Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radial presses are limited in their ability to deform large workpieces with high pressing force and lack flexibility to handle workpieces of varying sizes, especially those smaller than the maximum size, due to limitations in the design and the use of restoring springs.
Innovation Solution
The implementation of a radial press with compulsory guidance of pressing elements via guide slots and guide rollers on the ring structures, eliminating the need for restoring springs and allowing for precise control and adaptation to different workpiece sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If restoring springs are used to reset pressing elements during opening of the radial press, then the pressing elements can automatically return to the initial position, but the press lacks flexibility to handle workpieces of varying sizes and smaller workpieces cannot be reliably formed
Solution Approach 1:
The patent removes the restoring springs from the system entirely. Instead of using springs to automatically reset the pressing elements, the invention uses a different mechanism (hydraulic or pneumatic actuators) to control the movement of pressing elements, thereby eliminating the limitation that springs impose on handling workpieces of varying sizes while still achieving automatic resetting functionality
Solution Approach 2:
The invention changes the control parameter from passive spring force to active hydraulic/pneumatic pressure control. This allows precise adjustment of the pressing element position and force, enabling the press to adapt to different workpiece sizes and shapes while maintaining automatic resetting capability through controlled parameter adjustment
2Force
If the radial press is designed for high pressing force to deform large workpieces, then large workpieces can be effectively deformed, but the press cannot reliably handle smaller workpieces due to tilting and lift-off issues
Solution Approach 1:
The patent employs dynamically controllable hydraulic or pneumatic actuators that can adjust the pressing force in real-time. This dynamic control allows the system to apply appropriate force levels for different workpiece sizes, preventing tilting and lift-off of smaller workpieces while maintaining the capability to deform large workpieces with high force
Solution Approach 2:
The invention incorporates feedback control mechanisms that monitor the position and force applied to the workpiece. This feedback allows the system to automatically adjust the pressing force distribution, ensuring reliable handling of workpieces of varying sizes by preventing tilting and lift-off while maintaining effectiveness for large workpieces
3Manufacturing precision
If guide slots and guide rollers are implemented for compulsory guidance of pressing elements, then tilting and lift-off are prevented improving precision, but the device complexity increases
Solution Approach 1:
The patent introduces guide slots and guide rollers as intermediary elements between the pressing elements and the workpiece. These intermediaries provide compulsory guidance that prevents tilting and lift-off, improving manufacturing precision. While this adds some complexity, the guide mechanism is integrated into the existing press structure, minimizing the increase in overall device complexity

AI summary
A radial press is provided having a first and a second ring structure extending about a press axis. Multiple press bodies are arranged about the press axis between the ring structures and are movably supported on support surfaces paired with the ring structures. The axial distance between the two ring structures can be changed using a drive system having a plurality of actuators oriented parallel to the press axis and distributed about the press axis. The support surfaces paired with one of the two ring structures are inclined relative to the press axis, and the press bodies are guided in a forced manner relative to the two ring structures in that the press bodies are equipped with guide grooves into which guide bodies engage.
