The snap-fit ​​design makes the disassembly and maintenance of the barrel cover and the barrel body more convenient, and is easy to clean and inspect.

[0043] Steps S1-S3 reduce production time and cost and improve overall production efficiency through optimized production process, including water swelling, laser cutting, cleaning and drying, spot welding, full welding and other steps. The use of technologies such as laser welding and spot welding ensures a firm connection between the various components of the insulation barrel, improving the durability and service life of the product. Through measures such as vacuuming and using a vacuum layer, the influence of external temperature is effectively isolated, significantly improving the insulation effect of the insulation barrel. Steps such as cleaning and drying ensure the cleanliness of the insulation barrel, avoid food contamination, and ensure food safety.

[0044] Preferably, in the above-mentioned production process of a special-shaped stainless steel vacuum insulation barrel, in step S1, temperature measurement is also included between vacuuming and grinding, and temperature measurement is also included after welding the rotating clamp. In step S2, temperature measurement is also included between vacuuming and electrolysis, and temperature measurement is also included before welding the fastening clamp strip.

[0045] Temperature measurement is used to judge the vacuum performance, using the principle of internal heating and heat transfer to determine the impact of the production process on the vacuum.

[0047] By conducting full inspections between key production steps, defects or deviations in the production process can be discovered and corrected in a timely manner to ensure the high quality of the final product. As part of the production process, full inspections help to discover problems in the production process in a timely manner and promote continuous optimization of the production process. By discovering problems during the production stage, the need for rework in the later stage can be reduced, reducing rework costs.

[0048] Preferably, in the production process of the above-mentioned special-shaped stainless steel vacuum insulation barrel, welding is performed by laser welding.

[0049] Laser welding can achieve high-precision welding trajectory, ensure the accuracy of welding position, and improve welding quality. : Laser welding has high connection strength, which improves the structural stability of the insulation barrel. Laser welding has good sealing and can effectively prevent gas leakage. The heat-affected zone of laser welding is small, which reduces thermal damage to the material and maintains the original performance of the material. Laser welding has high speed and high degree of automation, which can significantly improve production efficiency. The weld quality of laser welding is high, which reduces the workload of subsequent grinding and finishing, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
