Abstract
The utility model relates to a milling cutter blade with a wearing groove and radiating strips, which is a multilateral milling cutter blade and is characterized in that a wearing groove formed by inwards depressing the milling cutter blade is arranged behind a main cutting edge of each side and is an inclined groove forming a 20-30-degree inclined angle with the main plane of the milling cutter blade, the end of the inclined groove is close to the center of the multilateral milling cutter blade, and the end of the inclined groove is in the shape of a circular arc and is connected with the main plane of the blade; and the inclined surface of the wearing groove is at least provided with more than two strip-shaped wearing radiating strips, two ends of each wearing radiating strip are in a circular arc shape, the wearing radiating strips are arranged in parallel along the scrape discharging direction of the blade and are raised strips protruding out of the inclined surface of the wearing groove.
Description
Technical field
The utility model relates to a kind of machinery tools, particularly relates to a kind of cutter blade that is used for Milling Process, mainly uses the indexable machine folder milling cutter that milling is used.
Background technology
Milling Process is a kind of very common machining mode in the machining, so-called Milling Process utilizes milling cutter exactly on milling machine, carries out machining by the rotation of milling cutter, in Milling Process, get well and the evil idea of milling cutter are very important key links in the whole Milling Process.The kind of milling cutter is a lot, and structure differs, and is of wide application, and can comply with its job specification, device mode, cutting tool shape, structure, material, disc sharpener mode and sort out.Wherein according to being divided into according to structural classification:
1, Integral milling cutter: this type of milling cutter is made with identical material till the blade end from body, mostly is the high-speed steel material greatly, and majority is the milling cutter of the less or special shape of diameter, as end mill(ing) cutter, profile milling cutter, woodruff key slotting cutter etc.
2, weld tabs milling cutter: the carbon tool steel of shank and this body and function cheapness, blade and last high-speed steel or carbide.
3, dummy slider milling cutter: blade is employed on cutter hub with screw or intermediate plate folder.
Indexable milling cutter described in the utility model belongs to a kind of dummy slider milling cutter exactly, because the main cutting edge of indexable milling cutter part is partly separated with cutter hub, main cutting edge partly is a disposable type, and use different blades by transposition, reached best economy, so present many professional Digit Control Machine Tool all is to adopt indexable milling cutter.But existing indexable milling cutter, particularly face-milling insert be the trough of belt type scarcely, is plane polishing processing (seeing accompanying drawing 1).In working angles, it is serious to rub between smear metal and the blade rake face, and main cutting force is bigger, thereby produces bigger grinding heat, has reduced the service life of this type of blade widely, and has caused bad workpiece to be machined surface quality.Therefore necessary this is solved.
The utility model content
The purpose of this utility model provides a kind of in working angles in order to overcome the deficiency of existing indexable milling cutter, between smear metal and the blade rake face friction littler, relative main cutting force is also littler, the few novel indexable milling cutter of the grinding heat that produces; This kind milling cutter can prolong the service life of blade, improves the workpiece to be machined surface quality.
The purpose of this utility model is achieved through the following technical solutions, a kind of anti-attrition groove and heat sink strip cutter blade of having, be polygon-shaped cutter blade, behind the main cutting edge on each limit, have the anti-attrition groove that caves inward by cutter blade, the anti-attrition groove is the oblique groove that becomes 20-30 degree oblique angle with the cutter blade principal plane downwards, the end of oblique groove is near the center of polygon-shaped cutter blade, and the end of oblique groove is circular-arc and the blade principal plane joins; At the anti-attrition heat sink strip that is provided with at least on the inclined-plane of anti-attrition groove more than 2, the anti-attrition heat sink strip is a strip, and two is circular-arc, and the anti-attrition heat sink strip is arranged in parallel according to the direction that blade goes out bits, and for giving prominence to the raised line on anti-attrition groove inclined-plane.
The beneficial effects of the utility model are: indexable milling cutter provided by the utility model has anti-attrition groove, the indexable cutter blade of heat sink strip, the shortcoming that just is being based on above-mentioned this type of blade existence designs, improved the friction of smear metal and blade rake face well, reduce the heat in metal cutting that frictional force and main cutting force are produced, improved the service life and the machining quality of blade significantly.

Among the figure: 1, indexable milling cutter sheet, 2, main cutting edge, 3, the anti-attrition groove, 4, the cutter blade principal plane, 5, circular-arc, 6, the anti-attrition heat sink strip.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment one
Shown in Fig. 1-5, a kind of anti-attrition groove and heat sink strip cutter blade of having is indexable milling cutter sheet 1, and indexable milling cutter sheet 1 is tetragonal laminated structure; Behind the main cutting edge 2 on each limit, have the anti-attrition groove 3 that caves inward by cutter blade, the anti-attrition groove is the oblique groove that becomes 20-30 degree oblique angle with cutter blade principal plane 4 downwards, the end of oblique groove is near the center of polygon-shaped cutter blade, and the end of oblique groove is circular-arc 5 to join with blade principal plane 4; At the anti-attrition heat sink strip 6 that is provided with at least on the inclined-plane of anti-attrition groove 3 more than 2, the anti-attrition heat sink strip is a strip, and two is circular-arc, and anti-attrition heat sink strip 6 is arranged in parallel according to the direction that blade goes out bits, and for giving prominence to the raised line on anti-attrition groove inclined-plane.
In working angles, (2～3GPa) is bigger, and chip surface makes smear metal bottom and rake face that the phenomenon that bonds take place up to the high temperature of several Baidu simultaneously owing to the pressure between smear metal and the rake face.Under the bonding situation, the friction between smear metal and the rake face is not general external friction, but the interior friction between smear metal and cutter tack coat, the tool surface metal.The blade of band anti-attrition groove is owing to the little frictional force that makes of contact area of smear metal and rake face reduces.
Under all identical situation of other parameter of processing conditions and blade, the main cutting force of band anti-attrition slot blade is littler than the corresponding not main cutting force with the anti-attrition slot blade, the blade of band anti-attrition groove can effectively reduce contact area, the frictional force of smear metal and bottom land is reduced, thereby reduce main cutting force.The result of cutting test shows: have indexable the breaking of anti-attrition groove and heat sink strip flute profile and cut the slotting cutter sheet, effect is better in roughing and semifinishing.
Embodiment two
A kind of anti-attrition groove and heat sink strip cutter blade of having is the indexable milling cutter sheet, and its characteristics are: the indexable milling cutter sheet is the laminated structure of triangle, and other is the same with embodiment one.
