Insert of the prior art as the patent No. be " 201110426614.2 " " a kind of milling cutter " it be exactly adopt carbide chip to be embedded in structure on bit body, but because this cutter head end face is flat, carbide chip concordant with end face.And carbide chip adopts common planar structure or negative rake structure, although intensity is little compared with high shear action, need to rely on powerful main shaft to export, so energy consumption is serious, and easily produce built-up edge, make cutting region high temperature, reduce the surface accuracy being cut part.
Summary of the invention
For above-mentioned situation, the utility model provides a kind of inserted milling cutter head, adopt the design of positive rake angle and special chip discharging structure, in guarantee chip removal usually, reduce the requirement to main shaft power, cut the heat produced little, and surface of the work precision is high, simultaneously also relatively less for the wearing and tearing of lathe.
To achieve these goals, the technical solution of the utility model is as follows:
Inserted milling cutter head, comprise cutter head, carbide chip and securing member, cutter head sidewall annular is uniformly distributed some cutter grooves, cutter groove side is provided with securing member connecting hole, carbide chip is provided with fixing hole, securing member is fastenedly connected end and stretches among securing member connecting hole through carbide chip, described carbide chip adopts positive rake angle structure, the positive rake angle of carbide chip is 33 ~ 35 degree, hemispheric interior concave spherical surface is had in the middle part of cutter head end face, enclose inclined-plane by one between interior concave spherical surface and cutter head outer to couple together, a channel of chip removal is equipped with between interior concave spherical surface and each cutter groove.
As preferred embodiment, described channel of chip removal is around cutter head axle center Spiral distribution.
As preferred embodiment, the positive rake angle of described carbide chip is 34 degree.
When the design of interior concave spherical surface is the carbide chip cutting in order to make have employed positive rake angle, a small amount of cutting swarf inwardly splashed of generation enters Internal Spherical Surface instead of splashes on the end face of cutter head, thus enters among cutter groove along channel of chip removal, and then discharges cutter head.The shape that channel of chip removal is designed to spiral considers that cutting swarf is subject to gathering the centrifugal action of power and cutter head rotation among interior concave spherical surface, so in order to prevent cutting swarf from blocking, is designed to the shape be consistent with centrifugal force track.The design on inclined-plane can will reserve a larger space between interior concave spherical surface and end face, thus when preventing cutter head from cutting, between interior concave spherical surface and end face, air is less, makes crumb loading adhesion.
The design of positive rake angle can make main cutting force decline, and also reduces radial-thrust force and feed drag simultaneously.Positive rake angle can make cutter sharper, cuts more brisk.The intensity of cutter itself may be caused also to decline because positive rake angle is too large, so the positive rake angle of carbide chip fixes on 33 ~ 35 degree.
The utility model has the advantages that: adopt the design of positive rake angle and special chip discharging structure, in guarantee chip removal usually, reduce the requirement to main shaft power, cut the heat produced little, and surface of the work precision is high, simultaneously also relatively less for the wearing and tearing of lathe.
