Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bending presses face challenges in maintaining forming accuracy and avoiding transverse forces on the drive device due to deformations of the machine frame under force application, which affects the precision and stability of the forming process.
Innovation Solution
The implementation of a resilient mounting ring that supports the drive means relative to the press frame, allowing for cardanic mounting and spring-elastic compensation of deformations, along with weakened zones in the pressure beam to distribute forces evenly and regulate deformation, ensuring stress-free force introduction and alignment of the drive means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive means is rigidly mounted on the press frame, then the mounting structure is simple and stable, but transverse forces occur on the drive device due to machine frame deformations under load
Solution Approach 1:
The mounting ring is designed with elastic properties, changing its mechanical parameter from rigid to flexible. This allows the mounting ring to deform elastically under load, accommodating machine frame deformations and preventing transverse forces from being transmitted to the drive means, thereby resolving the contradiction between maintaining forming accuracy and avoiding harmful transverse forces.
Solution Approach 2:
The mounting ring acts as an intermediary element between the press frame and the drive means. It mediates the interaction by absorbing and compensating for frame deformations through its elastic properties, protecting the drive device from transverse forces while maintaining reliable connection and forming accuracy.
2Manufacturing precision
If the mounting ring is rigidly connected to the press frame, then the drive means is firmly positioned, but deformations of the machine frame affect the alignment and forming accuracy
Solution Approach 1:
The mounting ring transitions from a rigid connection to an elastic connection, allowing it to adapt to frame deformations. This parameter change enables the mounting ring to maintain alignment stability by deforming with the frame rather than transmitting misalignment to the drive means, preserving forming accuracy.
Solution Approach 2:
The mounting ring introduces dynamic adaptability to the otherwise static mounting system. Its elastic properties allow it to dynamically adjust to frame deformations during operation, maintaining optimal alignment between the drive means and workpiece throughout the forming process.
3Manufacturing precision
If weakened zones are added to the pressure beam to compensate for deformations, then forming accuracy is improved, but the structural complexity of the pressure beam increases
Solution Approach 1:
The pressure beam is segmented by introducing weakened zones that create distinct functional regions. These zones divide the beam into segments that can independently deform or flex, allowing the beam to accommodate loads and maintain accuracy without requiring a completely redesigned complex structure.
Solution Approach 2:
The weakened zones create local variations in the pressure beam's structural properties. Rather than making the entire beam more complex, only specific local regions are modified to provide the necessary deformation characteristics, maintaining overall structural simplicity while improving forming accuracy.
