본 발명은 밸브 태핏 본체와 심(Shim)과의 접합을 양호하게 하여 엔진의 성능 및 연비를 향상시키고자 할 알루비늄 밸브 태핏(Tappet) 제조 방법에 관한 것이다.The present invention relates to a method for producing an aluminium valve tappet to improve the performance and fuel efficiency of the engine by making the junction of the valve tappet body and the shim good.
종래의 밸브 태핏은 제1도에서와 같이, 알루미늄 합금으로 이루어진 본체(1)의 상측 일부를 특수강 심(Shim)(2)을 압입방식을 이용하여 인서트(Insert)하여 형성시키게 된다.Conventional valve tappets are formed by inserting a special steel shim 2 using a press-in method in the upper part of the body 1 made of an aluminum alloy as shown in FIG.
이와같은 종래 밸브 태핏의 제조방법에 있어서는 압입방식을 이용하여 특수강 심(2)을 인서트 시키게 되므로서, 본체(1)와의 접합이 안정되게 이루어지지 않아 엔진의 성능이 저하되거나, 연비가 나빠지는 문제점이 발생하게 된다.In the conventional method of manufacturing a valve tappet, since the special steel core 2 is inserted by using a press-fit method, the joint with the main body 1 is not made stable and the performance of the engine is lowered or fuel economy is worsened. This will occur.
본 발명에서는 상기에서와 같은 문제점을 해결하기 위하여 반용융상태의 알루미늄 합금을 가압하여 캐비티(Cavity)내에 위치하고 있는 다공질 세라믹에 부분 용침 시키므로서, 태핏 본체와 심을 접하도록 하여 마찰력감소시켜 연비를 향상시키고, 태핏의 내구성을 향상시키고자 한 것이다.In the present invention, in order to solve the problems as described above by pressing the semi-melted aluminum alloy to partially infiltrate the porous ceramic located in the cavity (cavity), by contacting the tappet body and the seam to reduce the friction force to improve fuel economy To improve the durability of the tappets.
상기와 같은 목적을 실행하기 위한 본 발명 알루미늄 밸브 태핏(Tappet) 제조 방법의 실행수순을 설명하면 다음과 같다.Referring to the execution procedure of the present invention aluminum valve tappet manufacturing method for performing the above object as follows.
반 용융상태의 알루미늄 합금을 가압하는 단계와, 캐비티 내에 위치하고 있는 다공질 세라믹에 부분 용침시키는 단계와, 태핏 본체와 심을 접합하는 단계로 이루어지게 되는 바, 도면 제2도는 본 발명 알루미늄 밸브 태핏(Tappet) 제조 방법에 의한 밸브 태핏의 구조를 보인 도면으로서, 제2도를 참조하여 본 발명 제조 방법의 실행단계에 따른 작용을 설명하면 다음과 같다.Pressurizing the semi-melted aluminum alloy, partially infiltrating the porous ceramic located in the cavity, and joining the tappet body and the shim. FIG. 2 is a view illustrating the invention aluminum valve tappet. As a view showing the structure of the valve tappet according to the manufacturing method, the operation according to the execution step of the manufacturing method of the present invention with reference to FIG.
도면에 도시된 'A'부에 압력을 가하여 반용융 상태의 알루미늄 합금(11)에 가압을 하게 된다.Pressure is applied to the aluminum alloy 11 in the semi-molten state by applying pressure to the 'A' portion shown in the figure.
상기와 같이 반용융상태의 알루미늄 합금(11)에 가압을 하여 캐비티(12) 내에 위치하고 있는 다공질 세라믹(13)에 부부 용침시키게 된다.As described above, the semi-molten aluminum alloy 11 is pressurized to couple and infiltrate the porous ceramic 13 located in the cavity 12.
상기와 같이 다공질 세라믹(13)에 부분용침되어지므로서, 태핏 본체와 심이 접합을 하게 되는 것이다. 이때, 반용융상태의 알루미늄 합금(11)의 제조는 고주파 유도방식으로 하게 된다.As it is partially immersed in the porous ceramic 13 as described above, the tappet body and the shim are bonded. At this time, the manufacturing of the semi-molten aluminum alloy 11 is made by the high frequency induction method.
이와 같이 하므로서, 연속적인 본체와 심과의 접합상태를 얻을 수 있게 되어 태핏의 내구성 및 품질이 향상된다.In this way, the continuous state of the main body and the seam can be obtained, thereby improving the durability and quality of the tappet.
또한, 반용융 상태의 알루미늄 합금(11)에 가압을 하여, 다공질 세라믹(13)의 부분용침이 가능하게 되므로서, 내마모성 및 마찰손실을 감소시켜 엔진의 성능 및 연비를 향상시키게 된다.In addition, by pressurizing the aluminum alloy 11 in the semi-molten state, the partial infiltration of the porous ceramic 13 is possible, thereby reducing wear resistance and friction loss, thereby improving engine performance and fuel economy.
