Full-automatic high-speed manufacturing method and full-automatic high-speed manufacturing device of metal packaging tank body

Abstract

The invention discloses a full-automatic high-speed manufacturing method and a full-automatic high-speed manufacturing device of a metal packaging tank body and aims to solve the defects that machining requires many devices, automation degree is poor, operation efficiency is low, manufacturing cost stays at a high level and manufacturing quality is not high in the prior art. The technical scheme is characterized in that during automatic gradual conveying, the bottom opening edge of the metal tank body is rolled and flanged automatically in a first workstation, so that the opening edge can flange outwards, a metal tank bottom plate is additionally mounted at the bottom opening of the metal tank automatically in a second workstation to obtain the metal tank body, and the metal tank is overturned automatically in a third workstation, so that the tank bottom faces downwards and the opening faces upwards; the tank wall of the metal tank body is expanded automatically in a fourth workstation to be inclined outwards, the top opening edge of the metal tank body is automatically rolled and flanged in a fifth workstation, the top opening edge is overturned outwards, limit rings are automatically machined and stacked on the upper portion of the metal tank body automatically in a sixth workstation, the top opening edge of the metal tank body is outwards flanged, and accordingly, the manufacturing of the metal tank body is completed.

Description

technical field [0001] The invention relates to a metal packaging can production method and equipment thereof, in particular to a fully automatic high-speed production method and equipment for a metal packaging can body without welded handle ears. Background technique [0002] The currently commonly used metal packaging can body without welding handle ears becomes a complete uncapped metal packaging can after welding the handle ears and installing the handle. The can body of this kind of metal packaging can is generally made of tinplate sheet, and then the bottom of the can and the edge of the top are added. It is generally required that metal packaging cans can be nested into a stack on empty cans to save storage space, so the tank wall of metal packaging cans generally needs to have a certain inclination that expands upwards and outwards, and at the same time, there is generally a circle on the upper part of the tank wall Convex telescoping limit ring. At present, the me...

Problems solved by technology

[0003] In order to overcome the existing method of similar metal packaging cans, various equipments are required to process separately, and some links need to be manually operated, resulting in poor automation, low operating efficiency, unreduced production costs, and low production quality. At present, there is no such method. Ideally, a single machine can be used to complete the full-automatic high-speed production method of the metal packaging can body at one time and the defects of the equipment available for use. The purpose of the present invention is to provide an improved fully automatic high-speed production method of the metal packaging can body and its equipment can overcome the defects of the prior art
