Description
Technical field
The utility model relates to the lathe tool technical field of metal cutting process, is specifically related to a kind of turning insert with point of a knife reinforced structure.
Background technology
In metal cutting process, because the difference of machining condition and workpiece material can produce polytype chip, these chips need to discharge in time, otherwise can affect the carrying out of machining.Long large-scale chip easily injures operator, is unfavorable for safety in production, and can reduce the precision of workpiece and increase the roughness of surface of the work, reduces the cutting quality of workpiece, therefore should avoid the generation of large-scale chip in working angles.Cutter arranges chip-breaker to carry out curling to chip and to fracture be a kind of comparatively general method, the shape of chip-breaker is for for the curling of chip and the important impact that fractures.The chipbreaker structures of existing blade is for the curling of large-scale chip and the limited efficiency that fractures, and the Chip Shape after process is still not ideal.In addition, the damaged ability of the point of a knife anti-fatigue performance of existing blade and shock resistance is more weak, makes the service life of blade shorter.
Utility model content
The purpose of this utility model is to provide a kind of turning insert with point of a knife reinforced structure, it is better with the effect that fractures to the curling of the large-scale chip produced in working angles, can good bits shape be formed, anti-fatigue performance and the damaged ability of shock resistance of point of a knife can be improved simultaneously.
The technical solution of the utility model is for achieving the above object: a kind of turning insert with point of a knife reinforced structure, comprising a cross section is foursquare cutter hub, on cutter hub has, lower two end faces and four sides, the center of cutter hub is provided with installing hole, the upper surface of cutter hub is provided with chip-breaker, chip-breaker is that trapezoidal groove edge surrounds by four vertical sections, four described grooves are along corresponding with four sides of cutter hub respectively, groove is less than the width of bottom surface along the width of end face, connected by cambered surface transition between the lateral surface on two adjacent groove edges, the medial surface on described groove edge by the end face on groove edge to chip-breaker inner inclination, the lateral surface on groove edge by the end face on groove edge to chip-breaker outer inclination, groove connects along the bottom of lateral surface and the side of cutter hub, described mounting hole site is in the center of chip-breaker, two adjacent grooves are provided with boss along the intersection of end face, boss side surfaces corresponds to the part of chip-breaker inside and the either flush on groove edge, the side of boss remainder is arcwall face, this arcwall face and described adjacent two grooves are connected smoothly along the cambered surface between lateral surface.
Beneficial effect: chipbreaker structures of the present utility model is based on the design of mosquito Oral strueture, and its lateral cross section is trapezoidal shape, for the curling of large-scale chip and the better effects if that fractures.Chip-breaker groove is provided with boss structure along the intersection of end face; it can strengthen antifatigue and the shock resistance of point of a knife, serves effective compartmentation to major-minor cutting edge simultaneously, by most of chip guiding main cutting edge direction; protect front cutting edge, be comparatively applicable to cutting difficult-to-machine material.Boss side surfaces is designed to arcwall face structure, and this arcwall face and adjacent two grooves are connected smoothly along the cambered surface between lateral surface, so advantageously leads in chip to main cutting edge direction, protection front cutting edge.

Fig. 1 structural representation of the present utility model.
Be labeled as in figure: 1, cutter hub, 11, side 2, installing hole, 3, chip-breaker, 31, groove edge, 4, boss.
Detailed description of the invention
As shown in Figure 1, a kind of turning insert with point of a knife reinforced structure, comprising a cross section is foursquare cutter hub 1, cutter hub 1 overall structure is cuboid, on cutter hub 1 has, lower two end faces and four sides 11, the center of cutter hub 1 is provided with installing hole 2, installing hole 2 is for being installed to handle of a knife by blade, the upper surface of cutter hub 1 is provided with chip-breaker 3, chip-breaker 3 is that trapezoidal groove surrounds along 31 by four vertical sections, four described grooves are corresponding with four sides 11 of cutter hub 1 respectively along 31, groove is less than the width of bottom surface along the width of 31 end faces, connected by cambered surface transition between the lateral surface of two adjacent grooves along 31, the design of this cambered surface can strengthen antifatigue and the shock resistance of point of a knife further, the medial surface of described groove along 31 by the end face of groove along 31 to chip-breaker 3 inner inclination, the lateral surface of groove along 31 by the end face of groove along 31 to chip-breaker 3 outer inclination, groove connects along the bottom of 31 lateral surfaces and the side 11 of cutter hub 1, described installing hole 2 is positioned at the center of chip-breaker 3, two adjacent grooves are provided with boss 4 along the intersection of 31 end faces, part and groove that boss 4 side the corresponds to chip-breaker 3 inside either flush along 31, the side of boss 4 remainder is arcwall face, this arcwall face and described adjacent two grooves are connected smoothly along the cambered surface between 31 lateral surfaces.
Described boss 4 entirety can also be set to the shape such as circle or triangle, in order to strengthen point of a knife structure further, boss 4 can also use Laser Processing some micron order micro-structural and grooves, the cutting selfreparing realizing strengthening point of a knife structure can be coordinated with the reparation Particle Phase in cutting fluid like this.
The cross section of described cutter hub 1 entirety is of a size of 16mm × 16mm, and chip-breaker 3 bottom land is foursquare is designed and sized to 8mm × 8mm.Groove is 1.5mm along the width of 31 end faces, and groove is 35 ° along the angle of inclination of 31 medial surfaces, and the angle of inclination of lateral surface is 35 ° ~ 45 °.Groove is 1.5mm along the width of 31 end faces, and the angle of inclination of medial surface is 35 °, further can improve the effect of chip-breaker like this.
Connected by arc surface transition between two sides 11 that described cutter hub 1 is adjacent.Circular arc cuts transitional edges can make cutting more smooth, steadily, and has certain for sharp characteristic, improves the shock resistance breakage ability of point of a knife simultaneously, enhances cutting zone anti-fatigue performance.
Described groove is connected along the arc surface transition being 1.5mm by a radius between the bottom and the side 11 of cutter hub 1 of 31 lateral surfaces, the design of this arc surface can reduce in working angles, workpiece, to the impact stress of insert tip, avoids the generation of tipping situation in working angles.
Turning insert of the present utility model has four and cuts stations, after cutting station wearing and tearing, can be transformed on other stations of blade, can reduce like this in cutting process due to workpiece resetting error that frequent tool changing brings when one.
