The specific embodiment
Referring to Fig. 1～Fig. 8, the utility model embodiment bearing ring beveler folder indexable insert tip, throw away tip 1 need not sharpening on emery wheel, directly installs and just can use.The design feature of blade 1 comprises and is processed with four cutting edges 11 on the blade 1; Have chip area H on the cutting edge 11; Each cutting edge 11 all is made up of with knuckle R cutting edge inclined-plane 12, and blade 1 side is interlocked by four cutting edge inclined-planes 12 and four common inclined-planes 13 and constitutes, and cutting edge inclined-plane 12 and common inclined-plane 13 all are processed with the relief angle of certain angle (before above Fig. 1 being; It is the position of part to be processed; After Fig. 1 below was, relief angle was meant that the rear portion on cutting edge inclined-plane 12 and common inclined-plane 13 is all inwardly in other words to blade 1 center line G inclination certain angle) relief angle equals the included angle A of common inclined-plane 13 and blade 1 center line G), the best special case of relief angle is 6 °; Relief angle on the ramp angle J of blade bearing 4 and the blade 1 is formed total relief angle of cutter; The best special case of ramp angle J is 5 °, and promptly the best special case of total relief angle is 11 °, and total relief angle design of cutter makes cutting edge 11 slightly tilt to part to be processed; When improving working (machining) efficiency, can guarantee that again service life is longer, the appropriate scope of total relief angle of cutter is 8 °～12 °.Cutting edge 11 middle parts are equipped with knuckle R; Knuckle R cooperates with the chamfering of bearing ring 8; The two ends of cutting edge 11 are respectively arranged with first included angle B and the second angle C; The best special case of first included angle B and the second angle C is respectively 30 ° and 15 °, and the best special case of the width D of blade 1 (referring to the ultimate range up and down of Fig. 2) is 16 millimeters, and cutting edge 11 does not wait at the projector distance on corresponding two common inclined-planes 13; The first wherein long projector distance E is 6 millimeters, and the second short projector distance F is 4 millimeters.The design that first included angle B and the second angle C do not wait and the projector distance of cutting edge 11 on corresponding two common inclined-planes 13 do not wait makes the chip removal of chip area H have specific direction, helps smooth chip removal.Four identical cutting edges 11 with respect to blade 1 center line G be evenly distributed on blade 1 four angles (any cutting edge 11 around blade 1 center line G respectively half-twist, 180 °, 270 ° promptly overlaps fully with other three cutting edges 11 respectively, promptly four cutting edges 11 are symmetrical with respect to blade 1 center line G rotation).
The utility model is whole to be made up of lathe tool blade 1, push type broach device 2, housing pin 3, blade bearing 4, blade bearing connection screw 5, knife bar 6.Blade bearing 4 usefulness blade bearings connect screw 5 and are fixed on the knife bar 6, blade 1 blade bearing 4 and fixing through push type broach device 2 of packing into.
At first connecting screw 5 to blade bearing 4 usefulness blade bearings during use is connected on the knife bar 6; Then correctly pack blade 1 into and install push type broach device 2 again in the blade bearing 4 and tighten housing pin 3 at last; Whole like this connect lathe tool finishes, and next is installed to lathe tool on the lathe cutter saddle 7, debugged the position of lathe and lathe tool; Lathe tool is installed and just have been accomplished so first, chamfering that then just can machining bearing lasso 8.When 11 wearing and tearing of blade cut sword or with removing together with knife bar after blunt, as long as come loose housing pin 3,, need not to debug again and can drop into cutting turning 90 degrees in blade 1 horizontal plane, can save operating personnel's time greatly.When four cutting edges 11 all wear and tear or during with blunt can not the use; The available blade 1 of pulling down; Directly install to behind the well back blade 1 of four of reconditioning blade 1 cutting edges 11 on the blade finishing machine, reconditioning and tighten housing pin 3 on the blade bearing 4, need not to debug again and can drop into cutting fast; A slice blade can repeat repeatedly reconditioning like this, greatly reduces the consuming cost of cutter.
