Abstract
A method for producing an aerosol dome with a dome region including a rolled edge, which adjoins the upper face and which is arranged on an upper through-opening, and including a flange region, which adjoins the lower face and has a folded-over section. An intermediate stage is provided from a paint-coated blank in one or multiple stages, the intermediate stage having the upper through-opening that is followed downwards by a neck section and further by the dome region, which is followed by a straight circumferential flange, and the intermediate stage is processed in a processing stage, in which solely the folded-over section is formed.
Claims25
A method for producing an aerosol dome having a dome region with a rolled rim which adjoins the upper side and is arranged along an upper through-opening and having a flange region with a fold which adjoins the lower side,
- wherein an intermediate stage is prepared from a paint-coated or polymer-coated blank in one or more stages, which intermediate stage has a base, downwardly followed by a neck portion and further followed by the dome region, which is followed by a straight circumferential flange,
- wherein this intermediate stage is machined in a machining stage, in which at least the fold is formed,
- and wherein, in the machining stage before the forming process, the intermediate stage bears with the straight circumferential flange on at least three lifting pins without contacting a push-in sleeve,
- the component is then guided with its base onto a waste drawing die, advancing from below, by a pressure sleeve,
- the lifting pins are then moved away and the component lies with the straight circumferential flange exposed,
- the fold is then formed,
- and the component with the fold is then lifted to the transportation level from below at the fold by the push-in sleeve for transportation into a subsequent machining station.
