Innovation Solution
A compact cutting device with an adjustable mechanism that allows for easy conversion between different wire diameters using a single cutting sleeve with multiple openings and a drive system, such as a worm gear or toothed belt, enabling precise and efficient cutting of wires with varying diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple separate cutting devices are used for different wire diameters, then cutting precision for each wire diameter is improved, but device complexity and space requirements increase
Solution Approach 1:
The cutting device uses a single multi-functional cutting bushing with multiple openings of different diameters. The cutting bushing can be rotated to bring different openings into the machining position depending on the wire diameter being processed. This allows one cutting device to handle multiple wire diameters, reducing the need for multiple separate cutting devices while maintaining cutting precision for each diameter.
Solution Approach 2:
The cutting bushing is designed to be rotatable around its axis, allowing dynamic adjustment between different openings. The rotation mechanism enables the operator to select the appropriate opening size matching the wire diameter, transforming a static single-opening bushing into a dynamic multi-opening system that adapts to different cutting requirements.
2Manufacturing precision
If multiple separate cutting devices are used for different wire diameters, then cutting precision for each wire diameter is improved, but the space required and costs increase
Solution Approach 1:
The cutting bushing integrates multiple openings of different diameters into a single component, allowing one cutting device to serve multiple wire diameter requirements. This consolidation reduces the total space needed compared to having separate cutting devices for each wire diameter, while still providing precise cutting for each size.
Solution Approach 2:
Multiple cutting functions for different wire diameters are merged into a single cutting bushing component. By combining several openings in one bushing and allowing rotation between them, the design merges what would otherwise require multiple separate devices into one compact unit, reducing both space and cost.
3Ease of operation
If the cutting bushing diameter is significantly larger than the wire diameter, then the wire can be guided through the opening, but the wire moves excessively during cutting resulting in imprecise and unclean cuts
Solution Approach 1:
Instead of using a single large cutting bushing opening for all wire diameters, the invention provides multiple openings with different diameters, each locally optimized for specific wire sizes. The opening diameter is matched to the wire diameter being processed, providing appropriate guidance without excessive movement. This local optimization ensures both ease of operation and high cutting precision for each wire size.
4Manufacturing precision
If manual replacement of cutting dies is performed for different wire diameters, then the wire guide can be adjusted to the current wire diameter, but this requires a technician and is time-consuming
Solution Approach 1:
The cutting bushing is designed with rotational capability, allowing quick switching between different openings by simply rotating the bushing to the desired position. This dynamic adjustment mechanism eliminates the need for manual replacement of entire cutting dies, reducing changeover time from minutes to seconds while maintaining precise wire guidance for each diameter.
Solution Approach 2:
Multiple openings for different wire diameters are pre-configured in the cutting bushing at specific angular positions. This preliminary arrangement allows the operator to quickly select the appropriate opening by rotating to the predetermined position corresponding to the current wire diameter, eliminating the need for technician intervention and complex adjustment procedures.

AI summary
The invention relates to a cutting device (2) for cutting wire, comprising a movable blade (15.1, 15.2) for cutting the wire, a cutting sleeve (6.1) with a first opening for guiding the wire to be cut, wherein the first opening has a first internal dimension, and a second opening which has a second internal dimension different from the first internal dimension. The first or the second opening can be in a working position in which the wire can be sheared by the blade (15.1, 15.2). The cutting device (2) has an adjustment mechanism (5) for adjusting the cutting sleeve (6.1) in order to selectively bring either the first or the second opening of the cutting sleeve (6.1) into the working position.
