Automatic Indentation Marking Die for Deep Metal Workpiece Stamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current metal workpiece marking methods, such as laser marking and indentation, face issues with low automation and aesthetically unpleasing shallow marks that can be obscured by painting, while indentation marking lacks automation and is prone to manual error.
Innovation Solution
A metal workpiece indentation marking device featuring an automatic marking die with a character switching mechanism, scale locking mechanism, and two-dimensional moving mechanism, allowing for fully automated character arrangement and simultaneous stamping of multiple characters without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If laser marking method is used, then automation degree is high, but the mark trace is shallow and aesthetic quality is poor
Solution Approach 1:
The patent replaces the laser marking system (optical/thermal field) with a mechanical indentation marking system. The striking head with marking die mechanically stamps characters onto the workpiece surface, creating deep physical impressions that are both aesthetically pleasing and resistant to subsequent painting processes, while maintaining high automation through the automated feeding and positioning system.
2Shape
If manual character arrangement is used in indentation marking, then mark depth is sufficient, but automation degree is low and manual errors occur
Solution Approach 1:
The patent implements preliminary action by pre-arranging multiple character dies in the marking die assembly according to the required character sequence. The automated feeding system pre-positiones the workpiece, and the system automatically selects and positions the correct character die before the stamping operation, eliminating manual character arrangement and preventing human errors while maintaining deep indentation marks.
Solution Approach 2:
The marking system performs self-service through automated character selection and positioning. The control system automatically determines which character die to use based on the required information, and the mechanical structure automatically positions the correct die in the striking head, eliminating the need for manual intervention in character arrangement while ensuring accurate and consistent marking depth.
3Device complexity
If manual character arrangement is used, then device complexity is low, but manufacturing precision is poor due to human error
Solution Approach 1:
The patent replaces the simple manual character arrangement mechanism with an automated mechanical selection system. Multiple character dies are mechanically positioned in the marking die assembly, and the control system mechanically actuates the selection of the correct die based on the required character, ensuring precise character arrangement without human error while maintaining reasonable device complexity through mechanical automation.
