    • This flaw-removal device prevents overlooking of flaws in the automatic flaw-cutting process by rectifying the twist of a wire-shaped metal drawn from a cannon-shaped wire supply stand, further promoting efficiency in removing remaining flaws by applying the automatic flaw-cutting process and removing the uncut flaws by hand. In this invention, a twist-rectifying drum 3 is installed in front of a flaw-detecting device 4. It then becomes possible to rectify the twisting of the wire-shaped metal by winding the wire-shaped metal installed on a cannon-shaped wire supply stand around the twist-rectifying drum in a length longer than one turn of the coiled wire-shaped metal so that the wire-shaped metal is freely mounted on the drum. It also becomes possible to remove an uncut flaw by hand by installing a flaw-check and removal site 10 having a specified span between drawing dies 8 and a wire-drawing drum 9, and by stopping the portion of the wire-shaped metal having uncut flaws at the site 10.
    • 该除锈装置通过整流从炮形供电台拉出的线状金属的扭曲来防止自动瑕疵切割过程中的缺陷,从而通过应用自动瑕疵切割来进一步提高除去剩余缺陷的效率 手工处理和清除未切割的缺陷。 在本发明中,将扭转矫正滚筒3安装在探伤装置4的前面。然后,可以通过卷绕安装在炮制线上的线状金属来矫正线状金属的扭曲 供应站在扭转矫正滚筒周围长于螺旋线形金属的一圈的长度,使得线状金属自由地安装在滚筒上。 通过在拉丝模具8和拉丝滚筒9之间安装具有规定跨度的缺陷检查和移除部位10,并且通过停止具有未切割的线状金属的部分,也可以用手去除未切割的缺陷 现场缺陷10。

    • Apparatus for externally and internally peeling pipes includes a drill head secured to one end of an elongated drill rod and an external cutter head longitudinally-spaced from the drill head in the direction of movement of a pipe through the apparatus. A feed mechanism is positioned adjacent the drill head for feeding a pipe completely past the drill head and at least partially through the external cutter head. An extraction feed mechanism is positioned on the opposite side of the external cutter head from the drill head for pulling pipes completely past the external cutter head. The feed mechanism adjacent the drill head includes opposed pairs of rollers, one pair of which is radially aligned with the cutters on the drill head.
    • 用于外部和内部剥离管道的装置包括固定到细长钻杆杆的一端的钻头和沿着管道穿过该装置的运动方向与钻头纵向间隔开的外部刀头。 馈送机构位于钻头附近,用于将管完全穿过钻头并且至少部分地穿过外部刀头。 提取进给机构位于外刀头的与钻头相反的一侧,用于将管完全拉过外刀头。 与钻头相邻的进给机构包括相对的一对辊,其一对与钻头上的切割器径向对准。
