Abstract
A device for removing external circular fins from pipe joints comprising a base, a hollow rotor with a faceplate mounted in the base, carriages located on the rotor faceplate, a mechanism for radial traverse of the carriages, having a holder rotatably fitted on the rotor, and a drive for the rotor and the mechanism for traversing the carriages. Each of the carriages is provided with a roller adapted to trace over the surface of the pipes being treated, while the mechanism for radial traverse of the carriages is composed of links with one of their ends articulated to the holder and with the other end to slide blocks, each of which is housed in a bore in the respective carriage with the possibility of radial movement therein and is connected to a spring gauged for the cutting force, the other end of which spring thrusts against the bottom of the carriage bore. The drive of the rotor and of the carriage traversing mechanism has two output shafts, of which one is kinematically associated with the rotor, while the other shaft is kinematically associated with the holder, which drive is provided with a mechanism for program control of the difference between the rotational speeds of the shafts.
