Abstract

PURPOSE: A hemming process for a hood panel is provided to effectively and efficiently fabricate an incline surface of a panel through the hemming process by facilitating a flange clinching work with respect to both ends of an outer panel when the outer panel is attached to an inner panel. CONSTITUTION: A flange(4) is formed in an outer panel(2) by smoothly bending both ends of the outer panel(2). Then, an inner panel(3), which is smoothly bent, is inserted into the outer panel(2). An upper mold and a lower mold are provided at a clinching surface between the outer panel(2) and the inner panel(3). After that, the flange(4) of the outer panel(2) is pressed at a skin surface at an angle of 110 degrees by using a cam of the upper mold. Then, a hood panel(1) passing through a molding process is placed on the lower mold. In this state, the upper mold moves down so that the inner panel(3) ad the outer panel(4) are partially pressed. Then, the second slider(70) is operated to inwardly bend both ends flange(4) of the outer panel(3). After that, the first slider(60) moves down so as to completely press the flange(4) of the outer panel(3).

Description

후드 패널의 헤밍 가공 방법Hemming method of hood panel

본 발명은 후드 패널의 헤밍 가공 방법에 관한 것으로, 특히 아우터 패널과 인너 패널과의 접합시 아우터 패널 양단부의 플랜지 클린칭을 용이하게 하여 작업능률을 극대화할 수 있는 패널 경사면의 가공 방법에 관한 것이다.The present invention relates to a hemming method of a hood panel, and more particularly, to a method of processing a panel inclined surface that can maximize the work efficiency by facilitating the flange clinching of both ends of the outer panel when the outer panel and the inner panel are joined.

도 1은 종래의 후드 패널(1)의 사시도이고, 도 2는 도 1의 A-A선 단면도이고, 도 3a 도 3b 도 3c 도 3d은 종래의 후드 패널(1) 가공 공정을 나타내는 단면도FIG. 1 is a perspective view of a conventional hood panel 1, FIG. 2 is a cross-sectional view taken along the line A-A of FIG. 1, and FIG. 3A 3B FIG. 3C FIG. 3D is a sectional view showing a conventional hood panel 1 processing process.

동 도면에 의거하여 종래의 후드 패널 가공 방법을 설명한다.The conventional hood panel processing method is demonstrated based on the same figure.

① 양단이 소정각도로 구부려진 후드 아우터 패널(2)을 하형에 놓은 다음 후드 인너 패널(3)을 상기 아우터 패널(2) 상면에 얹는다.① Put the hood outer panel 2 bent at a predetermined angle on the lower mold, and then put the hood inner panel 3 on the upper surface of the outer panel 2.

② 상형(10)이 내려와 인너 패널(3)과 아우터 패널(2)을 부분적으로 누른 상태에서 슬라이더2(40)가 작동하여 아우터 패널(2)의 양단 플랜지(4)를 안으로 구부려 넣은다.② The upper die 10 is lowered and the slider 2 40 is operated while the inner panel 3 and the outer panel 2 are partially pressed to bend the flanges 4 at both ends of the outer panel 2 inward.

③ 슬라이더1(30)이 위에서 내려와 아우터 패널(2)의 플랜지(4)를 완전히 가압해서 헤밍을 마무리 한다.(3) Slider 1 (30) descends from above to completely press the flange (4) of the outer panel (2) to finish the hemming.

따라서, 이러한 양측 패널(2)(3) 헤밍 가공이 능률적이면서 효과적으로 이루어지기 위해서는 아우터 패널(2)의 플랜지(4)가 전개된 상태에서 인너 패널(3)이 상기 아우터 패널(2)내에 진입하여 면접촉되도록 장착되어야 한다. 그렇게 장착되기 위해서는 아우터 패널(2)의 양단 플랜지(4)의 각도 θ가 110도 정도를 유지해야 인너 패널(3)의 장착이 가능해진다.Therefore, in order to achieve efficient and effective hemming of both panels 2 and 3, the inner panel 3 enters the outer panel 2 while the flange 4 of the outer panel 2 is unfolded. It shall be mounted in surface contact. In order to be mounted in such a manner, the inner panel 3 can be mounted only when the angle θ of both flanges 4 of the outer panel 2 is maintained at about 110 degrees.

그러나, 이러한 아우터 패널(2)의 양단 플랜지부(4)가 안쪽으로 많이 오므라 들어 있을 때에는 인너 패널(3)의 양끝이 상기 아우터 패널(2)의 플랜지(4) 선단부에 걸려 진입이 불가능해지는 문제가 있었다.However, when the flanges 4 at both ends of the outer panel 2 are lifted inwardly, both ends of the inner panel 3 are caught by the ends of the flanges 4 of the outer panel 2, thereby preventing entry. There was.

또한, 상기 아우터 패널(2)의 플랜지(4)의 각도 θ가 110도 이상이 되면 슬라이더2(40)가 이동하여 아우터 패널(2)의 플랜지(4)를 안으로 구부렸을 때 스킨에 웨이브(굴곡)이 생기는 등의 문제점이 있었다.In addition, when the angle θ of the flange 4 of the outer panel 2 is 110 degrees or more, the slider 2 40 moves to wave (bending) the skin when the flange 4 of the outer panel 2 is bent inward. There was a problem such as).

