Abstract
1. Способ изготовления гофрированных труб из термопластов экструзией путем выдавливания из головки с кольцевой щелью трубообразной заготовки с последующим формованием ее в гофрированную трубу во вращающемся охлаждаемом резьбовом калибре за счет разности давления воздуха снаружи и внутри заготовки, отличающийся тем, что наружную поверхность заготовки перед формованием смазывают водой и формуют ее сжатым воздухом, подаваемым в полость заготовки. ! 2. Устройство для осуществления способа по п.1, содержащее экструдер, головку с дорном и мундштуком и вращающийся охлаждаемый резьбовой калибр с радиальными отверстиями по вершинам формующей резьбы, отличающееся тем, что радиальные отверстия выполнены только на участке, соответствующем концу мундштука, введенного внутрь калибра, а на конце мундштука установлена втулка с уплотнительными кольцами по диаметру мундштука, жестко соединенная с калибром.1. A method of manufacturing corrugated pipes from thermoplastics by extrusion by extruding a tube-shaped workpiece from a head with an annular slot with its subsequent molding into a corrugated pipe in a rotating cooled threaded gauge due to the difference in air pressure outside and inside the workpiece, characterized in that the outer surface of the workpiece is lubricated before molding water and mold it with compressed air supplied to the cavity of the workpiece. ! 2. The device for implementing the method according to claim 1, containing an extruder, a head with a mandrel and a mouthpiece and a rotating cooled threaded gauge with radial holes along the tops of the forming thread, characterized in that the radial holes are made only in the area corresponding to the end of the mouthpiece inserted inside the gauge and at the end of the mouthpiece there is a sleeve with o-rings along the diameter of the mouthpiece, rigidly connected to the caliber.
