Description
본 발명은 판스프링 제조방법에 관한 것으로, 특히 금형판의 외주면에 복합재질을 감아 그 인장력을 이용하여 탄성력을 얻을 수 있게 함으로써, 탄성계수의 세기를 임의로 조절할 수 있는 판스프링 제조방법에 관한 것이다.The present invention relates to a method for producing a leaf spring, and more particularly, to a method of manufacturing a leaf spring that can arbitrarily adjust the strength of the elastic modulus by winding a composite material on the outer peripheral surface of the mold plate to obtain an elastic force using the tensile force.
일반적으로 판스프링은 소정의 두께를 갖는 판체 형상이 하나 또는 그 이상이 서로 겹쳐져서 반타원 형태로 구배지게 하여 휨 작용을 이용해 탄성력을 얻게 되며, 자동차의 차체와 차축 사이에 부착되어 완충역할을 하는데 많이 이용된다.In general, leaf springs have a plate thickness having a predetermined thickness, and one or more of them overlap each other to be gradient in a semi-elliptic shape to obtain elastic force using a bending action. It is used a lot.
이러한 판스프링은, 첨부도면 1에서 보는 바와 같이, 얇은 판체 형태로 제조된 금형판(10)을 탄성력의 세기를 고려하여 여러 장이 겹쳐진 상태로 단조가공을 통한 소성변형을 유도하여 제조하게 된다.Such a plate spring, as shown in the accompanying drawing 1, is produced by inducing plastic deformation through the forging process in a state in which several sheets are overlapped in consideration of the strength of the elastic plate in the form of a thin plate body.
그러나, 기존의 제조방법으로 탄성계수가 큰 판스프링을 제조하기 위해서는 많은 수의 얇은 복합재료를 적층시켜서 제조해야 하기 때문에, 탄성스프링의 자중이 많이 나가게 되고, 또한 이 탄성스프링이 외부에 장시간 동안 노출되면 내구성이 떨어지게 되어, 이에 대한 개선이 필요하게 되었다.However, in order to manufacture a plate spring having a large modulus of elasticity by using a conventional manufacturing method, a large number of thin composite materials must be laminated and manufactured, so that the self-weight of the elastic spring is increased, and the elastic spring is exposed to the outside for a long time. If the durability is lowered, there is a need for improvement.
본 발명은 상기와 같은 점을 감안하여 안출한 것으로, 판스프링의 형상과 유사한 형태로 제조된 금형판의 외주면에 여러개의 롤러에 감겨진 내구성이 강한 복합재료를 한꺼번에 적층가능하도록 감으면서 그 장력의 세기를 임의로 조절하여, 복합재료가 완전히 굳은 다음 금형판으로부터 빼내어 판스프링을 제조함으로써, 판스프링의 무게를 경량화 할 수 있을 뿐만 아니라 이 탄성스프링이 갖는 탄성계수를 임의로 쉽게 제조할 수 있는 자동차용 판스프링의 제조방법을 제공하는데 그 목적이 있다.The present invention has been made in view of the above-mentioned, the tension of the tension while winding the composite material, which is wound around a plurality of rollers on the outer circumferential surface of the mold plate manufactured in the form similar to the shape of the leaf springs at once By arbitrarily adjusting the strength, the composite material is completely hardened and then removed from the mold plate to manufacture a leaf spring, which not only reduces the weight of the leaf spring but also makes it easy to arbitrarily easily produce the elastic modulus of the elastic spring. It is an object of the present invention to provide a method for manufacturing a spring.

이를 첨부도면을 참조하여 보다 상세하게 설명하면 다음과 같다.This will be described in more detail with reference to the accompanying drawings.
첨부도면 2는 본 발명에 따른 판스프링의 제조방법을 나타내는 개략도로서, 도면부호 10은 금형판을 나타낸다.2 is a schematic view showing a method for producing a leaf spring according to the present invention, wherein 10 is a mold plate.
본 발명은 상기 금형판(10)의 외주면에 복합재료(20)가 소정의 장력을 가지도록 감아 여러겹으로 적층하여서, 무게가 가벼우면서도 복합재료(20)를 감으면서 결정된 장력의 세길에 따라 판스프링의 탄성계수를 임의로 조절가능하도록 한 것이다.According to the present invention, the composite material 20 is wound on the outer circumferential surface of the mold plate 10 so as to have a predetermined tension, and laminated in multiple layers. The plate is formed according to the length of tension determined while winding the composite material 20 while being light in weight. The elastic modulus of the spring is arbitrarily adjustable.
이러한 판스프링의 제조과정은 먼저, 사용하고자 하는 곳에 설치되는 판스프링이 갖는 탄성력을 계산하여 그 세기에 맞는 금형판(10)을 제작하게 된다.이때, 상기 금형판(10)은 여기에 감겨지는 복합재료(20)의 두께를 고려하여 그 두께를 결정하게 된다.The manufacturing process of such a leaf spring, first, to calculate the elastic force of the leaf spring installed in the intended place to produce a mold plate 10 according to the strength. In this case, the mold plate 10 is wound here The thickness of the composite material 20 is determined in consideration of the thickness thereof.
