Metal can body forming processing method

Abstract

The invention relates to a metal can body forming processing method which adopts a following metal can body forming processing device. The metal can body forming processing device comprises a base, afeeding mechanism, a supporting mechanism, a stamping lower die mechanism, a driving mechanism, a conveying mechanism, a stamping upper die mechanism and a waste box, wherein the feeding mechanism isarranged at the front side of the upper end face of the base; the supporting mechanism is arranged on the upper end face of the base and located at the rear side of the feeding mechanism; the stampinglower die mechanism is arranged in the middle of the supporting mechanism in a sliding fit mode; the driving mechanism is arranged at the lower end of the stamping lower die mechanism; the conveyingmechanism is arranged on the upper end face of the base and located at the right side of the driving mechanism; the stamping upper die mechanism is arranged at the upper end of the supporting mechanism; and the waste box is arranged on the upper end face of the base and located at the rear side of the supporting mechanism. According to the metal can body forming processing method, the problems oflow efficiency and the like when a stamping die is disassembled and replaced in the process of manufacturing a two-piece can by using a punch press through stretching a forming die can be solved.

Description

technical field [0001] The invention relates to the field of metal manufacturing, in particular to a method for forming and processing a metal tank body. Background technique [0002] In daily life, you can often see a can-shaped packaging box made of some metal. The metal cans are mainly classified into three-piece cans and two-piece cans according to the manufacturing method, and the two-piece cans came out in the middle of the 20th century. The entire packaging can is composed of two pieces, namely the can body and the can lid, so it is called a two-piece can. [0003] The can body of the two-piece can is a thin metal plate, which is stretched and deformed by a punch through a stretching mold, so that the bottom and body of the tank are connected into one. The following problems usually exist when processing two-piece cans in the prior art: Due to the variety of shapes of metal cans, when manufacturing cans of different shapes, it is necessary to frequently disassemble t...

Problems solved by technology

[0003] The can body of the two-piece can is a thin metal plate, which is stretched and deformed by a punch through a stretching mold, so that the bottom and body of the tank are connected into one. The following problems usually exist when processing two-piece cans in the prior art: Due to the variety of shapes of metal cans, when manufacturing cans of different shapes, it is necessary to frequently disassemble the upper and lower molds on the punching machine, and it takes a long time to disassemble and replace the molds, thereby reducing the production efficiency of two-piece cans; And the stamping die is heavy because of its heavy weight, so when disassembling and replacing it, it is easy to cause the die to fall and hurt people because the person who replaces the die cannot hold the stamping die firmly. There are safety hazards for personnel who change molds

[0004] Regarding the technical problems existing in the current process of manufacturing two-piece cans with a punching machine through a stretch forming mold, personnel in the related technical field have made research and made adaptation improvements, such as the Chinese invention patent No. 2019103703088 A metal The can manufacturing process can produce metal cans with novel shapes, but the above-mentioned problems are not mentioned
