The invention discloses an anti-deformation welding machine special for a thin-wall cylinder, belongs to the technical field of mechanical welding, and aims to solve the problems that welds are difficult to form during butt welding of two thin-wall round pipes, cracks, included slag and pores are easily generated, and the thin-wall round pipes have a large deformation amount after being welded. A rear flange is fixedly connected with a front flange through internal hexagonal bolts A; an adjustment sleeve is fitted to the rear flange and the front flange respectively and fixed through the internal hexagonal bolts A; a moving handle is connected with the adjustment sleeve; pin shafts are mounted in the adjustment sleeve; elastic retaining collars for shafts are arranged at the left and right ends of the pin shafts; the pin shafts are connected with sliding blocks; the sliding blocks are fixedly connected with pressing blocks through internal hexagonal bolts B; a drive box, a driven box and a gear box are mounted in a rack; a welding gun adjustment frame is fixed on the rack; the drive box is connected with the gear box; the gear box is connected with a motor; and manual clamping devices are respectively arranged on the drive box and the driven box. The anti-deformation welding machine special for the thin-wall cylinder can effectively reduce the thermal deformation amount of a welded piece.
Description
technical field [0001] The invention relates to a special welding machine, in particular to a special welding machine for preventing deformation of a thin-walled cylinder, which belongs to the technical field of mechanical welding. Background technique [0002] Aluminum and aluminum alloys have high strength, good corrosion resistance, electrical conductivity and thermal conductivity, and are widely used in industry. Aluminum has strong chemical activity. When it contacts with air, a dense Al2O3 film will be formed on the surface. Aluminum and The strong oxidation ability of its alloy will also hinder the welding between metals, which will bring certain difficulties to welding. The melting temperature of aluminum alloy is low, and the thin-walled aluminum alloy tube is easier to melt when welding, and the weld seam is difficult to form, and it is easy to produce cracks and pinches. Welding defects such as slag and pores, at the same time, the amount of deformation after weld...
