Workpieces with a special end form geometry require exact parameters for an efficient implementation. Satisfying this requirement is the objective of a new axial tube forming machine with automatic tool detection for tube forming.

REB 645 from transfluidThe starting point for the REB 645 from transfluid is a barcode scanning system, which enables the operation data of a tube with individual barcode to be easily read. For this purpose, all the tools of the machine, which is equipped with six forming stations, have radio frequency (RFID) sensors. This is intended to ensure that the right program and the appropriate tools are made available consistently and reliably.

If the automatic inspection unit detects a wrong tool, the operating panel with data memory displays this information immediately as well as the identity of the correct tool for the change. A system with fork for fixing and locking bolt for securing the mount then allows the machine operator to change the tool as indicated and then to proceed to the tube end forming. According to the company, this system means that the machine operator can change the tools in a time-efficient manner so there is minimal downtime.

The REB 645 allows the axial forming of tubes with diameters from 6-45 mm, which is accomplished by means of a servomotor. Options exist for electric or hydraulic numeric drives. In addition, rolling stations for specific forming processes can be integrated. In case of extremely short cycle times, these forming procedures can also be carried out gradually in transfer systems.
