Reciprocating Cutter Assembly for Tire Bead Wire Cutting
Solution Overview
Problem
Existing wire cutting technologies for tire bead winders lack efficient mechanisms for precise and simultaneous cutting of multiple wires at varying lengths, often resulting in reduced accuracy and increased maintenance due to limited cutting edge utilization.
Innovation Solution
A reciprocating cutter assembly with a housing supporting a fixed first cutter and a movable second cutter, equipped with opposed cutting blades that translate towards each other, driven by an actuator, allowing for precise cutting of wires by aligning recesses and utilizing multiple cutting edges to extend the lifespan of the cutters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a single cutter with limited cutting edges is used, then the device complexity is reduced, but the duration of action of the cutter is limited and maintenance frequency increases
Solution Approach 1:
The cutting system is segmented into multiple independent cutters (first cutter and second cutter), each with its own cutting edges. This allows the cutters to be used alternately or simultaneously, extending the overall duration of action while maintaining manageable complexity through modular design.
Solution Approach 2:
The second cutter is made reciprocatingly movable relative to the first cutter, allowing dynamic switching between cutting edges. This dynamic configuration enables extended usage by alternating between cutters, effectively doubling the duration of action while using a standardized cutter design to control complexity.
2Duration of action of moving object
If multiple cutters are used to extend lifespan, then the duration of action is improved, but the device complexity increases
Solution Approach 1:
Both the first and second cutters are designed with identical structures, each having a body with a recess and cutting blades disposed on walls defining the recess. This universal design allows either cutter to perform the cutting function, effectively multiplying the duration of action while keeping the added complexity minimal through standardization.
3Adaptability or versatility
If a fixed cutter configuration is used, then the ease of operation is improved, but the adaptability to different wire lengths is reduced
Solution Approach 1:
The second cutter is configured to be reciprocatingly movable relative to the first cutter and the housing, allowing the cutting system to adapt to different wire lengths and positions. This dynamic configuration provides versatility for various wire lengths while maintaining ease of operation through automated reciprocating motion driven by an input device.

AI summary
A cutting apparatus for an elongate wire is provided, and includes a housing that supports a first cutter that has a body, a recess, and a cutting blade. The cutting blade is disposed upon a wall of the body that defines the recess, the first cutter is fixed with respect to the housing. The housing additionally supports a second cutter that has a body, a recess, and a cutting blade, wherein the cutting blade is disposed upon a wall of the body that defines the recess. The second cutter is normally positioned with respect to the first cutter such that the recess of the first cutter is aligned with the recess of the second cutter, and is movable to a second position where the recess of the second cutter translates with respect to the recess of the first cutter, such that the respective cutting blades translate toward each other.
