The invention discloses a novel automatic flame welding machine, comprising a frame, a workpiece fixture arranged in the frame, a three-DOF (degree of freedom) shifting mechanism arranged on the frame, and a welding flame bar disposed on the three-DOF shifting mechanism, wherein the welding flame bar is positioned above the workpiece fixture and includes a plurality of vertically arranged welding flame nozzles, and the lower end of each welding flame nozzle is provided with a transverse flame spout. According to the novel automatic flame welding machine, flames are moved from top to bottom to approach weld of a workpiece to be processed in order to carry out welding at the premise that the relative position of the flame nozzles and the workpiece to be processed is precisely determined; the welding problem of a heat exchanger with retaining plates can be effectively solved, and welding quality and welding efficacy are effectively improved; the novel automatic flame welding machine is convenient to control, has low requirement on operating personnel, and has good economic and social benefits.
Description
technical field [0001] The invention relates to a flame welding machine, which belongs to the technical field of welding equipment, in particular to a novel automatic flame welding machine and a welding method thereof. Background technique [0002] Air conditioners have been widely used in daily life, and their core components, copper tube heat exchangers, are in great demand. At present, the gas flame welding technology is used for the welding of the U-tube part of the air-conditioning heat exchanger. In the prior art, the gas flame welding technology generally adopts the horizontal flame gas welding method, and the horizontal movement method is adopted when the torch approaches the welding spot of the workpiece, but there are also the following insurmountable defects in practical applications, for example, for It is not suitable for heat exchangers with baffles on the side, because the baffles of the heat exchanger will block the horizontally sprayed flames, which must be...
