도 4는 본 발명의 제1실시예에 의한 루버 핀의 성형방법의 a) 단계가 수행되는 상황을 개략적으로 도시한 것이다.4 schematically shows a situation in which step a) of the method for forming a louver pin according to the first embodiment of the present invention is performed.
도 4에 도시된 바와 같이, 본 발명의 제1실시예에 의한 루버 핀의 성형방법의 a) 단계는 일측으로 연장 형성된 박막부재(100)의 표면 중, 루버 핀의 절단부가 형성될 부분인 제거예정 영역(50)의 테두리 중 일부를 절개하여, 1차 절개부(101)를 형성한다. 제거예정 영역(50)은 도 3에 도시된 1차 절개부(101)와, 1차 절개부(101)의 끝단에서 수직한 방향으로 박막부재(100)의 외측 단부로 연장된 가상의 선인 제1기준선(L1) 및 제2기준선(L2)을 둘러싸인 영역일 수 있다.As shown in Fig. 4, step a) of the method for forming a louver pin according to the first embodiment of the present invention is to remove the portion where the cut portion of the louver pin is to be formed from the surface of the thin film member 100 extending to one side. A part of the edge of the predetermined area 50 is cut to form the primary cutout 101. The region to be removed 50 is a first cut-out portion 101 shown in FIG. 3 and a first cut-off portion 101, which is a virtual line extending from the end of the first cut-off portion 101 to the outer end of the thin film member 100 in a vertical direction. It may be an area surrounding the first reference line L1 and the second reference line L2.
a) 단계에서 1차 절개부(101)를 형성할 때, 적어도 하나 이상의 커터가 사용될 수 있으며, 본 실시예에서는 도 4에 도시된 바와 같이 상부 커터(61)와 하부 커터(62)가 박막부재(100)의 상부와 하부 각각에서 박막부재(100)를 절개할 수 있다. 상부 커터(61)와 하부 커터(62)는 설정되는 제거예정 영역(50)에 따라, 박막부재(100)가 연장된 방향에서 수직한 수평방향으로의 이동과, 상하방향으로의 이동이 가능하게 설치될 수 있다. 또한 상부 커터(61)와 하부 커터(62)는 각각 별개로 이동하거나, 동시에 이동하면서 박막부재(100)의 일부분을 절개할 수 있다.When forming the first incision 101 in step a), at least one cutter may be used, and in this embodiment, as shown in FIG. 4, the upper cutter 61 and the lower cutter 62 are thin film members. The thin film member 100 may be cut at each of the upper and lower portions of the 100. The upper cutter 61 and the lower cutter 62 enable movement in the vertical and horizontal direction from the direction in which the thin film member 100 extends and in the vertical direction according to the set region to be removed 50. Can be installed. In addition, the upper cutter 61 and the lower cutter 62 may move separately or move at the same time to cut a portion of the thin film member 100.
a) 단계에서 박막부재(100)는 박막부재(100)가 연장된 일측으로 이동하면서 상부 커터(61) 및 하부 커터(62)에 의해 일부분이 절개되어, 1차 절개부(101)를 형성할 수 있으나, 본 발명은 상부 커터(61)와 하부 커터(62)가 1차 절개부(101)를 형성하는 방법을 이에 한정하지는 않으며 고정된 박막부재(100)를 커터가 움직이며 절개하는 실시예 또한 있을 수 있다.In step a), the thin film member 100 is partially cut by the upper cutter 61 and the lower cutter 62 while moving to one side where the thin film member 100 extends, thereby forming the primary cutout 101. However, the present invention is not limited to the method of forming the primary incision 101 by the upper cutter 61 and the lower cutter 62, and an embodiment in which the cutter moves and cuts the fixed thin film member 100 There may also be.
