摘要： 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.

摘要： A device for automatically feeding plugs to the end of the mandrel in the gap between the rolling rolls of a plug mill in the rolling of a seamless steel tube, comprising a rotary device disposed adjacent the defined path of the seamless steel tube in passing through the rolling rolls of the plug mill such that on rotation of said rotary device a plug is discharged from a pocket therein to an inlet guide member forming part of said defined path which has one end thereof adjacent the gap between the rolling rolls, the plug being supported by the inlet guide member during its passage in the end of the seamless steel tube into the gap, the inlet guide member being adapted to provide a gap therein to allow the plug after completion of the rolling of the tube and before stripping of the tube to fall away from the mandrel in the gap between the rolling rolls and be returned to a lower unoccupied pocket in the rotary device.

摘要： A tube making mill setup includes an induction heater for a billet, with means to transfer the heated billet directly to a piercing machine. The piercing machine includes main driving and gripping rolls on skewed axes and which drive the billet onto a piercing point. Upper and lower control rolls have axes parallel to the direction of billet drive through the machine. Internal cooling of the control rolls and the piercing point is provided by circulating cooling water through them. The piercing point is at the distal end of a mandrel which is swingable through an arc to place the formed tube on a take-away carriage.

摘要： In a rolling mill having a perforating head supported on a bar which is rotatable and longitudinally displaceable, the bar is supported on a carriage by way of a gripper fixed to the carriage and engaging a recess in the bar with sufficient radial play to allow rotation of the bar. The recess also affords axial clearance so that the rolling reaction on the perforating head displaces the rear end of the bar into abutment with a planar end contact face of a rotating bearing. The abutment of the end of the bar against the contact face allows the bar to be ejected laterally without previous axial disengagement of the bar from the bearing.

摘要： The disclosure relates to method and apparatus for the operation of a plug mill, in the production of seamless tubes. Provisions are made for maintaining a circulating supply of plug and mandrel assemblies such that, after a tubular shell from a piercing mill has been given a first pass through the plug mill, the entire combination of the plug and mandrel assembly, and the just-processed shell, are transferred bodily into alignment with the axis of a second stage mill. The shell is then advanced in the same direction through a second mill stand, over a second plug, while simultaneously being stripped from the first mandrel. By enabling the shell to be passed through the second plug mill pass, without the requirement of an intermediate operation of stripping the shell from the first stage mandrel, significant time economies are realized. With conventional plug mill equipment and techniques, the plug mill represents a bottleneck in the sequence of operations involved in the production of seamless tubing. In contrast, with the method and apparatus of the invention, the plug mill can easily operate at a greater rate of speed than the piercing mill supplying tubular shells to it. This is accomplished with only a modest increase in investment in mill equipment.
摘要翻译：本公开涉及在无缝管的生产中用于塞式磨机的操作的方法和装置。规定了保持塞子和心轴组件的循环供应，使得在来自穿孔机的管状壳体已经被首次通过塞子磨机之后，塞子和心轴组件的整个组合以及刚加工的壳体被转移到与第二级磨机的轴线对准。然后，壳体沿着相同的方向通过第二轧机机架在第二个插头上前进，同时从第一心轴剥离。通过使壳体能够通过第二塞子球磨机，而不需要从第一级心轴将壳体剥离的中间操作，实现了显着的时间经济。使用传统的塞子磨机设备和技术，塞子磨机代表无缝管生产中所涉及的操作顺序的瓶颈。相比之下，利用本发明的方法和装置，塞式磨机可以以比提供管状壳体的穿孔机更快的速度操作。这是通过对轧机设备投资的适度增加来实现的。
