본 발명은 특수차량의 방탄그릴 용접체를 제작하기 위하여 주 핵심 부품인 루버(LOUVER)를 일정한 간격으로 배열하여 고정하는 기존의 결합방법을 개선하여 구조강도 및 탄 충격에 의한 방호성능을 향상시키기 위한 특수 차량의 방탄 그릴 및 그 제작방법에 관한 것이다.The present invention is to improve the protection performance by structural strength and impact impact by improving the existing coupling method of arranging and fixing the louver (LOUVER) as the main core parts at regular intervals in order to manufacture bulletproof grill welds of special vehicles It relates to a bulletproof grill of a special vehicle and a method of manufacturing the same.

종래, 특수 차량의 그릴 루버 연결 구조가 한국등록특허 제262875호(등록일: 2000년05월09일)에 개시되어 있다.Conventionally, a grill louver connection structure of a special vehicle is disclosed in Korean Patent No. 262875 (Registration Date: May 09, 2000).

이는 장갑차량 등의 특수차량 그릴의 루버와 프레임의 연결장치에 있어서 금속코어와 비금속 케이싱을 가진 루버의 이용시 금속코어가 프레임부재의 고정판과 풀을 수 있게 또는 풀을수 없게 연결되어 있고, 이 경우 이 고정판은 홀을 가지며, 이 홀을 통해 상기 금속코어가 연결수단을 가져오기 위한 각각의 루버에 접근되는 것을 특징으로 하고 있다.When the louver of a special vehicle grille such as an armored vehicle is connected to a frame with a louver having a metal core and a non-metal casing, the metal core is connected to the fixing plate of the frame member or unresolved. The fixing plate has a hole, through which the metal core is approached to each louver for bringing the connecting means.

그러나 이러한 연결구조를 사용하여 제작된 방탄 그릴은 루버의 소재가 금속코어와 비금속 외피로 적층된 이종재질의 구성으로 인하여 구조물로 제작시 용접작업이 어렵다는 것이다.However, the bulletproof grille manufactured using such a connection structure is difficult to weld when fabricating the structure due to the heterogeneous material in which the louver material is laminated with a metal core and a non-metal shell.

특히 용접부내에 비금속 외피부가 존재하므로 이는 결함부로 존재되며, 또한 용접시 충분히 용입이 되지않으므로 용접강도가 약하게 나타난다.In particular, since the non-metallic skin is present in the weld, it is present as a defect, and the weld strength is weak because it is not sufficiently penetrated during welding.

따라서 그릴 조립체의 구조 강도 및 방탄성능에 있어서 외부 충격 및 탄 충격에 의한 루버의 탈거가 쉽게 발생될 소지가 크다.Therefore, in the structural strength and ballistic performance of the grill assembly, detachment of the louver due to external impact and bullet impact is likely to occur easily.

따라서 본 발명은 상기와 같은 제반적인 사정을 감안하여 창출된 것으로, 이종재질로 구성된 프로파일 형태의 루버를 확실히 용착시켜 용접강도 및 방탄성능을 향상시키며 작업성이 용이한 특수 차량의 방탄 그릴 및 그 제작방법을 제공하는데 그 목적이 있다.Therefore, the present invention was created in view of the above-mentioned circumstances, and welded the louver of the profile form composed of dissimilar materials to improve welding strength and bulletproof performance, and easy to work. The purpose is to provide a method.
