본 발명은 이종 블랭크재를 이용한 차량용 도어패널의 생산방법에 관한 것으로, 상세하게는 차량용 도어패널의 제작시 외력이 작용하는 정도를 고려하여 각기 다른 두께를 갖는 이종 블랭크재를 접합시켜 구성하므로써 도어의 제작공정을 단순화하는 한편, 우수한 내구력을 갖도록 한 이종 블랭크재를 이용한 차량용 도어패널의 생산방법에 관한 것이다.The present invention relates to a method for producing a door panel for a vehicle using a dissimilar blank material, and in detail, in consideration of the degree of external force acting when manufacturing the door panel for the vehicle by combining the different blank material having a different thickness of the door The present invention relates to a method for producing a door panel for a vehicle using a different blank material to simplify the manufacturing process and to have excellent durability.

일반적으로 차량용 도어패널은, 도어의 외관을 이루는 외판과 상기한 외판을 지지하는 동시에 도어에 작용하는 외력에 견디기 위해 적절한 강성을 갖도록 한 내판으로 구성되며, 차체와의 연결을 위해 힌지가 부착되는 부위에는 제1도에 도시한 바와같이 용접에 의해 내판(32)의 일측에 별도의 보강부재(33)를 부착시키므로써 도어패널(30)의 자중에 따른 처짐이나 변형을 방지하게 된다.Generally, a door panel for a vehicle is composed of an outer plate forming the exterior of the door and an inner plate supporting the outer plate and having an appropriate rigidity to withstand the external force acting on the door, and a hinge portion for connection to the vehicle body. As shown in FIG. 1, by attaching a separate reinforcing member 33 to one side of the inner plate 32 by welding, sagging or deformation due to the weight of the door panel 30 is prevented.

한편, 종래에는 상기한 바와같은 도어패널(30)의 제작시, 프레스작업에 의해 도어패널(30)의 형상에 따라 내판(32)과 보강부재(33)를 소정의 형상을 갖도록 각각 성형하고, 스포트 용접에 의해 상기한 내판(32)과 보강부재(33)를 일체로 접합시킨 다음, 내판(32)의 표면에 외판(31)을 접촉시킨 상태에서 외판(31)의 엣지를 헤밍(hemming)작업을 통해 내판(32)의 내측으로 절곡시켜 도어패널(30)을 구성하게 된다.Meanwhile, when manufacturing the door panel 30 as described above, the inner plate 32 and the reinforcing member 33 are respectively molded to have a predetermined shape according to the shape of the door panel 30 by pressing. The inner plate 32 and the reinforcing member 33 are integrally bonded by spot welding, and then the edge of the outer plate 31 is hemmed while the outer plate 31 is brought into contact with the surface of the inner plate 32. Through the operation, the inner panel 32 is bent into the door panel 30.

그러나, 상기한 바와같은 종래의 도어패널 제작방법은, 프레스 작업을 통해 내판(32) 및 외판(31)과 보강부재(33)를 각각 별도로 생산한후, 내판(32)과 보강부재(33)를 용접에 의해 접합시킨 상태에서 외판(31)을 해밍작업을 통해 내판(32)의 내측으로 절곡시켜야 하므로 생산공정이 복잡하여 생산성이 저하되었으며, 내판(32)과 보강부재(33)의 접합작업시 내판(32)과 보강부재(33)간의 두께 및 강성의 차이에 따라 내판(32)에 변형이 발생하는등의 많은 문제점이 발생하였다.However, in the conventional door panel manufacturing method as described above, after the inner plate 32 and the outer plate 31 and the reinforcing member 33 are separately produced through a press operation, the inner plate 32 and the reinforcing member 33 are produced. The outer plate 31 to be bent into the inner plate 32 through a hamming operation in the state of welding by welding, the production process is complicated, the productivity is reduced, the bonding operation of the inner plate 32 and the reinforcing member 33 According to the difference in thickness and stiffness between the inner plate 32 and the reinforcing member 33, many problems such as deformation of the inner plate 32 occurred.

본 발명에 의한 이종 블랭크재를 이용한 차량용 도어패널의 생산방법은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 차량용 도어의 제작을 용이하게 할 수 있도록 하는 한편, 우수한 내구성을 갖도록 하여 도어패널의 처짐이나 변형을 방지하도록한 차량용 도어패널의 제작방법을 제공하는데 있는 것이다.The production method of a vehicle door panel using a dissimilar blank material according to the present invention has been devised in view of the above-described conventional problems, and an object of the present invention is to facilitate the manufacture of a vehicle door, and to provide excellent durability. It is to provide a method of manufacturing a door panel for a vehicle so as to prevent sagging or deformation of the door panel.

