Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing brush manufacturing machines face difficulties in complex processing of brush bodies due to limitations in holding elements that support brush bodies during rotation, making it challenging to handle centrifugal forces and facilitate processing.
Innovation Solution
The brush manufacturing machine incorporates an adjusting mechanism with a swivel drive and actuating elements, allowing the holding elements to move from a holding position to a processing position, enabling unrestricted processing of brush bodies while supporting them against centrifugal forces, and utilizing a swivel drive to align clamping positions for efficient processing, especially with stuffing tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If holding elements are used to support brush bodies during rotation of the tensioning drum, then the machine can operate at high speeds, but complex machining of the brush bodies becomes more difficult
Solution Approach 1:
The holding element is designed to be movable between a holding position (close to the clamping station) and a processing position (remote from the clamping station). This dynamic repositioning allows the system to adapt its structure based on the operational phase: during rotation, the holding element supports the brush body at high speed, and during processing, it moves away to enable unrestricted machining operations
Solution Approach 2:
The holding element periodically transitions between the holding position and the processing position in synchronization with the rotation of the tensioning drum. This periodic action ensures that the brush body is supported during rotation phases and accessible during processing phases, resolving the contradiction between high-speed operation and complex machining requirements
2Force
If the holding element is positioned close to the clamping station to support the brush body, then centrifugal forces are counteracted, but the brush body cannot be processed without restriction
Solution Approach 1:
The holding element's position is dynamically adjusted based on the operational requirements. When the clamping station is in the processing position, the holding element moves to the processing position (remote from the clamping station), allowing unrestricted access for processing tools. When the tensioning drum rotates, the holding element moves to the holding position to provide necessary support against centrifugal forces
3Ease of manufacture
If the holding element is moved into the processing position to allow unrestricted processing, then machining freedom is achieved, but the brush body must be supported against centrifugal forces during rotation
Solution Approach 1:
The system implements periodic action by synchronizing the movement of the holding element with the rotation of the tensioning drum. The holding element is positioned close to the clamping station during rotation to counteract centrifugal forces, and moves to the processing position during processing phases to allow unrestricted machining
Solution Approach 2:
The holding element is designed as a dynamic component that can change its position relative to the clamping station. This dynamic capability allows it to provide force support when needed during rotation and move away to allow processing freedom when the processing position is reached
