New punch marking system for large tube and pipe

marking position and are used to calculate the diameter of the pipe. Once the ‘marking start’ signal is received by the marking system the robot searches for the pipe end position by means of a mechanical detection unit that is mounted next to the stamping head on axis 6 of the robot. Once the pipe position and diameter have been established, the marking image is stamped in a curved manner around the machined bevelled surface. It is possible to undertake front side and bevel marking, with flexible character size. If marking is required on the other end of the pipe then it is repositioned and the marking sequence is repeated on the other end. The marking data, pipe wall thickness, diameter and angle are automatically fed into the marking machine control unit by the host computer or via the operator panel. Other product data – for example character size, and shape of bevel – are manually input via the operator panel.

Numtec-Interstahl GmbH, Austria, has introduced a fully automated marking machine based on a standard industrial robot. The machine’s marking head is based on single stamping needle technology and is installed on axis number 6. The machine is designed to apply an identity onto the machined ends of a

pipe. Varying bevelled angles can be accommodated. The machine undertakes permanent ID-marking and no consumables are used (like ink or paint). The pipe is positioned on a conveyor with the machine surface facing toward to the stamping machine. Two stationery laser detectors are mounted adjacent to the
