Description

technical field [0001] The invention relates to a welding device, in particular to a numerical control radiator automatic welding machine. Background technique [0002] With the progress of society, there is a further understanding of environmental pollution and energy consumption. Casting radiators consume a lot of energy and cause serious pollution. In order to save energy and reduce emissions, the country is now vigorously promoting steel radiators. Steel radiators have a beautiful appearance and can be made into various shapes, but the difficulty of processing increases and the quality of the weld joints is difficult to guarantee. The existing special-purpose welding equipment for one-time forming is only resistance welding, although the resistance welding equipment is efficient. , but the power is 250KW, which requires a high load on the power grid and requires a super-high-power transformer to support it.

Problems solved by technology

Steel radiators have a beautiful appearance and can be made into various shapes, but the difficulty of processing increases and the quality of the weld joints is difficult to guarantee. The existing special-purpose welding equipment for one-time forming is only resistance welding, although the resistance welding equipment is efficient. , but the power is 250KW, which requires a high load on the power grid and requires a super-high-power transformer to support it. When the resistance welding equipment is started, it interferes a lot with other electrical equipment, causing unstable operation of other peripheral equipment and affecting the processing technology of the workpiece. The requirements are extremely high, and if there is a slight deviation in the welding joint of the workpiece, there will be missing welding, and the defective rate is high

Therefore, the steel radiator processing factories now mainly use manual welding. Manual welding requires high welding level of personnel. Working in a high temperature environment, the work intensity of the workers is relatively high, which may easily cause fatigue of the welding personnel, and the product quality cannot be guaranteed. The output of a single shift is about 120 columns per person in 8 hours, the production efficiency is low, and the cost remains high
