Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transcript apparatuses face issues with minute positional displacement due to excessive pressing force and temperature variations, causing misalignment between the die and the forming product during the die-pressing process.
Innovation Solution
The apparatus features a body frame with guide frames and linear guides that allow the movable body to move symmetrically along die bars, supported by a servomotor and balance cylinders, which minimize lateral displacement by maintaining precise alignment and absorbing displacement caused by temperature changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If magnetic attraction force is used to press the die against the forming product, then the die and forming product are held in contact, but excessive pressing force causes frame deformation and minute positional displacement
Solution Approach 1:
A guide means (linear guides) is introduced as an intermediary component between the movable body and guide frames. This mediator constrains the movable body to move only along the die bars while preventing lateral displacement, thereby allowing magnetic attraction force to hold the die and forming product in contact without causing positional displacement due to frame deformation
Solution Approach 2:
The pressing force parameter is optimized by using magnetic attraction force instead of excessive mechanical force. The guide means also enables controlled movement along the die bars, changing the motion parameter from unrestricted to constrained linear movement, which prevents frame deformation while maintaining contact
2Stability of the object's composition
If the frame is made rigid to maintain alignment, then structural stability is improved, but temperature variations cause deformation and positional displacement
Solution Approach 1:
The frame structure is segmented into fixed components (body frame, guide frames) and movable components (movable body). The guide means provides a constraint system that allows the movable body to compensate for thermal expansion and contraction by moving along the die bars, while the fixed guide frames maintain their positions, thus preserving overall alignment despite temperature variations
Solution Approach 2:
The system transitions from a completely rigid static structure to a dynamic system where the movable body can move along the die bars within the guide means. This dynamic capability allows the system to adapt to temperature-induced dimensional changes while maintaining precise alignment through the constrained movement path
3Manufacturing precision
If the die and forming product are held in strict parallel alignment, then transcription precision is improved, but positional displacement occurs during die-pressing and die-removing processes
Solution Approach 1:
The guide means acts as an intermediary constraint system that maintains strict parallel alignment between the die and forming product during transcription. During die-pressing and die-removing processes, the movable body moves along the die bars within the guide means, which prevents lateral displacement and ensures the alignment is restored after the process
Solution Approach 2:
The guide means provides beforehand cushioning by constraining the movable body to move only along the die bars. This pre-established constraint prevents positional displacement from occurring during die-pressing and die-removing processes, cushioning against potential misalignment before it can affect transcription precision
