摘要： A chain tube cutter has two plier-like levers with hand grips on one side of a pivot pin which projects from one lever through a slot in the other and chain-engaging arms on the other side of the pivot pin. A link cutting chain is secured to one arm. The other arm has notches for engaging a selected link of the chain after it is wrapped around the tube to be cut. Squeezing the hand grips together generally keeps the chain adjusted about the tube as it is cut by rotating the cutter relative to the tube, but to provide greater initial and operational adjustment, the pivot pin is variably positionable in the slot.

摘要： A necking-out tool for forming projecting cylindrical nipples or necks on the circumferential wall of a pipe container or the like. The tool has a screw plug having a hook-shaped forming head and a thrust sleeve provided with a coaxial downholder flange for cooperation with the forming head and the screw plug. The thrust sleeve also has a hollow cylindrical interior corresponding to the contour of the forming head for the reception of the formed nipple or neck. A non-rotatable, telescopic guide means is associated with the thrust sleeve for mounting a torque converter on the screw plug.

摘要： A tool for enlarging pipe ends includes a toolholder body containing an axially movable mandrel having a tapering end and capable of being displaced by an externally applied force. A toolhead is exchangeably attached to the toolholder body coaxially with the mandrel and contains a plurality of expanding members in the form of cylindrical segments radially displaceable by the axial displacement of the mandrel and mounted so that they project axially from the toolhead. The edges of the segments facing the mandrel form a recess corresponding to the mandrel taper. An adapter is interposed between the toolholder body and the toolhead and has a body containing an axially displaceable supplementary mandrel having an elongated tapering end for cooperating with the exchangeable toolhead. The other end of the supplementary mandrel contains a recess shaped to receive the tapering end of the mandrel mounted in the toolholder body.

摘要： A bending device for metal pipe with and without plastic jacketing has a short cylindrical segment including a circumferential groove which determines the bending radius of the pipe to be bent and a support for holding the pipe to be bent tangentially with respect to the groove. A lever is mounted for concentric pivotable movement about the segment and a pressing block is mounted on the lever for pivotal movement about an axis parallel to the segment axis. The pressing block has a working surface which has an approximately semicircular, concave cross section in a plane disposed parallel to the pivot axis of the pressing block and the segment axis and a concave cross section in a plane disposed perpendicular to those axes.

摘要： An expanding head for pipe end enlarging tools which have a tool body including a cylindrical end portion and a removable mandrel having a tapered end extending through the cylindrical end portion of the body and axially movable therein. The expanding head comprises a plurality of exchangeable segmental expanding elements each having a flange segment which together form a radially outwardly extending annular flange. The segments are connected together to unite them as a self-contained set and for radial movement in response to axial movement of the mandrel when in use. The segments are connected by a spring element which surrounds the segments at the annular flange and clamps them against each other and against the mandrel. The segments are removably connected to the cylndrical portion of the tool body without detachment of the spring element to maintain the segments in the self-contained set. This removable connection is carried out by a sleeve connectable to the cylindrical portion of the tool body coaxially with the mandrel and having an inwardly extending annular flange positionable behind the annular flange of the segments to coact therewith to mount the segments in position around the mandrel.

摘要翻译： 一种用于管端扩大工具的膨胀头，其具有包括圆柱形端部的工具主体和具有延伸穿过主体的圆柱形端部的锥形端的可移除的心轴，并可轴向移动。 膨胀头包括多个可更换的节段膨胀元件，每个元件具有一起形成径向向外延伸的环形凸缘的凸缘段。 这些段连接在一起以将它们作为独立的组合组合，并且在使用时响应于心轴的轴向运动而进行径向运动。 这些节段通过弹簧元件连接，该弹簧元件围绕环形凸缘处的节段并且将它们彼此夹紧并抵靠心轴。 这些段可拆卸地连接到工具主体的圆柱形部分，而不会弹簧元件的分离，以将段保持在独立的组中。 该可移除连接由可连接到工具主体的圆柱形部分的套筒执行，该套筒与心轴同轴并且具有向内延伸的环形凸缘，该环形凸缘定位在段的环形凸缘的后面，以与其相配合，以将段安装在围绕心轴的位置。
