Abstract

PURPOSE: Clamp ring structure for fixing a bladder is provided to extend the durability of the bladder by preventing the bladder from being folded upon contracting the bladder and to avoid damage to a tire. CONSTITUTION: One pair of clamp rings is installed on upper and lower parts of a boom. A clamp end of a bladder is inserted between the clamp rings. An outer circumferential face(20) of the clamp ring(2) contacting an inner face of the bladder is formed in a polygonal shape. A pressure source in the bladder is removed to withdraw a tire from a vulcanizing die so that the bladder is contracted. In this process, an inner circumferential face of the bladder is supported on the outer circumferential face of the clamp ring. At the same time, the outer circumferential face of the bladder is contracted into the polygonal shape equally to a shape of the outer circumferential face of the clamp ring. Thus, a protruding event generated as the outer circumference of the bladder is rapidly folded is prevented.

Description

브라더 고정용 클램프 링 구조{Cure Bladder Clamp Ring Apparatus}Clamp Ring Structure for Brother Fixing {Cure Bladder Clamp Ring Apparatus}

본 발명은 타이어 가류용 브라더를 고정시키는 클램프 링에 관한 것으로서, 더욱 상세하게는 가류금형으로부터 가류가 완료된 타이어를 인출시키기 위하여 브라더를 수축시키는 과정에서 브라더가 심한 각도로 찌그러지는 것을 방지함으로써, 브라더의 내구 수명을 연장시키고 인출되는 타이어의 손상을 방지할 수 있게 하는 브라더 고정용 클램프 링 구조에 관한 것이다.The present invention relates to a clamp ring for fixing a tire vulcanizing brother, and more particularly, by preventing the brother from crushing at a severe angle in the process of shrinking the brother to pull out the vulcanized tire from the vulcanization mold, The present invention relates to a clamp fixing structure for fixing a brother that can extend the service life and prevent damage to a tire that is drawn out.

일반적으로 브라더라 함은 자동차용 타이어의 가류공정시 타이어의 내부에 설치되어 고온 고압에 의해 팽창되면서 타이어를 가류금형에 압착시키는 고무풍선이다.In general, a brother is a rubber balloon that is installed inside a tire during a vulcanization process of an automobile tire and expands by high temperature and high pressure to compress the tire onto a vulcanization mold.

이와 같은 브라더는 타이어의 가류동작시 팽창과 수축 동작을 반복 수행하는 것으로서 강한 내구성이 요구된다.Such a brother is required to have a strong durability by repeating the expansion and contraction operation during the vulcanization operation of the tire.

첨부된 도면 도 1 은 일반적인 브라더 고정 상태를 도시한 단면도이다.1 is a cross-sectional view showing a general brother fixed state.

도 1 에 도시되는 바와 같이, 승하강 동작되는 붐(4)의 상하부에 각각 한 쌍의 크램프링(2)(3)이 설치되고, 상기 각각의 클램프링(2)(3) 사이에 브라더(1)의 클램프단(11)이 삽입 결합되는 구조를 이룬다.As shown in FIG. 1, a pair of clamping rings 2 and 3 are respectively provided on upper and lower portions of the boom 4 that is operated in a lowering direction, and a brother (B) between the clamping rings 2 and 3 is provided. The clamp end 11 of 1) forms a structure that is inserted and coupled.

종래에 있어서의 클램프 링구조는 첨부된 도면 도 2 및 도 3 에 도시되는 바와 같이, 브라더(1)의 내주면과 접촉되는 클램프링(2)의 외주연(20)이 원형으로 형성되어 있다.In the conventional clamp ring structure, as shown in FIGS. 2 and 3, the outer circumferential edge 20 of the clamp ring 2 in contact with the inner circumferential surface of the brother 1 is formed in a circular shape.

이와 같은 종래의 클램프 링(2)은 가류가 완료된 타이어를 금형으로부터 인출시키기 위하여 붐(4)이 상승 동작을 하게 되고 이와 동시에 브라더(1)의 내부에 존재하던 압력 원이 제거되면서 수축 동작을 이루게 된다.Such a conventional clamp ring (2) is a boom (4) to the lifting operation to take out the vulcanized tire from the mold and at the same time to remove the pressure source existing inside the brother (1) to achieve a shrinkage operation do.

이때 수축되는 브라더(1)는 원형의 클램프 링(2)의 외주연(20)에 지지되면서 접혀지게 되며, 클램프단(11)으로부터 가까운 부분은 원형을 유지하지만 브라더(1)의 중앙 부위에 가까울수록 진공상태의 영향에 의해 첨부된 도면 도 4 에 도시되는 바와 같이, 브라더(1) 원주상의 접혀지는 부분이 심하게 돌출 되는 돌출부(10)를 형성시키게 된다.At this time, the contracted brother 1 is folded while being supported by the outer circumference 20 of the circular clamp ring 2, and the portion close to the clamp end 11 maintains the circular shape but is close to the center of the brother 1. As shown in FIG. 4 attached by the influence of the vacuum state, the circumferentially folded portion of the brother 1 forms a protrusion 10 protruding severely.

이와 같이 브라더(1)의 수축동작시 마다 브라더 외주연에 심한 접힘이 반복하여 발생하게 되면 브라더(1)의 표면에 뜯김이나 크랙이 발생되어 내구 수명을 단축시키게 됨은 물론 이러한 돌출 부위(10)가 인출되는 타이어의 내면 즉, 비드부 내측과 접촉되어 손상시키는 문제점이 있는 것이다.As described above, if a serious folding occurs repeatedly on the outer circumference of the brother every time the contracting operation of the brother 1 occurs, the surface of the brother 1 may be torn or cracked to shorten the endurance life, as well as such a protruding portion 10 There is a problem of contacting and damaging the inner surface of the tire to be drawn out, that is, the inside of the bead portion.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명은 브라더의 수축동작시 브라더의 접힘 현상을 방지하여 브라더의 내구 수명을 연장시키고, 인출되는 타이어가 손상되는 것을 방지할 수 있게 하는 브라더 고정용 클램프 링 구조를 제공함에 그 목적이 있다.The present invention has been made to solve the above-described problems, the present invention is to prevent the folding of the brother during the contraction operation of the brother to extend the endurance life of the brother, it is possible to prevent damage to the tire pulled out The purpose is to provide a clamping ring structure for fixing.

본 발명은 상기와 같은 목적을 달성하기 위해서 다음과 같이 구성된다. 즉, 본 발명은 승하강 동작되는 붐의 상하부에 한 쌍의 크램프링이 각각 설치되고, 상기 각각의 클램프링 사이에 브라더의 크램프단이 삽입 결합되는 것에 있어서, 브라더의 내부면과 접촉되는 클램프링의 외주면에 다수의 평면을 등간격으로 형성시켜 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. That is, according to the present invention, a pair of clamping rings are respectively installed at upper and lower portions of the boom which is operated in a lowering direction, and clamping ends of the clamps are contacted with the inner surfaces of the brothers. It is characterized by being formed by forming a plurality of planes at equal intervals on the outer peripheral surface of the.
