Abstract
The utility model discloses an improved cutting edge and a cutter with the cutting edge. The cutting edge is provided with a front positive angle, a back positive angle, a back negative angle and a front cutter face. The bottom of the front positive angle sags inward to form a chip breaker groove. A J shape is formed from the sharp end of the cutting edge to the bottom edge of the chip breaker groove. The front cutter face of the cutting edge is provided with a groove. A J-shaped chip breaker groove is formed in the bottom of the front positive angle of the cutting edge of the cutter. The cutting edge is fixedly arranged on one side of a cutter rod body of the cutter through a locating face and a suck screw. The front positive angle chip breaker groove of the J-shaped structure can provide good chip cutting control in the turning process of grooving, cutting-off, groove cutting and side face cutting. The groove formed in the front cutter face of a blade enables cut chip to be narrower and be coiled, so that the influence of the cut chip on the side wall of a processing groove is reduced to lowest. The chip breaker groove is applied to wide workpiece materials and processing conditions, and capable of processing satisfactory surface quality, and especially the bottom and the side wall of a groove.
Description
Technical field
The utility model relates to a kind of improved cutting edge, also relates to a kind of cutter of this cutting edge of application, belongs to the technical field of machining equipment.
Background technology
Cutting knife cutter is a kind of in machining, and kind is more, is used in a large number.But their Shortcomings parts: 1. chip-breaker at grooving, to cut off, cut in groove and side turning process that cutting controls be not fine; 2. smear metal is larger on the sidewall impact of institute's working groove; 3. cutting unification, cost is high, and efficiency is low; 4. blade tip height and rotating center are inconsistent.
Utility model content
The purpose of this utility model is to provide the cutter of a kind of improved cutting edge and this cutting edge of application, there is accurate grooving, cut off, cut groove, chamfering etc. multi-functional, with low cost, use high efficiency, solve the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of improved cutting edge, it is characterized in that, this cutting edge has positive rake angle, positive relief angle, negative relief angle and rake face, and the bottom of described positive rake angle caves inward and forms a chip-breaker, from the tip of described cutting edge, extremely forms " J " font in the base of described chip-breaker.
Further, on the rake face of described cutting edge, be provided with groove.
, it is characterized in that, the positive rake angle bottom of the cutting edge of this cutter has the chip-breaker of " J " font, and described cutting edge is fixedly mounted on knife bar main body one side of cutter by locating surface and sunk screw.
Further, described cutter has five cutting edges, and five cutting edges form equally distributed pentagon structure.
The useful technique effect that the utility model possesses is: the positive rake angle chip-breaker of " J " character form structure can be at grooving, cut off, cut groove and side, provides good smear metal to control in turning process; On blade rake face, designing groove can make smear metal narrow down, curling, so that smear metal reduces to minimum to the sidewall impact of institute's working groove, this chip-breaker is applicable to and workpiece material and processing conditions widely, can process bottom and the sidewall of satisfied surface quality, especially groove.Blade fixed placement near two lateral surfaces and guarantee that the high accurate performance in center solves blade can left cut bits, again can right cut bits, 5 effective cutting edges are used alternatingly, and have accurate grooving, to cut off, cut groove, chamfering etc. multi-functional.

The specific embodiment
By the description to embodiment below; to more contribute to public understanding the utility model; but the given specific embodiment of applicant can't be considered as to the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
As shown in Figures 1 to 4 improved cutting edge and application this cutting edge cutter, this cutting edge has positive rake angle 8, positive relief angle 5, negative relief angle 4 and rake face 6, the bottom of positive rake angle 8 caves inward and forms a chip-breaker 7, the tip of self-cutting sword forms " J " font to the base of chip-breaker, on the rake face at cutting middle part, is provided with groove.The positive rake angle of the cutting edge of this cutter has the chip-breaker of " J " font, cutting edge is fixedly mounted on knife bar main body 1 one sides of cutter by locating surface 2 and sunk screw 3, cutter has five cutting edges, and five cutting edges form equally distributed pentagon structure.The positive rake angle chip-breaker of " J " character form structure can be at grooving, cut off, cut groove and side, provides good smear metal to control in turning process; On the rake face 6 of blade, designing groove can make smear metal narrow down, curling, so that smear metal reduces to minimum to the sidewall impact of institute's working groove, this chip-breaker is applicable to and workpiece material and processing conditions widely, can process satisfied surface quality, especially the bottom of groove and sidewall.Blade fixed placement near two lateral surfaces and guarantee that the high accurate performance in center solves blade can left cut bits, again can right cut bits, 5 effective cutting edges are used alternatingly, and have accurate grooving, to cut off, cut groove, chamfering etc. multi-functional.
Certainly; the utility model can also have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
