Wire Straightening Device with Adjustable Roller Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feed and straightening devices for wires or double wires struggle with efficient wire thickness changes, leading to significant production interruptions when the wire thickness varies, as they require substantial time for changeover and are not designed for selecting the correct wire from multiple options.
Innovation Solution
A device with vertically and horizontally adjustable roller carriers, a vertical traversing system, and a horizontal movement mechanism allows for the selection and alignment of the correct wire thickness, enabling rapid wire changes by moving pairs of roller carriers to match the production line height and position, utilizing hydraulic cylinders and U-shaped swivel arms for precise alignment and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wires of different thicknesses are stored and manually selected, then wire thickness variety is improved, but wire change time increases significantly
Solution Approach 1:
The roller carriers are made movable both vertically and horizontally, allowing dynamic repositioning of different wire thicknesses to the production line position. This dynamic capability enables rapid wire changes without manual intervention, resolving the contradiction between wire variety and change time
Solution Approach 2:
The roller carriers serve multiple functions: storing wires of different thicknesses, transporting them vertically and horizontally, and positioning them at the production line. This multi-functionality allows a single system to handle wire variety while maintaining rapid change capability
2Adaptability or versatility
If feed rollers are made height-adjustable, then wire thickness adaptability is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical adjustment systems with a simpler hydraulic actuation system. The hydraulic cylinder-piston unit provides height adjustment through fluid pressure, eliminating the need for complex mechanical linkages and making the adjustment process more reliable and easier to control
Solution Approach 2:
A hydraulic cylinder-piston unit is used to actuate the feed roller height adjustment. This hydraulic mechanism provides smooth, controlled movement and can hold position without continuous power input, reducing device complexity compared to mechanical alternatives while improving adaptability

Function Achieved in This Case
This solution significantly accelerates wire changes by allowing the selection and feeding of the correct wire thickness from multiple options, reducing production interruptions and maintaining continuous operation.
Implementation Method 1
hydraulic cylinder-piston units are provided for the common vertical movement of all groups of roller carriers in the vertical guides of the frame
Implementation Method 2
each roller carrier is connected to one leg of a U-shaped swivel arm, which leg can be moved vertically in the vertical guide and pivoted about an axis
