Abstract
Mechanically clamped blade with multiple cutting edges belongs to the machine tool class.Chip width and the cutting edge of tradition cutting knife are wide equally, and not only main cutting force is big, heat in metal cutting height, and the smear metal resistance is also big, often since chip removal not freely and knife.
The multiple-cutting-edge cutting knife will be divided into two or three with the same wide smear metal of blade, and this not only reduces main cutting force, and has reduced the smear metal resistance greatly, has reduced heat in metal cutting, so the multiple-cutting-edge cutting knife is safety, and reliable, the life-span is long, the new-type cutter that cost is low.
Description
Mechanically clamped blade with multiple cutting edges belongs to the machine tool class.In machining, the kind of cutting knife is a lot, and the form of cutting edge is more, but numerous cutting knifes changes ten thousand times without leaving the original aim or stand.The width that is smear metal is identical with the width of joint-cutting, because extruding, in fact the width of smear metal is greater than the width of joint-cutting, so smear metal is very easy to be stuck in joint-cutting, causes knife, makes cutter hub impaired, and blade batters down, even workpiece is scrapped.The cutting knife that these are traditional, for cutter hub being enough to overcome the destruction of main cutting force, the width of having to increase cutter hub to be strengthening the drag to main cutting force, this not only power, the energy increase thereupon, more, cut metal is increased greatly because of increasing the width of blade.
Multiple-cutting-edge cutting edge of the present invention owing to be designed to two or three cutting edges, makes with the same wide smear metal of joint-cutting to be divided into two or three.Fig. 1 is the three-view diagram of multiple-cutting-edge cutting edge.Main cutting edge (1) stretches out certain length than paying cutting edge (2), make main cutting edge participate in cutting earlier, this equals with one narrower cutting knife to be cut out a narrower more shallow joint-cutting earlier, after using the cutting knife pad of a broad thereupon, make smear metal become two or three by one, and the main sword of cutting each has separately chip curling groove (3) and (4) with paying cutting edge, under the support of cutter hub (5), smear metal can not be become band and twines extruding each other.This cutting lay that breaks the whole up into parts distributes, and main cutting force is reduced, and smear metal resistance, heat in metal cutting all reduce thereupon greatly, corresponding main cutting force also reduces the moment of flexure of cutter hub, the cutter hub width of supporting blade also subtracts narrow, has not only reduced power consumption, the more important thing is and has saved a large amount of metals, compare with existing domestic and international cutting knife, the multiple-cutting-edge cutting knife is a safety, and reliable, the life-span is long, the new-type cutter that cost is low, promoting this cutting knife has remarkable social benefit and economic benefit.
Claims (2)
1, a kind of mechanically clamped blade with multiple cutting edges is characterized in that blade is made up of two or three main cutting edges and front cutting edge.
2, blade as claimed in claim 1 is characterized in that main cutting edge and front cutting edge all have chip curling groove.
