Curling Tool Assembly Modular Adjustment for Metal Shells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing curling tool assemblies require complex stacking and adjustment of multiple levels, making it difficult to change or adjust curling tools for different shell sizes, especially at the bottom and middle levels.
Innovation Solution
A curling tool assembly with outer curler segments coupled to a shell support member, featuring a flange with apertures for an adjustment screw and fasteners, allowing easy coupling, removal, and adjustment of the segments, along with an inner curler segment opposing the outer segment to define a lip curling station, facilitating the curling of metal shells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple levels of curling tools are stacked one on top of another, then the number of curling units required is reduced, but the difficulty of adjusting and changing curling tools increases
Solution Approach 1:
The curling tool assembly is divided into modular components: shell support members with flanges that can be independently positioned, outer curler segments that can be removed and replaced, and adjustment screws that individually control each segment. This segmentation allows tools at different levels to be adjusted or changed independently without affecting other levels, resolving the contradiction between reducing unit数量 and maintaining ease of operation.
2Area of stationary object
If curling tools are arranged in a stacked configuration, then space utilization is improved, but accessibility to bottom and middle level tools deteriorates
Solution Approach 1:
The flange structure acts as an intermediary component that provides a standardized interface between the shell support member and the curler segments. This intermediary design with standardized apertures and fastening mechanisms enables easy attachment and detachment of curler segments at any level, including bottom and middle levels, without requiring disassembly of the entire stacked structure.
3Productivity
If complex stacking arrangements are used to reduce curling unit数量, then device complexity increases, but the number of required units decreases
Solution Approach 1:
The shell support members with flanges and adjustment screws serve multiple functions: they provide structural support, enable positioning adjustment, allow segment replacement, and facilitate maintenance. This multi-functionality reduces the need for specialized components at each level, simplifying the overall stacking arrangement while maintaining the ability to operate multiple curling tools in one unit.

AI summary
The invention generally relates to a curling assembly for curling metal shells. The curling assembly has a shell support member having a flange extending from a foundation of the shell support member with the flange having a first aperture and a second aperture passing through the flange. An outer curler segment is coupled to the shell support member. An adjustment screw passes through the first aperture of the flange with the adjustment screw being structured to engage the outer curler segment. Actuation of the adjustment screw would position the outer curler segment. The second aperture of the flange is structured to receive a fastener for coupling the shell support member to a base of a curling unit. A curling unit for curling metal shells is also provided. A press in combination with a curling unit for curling metal shells is also provided.