도 4에 도시된 본 실시예에서 제거예정 영역(50)은 직사각형이지만, 본 발명은 이에 한정하지 않고 제거예정 영역(50) 또는 절개부는 다각형, 원형 또는 타원형과 같은 다양한 형상일 수 있으며, 이에 관해서는 본 발명의 제1실시예에 의한 루버 핀의 절단형상 성형방법의 나머지 단계들을 설명한 후에 상세히 설명한다.Although the region to be removed 50 in the present embodiment shown in FIG. 4 is a rectangle, the present invention is not limited thereto, and the region to be removed 50 or the cutout may have various shapes such as polygons, circles, or ellipses. Will be described in detail after explaining the remaining steps of the method for forming a cut shape of a louver pin according to the first embodiment of the present invention.
a) 단계에서 형성하는 제거예정 영역(50) 테두리 중 일부분인 1차 절개부(101)의 방향은 루버 핀이 절곡되는 방향, 즉 박막부재(100)가 연장된 방향과 동일할 수 있다. 이렇듯 본 발명의 제1실시예에 의한 루버 핀 성형방법에서 1차 절개부(101)를 박막부재(100)가 연장되는 방향과 동일한 방향으로 형성하는 이유는, b) 단계에서 박막부재(100)가 해당 방향으로 절곡되어 루버 핀을 형성하는데, 루버 핀이 제조된 후에는 루버 핀의 주름 구조의 특성상 루버 핀이 절곡된 방향으로 절단하는 것이 용이하지 않고, 박막부재(100)의 두께가 얇아 절단하는 과정에서 루버 핀의 표면에 형성된 루버가 파손되어, 루버 핀 자체의 성능이 저하될 수 있기 때문이다.The direction of the first cutout 101, which is a part of the edge of the region to be removed 50 formed in step a), may be the same as the direction in which the louver pin is bent, that is, the direction in which the thin film member 100 extends. As described above, in the method for forming the louver pin according to the first embodiment of the present invention, the reason why the first cutout 101 is formed in the same direction as the direction in which the thin film member 100 extends is, in step b), the thin film member 100 Is bent in the corresponding direction to form a louver pin.After the louver pin is manufactured, it is not easy to cut it in the direction in which the louver pin is bent due to the characteristic of the corrugated structure of the louver pin, and the thickness of the thin film member 100 is thin. This is because the louver formed on the surface of the louver pin may be damaged during the process, and the performance of the louver pin itself may be deteriorated.
a) 단계에서 제거예정 영역(50) 테두리 전부를 절개하지 않는 이유는 박막부재(100)가 b) 단계에서 폼 롤에 삽입되어 절곡됨으로써 루버 핀으로 제조되기 때문이다. 보다 상세히, 박막부재(100)는 제거예정 영역(50)이 제거된 상태로 폼 롤에 삽입될 경우, 불균일한 박막부재(100)의 형상 때문에 박막부재(100)와 폼 롤 사이에 응력이 발생하여, 특정 부분이 과도하게 절곡되는 등의 불량품이 나올 수 있기 때문이다.The reason why the entire edge of the region to be removed 50 is not cut in step a) is that the thin film member 100 is inserted into and bent into a foam roll in step b), thereby manufacturing a louver pin. In more detail, when the thin film member 100 is inserted into the foam roll while the region 50 to be removed is removed, stress is generated between the thin film member 100 and the foam roll due to the uneven shape of the thin film member 100 This is because defective products such as excessive bending of certain parts may be produced.

도 5에 도시된 바와 같이, b) 단계는 a) 단계에서 1차 절개부(101)가 형성된 박막부재(100)를 상부 폼 롤(71)과 하부 폼 롤(72) 사이에 삽입하여 루버 핀(110)을 제조하는 단계이며, b) 단계가 수행되어 제조되는 루버 핀(110)은 상측 절곡부(111)와 하측 절곡부(112)가 반복적으로 형성된다. 또한, 상부 폼 롤(71)과 하부 폼 롤(72)의 톱니의 표면에는 루버 핀(110)의 상측 절곡부(111)와 하측 절곡부(112) 사이에 루버를 형성하기 위한 부재가 형성되어 있을 수 있다.As shown in FIG. 5, step b) is a louver pin by inserting the thin film member 100 on which the primary cutout 101 is formed in step a) between the upper foam roll 71 and the lower foam roll 72. It is a step of manufacturing (110), and the louver pin 110 manufactured by performing step b) has an upper bent portion 111 and a lower bent portion 112 repeatedly formed. In addition, a member for forming a louver is formed between the upper bent portion 111 and the lower bent portion 112 of the louver pin 110 on the surfaces of the teeth of the upper foam roll 71 and the lower foam roll 72. There may be.

