Press Brake Table Clamp for Hands-Free Workpiece Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional press brake operations are tedious and cumbersome, requiring significant manual effort and physical force to secure and bend metal workpieces, leading to user fatigue and potential errors in forming finished products.
Innovation Solution
A table assembly for press brake systems that includes a base and a clamp, allowing for secure placement and retention of workpieces without the need for continuous manual force, thereby reducing user intervention during the bending process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual holding of workpiece is used during press brake operation, then workpiece security and bending precision are maintained, but user fatigue increases and operation efficiency decreases
Solution Approach 1:
A clamp mechanism is introduced as an intermediary device between the user and the workpiece. The clamp securely holds the workpiece in place during bending operations, eliminating the need for manual holding while maintaining positioning precision. This mediator transfers the securing function from human hands to a mechanical device.
Solution Approach 2:
The clamp mechanism is designed to automatically secure and release the workpiece through simple user activation. Once positioned, the clamp self-maintains the workpiece security throughout the bending process without requiring continuous user intervention or physical effort, enabling the system to serve itself during operation.
2Manufacturing precision
If continuous manual force is applied to secure workpiece, then workpiece positioning accuracy is maintained, but operation efficiency and productivity decrease
Solution Approach 1:
The clamp is pre-positioned and ready to engage with the workpiece before the bending operation begins. This preliminary positioning setup eliminates the need for continuous manual adjustment during the process, allowing the operation to proceed efficiently while maintaining accurate positioning throughout the bending cycle.
Solution Approach 2:
The clamp acts as a mechanical intermediary that assumes the positioning and securing function, freeing the user to perform other tasks or prepare for the next operation. This mediator maintains positioning accuracy without requiring sustained manual force or attention.
3Ease of operation
If manual workpiece securing is used, then direct control over workpiece position is achieved, but device complexity and automation level remain low
Solution Approach 1:
The clamp mechanism serves as a simple mechanical intermediary that provides automated workpiece securing while maintaining ease of operation. The user retains direct control through simple clamp activation, but the actual securing function is performed automatically by the mechanical device, bridging the gap between manual control and automation.

AI summary
A table assembly is used to support a workpiece to facilitate bending of the workpiece. The table assembly is attached to a press brake system and include a base and a clamp. The clamp is movable relative to the base to enable placement of the workpiece onto the base, and the clamp secures the workpiece to the base to block relative movement between the workpiece and the press brake system without additional user operations. The workpiece is secured via the table assembly without a manual force (e.g., to hold the workpiece in place) while the press brake system operates to bend the workpiece. The table assembly reduces, limits, or eliminates certain user operations during metalworking. The table assembly improves user experience (e.g., reduce an amount of manual labor) and/or efficiency associated with press brake operations.
