A seam welder using a heat roller to enable melt compression.

일반적으로 (매쉬)시임 용접기는 두께 또는 재질이 서로 다른 2장의 강판패널을 상호 오버랩시켜 상,하부 전극 롤러을 통하여 압괴 통전시킴으로 하나의 패널로 용접을 행하는 장치로서, 도 1에서 도시한 바와 같이, 종래에는 선행패널(101)과 후행패널(103)을 공급하여주는 컨베이어(105) 상에 이를 지지하도록 각각 선행 클램퍼(107)와 후행 클램퍼(109)가 구성되고, 상기 선행 및 후행 클램퍼(107,109) 사이에는 용접기 상,하부 본체(111,112)에 상,하부 전극 롤러(115,117)가 구성된다. In general, the (mesh) seam welder is a device that performs welding by one panel by overlapping two steel sheet panels having different thicknesses or materials, and crushing and energizing the upper and lower electrode rollers. The front clamper 107 and the trailing clamper 109 are respectively configured to support the front panel 101 and the rear panel 103 on the conveyor 105, and between the leading and trailing clampers 107 and 109. The upper and lower electrode rollers 115 and 117 are formed on the upper and lower main bodies 111 and 112 of the welder.

그리고 상기 상부 본체(111) 상에는 가압 실린더(113)를 장착하여 구성된다. And it is configured by mounting the pressure cylinder 113 on the upper body 111.

따라서 2장의 강판패널로 된 선,후행패널(101,103)이 컨베이어(105)를 통하여 각각 공급되어 오버랩되면, 상기 선행 및 후행 클램퍼(107,109)가 이를 각각 고정하게 되고, 이때 상기 용접기 상부 본체(111)를 전진시키면서, 상기 가압 실린더(113)를 작동시켜 상,하부 전극 롤러(115,117)가 상기 선행 및 후행패널(101,103)의 오버랩구간을 용접하게 된다. Therefore, when the front and rear panels 101 and 103 of two sheets of steel sheets are respectively supplied through the conveyor 105 and overlapped with each other, the leading and trailing clampers 107 and 109 fix them, respectively. While advancing, the pressure cylinder 113 is operated so that the upper and lower electrode rollers 115 and 117 weld the overlapping sections of the preceding and following panels 101 and 103.

이러한 전극 롤러(115,117)를 이용한 시임 용접은 선행 및 후행패널(101,103)의 오버랩구간을 가압하면서 전기저항에 의해 내부에 용접부(W)를 형성하여 용접하게 되는데, 이러한 전극 롤러(115,117)는, 도 2에서 도시한 바와 같이, 전원 공급부(119)로부터 각각의 회전축(121)의 일측을 통하여 전원을 공급받도록 구성된다.

도 3은 본 발명의 실시예에 따른 열 롤러를 이용한 시임 용접기의 부분 정면 도이고, 도 4는 본 발명의 실시예에 따른 열 롤러의 사용 상태도이다. 3 is a partial front view of a seam welder using a heat roller according to an embodiment of the present invention, and FIG. 4 is a state diagram of a heat roller according to an embodiment of the present invention.

본 발명의 실시예에 따른 열 롤러를 이용한 시임 용접기의 구성은 선행패널(1)과 후행패널(3)을 공급하여주는 컨베이어(5) 상에 이를 지지하도록 각각 선행 클램퍼(7)와 후행 클램퍼(9)가 각각 구성된다.The construction of the seam welding machine using the heat roller according to the embodiment of the present invention is to support the preceding clamper 7 and the trailing clamper (7) so as to support them on the conveyor 5 for supplying the preceding panel 1 and the trailing panel 3. 9) are respectively constructed.

상기 선행 및 후행 클램퍼(7,9) 사이에는 상기 양측 패널(1,3)의 상부면과 하부면에 각각 구름 접촉되도록 용접기 상,하부 본체(11,12)에 각각 상,하부 롤러(15,17)를 구성하며, 상부 본체(11) 상에는 가압 실린더(13)를 장착하여 구성된다. The upper and lower rollers 15, respectively, on the upper and lower main bodies 11 and 12 of the welder so as to be in contact with the upper and lower surfaces of the two panels 1 and 3, respectively, between the leading and trailing clampers 7 and 9. 17) and the pressurizing cylinder (13) is mounted on the upper main body (11).