도 7에 도시된 바와 같이, 상측 절곡부(111)와 하측 절곡부(112) 사이에는 복수개의 루버(113)가 루버 핀(110)의 폭 방향으로 다수개 형성되어 있으며, 도 6 및 도 7에 도시된 바와 같이 a) 단계에서 형성된 1차 절개부 또한 루버 핀(110)의 형상에 따라 절곡된 상태로 변형되어 있다. 이하 편의상 b) 단계에서 절곡된 1차 절개부를 최종 절개부(102)라 한다. 상술한 제거예정 영역(절단부가 형성될 부분)은 도 6에 표시되지 않았지만, 제1기준선(L1), 제2기준선(L2) 및 최종 절개부(102)로 둘러싸인 부분이 제거예정 영역으로 추후 제거될 부분이다.As shown in FIG. 7, a plurality of louvers 113 are formed in the width direction of the louver pin 110 between the upper bent part 111 and the lower bent part 112, and FIGS. 6 and 7 As shown in FIG. 1, the first incision formed in step a) is also deformed in a bent state according to the shape of the louver pin 110. Hereinafter, for convenience, the first incision bent in step b) is referred to as the final incision 102. Although the above-described region to be removed (the part where the cutout is to be formed) is not shown in FIG. 6, the region surrounded by the first reference line L1, the second reference line L2, and the final cutout 102 is removed later as the region to be removed. This is the part to be.

Thereafter, in step c), the pressing member 83 located on the upper portion of the louver pin 110 is moved downward at a sufficient speed to remove the region 50 to be removed. That is, the pressing member 83 serves as a kind of punch. One surface of the pressing member 83 contacting the region 50 to be removed of the louver pin 110 may be a flat surface, but may be formed corresponding to the shape of the surface of the region 50 to be removed. When the region to be removed 50 is a rectangle, one side (bottom) of the pressing member 83 is also a rectangle having the same width and shape as the region to be removed 50, or protrudes in a wavy shape like the surface of the louver pin 110 Can be.

As a result, economical efficiency and heat transfer efficiency can be improved compared to a heat exchanger of a method in which a conventional plain fin and a louver fin are mixed and applied as described in the background art.
앞서 도 3 내지 도 9에서는 절단부(51)가 루버 핀(110)의 일측 단부에서 내측으로 연장된 형상을 설명하였으나, 절단부(51)는 루버 핀(110)의 내부에 형성되거나, 사각형이 아닌 원형 또는 타원형과 같이 다양한 형상일 수 있다.In FIGS. 3 to 9, a shape in which the cutting part 51 extends inward from one end of the louver pin 110 has been described, but the cut part 51 is formed inside the louver pin 110 or is a circular shape rather than a square. Alternatively, it may have various shapes such as an oval.
도 10은 본 발명의 제1실시예에 의한 루버 핀의 절단형상 성형방법에서 다양한 형상의 절단부(51)를 형성하는 과정을 개략적으로 도시한 것이다. 도 9의 하부에 도시된 박막부재(100)는 a) 단계가 수행된 이후의 박막부재(100)이며, 중앙 부분에 도시된 루버 핀(110)은 b) 단계가 수행된 이후의 루버 핀(110)이고, 상부에 도시된 루버 핀(110)은 c) 단계가 수행된 이후의 루버 핀(110)이다.10 schematically illustrates a process of forming the cut portions 51 of various shapes in the method of forming the cut shape of the louver pin according to the first embodiment of the present invention. The thin film member 100 shown in the lower part of FIG. 9 is the thin film member 100 after the step a) is performed, and the louver pin 110 shown in the center portion is a louver pin after the step b) is performed. 110), and the louver pin 110 shown at the top is the louver pin 110 after step c) is performed.
