Description

Technical Field

[0001] The invention belongs to the technical field of refrigeration accessories processing, and particularly relates to a flame welding tool for processing air-conditioning condenser pipes. Background Art

[0002] Flame welding tooling performs multiple critical functions in the processing of air conditioner condenser tubes. First, through precise positioning and clamping, it ensures the precision of the copper or aluminum tube joints, preventing dimensional deviations caused by thermal deformation and thus ensuring the tightness of the welded joint. Second, the tooling's flame control system adjusts the ratio of oxygen and fuel gas to optimize the welding temperature, ensuring uniform flow of the molten metal pool and minimizing oxidation and slag inclusion defects. For thin-walled condenser tubes, the tooling also uses segmented heating or preheating to prevent perforation caused by localized overheating. On automated production lines, flame welding tooling is linked to robotic arms or conveyors for continuous operation. Furthermore, some high-end tooling is equipped with infrared temperature measurement modules, providing real-time temperature feedback and adjusting flame parameters to further enhance process stability. From a quality control perspective, the design of welding tooling must comply with industry standards. Its structural strength, corrosion resistance, and ease of cleanability directly impact the hygiene and safety of the production environment. Through standardized operating procedures, the tooling also reduces weld spatter and fume pollution, meeting environmental requirements. Therefore, flame welding tooling is not only a technical tool but also a core equipment for air conditioner manufacturers to enhance product competitiveness and reduce rework rates.

[0003] Traditional flame welding tooling used for processing air conditioner condenser tubes has shortcomings. First, the flame welding head cannot rotate around the butt joint seam. The butt joint condenser tube must be rotated, which can easily cause the butt joint seam to misalign, affecting the welding effect. Second, the tooling cannot quickly cool the condenser tube after welding. Furthermore, spattered welding slag will deposit on the tooling surface, requiring additional cleaning and maintenance, significantly increasing the workload. Therefore, optimization and improvement are needed. Summary of the Invention
