Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline welding technical field especially is related to a double position high frequency welding machine for air conditioner pipeline piece welding. BACKGROUND

[0002] In the manufacturing process of air conditioner pipeline piece, welding is a crucial link. The traditional single station welding machine has many shortcomings, such as inaccurate positioning, low efficiency and coil burning, etc. These problems seriously restrict the production efficiency and product quality. In order to overcome these defects, a double station high frequency welding machine for air conditioner pipeline piece welding is born.

[0003] The working principle of high frequency welding machine is mainly based on high frequency electromagnetic induction heating. In the welding process, high frequency current passes through the induction coil to generate a strong magnetic field. The magnetic field generates eddy current inside the welded workpiece. The eddy current generates heat when flowing in the workpiece, so that the workpiece is locally rapidly heated to the molten state, realizing welding. High frequency welding has the advantages of fast welding speed, high welding quality and small heat affected zone, and is especially suitable for welding of thin-walled and precision parts such as air conditioner pipeline parts.

[0004] The single station welding machine often relies on manual operation in workpiece positioning, which not only increases the operation difficulty, but also easily leads to inaccurate positioning, thereby affecting the welding quality and production efficiency. The single station welding machine can only weld one workpiece at a time, which cannot fully utilize the production time, resulting in low production efficiency.

[0005] In the high frequency welding process, the induction coil will generate a lot of heat. If it cannot be cooled in time, the coil temperature will rise, and even burn out. The existing single station welding machine often lacks effective cooling system, which cannot cool the induction coil in time, thereby increasing the risk of coil burning. Coil burning will not only affect the welding quality, but also increase the production cost and maintenance difficulty. INVENTION CONTENTS
