Flexible Rolled Strip Blank Rotation for Thickness-Aligned Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of blanks from flexibly rolled strip material with variable thickness profiles is inefficient and prone to high manufacturing errors, particularly when dealing with components having end sections of different thicknesses, as existing methods struggle to accurately position and process these materials for precise cutting and shaping.
Innovation Solution
A method and system that determine the measured thickness profile of the strip material, calculate a target cutting position, and rotate the raw blanks to align their thickness profiles correctly before processing, allowing for efficient and accurate production of blanks with variable or asymmetrical thickness profiles by aligning them with the processing tool for optimal cutting and forming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cutting methods are used on flexibly rolled strip material with variable thickness profiles, then the cutting process is simple, but the manufacturing precision and positioning accuracy of blanks are poor
Solution Approach 1:
The system performs preliminary measurement of the thickness profile along the strip material before cutting, stores this data, and uses it to calculate optimal cutting positions. This preliminary action enables precise positioning of blanks without requiring complex real-time adjustments during the cutting process itself.
Solution Approach 2:
The system incorporates a measurement device that continuously monitors the thickness profile of the strip material and feeds this information back to the control unit. The control unit uses this feedback to dynamically adjust cutting positions and ensure accurate blank positioning despite variations in material thickness.
2Loss of substance
If transition ramps are rolled into the strip material between different thickness sections, then the strip can be continuously formed, but significant scrap material is generated
Solution Approach 1:
The system measures the thickness profile in advance and calculates optimal cutting positions that eliminate the need for transition ramps. By planning cuts based on pre-acquired thickness data, the system可以直接 cut between different thickness sections without requiring intermediate transition zones, thereby eliminating scrap material.
Solution Approach 2:
The system changes the cutting position parameter dynamically based on the measured thickness profile. Instead of using fixed cutting positions or requiring transition ramps, the cutting position is adjusted to match the actual thickness variations in the material, allowing direct cutting without scrap generation.
3Loss of time
If blanks with variable thickness profiles are processed without rotation, then the processing setup is simple, but the feed length and processing time are excessive
Solution Approach 1:
The system introduces dynamic rotation of blanks based on their measured thickness profiles. Blanks are rotated to optimal orientations before processing, allowing the thickest sections to be positioned favorably for the processing tool. This dynamic adjustment reduces feed length and processing time while maintaining relatively simple processing equipment.
