Description

도어 인너 패널의 드레인 홀 형성방법{THE METHOD FOR FORMING DRAIN HOLE OF DOOR INNER PANEL}Drain hole formation method of door inner panel {THE METHOD FOR FORMING DRAIN HOLE OF DOOR INNER PANEL}

본 발명은 도어 인너 패널의 드레인 홀 형성방법에 관한 것으로, 보다 상세하게는 도어의 드레인 홀의 형성과정에서 버(BURR)의 발생을 방지하도록 하는 도어 인너 패널의 드레인 홀 형성방법에 관한 것이다.The present invention relates to a method of forming a drain hole of a door inner panel, and more particularly, to a method of forming a drain hole of a door inner panel to prevent the occurrence of burrs (BURR) in the process of forming a drain hole of the door.

일반적으로 도어 패널(DOOR PANEL) 하단에는 드레인 홀(DRAIN HOLE)이 형성된다. In general, a drain hole is formed at the bottom of the door panel.

이러한 드레인 홀의 도어를 구성하는 도어 인너 패널(DOOR INNER PANEL)을 소정의 펀치(PUNCH)를 통한 피어싱(PIERCING) 작업으로 전단 가공하여 형성된다.The door inner panel (DOOR INNER PANEL) constituting the door of such a drain hole is formed by shearing by a piercing operation through a predetermined punch.

도 1은 도어 인너 패널을 개략적으로 도시한 도면이고, 도 2는 도 1의 Ⅱ-Ⅱ 선 단면도이다.1 is a view schematically illustrating a door inner panel, and FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1.

도 1 및 도 2에 도시된 바와 같이, 도어(1) 하단에 마련되는 드레인 홀(3)은 도어 인너패널(7)을 피어싱 펀치(5)로 피어싱 작업을 통한 전단 가공으로 형성되는데, 이러한 피어싱 작업된 단면은 도 2에 도시된 바와 같이 버(BURR)(9)가 발생된다. 이러한 버(BURR)(9)는 선단이 날카롭게 형성됨으로 도어 아우터 패널(DOOR OUTER PANEL)내부로 뚫고 들어갈 수 있음으로써, 도어에 굴곡이 발생될 수 있는 문제점이 있다.1 and 2, the drain hole 3 provided at the bottom of the door 1 is formed by shearing through the piercing operation of the door inner panel 7 with the piercing punch 5, which is pierced. The worked cross section is generated with a burr 9 as shown in FIG. Since the burr 9 has a sharp tip, the burr 9 can penetrate into the door outer panel, thereby causing a problem in the door.

본 발명은 상기 전술한 바와 같은 문제점들을 해결하기 위해 창출된 것으로서, 도어의 드레인 홀의 형성과정에서 버(BURR)의 발생을 방지하도록 하는 도어 인너 패널의 드레인 홀 형성방법을 제공하는데 그 목적이 있다.An object of the present invention is to provide a method for forming a drain hole of a door inner panel to prevent generation of burrs (BURR) in a process of forming a drain hole of a door.

상기 목적을 달성하기 위한 본 발명의 도어 인너 패널의 드레인 홀 형성방법은, 도어 인너 패널과 도어 아우터 패널로 형성된 도어에 마련되는 드레인 홀의 형성방법에 있어서, 상기 드레인 홀은 도어 인너 패널의 가압부재의 가압으로 인한 포밍으로 형성되는 것을 특징으로 한다.In the method for forming a drain hole of the door inner panel of the present invention for achieving the above object, in the method for forming a drain hole provided in the door formed of the door inner panel and the door outer panel, the drain hole is the pressure member of the door inner panel Characterized in that formed by the foaming due to the pressing.

본 발명에 있어서, 상기 드레인 홀은 가압부재의 가압으로 상기 도어 인너 패널의 상부패널이 인입되어 상기 도어 아우터 패널과 근접되도록 형성되는 것을 특징으로 한다.In the present invention, the drain hole is characterized in that the upper panel of the door inner panel is drawn in close proximity to the door outer panel by the pressing of the pressing member.

