DEVICE FOR MANUFACTURING FLEXIBLE TUBING, A FIXTURE AND A WELDING UNIT Russian patent published in 2007 - IPC F16L11/24 

FIELD: mechanical engineering, in particular, engineering of equipment for manufacturing flexible tubing used in systems for ventilation, air conditioning, transportation of substances, for protection of drive screws and guide rails from abrasive dust, etc.

SUBSTANCE: in the band-wrapping device for manufacturing flexible tubing the support is made with possible mounting of a fixture on it, assembled in advance for given standard size of tubing, and is additionally provided with a console for mounting a welding unit, the fixture and welding unit being made with possible removal. The fixture of band-wrapping device for making flexible tubing is made with possible mounting on support of device in form already assembled for given standard size of tubing and with possible removal from the support, where bases of the fixture are made with possible rotation relatively to each other and with possible fixation in a given position, which matches given standard size of tubing. Welding unit of band-wrapping device for making flexible tubing, comprising band feeding device, welding device and device for clamping overlapping of adjacent band coils, is made as a unit of aforementioned devices with possible mounting on the console of device for manufacturing flexible tubing and with possible removal from the console, where clamping device is additionally fitted with base, on which band feeding device and device for mounting the welding device are mounted, while the base itself is mounted with possible rotation relatively to horizontal axis of the device for manufacturing flexible tubing.

EFFECT: reduced time and labor costs of readjustment when changing to manufacturing of a tubing with different standard size.
