Embodiment Construction

[0013] An automatic welding equipment for thin plate fillet welds, see figure 1 , figure 2 : Used for parallel welding operations where the welding seam is located at the 90° angle between the folded edge of the thin plate and the edge of the thin plate. It includes two structures, characterized in that the equipment structure of the long side of the welding angle is that the bottom plate 2a is fixed on the horizontal surface of the bracket 1a. The two ends of the bottom plate 2a are respectively fixed with the motor 10 and the two gears 11. The bottom plate 2a is equipped with a slide rail 3 and a sliding block 4, and the sliding block 4 is connected with an adjusting mechanism 5. The adjusting mechanism 5 is installed on the inclined plane of the welding gun 6 and the weldment assembly. The weldment has a 30° contact line; the weldment sheet is placed between the bottom plate 2a and the lining plate 8, and then a thin plate 2 is placed on the lining plate 8, and finally the pr...

Abstract

The invention relates to automatic welding equipment for a fillet weld of sheets, which is used for welding two structures with an included angle of 90 degrees. The automatic welding equipment is characterized in that in a fillet long-side structure I, a base plate is fixed on the horizontal plane of a support, a motor, a sliding rail, a slide block and a regulating mechanism for connection are installed on the base plate, a 30-degree gradient contact line is formed between a welding gun aslant installed on the regulating mechanism and a weldment heat exchange sheet on a middle horizontal plane, a weldment assembly supports the space to be welded of the heat exchange sheet, the base plate and two long ends of a press plate are clamped by nuts, the entire weldment assembly is laterally fixed by a lining board bolt, and the motor and an argon arc welding gun are started to automatically complete welding operation. A fillet wide-side structure II is characterized in that: a support for fillet wide-side welding is separated from a weldment base, the high side of a triangular support is fixed with the vertical face of an outer frame, and a bedplate is additionally arranged. The automatic welding equipment provided by the invention has the advantages that: the requirements on the strength and appearance quality of the welded seam and the flatness and verticality of the sheets can besatisfied; the characteristics of excellent formed welded seam, time / labor-saving performance, low labor intensity and high welding efficiency are achieved; and the operation is simple and convenientand the reliability is high.

Description

Technical field [0001] The invention relates to metal processing, an automatic welding equipment for welding thin plates and thin plates at an angle of 90°. Background technique [0002] At present, heat exchange fins welded with thin plates have become the main heat exchange elements for heat exchange on plate heat exchangers. The existing automatic welding equipment does not have equipment for right-angle welding of thin plates. The problem to be solved is to fold the two sheets with a thickness of 1.2mm, and then weld the flanged end face and the edge of the unfolded sheet at a 90° angle to each other to form a set of rectangles in the heat exchanger where the channels cross each other at 90° Body heat exchange fins. The technical difficulty is that the thin plate itself is prone to wave deformation due to heat at the edges during welding. The hemming height is only 12mm, so the hemming space is small, and it is difficult to fix it. In addition, it is necessary to ensure t...
