Interchangeable Lathe Tooling for Decorating Nozzle Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing decorating nozzles are costly and inflexible, requiring separate press tools for each nozzle diameter and limiting the range of sizes that can be produced efficiently.
Innovation Solution
A tool set for a metalworking lathe with concentric grooves and interchangeable forming tools allows for the progressive deformation of sheet metal to create nozzle components, enabling the production of a variety of nozzle sizes with reduced tooling costs and increased flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate press tools are manufactured for each nozzle diameter, then manufacturing precision is maintained, but device complexity and manufacturing cost increase
Solution Approach 1:
A single press tool is designed to produce multiple nozzle diameters by incorporating interchangeable forming inserts. The tool body remains constant while different inserts can be swapped to create various nozzle sizes, making one tool perform multiple functions that previously required separate tools for each diameter.
Solution Approach 2:
The press tool is divided into modular components: a reusable tool body and interchangeable forming inserts. This segmentation allows the forming inserts to be replaced or adjusted for different nozzle diameters while maintaining the precision and structural integrity of the main tool body.
2Manufacturing precision
If separate press tools are manufactured for each nozzle diameter, then manufacturing precision is maintained, but manufacturing cost increases
Solution Approach 1:
A single press tool is designed to produce multiple nozzle diameters by incorporating interchangeable forming inserts. The tool body remains constant while different inserts can be swapped to create various nozzle sizes, making one tool perform multiple functions that previously required separate tools for each diameter.
Solution Approach 2:
Instead of discarding the entire press tool when changing nozzle diameters, only the forming inserts are replaced. The expensive tool body is recovered and reused, significantly reducing the cost of producing different nozzle sizes compared to manufacturing completely separate tools for each diameter.
3Manufacturing precision
If a fixed press tool is used for each nozzle size, then manufacturing precision is ensured, but adaptability decreases
Solution Approach 1:
The press tool system transitions from a static, fixed-diameter configuration to a dynamic, adjustable system. Interchangeable forming inserts allow the tool to adapt its forming surface to match different nozzle diameter requirements, enabling one tool to dynamically serve multiple nozzle size specifications.
Solution Approach 2:
A single press tool is designed to produce multiple nozzle diameters by incorporating interchangeable forming inserts. The tool body remains constant while different inserts can be swapped to create various nozzle sizes, making one tool perform multiple functions that previously required separate tools for each diameter.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces nozzle tooling costs, allows for a wider range of nozzle sizes, minimizes dead space when nozzles are placed together, and optimizes factory space usage.
Implementation Method 1
pressing a roller on to the disc adjacent to the center of the disc and tangentially to the rotating surface thereof, and progressively moving the roller outwardly while continuing to press the roller on to the disc to deform the disc to adopt the shape of the convex forming tool

AI summary
Disclosed is a tool set for use in forming the components of a decorating nozzle from sheet metal. A tool-mounting plate mountable on the headstock of a metalworking lathe is configured with concentric grooves into which circular ribs on the tools can locate. Transverse formations prevent relative rotation between the tool and the tool-mounting plate. A method of forming nozzles comprises rolling a metal blank onto the surface of a forming tool as the tool is rotated in the lathe. Successive tools are used to achieve the desired shape.
