Abstract
This utility model relates to an inverted external R formed milling cutter for processing a long arm with inverted external R parts. A cutter head of the milling cutter consists of six teeth; a main cutting edge of each teeth and a level form an R-shaped surface which consists of the main cutting edge, a side cutting edge and an exclusive cutting edge; the main cutting edge is an R-shaped surface; the side cutting edge and the main cutting edge form sixty degrees in horizontal direction; the exclusive cutting edge and the main cutting edge form fifteen degrees in horizontal direction; an angle between the teeth is sixty degrees. The main cutting edge is an R-shaped surface from R3 to R10. The main cutting edge is designed into R with different sizes for moulding processing of different external R parts; field processing has good effect and achieves requirement of part process quality completely. With an interior R cutter for side edge processing, process time is reduced and process quality is improved, in particular when processing parts of the long arm and part inverted R with a large curvature change, the process time is reduced from the prior four hours to twenty minutes, thereby improving work efficiency.
Description
Technical field:
The utility model relates to a kind of long-armed profile milling cutter that has down the used outer R of outer R part processing that is used to process.
Background technology:
Originally the part of the long-armed type of processing more than one meter outside during R, cylindrical bar milling cutter processing R place is adopted at the R position, the mode that tool path pattern adopts row to cut, and shortcoming is a long processing time, be easy to generate jump with abutted surface behind the outer R, processing rear surface quality does not reach requirement.Also must polish by hand.If adopt manual grinding fully, for the R that falls of the length of such length, it is very time-consuming to polish, and the surplus of polishing is big, manual grinding cambered surface instability.
Summary of the invention: the purpose of this utility model provides the profile milling cutter that abutted surface behind a kind of outer R of part of the long-armed type more than a meter does not produce the outer R of jump.Technical solution of the present utility model is, the cutter head of milling cutter is made up of six teeth, the main cutting edge of each tooth is horizontal by R type shape face, R type shape face is cut sword by main cutting edge, front cutting edge and row and is formed, main cutting edge is R type shape face, front cutting edge becomes to be 60 degree angles with the main cutting edge horizontal direction, and row cuts sword and becomes to be 15 degree angles with the main cutting edge horizontal direction, and the between cog angle is 60 degree.Main cutting edge is the R type shape face of R3～R10.The utility model is designed to the R of different size with main cutting edge, helps the processing and forming of different outer R parts.On-the-spot processing effect is good.Reach the part processing quality requirement fully.Utilize interior R cutter of the present utility model to carry out side edge processing, promptly shortened process time and improved crudy again.Particularly when long-armed, the curvature of processing changed big partly part of outer R, shortened to 20 minute from original 4 hours process time, and effect is remarkable, and is practical, improved the processing operating efficiency.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a main cutting edge schematic diagram of the present utility model.
The specific embodiment
The cutter head of milling cutter is made up of six teeth 4, the main cutting edge 3 of each tooth is horizontal by R type shape face 6, R type shape face 6 is cut sword 1 by main cutting edge 3, front cutting edge 2 and row and is formed, main cutting edge 3 is R type shape face, front cutting edge 2 becomes to be 60 degree angles with main cutting edge 3 horizontal directions, row cuts sword 1 and becomes to be 15 degree angles with main cutting edge 3 horizontal directions, and 4 angles of each tooth are 60 degree.
Profile milling cutter is divided into staight shank type and taper shank type, and the material of cutter is W18C
r4V, row cut sword 1 and become 15 degree angles with the horizontal direction of main cutting edge 3.Front cutting edge 2 is 60 degree angles with main cutting edge 3.Main cutting edge 3 can be in the R3-R10 scope, falls the demand of different R to adapt to different parts.Profile milling cutter is six tooth milling cutters, and the angle that each tooth is 4 is 60 degree.The cutter that is designed to different clamping size styles like this helps the equipment processing of different clamping cutters, and on-the-spot processing effect is good, reaches the part processing quality requirement fully.
Claims (2)
1. profile milling cutter of outer R, it is characterized in that, the cutter head of milling cutter is made up of six teeth, the main cutting edge of each tooth becomes to be R type shape face with horizontal plane, R type shape face is cut sword by main cutting edge, front cutting edge and row and is formed, and main cutting edge is R type shape face, and front cutting edge becomes to be 60 degree angles with the main cutting edge horizontal direction, row cuts sword and becomes to be 15 degree angles with the main cutting edge horizontal direction, and the between cog angle is 60 degree.
2. the profile milling cutter of outer R according to claim 1 is characterized in that, main cutting edge is the R type shape face of R3～R10.
