Wire-drawing Device Modular Roller Die Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire-drawing devices require high skill for assembly and adjustment, particularly in positioning and cooling of roller dies, leading to variability in wire diameter and increased load on bearings, and are not easily handled by non-skilled workers.
Innovation Solution
A wire-drawing device with a frame and separate supporting bodies for roller dies, utilizing a first positioning means for axial adjustment and a second positioning means for radial adjustment, along with integrated cooling mechanisms, allowing easy assembly and adjustment without direct attachment to the frame, and facilitating cooling medium passage without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If roller dies are directly attached to the frame with bearing-box-fixing beams and bolts, then the structure is rigid and stable, but the assembly and adjustment require high skill and are time-consuming
Solution Approach 1:
The device is divided into modular components: roller dies are mounted on supporting shafts that can be independently positioned and adjusted within the frame. The supporting shafts are segmented into adjustable segments that can be moved to different positions along the frame using positioning mechanisms, allowing flexible assembly without requiring high skill or time-consuming adjustments.
2Temperature
If cooling-medium passages are integrated into the frame structure, then cooling coverage is extended, but heat transmission from roller dies is insufficient
Solution Approach 1:
Supporting shafts serve as intermediary components that directly contact the roller dies and conduct heat away from them. The cooling-medium passages are integrated into the supporting shafts rather than the frame, creating a direct thermal pathway from the roller dies through the supporting shafts to the cooling medium, thereby improving heat transmission efficiency while maintaining effective cooling.
3Manufacturing precision
If multiple adjustment mechanisms are provided for roller die positioning, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The supporting shafts are designed with multi-functionality: they provide structural support for the roller dies, serve as heat conduction pathways for cooling, and incorporate positioning mechanisms that enable both axial and radial adjustments. This universal design allows a single component to perform multiple functions, reducing the need for separate adjustment mechanisms while maintaining positioning precision for consistent wire diameter.
