Wire Forming Tool Selection Table for Flexible Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire forming apparatuses lack flexibility in cutting tool placement and operation, leading to limited degree of freedom in machining, particularly when cutting wires with diameters of 5 mm or more, as the cutting tool must slide and apply force against a wire guide, risking deformation or damage.
Innovation Solution
A wire forming apparatus with a tool selection table that supports both forming and cutting tools, allowing the cutting tool to reciprocate relative to a receiving portion and share a common driving source with coiling tools, enabling more flexible cutting positions and processes, including cutting during formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cutting tool is slidably mounted on auxiliary tool apparatus separately fixed on a base, then the cutting tool can be positioned, but the degree of freedom in machining is limited and the wire guide may be deformed or damaged when cutting wires with diameter of 5 mm or more
Solution Approach 1:
The patent merges the cutting tool with the tool selection table that also supports forming tools. The cutting tool is now integrated into the same rotatable table structure that holds multiple forming tools, allowing unified positioning and selection. This eliminates the need for separate auxiliary tool apparatus and enables the cutting tool to be positioned at various locations on the table, greatly increasing machining freedom while avoiding forces applied to the wire guide.
Solution Approach 2:
The tool selection table is designed to universally support both forming tools and cutting tools. The table structure and positioning mechanism are made multi-functional to accommodate different tool types. This allows the same table to perform both wire forming operations and cutting operations, eliminating the need for separate dedicated cutting apparatus and enabling flexible switching between operations.
2Adaptability or versatility
If the cutting tool always cuts the wire at the same position, then the structure is simplified, but the degree of freedom in selecting cutting portion in the process of formation is limited
Solution Approach 1:
The cutting tool position on the tool selection table is made dynamically adjustable rather than fixed. The table can be rotated to bring different tool positions into the working location, and the cutting tool itself can be positioned at multiple locations on the table. This dynamic positioning capability allows cutting at various points along the wire formation process without requiring a completely fixed rigid structure.
Solution Approach 2:
The tool selection table is divided into multiple tool mounting positions arranged circumferentially. Each position can hold a different tool or the same cutting tool at different angular positions. This segmentation allows the cutting operation to be performed at different stages of wire formation by selecting appropriate table rotation angles, providing flexibility in choosing where to cut the wire.

AI summary
A wire forming apparatus which feeds out a wire (W) from a distal end portion of a wire guide (402), forcibly bends, curves, or winds the wire by using a forming tool (T1-T5) and forms the wire into a part with a desired shape by using a cutting tool (T0), wherein the forming tool includes a coiling tool of which a coiling spindle rotates about its central axis, a coiling tool unit (T1, T2) which rotatably supports the coiling tool and a cutting tool unit (T0) which supports a cutting blade (506) and a receiving portion (507) constituting the cutting tool so as to allow the cutting blade and the receiving portion to relatively reciprocate are attached to the tool selection table (210), and a common driving source is provided to apply driving force to the coiling tool unit and the cutting tool unit attached on the tool selection table.
