Working method of the present utility model and process are as follows:
With the hilted broadsword hair style one-shot forming chamfering knife tool among the embodiment one is the example explanation.
The course of work of the present utility model can be divided into: go into cutter, via hole, portal and go out cutter.
Go into cutter: as Fig. 7, the other end relative with advancing nose end 3 on knife bar 1 is the cutter bare terminal end, use drilling machine that the cutter bare terminal end on the knife bar 1 is fixedly clamped, open drilling machine, cutter is turned clockwise, and on cutter, apply certain axial force, make in the hole of cutter on workpiece motion or make workpiece to be machined to tool motion, since this cutter advance the nose end 3 end guide head 8 that is with hole, enter nose end guide head 8 surface and be smooth arc surface, can enter in the aperture smoothly.When the advancing nose end 3 and touch the outer end of workpiece hole of cutter, because cutter rotates, 5 moments of the first chamfering cutting edge just can be removed the outer end burr in hole, and shape chamfering at 45.
Via hole: as Fig. 8, continue into cutter, be provided with the end shrinkage joint 7 that is with hole owing to advance nose end 3, advancing nose end shrinkage joint 7 shrinks under the convergent force in hole, shrinkage joint opening angle 9 diminishes gradually at this moment, make knife and fork 12 shrink automatically and also pass through hole smoothly, and utilize hole wall hair defect cutting edge 4 to remove the hole wall burr fast.
Portal: as Fig. 9, after hole wall hair defect cutting edge 4 has been removed the hole wall burr, hole wall hair defect cutting edge 4, the first chamfering cutting edge 5 and the second chamfering cutting edge 6 stretch out from hole, finish and portal, simultaneously, the other end of the second chamfering cutting edge, 6 contact holes, the i.e. the inner in hole, moment this moment is removed the hair defect of the inner in hole, and forms 33 ° chamfering.
Go out cutter: as Figure 10, make cutter or workpiece towards with go into the motion of the opposite direction of cutter, make the second chamfering cutting edge 6 other end of contact hole for the second time, i.e. the inner in hole, moment this moment is thoroughly removed the hair defect of the inner in hole, and forms 33 ° chamfering.Continue to make cutter or workpiece towards the direction motion opposite, cutter is proposed in the hole, make the process that this process is gone into cutter, via hole equally and portalled with going into cutter.So only need a clamping, just can finish the cutting and the repairing of hole wall hair defect of twice bilateral chamfering and remove.
Remove if only need carry out the cutting and the repairing of hole wall hair defect of one-sided chamfering, can save the process of portalling, the process of only going into cutter, via hole and going out cutter gets final product.
This cutter is in use behind the blunt, also only need once to grind and simultaneously the second chamfering cutting edge 6, hole wall cutting edge 4 and the first chamfering cutting edge 5 to be become sharp again, still can normally use after the grinding again through 4 times, improve the service life of cutter greatly, come convenience again for operation and maintenance.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection all is documented in claims.
