Radial Press Jaw Mounting With Recess-Guided Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radial presses face limitations in flexibility and precision when mounting press jaws of varying diameters, often requiring manual alignment and risking damage to fixation projections, and struggle with axial offset and weakening of base jaws during axial mounting.
Innovation Solution
The base jaws are equipped with channel-like recesses extending from the seat to the side face, allowing fixation projections to rotate into position during mounting, reducing the required distance between bracing faces and enabling longer projections, precise alignment, and minimizing axial offset, while cutouts provide additional support and symmetry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If press jaws are mounted by axial movement onto base jaws, then mounting speed is improved, but the base jaws are weakened and axial offset occurs
Solution Approach 1:
The patent transitions from axial mounting direction to radial mounting direction. The press jaws are mounted by radial movement onto the base jaws, changing the dimension of mounting action from axial to radial. This resolves the contradiction because radial mounting does not require axial slots in the base jaws, maintaining base jaw strength while enabling automated quick-changing mechanisms for high productivity.
2Manufacturing precision
If fixation projections are made longer to improve alignment precision, then mounting precision is improved, but the risk of damage to projections increases
Solution Approach 1:
The patent introduces guide surfaces as an intermediary element between the fixation projections and seats. These guide surfaces, extending from the pressing surface toward the opening, provide preliminary alignment and guidance for the fixation projections during radial mounting. This allows for precise alignment without requiring excessively long projections, thereby maintaining projection durability while achieving mounting precision.
3Manufacturing precision
If manual alignment is used to ensure precise mounting, then mounting precision is improved, but operation complexity increases
Solution Approach 1:
The patent implements self-aligning features where the guide surfaces on the base jaws automatically guide the fixation projections of the press jaws into correct alignment during radial mounting. The quick-changing mechanism utilizes the radial movement of base jaws to automatically position press jaws without requiring manual alignment operations. This achieves mounting precision while simplifying operation through automated self-alignment.
4Adaptability or versatility
If press jaws are mounted individually to allow flexibility, then adaptability is improved, but mounting time increases
Solution Approach 1:
The patent combines multiple press jaws into a single press-jaw set that can be mounted or removed as one unit using the quick-changing mechanism. The base jaws move radially together, enabling simultaneous mounting/demounting of multiple press jaws. This merging approach maintains adaptability by allowing different sets to be exchanged while dramatically reducing mounting time compared to individual jaw changes.

AI summary
A radial press has a plurality of press bodies arranged around a press axis which can be moved radially in relation to the press axis, and a drive unit for shifting the press bodies in the direction of or away from the press axis. The press bodies each have a main jaw and a pressing jaw, which is fixed interchangeably on the main jaw. The main jaws each comprise a radially inwardly arranged pressing-jaw-supporting surface and, adjacent to the latter in the circumferential direction, two side surfaces. The pressing jaws butt against the pressing-jaw-supporting surface of the associated main jaw and have a fixing protrusion, which projects from the abutment surface, enters into a mount provided on the main jaw and interacts with a locking device. Each main jaw has a recess on its supporting surface which extends from the mount and opens out on one of the side surfaces.
