Form-Rolling Device for Adjustable Groove Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing form-rolling devices are limited to processing tubes of specific sizes and cannot form grooves at arbitrary positions from the tube end, making them unsuitable for SUS tubes with various diameters.
Innovation Solution
A form-rolling device comprising a shaft with a convex roller and a concave roller, along with a flange-shaped tube-end positioning member and a supporting member, allows for adjustable positioning of grooves on tubular members of various sizes, enabling groove formation at arbitrary positions from the tube end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a form-rolling device is designed for a specific tube size, then groove formation precision is improved, but adaptability to various tube diameters deteriorates
Solution Approach 1:
The concave roller is made movable in the axial direction relative to the convex roller, allowing the distance between them to be adjusted. This dynamic adjustment enables the device to accommodate tubes of various diameters while maintaining precise groove formation through controlled roller positioning.
Solution Approach 2:
The device is designed with adjustable components that allow a single form-rolling device to process multiple tube diameters. The movable concave roller and adjustable tube-end positioning member enable one device to perform the grooving function universally across different tube sizes rather than requiring dedicated devices for each size.
2Stability of the object's composition
If the groove position is fixed at a certain distance from the tube end, then processing consistency is improved, but flexibility in groove positioning deteriorates
Solution Approach 1:
The tube-end positioning member is made movable in the axial direction, allowing the distance between the tube end and the convex roller to be adjusted. This enables flexible groove positioning at arbitrary distances from the tube end while maintaining consistent processing through controlled positioning.
Solution Approach 2:
The device allows operators to independently adjust the positioning member and concave roller to achieve the desired groove position for each specific application, providing self-adjustable flexibility rather than requiring fixed pre-configured positions.
3Device complexity
If the concave roller is fixed in position, then device simplicity is improved, but positioning flexibility deteriorates
Solution Approach 1:
The concave roller is designed to move in the axial direction through a simple movable support structure. This minimal movement capability provides the necessary positioning flexibility for various tube diameters without introducing complex mechanisms, maintaining device simplicity while enabling adaptability.
