Abstract
The utility model discloses a circular arc grooving tool capable of efficiently breaking chips for machining aluminum alloy. A tool bit of the grooving tool is provided with six chip breaking bosses; the chip breaking bosses are circular arc-shaped and are uniformly arranged and distributed on the upper surface of the tool bit along a cutting edge track of the tool bit; the cutting edge of the tool bit is in a convex circular arc shape; the cutting edge of the tool bit and the front end of the tool bit form an included angle of 15-20 degrees backwards opposite to the vertical direction; and the cutting edge of the tool bit and the upper surface of the tool bit form an included angle of 8-10 degrees downwards opposite to the horizontal direction. Large cutting front angle and rear angle are designed for the cutting edge of the tool bit, so that sharpness of the cutting edge of the tool bit is guaranteed, and the friction with a workpiece during machining is reduced; the novel chip breaking bosses are designed in the center of the tool bit, so that the contact area of aluminum chips and the blade is reduced, thereby avoiding heat transfer of the aluminum chips to the blade; the design of the bosses also has a good chip breaking effect, and the heat of the tool is also reduced; and thus, the phenomenon of adhesion or breakage of the tool is effectively avoided, and the machining accuracy and the degree of finish of the surface of the workpiece are improved.
Description
Technical field
The utility model relates to a kind of metal processing cutting tool, and the circular arc grooving cutter is used in the aluminium alloy processing that relates in particular to a kind of efficient chip breaking.
Background technology
The cutter that the processing aluminium alloy needs requires cutting edge sharp especially; Eliminate sticking cutter phenomenon to reduce the rake face friction, simultaneously because aluminum alloy materials is softer, the aluminium bits are not easy fracture; Add man-hour aluminium bits at grooving and hold to be entangled in easily and influence machined surface quality and precision on the cutter, even cause breaking.
Summary of the invention
The purpose of the utility model provides a kind of aluminium alloy processing of efficient chip breaking to use the circular arc grooving cutter with regard to being in order to address the above problem.
The utility model is realized above-mentioned purpose through following technical scheme:
The cutter head of the said grooving cutter of the utility model is provided with the chip breaking boss; Said chip breaking boss is six and to be the cutting edge track of the said cutter head in circular-arc edge evenly distributed in the upper surface of cutter head; The cutting edge of said cutter head is an evagination circular arc; Be 15 ° to 20 ° angle after the cutting edge of said cutter head and said cutter head front end lean on vertical direction, the cutting edge of said cutter head and the upper surface of said cutter head are 8 ° to 10 ° angle downwards with horizontal direction.
Particularly, the cutting edge of said cutter head and said cutter head front end are 17 ° angle, and the cutting edge of said cutter head and the upper surface of said cutter head are 9 ° angle; The length of said chip breaking boss and wide ratio are 1: 2; Said cutter head is two and is positioned at the two ends of cutter hub.
The beneficial effect of the utility model is:
The cutter edge of the utility model has designed bigger cutting anterior angle and relief angle, and is sharp to guarantee cutter head smear metal cutting edge, reduces the friction that adds man-hour and workpiece; At the novel chip breaking boss of cutter head central design; The height of boss, size are through computer simulation design; Make smear metal produce the appropriateness distortion and fracture to reach, reduce the contact area of aluminium bits and blade, thereby avoid aluminium bits heat transferred blade; The design of boss not only has good chip breaking effect, also reduces the cutter heat; But but not only grooving but also turning, and, have very good chip breaking effect through the turning experimental verification, thus effectively avoided the phenomenon of sticking cutter or breaking, improved the machining accuracy and the fineness of surface of the work.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4: the cutter head of the said grooving cutter of the utility model is provided with the chip breaking boss; Said chip breaking boss is six and to be the cutting edge track of the said cutter head in circular-arc edge evenly distributed in the upper surface of cutter head; The cutting edge of said cutter head is an evagination circular arc; Be 15 ° to 20 ° angle after the cutting edge of said cutter head and said cutter head front end lean on vertical direction, the cutting edge of said cutter head and the upper surface of said cutter head are 8 ° to 10 ° angle downwards with horizontal direction.
Like Fig. 1, Fig. 3 and shown in Figure 4: the cutting edge of said cutter head and said cutter head front end are 17 ° angle, and the cutting edge of said cutter head and the upper surface of said cutter head are 9 ° angle; The length of said chip breaking boss and wide ratio are 1: 2; Said cutter head is two and is positioned at the two ends of cutter hub.This blade adopts rectangular dual head design; α is 17 ° of angles of blade, and cutting edge has 9 ° of anterior angles (β among the figure) and guaranteed the sharp of cutting edge and the friction that has reduced with workpiece, half of the about L2 of L1 among Fig. 3; More help the discharge and the fracture of cutting; Smear metal when L1 is too high, possibly occur and curl towards the workpiece direction and tipping excessively occurs, when L1 crosses when low, the little and easy fracture not of chip deformation.
When cutting blade radially during feed (directions X) be circular arc because of cutting edge; Avoided the friction with workpiece, improved workpiece surface finish, made workpiece surface quality higher; When cutter shaft is that a contact is reduced friction during to (Y direction) feed, can also carry out copying simultaneously.