이때, 상기 금형판(10)은 길이방향의 양측 테두리부를 안쪽으로 소정의 곡률을 가지도록 설치면(11)을 절개성형하여, 이 금형판(10)에 복합재료(20)가 감겨짐에 따라 그 두께만큼 폭 길이가 늘어나지 않게 막아 주는 것이 바람직하다.At this time, the mold plate 10 is formed by cutting the mounting surface 11 so as to have a predetermined curvature inwardly on both side edge portions in the longitudinal direction, as the composite material 20 is wound around the mold plate 10 It is preferable to prevent the width length from extending by the thickness.
이어, 상기 금형판(10)을 작업대에 설치하여 회전가능하도록 설치하는 동시에 이 금형판(10)을 이 작업대의 롤러에 장력조절이 가능하도록 설치하게 된다.Subsequently, the mold plate 10 is installed on the workbench so as to be rotatable, and the mold plate 10 is installed on the roller of the workbench to adjust the tension.
즉, 상기 작업대는 금형판(10)을 계속 회전시킬 수 있도록 롤러가 구비되어 있으며 그 윗쪽에는 상기 복합재료(20)가 감겨진 상태에서 동시에 풀릴 수 있도록 설치가능한 여러개의 롤러(30)가 구비되어 있으며, 상기 금형판(10)과 롤러(30) 사이에는 이 금형판(10)이 회전함에 따라 복합재료(20)의 장력을 조절할 수 있도록 장력조절수단(40)과 상기 복합재료(20)가 금형판(10)에 부착이 잘되도록 부착제를 발라주는 장치로 이루어진 것이다.That is, the workbench is provided with a roller to continue to rotate the mold plate 10, the upper side is provided with a plurality of rollers 30 that can be installed to be released at the same time in the state in which the composite material 20 is wound The tension control means 40 and the composite material 20 are provided between the mold plate 10 and the roller 30 so that the tension of the composite material 20 can be adjusted as the mold plate 10 rotates. The mold plate 10 is made of a device for applying the adhesive so that the adhesion well.
따라서, 상기 복합재료(20)는 길이방향으로 감겨진 상태에서 상기 각 롤러(30)에 하나씩 필요한 갯수 만큼 설치되는 동시에 서로 겹쳐진 상태로 장력조절수단(40)을 경유하여 금형판(10)에 감겨지게 되며, 이때 상기 금형판(10)과 장력조절수단(40) 사이에서 부착제가 칠하여지게 되는 것이다.Therefore, the composite material 20 is installed on the rollers 30 one by one as many as necessary in the state wound in the longitudinal direction and is wound on the mold plate 10 via the tension adjusting means 40 in a state where they overlap each other. In this case, the adhesive is applied between the mold plate 10 and the tension control means 40.
또한, 상기 복합재료(20)는 카본섬유를 강화재로 하는 공강도· 고탄성의 경량 구조재(CFRP)를 이용하여, 탄성스프링의 무게를 최소화 하면서 외부에 노출된 경우에도 내식성과 진동감쇠성 등을 높일 수 있게 하는 것이 바람직하다.In addition, the composite material 20 increases the corrosion resistance and vibration attenuation resistance even when exposed to the outside while minimizing the weight of the elastic spring by using a carbon steel as a reinforcing material, a high-strength lightweight elastic structural material (CFRP). It is desirable to be able to.
이와 같이 복합재료(20)가 감겨질 수 있도록 준비된 상태에서 상기 금형판(10)을 회전시키면서 장력조절수단(40)을 이용하여 원하는 탄성계수를 가지도록 복합재료(20)를 잡아 당겨 감아 주게 된다.As described above, the composite material 20 is pulled and wound to have a desired elastic modulus by using the tension adjusting means 40 while rotating the mold plate 10 while the composite material 20 is prepared to be wound. .
마지막으로, 이렇게 감겨진 복합재료(20)가 충분히 경화될 때까지 두었다가 이 금형판(10)으로부터 경화된 복합재료(20)를 탈거하여 판스프링을 제조하게 되며, 이 개구된 양측에는 각각 미도시된 스틸제로 이루어진 설치브라켓 등을 끼워 마무리 공정을 마치게 되는 것이다.Finally, the coiled composite material 20 is left until it is sufficiently cured, and then the cured composite material 20 is removed from the mold plate 10 to manufacture a leaf spring. Finishing process is completed by inserting a mounting bracket made of steel.
이와 같이 이루어진 판스프링은 상기 각 설치브라켓을 이용하여 차량의 후륜 등과 같이 판스프링을 필요로 하는 부위에 설치하게 된다.The leaf spring made in this way is installed in a portion that requires the leaf spring, such as the rear wheel of the vehicle using the respective mounting bracket.
이상에서 본 바와 같이 본 발명은 소정의 두께를 갖는 금형판의 외주면에 여러겹이 겹쳐진 복합재료를 일정한 장력을 유지하도록 감아 충분히 경화시킨 후 그 양단에 각각 설치브라켓을 일체로 하여 판스프링을 제조함으로써, 판스프링의 제조 전에 미리 복합재료의 장력을 조절하여 탄성계수를 임의로 조절할 수 있을 뿐만 아니라 그 무게를 경량화 할 수 있는 장점이 있다.As can be seen from the above, the present invention is to sufficiently cure the composite material overlapping the outer circumferential surface of the mold plate having a predetermined thickness so as to maintain a constant tension, and then sufficiently harden and then manufacture the plate spring by integrally mounting brackets at both ends thereof. In addition, the elastic modulus can be arbitrarily adjusted by adjusting the tension of the composite material in advance before the manufacture of the leaf spring, and the weight can be reduced.
