Description

  The present invention relates to a radiator, and more particularly, to a manufacturing method used for a radiator in which radiating fins are assembled on a metal substrate.

  In recent years, LEDs (light-emitting diodes) are gradually replacing conventional light sources, but if the temperature of the LED modules of LED lighting fixtures is not controlled below 80 ° C, electrical energy is converted into light energy instead of heat energy. The characteristics of low energy consumption and low heat quantity of the LED lighting apparatus obtained by the above cannot be exhibited. Therefore, the LED module can quickly dissipate heat by attaching a radiator having a large number of heat radiation fins to the LED lighting apparatus.

  By the way, general radiators are mainly classified into laminated radiating fins and aluminum molding. Multilayer radiating fins connect a number of radiating fins in series with each other in order to form an annular body in which the top and end are connected, and are welded onto the substrate to form a radiator. Therefore, the heat conduction resistance of the welding surface between the radiating fin and the substrate is increased, making it difficult to meet the need for high heat conduction, and it requires two steps of processing time, requiring considerable labor and manufacturing costs. To increase. On the other hand, the production flow of aluminum-molded radiating fins is to manufacture a set of aluminum-molded modules, extrude the aluminum material, cut to the actual size of the radiating fin, polish the cut edge, and finally anodize Since the appearance is made beautiful, the entire manufacturing process becomes too complicated, so that the production efficiency cannot be increased, and the entire manufacturing cost is also expensive.

  Therefore, the present inventor considers that the above-mentioned drawbacks can be improved, and accumulates related experience in this direction for many years, observes and researches in detail, and also uses the theory to effectively solve the above-mentioned drawbacks with rational design. This invention proposes an improved invention.

  An object of the present invention is to provide a method of manufacturing a radiator that can be manufactured quickly, reduce unnecessary assembly processes, greatly increase production efficiency, and reduce manufacturing costs.

  Based on the above object, the present invention presents a method of manufacturing a radiator that combines a metal substrate and X heat dissipating fins, where X is a natural number, and the manufacturing method is in an alignment moving mechanism of a processing machine base. The metal substrate is installed on a jig, the metal substrate is manufactured by a punching method, and Y slots corresponding to the X radiation fins are provided around the metal plate, and a processing machine base A material preparation step of attaching a metal material belt to the metal material belt, an alignment step in which the alignment movement mechanism moves the jig, and the jig and the metal substrate correspond to below the metal material belt, and the metal material A punch formed by punching positioning holes at both ends of the belt at equal intervals, allowing a positioning pin to enter the positioning hole, and continuously punching a large number of the radiation fins on the metal material belt. A step of curving and curving the radiating fin, and the processing machine base moves the radiating fin of the metal material belt to align the radiating fin and the slot of the metal substrate. In addition, when the cutting module of the processing machine table squeezes and cuts the radiating fin, and when the radiating fin is inserted into the slot, the pressing blade tip on the processing machine table is pressed in both directions, A step of pressing the upper and lower surfaces located on both sides of the slot of the metal substrate to plastically deform the metal substrate and cutting the both side wall surfaces of the slot into close contact with both surfaces of the radiating fins and fastening by pressing means And rotating the jig to rotate the metal substrate 1 / Y according to Y slots and repeating the cutting and pressing with the pressing means (X-1) times, The process is repeated (Y-1) times so that the other radiating fins on the metal belt are sequentially incorporated into the (Y-1) slots, and the metal substrate and the X that have already been combined are combined. The heat radiation fins are taken out from the jig to take out the heat radiator.

  The effect of the present invention is that the heat radiation fins are continuously pushed out by the metal material belt on the processing machine table, and the heat radiation fins are sequentially inserted on the metal substrate to plastically deform the metal substrate. By fixing the heat dissipation fins and configuring the heatsink by automation, it is not necessary to weld the heat dissipation fins onto the metal substrate by the welding method, so the problem of increased heat conduction resistance due to welding can be prevented. The manufacturing process of the present invention is simplified and quicker than that of aluminum molding, so that the production efficiency can be greatly increased and the manufacturing process can be greatly reduced. It has the effect of reducing costs and the like.

I believe it will be understood. However, the attached drawings are only provided for reference and explanation and do not impose any limitations on the present invention.

