The invention discloses a high-precision blanking die structure of a steel battery shell, and is applied to the production technology of thin-walled steel battery shells. The high-precision blanking die structure comprises an upper die holder plate and a punch workbench plate, wherein a blanking upper template and a stretch upper die fixing plate are arranged below the upper die holder plate, and a blanking upper die is arranged on the blanking upper die plate; a plurality of stretch punches which are arranged in parallel at intervals are arranged on the extension upper die fixing plate, and a blanking lower template and a stretch die, corresponding to the blanking upper template and the stretch punches, are arranged on the punch workbench plate; a blanking lower die is arranged on the blanking lower template, and a guide mechanism formed by a die holder guide sleeve and a die holder guide column is arranged between the upper die holder plate and the punch workbench plate; and an independent positioning guide assembly is arranged between the blanking upper template and lower templates. With the die structure, the matching precision of upper and lower dies is improved, and the die life is prolonged; and the assembly and disassembly are convenient, the maintenance time is shortened, and the efficiency of production is improved.
Description
Technical field [0001] The invention relates to a thin-wall battery shell production mold, in particular to a high-precision blanking mold structure for a battery steel shell. Background technique [0002] At present, thin-wall battery steel shells are generally stamped with progressive dies. See figure 1 As shown, figure 1 It is a schematic diagram of the structure of a traditional battery steel shell blanking die. It includes an upper die base plate 10 and a punch work table 11 corresponding to the upper die base plate 10, and blanking is installed under the upper die base plate 10 The upper mold plate 12 and the upper stretching mold fixing plate 13 are installed with a blanking upper mold on the blanking upper mold plate 12, and a plurality of stretching punches 14 arranged in parallel and spaced apart are sequentially arranged on the upper stretching mold fixing plate 13 , The punch work table 11 is provided with a blanking lower template 15 and a drawing die 16 correspondi...
