Description
Technical field
The present invention relates to the metal cutting manufacture field, but relate in particular to circular cutter blade of transposition and milling cutter.
Background technology
The milling tool that is used for the metal chip removing machining generally includes rotatable milling cutter main body (usually most of for steel), and the milling cutting insert of materials such as a plurality of removable carbide alloy, pottery.The milling tool that the milling cutter main body of circular cutter blade and correspondence is formed based on himself characteristic, is applied to die cavity processing usually, and copying, plane processing etc. are used very extensive.
The available cutting edge of circular cutter blade is all on blade circumference sword; Roughly judge the blade access times according to cutting output; Do not have fixing cutting edge number, the normally fairly simple two-dimentional grooved of traditional circular cutter blade cutting blade structure design comprises consistent land structure; Consistent cutting anterior angles etc., the actual cut situation to circular cutter blade does not adjust to grooved.In the actual cut processing, the corresponding actual cut thickness of lip height that circular cutter blade is participated in cutting is different, and the actual cut one-tenth-value thickness 1/10 of the big more correspondence of lip height value is big more.Cutting speed, cutting-in, feeding, anterior angle, edge strength all have considerable influence to the damage of circular cutter blade cutting edge; The area relative thickness of cutting that the lip height value is big during actual cut is big; And traditional circular cutter blade complete cycle cutting blade structure is consistent; Obviously is irrational to the distinct cutting situation with same cutting structure, and the cutting edge region here is relatively easy, and improper damage takes place, thereby influences the service life of cutter.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes prior art, but a kind of circular cutter blade of transposition that can effectively prevent the local abnormal spoilage of cutting edge, increase the service life is provided, but and milling cutter with the circular cutter blade of this transposition.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
But the circular cutter blade of a kind of transposition; Comprise upper surface, lower surface and the back knife face between upper surface and lower surface; Said upper surface is provided with cutting edge zone face and smear metal spigot surface, and said back knife face is provided with side, a plurality of location, but said cutting edge zone face intersects the cutting edge that forms a plurality of alternate application with the back knife face; Actual cut thickness maximum is the cutting edge leading section on the said cutting edge, and the minimum place of actual cut thickness is the cutting edge bottom on the said cutting edge; In each cutting edge place, the direction along the cutting edge bottom towards the cutting edge leading section, the width of said cutting edge zone face broadens gradually, and the angle that said cutting edge zone face and smear metal spigot surface form reduces gradually, and the effective width of said smear metal spigot surface increases gradually.
Said cutting edge is 4 to 10.
The side, location that is provided with on the knife face of said back is corresponding one by one with cutting edge.
A kind of milling cutter comprises cutter hub, but is equiped with the circular cutter blade of above-mentioned transposition on the said cutter hub.
Compared with prior art, the invention has the advantages that:
But the circular cutter blade of transposition of the present invention, but the cutting edge zone face intersects the cutting edge that forms a plurality of alternate application with the back knife face, is the cutting edge leading section with actual cut thickness maximum on the cutting edge; Minimum place is the cutting edge bottom with actual cut thickness on the cutting edge; In each cutting edge place, the direction along the cutting edge bottom, the actual cut thickness variation tendency from small to large of just pressing cutting edge towards the cutting edge leading section; The width of cutting edge zone face broadens gradually; Edge strength is strengthened gradually, and the angle that cutting edge zone face and smear metal spigot surface form increases gradually, and cutting edge actual cut anterior angle is increased gradually; The cutting force that produces than the big part of existing circular cutter blade actual cut thickness reduces relatively; The effective width of smear metal spigot surface increases gradually, thereby according to the difference of actual cut thickness the chip curling radius is realized accurately control, is more conducive to chip breaking, chip removal, heat radiation in the working angles; But the circular cutter blade of transposition of the present invention is according to the variation characteristic of cutting edge actual cut thickness; Cutting edge structure has been done above-mentioned improvement; Make cutting edge width, actual cut anterior angle, volume bits platform width obtain effective and reasonable adjustment; When promoting the cutting edge cutting ability, make cutting edge be in a kind of state of relative equilibrium, thereby can effectively prevent the local abnormal spoilage of cutting edge, prolong blade service life.The side, location that is provided with on the back knife face is corresponding one by one with cutting edge, when being convenient to be installed on blade on the cutter hub cutting edge is accurately located.Milling cutter of the present invention, but on cutter hub, be equiped with the circular cutter blade of above-mentioned transposition, but because the circular cutter blade of above-mentioned transposition has above-mentioned technique effect, this milling cutter also has the corresponding techniques effect.
