Description

대형 기계케이스의 무용접 제작방법{METHOD OF PREPARING LARGE-SIZED MACHINE CASE WITHOUT WELDING}Non-welding method of large machine case {METHOD OF PREPARING LARGE-SIZED MACHINE CASE WITHOUT WELDING}

본 발명은 대형기계를 보호하는 케이스의 제작방법 및 그 장치에 관한 것으로, 레이저 절단기에 전개상태의 크기와 각종 구멍등을 입력한 후 원판을 절단한 다음 절단된 판체를 절곡기를 이용하여 졸곡한 후 결합하여 리벳팅작업으로 간단하게 조립할 수 있도록 하는데 그 목적이 있는 것이다.The present invention relates to a method for manufacturing a case and a device for protecting a large machine, and after inputting the size and various holes of the developed state into the laser cutting machine, cutting the disc and then bending the cut plate using a bending machine. The purpose is to allow easy assembly by riveting by combining.

일반적으로 금속으로 된 크고 작은 케이스는 현대 우리사회에서 널리 사용되고 있는 바, 종래에 사용되어온 케이스를 살펴보면 소형의 케이스는 구조가 간단하여 제작이 간편하기 때문에 용접하여 제작하기가 쉬운 장점이 있으며, 또한 케이스가 대량으로 사용될 경우 원판을 절단하는 절단기에 원판을 절단할 수 있는 금형을 부착하여 한번에 대량으로 절단한 다음 절곡기에서 절곡하고 이 상태에서 각각의 연결부에 드릴을 이용하여 체결공을 형성한 다음 리벳을 이용하여 고정하는 방법이 사용되고 있으나 원단만을 한번에 절단하여 대량으로 제작하고 나머지 공정은 일일이 사람의 손으로 하여야 함으로서 공정이 복잡하고 힘들며 불필요한 인건비의 지출과 작업시간을 낭비하게 되는 문제점이 있었다.In general, large and small cases made of metal are widely used in modern Korean society. Looking at the cases used in the past, the small case has an advantage of being easy to manufacture because of its simple structure and easy manufacturing. If a large quantity is used, attach a mold that can cut the disc to a cutter that cuts the disc, cut it in bulk at a time, then bend it in the bending machine, and in this state, form a fastening hole using a drill at each connection part, and then rivet. The fixing method is used, but only a single piece of fabric is cut at a time, and the rest of the process has to be done by human hands. Therefore, the process is complicated, difficult, and wastes unnecessary labor expenses and working time.

그러나 상기와 같은 방법은 케이스를 대단위로 제작할 경우 금형을 제작하여 원판을 절단할 수는 있으나, 케이스의 수량이 소형일 경우 고가의 금형을 제작할 수가 없기 때문에 사람이 일일이 원판에 치수선을 표기하고 그 선을 따라 절단하였다.However, in the above method, if the case is manufactured in large units, it is possible to cut the original plate by making a mold. However, if the number of cases is small, a person cannot mark the dimension line on the original plate and the line is drawn. Cut along.

상기와 같이 사람이 일일이 치수선을 표기하고 절단하여야 하기 때문에 정확도가 떨어지게 되는 단점이 있으며, 원판을 절단한 다음 다시 치수선을 따라 절곡시키고, 이 상태에서 각각의 접촉면을 용접하여 고정하였기 때문에 제조공정이 복잡하고 힘들며, 이로 인하여 정확한 제품을 만들기가 힘든 문제점이 있었다.As described above, there is a disadvantage in that accuracy is reduced because a person must mark and cut a dimension line one by one, and the manufacturing process is complicated because the original plate is cut and then bent along the dimension line, and each contact surface is welded and fixed in this state. It was difficult, and because of this, it was difficult to make a correct product.

본 발명은 상기와 같은 문제점을 해결하기 위하여 발명한 것으로서, 레이저절단기를 이용하여 원판의 절단과 함께 리벳팅할 자리에 체결공을 함께 가공할 수 있도록 함으로서, 제품의 크기에 상관없이 단시간에 제품을 생산할 수 있도록 한 것으로서, 작업공정을 줄여 제작단가를 절감시킬 수 있도록 한 것으로서, 이하 본 발명을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been invented to solve the above problems, by using a laser cutting machine to be able to process the fastening hole together in the place to be riveted with the cutting of the disc, regardless of the size of the product in a short time In order to produce as, to reduce the production process to reduce the manufacturing cost, the present invention will be described in detail by the accompanying drawings as follows.