상기와 같은 목적을 달성하기 위한 본 발명의 특징은, 각긱 다른 두께의 블랭크재를 요구되는 강성에 따라 소정의 형상으로 각각 절단하는 단계와, 상기한 각 블랭크재를 CO2레이져용접에 의해 일체로 접합하여 내판을 형성하는 단계와, 일체로 접합된 내판을 프레스로 성형하는 단계와, 성형이 완료된 내판을 헤밍에 의해 외판과 결합시키는 단계로 이루어진 것이다.A feature of the present invention for achieving the above object is the step of cutting each blank material of different thicknesses into a predetermined shape according to the required rigidity, and each of the blank materials integrally by CO 2 laser welding. Bonding and forming the inner plate, forming the integrally bonded inner plate by a press, and combining the completed inner plate with the outer plate by hemming.

이하, 본 발명에 의한 이종 블랭크재를 이용한 차량용 도어패널의 생산방법을 첨부된 도면을 참조하여 구체적으로 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, a method for producing a vehicle door panel using a heterogeneous blank material according to the present invention will be described in detail.

제2도는 본 발명의 블록도, 제3도는 블랭크재의 평면도이고, 제4도는 이종 블랭크재의 폭방향 단면을 도시한 도면으로서. 본 발명에 의한 이종 블랭크재를 이용한 차량용 도어패널의 생산방법은, 도어패널(10)의 내판(2)을 구성하는 블랭크재(A,B)를 요구되는 강성에 따라 각긱 다른 두께로 구성하므로써 힌지연결부와 같이 많은 외력이 작용하게되어 강성이 요구되는 부위는 두께가 두꺼운 블랭크재(A)를 소재로 하여 소정의 형상으로 절단시키고, 외력이 적게 작용하는 부위는 도어패널(10)의 경량화를 위해 얇은 블랭크재(A)를 소정의 형상으로 각각 절단시키며, 상기한 과정후에는 균일한 용접면을 얻을 수 있고 접합부위에 대한 열적변형이 적은 CO2레이저 용접기에 의해 상기한 각 블랭크재(A,B)를 일체로 접합시켜 내판(2)를 구성하게 된다.FIG. 2 is a block diagram of the present invention, FIG. 3 is a plan view of a blank material, and FIG. 4 is a view showing a cross section in the width direction of the different blank material. The method for producing a door panel for a vehicle using a dissimilar blank material according to the present invention is hinged by configuring the blank materials A and B constituting the inner plate 2 of the door panel 10 in different thicknesses depending on the required rigidity. Many external force acts like a connection part, and the part requiring rigidity is cut into a predetermined shape by using a thick blank material (A) as a material, and the part where the external force acts to reduce the weight of the door panel 10. Each of the blank materials A and B is cut into a predetermined shape, and after the above process, a uniform welding surface can be obtained and each of the blank materials A and B is made by a CO 2 laser welder with less thermal deformation to the joint. ) Is integrally joined to form the inner plate 2.

상기한 바와같이 블랭크재(A,B)의 접합에 따라 내판(2)의 구성이 완료되면, 통상의 작업방법과 같이 상기한 내판(2)을 금형에 밀착시킨 상태에서 프레스작업을 통해 소정의 형상으로 가공을 하게 되며, 상기한 작업의 완료후에는 외판(1)의 엣지를 헤밍에 의해 내판(2)의 내측으로 절곡시켜 외판(1)과 내판(2)을 일체화시키게 되며, 상기한 과정후에는 통상의 도어 제작작업과 같이 도장작업과 내장재 및 유리창부착등의 후처리작업을 실시하여 작업을 완료하게 된다.As described above, when the configuration of the inner plate 2 is completed by the joining of the blank materials A and B, a predetermined work is performed by pressing in the state in which the inner plate 2 is brought into close contact with the mold as in the usual working method. After completion of the above work, the edge of the outer plate 1 is bent into the inner plate 2 by the hemming to integrate the outer plate 1 and the inner plate 2 by the hemming, the process described above Afterwards, the work is completed by painting work, post-treatment work such as interior materials and glass window attachment as in normal door manufacturing work.
