DEVICE FOR MANUFACTURING PIPES FROM COMPOSITE FIBER MATERIALS Russian patent published in 2008 - IPC B29D23/00 B29C53/56 

FIELD: mechanical engineering.

SUBSTANCE: device comprises mandrel, member for filling the mandrel with a filler, polymerizing furnaces, and support that are mounted on the base. The support is made of a pillar secured to the base, race, and ring mounted inside the race. The race and ring are mounted for permitting rotation with respect to the vertical axis of the device. The race is provided with supporting rollers that are in a contact with the outer side of the ring and face rollers that are in a contact with the ring surfaces. The bearing roller underlies the ring and has a drive for forced rotation with a controlled speed of rotation. The axis of rotation of the face rollers are arranged tangentially to the ring. The supporting outer roller may be arranged from the side or from the top of the ring. The drive for forced rotation is connected with the bearing roller through the clutch with the variable torque. The race receives the pickups of longitudinal movement of the pipe. The signals from the pickups are transmitted to the controlled drive and clutch through the control system for measuring velocity and torque. The face rollers may be connected to the flexible plates and the plates may be provided with pickups of direction and value of the axial loading acting on the ring from the side of the mandrel with pipe. The device may be provided with the drive for forced rotation of the race with the ring with respect to the vertical axis of the device . The signal from pickups of axial loading is transmitted to the drive of the forces rotation of the race with ring through the control system.

EFFECT: enhanced efficiency.
