| This work aims to analyze the forming law of box parts and solve the problem of box forming. Major parameters like blank unfolding material, number of drawing, selection of blank holder and die and the specifications of punch required by drawing process were calculated to formulate a machining process plan. Problems like crinkle, scratch and breakage in drawing were analyzed so that proper lubricant could be adopted. With a typical box as an example, the trial processing was carried out. Part size was 100% qualified and part surface had good quality. In conclusion, the calculation principles of technological parameters and the selection of lubricant can guarantee the dimension precision and surface quality of box parts and improve production efficiency. This method has certain reference value for the calculation and analysis of the technology of similar parts. |
