열융착용 툴{TOOL FOR THERMAL BONDING}Heat Fusion Tool {TOOL FOR THERMAL BONDING}

본 고안은 열융착 장치에 사용되는 열융착용 툴에 관한 것으로, 더욱 상세하게는 열융착팁에 히터하우징이 나사결합되는 열융착용 툴에 관한 것이다.The present invention relates to a tool for heat fusion used in a heat welding apparatus, and more particularly, to a tool for heat welding in which a heater housing is screwed to a heat welding tip.

자동차에서 주로 트림류의 부품들은 소정 형상의 플라스틱 판재를 서로 겹쳐 열융착 가공하여 제작하는 경우가 많은데, 이는 한쪽 판재에 형성된 홀을 통해 돌출된 다른 한쪽 판재의 돌기를 열융착용 툴을 사용하여 가열 및 가압함으로써 돌기의 상단을 리벳 머리 형태로 가공하여 두 플라스틱 판재를 연결하는 것이다.In automobiles, trim parts are often manufactured by overlapping plastic sheets of a predetermined shape with each other and heat-sealing them. By pressing, the top of the projection is machined into a rivet head to connect the two plastic plates.

이때, 종래의 열융착용 툴(10)의 경우 도 1에 도시된 바와 같이, 중공을 가진 히터 하우징(20) 내부에 히터 케이블(30)이 연결된 히터(40)가 삽입 수용되어 전기적으로 가열되고, 히터 하우징(20)의 끝단에 열융착팁(50)이 삽입 결합된다.At this time, in the case of the conventional heat fusion tool 10, as shown in Figure 1, the heater 40 connected to the heater cable 30 is inserted into the heater housing 20 having a hollow is electrically received, The heat welding tip 50 is inserted into and coupled to the end of the heater housing 20.

그런데 대부분의 열융착 장치에서, 플라스틱 융착물의 양호한 융착형상을 만 들기 위해서는 열융착팁의 온도를 유지 관리하는 것이 매우 중요하다.By the way, in most heat fusion apparatuses, it is very important to maintain the temperature of the heat fusion tip in order to create a good fusion shape of the plastic fusion.

즉, 열융착팁은 히터에 의해 가열되고 압축공기로 냉각되는 싸이클(cycle)이 반복되므로, 열융착팁의 열전도 상태는 융착형상의 품질과 장치의 싸이클 타임(cycle time)에 영향을 미치게 된다.That is, since the cycle of the heat welding tip is heated by the heater and cooled by the compressed air, the heat conduction state of the heat welding tip affects the quality of the welding shape and the cycle time of the device.

따라서, 설비의 전력소비량 감소 및 사이클 타임 감소, 품질 향상을 위해, 열융착팁의 열전도율을 높이고, 히터의 사용온도를 낮추어 온도편차를 줄일 필요가 있다.Therefore, in order to reduce the power consumption of the facility, reduce the cycle time, and improve the quality, it is necessary to increase the thermal conductivity of the heat welding tip and reduce the temperature deviation by lowering the use temperature of the heater.
