The left and right side panel forming line of the refrigerator is a fully automatic production line. This molding line is used for the integrated production molding of the left and right side panels of refrigerators. It mainly consists of a feeding machine, a punching machine, a 180 degree flipping machine, a rolling mill, a cutting machine, a two end step bending machine, a 90 degree bending machine, an edge wrapping machine, a machine, and supporting pneumatic system, hydraulic system, electronic control system, etc. This line is not only used for the production of double-sided panels, but also has the function of producing one type of side panel separately. According to product requirements, each specialized machine can be freely combined to complete automatic feeding, punching and edge cutting, sheet flipping, roll forming, cutting, step forming, bending at both ends, cutting and other processes for fixed length sheet metal. This production line has the advantages of reasonable process layout, high production efficiency, good automation level, safe and reliable human-machine interface operation, convenient maintenance, and adaptability to a wide range of products.