패널과 인너 패널과의 결합함에 있어 아우터 패널의 플랜지 각도가 110도를 넘더라도 아우터 패널 내면에 인너 패널이 용이하게 장착되는 동시에 아우터 패널 양단부의 플랜지 클린칭을 용이하게 하여 능률적이고도 효율적인 패널 경사면 헤밍 가공 방법을 도모할 수 있는 것을 과제로 한다.In the combination of the panel and the inner panel, even if the flange angle of the outer panel exceeds 110 degrees, the inner panel is easily mounted on the inner surface of the outer panel, and the flange cleansing of both ends of the outer panel is facilitated, resulting in efficient and efficient panel slope hemming. It is a subject to be able to plan a method.

상기한 과제를 달성하기 위한 본 발명의 구성 및 작용을 첨부도면에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings the configuration and operation of the present invention for achieving the above object is as follows.

① 양단을 완만하게 구부려서 플랜지(4)를 만든 아우터 패널(2)내면에, 양단을 연장하여 완만하게 구부려진 인너 패널(3)을 끼워 장착한다.(1) The inner panel (3), which is bent at both ends and gently bent and extended at both ends, is fitted to the inner surface of the outer panel (2) made of the flange (4).

② 아우터 패널(2)과 인너 패널(3)이 접하여 크린칭되는 면에 상형(10)과 하형(20)으로 지지 구조를 만든 다음, 상형(10)의 캠(30)으로 아우터 패널(2)의 플랜지(4)를 스킨면에 110도 이내로 성형한다.② The upper panel 10 and the lower mold 20 are made of a supporting structure on the surface where the outer panel 2 and the inner panel 3 are in contact with each other, and then the outer panel 2 is formed by the cam 30 of the upper mold 10. Of the flange 4 to the skin surface within 110 degrees.

③ 금형공정을 마친 후드 패널(1)을 하형(50)상면에 얹는 다음 상형(40)이 내려와 인너 패널(3)과 아우터 패널(4)을 부분적으로 누른 상태에서 슬라이더2(70)가 작동하여 아우터 패널(3)의 양단 플랜지(4)를 안으로 구부려 넣은다.③ After the mold process is completed, the hood panel 1 is placed on the upper surface of the lower mold 50, and then the upper mold 40 is lowered, and the slider 2 70 is operated while the inner panel 3 and the outer panel 4 are partially pressed. Bend both flanges (4) of the outer panel (3) inward.

④ 슬라이더1(60)이 위에서 내려와 아우터 패널(2)의 플랜지(4)를 완전히 가압해서 헤밍을 마무리 한다.(4) Slider 1 (60) descends from the top to completely press the flange (4) of the outer panel (2) to finish the hemming.

상기한 방법에 의하면, 아우터 패널(2)의 양단을 완만하게 구부려서 둥글게 플랜지(4)를 형성하고 인너 패널(3)의 양단을 연장하여 둥굴게 형성하고 있기 때문에 아우터 패널(2)내면에 인너 패널(3)면이 용이하게 장착되게 된다.According to the method described above, the inner panel is formed on the inner surface of the outer panel 2 because the flange 4 is formed by gently bending both ends of the outer panel 2, and the both ends of the inner panel 3 are extended and rounded. (3) The surface is easily mounted.

또한, 금형공정으로 아우터 패널(2)의 플랜지(4)를 스킨면에 110도 이내로 성형하기 때문에 헤밍시 스킨면에 굴곡이 생기지 않는다.In addition, since the flange 4 of the outer panel 2 is molded to the skin surface within 110 degrees by a mold process, bending does not occur on the skin surface during hemming.

또한, 금형공정을 마친 패널(1)의 플랜지(4)를 슬라이더2(70)를 작동시켜 아우터 패널(2)의 양단 플랜지(4)를 안으로 구부려 넣은 다음 슬라이더1(60)이 내려와 아우터 패널(2)의 플랜지(4)를 완전히 가압해서 헤밍을 마무리하는 것이기 때문에 아우터 패널(2)의 플랜지(4)의 각도가 110도를 넘더라도 인너 패널(3)의 장착이 용이하고 작업능률을 극대화할 수 있는 것이다.In addition, by operating the slider 2 (70) to the flange (4) of the panel (1) after the mold process, bend the flange (4) at both ends of the outer panel (2) inward, the slider 1 (60) is lowered to the outer panel ( Since the flange 4 of 2) is completely pressed to finish the hemming, even if the angle of the flange 4 of the outer panel 2 exceeds 110 degrees, the inner panel 3 can be easily mounted and the working efficiency can be maximized. It can be.

이상과 같이 본 발명에 의하면, 아우터 패널의 플랜지 각도가 110도를 넘더라도 아우터 패널 내면에 인너 패널이 용이하게 장착되며 또한 헤밍시 스킨면에 굴곡이 생기지 않는 등 작업능률의 향상을 도모할 수 있는 이점이 있는 것이다.As described above, according to the present invention, even if the flange angle of the outer panel exceeds 110 degrees, the inner panel can be easily mounted on the inner surface of the outer panel, and the work efficiency can be improved, such that no bending occurs on the skin surface during hemming. There is an advantage.