도 10A는 앞서 도 4 및 도 9를 참조하여 설명한 절단부(51)가 루버 핀(110)의 일측 단부에서 내측으로 연장된 형상인 경우를 도시한 것이며, 이 경우 절단예정 영역(50)과 절단부(51)는 직사각형이되, 절단부(51)가 절단예정 영역(50)보다 작은 면적으로 구성된다.FIG. 10A shows a case in which the cutting part 51 described above with reference to FIGS. 4 and 9 has a shape extending inward from one end of the louver pin 110, in this case, the area to be cut 50 and the cut part ( 51) is a rectangle, but the cut portion 51 is configured to have a smaller area than the area to be cut 50.
도 10B는 루버 핀(110) 내부에 홀 형태의 절단부(51)가 형성되는 과정을 도시한 것이다. 도 10B에 도시된 바와 같이, 홀 형태의 절단부(51)를 포함하는 루버 핀(110)의 경우, a) 단계에서 제거예정 영역(50)의 테두리 중 박막부재(100)가 연장된 방향으로 형성된 테두리를 절개하여 복수개의 1차 절개부(101)를 형성한 후, b) 단계와 c) 단계를 수행하여 최종적으로 홀 형태의 절단부(51)를 포함하는 루버 핀(110)을 제조한다. 도 10B에 형성된 홀 형태의 절단부(51)를 형성하는 과정에서 단일의 박막부재(100)에 형성된 복수개의 1차 절개부(101) 중 일부는 서로 일정 간격 이격되어, 대칭하도록 구성될 수 있으며, 서로 대칭으로 일정 간격 이격된 1차 절개부(101) 사이는 박막부재로 이어질 수 있다.10B shows a process in which the cut portion 51 in the form of a hole is formed in the louver pin 110. As shown in FIG. 10B, in the case of the louver pin 110 including the cut portion 51 in the form of a hole, the thin film member 100 is formed in an extended direction among the edges of the region to be removed 50 in step a). After the rim is cut to form a plurality of primary cutouts 101, steps b) and c) are performed to finally manufacture the louver pin 110 including the cutout 51 in the form of a hole. In the process of forming the hole-shaped cutting portion 51 formed in FIG. 10B, some of the plurality of primary cutting portions 101 formed in the single thin film member 100 may be spaced apart from each other by a predetermined interval and may be configured to be symmetrical, Between the primary cutouts 101 spaced apart symmetrically at a predetermined interval may lead to a thin film member.
도 10A 및 도 10B에 도시된 바와 같이, 1차 절개부(101)의 길이는, 동일한 1차 절개부(101)가 절곡되어 형성되는 최종 절개부(102)의 길이보다 길다. 또한 도 10A 및 도 10B에서 1차 절개부(101)의 방향은 박막부재(100)가 연장 형성된 방향과 동일한데, 본 발명은 1차 절개부(101)의 방향을 이에 한정하는 것은 아니며 b) 단계가 수행될 때, 박막부재(100)가 정상적인 루버 핀(110)으로 절곡될 수 있다면 1차 절개부(101)는 어떠한 방향으로 형성될 수 있다.As shown in FIGS. 10A and 10B, the length of the first cutout 101 is longer than the length of the final cutout 102 formed by bending the same first cutout 101. In addition, the direction of the first cutout 101 in FIGS. 10A and 10B is the same as the direction in which the thin film member 100 is extended, but the present invention does not limit the direction of the first cutout 101 thereto b) When the step is performed, if the thin film member 100 can be bent into a normal louver pin 110, the primary cutout 101 can be formed in any direction.
