Spiral welded pipe weld seam grinding and cleaning device

Abstract

The invention relates to a polishing and cleaning device for welded joints of helical welded pipes, and belongs to the technical field of polishing and cleaning for welded joints of helical welded pipes. The polishing and cleaning device for the welded joints of the helical welded pipes comprises a conveying device and a welded pipe fixing device. The feeding end of the welded pipe fixing device is connected with the conveying device, the discharging end of the welded pipe fixing device is provided with a rotating device, and a lifting device is arranged below the welded pipe fixing device. The rotating device is provided with an adjusting device, and the adjusting device is provided with a tool. The polishing and cleaning device for the welded joints of the helical welded pipes is simplein structure and easy to operate, and cleaning procedures are simplified. The helical welded pipes are conveyed through V-shaped conveying rollers and are clamped through clamping air cylinders, the position of the tool is adjusted through the adjusting device, welding slag of welded joints on the inner side and the outer side of the helical welded pipes can be rapidly and effectively cleaned away, the labor intensity of workers is relieved, the cleaning effect is ensured, and meanwhile, the production efficiency is improved.

Description

technical field [0001] The invention relates to a spiral welded pipe weld seam grinding and cleaning device, which belongs to the technical field of spiral welded pipe weld seam grinding and cleaning. Background technique [0002] After the weld seam of the existing spiral welded pipe is formed, the inner weld seam is ground by the inner weld seam grinder; the grinding wheel at the shaft end of the outer weld seam grinder is removed, and a wire brush is installed; the wire brush passes through the shaft It is fixedly connected with the rotating shaft of the external weld grinding machine, and can rotate with the rotating shaft of the external welding seam grinding machine; when the external welding seam grinding machine is started, the wire brush rotates under the drive of the rotating shaft, and the wire brush moves along the inner weld seam of the spiral welded pipe at the same time Removal of welding slag; manual disassembly, adjustment and replacement are required, the p...

Problems solved by technology

[0002] After the weld seam of the existing spiral welded pipe is formed, the inner weld seam is ground by the inner weld seam grinder; the grinding wheel at the shaft end of the outer weld seam grinder is removed, and a wire brush is installed; the wire brush passes through the shaft It is fixedly connected with the rotating shaft of the external weld grinding machine, and can rotate with the rotating shaft of the external welding seam grinding machine; when the external welding seam grinding machine is started, the wire brush rotates under the drive of the rotating shaft, and the wire brush moves along the inner weld seam of the spiral welded pipe at the same time Removal of welding slag; manual disassembly, adjustment and replacement are required, the process is more complicated, and the cleaning effect is not good, so it is very important to develop a spiral welded pipe weld grinding and cleaning device
