The specific embodiment:
Production process of stainless steel wheel for motor vehicle comprises the process that press-fits of the course of processing of wheel rim and spoke and the two.The course of processing of wheel rim is: blanking → volume circle → butt welding → scrape slag → enlarging → one time roll-forming → secondary roll-forming → expanding → valve hole → polishing → surface treatment → to pressing assembly; The spoke course of processing can adopt Sheet Metal Forming Technology or spinning process, and the Sheet Metal Forming Technology of spoke is: blanking → one-shot forming → post forming → three time moulding → connection dashes → squeezes screw → towards breather port → squeeze breather port → machinework → surface treatment → to pressing assembly; The spinning process of spoke is: blanking → spin forming → connection dashes → squeezes screw → towards breather port → squeeze breather port → machinework → surface treatment → to pressing assembly; At pressing assembly wheel rim and spoke are welded as wheel set.Because corrosion-resistant steel is lower than carbon structural steel superficial hardness, in the course of processing and transport process, cause easily and scratch and collide with, this brings difficulty can for the polishing of final workpiece, influence surface quality of products, thereby require the per pass operation all to take appropriate measures to guarantee the surface quality of workpiece, the scuffing of stopping to collide with, take following measure: the roller at wheel rim volume sired results ordered pair furling plate round machine carries out the surface sand-blasting processing for this reason, make volume circle roller surface finer and smoother, promptly guarantee the required friction force of volume circle, guaranteed the surface quality of workpiece again; Wheel rim enlarging operation is the easiest operation that causes scuffing, existing enlarging process mould adopts two cones, there are Frictional Slipping in cone and workpiece during enlarging, produce very big friction force, directly affect product design, even it is also of no avail with the change roughness to improve die surface hardness, after engineer testing adopts the enlarging of expanding formula, problem is satisfactorily resolved; Wheel rim roll-forming operation also is to be easy to generate the operation that workpiece scratches, the way that solves is to adopt the Cr12 alloy die steel through laser hardening, laser transformation hardening, the pair roller wheel surface carries out ground finish in addition, improve the hardness on running roller surface and reduced roughness of surface, adopt the external hydraulic-driven roller pressing forming machine of introducing in addition, roller pressing forming machine two main shafts are adjusted automatically, guaranteed two running roller linear velocity unanimities, avoid the friction of roll-forming process middle roll and workpiece that workpiece is formed scuffing; Other operation and spoke stamping, spinning operation to wheel rim are also taked corresponding measure, accomplish that the work piece production process does not roll off the production line, and transform the raceway and the transhipment working position apparatus of manufacturing line.Corrosion-resistant steel has higher mechanical strength than common material, and resistance of deformation is bigger by 20% than common material in the process of roll-forming, punch forming, spin forming, and corresponding forming force also strengthens 20%; Corrosion-resistant steel has bigger springback capacity man-hour adding, and takes corresponding measure reducing and compensate resilience on mold design and technological parameter are determined, modulus of resilience presses 0.15% during the design of expanding mould.Corrosion-resistant steel has higher work hardening characteristic, inter process in repeatedly moulding very easily produces work hardening, when serious even cause be full of cracks, whether rationally be key of success, should rationally arrange technology and definite technological parameter if handling in the technological design, reduce to process number of times as far as possible, control rational work hardening capacity, reduce shaping expanding amount as far as possible during design wheel rim technology and avoid the expanding cracking, generally be controlled at about 5mm, avoid roll compacting excessively in the roll-forming process; Corrosion-resistant steel compares permeability of heat with carbon structural steel and electric conductivity is relatively poor, fusion temperature is low, heat is slower to the periphery diffusion in the welding process, require the secondary non-load voltage of welding machine to want high when therefore welding, require flash of light stable violent in the welding process, the time is 5～6 seconds, requires welding machine to have bigger upset force, increase 15% than ordinary steel, to produce enough plastic deformation at weld zone.Be to reduce the oxidation of high-temperature metal in the weld bond, begin, finish the flash of light process with maximum flashing speed with the flashing speed of minimum.Because the stainless steel hot conductance is little, the line expansion factor is big, under patterned heat and cooling condition, welded joint may form bigger tensile stress in cooling process, corrosion-resistant steel easily forms the very strong column crystal seam organization of directivity simultaneously, has impelled the segregation of impurity such as S, P, form the interdendritic liquid interlayer, therefore cause thermal crack easily, select low power welding conditions and welding speed faster when adopting submerged arc-welding, on solder flux is selected, select of the generation of SJ601 sintered flux for use with the minimizing thermal crack.The corrosion-resistant steel wheel has been cancelled the pickling and the painting process of material in the steel car wheel production process, no acid solution, waste water and discharge of harmful gases.The appearance of corrosion-resistant steel wheel depends on polishing process and surface treatment, adopts glossing or other surface polishing and electrochemical treatment technology, makes wheel surface reach pure and fresh bright and clean, luxurious beautiful impression.