1단계로 제작하고자 하는 케이스를 전개시킨 상태로 설계한 다음, 2단계로 레이저 절단기를 작동시키는 컴퓨터에 설계도를 입력시키고, 3단계로 레이저절단기를 이용하여 원단을 절단한 다음 4단계로 절단된 원단을 절곡기를 이용하여 절곡시키고, 5단계로 절첩된 자재를 연결한 다음 연결부위에 리벳팅작업을 하여 고정하여서 된 것이다.After designing the case to be developed in the first step, input the design into the computer that operates the laser cutter in the second step, cut the fabric using the laser cutter in the third step, and then cut the fabric in the fourth step. After bending by using a bending machine, the material is folded in five steps, and then fixed by connecting the riveting work.

즉 설계작업에서부터 원판을 절단할때 각 지주(2)와 상하판체(3) 또는 도어나 측면판에 절단할 부위와 결합시 리벳팅할 부위와 홀(4)을 설정하여 절단기에서 미리 홀(4)을 가공하여 작업하는 방법으로서, 원판 절단후 절곡기를 이용하여 절곡작업만 한 후 리벳(1)을 결합하여 리벳팅작업만 하면 되는 것이다.That is, when cutting the original plate from the design work, each part (2) and the upper and lower plate bodies (3) or the part to be riveted when combined with the part to be cut in the door or side plate, and the hole (4) to be riveted in advance in the cutter As a method of working by), only the bending work using a bending machine after cutting the disk and then only riveting by combining the rivets (1).

상기와 같이 된 본 발명의 작업방법을 설명하면 다음과 같다.Referring to the working method of the present invention as described above is as follows.

제작하고자 하는 기계케이스를 설계할때 각 부품을 절곡하여 조립한 다음 리벳팅하여 고정하고자 하는 부분에 홀을 설계하고 이 설계도를 레이저절단기 작동용 컴퓨터에 입력시킨 상태에서 레이저 절단기에 원판을 공급한 다음 절단기를 작동시킨다.When designing the machine case to be manufactured, bend and assemble each part, design the hole in the part to be fixed by riveting, supply the original plate to the laser cutting machine while inputting the design into the computer for operating the laser cutting machine. Start the cutter.

상기와 같이 레이저 절단기를 작동시키면 입력되어 있는 설계도에 따라 원판을 절단함과 동시에 리벳팅할 부분에 홀을 일체로 가공하게 되는 것이다.When operating the laser cutting machine as described above is to cut the disc according to the input design and at the same time to integrally process the hole in the portion to be riveted.

상기와 같이 레이저에 의하여 원판을 절단함과 동시에 크고 작은 원을 레이저로 가공하기 때문에 별도로 홀을 가공하는 공정을 줄일 수가 있는 것이다.As described above, since the original plate is cut by the laser and the large and small circles are processed by the laser, the process of separately processing the hole can be reduced.

상기와 같은 상태에서 절단된 판재를 절곡기로 이송하여 절곡시켜 각각의 부품을 형성한 다음 각 부품을 조립한 상태에서 고정부위에 형성되어 있는 홀에 리벳을 이용하여 고정하면 되는 것이다.The plate material cut in the above state is transferred to a bending machine to be bent to form each part, and then fixed by using a rivet in a hole formed in the fixing part in the state of assembling each part.

이상과 같이 본 발명은 레이저절단기를 이용하여 원판의 절단과 함께 리벳팅할 자리에 체결공을 함께 가공할 수 있도록 함으로서, 제품의 크기에 상관없이 단시간에 제품을 생산할 수 있도록 한 것으로서, 작업공정을 줄여 제작단가를 절감시킬 수 있도록 한 것으로서, 구조가 간단하여 제작이 용이하고 원단을 절단할 때 고정용 홀을 같이 형성하기 때문에 제작공정을 줄임으로서 작업시간을 단축하고 제작단가를 절감시킬 수가 있으며, 또한 기계케이스의 크기에 상관없이 저렴한 가격으로 단시간내에 제작할 수가 있는 유용한 발명인 것이다.As described above, the present invention allows the fastening hole to be processed together with the cutting of the original plate by using a laser cutter, so that the product can be produced in a short time regardless of the size of the product. In order to reduce the production cost, it is easy to manufacture due to its simple structure, and the fixing holes are formed together when cutting the fabric, thus reducing the production process and reducing the production time. In addition, regardless of the size of the machine case is a useful invention that can be produced in a short time at a low price.
