图1为精确切削管端工具横向简图,图2为纵向简图,图3示刀具的布置。从图1和图2,11为待加工的,直径从760到1220毫米或更大的钢管。13为夹紧瓦。当夹紧瓦径向外移时,它能将紧贴着管子内壁。夹紧瓦13用幅向布置的杆15支撑,后者由一只或数只圆形导环17导引。杆15可用凸轮或肘节推出(夹紧位置)和拉进(放松位置)。图2所示的肘节包括:可纵向移动的中心轴21,肘节杆23以及与中心轴21相接连的中心毂25。每一只
Figure 1 is a schematic lateral cross-sectional view of the tool for precise cutting, Figure 2 is a schematic longitudinal view, Figure 3 shows the cutter arrangement. From Figure 1 and Figure 2,11 is to be processed from the diameter of 760 to 1220 mm or more steel. 13 for clamping the tile. When the clamping shoe moves radially outwards, it can abut against the inner wall of the pipe. The clamping shoes 13 are supported by means of a bar 15 arranged in a widthwise direction which is guided by one or more circular guide rings 17. The rod 15 can be pushed out (clamping position) and pulled (released position) with a cam or a toggle. The toggle shown in FIG. 2 includes a longitudinally movable central shaft 21, a toggle lever 23, and a central hub 25 connected to the central shaft 21. Each one
