Patent ID: 6845647

Claim:
A heat sink processing method including the steps of: a) providing a working machine with a feeding mechanism in a working zone; b) driving an elastically extending and contracting knife set and a stopping and pushing mechanism having a fin fixing rod and a pushing edge utilizing a power arm of the working machine; c) fixing a material block on said feeding mechanism which progresses a predetermined distance; d) cutting said material block to create a fin utilizing the elastically extending and contracting knife set; e) advancing the material block a predetermined distance utilizing the stopping and pushing mechanism; and f) repeating the cutting step d) and the advancing step e) a predetermined number of times to produce a plurality of fins in a heat sinking area, wherein in the advancing step e) interspaces in the feeding material are determined by a dial provided on a follower axle on a power arm of said working machine and by rotating a bolt of the feeding mechanism a fixed distance to a predetermined position by utilizing a mechanically linked-up differential.
