Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and relates to a turnover flame welding tooling. Background Art

[0002] With the rapid development of the automotive industry, the automotive air conditioning system has become an important part of vehicle comfort. As the core part of the air conditioning system, the performance of the automotive heating system directly affects the comfort of driving and riding. In order to improve the performance of the automotive heating system, the manufacturing quality requirements for its core component, the heater core, are getting higher and higher.

[0003] Traditional manual flame welding methods have obvious deficiencies in terms of production efficiency and product quality. First of all, manual welding depends on the skills and experience of welders, and it is difficult to ensure the consistency of welding quality. Since parameters such as temperature and time during the welding process are difficult to accurately control, it is easy to cause welding defects, such as incomplete welds and cracks. Secondly, the production efficiency of manual welding is low and cannot meet the needs of large-scale production. Each welder can only complete a limited number of welding tasks per day, and it is difficult to increase the welding speed. In addition, long-term manual welding will cause harm to the welder's body, such as eye fatigue and respiratory diseases, increasing the labor intensity.

[0004] To solve these problems, some automatic or semi-automatic welding equipment has emerged in recent years, such as resistance welding machines and laser welding machines. Although these equipment improve the welding efficiency, there are still certain limitations. For example, resistance welding machines are mainly suitable for welding thin plate materials, and the welding effect on thick plate materials is not good. Although laser welding machines have high welding quality, the equipment cost is high, and the technical requirements for operators are also high. Therefore, developing a welding equipment with high efficiency, precision and moderate cost to meet the needs of automotive heater core manufacturing has become an urgent problem to be solved.
