Description

Technical Field

[0001] The utility model relates to the field of induction heating welding assembly equipment, in particular to an automatic pipe fitting welding device. Background Art

[0002] Induction heating welding is a method that uses induction heating technology to achieve heat source, generate current and heat on the workpiece, and complete the welding process. Compared with traditional welding technology, induction heating welding has the advantages of fast welding, energy saving and environmental protection, and precise welding, and is widely used in the welding process of various workpieces.

[0003] For welding between pipe fittings and other connecting parts, when induction heating is used for welding, the workpiece to be welded is first fixed, the pipe fitting corresponds to the top of the connecting part, the induction coil is sleeved on the outer circumference of the pipe fitting, and moves from top to bottom until it reaches the welding position. At the welding position, current is connected in the induction coil to achieve welding. However, for some special-shaped pipe fittings, there are structures protruding outward on the outer circumference of the pipe fitting. Using an induction coil from top to bottom will interfere with the protruding structure of the pipe fitting. If the diameter of the induction coil is increased to avoid the protruding structure, the distance between the induction coil and the welding position is far, and the welding effect is not good. Therefore, it is necessary to produce an automated pipe welding equipment to solve the above-mentioned problems. Utility Model Content
