Abstract

The present invention provides a cutting method to cut the substrate (1) of the heat sink materials (M) rapidly to the product of cooling fins (m) by the specified length. The stopper (6) moves from the front of the cutting position (CP) of the heat sink materials across the datum of the cutting position (CP) and stops on the root of the heat sink fins (2a) of the front group of heat sink fins (3) to define the standard length Α of the front heat sink fins on the substrate (1). The propeller (7) drives the heat sink materials (M) to make the stopper (6) stop on the root of the front heat sink fins (2a). First, make the stopper (6) locate at the datum and stop on the root of the heat sink fins (2a) of the front group of heat sink fins (3) by the propeller (7), and then cut off the front heat sink fins (2a). After that, move the heat sink materials by the defined length and cut off the back heat sink fins (2b). Repeat the above procedures.

457152 1. A fixed-length cutting method for a heat-dissipating material, a plurality of heat-radiating fin groups that protrude a predetermined number of predetermined number of heat-radiating fins on a strip-shaped substrate portion in the lengthwise direction of the substrate portion are formed at fixed intervals in the lengthwise direction of the substrate portion The base plate portion of the bulk material is cut into each heat sink group at a cutting position by a fixed blade. The characteristic is that a stopper is provided, and the front side of the heat transfer material in the cutting position is over the cutting position. The reference position is blocked at the root of the front fins of the front fin group to regulate the reference length of the front fin side of the base plate; and the pusher, which can stop the stopper at the root of the front fins and pass the heat sink from it. The rear end is pushed to the conveying direction; firstly, the stopper is positioned at the reference position, and the stopper is blocked by the front end of the front fin group of the front fin group, and then the front fin side is cut off. Transfer the heat sink to a predetermined length and cut off the rear heat sink side. Repeat the above process. A fixed-length cut of a heat-dissipating material is arranged on a strip-shaped substrate portion. A fixed distance between the heat-radiating fins in the lengthwise direction of the substrate portion will protrude a predetermined number of heat-radiating fin groups at a fixed interval in the lengthwise direction of the substrate portion. The substrate portion of the heat sink is cut into each heat sink group by a fixed length at the cutting position. It is characterized by: a main vice, which is used to hold the heat sink before and after the cutting position; The head clamp is used to hold the heat sink and transfer it to the cutting position; the stopper is blocked by the front side of the front heat sink group from the front side of the front heat sink group by the front side of the heat sink in the cutting position in the transport direction. The root part is used to regulate the reference length of the front fin side of the base plate part; the stopper driving equipment is used to advance and retreat the stopper for the reference position; the propeller, ° C: \ Program Files \ patent \ P-14〇7.ptd Page 21 157152 Active ^ ° Fixed-length cutting of the heat sink as described in item 2 of the patent scope: Second, the middle stopper driving equipment, which has a structure in which the fluid pressure is not in the forward and upward direction of the heat sink in the cutting position. And the stopper holding table L is connected to the piston rod of the cylinder; and the stopper on the stopper holding table is aligned with the reference position by the telescopic operation of the cylinder. Advance and retreat drive 4 · The fixed length cutting device of the heat sink as described in item 2 of the scope of the patent application, in which the drive device of the pusher is equipped with: the trolley can be moved forward and backward in the transport direction of the heat sink; A trolley driving mechanism is used to drive the trolley; and a pusher support cylinder is mounted on the trolley along its moving direction; and the pusher support cylinder is composed of a rear side fixed cylinder fixed to the trolley and a front side movable The tube is inserted into the fixed tube with free telescoping; the spring is interposed between the two tubes and excites the movable tube to the front; and the pusher is fixed at the front end of the movable tube. . 5. The fixed-length cutting device for the heat-dissipating material as described in item 2 of the scope of the patent application, wherein the heat-dissipating material is formed by arranging the heat-radiating fins in the length direction of the substrate portion in two rows, and arranging two heat-radiating fins The space part is formed across the entire length of the heat sink, and the main vise and the feed vise are divided into two parts. C: \ Program Fi 1 es \ patent \ Pl 407. ptd page 22 157152 6. The scope of patent application is as follows: fixed vise to support the bottom of the heat sink; and movable vise to locate the fixed tiger Above the vise; the movable vise is inserted and disengaged from the space between the two heat sink groups of the heat sink supported on the fixed vise, and the substrate part of the heat sink is between the fixed vise Forms a fixed grip.
