Description of the Invention: [Technical Field] The present invention relates to a method for manufacturing a columnar heat sink, the manufacturing process comprising (1) extrusion molding (2) cutting forming into a columnar shape (3) continuous punching Hole die punching and shaping (4) A plurality of heat sinks are tightly coupled and the like, and a columnar heat sink is quickly manufactured. [Prior Art] f know that the heat sink 'is mainly composed of - the heat sink module and the base of the base'. The heat sink module is composed of a plurality of heat sinks arranged in a spaced adjacent arrangement. In addition, in response to the demand for high heat dissipation power, more than one heat pipe has been combined. The heat sink or the base is usually made of a metal or copper metal. The base is used (copper bottom or at the bottom) to guide the crystal heat source. Cooling function. In addition, the conventional small heat sink also has a plurality of heat dissipation plate blocks arranged in parallel at the base, so that the base guides the crystal heat source to the heat dissipation plate block to achieve the purpose of heat dissipation, but the small heat sink is small in size. Simple structure and low cost, but the heat dissipation power is low, often can not meet: general = requirements; or another configuration of combined heat pipe I know the heat dissipation is very powerful, but it is bulky, complex and It is also not suitable for general heat dissipation power requirements; therefore, it can be seen that if the heat pipe radiator is used for low heat dissipation, it will appear to be oversupply, resulting in unnecessary waste and economical, so the heat dissipation power is insufficient, so the heat sink and the crystal heat source are If the exothermic power can be matched, it is the best combination. It is the best heat sink design of 200934365. It should refer to the radiator that can meet the actual heat dissipation requirements. It is not suitable for over and under. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for manufacturing a columnar heat sink by (1) extrusion molding (2) cutting and forming into a column shape (3) continuous punching die punching The shaping (4) heat sink is tightly coupled with a manufacturing process, and a base having a plurality of columns can be completed at a speed, and can be closely combined with a plurality of heat sinks to complete a columnar heat sink, and the overall manufacturing is simplified. It is not very fast and is very suitable for mass production of consistent operations. A secondary object of the present invention is to provide a method for manufacturing a columnar heat sink, which is capable of performing continuous punching work by using a plurality of arrays of punching dies provided by a continuous punching die, and using a multi-array punching die The sequence of the plurality of columns of the base is subjected to continuous multi-station roughing and fine punching, so that the cylinder can be precisely formed by one process, so that the heat sink can be matched and inserted into the majority of the cylinders to be tightly coupled and quickly completed. Column radiator. Another object of the present invention is to provide a method for manufacturing a columnar heat sink. The base can be freely increased or decreased according to various heat dissipation power requirements, and can be appropriately increased when the heat dissipation power demand is high. Increase the number of heat sinks, and vice versa, so that the most appropriate heat dissipation power can be accurately supplied to meet various heat dissipation requirements, which fully meets the requirements of structural simplicity and cost-effectiveness. Another object of the present invention is to provide a method for manufacturing a columnar heat sink. When punching and shaping a punching die, the multi-array punching die is selected to have a relatively matching shape according to various punching shapes. Punching 200934365 ίThe formation of a variety of different shapes of the cylinder, so that the bottom chain of the hot column 盥 round hole ': +:: 匕 ' can be set to rectangular column and rectangular hole, round pair; = state column and length Slots or other regular or irregular phases [Embodiment] ❹ Detailed description is as follows « 〇丨_1 , 糸 sequentially through (1) extrusion molding (2) cutting: hole die punching and shaping (4) heat sink tight fit and other main =? = (1)Extrusion ······································································ In the case of the type, it is cut along the sheet material (4) to form a plurality of cylinders 12 (such as the == the size of each cylinder 12 will have a rough error: each (3), = punching die punching and shaping: It is matched with multiple arrays, and the two punches are arranged in the same manner as the punching die 2 (as shown in the fourth figure). 