도 1 및 도 2에 도시된 바와 같이, 종래 프레스 금형(1)의 하형(3)에는 패널을 성형하는 로터리 캠축(5)이 회전 가능하도록 결합되고, 이 로터리 캠축(5)은 하우징 스틸(7)에 의하여 고정된다.As shown in FIGS. 1 and 2, a rotary camshaft 5 for forming a panel is rotatably coupled to the lower mold 3 of the conventional press die 1, and the rotary camshaft 5 is connected to the housing steel 7. It is fixed by).

상기 구성을 갖는 종래 로터리 캠축이 결합된 프레스 금형의 작동을 설명하면, 미도시된 상형의 캠 슬라이더가 하향운동을 하면, 하형에 결합된 로터리 캠축(5)은 원운동을 하여 정위치에 세팅됨으로써 패널의 제품 형상을 완성한다. 상기 완성된 패널의 취출은 로터리 캠축(5)의 리턴 원운동에 의하여 취출된다.Referring to the operation of the press mold combined with the conventional rotary cam shaft having the above configuration, when the upper cam slider (not shown) moves downward, the rotary cam shaft (5) coupled to the lower mold is set to the correct position by the circular motion Complete the product shape of the panel. The finished panel is taken out by the return circular motion of the rotary cam shaft 5.

그러나, 상기 로터리 캠축의 회전에 의한 패널의 성형이 지속되면, 하형(3)과 로터리 캠축(5)과의 마찰면에는 마찰열이 발생된다. 이에 따라 하형(3)과 로터리 캠축(5)은 마찰열에 의한 접착이 발생되어 패널 성형의 중단이 빈번하게 발생되는 문제점이 있다.However, if the molding of the panel by the rotation of the rotary cam shaft continues, frictional heat is generated on the friction surface between the lower mold 3 and the rotary cam shaft 5. Accordingly, the lower mold 3 and the rotary cam shaft 5 have a problem in that adhesion due to frictional heat is generated, so that the panel molding is frequently interrupted.

본 발명은 상기 전술한 바와 같은 문제점들을 해결하기 위해 창출된 것으로서, 프레스 금형의 하형에 구비된 로터리 캠축과 하형과의 마찰을 저감할 수 있는 프레스 금형을 제공하는데 그 목적이 있다.The present invention has been made to solve the problems as described above, and an object thereof is to provide a press mold capable of reducing friction between the rotary cam shaft and the lower mold provided in the lower mold of the press mold.

상기 목적을 달성하기 위한 본 발명의 프레스 금형은, 하형에 장착된 로터리캠축으로서 패널을 성형하는 프레스 금형에 있어서, 상기 하형과 마찰발생 부위의 상기 로터리 캠축에는 다수개의 마찰 저감부재가 결합되는 것을 특징으로 한다.The press mold of the present invention for achieving the above object is a press mold for forming a panel as a rotary cam shaft mounted on a lower mold, characterized in that a plurality of friction reducing members are coupled to the rotary cam shaft of the lower mold and the friction generating portion. It is done.

본 발명에 있어서, 상기 마찰 저감부재의 재질은 카본(CARBON)인 것을 특징으로 한다.In the present invention, the friction reducing member is characterized in that the carbon (CARBON).

이하 본 발명의 바람직한 실시예에 따른 프레스 금형을 첨부된 도면을 참조하여 상세히 설명한다. 그러나 본 발명은 이하에서 개시되는 실시예에 한정되는 것이 아니라 서로 다른 다양한 형태로 구현될 것이며, 단지 본 실시예는 본 발명의 개시가 완전하도록 하며, 통상의 지식을 가진자에게 발명의 범주를 완전하게 알려주기 위해 제공되는 것이다.Hereinafter, a press mold according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the present embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you.

도 3은 본 발명의 바람직한 실시예에 따른 프레스 금형을 개략적으로 도시한 측단면도이고, 도 4는 본 발명의 로터리 캠축을 개략적으로 도시한 사시도이다.Figure 3 is a side cross-sectional view schematically showing a press die according to a preferred embodiment of the present invention, Figure 4 is a perspective view schematically showing a rotary camshaft of the present invention.

도 3 및 도 4에 도시된 바와 같이, 본 발명에 따른 프레스 금형(100)의 하형(10)에는 로터리 캠축(20)이 장착되며, 상기 하형(10)과 마찰되는 로터리 캠축(20)에는 마찰 저감부재(30)가 결합된다.3 and 4, the rotary cam shaft 20 is mounted on the lower mold 10 of the press die 100 according to the present invention, and the rotary cam shaft 20, which is rubbed with the lower mold 10, is rubbed. Reduction member 30 is coupled.

