Abstract

The utility model discloses a convex triangular chute milling cutter blade which relates to a triangular milling cutter blade and is used for solving the problems that the cutting depth needs to be enlarged traditionally for efficient milling and the milling cutter blades of different types are bad in generality. The cross section of the milling cutter blade is triangular; the appearance of the milling cutter blade takes the shape of a three-edge table; a groove which is in accordance with the three-edge table-shaped milling cutter blade in the aspect of appearance is arranged on the large end face of the three-edge table-shaped milling cutter blade; the wall surface of the groove is the front cutter face of the milling cutter blade; a convex prismatic table which is in accordance with the bottom end face of the groove in the aspect of shape is arranged in the middle of the bottom end face of the groove; the area of the table end face of the convex prismatic table is less than the area of the bottom end face of the groove; the side surface of the convex prismatic is an inclined surface; a chip breaker groove, the cross section of which is V-shaped, is formed between the side surface of the convex prismatic table and the front cutter face; a fastening bolt hole is machined at the center of the convex prismatic table; and an arc transition edge is machined at each corner part at the edge of the large end face of the three-edge table-shaped milling cutter blade. The convex triangular chute milling cutter blade is used for milling workpieces.

Description

Protruding triangle skewed slot cutter blade

Technical field

The utility model relates to a kind of triangular-shaped blades sheet, is specifically related to a kind of protruding triangle skewed slot cutter blade, belongs to the Machining Technology field.

Background technology

The employed cutter blade of mechanical processing industry owing to the restriction of its structure, can only use in limited scope at present.Most of cutter blade will be realized high-efficient milling, mainly is the high efficiency that reaches material removing rate through the increase cutting depth, and this method tends to accelerate the wearing and tearing of cutter blade.Simultaneously, conventional cutter blade is after surpassing own range of application, and its cutting ability will be had a greatly reduced quality, and conventional cutter blade does not possess good universal performance.For example: the circular knife milling cutter is for overhanging and/or the profile milling of steady working condition is processed with good effect for a short time, but triangular blade will produce bigger vibration in this case.

The utility model content

The purpose of the utility model provides a kind of protruding triangle skewed slot cutter blade, realizes that to solve tradition high-efficient milling need increase the problem of cutting depth and dissimilar cutter blade versatility differences.

The utility model is to address the above problem the technical scheme of taking to be: protruding triangle skewed slot cutter blade; The cross section of cutter blade is a triangle; The profile of cutter blade is three terrace with edge shapes, and the large end face of three terrace with edge shape cutter blades is provided with and the corresponding to groove of three terrace with edge shape cutter blade profiles, and the wall of groove is the rake face of cutter blade; The middle part of the bottom face of groove is provided with and the corresponding to protruding terrace with edge of this bottom face shape; The you face area of protruding terrace with edge is less than the bottom face area of groove, and the side of protruding terrace with edge is the inclined-plane, and forming cross section between the side of protruding terrace with edge and the rake face is the chip-breaker of V-type; The center of protruding terrace with edge is processed with the trip bolt hole, and each bight at the large end face edge of three terrace with edge shape cutter blades is processed with an arc transition sword.

The beneficial effect of the utility model is: the protruding triangle skewed slot cutter blade of the utility model versatility in high-efficient milling processing is good; Cutter life is long; And; Need not to increase cutting depth and can obtain the metal resection rate higher than common process, the cutter blade of the utility model is in the high efficiency Milling Process, and maximum feeding reaches 1.5-3mm/Z.The arc transition sword of the utility model has effectively reduced the roughness on workpiece to be machined surface, has slowed down tool wear, effectively raises cutter life more.Simultaneously, the zone that each of cutter blade participated in cut all can constitute stable triangle, effectively raises the intensity and the impact resistance of cutter; The cross section of cutter blade is the chip-breaker of V-type, can carry out effectively curling to smear metal, reaches good chip breaking effect.

Description of drawings

Fig. 1 is the front view of the utility model, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the vertical view of Fig. 1, and Fig. 4 is the rearview of Fig. 1, and Fig. 5 is the stereogram of the utility model.

The specific embodiment

The specific embodiment one: combine Fig. 1 to Fig. 5 to explain; The protruding triangle skewed slot cutter blade of this embodiment; The cross section of cutter blade 1 is a triangle; The profile of cutter blade 1 is three terrace with edge shapes, and the large end face of three terrace with edge shape cutter blades is provided with and the corresponding to groove of three terrace with edge shape cutter blade profiles, and the wall of groove is the rake face 3 of cutter blade 1; The middle part of the bottom face of groove is provided with and the corresponding to protruding terrace with edge 2 of this bottom face shape; The you face area of protruding terrace with edge 2 is less than the bottom face area of groove, and the side of protruding terrace with edge 2 is the inclined-plane, and forming cross section between the side of protruding terrace with edge 2 and the rake face 3 is the chip-breaker 4 of V-type; The center of protruding terrace with edge 2 is processed with trip bolt hole 5 (whole cutter blade is fixed on the lathe tool knife bar through trip bolt), and each bight at the large end face edge of three terrace with edge shape cutter blades is processed with an arc transition sword 6.

The specific embodiment two: combine Fig. 2 and Fig. 4 explanation, the outline place of the small end face of the three terrace with edge shape cutter blades of this embodiment is processed with notch 7.So design effectively reduces the blade thermal deformation that cutter blade Yin Gaowen causes, has increased area of dissipation simultaneously, has reduced the contact area of blade and knife bar, plays good thermolysis.Other is identical with the specific embodiment one.

The specific embodiment three: combine this embodiment of Fig. 2, the relief angle α of the back knife face of the cutter blade 1 of this embodiment is 7 °, and the anterior angle β of the rake face 3 of cutter blade 1 is 7 °.Plastic deformation when so design, the existence of anterior angle can reduce rake face extruding cutting lay reduces the smear metal frictional resistance of rake face of flowing through, thereby has reduced cutting force, heat in metal cutting and power; Relief angle can effectively prevent the friction of back knife face and workpiece machined surface, has both improved the machining accuracy of workpiece, also can effectively prevent the wearing and tearing of back knife face simultaneously, improves cutter life.Other is identical with the specific embodiment one or two.