도 10C는 홀 형태이되, 원형의 절단부(51)를 루버 핀(110)에 형성하는 과정을 도시한 것이다. 도 10C에 도시된 바와 같이, 홀 형태이되, 원형의 절단부(51)를 포함하는 루버 핀(110)의 경우, a) 단계에서 제거예정 영역(50)의 테두리 중 일정길이 이상의 테두리를 절개하여 1차 절개부(101)를 형성하며, 이 과정에서 모든 1차 절개부(101)의 총 길이는 제거예정 영역(50)의 총 테두리 길이의 일정 기준 범위 이내일 수 있으며, 바람직하게는 50~70%일 수 있다. 모든 1차 절개부(101)의 총 길이를 상기한 바와 같이 일정 기준 범위로 제한하는 이유는 b) 단계에서 박막부재(100)의 변형이 발생하지 않으면서도 c) 단계에서 제거예정 영역(50)을 보다 용이하게 제거하기 위한 것이다. 단, 본 발명은 제거예정 영역(50)의 총 테두리 길이 대비 1차 절개부(101)의 길이를 상기한 수치에 한정하지 않으며, 반복 실험의 결과로 제거예정 영역(50)의 총 테두리 대비 1차 절개부(101)의 길이가 결정될 수 있다.10C shows a process of forming a hole-shaped, circular cut portion 51 in the louver pin 110. As shown in FIG. 10C, in the case of the louver pin 110 having a hole shape, but including a circular cut portion 51, in step a), an edge of a predetermined length or more among the edges of the region to be removed is cut 1 The primary incision 101 is formed, and in this process, the total length of all the primary incisions 101 may be within a certain reference range of the total edge length of the area to be removed 50, preferably 50 to 70 It can be %. The reason for limiting the total length of all the primary cutouts 101 to a certain reference range as described above is that the region 50 to be removed in step c) without deformation of the thin film member 100 in step b). It is to remove more easily. However, the present invention is not limited to the length of the first incision 101 relative to the total edge length of the region to be removed 50 to the above value, as a result of repeated experiments compared to the total edge of the region to be removed 50 The length of the difference cutout 101 may be determined.
아울러, 최종적으로 원형의 절단부(51)를 형성하기 위해서는 박막부재(100)상에서 박막부재(100)가 연장된 방향이 더 긴 타원형의 제거예정 영역(50)을 설정해야 하는데, 이는 b) 단계를 거치면서 평판형의 박막부재(100)가 접혀 루버 핀(110)이 형성되기 때문에, b) 단계에서 타원형의 제거예정 영역(50)의 장축이 줄어들어 최종적으로 원형의 절단부(51)가 형성되기 때문이다.In addition, in order to finally form the circular cut portion 51, it is necessary to set the elliptical shape to be removed from the thin film member 100 in the direction in which the thin film member 100 extends, which is step b). Because the louver pin 110 is formed by folding the flat thin film member 100 while passing through, the long axis of the elliptical region to be removed 50 in step b) is reduced, thereby finally forming a circular cut portion 51 to be.

도 11은 본 발명의 제2실시예에 의한 루버 핀 성형방법의 순서도이다.11 is a flow chart of a method for forming a louver pin according to a second embodiment of the present invention.
도 11에 도시된 바와 같이, 본 발명의 제2실시예에 의한 루버 핀 성형방법은 d) 단계, e) 단계, f) 단계 및 g) 단계를 포함할 수 있다.As shown in FIG. 11, the method of forming a louver pin according to the second embodiment of the present invention may include steps d), e), f) and g).
