Technical Field
[0001] This utility model belongs to the field of steel can processing and manufacturing, and specifically relates to a welding and fixing device for cans. Background Technology
[0002] Steel carrying cans are sturdy metal containers with reinforcing ribs and handles. They can be widely used to hold oils and package chemical products, petroleum, paints, food, etc.
[0003] The main raw materials for manufacturing steel portable cans include cold-rolled steel plates, hot-rolled steel plates, tin-plated steel plates, and chrome-plated steel plates. The inner wall of the can is coated with epoxy resin, phenolic resin, or similar coatings, while the exterior is painted. During the manufacturing process, the steel plates are first uncoiled and leveled: the coiled steel plate is unfolded and leveled; then, it is sheared / punched: a large stamping press is used to punch the steel plate into blanks for manufacturing the can body, bottom, and lid. The can body blanks are then rolled into rectangles and welded together. Finally, the bottom and lid are welded to both ends of the can body for fixation.
[0004] Currently, when welding and fixing the two ends of the steel portable can to the bottom and lid, the can body is usually pressed down and fixed manually, and then the bottom and lid are manually joined to the can body for welding. The disadvantages are that it is not convenient to operate, affects the welding efficiency, and the operator needs to operate with both hands at the same time, which can easily lead to a decrease in processing accuracy.
