摘要： A tool for cutting a hollow profile is designed both for cutting a flange on the hollow profile and for forming the hollow profile using an internal high pressure forming process. The tool has at least one cutting device which extends parallel to the longitudinal extent of the hollow profile, has a cutting edge and is displaceable transversely to the hollow profile. A side of the cutting device that faces the hollow profile is designed as a shaping die wall, against which the hollow profile bears at least during the internal high pressure forming. In addition, the tool my have an integrated embossing punch and also a perorating punch formed coaxially thereto, thereby also enabling optional embossing and/or perforating of the hollow profile in addition to the cutting and the internal high pressure forming.

摘要： A tool (1) for the internal high pressure forming of a hollow section (2). The tool (1) is designed both for forming the hollow section (2) and for making an embossment on the outside of the hollow section (2) and for making a hole in the hollow section (2). For this purpose, the tool (1) has an embossing punch (11) displaceable transversely to the longitudinal extent of the hollow section (2) and also a perforating punch (13) arranged coaxially in the embossing punch (11).
摘要翻译：一种用于中空部分（2）的内部高压成形的工具（1）。工具（1）被设计成用于形成中空部分（2）并且在中空部分（2）的外侧上形成压花并且在中空部分（2）中形成孔。为此，工具（1）具有横向于中空部分（2）的纵向延伸的位移的压花冲头（11），以及同轴地布置在压花冲头（11）中的穿孔冲头（13）。

摘要： The invention relates to a process and apparatus for manufacturing hollow sections with cross-sectional expansions in end portions thereof. A hollow blank is widened and calibrated by internal high pressure forming by means of a forming tool receiving it, and, after the calibration, is separated in the area of the widening while forming two hollow sections with cross-sectionally widened ends facing one another in the separated position. In order manufacture from a hollow blank hollow sections with the lowest possible reject rate and therefore in a reliable process, which are cross-sectionally widened on the end side by means of high degree for forming, the blank is widened while the forming tool is open and is simultaneously upset to form a rotationally symmetrical bulging hollow section by means of a pressure force which is axially directed from the outside to at least one of the two blank ends.
摘要翻译：本发明涉及一种用于制造在其端部具有横截面扩展的中空部分的方法和装置。通过内部高压成型加工空心坯料并通过接收它的成形工具进行校准，并且在校准之后，在加宽区域中分离，同时形成两个具有横截面加宽的端部朝向彼此的中空部分分离位置。为了从具有最低可能废品率的中空坯料中空部分制造，因此在可靠的工艺中，通过高度成形在端侧横截面加宽，坯料在成形工具打开时变宽同时由于从外部轴向地指向两个空白端中的至少一个的压力而同时产生旋转对称的膨胀中空部分。
