ASSEMBLY COMPLEX FOR MANUFACTURING OF TWISTED HEAT EXCHANGERS Russian patent published in 2020 - IPC F28D7/02 B21D11/06 

FIELD: machine building; power engineering.

SUBSTANCE: invention relates to power engineering and can be used in production of heat exchangers. Assembly complex for manufacture of twisted heat exchangers includes a slipway with front and rear headstock installed on it for rotation along horizontal axis of mandrel with heat exchanger, spindle with clamp for heat exchanger mandrel, moving in horizontal direction support with installed on it central control panel and cabinet, as well as with pipe winding device fixed on pedestal, spindle drive with electronic adjustment of rotation speed is located in front head, front and rear headstocks are raised vertically from horizontal axis of rotation by means of front and rear transition supports to height of 0.7–1.0 m from axis of spindle, at that rotation of heat exchanger mandrel is transmitted from spindle through two gears installed in front transition support.

EFFECT: pedestal can smoothly move in vertical plane, and tail stock, except for movement along axis of rotation, can move across axis of mandrel rotation along guides with possibility of disconnection from mandrel of heat exchanger.