d) 단계는 박막부재(100)를 폼 롤에 삽입하여 상측 절곡부(111)와 하측 절곡부(112)가 반복적으로 형성되고, 상기 상측 절곡부(111)와 상기 하측 절곡부(112) 사이에 루버(113)가 형성된 루버 핀(110)을 제조하는 단계이다. 본 발명의 제2실시예에 의한 루버 핀 성형방법의 d) 단계는 앞서 설명한 본 발명의 제1실시예에 의한 루버 핀 성형방법의 b) 단계와 나머지 부분은 동일하되, 1차 절개부(101)가 형성되지 않은 온전한 형태의 박막부재(100)를 폼 롤에 삽입한다는 점을 제외하면 동일하므로, 별도의 도면을 통해 설명하지 않는다.In step d), an upper bent portion 111 and a lower bent portion 112 are repeatedly formed by inserting the thin film member 100 into the foam roll, and between the upper bent portion 111 and the lower bent portion 112 This is a step of manufacturing the louver pin 110 in which the louver 113 is formed. Step d) of the louver pin molding method according to the second embodiment of the present invention is the same as step b) of the louver pin molding method according to the first embodiment of the present invention described above, but the first cutout 101 It is the same except that the intact thin film member 100 in which) is not formed is inserted into the foam roll, and thus will not be described with reference to a separate drawing.
도 12는 본 발명의 제2실시예에 의한 루버 핀 성형방법의 e) 단계 및 f) 단계가 수행되는 과정을 개략적으로 도시한 것이다.12 schematically shows a process in which steps e) and f) of the method for forming a louver pin according to a second embodiment of the present invention are performed.
도 12에 도시된 바와 같이, 본 발명의 제2실시예에 의한 루버 핀 성형방법의 e) 단계는 일측에 다수개의 돌출부(92)가 형성된 하부 금형(91)에 상기 상측 절곡부(111)의 하면이 상기 돌출부(92)의 끝단에 지지되도록 상기 루버 핀(110)을 거치한다. 루버 핀(110)의 상측 절곡부(111)의 하면이 돌출부(92)의 끝단에 지지된 상태에서 하측 절곡부(111)는 하부 금형(91)의 저면(93)과 맞닿지 않고 이격되어야 하는데, 이는 f)단계가 수행될 때 하측 절곡부(111)가 손상되지 않도록 하기 위함이다. 상기한 바와 같은 이유로, 돌출부(92)가 하부 금형의 저면으로부터 돌출된 높이는 상측 절곡부(111)의 끝단에서 하측 절곡부(112)의 끝단까지 수직한 높이, 즉 루버 핀(100)의 높이보다 길다.As shown in FIG. 12, step e) of the method for forming a louver pin according to the second embodiment of the present invention includes the upper bent portion 111 in the lower mold 91 having a plurality of protrusions 92 formed on one side thereof. The louver pin 110 is mounted so that the lower surface is supported at the end of the protrusion 92. In the state that the lower surface of the upper bent part 111 of the louver pin 110 is supported by the end of the protruding part 92, the lower bent part 111 should be spaced apart without contacting the lower surface 93 of the lower mold 91. , This is to prevent damage to the lower bent portion 111 when step f) is performed. For the above reasons, the height of the protrusion 92 protruding from the bottom surface of the lower mold is a height perpendicular from the end of the upper bent part 111 to the end of the lower bent part 112, that is, the height of the louver pin 100 long.