  As shown in FIGS. 1 and 2, the present invention presents a method of manufacturing a radiator for manufacturing a radiator that combines a metal substrate 1 and X radiating fins 51 by automation. X is a natural number, and the manufacturing method includes the following steps. That is, the material preparation step (S100), the alignment step (S200), the punching step (S300), the rolling and bending step (S400), the cutting and pressing step (S500), the rotation step (S600), the cutting and It is a repetition process (S500) and a rotation process (S600) by a pressing means, and an extraction process (S700).

  As shown in FIG. 3, in the material preparation step (S100), the metal substrate 1 is manually placed on the jig 40 of the pair of alignment movement mechanisms 30 on the processing machine base 3, Position on the jig 40. Further, the metal substrate 1 is a circular plate and is manufactured by a punching method, and the periphery of the metal substrate 1 is punched through Y slots 11 (see FIG. 2) corresponding to the above-described X radiation fins 51. Then, a metal material belt 50 as a material of the heat radiation fin 51 is attached on the processing machine base 3.

  More specifically, as shown in FIG. 2A, a number of metal substrates 1 are continuously or simultaneously punched on the metal material plate 100 by a metal punching technique, and further, as shown in FIG. After the completion, the Y slots 11 are punched out around the metal substrate 1, but the metal substrate 1 can be quickly manufactured by manufacturing the metal substrate 1 by a punching method. Further, the positioning hole 12 is pushed out on the metal substrate 1.

  In the alignment step (S200), when the alignment moving mechanism 30 moves the jig 40, the jig 40 and the metal substrate 1 move to position them below the metal material belt 50. Yes.

  In the punching step (S300), the punching mechanism (not shown) on the processing machine table 3 is first formed on both side ends of the metal material belt 50 (both ends in a direction substantially perpendicular to the traveling direction of the metal material belt 50). In addition, the positioning holes 52 (see the reference numeral A in FIG. 3) are punched out at equal intervals, and positioning pins (not shown) are inserted into the positioning holes 52 to position the metal belt 50 accurately and reliably. In addition to preventing displacement, a number of heat dissipating fins 51 (refer to reference numeral D in FIG. 3) are continuously punched out on the metal material belt 50 by the punching mechanism with the connecting portion 55 remaining.

  In the punching step (S300), after the positioning hole 52 is punched out, the embossed portions 53 (refer to the location of symbol B in FIG. 3) are further embossed on both surfaces of the metal material belt 50 to Increase heat dissipation surface area. Then, the punch hole 54 (refer to the position indicated by the symbol C in FIG. 3) is punched out of the metal material belt 50, but the punch hole 54 may not be punched out. Subsequently, a predetermined outer mold at one end of the radiating fin 51 is first pushed out on the metal material belt 50, and then a predetermined outer mold at the other end of the radiating fin 51 (reference numeral in FIG. 3). Press D). In this embodiment, as shown in FIG. 3, the left end is first pushed out and then the right end is pushed out. However, the left end can also be pushed out after first pushing out the right end. Finally, the method further includes a step of scraping off the sharp edge of the heat dissipating fin 51 that has been punched out (refer to the portion indicated by E in FIG. 3).

  In the reduction and bending step (S400) (refer to the portion indicated by F in FIG. 3), the radiating fin 51 is crushed to bend the connecting portion 55, that is, a part of the radiating fin 51 is still a metal material. It remains connected to the belt 50.

  As shown in FIG. 4 to FIG. 6, in the cutting step and the fastening step by the pressing means (S 500), the processing machine base 3 moves the radiating fins 51 on the metal material belt 50 and radiates heat to the slot 11 of the metal substrate 1. The heat radiation fin 51 and the slot 11 of the metal substrate 1 are aligned so that the fin 51 corresponds. Then, the cutting module 60 on the processing machine base 3 is squeezed down to cut the connecting portion 55 so that the heat radiation fin 51 partially connected to the metal material belt 50 is separated from the metal material belt 50 and the heat radiation fin 51 Is inserted into the slot 11 and then, as shown in FIG. 7, both sides of the slot 11 of the metal substrate 1 are pressed by pressing blade tips 70 as pressing means on the processing machine table 3 from both directions. By pressing the upper and lower surfaces positioned on each other, the metal substrate 1 is plastically deformed at this portion, and the opposite side wall surfaces in which the slots 11 are formed are brought into close contact with both surfaces of the radiating fins 51. Secure the heat radiation fins 51 firmly.

