Description

시이즈히터의 제조방법Manufacturing method of sheath heater

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도 내지 제3도는 그 도면 순서대로 본 발명의 각기 다른 실시 차례를 예시하는 단면(제3도는 평면)개략도.1 to 3 are schematic cross-sectional views (FIG. 3 is a plan view) illustrating different embodiments of the present invention in the order of the drawings.

Claims (8)

앞 끝에 단자봉이 연결된 코일모양의 전열선을 금속제파이프에 집어 넣고 이 금속제파이프에 절연분말을 채운시이즈히터의 끝부분에 있는 트인곳에 이 끝부분둘레의 단자봉외주면 및 금속제파이프의 내주면에 내열성이고 또한 절연성인 윤활제를 도포한 후 관통공이 뚫린 비교적 경질의 캡을 끈부분 둘레의 단자봉외주면 및 금속제파이프의 내주면에 미끄럼접촉하게 끼워 넣고, 다음으로 이 끝부분을 그 외주면방향에서 중심축방향으로 면누름하여 캡의 직경을 균일하게 감축하므로써 그 캡의 반발응력을 면의 상태에서 끝부분둘레의 단자봉 외주면 및 금속제파이프의 내주면으로 균일하게 부가시켜 그 끝부분을 밀봉하는 시이즈히터의 제조방법.The coil-shaped heating wire with the terminal rod connected to the front end is inserted into the metal pipe, and the metal pipe is filled with insulation powder, and the heat resistance of the terminal rod outer circumference and the inner circumferential surface of the metal pipe at the end of the siege heater After applying the insulating lubricant, insert the relatively hard cap with the through hole in sliding contact with the outer circumferential surface of the terminal rod around the string and the inner circumferential surface of the metal pipe, and then press this end face in the direction of the center axis from the outer circumferential direction. By uniformly reducing the diameter of the cap so that the repulsive stress of the cap is uniformly added to the outer circumferential surface of the terminal rod and the inner circumferential surface of the metal pipe in the state of the face to seal the end. 제1항에 있어서,The method of claim 1, 윤활제가 실리콘오일인 시이즈히터의 제조방법Manufacturing method of sheath heater whose lubricant is silicone oil 제1항 또는 제2항에 있어서,The method according to claim 1 or 2, 캡이 불소고무제인 시이즈히터의 제조방법.The manufacturing method of the sheath heater whose cap is a fluororubber agent. 제1항 내지 제3항의 어느 하나의 항에 있어서,The method according to any one of claims 1 to 3, 면누름을 3분할 이상인 금형을 이용하여 캡의 횡단면 감소율 8%이상 되도록 실시하는 시이즈 히터의 제조방법.A method of manufacturing a siege heater, wherein the pressing of the cotton is carried out so that the rate of cross-sectional reduction of the cap is 8% or more using a mold having three or more divisions. 앞끝에 단자봉이 연결된 코일모양의 전열선을 금속제파이프에 집어 넣고 이 금속제파이프에 절연분말을 채운 시이즈히터의 끝부분에 있는 트인 곳에 이 끝부분 둘레의 단자봉외주면 및 금속제파이프의 내주면에 내열성이며 절연성인 윤활제를 도포한 후 관통공이 뚫린 비교적 경질의 캡을 끝부분 둘레의 단자봉외주면 및 금속제파이프의 내주면에 미끄럼접촉되도록 끼워 넣고, 다음으로 이 끝부분을 그 외주면방향에서 중심축방향으로 면누름하여 균일하게 직경을 감축하므로써 이 끝부분의 캡의 반발응력을 면의 상태에서 끝부분 둘레의 단자봉외주면 밑 금속제파이프의 내주면으로 균일하게 부가시키고 이와 함께 이 캡의 끼워 넣은 축의 일부를 끝이 넓어지는 모양으로 형성시켜서 끝부분을 밀봉하는 시이즈히터의 제조방법.The coil-shaped heating wire with the terminal rod connected to the front end is inserted into the metal pipe, and the metal pipe is filled with insulating powder. After applying phosphorus lubricant, insert the relatively hard cap with the through hole so as to be in sliding contact with the outer circumferential surface of the terminal rod around the end and the inner circumferential surface of the metal pipe, and then press the end face in the direction of the center axis from the outer circumferential direction. By uniformly reducing the diameter, the repulsive stress of the cap of this end portion is equally added to the inner circumference of the metal pipe under the outer circumference of the terminal rod in the state of the face in the face state, and the part of the capped shaft of the cap is widened. Method for producing a siege heater to form a shape to seal the end. 제5항에 있어서,The method of claim 5, 윤활제가 실리콘 오일인 시이즈히터의 제조방법.A method for producing a siege heater, wherein the lubricant is silicone oil. 제5항 또는 제6항에 있어서,The method according to claim 5 or 6, 캡이 불소그무인 시이즈히터의 제조방법.The manufacturing method of the siege heater whose cap is fluorine-free. 면누름을 3분할 이상인 금형을 이용하여 캡의 횡단면 감소율 8%이상 되도록 실시하는 시이즈히터의 제조방법.A method for producing a siege heater, wherein the pressing of the cotton is carried out so that the rate of cross section reduction of the cap is 8% or more using a mold having three or more divisions. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
