Steel tube stitching machine

Abstract

The invention relates to a steel tube stitching machine comprising a main machine, electric material support rollers, electric material turning rollers, electric trolleys, material solidifying devices and a rail, wherein the main machine is fixedly installed on a foundation, an electric material support roller and an electric material turning roller are installed on the feed side, an electric material turning roller and a material solidifying device are installed on an electric trolley on the feed side, an electric material support roller is also installed on the discharge side, and a material solidifying device is also installed on an electric trolley on the discharge side. The main machine of the steel tube stitching machine provided by the invention has a reasonable body structure, thus saving materials; the steel tube stitching machine can be used for performing stitch welding on cylindrical steel tubes and conical steel tubes and performing electric feeding and electric rotation on steel tubes, thus lightening the labor intensity; and the workbench of the steel tube stitching machine can be adjusted up and down, thus prolonging the service life of the support rollers.

Description

technical field [0001] The invention relates to a steel pipe processing machine, in particular to a steel pipe seaming machine. Background technique [0002] At present, the steel pipe seaming machine used for straight seam steel pipe welding on the steel pipe tower consists of a main machine and idlers on the inlet and outlet channels. Due to the long processing of steel pipes, multiple sets of rollers are installed on the feed and discharge channels, and some also lay tracks on the feed and discharge channels, and mobile support rollers are placed on the tracks. The length of the steel pipe is used to adjust the position of the movable idler. The movable idler does not move during work, and the transportation of the steel pipe is still achieved by the rotation of the idler. Therefore, multiple sets of idlers are still required, which increases the cost; There is a certain gap between the fixed workbench and the steel pipe. When the seam is closed, the supporting roller is...

Problems solved by technology

Due to the long processing of steel pipes, multiple sets of rollers are installed on the feed and discharge channels, and some also lay tracks on the feed and discharge channels, and mobile support rollers are placed on the tracks. The length of the steel pipe is used to adjust the position of the movable idler. The movable idler does not move during work, and the transportation of the steel pipe is still achieved by the rotation of the idler. Therefore, multiple sets of idlers are still required, which increases the cost; There is a certain gap between the fixed workbench and the steel pipe. When the seam is closed, the supporting roller is compressed and deformed, which reduces the service life of the supporting roller; different pressure heads need to be replaced when processing straight or tapered pipes; manually turning the steel pipe is low in efficiency and labor-intensive. strong
