摘要： A system for notching tubes to facilitate their joinder to other tubes or rods, in which a first portion of the notch is formed by a rotary cutting action extending progressively inwardly into the tube side wall and then outwardly in an arcuate path, and the second portion of the notch is formed by a plunging, shearing action which simultaneously punches the entire second portion of the notch out of the wall of the tube. The apparatus for forming each of the notches preferably includes a pair of die halves which together define a tube receiving passage intersected by a tool receiving passage, and a cutting tool positioned in the tool receiving passage. The tool is provided with a substantially axially extending rotary cutting edge for forming the first portion of the notch and a shearing edge for punching out the second portion of the notch when the tool is plunged through the wall of a tube positioned in the intersection of the tube and tool receiving passages. In one form of the invention, two sets of tools and dies may be provided for simultaneously shaping both ends of a tube and a conveyor may be provided for carrying the tubes into and removing them from the tool and die sets.

摘要翻译： 一种用于切割管以便于与其他管或杆接合的系统，其中通过逐渐向内延伸到管侧壁然后向外延伸的弓形路径的旋转切割动作形成凹口的第一部分，并且第二部分 该切口通过一个插入的剪切动作形成，该动作同时将整个槽口的第二部分冲出管的壁。 用于形成每个凹口的装置优选地包括一对半模，其一起限定与工具接收通道相交的管接收通道，以及定位在工具接收通道中的切割工具。 该工具设置有基本上轴向延伸的旋转切割刃，用于形成切口的第一部分，以及剪切边缘，用于当刀具穿过定位在该切口的相交处的管的壁上时，冲切掉切口的第二部分 管和工具接收通道。 在本发明的一种形式中，可以提供两组工具和模具，用于同时成形管的两端，并且可以设置输送器用于将管子运送到工具和模具组中并将其从工具和模具组件中移出。
