Description

냉간단조법에 의한 차량용 배터리 터미널 플레이트의 제조방법 및 제조장치Manufacturing method and apparatus for manufacturing battery terminal plate for vehicle by cold forging method
본 발명은 냉간단조법에 의한 차량용 배터리 터미널 플레이트의 제조방법 및 제조장치에 관한 것으로, 더욱 상세하게는 차량용 배터리 단자에 결합되는 터미널과 결합되어 사용되는 터미널 플레이트를 냉간단조법을 이용하여 쉽고 균일한 형상으로 제조하는 배터리 터미널 플레이트의 제조방법 및 제조장치에 관한 것이다.The present invention relates to a method and apparatus for manufacturing a battery terminal plate for a vehicle by a cold forging method, and more particularly, to a terminal plate used in combination with a terminal coupled to a vehicle battery terminal by using a cold forging method The present invention relates to a method for manufacturing a battery terminal plate and an apparatus for manufacturing the same.
차량용 배터리에 사용되는 배터리 터미널은 별도의 배터리 터미널 플레이트에 조립되어 사용되는데, 종래 배터리 터미널 플레이트의 제조방법으로는 부피체로 이루어진 피가공 재료를 여러 개의 프레스기로 옮겨가면서 여러 번의 프레스 가공을 통해 기본적인 형태로 성형한 후(프레스/단조가공), 불필요한 부분을 잘라내고(트리밍가공), 표면을 가공하여 마무리되고 있다.The battery terminal used for a vehicle battery is assembled and used in a separate battery terminal plate. In the conventional method of manufacturing a battery terminal plate, the material to be processed in bulk is transferred to a plurality of presses, and then presses several times to form a basic form. After molding (press / forging), unnecessary parts are cut out (trimming), and the surface is processed to finish.
그러나 이러한 종래 배터리 터미널 플레이트 제조방법은 피가공 재료를 여러 개의 프레스기로 옮겨가면서 가공을 하게 되므로, 피가공재료는 몰론, 가공장치의 이동경로가 길어져 생산 효율이 크게 떨어지는 문제가 있다.However, the conventional method for manufacturing a battery terminal plate is to be processed while moving the workpiece material to a plurality of presses, there is a problem that the processing material is, of course, a long movement path of the processing device is greatly reduced production efficiency.
더욱이 피가공 재료 자체의 부피가 큰 경우, 프레스 과정에서 프레스기 사이로 넘쳐 불필요한 자투리 부분이 발생하게 되는 문제점이 있으며, 이를 제거하기 위해 별도의 바렐 작업과, 표면을 세척하여 매끄럽게 정리하는 표면 마무리 단계를 거쳐야 하므로, 결과적으로 제조 과정이 길어져 제조시간 및 제조단가 상승되는 문제가 있다.Moreover, when the volume of the material to be processed itself is large, there is a problem in that unnecessary parts are overflowed between press machines during the press process. In order to remove this, a separate barrel work and a surface finishing step of cleaning and smoothing the surface must be performed. Therefore, as a result, there is a problem that the manufacturing process is lengthened and the manufacturing time and manufacturing cost are increased.
또한 종래 배터리 터미널 플레이트 제조방법으로 제조된 배터리 터미널 플레이트는 그 크기가 일정치 않고 표면이 거칠게 되므로, 표면 코팅이 균일하게 코팅되지 못하고, 그 결과 배터리 부품을 접속시키거나 고정할 경우, 제품 특성에 영향을 주어 제품의 질을 떨어뜨리고 불량률을 높이게 되는 원인을 제공하게 된다.In addition, since the battery terminal plate manufactured by the conventional method for manufacturing a battery terminal plate is not uniform in size and rough on the surface, the surface coating is not uniformly coated, and as a result, when connecting or fixing the battery parts, it affects the product characteristics To provide a cause for poor product quality and increased failure rates.