이하 본 발명의 바람직한 실시예에 따른 도어 인너 패널의 드레인 홀 형성방법을 첨부된 도면을 참조하여 상세히 설명한다. 그러나 본 발명은 이하에서 개시되는 실시예에 한정되는 것이 아니라 서로 다른 다양한 형태로 구현될 것이며, 단지 본 실시예는 본 발명의 개시가 완전하도록 하며, 통상의 지식을 가진자에게 발명의 범주를 완전하게 알려주기 위해 제공되는 것이다.Hereinafter, a method of forming a drain hole of a door inner panel according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the present embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you.

도 3은 본 발명의 바람직한 실시예에 따른 도어 인너 패널의 드레인 홀을 개략적으로 도시한 도면이고, 도 4는 도 3의 A-A 선 단면도이다.3 is a view schematically illustrating a drain hole of a door inner panel according to a preferred embodiment of the present invention, and FIG. 4 is a cross-sectional view taken along line A-A of FIG.

도 3 및 도 4에 도시된 바와 같이, 본 발명에 따른 도어 인너 패널의 드레인 홀(10)은 가압부재(20)의 가압으로 인한 포밍으로 형성된다.3 and 4, the drain hole 10 of the door inner panel according to the present invention is formed by forming due to the pressing of the pressing member 20.

상기 드레인 홀(DRAIN HOLE)(10)은 도어 인너 패널(DOOR INEER PANEL)(11)이 가압부재(20)의 가압으로 인한 포밍(FORMING)됨에 의하여 형성되는 것으로서, 가압부재(20)는 드레인 홀 형성부의 도어 인너패널(11)을 인입시킴으로 도어 아우터 패널(13)과 근접되도록 형성한다. The drain hole 10 is formed by forming a door inner panel 11 by the pressing of the pressing member 20, and the pressing member 20 is a drain hole. The door inner panel 11 is formed to be close to the door outer panel 13 by drawing in the forming portion.

이에 따라, 드레인 홀(10)은 도어 인너 패널(11)이 인입되어 도어 아우터 패널(13)과 근접되도록 형성됨으로써, 드레인 홀(10)의 형성과정에서 그 근접부에 금형구조의 취약부가 발생되는 현상을 방지한다. 또한, 드레인 홀(10)의 형성과정에서 종래 전단 가공시 발생되는 버(BURR)의 발생을 방지할 수 있음으로서, 버가 아우터 패널(13)을 뚫고 들어가 외관굴곡이 발생됨을 방지한다.As a result, the drain hole 10 is formed such that the door inner panel 11 is inserted into the door outer panel 13 so that the weak part of the mold structure is generated in the vicinity of the drain hole 10. Prevent the phenomenon. In addition, it is possible to prevent the occurrence of the burr (BURR) generated during the conventional shearing process in the process of forming the drain hole 10, the burr penetrates through the outer panel 13 to prevent the appearance bend.

상기와 같은 본 발명에 따른 도어 인너 패널의 드레인 홀 형성방법은 다음과 같은 효과를 갖는다.The drain hole forming method of the door inner panel according to the present invention as described above has the following effects.

드레인 홀의 형성과정에서 버(BURR)의 발생을 방지하도록 함으로써, 버에 의한 도어 외관의 굴곡됨을 방지할 수 있다.By preventing the occurrence of the burr BURR during the formation of the drain hole, it is possible to prevent the door from being bent by the burr.

또한, 도어 외관의 굴곡시에 외관 굴곡을 제거하기 위한 작업시간이 절감된다.In addition, the working time for removing the appearance of the curvature during the bending of the door appearance is reduced.

이상, 본 발명을 도면에 도시된 실시예를 참조하여 설명하였다. 그러나, 본 발명은 이에 한정되지 않고 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명과 균등한 범위에 속하는 다양한 변형예 또는 다른 실시예가 가능하다. 따라서, 본 발명의 진정한 보호범위는 이어지는 특허청구범위에 의해 정해져야 할 것이다.The present invention has been described above with reference to the embodiments shown in the drawings. However, the present invention is not limited thereto, and various modifications or other embodiments falling within the scope equivalent to the present invention are possible by those skilled in the art. Therefore, the true scope of protection of the present invention should be defined by the following claims.
