Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balancing technologies for turning machines are inadequate in addressing continuously changing imbalances during the machining of material bars, leading to vibrations and oscillations, especially at high rotary speeds, and are not suitable for dynamically adjusting to changing imbalance conditions.
Innovation Solution
A balancing device for a bar loading magazine that includes a mass body which can be positioned and connected to the guiding unit or material bar, allowing it to rotate at the same angular speed, with a positioning unit that detects imbalances and repositions the mass body as needed to counteract centrifugal forces and maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high rotary speeds are used for machining material bars, then productivity is improved, but vibrations and oscillations increase due to imbalances
Solution Approach 1:
The patent applies counterweight principles by positioning mass bodies (counterweights) at specific locations on the guiding unit to balance the centrifugal forces generated by imbalanced material bars during rotation. The mass bodies are strategically placed to create opposing forces that neutralize the harmful vibrations and oscillations caused by imbalance, allowing high rotary speeds to be maintained without excessive vibrations.
Solution Approach 2:
The patent implements dynamic balancing by making the mass bodies positionable and adjustable on the guiding unit. This dynamic capability allows the balancing system to adapt to changing imbalance conditions as material bars are processed, enabling the system to maintain optimal balance at high rotary speeds throughout the machining process rather than relying on static balancing alone.
2Object-affected harmful factors
If mass bodies are added to counteract imbalance, then vibrations are reduced, but device complexity increases
Solution Approach 1:
The patent achieves versatility by designing the mass bodies to serve multiple functions: they act as counterweights to balance vibrations, can be positioned at different locations to address various imbalance scenarios, and integrate with the existing guiding unit structure. This multi-functionality reduces the need for separate balancing mechanisms, thereby limiting the increase in device complexity while still effectively reducing vibrations.
3Adaptability or versatility
If the guiding unit is designed to accommodate various material bar profiles, then adaptability is improved, but manufacturing precision requirements increase to maintain guidance accuracy
Solution Approach 1:
The patent applies local quality principles by designing the guiding unit with specific geometric features tailored to different material bar profiles. The guiding surfaces, support elements, and mass body positioning locations are locally optimized to accommodate various cross-sectional shapes (circular, square, hexagonal, etc.) while maintaining precise guidance. This localized adaptation allows high versatility without requiring excessive overall manufacturing precision across the entire device.

AI summary
A balancing device for a bar loading magazine for guiding material bars on a turning machine, includes at least one mass body that can be repeatedly positioned in relation to a guiding unit that allows a rotation of an introduced material bar about a rotary axis. The mass body is, after each completed positioning, in a connection with the guiding unit and/or the material bar, so that the mass body rotates, during the rotation of an introduced material bar, together with the material bar at the same angular speed about the rotary axis. At least one positioning unit is designed to bring the mass body into a starting position in relation to the guiding unit, to detect during rotation any required repositioning because of an imbalance, and to reposition in each case the mass body in response to the detection of any required repositioning in relation to the guiding unit.