도 12에 도시된 바와 같이, f) 단계에서 커터(90)는 루버 핀(110)의 상부에서 루버 핀(110) 방향으로 이동해, 루버 핀(110)의 절단부가 형성될 부분인 제거예정 영역(50)의 테두리들 중 일부인 상측 절곡부(111)를 절개한다. 즉, 커터(90)는 상측 절곡부(111)를 가압하여 절개하며, 이때 커터(90)는 일측으로 연장형성되고, 루버 핀(110)에 상측 절곡부(111)와 하측 절곡부(112)가 반복 형성된 방향(박막부재가 절곡된 방향, 박막부재가 연장된 방향과 동일함)으로 배치되어, 다수개의 상측 절곡부(111)를 동시에 제거할 수 있다. 이때 커터(90)는 절개 대상인 상측 절곡부(111)를 한 번에 절개할 수 있거나, 다수번 반복 수행을 통해 절개 대상 상측 절곡부(111)를 절개할 수 있도록, 커터(90)가 연장 형성된 길이는 절개 대상인 상측 절곡부(111)가 배치된 길이 이하가 되도록 할 수 있다. 또한, 하부 금형(91)의 상면 중, 돌출부(92)가 형성된 면적은, 루버 핀(110)의 제거예정 영역의 면적보다 넓거나 같을 수 있다. 이는 커터(90)를 이용하는 f) 단계에서 보다 안정적으로 상측 절곡부(111)를 절개할 수 있게 하기 위함이다.As shown in FIG. 12, in step f), the cutter 90 moves from the top of the louver pin 110 in the direction of the louver pin 110, and the region to be removed, which is the part where the cut portion of the louver pin 110 is to be formed ( The upper bent part 111, which is part of the edges of 50), is cut. That is, the cutter 90 is cut by pressing the upper bent portion 111, at this time the cutter 90 is formed to extend to one side, the upper bent portion 111 and the lower bent portion 112 on the louver pin 110 Is arranged in a repeatedly formed direction (the same as the direction in which the thin film member is bent and the direction in which the thin film member is extended), so that a plurality of upper bent portions 111 can be simultaneously removed. At this time, the cutter 90 can incise the upper bent portion 111 to be cut at a time, or the cutter 90 is formed to be extended so that the upper bent portion 111 to be cut can be cut through a number of iterations. The length may be less than or equal to the length at which the upper bent portion 111 to be cut is disposed. In addition, an area of the upper surface of the lower mold 91 in which the protrusions 92 are formed may be larger than or equal to the area of the area to be removed of the louver pin 110. This is to allow the upper bent portion 111 to be cut more stably in step f) using the cutter 90.
도 13은 f) 단계가 수행된 이후의 루버 핀(110)을 도시한 것이며, 도 14는 도 13에 도시된 루버 핀(110)을 확대 도시한 것이다.FIG. 13 shows the louver pin 110 after step f) is performed, and FIG. 14 is an enlarged view of the louver pin 110 shown in FIG. 13.
도 13 및 도 14에 도시된 바와 같이, f) 단계가 수행된 이후에 루버 핀(110)은 절단부가 형성될 부분인 제거예정 영역(50)의 상측 절곡부(111)가 절개되어 상측 절개부(103)가 형성된 것을 확인할 수 있다. 만약 상측 절개부(103)가 형성된 상태의 루버 핀(110)을 펴 박막부재를 만든다면, 제거예정 영역의 테두리 중 일부에 상측 절개부(103)가 일정 간격으로 배치된 형상일 것이다.13 and 14, after the step f) is performed, the upper bent portion 111 of the region to be removed 50, which is a portion to be cut, is cut to the louver fin 110 It can be seen that (103) was formed. If the louver pin 110 in which the upper cutout 103 is formed is opened to form a thin film member, the upper cutout 103 will be arranged at regular intervals on some of the edges of the region to be removed.
g) 단계는 상기 제거예정 영역(50)의 나머지 테두리를 절단하여 절단부(51)를 형성하는 단계로, 상술한 본 발명의 제1실시예에 의한 루버 핀의 절단형상 성형방법의 c) 단계와 동일한 방법을 사용하여 제거예정 영역(50)의 나머지 테두리를 절단해 절단부(51)를 형성할 수 있으며, 이 과정에서 f) 단계에서 형성된 상측 절개부(103)가 일종의 절단 보조역할을 해, 제거예정 영역(50)의 나머지 테두리를 절단하는 것을 보다 용이하게 할 수 있다.Step g) is a step of cutting the remaining edge of the region to be removed 50 to form a cut portion 51, and step c) of the method for forming a cut shape of a louver pin according to the first embodiment of the present invention described above and Using the same method, the remaining edge of the area to be removed 50 can be cut to form the cut 51, and in this process, the upper incision 103 formed in step f) serves as a kind of cutting aid and is removed. It is possible to make it easier to cut the remaining edges of the predetermined area 50.
