Abstract
The utility model discloses a drum-shaped milling cutter, which comprises a cutter rod, a cylindrical cutter body and a drum-shaped cutter head. The cutter rod is connected with the cylindrical cutter body through welding, the cylindrical cutter body is integrated with the drum-shaped cutter head, the center of the bottom surface of the drum-shaped cutter head is provided with an arc-shaped vacancy avoiding slot, a blade is arranged on the middle lower part of the cylindrical cutter body and the side face of the cutter head, the middle arc radius of the side face of the drum-shaped cutter head is 1-2mm, the lower arc radius of the side face of the drum-shaped cutter head is 6-7mm, and the arc radius of the part of the drum-shaped cutter head connected with the bottom surface is 4.5-5.5mm. The drum-shaped milling cutter has good finish on the processing surface, the bevel surface can be formed in one step, and the processing efficiency is high.
Description
Technical field
The utility model relates to the cutter field, particularly a kind of cydariform milling cutter that aluminum component is processed.
Background technology
Along with going deep into gradually of low-carbon environment-friendly consciousness,, cut down the consumption of energy for weight reduction; Improve heat dispersion; The shell of a lot of devices all can be designed to aluminum component in Machine Design, adds man-hour at the inboard variable inclination face to aluminum component, needs to use the cydariform milling cutter to process.Existing cydariform milling cutter generally is a milling cutter that the cross section is a cydariform, and blade is arranged on the side, and the bottom surface is the plane, is adding man-hour, and chip removal has some setbacks, and easily workpiece is scratched.
Summary of the invention
The purpose of the utility model is to have some setbacks to the chip removal that the existing cydariform milling cutter described in the background technology exists, and the problem that easily workpiece is scratched provides a kind of cydariform milling cutter that can solve foregoing problems.
The technical scheme of goal of the invention that can realize the utility model is following:
A kind of cydariform milling cutter, it comprises knife bar, cylindrical blade and cydariform cutter head, knife bar and cylindrical blade are welded to connect; Cylindrical blade is connected with the first body of drum knife; The bottom center of cydariform cutter head is provided with the avoiding hollow groove of circular arc, and blade is arranged at the middle and lower part of cylindrical blade and the side of cutter head, and middle part, the side arc radius of cydariform cutter head is 1-2mm; The arc radius of bottom is 6-7mm, and the position arc radius that the cydariform cutter head is connected with the bottom surface is 4.5-5.5mm.
The radius of the arc surface of described avoiding hollow groove is 14-16mm.
Described avoiding hollow groove is 8.0-8.5mm at the diameter of lonely star head base surface.
The beneficial effect of the utility model is because the bottom surface of the cydariform milling cutter of the utility model is provided with the avoiding hollow groove of circular arc; The inboard variable inclination face of aluminum component is being added man-hour; Avoiding hollow groove can prevent on the one hand contacting of milling cutter bottom surface and non-Working position; Can make things convenient for chip removal on the other hand, avoid chip that workpiece is scratched, guarantee the surface smoothness of workpiece.
Description of drawings
Fig. 1 is the sketch map of the utility model;
Among the figure, 1 is knife bar, and 2 is cylindrical blade, and 3 is the cydariform cutter head, and 4 is avoiding hollow groove.
The specific embodiment
With reference to a kind of cydariform milling cutter shown in Figure 1; It comprises knife bar 1, cylindrical blade 2 and cydariform cutter head 3; Knife bar 1 is welded to connect with cylindrical blade 2, and cylindrical blade 2 is connected with cydariform cutter head 3 one, and the bottom center of cydariform cutter head 3 is provided with the avoiding hollow groove 4 of circular arc; Blade is arranged at the middle and lower part of cylindrical blade 2 and the side of cutter head; Middle part, the side arc radius of cydariform cutter head 3 is 1-2mm, and the arc radius of bottom is 6-7mm, and the position arc radius that cydariform cutter head 3 is connected with the bottom surface is 4.5-5.5mm; The radius of the arc surface of described avoiding hollow groove 4 is 14-16mm.; Described avoiding hollow groove 4 is 8.0-8.5mm at the diameter of lonely star head base surface.
