    摘要： A method of lining a main fluid conduit 1 having a branch conduit 2 and apparatus for use in the main conduit includes a carrier 7 which is longitudinally displacable in the conduit 1. A portion 9 of the carrier is rotatable above a longitudinal axis and carries a scissors-type extendible linkage 10 having a platform 11. By rotation of the portion 9, displacement of the carrier 7, and extension of the linkage 10, service structure on the platform 11 can be maneuvered to be located in the branch conduit 2. The service structur=e may be a water jet cutter or a locating member 15 having a chamber which is expandible by fluid pressure to engage the sides of the conduit 2 and be retained therein. The locating member 15 includes a metallic part which a metal detector can detect through a lining which is fitted in the main conduit 1 to determine the position at which a port has to be cut in the lining to coincide with the branch conduit 2. Preferrably the chamber of the of the locating member 15 is expanded by fluid pressure through a hose 20 and non-return valve so that the hose 20 disengages automatically at a predetermine pressure to isolate the locating member in the conduit 2 when the platform 11 is withdrawn.

    摘要： The subject piercing die is particularly adapted for piercing a hole in a blank having an open interior and an outer wall defining a closed figure. The piercing is done from the interior of the blank through the wall to the outside of the blank. The piercing die includes a base with a slide movably mounted on the base. A guide is movably connected to the slide to control movement of the slide to a straight line movement. A female die having a blank receptacle for holding the blank is mounted on the base. The female die has a cutting aperture extending through a portion of the female die and intersecting the blank receptacle. A male die is mounted on the slide and is positioned within the blank receptacle for mating with the cutting aperture to cut a hole in a blank positioned in the receptacle. The male die cuts a hole in the blank from the interior of the blank through the outer wall to the outside of the blank. A cam is connectable to the slide for moving the male die toward the female die to engage the blank and to cut the hole in the blank.

    摘要翻译： 主题穿孔模具特别适用于刺穿具有限定封闭图形的敞开内部和外壁的坯料中的孔。 穿孔是从空白的内部通过墙壁到空白的外部完成的。 穿孔模具包括具有可移动地安装在基座上的滑块的底座。 引导件可移动地连接到滑块以控制滑块的运动到直线运动。 具有用于保持坯料的空白容器的阴模安装在基座上。 阴模具有延伸穿过阴模的一部分并且与坯料容器相交的切割孔。 阳模安装在滑动件上并且位于坯料容器内以与切割孔配合以在位于容器中的坯料中切割孔。 阳模从坯料的内部通过外壁到空白的外侧切割坯料中的孔。 凸轮可连接到滑动件，用于将阳模移动到阴模以与坯件接合并切割坯料中的孔。

    摘要： This invention provides a method of and apparatus for punching apertures in the walls of square sectioned steel tube. An elongated square sectioned mandrel is supported horizontally by and is connected at a rear end to roller decking so that a square tube can be fed onto the mandrel and can be used to feed the tube off the mandrel step by step, while between steps the tube is punched at the front end of the mandrel by a punch die on a punch head which moves laterally of the mandrel and into a punch recess in the mandrel. The punch head also has a guide pin which engages a guide recess in the mandrel before the punch die engages the punch recess to ensure that the punch die and punch recess are accurately aligned and that the apertures will be evenly spaced along the length of the tube.
