Solution Overview
Problem
Press bending machines face deformation issues during plate conformation, leading to inefficiencies in shaping and bending processes due to unregulated distances between aprons and uprights, which affects the machine's ability to handle plates of varying dimensions and shapes.
Innovation Solution
A deformation compensation system is introduced, comprising uprights with coupled beams and a compensation actuator driven by sensors, converters, and amplifiers, allowing for adjustable distances and enhanced rigidity through mechanical or hydraulic actuation, enabling precise control over beam lengths and stress distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between aprons and uprights is fixed, then the machine structure is simple, but the machine cannot handle plates of varying dimensions and shapes
Solution Approach 1:
The patent implements a compensation actuator that dynamically adjusts the position of the upper apron relative to the uprights, transforming the fixed structure into an adjustable one. This allows the machine to adapt to different plate dimensions while maintaining a relatively simple overall structure through controlled dynamic modification.
Solution Approach 2:
The system changes the positional parameter of the upper apron by using the compensation actuator to modify the distance between the apron and uprights. This parameter adjustment enables the machine to handle various plate sizes without requiring complete structural redesign.
2Productivity
If deformation compensation is not implemented, then the machine structure is simple, but the shaping and bending processes are inefficient
Solution Approach 1:
The compensation system uses sensors to detect deformation and feeds this information back to the control system, which then activates the compensation actuator to counteract the deformation. This feedback mechanism improves shaping efficiency by maintaining structural integrity during operation.
Solution Approach 2:
The compensation actuator applies a counteracting force to the deformation before it significantly affects the bending process. By anticipating and counteracting deformation trends, the system maintains process efficiency without requiring complete structural redesign.
3Adaptability or versatility
If the beam length is fixed, then the assembly is simple, but the machine cannot regulate the scye zone dimensions for different plate widths
Solution Approach 1:
The beam is designed with adjustable length capability through the compensation actuator system, allowing dynamic modification of the scye zone dimensions. This enables the machine to accommodate different plate widths while maintaining assembly simplicity through a standardized adjustment mechanism.
