Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing tools lack flexibility and efficiency in producing different components, as they require one-off production of matrices tailored to specific workpieces, limiting the ability to quickly adapt to various designs and sizes.
Innovation Solution
A modular die module set comprising two different cores and two different reinforcement rings, allowing for the assembly of multiple matrices by combining these modules, enabling the creation of various matrices for producing different workpieces, with pre-stressing through interference fits to enhance force absorption during the forming process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a one-off production of a die is used for each specific workpiece, then the matrix is optimized for that specific workpiece, but the production time and flexibility are reduced
Solution Approach 1:
The matrix is divided into separate modular components: a core element and one or more reinforcement rings. These segments can be independently manufactured and then assembled in different configurations to create optimized matrices for different workpieces, eliminating the need for complete one-off production.
Solution Approach 2:
The core element and reinforcement rings are designed as universal components that can be used in multiple combinations. The same core can work with different reinforcement rings, and the same reinforcement rings can fit different cores, allowing a limited set of components to serve multiple functions for various workpiece types.
2Strength
If multiple reinforcement rings are used to absorb high forces, then the force absorption capability is improved, but the device complexity increases
Solution Approach 1:
The matrix configuration is made dynamic and adaptable. Instead of always using multiple reinforcement rings, the system allows selecting one or more reinforcement rings based on the specific force requirements of each workpiece. This dynamic configuration optimizes strength while minimizing unnecessary complexity.
3Reliability
If the outer diameter of the matrix is determined by the press receptacle, then the compatibility with the press is ensured, but the adaptability to different workpiece sizes is limited
Solution Approach 1:
The matrix is segmented into a core and reinforcement rings with standardized outer dimensions that fit the press receptacle. The adaptability to different workpiece sizes is achieved through varying the inner diameter configurations and wall thicknesses of these modular components, allowing the outer diameter to remain constant for press compatibility while the internal geometry adapts to different workpieces.

AI summary
A die module set (1) for a press tool for producing screws, threaded bolts and ball studs has two different cores (5, 14) and two different reinforcement rings (8, 11) which are designed to be matched to each other in such a way that a first die (2) with one core (5) and the reinforcement rings (8, 11) or alternatively a second die (2) with the other core (14) and only one of the reinforcement rings (11) can be assembled from them.
