The invention discloses a double-
welding-gun automatic
heat pipe welder. The welder comprises a
machine frame, an automatic double-
pipe discharging device, an automatic double-
pipe feeding device, a double-
argon-arc-
welding-gun adjusting device, an automatic double-
pipe welding device and an automatic double-pipe falling device and a PLC, wherein an outer
branch pipe sliding table and a rubber wheel sliding table of the automatic double-pipe feeding device are installed on two linear guide rails through a pair of sliding blocks arranged in parallel respectively, an auxiliary
branch pipe fixing plate is arranged on one side of the outer
branch pipe sliding table, and two rubber wheel side plates are arranged on the two sides of the rubber wheel sliding table respectively; multiple parallel V-shaped grooves are formed in two
main branch pipe plates and three auxiliary branch pipe plates respectively in pairs, and the distance between two V-shaped grooves in each pair is equal to the distance between two material claw block clamping grooves. By the adoption of the welder, two heat pipes are welded at a time, the whole processes include conveying, feeding, welding and falling, two heat pipes are welded at the same time, efficient welding can be achieved, and various welding requirements can be met.
