    • An arrangement for securing and easily releasing a mandrel from a mandrel rod upon their advancement and return movements during the piercing operation of a seamless tube. Between the mandrel and rod is an intermediate piece having one or more openings for receiving a hook with a nose extending into an opening of the mandrel. The hook is biased into position by a spring mounted around its one end and at its other end beneath a nose is a tapered surface for contacting a corresponding surface of the mandrel to pivot the hook away from the interior of the mandrel to release the mandrel from the intermediate piece and mandrel rod.
    • 一种用于在无缝管的穿孔操作期间在心轴杆的前进和后退移动时固定和容易地从心轴杆释放心轴的装置。 在心轴和杆之间是具有一个或多个开口的中间件,用于容纳具有延伸到心轴的开口中的鼻部的钩。 通过围绕其一端安装的弹簧将钩偏压到位,并且其另一端在鼻下方是锥形表面,用于接触心轴的对应表面以使钩远离心轴的内部枢转以将心轴从 中间件和芯棒。

    • The present invention provides a seamless tube piercing/rolling plug and a seamless tube producing method in which piercing/rolling is performed with an inclined rotary piercing mill while the seamless tube piercing/rolling plug is used as a piercing tool. The seamless tube piercing/rolling plug is used while a front part and a rear part of the split plug are held as an integral plug, at least the front part is made of low alloy steel, and oxide films are formed on surfaces of the front part and rear part. The present invention also provides a seamless tube piercing/rolling apparatus and a seamless tube producing method in which the front part and/or rear part is replaceable in a tube making process line using the seamless tube piercing/rolling apparatus. In the seamless tube piercing/rolling apparatus, the front part and rear part are held as the integral plug, the front part and/or rear part is removably mounted, a mandrel bar holding the plug goes through the rear part, and the mandrel bar is coupled with the front part. It is preferable that a thickness of the oxide film formed in the front part be set to 200 μm or more while the oxide film formed in the front part is thicker than the oxide film formed in the rear part. Even if a hard working material is pierced/rolled, a seam defect and inside surface defects are eliminated, and excellent life-time of plug and excellent plug cost per production quantity can be achieved.
    • 本发明提供了一种无缝管穿孔/滚压塞和无缝管制造方法,其中在使用无缝管穿孔/滚塞作为穿孔工具的同时,用倾斜的旋转穿孔机进行穿孔/轧制。 使用无缝管穿刺/滚压塞,而分离塞的前部和后部被保持为整体塞,至少前部由低合金钢制成,并且氧化膜形成在前表面 部分和后部。 本发明还提供了一种无缝管穿孔/轧制装置和无缝管制造方法,其中使用无缝管穿孔机可以在管制造线中替换前部和/或后部。 在无缝管穿刺/轧制装置中,前部和后部被保持为一体式塞子,前部和/或后部可拆卸地安装,保持插头的芯棒穿过后部,并且芯棒 与前部相结合。 优选的是,形成在前部的氧化膜的厚度设定为200μm以上,而在前部形成的氧化膜比形成在后部的氧化膜厚。 即使硬质材料被刺穿/轧制,也可以消除接缝缺陷和内表面缺陷,并且可以实现优异的插头寿命和优异的插头成本。
