Vertical circular seam welding machine

Abstract

Belonging to the field of welding equipment, the invention relates to a vertical circular seam welding machine applied to thin-wall stainless steel tee bellmouth non-oxidation welding. The welding machine comprises an operating platform, a driving device, a welding gun and a slewing mechanism for causing the product to be processed to rotate with the slewing mechanism in a matched manner; the slewing mechanism comprises a principal axis and the driving device; a principal axis mounting hole is arranged on the operating platform, and the principal axis is matched with the principal axis mounting hole; and the lower end of the principal axis is connected with the driving device, the upper end thereof is provided with a stationary axis for fixing the product to be processed, a through hole for conveying shielding gas is arranged in the principal axis, air holes are arranged on the stationary axis, the air holes are communicated with the through hole in the principal axis, and the welding gun is fixed on the operating platform by a welding gun seat. With the welding machine of the invention, the product clamping process can be simplified, and the welding efficiency and welding quality can be improved, as a result, the purpose that pipe fittings are oxidized neither internally nor externally after being welded is achieved; and meanwhile, the labor intensity is greatly reduced and the welding time is shortened.

Description

technical field [0001] The invention belongs to the field of welding equipment, and relates to a welding machine, in particular to a vertical girth welding machine for oxidation-free welding of thin-walled stainless steel tee sockets. Background technique [0002] As we all know, limited by the poor ductility of stainless steel materials, the production of thin-walled stainless steel tees for fluids cannot be directly stretched and formed with thin-walled welded pipes. Only the middle head can be stretched for a short period, and then welded straight after the cut To ensure the length of the socket, there are two main production processes currently used for welding stainless steel tee fittings. One is manual argon arc welding, which is characterized by low efficiency, uneven welding, and low pass rate. It is usually used for sample production Or small batch production of new products; Another method is to use horizontal girth welding machine welding, which has the advantages...
