Pipe fitting pipe orifice shaping machine used for pipeline welding

Abstract

The invention discloses a pipe fitting pipe orifice shaping machine used for pipeline welding in the technical field of pipe orifice shaping machines. The pipe fitting pipe orifice shaping machine comprises a base, a gear is mounted at the power ends on the left sides of motors through a speed reducer, and the top of the gear is engaged with the bottom of a transmission gear. A pipe orifice shaping assembly is mounted at the top of a threaded adjusting rod through a bearing, limiting rods are arranged on the left side and the right side of the joint of the outer wall of the bottom of the pipeorifice shaping assembly and the threaded adjusting rod, and the bottoms of the limiting rods extend to the outer wall of the bottom of the base. After a pipe fitting is fixed, the threaded adjustingrod is rotated so that the pipe orifice shaping assembly can ascend, at this moment, a lower press roller and the outer wall of the bottom of the pipe fitting are located on the same horizontal line,then a lead screw is rotated so that a U-shaped moving seat can move towards the left side, at this moment, the outer wall of the bottom of the pipe fitting is located between an upper press roller and the lower press roller, a threaded rod is rotated again so that a moving plate can descend, at this moment the upper press roller abuts against the inner wall of the pipe fitting downwards, the motors drive the pipe fitting to rotate, and a pipe orifice can be shaped.

Description

technical field [0001] The invention relates to the technical field of nozzle shaping machines, in particular to a pipe fitting nozzle shaping machine used for pipeline welding. Background technique [0002] The common connection methods of metal pipes are flange and welding. When welding pipes, the roundness consistency of the weld joints is relatively strict. If the roundness consistency accuracy at the pipe mouth is not enough, the weld seam will increase. , will cause welding defects such as burn-through, missing welding, and incomplete penetration. At present, the commonly used shaping method is to weld the aligned part at the entire welding joint first, and then use heating and hammering methods to force the heated part to deform, but this The shaping effect of this method is poor, and it is difficult to maintain the accuracy by manual operation. Therefore, we propose a pipe fitting nozzle shaping machine for pipe welding. Contents of the invention [0003] The obje...
