When the invention is explained (), the three pairs of point-shaped clamps 47, 48 , 49; Γ are separated from each other by a distance of D in their initial action positions. The three i are moved by the bearing mechanism 44 to the right by a distance S of the forming jigs 47, 48, 49. In this embodiment , S is twice the width of the chuck. The heat sink 21 formed in this way may have an interval d of 2w. After that, the second pair of forming jigs 48 starts to move above the first pair of forming jigs 47 at an angle. Third, the pair of forming jigs 49 starts to move in a horizontal direction toward the first pair of forming jigs 47 to bend the aluminum plate 30 (sixth figure). As shown in the seventh and eighth figures, in the second and third pairs, After the forming jigs 48 and 49 are moved a distance toward the first pair of forming jigs 47 so that the interposed aluminum plate 30 is bent into a symmetrically inclined state, the chuck 484 under the second pair of forming jigs 48 is turned toward the first pair of forming Below the clamp 47 The aluminum plate 30 is moved away, and the third pair of forming jigs 49, chucks 492, 494 and the second pair of forming jigs 48 chucks 482 are still moved toward the first pair of forming jigs 47 in the original direction. After printing by the Central Engineering Vehicle Bureau of the Ministry of Economic Affairs of the Bayong Consumer Cooperative, the first pair of forming jigs 48 moved all the way to the left of the first pair of forming jigs 47 to a position of 1 / 2W + t; the third pair of forming jigs 49 It moves to a position w + 2t from the left of the first pair of forming jigs 47 (ninth picture). As a result, a heat dissipation plate 21 composed of two closely stacked vertical plate portions 22 and 24 is formed. Its height is D and its width is about 2t. In the present invention, the second pair of forming jigs 48 and the third pair of forming jigs 49 are moved to the right to form the heat sink 21, and the aluminum plate 30 will not be stretched. 30 thickness t can be kept consistent without cracking. 11. The paper size is generally Chinese national standard (CNS} A4 specification (2 丨 OX297 mm) A7 __________B7 _ V. Description of the invention () Yu. Take this' as long as The molding machine 40 has a size large enough to make the height of the heat sink 21 It is infinite. Preferably, the height D of the heat sink 21 is 60 to 100 times the thickness t of the aluminum plate 30. After the heat sink 21 is generated, the fixing chuck 43 can be moved to fix the aluminum plate 30 to the fixing machine. The chucks 472, 492 on the stage 42 and above the first, second and third pairs of forming jigs 47, 48, 49 are moved upward to the heat sink 21 and above (as shown in the tenth figure), among which the chucks 472, 492 At the same height, the collet 482 is located above the collets 472, 492. Printed by the Consumers' Cooperative of the Central Bureau of Prototypes of the Ministry of Economy ¾ In addition, the bearing mechanism 44 drives the three pairs of forming jigs 47, 48, and 49 to move to the left by a distance of S. Next, the upper chuck 472 of the first pair of forming jigs 47 is moved downward to clamp the aluminum plate 30 with the lower chuck 474 thereof, and the lower chuck 484 of the second pair of forming jigs 48 is first upward at an angle. Then it moves horizontally to the left to return to its starting position, and the upper head 482 moves at an angle a to the left and lower to the starting position and the lower chuck 484 tightens the nameplate 30, and the third pair of forming fixtures 49 The lower chuck 494 is moved horizontally to the left to return to its initial position, and the upper chuck 492 is moved to the starting position left and down at an angle b, and the lower chuck 494 clamps the aluminum plate 30 (such as the first Figures thirteen to fifteen are shown here, here b > a). Next, the fixing fixture 43 releases the clamping of the aluminum plate 30 and then repeats the operations of the fifth to thirteenth drawings to generate one vertical heat radiation plate η on the name plate 30 to form the staggered heat radiation plate 21 and the horizontal bottom plate. The heat-dissipating film of 28 ° 20 ° In the machine 40 of the present invention, because the forming fixtures 47, 49 and the inscription 12 are in the paper method, the general Chinese national kneading rate (CNS) A4 specification (2 丨 0X297 cm) A7 B7 V. Description of the invention ( There is only a small contact area between the plates 30, and the forming and clamping fixtures 0, 48, and 49 will not produce a huge demolding force when they are detached from the heat dissipation plate V. Therefore, the machine 40 of the present invention will not crack the heat dissipation fins, Even though the heat sink 21 formed there is a considerable height. Moreover, the heat sink of the heat sink fin of the present invention can have a very smooth surface because there is no huge demolding force, and it is not common on stamping parts. This scratch not only affects the overall appearance, but also is not conducive to heat dissipation. In summary, the method of forming the heat dissipation fin of the present invention is completely different from the conventional method and can achieve a better heat dissipation than conventional methods. The heat dissipation effect of the film, so the present invention can actually obtain the protection of the invention patent. The invention is based on the patent requirements, and filed a patent application according to law. However, the above is only a preferred embodiment of the present invention.
