Pivoting Press Tool Jaws for Lateral Press Tabs in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing tools struggle to effectively press fittings with laterally projecting press tabs in tight assembly conditions, as they require significant space for gripping and cannot achieve bilateral contact with the press tab.
Innovation Solution
A pressing tool with two pivoting adjusting levers and associated pressing levers, equipped with joints that allow transverse pivoting, enabling the pressing jaws to contact the press tab on both sides, even in confined spaces, using a servomotor for actuation and locking devices for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional pressing tool is used to press fittings with laterally projecting press tabs, then the pressing action can be performed, but the tool requires significant space for gripping and cannot achieve bilateral contact with the press tab in tight assembly conditions
Solution Approach 1:
The pressing tool employs adjustable pressing levers that can be dynamically repositioned along the pressing jaw, allowing the tool to adapt its configuration to fit within tight spatial constraints while maintaining the ability to apply pressing force to the press tab
Solution Approach 2:
The pressing tool is divided into separate functional components including adjustable pressing levers, pressing jaws, and positioning mechanisms, allowing each segment to be independently positioned to achieve bilateral contact with the press tab in confined spaces
2Reliability
If the pressing tool is designed to contact the press tab on both sides, then bilateral contact is achieved, but the device complexity increases due to additional adjusting mechanisms
Solution Approach 1:
The adjusting mechanisms serve multiple functions: they position the pressing levers to achieve bilateral contact with the press tab, they allow adaptation to different press tab configurations, and they enable the tool to operate in various spatial configurations, thereby reducing the need for separate specialized components
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
Enables the pressing of fittings with laterally projecting press tabs in tight spaces by allowing the pressing levers to pivot transversely, ensuring bilateral contact and efficient pressing, even where space is limited.
Implementation Method 1
Each joint (29, 30) has a joint head (31) which is guided in a joint socket (33)
Implementation Method 2
Each locking device (37, 38) has a locking element (39) which is preloaded against a locking contour (45) by a spring
Implementation Method 3
The pressing tool then engages the sleeve around its entire circumference to achieve plastic deformation

AI summary
The invention relates to a pressing tool (1) comprising two actuating levers (4, 5) which are pivotable relative to each other in an actuating plane (12) and each is coupled to an associated pressing lever (21, 22), each of which is equipped with a pressing jaw (26, 27). When pivoting, each actuating lever (4, 5) takes its respective associated pressing lever (21, 22) with it in its pivoting movement, whereby the pressing jaws (26, 27) of the pressing levers (21, 42) move either towards each other or away from each other in a pressing plane (28), depending on the pivoting movements of the actuating levers (4, 5) relative to each other.Furthermore, the coupling of the respective actuating lever (4, 5) with the respective associated pressing lever (21, 22) is carried out via a joint, which transmits the pivoting movement of the respective actuating lever (4, 5) to the respective associated pressing lever (21, 22) and thereby enables different laterally pivoted positions of the respective associated pressing lever (41, 42) relative to the respective actuating lever (4, 5).
