Zusammenfassung: | The invention relates to a cold stamping method of a conic part of an armored steel rotary body shell. The method comprises the following specific steps that firstly, preparatory work is done before cold stamping, whether a machined part belongs to the conic part of the rotary body thin shell or not is judged, and whether one-time cold stamping forming can be carried out or not is judged; secondly, a stamping blank is made, metal plate cutting is carried out according to the expanded view of the part, and the stamping blank is formed; and thirdly, cold stamping is carried out, the stamping blank is placed in a mold, a common oil pressure is adopted for stamping, two guide pins are adopted by the mold for guiding an upper mold and a lower mold, the cooperation relation of the guide pins with the upper mold and the lower mold is phi 100D9/f9, the maximum unilateral gap of guide is 0.147, and the minimum unilateral gap of guide is 0.06. According to the method, cold stamping processing ofa tempered high-strength |
