Abstract

본 발명은 밸브 태핏 본체와 심(Shim)과의 접합을 양호하게하여 엔진의 성능 및 연비를 향상시키고자 한 알루미늄 밸브 태핏(Tappet)제조 방법에 관한 것이다.The present invention relates to a method for manufacturing an aluminum valve tappet to improve the performance and fuel efficiency of the engine by improving the junction between the valve tappet body and the shim.

종래 밸브 태핏의 제조방법에 있어서는 압입방식을 이용하여 특수강 심을 인서트시키게 되므로서, 본체와의 접합이 안정되게 이루어지지 않아 엔진의 성능이 저하되거나, 연비가 나빠지는 문제점이 발생하게 된다.In the conventional method for manufacturing a valve tappet, since a special steel core is inserted by using a press-fit method, the joint with the main body is not made stable, resulting in a problem that the performance of the engine is degraded or the fuel economy is deteriorated.

본 발명에서는 상기에서와 같은 문제점을 해결하기 위하여 반용융상태의 알루미늄 합금을 가압하여 캐비티(Cavity)내에 위치하고 있는 다공질 세라믹에 부분용침 시키므로서, 태핏 본체와 심을 접하도록 마찰력감소시켜 연비를 향사시키고, 태핏의 내구성을 향상시킬 수 있도록 하는 것이다.In the present invention, in order to solve the problems as described above, by pressing the semi-melted aluminum alloy and partially immersed in the porous ceramic located in the cavity (cavity), by reducing the frictional force to contact the tappet body and the seam to improve fuel economy, This is to improve the durability of the tappet.
