For automatic linear advance, Petig uses a robust and precise toothed belt system with a repeatability of ±0.15mm. With this system, tubes and sections up to a length of 7,000mm can be machined without rechecking. Once the sections have been stamped, the feed measuring carriage (VMW) travels back to its starting position. The sections remaining in the stamping tool are transported away linearly with pneumatic grippers. The column-guided hole-stamping tools are made of hardened and ground high-performance tool steel.

For stamping purposes, the two sections to be processed on a machine are manually placed on the roller feed table and then pushed into the collet chuck on the feed measuring carriage (VMW). The collet chucks close automatically when the sensor is reached. During stamping the sections are cycled by the machine, whereby groups of 8 holes are always stamped (square, slotted and round holes). It is also possible to carry out other operations simultaneously, such as lowering and beading.

Friedrich Petig GmbH’s range of section and tube stamping machines includes Cleff, DaimlerChrysIer, Heras, Hansa Merten, Rautakari and Syspal. The machines feature particularly robust and user-specific manufacturing. In the manufacturing of shelf, shop building and fencing systems, a key condition is the use of deformation-free tubes, which cannot always be guaranteed. Since the introduction of the mandrel expansion die, hollow sections and tubes have been stamped without this otherwise inevitable deformation. Petig will present their combined section and tube stamping machine for open C- sections and a multitude of different tube sections. The maximum section lengths that can be stamped are 6,000mm. The press design is a double C-frame (portal construction) with a stamping force of 2 x 800kN. fi Petig’s combined section and tube stamping machine for open C-sections
