Wire Bending Feed Unit Layout for Compact Series Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an apparatus that can efficiently bend wire-like material, particularly sections of wire, to form tools like spanners with specific shapes such as L-shaped, S-shaped, or Z-shaped, while being compact, easily installable, and compatible with existing machinery for large-scale mass production.
Innovation Solution
The apparatus includes a gripping and feeding unit with comb-like jaws that synchronize to grip and transport wire sections to a bending unit, allowing for precise bending and forming of spanners, with a configuration that enables easy integration into existing machinery for high-speed production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional forging machines are used to bend wire sections, then the equipment can perform basic shaping, but the machine dimensions become large and require significant installation space
Solution Approach 1:
The patent applies nesting by placing the gripping and feeding unit inside the working unit structure. The gripping and feeding unit is positioned within the internal space of the working unit, allowing compact integration of multiple functions in a small volume while maintaining series-working capability for high productivity
Solution Approach 2:
The patent merges the gripping and feeding unit with the working unit into a single integrated apparatus. This combination eliminates the need for separate large-scale equipment, achieving both compact dimensions and high productivity through unified design
2Adaptability or versatility
If complex bending operations are performed to create L-shaped, S-shaped, or Z-shaped spanners, then product versatility increases, but the apparatus complexity increases
Solution Approach 1:
The patent applies dynamics by using a movable pressing element that can be repositioned along the wire section. This dynamic positioning capability allows the same apparatus structure to create various spanner shapes (L-shaped, S-shaped, Z-shaped) by changing the pressing element's position and movement pattern, achieving versatility without increasing structural complexity
Solution Approach 2:
The pressing element is designed as a universal component that can perform multiple bending operations. By adjusting the pressing element's position and movement, a single apparatus can produce different spanner configurations, making the device multi-functional without requiring complex specialized structures for each shape
3Manufacturing precision
If precise gripping and feeding of wire sections is implemented, then manufacturing precision improves, but the device complexity increases
Solution Approach 1:
The gripping and feeding unit is designed to automatically grasp and position wire sections without requiring complex external control systems. The unit self-regulates the feeding process, achieving precise positioning through its inherent mechanical design rather than through complex control mechanisms, thus maintaining manufacturing precision while minimizing device complexity
