, and cutter head adopts wolfram steel material.
The limit, outer of described cutter head bottom is provided with chamfered section, and this chamfered section side is provided with chamfering blades.
Described cutter head front end face is provided with shear blade.
The invention has the beneficial effects as follows: by arranging first, second annular groove, and first, second annular groove cross section is curved, in milling process, can milling " V " connected in star, make groove side wall form curved flanges simultaneously; Due to the tapered body of cutter head, and the junction of " V " connected in star sidewall and cutting portion forms cutting edge, realizes the milling of " V " connected in star.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is handle of a knife, and 2 is cutter head, and 3 is annular escape, and 4 is first ring connected in star, and 5 is the second annular groove, and 6 is " V " connected in star, and 7 is cutting edge, and 8 is chip area, and 9 is chamfered section, and 10 is chamfering blades, and 11 is shear blade.
Detailed description of the invention
Embodiment 1
Shown in Figure 1, special-shaped lace milling cutter, comprises handle of a knife 1, and handle of a knife connects the cutter head 2 of bullet, and the handle of a knife of described handle of a knife and cutter head junction is provided with annular escape 3; Described cutter head periphery is radially provided with first ring connected in star 4 and the second annular groove 5 successively from cutter head front end to bottom, this first, second annular groove cross section is curved; Described cutter head periphery two opposite face is equipped with " V " connected in star 6, and the tapered knife capitiform between " V " connected in star becomes cutting portion; The junction of described " V " connected in star sidewall and cutting portion forms cutting edge 7; Described " V " connected in star is provided with the chip area 8 of arc, and this chip area is positioned on the arc surface of " V " connected in star.
By arranging first, second annular groove, and first, second annular groove cross section is curved, in milling process, can milling " V " connected in star, and make groove side wall form curved flanges simultaneously; Due to the tapered body of cutter head, and the junction of " V " connected in star sidewall and cutting portion forms cutting edge, realizes the milling of " V " connected in star.
Embodiment 2
On the basis of embodiment 1, described cutter head welds with adopting between handle of a knife; Described handle of a knife adopts No. 45 steel, and cutter head adopts wolfram steel material.Weld because handle of a knife adopts with cutter head, be conducive to handle of a knife and adopt different materials from cutter head, reduce the production cost of special-shaped lace milling cutter; Wherein handle of a knife adopts No. 45 steel costs comparatively cheap; And cutter head adopts wolfram steel material, hardness is high, wearability good, tool life.
Embodiment 3
On the basis of embodiment 1, the limit, outer of described cutter head bottom is provided with chamfered section 9, and this chamfered section side is provided with chamfering blades 10.Owing to arranging chamfered section and chamfering blades, be conducive to directly carrying out chamfering after milling completes, avoid repetition tool changing tool setting, save process time.
Embodiment 4
On the basis of embodiment 1, described cutter head front end face is provided with shear blade 11.Because cutter head front end arranges shear blade, be conducive to when milling " V " connected in star, to the milling of groove floor, improve the surface flatness of bottom surface.
Embodiment 5
On the basis of embodiment 1, described cutter head is coated with diamond dust.Due to cutter head being coated with diamond dust, thus increase cutter head intensity and hardness, further tool life.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention, every according in technical spirit of the present invention to any simple modification, equivalent variations that above embodiment is done, all fall within protection scope of the present invention.
