Double-welding-gun automatic heat pipe welder

Abstract

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.

Description

technical field [0001] The invention relates to a welding device, in particular to a heat pipe automatic welding machine with double welding torches, which is used for automatic welding of both ends of the heat pipe. Background technique [0002] The heat pipe has high heat conduction performance, and the application of the heat pipe can significantly improve the heat dissipation efficiency of the radiator. In the manufacture of the heat pipe, its two ends need to be welded, and the welded area is required to be reliable and beautiful. Manual welding has a large workload, low efficiency, poor reliability, and difficult to guarantee consistency, while the general single-tube automatic welding equipment is not efficient, because a more efficient and reliable welding equipment is needed.

Manual welding has a large workload, low efficiency, poor reliability, and difficult to guarantee consistency, while the general single-tube automatic welding equipment is not efficient, because a more efficient and reliable welding equipment is needed.

[0003] The Chinese invention patent application CN104148784A (public date 2014.11.19) previously applied by the applicant discloses an automatic ultra-short heat pipe welding machine, including a frame, an automatic pipe discharge hopper device, an automatic material pushing device, an automatic heat pipe positioning device, and an argon arc welding machine. Welding torch adjustment device, automatic welding device, automatic falling ramp device and PLC; the rubber wheel of the automatic welding device is divided into a driving wheel and a driven wheel, and the parallel gap between the driving wheel and the driven wheel is set; the parallel gap between the two rubber wheels and auxiliary wheels is set, and the gap One end communicates with the V-shaped groove, and the other end communicates with the gap between the driving wheel and the driven wheel; the synchronous pulley is coaxially installed with the driving wheel; the synchronous pulley is connected with the stepless speed regulating motor through the belt; the graphite wheel is worn on the pressure rod, The two ends of the pressure rod are respectively connected with two guide rods; the guide rod is inserted into the linear bearing to form a sliding pair, the two linear bearings are locked on the pressure plate, and the pressure plate is connected to the compression cylinder; the invention can adapt to welding of different pipe lengths and diameters and Automatic welding of ultra-short heat pipes can be realized; however, the equipment can only weld one heat pipe at a time, and the welding efficiency needs to be further improved
