Press Jaw Locking Assembly for Wear-Resistant Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing tools with fiber composite materials suffer from impaired connections between pressing levers and jaws during the pressing process, leading to inconsistent compression quality and wear issues.
Innovation Solution
A pressing lever arrangement featuring a pressing lever with a receptacle and a pressing jaw connected via a securing element, preventing relative displacement, utilizing tempered steel for the lever and case-hardened steel for the jaw, with securing elements like pins, elevations, and material connections to ensure stable and wear-resistant performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the press jaw is firmly connected to the press lever during curing, then the connection is strong, but the connection can be impaired during the pressing process
Solution Approach 1:
The connection system is segmented into multiple independent locking elements (at least one locking element) that distribute the locking function across several points, preventing single-point failure and maintaining reliable connection throughout the pressing process
Solution Approach 2:
The locking elements are pre-installed and configured to engage the press jaw with the press lever before the pressing operation begins, ensuring the connection is established and secured in advance to prevent impairment during use
2Weight of moving object
If the press jaw and press lever are made of composite material, then weight is reduced, but wear resistance deteriorates
Solution Approach 1:
The solution uses composite construction by combining different materials - the press lever and press jaw are made from material combinations that optimize both weight and wear resistance properties, rather than using a single material for both components
3Stability of the object's composition
If the press jaw is firmly connected to the press lever, then positioning is stable, but displacement prevention is insufficient
Solution Approach 1:
The locking elements extend in multiple directions and dimensions to constrain the press jaw against the press lever, preventing displacement not only along the pressing axis but also in lateral directions, adding dimensional constraints to the connection
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
Maintains consistent compression quality over multiple uses and enhances wear resistance, allowing for interchangeable jaws and easy maintenance, while ensuring precise alignment and secure fixation of the jaw within the lever receptacle.
Implementation Method 1
The press lever is made of heat-treated steel, and the press jaw is made of case-hardening steel
Implementation Method 2
the press jaw is made of case-hardening steel

AI summary
A pressing lever arrangement (1) comprises a pressing lever (2) and a pressing jaw (3), the pressing lever (2) having a pressing jaw receptacle (4) with a receiving surface (5) and the pressing jaw (3) having a central axis (M) has a partially extending pressing surface (6) with a pressing contour (7) and a receiving surface (8), the pressing jaw (3) being positionable with its receiving surface (8) in the pressing jaw receptacle (4) of the pressing lever (2). The pressing lever arrangement (1) further comprises at least one securing element (9; 10, 11) which is arranged or designed in such a way that relative displacement between the pressing jaw (3) and the pressing jaw receptacle (4) can be prevented.
