DEVICE TO PRODUCE TUBE WITH SCREW CRIMPS Russian patent published in 2010 - IPC B21D15/04 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming and can be sued in production of tubes with screw crimps. Forming rolls and tube transfer mechanism are arranged on the device foundation. Rolls are mounted around the device axis and at an angle to it to revolve on their axles. Tube transfer mechanism comprises housing with the drive to move the mechanism along its axis and radially-driven clamping elements arranged inside aforesaid housing. Besides tube transfer mechanism incorporates extra sets of radially-driven clamping elements that revolve about the device axis and translate along it. Said extra clamping elements are designed to clamp the tube in turns nearby forming rolls and release it on reaching preset distance from forming rolls in tube work stroke.
