A metal square can body forming mold

Abstract

The invention discloses an iron square tank body forming die. An upper die body comprises an outer die drive wedge, an inner die drive wedge and a rolling template; a lower die body comprises a shaping inner die body, an edge turning inner die body, a shaping outer die body and an edge turning inner die drive wedge; the edge turning inner die body is arranged below the shaping inner die body, the edge turning inner die drive wedge is arranged in a hole in the middle of the shaping inner die body, a punching element is arranged outside the shaping inner die body in a sleeved mode, when the upper die body moves downwards, the outer die drive wedge drives the shaping outer die body to retract inwards, meanwhile, the inner die drive wedge drives the shaping inner die body to expand outwards, and shaping of the punching element and protruding ribbing of the upper portion of the punching element are finished; the upper die body continues to move downwards, an upper opening of the punching element enters a rolling annular groove in the bottom face of the rolling template, and rolling of the upper opening of the punching element is finished; in the last stroke that the upper die body moves downwards, the inner die drive wedge presses the edge turning inner die drive wedge downwards, the edge turning inner die drive wedge drives the edge turning inner die body to expand outwards, and outwards turning of a lower opening of the punching element is finished. According to the iron square tank body forming die, an iron square tank body can be manufactured once, production efficiency is high and production cost is low.

Description

[technical field] [0001] The invention relates to a stamping die, in particular to a metal square can body forming die. [Background technique] [0002] Forming the body of a tin square can requires four steps, namely shaping, rib forming, upper mouth rounding, and lower mouth eversion. Traditional operations require a mold and a piece of equipment for each step, resulting in low productivity and high production costs. [Content of the invention] [0003] The technical problem to be solved by the present invention is to provide a metal square can body forming mold that can complete shaping, protruding rib forming, upper mouth rounding, and lower mouth eversion on one piece of equipment, so as to improve production efficiency and reduce production cost. cost. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is that a metal square can body forming mold includes an upper mold and a lower mold, the lower ...