단, 이와 같은 본 발명의 제2실시예에 의한 루버 핀 성형방법은 f) 단계에서 제거예정 영역(50)의 상측 절곡부(111)만을 절개하기 때문에, g) 단계에서 절단부(51)의 성형이 용이하지 않을 수 있다. 따라서 본 발명의 제2실시예에 의한 루버 핀의 절단형성 성형방법은 f) 단계와 g) 단계 사이에 수행되는 e-1) 단계 및 f-1) 단계를 더 포함할 수 있다.However, since the louver pin molding method according to the second embodiment of the present invention cuts only the upper bent portion 111 of the region to be removed 50 in step f), the cutting portion 51 is formed in step g). This may not be easy. Accordingly, the method for forming a cut-formed louver pin according to the second embodiment of the present invention may further include steps e-1) and f-1) performed between steps f) and g).
e-1) 단계는 제거예정 영역(50)의 상측 절곡부(111)가 절개된 루버 핀(110)을 뒤집어, 하측 절곡부(112)의 하면이 돌출부(92)의 끝단에 지지되도록 루버 핀(110)을 거치한다. 즉, e-1) 단계에서 루버 핀(110)은 도 12에 도시된 루버 핀(110)을 뒤집어져 상측 절곡부(111)와 하측 절곡부(112)의 위치가 서로 뒤바꾼다. e-1) 단계에서 하측에 위치한 상측 절곡부(111)는 e) 단계에서의 하측 절곡부(112)와 마찬가지로 하부 금형(91)의 저면(93)과 이격된 상태이다.Step e-1) is to reverse the louver pin 110 in which the upper bent portion 111 of the region to be removed 50 is cut, so that the lower surface of the lower bent portion 112 is supported at the end of the protrusion 92 Mount (110). That is, in step e-1), the louver pin 110 reverses the louver pin 110 shown in FIG. 12 so that the positions of the upper bent part 111 and the lower bent part 112 are reversed. The upper bent portion 111 located at the lower side in step e-1) is in a state spaced apart from the bottom surface 93 of the lower mold 91, similar to the lower bent portion 112 in step e).
f-1) 단계는 커터(90)를 루버 핀(110)의 상부에서 루버 핀(110) 방향으로 이동시켜, 루버 핀(110)의 절단부가 형성될 부분인 제거예정 영역(50)의 하측 절곡부(112)를 절개해, 하측 절개부를 형성한다. 즉, 본 발명은 f) 단계 및 f-1) 단계를 통해, 제거예정 영역(50)의 테두리 중 일부에 위치한 상측 절곡부(111)와 하측 절곡부(112) 모두를 절개하여, g) 단계에서 제거예정 영역(50)이 보다 용이하게 제거되도록 할 수 있다.In step f-1), the cutter 90 is moved from the upper portion of the louver pin 110 in the direction of the louver pin 110 to bend the lower side of the region to be removed 50, which is the part where the cut portion of the louver pin 110 will be formed. The part 112 is cut to form a lower cutout. That is, the present invention cuts both the upper bent part 111 and the lower bent part 112 located at some of the edges of the region to be removed 50 through steps f) and f-1), and step g) In the region 50 to be removed can be more easily removed.
f) 단계 및 f-1) 단계에서 사용되는 커터(90)의 두께는, 서로 인접하여 루버 핀(110)의 표면에 형성된 두 개의 루버 사이의 간격보다 작게 형성될 수 있다. 이는 커터(90)의 두께가 서로 인접하여 형성된 두 개의 루버 사이의 간격보다 클 경우, 상측 절곡부(111) 또는 하측 절곡부(112)를 절개할 때, 커터(90)에 의해 루버가 손상될 수 있 때문이다.The thickness of the cutter 90 used in steps f) and f-1) may be formed to be smaller than the gap between the two louvers formed on the surface of the louver pin 110 adjacent to each other. This is because when the thickness of the cutter 90 is greater than the distance between the two louvers formed adjacent to each other, when cutting the upper bent part 111 or the lower bent part 112, the louver may be damaged by the cutter 90. Because you can.