  When the above steps are completed, the rotation step (S600) is performed. In this step, the jig 40 rotates, and the metal substrate 1 is moved in the circumferential direction of the metal substrate 1 according to the Y slots 11. When 1 / Y rotation is performed, the next slot 11 can be aligned with the next radiation fin 51 to be inserted.

  Here, the cutting step and the fastening step (S500) by the pressing means are repeated (X-1) times, the rotation step (S600) is repeated (Y-1) times, and the other heat radiation fins on the metal material belt 50 are obtained. 51 are sequentially incorporated into the (Y-1) slots 11.

  When the duplication process is completed, an extraction process (S700) is performed. In this process, the metal substrate 1 and the X radiation fins 51 that have already been combined are removed from the jig 40, and the radiator. Get. Here, as shown in FIGS. 3 and 8, when the first alignment step (S200) is completed, the alignment moving mechanism 30 is prepared next in any step after the alignment step (S200). The step of placing the jig 40 ′ and the metal substrate 1 ′ can be further included, and constitutes a preparation step. When the assembly of the radiator is completed, the alignment step (S200) of the prepared metal substrate 1 ′ can be repeated. In performing the alignment step (S200) of the prepared jig 40 ′, The prepared jig 40 'pushes the assembled radiator and jig 40 from the side (that is, the direction perpendicular to the longitudinal direction of the metal belt 50) (in FIG. And push upwards). Thereafter, the metal substrate 1 that has been assembled can be subjected to the extraction step (S700), and the next metal substrate 1 ′ that has not yet been assembled is sequentially aligned to the alignment step (S200) or this position. A large number of radiators can be quickly manufactured by repeating the steps after the matching step (S200). Although the metal substrate 1 is a circular plate, this is advantageous in that the radiating fins 51 are inserted into the slots 11 of the metal substrate 1 in order and accurately, and the rotation step (S600). This is also advantageous for purposes such as accuracy during 1 / Y rotation.

  In the present invention, the above is a natural number X, preferably 10 or more, but if it is 10 or less, the heat dissipating effect provided by the heat dissipating fins deteriorates. In the present embodiment, as shown in the attached drawings, there are 30 heat dissipating fins 51 of the heat dissipator, so X is 30 as an example. Accordingly, since there are 30 slots 11 on the metal substrate 1, the heat radiation fin 51 is clamped 30 times by the pressing means on the processing machine base 3.

  In the present invention, in the rotation step (S600), the jig 40 is connected to the servo rotation mechanism 80 below the jig 40, so that the metal substrate 1 is stepped by 1 / Y rotation by the Y slots 11. This produces a formula rotation. Positioning pins 41 are attached to the jig 40, and the positioning holes 12 through which the positioning pins 41 are inserted are pushed out from the metal substrate 1 to position the metal substrate 1 on the jig 40.

  The alignment moving mechanism 30 includes a fixed base 31 fixed to a side end of the processing machine base 3, a propulsion rod 32 movably incorporated in the fixed base 31, and a rail unit 33 provided on the fixed base 31 and the processing machine base 3. The bottom of the jig 40 is recessed with a slot 42 that is slidably in contact with the rail unit 33, and the propulsion rod 32 corresponds to the jig 40 and the jig 40 is moved by the rail unit 33. It can be made to slide and correspond to the lower part of the metal belt 50.

  The cutting module 60 has a cutting punch 61 that can move up and down, cuts the radiating fins 51 on the metal belt 50, and puts the radiating fins 51 in the corresponding slots 11 of the metal substrate 1. Insert.

  To sum up the above explanation, the present invention continuously pushes the heat radiating fins on the processing machine table with a metal belt, and gradually inserts the heat radiating fins on the metal substrate and presses the substrate from above and below to radiate heat. Since the fin is fixed and the heat radiator is configured by automation, and it is not necessary to weld the heat radiating fin onto the metal substrate by a welding method, it is possible to prevent the problem that the heat conduction resistance is increased by welding. In addition, the manufacturing process is quick, and unnecessary assembly processes are reduced. Compared with aluminum molding, the manufacturing process of the present invention is simplified and quick, so that the production efficiency can be greatly increased, and the manufacturing cost is reduced. Has an effect.
