Abstract

The invention relates to the technical field of steel pipe welding clamping, and discloses a seamless steel pipe clamping mechanism. The seamless steel pipe clamping mechanism comprises a base; the base is a hollow mechanism; two clamping devices are symmetrically arranged above the base; and a moving mechanism for butt joint with the two clamping devices is arranged in the base. The seamless steel pipe clamping mechanism can improve the seamless steel pipe clamping effect, and meanwhile, can improve the seamless steel pipe butt welding stability.

Description

technical field [0001] The invention relates to the technical field of welding and clamping of steel pipes, in particular to a clamping mechanism for seamless steel pipes. Background technique [0002] Seamless steel pipes are steel pipes made of a single piece of metal with no seams on the surface, called seamless steel pipes. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, and jacking pipes. According to the cross-sectional shape, seamless steel tubes are divided into two types: round and special-shaped, and special-shaped tubes have various complex shapes such as square, oval, triangular, hexagonal, melon-shaped, star-shaped, and finned tubes. The maximum diameter is 650mm, and the minimum diameter is 0.3mm. Depending on the application, there are thick-walled tubes and thin-walled tubes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes ...
