Technical field

The utility model relates to technical fields of mechanical processing, and in particular to a kind of for processing the vertical milling of cylindrical workpiece Knife.

Background technique

Cylindrical shape and ring-like key is very long in machining sees, cylindrical shape such as cellular phone power supplies key, laptop Key, the technique of conventional machining are processed with end mill(ing) cutter, and there is long processing times for such technique, and processing dimension is unstable, adds Knife is needed to mend when work tune machine, operation is more complicated, vibration knife is in addition easy in processing, the surface quality of processing is poor, influences beauty.

Utility model content

The purpose of this utility model is that aiming at the shortcomings in the prior art, and provide a kind of for processing cylindrical workpiece Slotting cutter, milling can be inserted directly to process cylindrical workpiece, have high in machining efficiency and operate simpler convenient excellent Point.

The purpose of this utility model is achieved through the following technical solutions:

It is a kind of for processing the slotting cutter of cylindrical workpiece, including knife handle, one end of knife handle is equipped with an inclined surface, inclined surface Connect blade；Slotting cutter is additionally provided with the spiral helicine chip space that blade is extended to from inclined surface, and chip space has two, relatively sets The two sides of blade are placed in, so that blade is divided into the first cutting edge and the second cutting edge；First cutting edge and the second cutting Sword is equipped with the end sword forward extended out.

Further, all sword cross sections of blade are positive polygonized structure, and the angle between adjacent two surface of Zhou Ren is α, then 9 °≤α≤23 °.

Further, end sword is equipped with the first relief angle and the second relief angle, and the angle of the first relief angle is β 1, the angle of the second relief angle For β 2, wherein 2≤30 ° of 5≤β, 1≤15,10 °≤β；The width of first relief angle is 0.16mm.

Further, 1=7 ° of the angle beta of the first relief angle, 2=15 ° of angle beta of second relief angle.

Further, knife handle is cylindrical body, and knife handle connects blade by inclined surface, and transition is equipped between inclined surface and blade The shaft shoulder.

Further, the cutting edge of blade is coated with ALTiN coating.

Further, the inclination angle of inclined surface is 30 °.

The utility model has the beneficial effects that

The utility model it is a kind of for processing the slotting cutter of cylindrical workpiece, chip space has two, be oppositely disposed in The two sides of blade, so that blade is divided into the first cutting edge and the second cutting edge；First cutting edge and the second cutting edge are equal Equipped with the end sword forward extended out, slotting cutter by using this structure, can be by directly inserting come when processing cylindrical workpiece The mode of milling is processed, and enormously simplifies the processing process of existing cylindrical workpiece.

Meanwhile the Zhou Ren of positive gengon structure this be used to process when slotting cutter of cylindrical workpiece is put the first edge on a knife or a pair of scissors play it is auxiliary Help the effect of cutting, it is therefore prevented that this " the long blade type slotting cutter of class " structure of the first cutting edge and the second cutting edge forward extended out exists The case where vibration and cutter easily occurred when feeding since amount of deflection is larger is lost generation.

Detailed description of the invention

Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not constituted to the utility model Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached Figure obtains other attached drawings.

Specific embodiment

The utility model is further described with the following Examples.

The utility model it is a kind of for processing the slotting cutter of cylindrical workpiece, as depicted in figs. 1 and 2, including knife handle 1, One end of knife handle 1 is equipped with the inclined surface 2 that an inclination angle is 30 °, and inclined surface 2 connects blade, and the cross section of all swords 5 of blade is positive Gengon structure, the angle between adjacent two surface of all swords 5 is α, α=15 °.Slotting cutter is additionally provided with from cutter hub and extends to blade Spiral helicine chip space, chip space has two, is oppositely disposed in the two sides of blade, to be divided into first to cut blade Cut sword 31 and the second cutting edge 32；First cutting edge 31 and the second cutting edge 32 are equipped with the end sword forward extended out, and end sword is equipped with First relief angle 41 and the second relief angle 42,1=7 ° of angle beta of end the first relief angle of sword, 2=15 ° of angle beta of end the second relief angle of sword, end The width of the first relief angle of sword 41 is 0.16mm.First cutting edge 31 and the second cutting edge 32 are equipped with the end sword forward extended out, add Working hour directly passes through the end sword forward extended out and puts the first edge on a knife or a pair of scissors, and all swords 5 of regular polygon type also function to the effect of assisted machining, this Sample can be high in machining efficiency directly to process the workpiece of cylinder type by way of inserting milling, easy to operate.The structure of all swords 5 Also the first cutting edge 31 forward extended out and this " the long blade type slotting cutter of the class " structure of the second cutting edge 32 can be prevented in feeding The case where vibration and cutter easily occurred since amount of deflection is larger is lost generation, further improves machining accuracy.

Wherein, knife handle 1 is cylindrical body, and the transition shaft shoulder 6 is equipped between knife handle 1 and blade, and 6 one side of the transition shaft shoulder makes this Slotting cutter for processing cylindrical workpiece is easily worked, and on the other hand also increases its whole rigidity.The cutting edge of blade applies It is covered with ALTiN coating, considerably increases the wearability of cutter, to increase cutting-tool's used life.All 5 assisted machinings of sword make The operating of this slotting cutter is more stable, and the polarization in process is small, and cooperation is equipped with the blade of ALTiN coating, so that processing The cylindrical workpiece come has lesser surface roughness.