상기 로터리 캠축(20)은 미도시된 상형에 결합된 캠 슬라이더가 하강되면 하형(10)과 마찰됨과 함께 원운동하여 소정의 패널을 성형한다. 이러한 상기 로터리 캠축(20)을 이용한 소정의 패널의 성형은 공지된 것으로서 그 자세한 작동 설명은 생략한다. 상기 로터리 캠축(20)이 하형(10)과 마찰되는 부분에는 다수개의 마찰 저감부재(30)가 결합된다.When the cam slider coupled to the upper mold (not shown) is lowered, the rotary cam shaft 20 is rubbed with the lower mold 10 and circularly moves to form a predetermined panel. The molding of a predetermined panel using the rotary camshaft 20 is known, and detailed operation thereof will be omitted. A plurality of friction reducing members 30 are coupled to the portion where the rotary cam shaft 20 is rubbed with the lower mold 10.

상기 마찰 저감부재(30)는 카본(CARBON) 재질로 이루어지며, 상기 하형(10)과 마찰되는 로터리 캠축(20)의 외측에 다수개로 결합된다. 이에 따라, 상기 로터리 캠축(20)은 그 회전시에 마찰 저감부재(30)의 건조마찰에 의한 윤활 작용으로서 회전이 원활하게 된다.The friction reducing member 30 is made of a carbon (CARBON) material, it is coupled to the outside of the rotary cam shaft 20, which is rubbed with the lower mold (10). Accordingly, the rotary cam shaft 20 is smoothly rotated as a lubrication action by dry friction of the friction reducing member 30 at the time of its rotation.

구체적으로 설명하면, 로터리 캠축(20)의 패널 성형을 위하여 회전되면, 로터리 캠축(20)에 설치된 마찰 저감부재(30)는 하형(10)과 마찰됨에 의하여 건조마찰 즉, 카본 재질의 마찰 저감부재(30)로부터 분말이 발생하여 하형(10)과 로터리 캠축(20)이 분말의 매개작용에 의하여 마찰 저감되어 그 회전이 용이하게 된다.In detail, when the rotary cam shaft 20 is rotated to form the panel, the friction reducing member 30 installed on the rotary cam shaft 20 is rubbed with the lower mold 10 so as to dry friction, that is, the friction reducing member made of carbon. Powder is generated from 30, and the lower mold | type 10 and the rotary camshaft 20 are reduced friction by the mediating action of powder, and its rotation becomes easy.

상기의 구성을 갖는 본 발명에 따른 프레스 금형의 작용을 설명한다.The operation of the press die according to the present invention having the above configuration will be described.

본 발명에 따른 프레스 금형의 로터리 캠축(20)과 하형(10)과의 마찰되는 면에 카본 재질로 이루어지는 다수개의 마찰 저감부재(30)를 결합한다.A plurality of friction reducing members 30 made of a carbon material are coupled to the surfaces of the press die according to the present invention in which the rotary cam shaft 20 and the lower mold 10 are rubbed.

그러면 상기 로터리 캠축(20)은 카본재질의 마찰 저감부재(30)의 분말을 통한 건조 윤활 특성에 의하여 마찰열을 줄임으로써, 로터리 캠축(20)이 하형(10)과 열접합됨에 의하여 작업진행이 불가능해짐을 예방한다.Then, the rotary camshaft 20 reduces frictional heat due to the dry lubrication characteristic through the powder of the friction reducing member 30 made of carbon material, and thus, the rotary camshaft 20 is thermally bonded to the lower mold 10, thereby making it impossible to proceed with work. Prevent dissolution

상기와 같은 본 발명에 따른 프레스 금형은 다음과 같은 효과를 갖는다.The press mold according to the present invention as described above has the following effects.

하형과 마찰되는 로터리 캠축의 마찰면에 카본 재질로 이루어지는 다수개의 마찰 저감부재를 결합함으로써, 로터리 캠축의 회전시에 발생되는 마찰력을 저감하여 작업진행을 원활하게 할 수 있다.By combining a plurality of friction reducing members made of carbon material with the friction surface of the rotary cam shaft to be rubbed with the lower die, it is possible to reduce the friction force generated when the rotary cam shaft is rotated to smoothly proceed the work.

이상, 본 발명을 도면에 도시된 실시예를 참조하여 설명하였다. 그러나, 본 발명은 이에 한정되지 않고 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명과 균등한 범위에 속하는 다양한 변형예 또는 다른 실시예가 가능하다. 따라서, 본 발명의 진정한 보호범위는 이어지는 특허청구범위에 의해 정해져야 할 것이다.The present invention has been described above with reference to the embodiments shown in the drawings. However, the present invention is not limited thereto, and various modifications or other embodiments falling within the scope equivalent to the present invention are possible by those skilled in the art. Therefore, the true scope of protection of the present invention should be defined by the following claims.
