Curved Blank Holder Profile for Fast, Precise Blank Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for mounting blanks on blank holders in milling machines are time-consuming and inefficient, requiring the removal and reinsertion of adapters and clamping screws to change blanks.
Innovation Solution
A blank holder and blank system where the blank has a guide shell on its outer edge that fits into a form-fitting profile on the blank holder, allowing for secure one-sided support and easy alignment, enabling quick and precise mounting and demounting of blanks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an adapter with clamping screws is used to fix the plastic edge, then the blank can be securely mounted, but the workflow becomes time-consuming due to repeated assembly and disassembly operations
Solution Approach 1:
The invention combines the adapter and the blank holder into a single integrated blank holder component. The receiving area is directly formed in the blank holder body, eliminating the need for a separate adapter. This merging of components allows the blank to be directly mounted on the blank holder without requiring assembly or disassembly of additional parts, thus maintaining secure mounting while significantly improving workflow efficiency.
Solution Approach 2:
The invention extracts and eliminates the separate adapter component from the mounting system. By integrating the receiving area directly into the blank holder, the patent removes the intermediary adapter that previously required assembly and disassembly operations. This extraction simplifies the overall structure and enables rapid blank changes without time-consuming operations.
2Loss of substance
If the blank is clamped at the circumferential edge, then material utilization is improved, but the plastic edge material is less pressure resistant requiring tight clamping
Solution Approach 1:
The invention applies preliminary action by pre-attaching a reinforcement element to the plastic circumferential edge before mounting. This reinforcement element, which has higher pressure resistance than the plastic material, is prepared in advance and permanently attached to the blank's edge. This allows the blank to be clamped at the circumferential edge for improved material utilization while the reinforcement element provides the necessary pressure resistance, eliminating the need for excessively tight clamping.

AI summary
A blank holder and a blank are provided, the blank holder having a receiving area for a substantially disc-shaped blank, the receiving area being curved. The receiving area forms a straight, circular or part-circular or arc-shaped form-fitting profile. The blank has a matching guide shell which can be inserted or turned into the form-fitting profile.