여기서, 상기 상,하부 롤러(15,17) 각각의 양 외측면에 대응하여 상기 상,하부 본체(11,12) 내측에는 고주파 유도 가열기가 구성되는데, 상기 고주파 유도 가열기(21)는 고주파를 발진시키는 고주파 발진기(23)로부터 고주파신호를 수신하여 상기 상,하부 롤러(15,17)를 설정온도까지 가열하여 각각이 열에너지를 갖는 열 롤러로 작용하도록 구성된다. Here, a high frequency induction heater is formed inside the upper and lower bodies 11 and 12 to correspond to both outer surfaces of the upper and lower rollers 15 and 17, and the high frequency induction heater 21 oscillates a high frequency. It is configured to receive a high frequency signal from the high frequency oscillator 23 to heat the upper and lower rollers (15, 17) to a set temperature to act as a thermal roller each having thermal energy.

여기서, 상기 설정온도는 알루미늄의 용융점 온도인 약 660℃인 것이 바람직하며, 상기 상,하부 롤러(15,17)의 소재는 스틸재질로 하여 이루어지는 것이 바람직하다.Herein, the set temperature is preferably about 660 ° C., which is the melting point temperature of aluminum, and the upper and lower rollers 15 and 17 are preferably made of steel.

특히, 상기 상,하부 롤러(15,17)의 소재는 고온에서 내산화성, 내고온부식성 및 고온강도를 유지하는 내열 합금강으로 이루어지는 것이 바람직하다.In particular, the material of the upper and lower rollers 15 and 17 is preferably made of heat-resistant alloy steel that maintains oxidation resistance, high temperature corrosion resistance and high temperature strength at high temperatures.

따라서 상기한 바와 같은 구성을 갖는 열 롤러를 이용한 시임 용접기는 물리적 특성상 용융점이 약 660℃로 낮고, 열 전도율이 높은 복수의 알루미늄 패널을 그 용융점의 특성을 이용하여 고주파 유도가열에 의해 가열되는 열 롤러를 이용하 여 용융 압착시켜 용접하게 된다. Therefore, the seam welder using the heat roller having the above-described configuration has a low thermal melting point of about 660 ° C. in view of physical properties, and heat rollers which are heated by high frequency induction heating using a characteristic of the melting point. It is welded by melt compression using.

즉, 용융점이 낮은 알루미늄 패널로 된 선,후행패널(1,3)이 컨베이어(5)를 통하여 각각 공급되어 오버랩되면, 상기 선행 및 후행 클램퍼(7,9)가 이를 각각 고정하게 된다. That is, when the front and trailing panels 1 and 3 made of aluminum panels having a low melting point are respectively supplied through the conveyor 5 and overlapped, the preceding and trailing clampers 7 and 9 fix them.

이때, 고주파 발진기(23)에서는 고주파신호를 각각의 고주파 유도 가열기(21)로 출력하고, 이에 따라 상,하부 롤러(15,17)는 그 양측부에 대응하는 각각의 고주파 유도 가열기(21)에 의해 상기 알루미늄의 용융점 온도인 약 660℃까지 가열되어 열에너지를 포함하는 열 롤러로 작용할 수 있게 된다. At this time, the high frequency oscillator 23 outputs a high frequency signal to each of the high frequency induction heaters 21, so that the upper and lower rollers 15 and 17 are applied to the respective high frequency induction heaters 21 corresponding to both sides thereof. By heating to about 660 ℃ the melting point temperature of the aluminum it is possible to act as a thermal roller containing thermal energy.

이와 같이, 상,하부 롤러(15,17)가 가열된 후에는 상기 가압 실린더(13)를 작동시켜 상부 본체(11)를 하강시키면, 상,하부 롤러(15,17)는 상기 선행 및 후행패널(101,103)의 오버랩구간을 고열로 용융시키면서 압착하여 연속적으로 용접하게 된다. As such, after the upper and lower rollers 15 and 17 are heated, when the upper cylinder 11 is lowered by operating the pressurizing cylinder 13, the upper and lower rollers 15 and 17 are the preceding and following panels. The overlapping sections of (101, 103) are pressed while being melted with high heat and continuously welded.

이에 따라, 본 발명의 열 롤러를 이용한 시임 용접기는 스틸재 강판패널보다 용융점이 현저히 낮고, 열전도율이 높은 알루미늄 패널의 경우에는 그 소재의 낮은 용융점 특성을 이용하여 용접부(W)가 미려하게 용접되는 것이다. Accordingly, the seam welder using the heat roller of the present invention has a significantly lower melting point than steel sheet panels, and in the case of an aluminum panel having a high thermal conductivity, the weld portion W is beautifully welded using the low melting point characteristics of the material. .
