Description

Technical Field

[0001] The invention relates to the technical field of oil boiling barrel processing, in particular to an anti-stripping welding device for oil boiling barrel processing and an operating method thereof. Background Art

[0002] As a key equipment in the field of oil processing, the oil boiling barrel is widely used in scenarios such as oil refining and chemical raw material preparation in the food industry. Its core function is to achieve efficient melting, extraction and refining of solid oil raw materials through the synergy of a precise temperature control system and a mechanical stirring device. This type of container is usually formed by rolling carbon steel or stainless steel sheets. The quality of the longitudinal seam welding of the cylinder directly affects the pressure-bearing performance and safety of use of the equipment. In the container manufacturing process, the longitudinal seam welding process is generally implemented using a roller seam welder. This equipment dynamically pressurizes the seams of metal sheets through upper and lower copper alloy roller electrodes, and uses the resistance heat effect generated when the welding current passes through the contact interface to make the metal in the area to be welded instantly reach a plastic state and form a metallurgical bond. This continuous roller spot welding process ensures that the weld has a dense fish-scale structure with good air tightness and mechanical strength.

[0003] However, the traditional operation mode has significant ergonomic defects: the operator needs to manually maintain the alignment of the rolled metal tube and the welding machine roller throughout the process, and realize the welding process through continuous traction. This process places extremely high demands on the operator's spatial positioning ability, operational stability and continuous concentration. The metal tube is easy to spread apart during the welding process, and quality defects such as weld offset and lack of fusion due to human factors often occur in production, which may indirectly increase the risk of desoldering due to stress concentration and indirectly cause desoldering due to insufficient strength. This work mode that is highly dependent on experience not only restricts production efficiency, but also easily causes operator fatigue due to long-term high-intensity and focused work, posing a safety hazard. Summary of the Invention