12 Simultaneous multi-station 7 200934365 5th to 9th), the cylinder 12 is precisely formed; (4) The heat sink is tightly coupled: after the cylinder 12 is accurately formed, the plurality of heat sinks 3 are sequentially arranged. Matching the majority of the cylinders 12 nested in the base 1 to form a tight fit (as shown in the tenth figure), a columnar heat sink (such as a Η-图) can be quickly completed. As shown in the fourth figure, in the rudimentary state, the base 1 is matched with a plurality of punching dies 2 having a plurality of punches in the punching and punching of the continuous punching die (the fourth figure only shows the punching of one of the groups). The second rough punch is performed on the plurality of cylinders 12 of the base 1 and the plurality of punches 21 of the punching die 2 are relatively matched with the plurality of cylinders 12, and an auxiliary upper die 4 is used. Figure 7) The porous punching die 2 can be pressed down to punch each of the opposite cylinders 12, so that each of the cylinders 12 originally has a prototype with a dimensional error, which is uniform, so that a multi-array punching die is used in sequence. (The punching die 2 used in sequence has only a slight difference in the size of the punching holes 21, for example, the diameter of the punching holes used before and after is only 0.05 mm further), so that the plurality of columns 12 of the base 1 pass through the plurality of times. The punching, such as the fifth and sixth figures, shows that the punching can be achieved by five or six roughing and fine punching (the number of punching can be increased or decreased as needed), so that the cylinder 12 is completely accurate. Molding, so the size of each of the cylinders 12 has now reached the same uniformity. The auxiliary upper mold 4 is provided with a plurality of ejector pins 41 corresponding to the plurality of columns 12, and when the punching is performed, the auxiliary upper mold 4 is automatically lowered and penetrates the porous punching die 2, The plurality of jacks 41 are correspondingly supported by the plurality of cylinders 12, so that the punching die 2 can be driven to punch the cylinder 12 to ensure stability during the cutting stroke, of course, The mold 200934365 4 is also matched with each set of punching dies 2, so each punching die 2 has a set of auxiliary upper dies 4 opposite to each other, and each set of ejector pins 41 of the auxiliary upper die 4 has a size The punching holes 21 of the punching dies 2 are the same.

On the platform, using the rotary drive or other transmission movement method, the base 1 can be accepted for each movement - the punching of the group punching die 2 'after the punching of the multi-array punching die 2, all the columns can be made The bodies 12 are all precisely formed in exactly the same size. 7 to 9 are schematic views showing a state in which the punching die 2 of the porous form is respectively subjected to the punching of the plurality of cavities 12 of the base 1, and each of the nuclei 2 is punched with a specific size thereof. The punching cylinder 12 for the punching process of the cylinder 12 is punched once by a punching die 2, and is slightly reduced in size (can be selected to reduce (4) 2 faces to read the face each time, and 0.05mm is appropriate). As shown in the ninth figure, the dusting stroke of each punching die 2 is only close to the root 13 of the cylinder 12, and after the continuous multi-station processing, the root 13 will be chamfered. During the cutting process, some small metal chips 121 are scraped off. As shown in the tenth figure, the above-mentioned base 1 can be seen by various heat dissipation work, and the number of heat sinks 3 can be increased or decreased arbitrarily. When the heat dissipation power demand is relatively small, the number of heat sinks can be increased by an appropriate amount, and vice versa. Therefore, it can supply the most appropriate heat dissipation power to meet various heat dissipation requirements. , the tenth to the seventeenth, the multi-array punching die 2' can be selected according to the needs of various punching shapes (four) to open a relatively matching shape of the 200934365 punching holes 21 A to 21F (such as a cross hole) Shapes such as rectangular holes, circular holes, hexagonal holes, double-angle holes, and long-slot holes) are formed by punching a plurality of columns 11 of the base 1 into various shapes to match the heat sink 3 having relatively matching openings. So that the heat sink 3 can be combined with a plurality of cylinders π. Similarly, the punching of the punching die 2 is not limited to the one shown in the figure, and may be other shapes or arbitrary regular or irregular shapes if necessary. Of course, the plural cylinders have the same shape.
