Necking station transfer device of oil casing thread machining production line

Abstract

The utility model relates to the technical field of oil casing machining, in particular to a necking station transfer device of an oil casing thread machining production line. The device comprises a position covering mechanism and a pipe blocking mechanism, the position covering mechanism comprises a position covering guide rail section and a fishplate, the position covering guide rail section can be installed at a fracture of a production line guide rail body so that a continuous and complete guide rail can be formed on the production line guide rail body, and the pipe blocking mechanism can be arranged on the portion, on one side of a pipe coming from the fracture, of the production line guide rail body. The pipe blocking mechanism comprises a pipe blocking block arranged on the production line guide rail body. When the oil casing does not need to be subjected to pipe end necking processing, the oil casing can directly roll to pass through a guide rail at a casing necking process, staying is not needed, a lifting mechanism of casing necking processing equipment is not needed, the oil casing is lifted to pass through a pipe stopper and a fracture, invalid operation of the equipment is avoided, energy consumption is reduced, operation is convenient and flexible, and production efficiency is improved. And the sleeve machining efficiency is improved.
