여기서, 상기 수축억제부(11)는 압출된 골판시트(1)의 냉각과정에 있어 격벽의 수축을 억제하여 형을 유지할 수 있게 하는 진공포밍기(50)의 양측에 삽입되는 진공포밍기삽입부와, 상기 진공포밍기삽입부와 결합부(12) 사이에서 골판시트(1)의 두께 수축에 따라 안내할 수 있게 흡입홈(13)의 상하측에 가이드(13b)를 형성한 가이드부로 구성되는 것이다.Here, the shrinkage suppressing portion 11 is inserted into the vacuum forming machine inserting portions inserted into both sides of the vacuum forming machine 50 to suppress the shrinkage of the partition wall in the cooling process of the extruded corrugated sheet (1) And a guide part having a guide 13b formed on the upper and lower sides of the suction groove 13 so as to be guided according to the thickness shrinkage of the corrugated sheet 1 between the vacuum forming machine insertion part and the coupling part 12. will be.
한편, 상기 흡입홈(13)에 형성된 흡입공(13a)의 지름은 골판시트(1)의 양측을 훼손시키지 않게 0.8mm 이하로 형성하고, 그 간격은 5mm 이내로 실시하는 것이 바람직하다.On the other hand, the diameter of the suction hole (13a) formed in the suction groove 13 is formed to 0.8mm or less so as not to damage both sides of the corrugated sheet (1), the interval is preferably carried out within 5mm.
이하, 본 고안의 작용에 대하여 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.
상기한 바와 같이 수축억제부(11)와 결합부(12)로 구성된 본 고안의 결합부(12)를 압출다이스(30)에 결착되어 있는 결합구(20)에 슬라이딩 결합하여 설치한다.As described above, the coupling part 12 of the present invention including the shrinkage inhibiting part 11 and the coupling part 12 is installed by slidingly coupling to the coupling hole 20 that is attached to the extrusion die 30.
이상과 같이 본 고안이 설치된 상태에서 골판시트(1)의 압출을 시작하면 압출다이스(30)에서 압출된 골판시트(1)가 압출다이스(30)의 전면 상하부에 설치된 에어나이프(40)에서 공급되는 에어에 의하여 냉각되며 수축되게 되는데, 이때 양측에 구비된 본 고안의 흡입홈(13)의 흡입공(13a)에서 작용되는 진공에 의하여 골판시트(1)의 양측이 상기 흡입홈(13)에 흡착되며 압출되게되어 압출이 완료된 상태의 골판시트(1)폭과 압출시의 폭이 동일하게 유지되어 제품의 손실이 최소화되는 것이다.When the extrusion of the corrugated sheet 1 is started in the state where the present invention is installed as described above, the corrugated sheet 1 extruded from the extrusion die 30 is supplied from the air knife 40 installed at the front and top of the extrusion die 30. It is cooled by the air is to be contracted, in which case both sides of the corrugated sheet (1) by the vacuum acting in the suction hole (13a) of the suction groove 13 of the present invention provided on both sides to the suction groove (13) It is adsorbed and extruded so that the width of the corrugated sheet 1 in the state where extrusion is completed and the width during extrusion are kept the same to minimize the loss of the product.
따라서, 본 고안은 압출다이스에서 압출되는 골판시트의 양측에서 진공압에 의하여 폭수축을 억제하며 압출시키므로서 폭수축이 최소화되어 폭수축으로 인한 제품의 손실이 최소화되고 양측단의 수축부 절단과 같은 후가공을 실시하지 않아도 되어 작업성이 향상되며, 압출된 골판시트의 격벽과 격벽의 폭이 균일하게 유지되므로 제품의 질이 향상되는 매우 유용한 것이다.Therefore, the present invention suppresses the width shrinkage by vacuum pressure on both sides of the corrugated sheet extruded from the extrusion die, thereby minimizing the width shrinkage, thereby minimizing the loss of the product due to the width shrinkage and cutting the shrinkage of both ends. It is not necessary to perform post-processing, and workability is improved, and the width of the partition walls and the partition walls of the extruded corrugated sheet is uniformly maintained, so that the quality of the product is very useful.
