Movable Holding Elements for Hot Forming Machine Preloading Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hot forming machines require manual and time-consuming retooling to accommodate different glass tube diameters, leading to inefficiencies in positioning and processing.
Innovation Solution
A positioning device with movable holding elements in the form of shears, allowing for dynamic adjustment of guide geometries by overlapping in adjacent planes, enabling secure gripping of various glass tube diameters without manual retooling, and featuring a piston-connecting rod mechanism for symmetrical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dimension-dependent inserts are used to position glass tubes of different diameters, then positioning precision is maintained, but retooling time increases and device complexity increases
Solution Approach 1:
The holding elements are made movable relative to each other, allowing dynamic adjustment of the recess geometry to accommodate different glass tube diameters. This replaces static dimension-dependent inserts with a dynamic positioning system that can be rapidly reconfigured.
Solution Approach 2:
The holding elements move in different but mutually adjacent planes rather than in a single plane, creating overlapping geometries that enable the formation of different guide openings for various tube diameters without requiring multiple fixed inserts.
2Manufacturing precision
If multiple dimension-dependent inserts are used for different glass tube diameters, then positioning accuracy is maintained, but device complexity increases
Solution Approach 1:
The holding elements serve multiple functions: they hold the glass tube, position it accurately, and can be adjusted to accommodate different diameters. This universal design replaces multiple specialized inserts with a single multi-functional positioning system.
Solution Approach 2:
The movable holding elements allow the positioning device to dynamically adapt to different glass tube diameters, replacing the need for multiple static inserts with a single adjustable mechanism that maintains positioning accuracy across various dimensions.
3Device complexity
If holding elements move in one plane like tongs, then结构简单性 is maintained, but adaptability to different tube diameters decreases
Solution Approach 1:
The holding elements move in different but mutually adjacent planes, adding a dimensional aspect to the movement. This enables the creation of overlapping geometries that can accommodate various tube diameters while maintaining relatively simple structures.
Solution Approach 2:
The holding elements are designed to move relative to each other, transforming a static simple structure into a dynamic one that can adapt to different tube diameters through controlled movement in adjacent planes.

AI summary
A positioning device for a preloading ring of a hot forming machine is provided. The device has a first holding element and a second holding element. The first holding element has a first recess and a second recess. The second recess is at a distance radially with respect the first recess. The second holding element is arranged in a region of and faces the first and second recess. The first and second holding elements are configured and arranged movably about respective axes with respect to each other so that movement towards each other encloses a glass tube in each of the first and second recesses and between the holding elements.
