Abstract
The invention discloses a cutting blade for processing soft metal materials. The cutting blade comprises an upper surface, a lower surface, a pair of side faces and a blade body which is enclosed by a conical surface for connecting the pair of side faces. The blade body is provided with a blade positioning hole, and the upper surface and the lower surface are connected through the pair of side faces and the conical surface. The conical surface and the upper surface are intersected into a main cutting edge, and the two side faces and the upper surface are intersected into two side cutting edges which are respectively connected on two sides of the main cutting edge. The upper surface is sunk toward the lower surface to form a rake face, a concave curved surface for guiding chips and more than two chip breakers in a shape of an elliptical lug boss. The chip breakers are uniformly distributed in a height increasing stepped shape from a position close to the main cutting edge to the blade positioning hole. The concave curved surface is connected between two adjacent chip breakers; and the rake face extends toward the middle of the upper surface from the main cutting edge and two side cutting edges, and is connected with the concave curved surface. The cutting blade has the advantages of controlling shapes and flow directions of the chips, decreasing the contact between the chips and the upper surface of the blade, and reducing the cutting temperature.
Description
Technical field
The present invention relates to a kind of metal cutting and use turning insert, relate in particular to the cutting tip that is used for soft metal materials processing.
Background technology
Be directed to and generally have a sharp anterior angle and a chip removal space in the turning insert structure of soft metal materials processing, be connected with a plane or an arc surface between rake face and the chip removal platform in this class formation with big opening.When cut, smear metal is positioned at the cutting edge excision of insert tip, slides plane or the arc surface that is connected to the chip removal platform along rake face then, discharges through the chip removal platform more like this.For the soft metal material; In process, can obtain an initial bending, smear metal possibly moved extension along rake face at the chip removal platform with integral form, and curling naturally dropping; Cutting temperature is raise; For the processing of soft metal material, smear metal and rake face contact and the rising of cutting temperature can make smear metal cohere on the rake face of blade, cause the actual processing anterior angle of blade to change.In this process to the curling of smear metal, control or prevision that the flow direction of smear metal and smear metal and contacting of rake face can't be artificial, smear metal also is difficult to fracture, and causes smear metal to be twined each other, damages the finished work surface and causes product glossiness not reach requirement.
In the prior art; Cutting tip with improvement back chip breaker is disclosed like U.S. Pat 6217264B1; It has given control to smear metal with contacting of rake face at chip removal platform place; Can reduce cutting temperature, but its point of a knife place does not have that to draw bits structure and point of a knife too level and smooth with being connected of rake face, in cutting process, do not give better controlled the curling and flow direction of smear metal.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes prior art, provide a kind of shape of controlling smear metal with the flow direction, reduce that smear metal contacts with the upper surface of blade, the cutting tip that is used for soft metal materials processing of cutting temperature reduction.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of cutting tip that is used for soft metal materials processing; Comprise by upper surface, lower surface, a pair of side and connect this blade body that taper seat surrounded the side; Said blade body is provided with the blade locating hole; Said upper surface is connected with taper seat the side through this with lower surface, and taper seat and upper surface intersect the formation main cutting edge, and two sides and upper surface intersect two side cutting edges that formation is connected to the main cutting edge both sides; Said upper surface caves in to lower surface; Two above chip breakers that form rake face, are used for the concave curved surface of directs chips and are oval boss shape, said chip breaker is from being the stepped even distribution that highly increases progressively near the main cutting edge place to the blade locating hole, and said concave curved surface is connected between adjacent two chip breakers; Said rake face extends to upper surface middle part from main cutting edge and two side cutting edges, and joins with concave curved surface.
The interlude of adjacent two chip breakers is connected with protruding cylinder surface, and the protruding cylinder surface both sides directly join with concave curved surface and perhaps join through transition plane and concave curved surface.
Be 0.1mm～0.8mm near the chip breaker of main cutting edge to the shortest horizontal range b of said main cutting edge peak, the shortest vertical range c is 0.03mm～0.36mm.
Be 0.02mm～0.15mm near the chip breaker peak of main cutting edge to the vertical range e of rake face.
The difference in height d of adjacent two protruding cylinder surfaces is 0.02mm～0.2mm before and after the said chip breaker.
The vertical range f of said chip breaker least significant end and sides adjacent cutting edge is 0.1mm～1.2mm.
Vertical vertical section angle θ of the rake face at said side cutting edge place and blade is 70 °～75 °.
The volume bits angle η that the rake face at said side cutting edge place and chip breaker form is 130 °～160 °.
Compared with prior art; The invention has the advantages that: upper surface caves in to lower surface; Two above chip breakers that form rake face, are used for the concave curved surface of directs chips and are oval boss shape; Concave curved surface and chip breaker form along slip-stream linearly lead, the chip removal structure, make that smear metal is curling naturally with chip breaker guiding back through concave curved surface, cut-out, be directed, discharge machining area smoothly; Chip breaker is from being the stepped even distribution that highly increases progressively to the blade locating hole near the main cutting edge place; Can reduce contacting of smear metal and blade upper surface; Thereby reduce the friction of smear metal and blade upper surface, reduce cutting temperature effectively, thereby prolonged the service life of blade.The interlude of adjacent two chip breakers is connected with protruding cylinder surface; Protruding cylinder surface both sides and concave curved surface join; This protruding cylinder surface can make smear metal nature to the deflection of protruding cylinder surface both sides; Help smear metal and discharge from the blade both sides smoothly, avoid smear metal to drop on processed surface of the work, thereby improve crudy.Main cutting edge of the present invention is higher than the side cutting edge, is space multistory and distributes, and has increased the contact area of cutting edge and workpiece; Be convenient to excise swimmingly workpiece material, make point of a knife have enough intensity again simultaneously, cut brisk; Accelerate cutting speed, improved production efficiency.
