Abstract

The method prevents the melting heat from getting tansmitted to a non- melting part of the water flow tube when melting the edges of the sheets to manufacture the water flow tube. The meathod comprises the steps of: leaving a space between the upper/lower coolers(2,2') and the upper/lower heaters(1,1'); narrowing the adhesion area between the coolers(2,2') and the heaters(1,1') to reduce the heat transmission area.

본 발명은 관수튜브 융착제조시 열변형을 방지하기 위한 열변형 방지방법에 관한 것으로, 특히 융착부를 가열시켜 융착시킬때 융착부의 열이 냉각부의 비융착 부위에 전달되지 않도록 방지해 주기위한 열변형 방지방법에 관한 것이다.The present invention relates to a thermal deformation preventing method for preventing thermal deformation during the manufacturing of the watering tube fusion welding, in particular, to prevent the heat deformation to prevent the heat of the fusion portion is transferred to the non-fusion region of the cooling portion when the fusion portion is heated and fused. It is about a method.

종래의 관수튜브 융착제조시 열변형을 방지해주는 열변형 방지방법을 제공해 주지 못하고 있기 때문에 테프론 벨트 사이에 인취된 쉬트의 양쪽 가장자리(융착부위)를 녹여 붙이기 위해 융착부 속에 있는 히타로서 융착부를 가열시키게 되는데, 이때 쉬트의 비융착부위가 열을 받으면 완제품이 찌그러들어 융착부의 열이 냉각부의 비융각부위에 전달됨과 동시에 냉각부에 열변형이 발생하여 비융착부위가 열을 받게되므로 단열효과를 높이지 못하는 문제점이 있었다.Since it is not possible to provide a thermal deformation prevention method that prevents thermal deformation in the conventional manufacturing of the watering tube fusion welding, it is necessary to heat the welding portion as a heater in the welding portion to melt and attach both edges of the sheet drawn between the Teflon belts. At this time, when the non-fused part of the sheet receives heat, the finished product is crushed, and the heat of the fused part is transferred to the non-melted part of the cooling part, and at the same time, heat deformation occurs in the cooling part, so that the non-fused part receives heat. There was a problem.

본 발명은 관수튜브 융착제조시 열변형을 방지해 주기위한 열변형 방지방법을 제공하는 것이다.The present invention is to provide a method for preventing heat deformation to prevent heat deformation during the fusion manufacturing of watering tube.

즉, 히타로서 융착부를 가열시켜 융착시킬때 가열되는 열(열변형)이 비융착부위에 전달되는 것을 방지해 주기 위한 본 발명은 융착부와 냉각부 사이에 S1, S2만큼 간격을 두어 고체 열전달을 방지시키거나, 또는 융착부와 냉각부 접합시 접합면적을 줄여 전열면적을 최소화하여 단열효과를 향상시킴으로서 융착부를 가열시켜 융착시킬때 가열되는 열이 비융착부위에 전달되지 않도록 하여 관수튜브 융착제조시 비융착부위에 전달되는 열변형을 방지시키도록한 것으로서, 이를 첨부도연에 의거하여 본 발명을 상세히 설명하면 다음과 같다.That is, the present invention to prevent the heat (heat deformation) is transmitted to the non-fusion region when the fusion portion is heated by fusion as a heater, the space between the fusion and the cooling portion by S 1 , S 2 by a solid To prevent heat transfer, or to minimize the heat transfer area by improving the insulation area by reducing the junction area when joining the fusion part and the cooling part, thereby heating the fusion part so that the heated heat is not transferred to the non-fusion part. In order to prevent the thermal deformation transmitted to the non-fusion region during manufacture, the present invention will be described in detail based on the accompanying drawings.

The upper and lower fusion parts 1 and 1 'and the upper and lower cooling parts 2 and 2' are spaced apart by S 1 and S 2 so as not to be delivered to the non-fusion part 8. will be.

이와 같이 구성된 본 발명의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above in detail.

먼저 상,하 테프론 인취벨트(6), (6') 사이에 인취된 상,하 쉬트(5), (5')의 양쪽 가장자리(융착부위)를 녹여 붙이기 위해 상,하 융착부(1), (1') 내부에 있는 상,하 히타 (3), (3')로 융착부(1), (1')를 가열시켜 융착시킨다.First, the upper and lower fusion portions (1) for melting and attaching both edges (fusion areas) of the upper and lower sheets 5 and 5 'taken between the upper and lower Teflon inlet belts 6 and 6'. And (1 ') the fusion unit (1) and (1') are heated and welded by the upper and lower heaters (3) and (3 ').

이때, 가열되는 열이 상,하 쉬트(5), (5')의 비융착부위(8)에 전달되어 비융착부위가 열을 받게되므로 완제품이 찌그러드는 등 열변형이 발생하게 되는데, 본 발명은 비융착부위(8)에 전달되는 열을 방지하기 위하여 상,하 냉각부(2), (2') 내부로 냉각수(4 ), (4')를 통과시켜 냉각부(2), (2')를 냉각시킴과 동시에 상,하 융착부(1), (1')와 상,하 냉각부(2), (2') 사이에 S1만큼 간격을 둠으로서 직접적인 열전달을 방지하게 된다.At this time, the heat to be heated is transferred to the non-fusion region 8 of the upper, lower sheets 5, 5 'and thus the non-fusion region receives heat, resulting in thermal deformation such as crushing of the finished product. In order to prevent the heat transferred to the non-fused portion 8, the cooling water 4, 4 'is passed through the upper and lower cooling parts 2 and 2' to the cooling parts 2, 2 Cooling ') and at the same time by the interval between the upper and lower fusion parts (1), (1') and the upper and lower cooling parts (2), (2 ') by S 1 to prevent direct heat transfer.

이와 동시에 상,하 융착부(1), (1')와 상,하 냉각부(2), (2') 사이의 접속부분에 S2만큼 간격을 둠으로서 융착부(1), (1')와 냉각부(2), (2') 접합시 그 접합면적을 줄여 주므로서 융착부(1), (1')가 가열시켜 융착시킬 때 상,하 융착부(1), (1')의 열(열변형)이 상,하 냉각부(2), (2')의 비융착부위(8)에 전달되는 것을 방지하게 되는 것이다.At the same time, the space between the upper and lower fusion portions 1 and 1 'and the upper and lower cooling portions 2 and 2' is spaced by S 2 to form the fusion portions 1 and 1 '. ) When the fusion zones 1 and 1 'are heated and welded, the upper and lower fusion zones 1 and 1' are reduced by reducing the joint area when joining the cooling unit 2 and 2 '. The heat (heat deformation) of the upper and lower cooling parts (2), will be prevented from being transferred to the non-fusion region (8) of (2 ').

이와 같이 본 발명은 융착부와 냉각부 사이에 S1, S2만큼 간격을 둠으로서 고체 열전달을 방지시킴과 동시에 융착부와 냉각부 접합시 접합면적을 줄여 전열면적을 최소화하여 단열효과를 향상시킴으로서 융착부를 가열시켜 융착시킬때 가열되는 열이 비융착부위에 전달되는 것을 방지해주는 효과가 있는 것이다.As described above, the present invention prevents solid heat transfer by spacing S 1 and S 2 between the welded part and the cooling part, and at the same time, reduces the junction area when joining the welded part and the cooling part, thereby minimizing the heat transfer area to improve the thermal insulation effect. When the fusion is heated to fusion, there is an effect of preventing the heat to be transferred to the non-fusion region.
