Abstract

The invention discloses an aluminum and aluminum alloy spiral tube molding welding device. The aluminum and aluminum alloy spiral tube molding welding device is characterized by mainly comprising a spiral tube molding device fixedly installed at one end of a machine frame and a stirring friction welding device fixedly installed at the other end of the machine frame. The stirring friction welding device mainly comprises a high-speed motor, a stirring head connected to an output shaft of the high-speed motor and comprising a stirring needle and two shaft shoulders and at least two sets of rotary rollers arranged on the stirring friction welding device in a rotary mode. The aluminum and aluminum alloy spiral tube molding welding device is wide in adaptation, high in efficiency and capable of satisfying welding production of aluminum and aluminum alloy spiral welding tubes of various types.

Description

technical field [0001] The invention relates to the field of aluminum and aluminum alloy welding, in particular to an aluminum and aluminum alloy spiral tube forming welding equipment. Background technique [0002] Aluminum and aluminum alloy spiral tubes are made by rolling aluminum and aluminum alloy coils into tube blanks at a certain helical angle, and then welding the tube seams. Pipes with different diameters can be produced by continuous crimping and welding of coils of the same width, which are widely used in electrical, petrochemical and low-temperature storage tanks and other fields. [0003] Different grades of aluminum alloys have different welding characteristics. In the spiral welded pipe production line, any traditional welding method such as fusion welding, resistance welding, gas welding, plasma arc welding, electron beam welding, vacuum diffusion welding, etc. cannot meet the needs of welding different grades of aluminum alloys. Therefore, there is an urg...
