제2도는 굽혀진 다듬질 안된 관을 도시하는 도면.2 shows a bent unfinished tube.

제3도 6 내지 제6도는 압력 작업대의 연속적인 과정을 도시하는 도면.3 to 6 show a continuous process of the pressure workbench.

Claims (5)

블랭크가 나선압연기에서 개방된 다듬질안된 관으로 압연되고 다듬질 안된 관이 그 전단부에 플랜지가 공을 통하여 직경의 감소부를 지니며 로드에 의해서 최종적으로 밀착되고 로드는 몇개의 연속적인 감소패스를 통하여 다듬질 안된 관속으로 주입되며 블랭크가 이러한 방법으로 연속적인 성형부에서 관속으로 열간압연되는 관 압력작업대 장치위에서 긴 관을 제조하는 방법에 있어서, 제1의 2개의 성형부에서 단면적의 감소부사용되며 이 감소부는 각각 연속적인 성형부에서 40 내지 60%이하로 단면이 감소되며 제1의 성형부에서 제3의 성형부로 다듬질 안된 관의 전단부가 이동할때 추력의 속도가 다듬질안된 관의 가속에 의해서 증가되는 것을 특징으로하는 관제조 방법.The blank is rolled into an unfinished tube open in a spiral mill, and the unfinished tube is finally pressed by the rod with a diameter reduction through the flange at its front end and the rod is trimmed through several successive reduction passes. A method of making a long tube on a tube pressure bench device in which a blank is injected into a tube and the blank is hot rolled into the tube in a continuous forming section in this way, in which the reduction of the cross-sectional area is used in the first two forming sections. The sections are reduced in cross section by less than 40 to 60% in each successive section and the rate of thrust is increased by the acceleration of the unfinished tube as the front end of the unfinished tube moves from the first section to the third section. Characterized in the manufacturing method. 제1의 성형부의 단면적의 감소가 2-5%이고 제2의 성형부의 단면적의 감소가 5-10%이며 가속상태가 제3의 패스속으로 다듬질안된 관의전단부의 감소부에서 종료되는 것을 특징으로하는 청구범위 1의 방법.The reduction in the cross-sectional area of the first molded part is 2-5%, the reduction in the cross-sectional area of the second molded part is 5-10% and the acceleration is terminated at the reduced part of the front end of the tube not trimmed into the third pass. The method of claim 1. 나선압연기, 플랜지가공장치 및 둥근단부를 지니나 모따지지않은 로드를 지니는 압력작업대로 구성되는 장치에 있어서, 관 압력작업대의 전방의 2개의 패스가 마무리되지 않은 관 단면에 대해 단면의 감소율이 6-12%로 설계되고 로드가 로드의 추력도가 2개의 전방의 압연스탠드를 통과할때 증가되게 하는 구동기어를 지니는 것을 특징으로하는 청구범위 1에 따른 관제조 장치.A device consisting of a spiral mill, a flanger, and a pressure bench with a rounded end but with a chamfered rod, wherein the rate of reduction of the cross section is 6-12 for a pipe section where the two paths in front of the pipe pressure platform are not finished. A control apparatus according to claim 1, characterized in that it is designed in% and has a drive gear which causes the load to increase when the thrust of the rod passes through two forward rolling stands. 제1의 패스에서는 단면감소가 약3%이고 제2의 패스에서는 약 8%이며 제1의 패스에서는 추력의 속도가 1-2m/s이고 제2의 패스에서는 2-3m/s이며 제3 및 계속되는 패스에서는 4-6m/s인것을 특징으로 하는 청구범위 3의 장치.Cross section reduction is about 3% in the first pass, about 8% in the second pass, thrust speed is 1-2 m / s in the first pass, 2-3 m / s in the second pass, The device of claim 3, wherein the pass is 4-6 m / s. 축상 압축장치가 마무리되지 않은 관을 플랜지시키고 원추상의 감소부의 내경을 감소시키며 원추각 22°내지 28°를 지니며 로드의 직각 사각형의 전방표면이 반경 8-12mm를 지니는 둥근단부를 지니며 다듬질안된 관의 내경과 로드직경사이의 차이가 로드직겨의 4-6인것을 특징으로하는 청구범위 3 또는 4의 장치.The axial compression device flanges the unfinished tube, reduces the inner diameter of the conical reduction section, trims it with rounded ends with a conical angle of 22 ° to 28 ° and the front surface of the right square of the rod with a radius of 8-12 mm. Apparatus according to claim 3 or 4, characterized in that the difference between the bore diameter of the tube and the rod diameter is 4-6 of the rod weave. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
