It relates to an iron pallet formed with a pressing joint portion on the upper plate and the lower plate, characterized in that.

이를 상세히 서술하면 아래와 같다. 지게차의 포크가 파렛트에 끼워지게 하기 위하여 항상 대부분의 철재파렛트는 상판과 하판과 이들 사이에 개재되는 중간판으로 구성되며, 또 다른 형태는 상기 중간판을 세분하여 상부지지판, 하부지지판, 중간지지구로 구성하고 이것을 체결하며, 완성된 중간판을 상기의 상판과 하판과의 사이에 다시 체결하는 구성이다.Detailed description thereof is as follows. Most steel pallets always consist of an upper plate and a lower plate and an intermediate plate interposed therebetween, so that the fork of the forklift truck is fitted to the pallet, and another form divides the intermediate plate into an upper support plate, a lower support plate, and an intermediate support. It constitutes and fastens this, and it is a structure which refastens the completed intermediate board between said upper board and lower board.

여기서 상기 상판, 하판등은 직사각형 형상으로서, 표면을 평면으로 하거나, 혹은 강도의 증가를 위하여 표면이 구형파 모양으로 오목부와 볼록부가 교호로 형성된 직사각형의 패널형상이다.Here, the upper plate, the lower plate, etc. have a rectangular shape, and have a flat surface, or a rectangular panel shape in which the concave portion and the convex portion are alternately formed in a square wave shape in order to increase the strength.

이는 필요에 의하여 선택적으로 철판을 관용의 롤포밍기에서 제작하여 사용할 수 있다.This can optionally be used to produce a steel sheet in a conventional roll forming machine as needed.

롤포밍기에서의 철판을 상기와 같은 여러종류의 형태로 제단하는 것은 이미 많은 특허문헌에 주지기술로 공지되어 있는 바, 이의 자세한 설명은 생략한다.The cutting of the iron plate in the roll forming machine into various types as described above is well known in many patent documents, and a detailed description thereof is omitted.

본 고안은 상기와 같이 제작된 평판 또는 오목부와 볼록부가 교호로 형성된 철판을 사용하여 파렛트를 제작함에 있어서, 프레싱죠인트부를 형성하여 긴밀하게상판,하판, 중간판 등을 체결함에 있는 바, 본 고안의 요지로 인정되는 프레싱죠인트에 관하여 설명하여 보면, 먼저 상하형의 금형을 제작하되 하부금형은 ''형태의 홈이 형성되게 제작하고, 상부금형은 상기 홈과 결합되게 수직돌기를 형성하고, 상기 중간지지구에는 체결편을 형성하되, 상기 체결편은 상기 상판등과의 접합을 위하여 중간지지구에 설치된 것으로서, 중간지지구의 양단부에 설치되되, 각단부에서 사방으로 설치되어 어느 방향에서도 상판, 하판 등과 결합이 가능하게 형성되어 있다. 여기에서 중간지지구는 필요에 따라서 여러개 설치할 수 있다.The present invention is to produce a pressing joint portion in close contact with the plate or the concave portion and the convex steel plate formed as described above, to form a pressing joint portion to fasten the upper plate, lower plate, intermediate plate, etc., the present invention To explain the pressing joint, which is considered to be the gist of the mold, first, the upper and lower molds should be manufactured. 'The groove is formed to form, the upper mold is formed with a vertical projection to be combined with the groove, the intermediate support to form a fastening piece, the fastening piece is connected to the upper plate and the like to the intermediate support As installed, it is installed at both ends of the intermediate support, it is installed in each direction from each end is formed to be coupled to the upper plate, the lower plate and the like in any direction. Here, the intermediate supports can be installed as many as needed.

따라서, 예를 들어 상판과 상기 중간지지구를 결합할 경우에 있어서는 먼저, 프레스에서 파렛트의 상기 상판의 일단부와 상기 중간지지구의 단부에 형성된 체결편을 상기 하부금형의 상부에 포개어 놓고 상기 상부금형을 가압하게 되면 상부금형에 형성된 수직돌기가 압력에 의하여 상기 상판의 일단부와 중간지지구의 체결편을 순차적으로 가압하여 형상을 상기 하부금형의 홈의 형상에 맞게 변형하며 홈내부에 체결되며, 홈의 형상이 약간은 상부에서 하부로 비스듬하게 그 단면이 확장되게 형성된 연유로 상기 수직돌기와 홈사이에 공간부가 형성되고, 이 공간에 상기 수직돌기에 의하여 밀려난 상기 상판의 일단부와 체결편의 일부가 채워지게 되며, 동시에 상기 상판과 중간지지구의 체결편은 공고하게 기계적으로 결합되게 된다. 앞서 기술한 공정이 종료된 후 상기 상부금형은 상승하고 아울러 공고하게 체결된 상기 상판과 중간지지구의 체결편은 상기 상부금형에 의하여 상승하거나, 타출기에 의하여 하부금형 밖으로 타출되게 된다.Therefore, in the case of joining the upper plate and the intermediate support, for example, first, the fastening piece formed at one end of the upper plate of the pallet and the end of the intermediate support in the press is stacked on the upper portion of the lower mold and the upper mold is formed. When pressing the vertical projection formed in the upper mold by pressing the fastening piece of the upper end and the middle support in sequence by the pressure to deform the shape to fit the shape of the groove of the lower mold is fastened in the groove, The space between the vertical projection and the groove is formed by the reason that the cross-section is slightly obliquely extending from the top to the bottom of the one end of the upper plate and the fastening piece pushed by the vertical projection in this space At the same time the fastener of the upper plate and the intermediate support is firmly mechanically coupled. After the above-described process is completed, the upper mold is raised and the fastening pieces of the upper plate and the intermediate support firmly fastened are lifted by the upper mold or out of the lower mold by the machine.

상기의 과정 및 기술적 구성은 하판과 중간지지구와의 결합시도 동일하며,더욱 상세하게는 중간판을 상부지지판과 하부지지판과 중간지지구로 세분하여 제작할 경우에 있어서도. 앞서의 원리로 상판과 상부지지판과 중간지지구의 체결편을 동시에 프레스에서 압입하거나, 하판과 하부지지판과 중간지지구의 체결편을 동시에 프레스에서 압입하는 것이 가능하다.The above process and technical configuration is the same when combining the lower plate and the intermediate support, and more specifically, even when the intermediate plate is manufactured by subdividing the upper support plate, the lower support plate and the intermediate support. According to the above principle, it is possible to press-fit the fastening pieces of the upper plate and the upper support plate and the intermediate support at the same time in the press, or press-fit the fastening pieces of the lower plate and the lower support plate and the intermediate support at the same time.

따라서, 본고안은 파렛트의 상판과 하판과 그 사이에 개재되는 중간지지구의 결합을 프레싱죠인트부를 형성하여 체결함으로써, 그 체결부위가 강도 및 기계적 성질이 뛰어날 뿐더러 철재파렛트 제작에 있어서 전자동화가 가능하며, 인건비가 절약되어 기존의 목재 및 철재파렛트와 비교하여 경쟁력이 월등히 낫게 되는 이점이 있다.Therefore, the present proposal is to form a pressing joint portion of the upper plate and the lower plate of the pallet and the intermediate support interposed therebetween to form a pressing joint portion, the fastening portion is excellent in strength and mechanical properties, and fully automated in the production of steel pallets. As a result, labor costs are reduced, and the competitiveness is much better than that of the existing wood and steel pallets.
