Stretch forming process of stainless steel water tank: The machine generally uses a large-tonnage hydraulic press (200T) to stretch the plate; the mold angle cannot be too straight, generally directly above φ10, and the structure must be reasonable; the material generally requires a plate thickness range of 0.8 Within -1.0mm; the overall stretched water tank generally requires high temperature annealing treatment, generally at a temperature above 1200 degrees, to eliminate the internal stress after stretching; the surface is generally brushed, polished, and polished (usually smooth); After the sheet is added with mold drawing oil, it can be stretched smoothly, annealed after forming, and then surface treated.
Manual forming process of stainless steel sink: the machine generally uses bending machine, hydraulic press to form, and argon arc welding machine to weld; fixture uses bending fixture and hydraulic press mold; because the process adopts bending, there is not much restriction on the thickness of the plate, generally according to the economic Use a reasonable thickness; according to the thickness of the material, different welding currents can be selected, for example, the welding current below 220A is used for 1.2mm; the surface treatment generally uses wire drawing, grinding, polishing (usually smooth surface), etc.; in terms of technology, the plate is generally bent first. Forming, like an origami box, welding the side seams, and finally surface treatment.
