Segmented Wedge Drive Guide for Long Tool Feed Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wedge drives face challenges with space constraints and wear issues due to the need for continuous sliding surfaces, which lead to vibrations and reduced precision when bridging longer distances, especially in complex production processes.
Innovation Solution
The wedge drive is enhanced by incorporating multiple sliding surfaces arranged one behind the other, allowing for an extended guide with the same overall height, enabling better distribution of forces and reduced wear, while allowing for adjustable angles and offsets to accommodate varying distances between the metalworking tool and the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the metalworking tool is extended with an intermediate piece to bridge a longer distance, then the distance to the workpiece is increased, but lateral forces cause vibrations and deformations leading to high wear and damage
Solution Approach 1:
The guide is divided into multiple guide sections arranged one behind the other in the thrust direction, with each section containing sliding surfaces. This segmentation allows the slide element to be supported at multiple points along its length, preventing vibrations and deformations while maintaining precision over extended distances.
2Area of stationary object
If the wedge drive is made taller to extend the feed path, then the sliding surface area is increased, but the cycle tool cannot accommodate larger distances due to design-limited stroke
Solution Approach 1:
Instead of extending the wedge drive vertically (one dimension), the guide sections are arranged sequentially in the thrust direction (another dimension), allowing extended feed paths within the existing vertical space constraints of the cycle tool.
3Productivity
If multiple wedge drives are combined in a single cycle tool, then production complexity increases, but space problems arise necessitating placement far from the contact point
Solution Approach 1:
The guide is segmented into multiple sections that can be independently configured, allowing multiple wedge drives to be compactly arranged within the cycle tool while maintaining adequate support for each metalworking tool.

AI summary
The present invention relates to a wedge drive (10) for reversibly advancing a metalworking tool (100), comprising a slide element receptacle (12) and a guide (14) for advancing in the thrust direction (X) of a slide element (16) supporting the tool (100) relative to the slide element receptacle (12) along a predetermined path, wherein the guide (14) for supporting the slide element (16) has a sliding surface (18) oriented in the thrust direction (X). To extend the feed path when the stroke of the metalworking tool (100) is limited by design, it is proposed that the guide (14) comprise at least two sliding surfaces (18) arranged one behind the other in the thrust direction (X). The present invention also relates to a cycle tool for machining a workpiece with a wedge drive (10).
