摘要： A rotating shear for cutting a rapidly moving wire has a pair of cutter heads rotatable about parallel axes and having respective blades. A drive synchronously counterrotates the heads about the respective axes with close juxtaposition of the blades on each revolution. Thus when the wire is between the heads level with the blades it is severed thereby. A guide tube surrounds the wire upstream of the heads and has a downstream end movable generally parallel to the axes and positioned adjacent and between the cutter heads. The wire exits from the guide tube in a direction generally perpendicular to the plane of the head axes. A guide head fixed to one of the cutter heads is formed with a generally helical guide groove centered on the respective axis. An axially and radially displaceable but angularly generally nondisplaceable follower can move between a position engaged in the groove and axially entrainable thereby and a position clear thereof. An actuator displaces the follower between the positions. A rigid link is connected between the follower and the guide tube so that when the follower is in the groove the tube can be pulled axially into and out of alignment with the blades for cropping of the wire and when out of the groove the tube can be moved independently of the head.

摘要： A wire shear has a pair of vertically superposed cutter drums defining a nip and having at least one cutter blade. These drums have parallel axes defining a vertical plane. A swingable elongated guide tube has a downstream end closely juxtaposed with and directed into the nip. This tube is mounted at its upstream end for swinging about vertical and horizontal axes at the upstream end. A wire is fed into the upstream end at high speed. A cooling sleeve surrounding the guide tube has lateral openings through which a coolant is introduced into the interior of the sleeve to cool the tube and the wire in it. An upstream guide is engageable upstream of the plane with the downstream end and with the wire issuing therefrom and extends into the drum nip substantially to the plane. A downstream guide downstream of the plane is aligned with the upstream guide and has a floor plate extending upstream substantially to the plane and a guide wall extending upstream past the plane and past the downstream end. The upstream guide can be raised to lift the downstream end of the guide tube and feed the wire issuing therefrom into the nip of the cutter drums.

摘要翻译： 电线剪切具有一对垂直叠置的切割滚筒，其限定了一个压区并且具有至少一个切割刀片。 这些鼓具有定义垂直平面的平行轴。 可摆动的细长引导管具有与下游端紧密并排并且指向夹持部的下游端。 该管安装在其上游端，用于在上游端围绕垂直和水平轴线摆动。 电线以高速送入上游端。 围绕引导管的冷却套筒具有侧向开口，冷却剂通过该开口被引入到套筒的内部以将管和其中的线冷却。 上游引导件可在平面的上游与下游端接合，并且导线从其上伸出并且基本上延伸到滚筒压区中。 平面下游的下游引导件与上游引导件对准，并且具有在基本上延伸到该平面的上游延伸的底板和在该平面上游延伸并经过该下游端的引导壁。 可以升起上游引导件以提升引导管的下游端并将从其引出的线材送入切割器滚筒的辊隙。
