Abstract

In the weight manufacturing method, a part of weight element is cut from a sheet plate in sizes of 1/2, 1/3 or 1/4 disc plate; the steel plates are piled up for the cut edges of the disc to cross one another, and is vertically welded to form into a layered product; and the welded product are coated by rubber.

The steel sheet is manufactured by removing the circular steel sheets and laminating them to the required thickness and welding them to each other by rubber coating.

본 발명의 주된 특징은 중량체를 주물로 제작하지 않고 짜투리 강판을 이용하기 때문에 제작 단가가 저렴하다는 데 있다.The main feature of the present invention is that the production cost is low because the steel plate is used without producing the weight as a casting.

본 발명의 다른 특징은 강판을 적층하는 방법과 이들을 용접하는 방법에 있는데 즉,

Figure kpo00013
원형 강판을 서로 엇갈리게 적층하고 상하에서 압력을 가한 상태로 용접하는 것이다.Another feature of the present invention lies in a method of laminating steel sheets and a method of welding them, that is,

본 발명을 도면과 공정 순서에 따라서 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the drawings and process steps.

(1) 제1도에서와 같이 짜투리 강판에서 중량체의 일부를 구성하는 반원형,

Figure kpo00014

이때 짜투리 강판의 모양과 크기에 따라서 반원형이나

Figure kpo00016
원형 및
Figure kpo00017
원형등을 결정하여 절단하면 된다.In this case, depending on the shape and size of the steel sheet,
Figure kpo00016
Round and
Figure kpo00017
The round lamp is determined and cut.

(2) 제2도에서와 같이 각층 마다 서로 방향을 바꾸어 엇갈리게 적층한다.(2) As in FIG. 2, the layers are alternately stacked with each other changing directions.

(3) 제3도에서와 같이 상하에서 압력(P)을 가한 상태로 적층체(W)를 수직 방향으로 용접(10)한다. 용접(W)은 수직 방향으로 줄용접(W)을 여러개소 실시하면 된다.(3) As in FIG. 3, the laminate W is welded 10 in the vertical direction with the pressure P applied up and down. What is necessary is just to perform several welding of the welding W in the vertical direction.

(4) 제4도에서와 같이 용접된 적층체(S)에 가류하기전의 고무(R)를 부착하여 금형속에서 가열 가압하므로써 고무코팅(R)하여 완성한다.(4) The rubber (R) before vulcanization is attached to the welded laminate (S) as shown in FIG. 4, and the rubber coating (R) is completed by heating and pressing in the mold.

이와같은 과정에 의하여 중량체를 제작하면 짜투리 강판을 이용하여 중량체를 구성하므로 폐자재를 이용하게 되어 제작원가가 매우 저렴하고, 짜투리 강판의 크기 및 모양에 따라서 각종 모양을 선택하여 절단하여도 이들을 서로 선택적으로 적절히 조합하여 조립적층하므로써 동일한 모양의 중량체를 완성시킬 수가 있는 장점이 있다.When the weight body is manufactured by such a process, the weight body is formed by using the steel sheet, so that the waste material is used, and the manufacturing cost is very low, and even if various shapes are selected and cut according to the size and shape of the steel sheet, There is an advantage in that the weight body of the same shape can be completed by appropriately combining with each other selectively and laminated.
