Solution Overview
Problem
Current methods for producing molded parts with multiple layers are complex and require separate steps for cladding and forming, limiting efficiency and flexibility in material selection and thickness ratios.
Innovation Solution
A method that integrates cladding and forming of sheet metal materials in a single work step using flow-forming, spinning, or deep-drawing processes, allowing for simultaneous plating and shaping without the need for hot rolling, enabling individualized production of molded parts with varying layer thicknesses and materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate steps for cladding and forming are used, then secure bonding between layers is achieved, but production complexity and time increase
Solution Approach 1:
The patent combines cladding and forming operations into a single integrated process step. The cladding unit applies coating material to the substrate while the forming unit simultaneously shapes the substrate, eliminating the need for separate cladding and forming steps. This merging reduces production complexity while maintaining secure bonding between layers through the coordinated action of both units.
2Reliability
If separate steps for cladding and forming are used, then secure bonding between layers is achieved, but production time increases
Solution Approach 1:
The patent implements continuous simultaneous operation of cladding and forming processes. While the forming unit shapes the substrate continuously, the cladding unit continuously applies coating material to the substrate surface. This continuous parallel execution of both operations eliminates idle time between steps and maintains high production speed while ensuring secure bonding.
3Reliability
If hot rolling process is used for cladding, then material bonding is achieved, but process complexity and energy consumption increase
Solution Approach 1:
The patent replaces the thermal-mechanical hot rolling process with a cold-process cladding unit that applies coating material directly to the substrate. Instead of using high temperature and pressure from hot rolling, the invention uses a cladding unit with coating material application and bonding agents to achieve material bonding at lower energy consumption, maintaining bonding reliability through chemical and mechanical adhesion mechanisms.
4Productivity
If fixed layer arrangements are used in coil, then production efficiency is maintained, but flexibility in material selection and thickness ratios decreases
Solution Approach 1:
The patent implements a dynamic cladding system where the cladding unit can be adjusted during operation to apply different coating materials and thicknesses based on the specific substrate being processed. The control system allows real-time modification of cladding parameters, enabling flexible material selection and thickness ratio adjustment while maintaining continuous production efficiency, unlike fixed pre-assembled coil structures.
