The combined water tank applying the composite flanging reinforcement, the triangular reinforcement piece 3 reinforcement and the rectangular reinforcement piece 3 reinforcement technology has the advantages that the combined water tank taking the stainless steel water tank with the length of 5 meters, the width of 4 meters and the height of 5 meters as an example has the volume of each die pressing block = the thickness of the plate, 1060 and 1060 in the prior art, and the volume of each composite flanging die pressing block 4 = the volume of the die pressing block plate plus the volume of the composite flanging plate in the prior art. The thickness of the bottom plate of the water tank is 2.0 mm, and the thickness of the top plate of the water tank is 0.5 mm. The prior art molded blocks were 1348320 cubic millimeters, 2247200 cubic millimeters 2080900 cubic millimeters, 3370800 cubic millimeters, and 4494400 cubic millimeters per block from side one layer to side 5 layers, respectively. Each layer of 18 blocks, totaling the 243749160 cubic millimeters of the volume of stainless steel sheet consumed by the prior art die press block. The bottom and top plates consume a volume of 50000000 cubic millimeters of the stainless steel material. The block volume of the composite flanging die pressing block 4 from the side 1 layer to the side 5 layer is 620800 cubic millimeters, 1210600 cubic millimeters, 1239600 cubic millimeters, 1268600 cubic millimeters and 1856400 cubic millimeters respectively. The volume of the stainless steel material consumed by the composite hemming die pressing block 4 in the technology is 111528000 cubic millimeters. The material volume of the side face composite flanging die pressing block 4 in the technology is only 45 percent and 75 percent of the material volume of the die pressing block in the prior art, and the material consumption in the technology is only 55 percent of the material volume in the prior art from the whole water tank. Because the total folding thickness of the composite folding die pressing block 4 is greater than the thickness of the die pressing block in the prior art, and the technical reinforcing measure is adopted, the moment of the expansion pressure of the liquid in the box body to the folding edge of the die pressing block is shortened, the bending deformation resistance strength of the folding edge is obviously enhanced, and the service life is greatly prolonged.
