Fine Blanking Press Handling Synchronization to Prevent Material Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fine blanking presses face issues with material bending during the processing step, leading to feeding accuracy problems, part defects, and tool damage, especially in progressive tooling, due to the fixed position of handling devices perpendicular to the material feeding direction.
Innovation Solution
Incorporating a leveling drive that synchronizes the movement of handling devices with the blanking ram, allowing them to follow the ram's direction during the fine blanking process, thus eliminating material bending and enhancing part quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If handling devices are kept fixed perpendicular to the material feeding direction, then device structure is simple, but material bending occurs causing feeding accuracy problems and part defects
Solution Approach 1:
The handling devices are transformed from fixed static structures to dynamic movable structures that can change position during operation. The leveling drives enable the handling devices to move in the vertical direction, allowing them to maintain proper alignment with the material throughout the blanking stroke, thereby eliminating material bending while preserving structural simplicity through controlled motion rather than complex fixed mechanisms.
2Reliability
If handling devices remain stationary during blanking operation, then device control is simple, but material flexion causes chipping damage on tool components
Solution Approach 1:
The handling devices are equipped with leveling drives that enable dynamic adjustment of their vertical position during the blanking operation. This dynamic capability allows the handling devices to move synchronously with the blanking ram, maintaining constant material alignment and preventing material flexion that would otherwise cause chipping damage to tool components, thereby improving reliability through controlled motion.
3Manufacturing precision
If handling devices are fixed in position, then system complexity is low, but material deformation occurs on pierced holes and coinings in progressive tooling
Solution Approach 1:
The handling devices incorporate leveling drives that enable them to move vertically in synchronization with the blanking ram during progressive tooling operations. This dynamic positioning maintains proper material alignment throughout the multi-stage blanking process, preventing deformation of critical features such as pierced holes and coinings, thereby ensuring high part quality without requiring overly complex fixed positioning mechanisms.

AI summary
A fine blanking press comprises a blanking ram and a counter unit positioned opposite the blanking ram. A press drive is configured to drive at least the blanking ram along a driving direction during a fine blanking process step. A feeding device is configured to feed a process material to a process zone defined between the blanking ram and the counter unit and at least one handling device is configured to handle the process material outside of the process zone. At least one levelling drive is configured to drive the at least one handling device in a same direction as the blanking ram during a fine blanking process step.
