Description

원통형 저장조 구축용 주동링의 제조방법Manufacturing method of main ring for building cylindrical reservoir

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 종래의 주동링 제조방법에서 사용되는 장치의 개략설명도, 제2도는 본 발명 방법을 실시함에 적합한 제조실시 일실시예의 개략평면도, 제3도는 제2도의 안내환 및 수형로울부의 사시도, 제4도는 같은 안내환의 구동장치 부분의 사시도.1 is a schematic explanatory diagram of a device used in a conventional method for manufacturing a main ring, FIG. 2 is a schematic plan view of one embodiment of a manufacturing method suitable for carrying out the method of the present invention, FIG. 3 is a perspective view of the guide ring and male roll part of FIG. 4 is a perspective view of a drive unit part of the same guide ring.

Claims (1)

도면에 표시되고 본문에 상술한 바와 같이, 고일상에 권회된 대강을 권출하여 수형절곡성형기에 의하여 소정의 곡율을 갖는 만곡강대로 성형함과 동시에 이 성형만곡강대의 선단을 3개이상의 수형로울에 의하여 회전중심이 정해지는 회전자재한 안내환에 그 외측에서 진입시켜서 이 성형만곡강대를 상기 안내환의 외주에 권회하고 소정의 링둘레의 만곡강대를 얻은 부위에서 이 성형작업을 정지하여 소정의 링길이가 같아지는 위치에서 상기 만곡강대를 절단하고 그 절단단과 권출단을 용접접합함에 따라 소정 원주길이의 주동링을 순차 제조함을 특징으로 하는 원통형 저장조 구축용 주동링의 제조방법.As shown in the drawings and described above in the text, the coil wound around a high-day coil is unwound to be molded into a curved steel sheet having a predetermined curvature by a male bending machine, and the ends of the curved steel sheet are formed on three or more male rollers. The guide ring, which is the center of rotation, is determined from the outside of the guide ring by winding it on the outer circumference of the guide ring and stopping the molding operation at the part where the curved band of the predetermined ring is obtained. And cutting the curved steel strip at the same position and welding the cut end and the unwind end in order to sequentially manufacture a main ring having a predetermined circumferential length. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
