Process for the partial renewal of flights of chain belts in trough conveyors

摘要

A process for the partial renewal of flights of chain belts in trough conveyors, especially those in underground operations, in which abraded partial areas of the flight are brought to specified size, includes operating a tool 34 with rectilinear motion to press into at least one of the two surfaces or into a longitudinal surface of the part to be repaired that is perpendicular to said surface and local pressure is applied and the area of the part to be renewed is compressed with the material displaced into a cavity 37 of a drop-forge die 30 that has the specified dimensions of the flight.
