The development of the tube bender have been resolved within the Corporate Research and Development Program IMPULS which was realized under financial support from the Czech household budget through the Czech Ministry of Industry and Trade.
This product links to the successful types of the XOTR, XOTM a XOTL series. The machine is primarily designed for professional industrial manufacture, for spatial cold tube bends, although its concept makes is also suited for the needs of piece- and small series manufacture.
It is designed for bending thin-walled and thick-walled steel tubes up to Ø 80 mm.
The tube bender allows the clamping of tubes measuring between the start of first bend to the end of tube up to 3600 mm. For still longer tubes special equipment must be ordered.
The movement of all mechanisms is maintained by the hydraulic equipment of the tube bender through the hydraulic unit with the respective compressed-oil distributors. A tube bend is performed by hydraulic cylinder, which is connected to three-row roller chain guided over two chain wheels. A chain wheel drives the bending arm, which carries the hydraulic cylinder for clamping the tube to the segment. When performing a bend, the bending segment is driven along with the bending arm. The return of the segment is ensured by slow-running hydraulic motor.
The lengthwise tube feed between individual bends is carried out using the slide equipped with collet chuck, the slide being driven by slow-running hydraulic motor over pinion and toothed rack. The turning the tube around its longitudinal axis allows the execution of individual bends in various planes in space. The rotation is ensured by slow-running hydraulic motor over worm and worm gear.
The tube bending machine is controlled by the Siemens S7-CPU 314 control system. The operation is via the TP177B touch panel located on portable support stand. The control system allows tube bending in both manual and automatic mode. The control panel communicates with the operator through pre-selected screens, so called frames. The operation via the frames is transparent and rather intuitive.
