Press Brake Tool Clamping Structure for Automatic Tool Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for press brakes require complex structures with elongated holes and operation members extending vertically, leading to increased production difficulty and time, making them unsuitable for easy production and automatic change.
Innovation Solution
A tool design featuring engagement holes with circular cross-sections and anti-rotation bottomed depressed portions, such as conical or columnar holes, that allow for stable clamping and non-rotational support by a tool changer, eliminating the need for vertical operation members and elongated holes, thus simplifying production and enabling automatic change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If elongated holes and vertical operation members are used for automatic tool change, then the tool can be automatically changed, but the production time and complexity increase significantly
Solution Approach 1:
The invention extracts and eliminates the unnecessary vertical operation members and elongated holes from the tool structure. By removing these complex components, the tool can still achieve automatic change functionality through a simplified design where the tool holder directly engages with the press brake's tool installation portion, significantly reducing production time and complexity while maintaining automation capability
Solution Approach 2:
The invention adopts a simplified tool holder design that can be easily manufactured and replaced. The tool holder uses a straightforward structure with a body and tool setting portion that can be produced quickly using conventional machining methods, eliminating the need for time-consuming production of complex elongated holes and vertical operation members
2Extent of automation
If elongated holes and vertical operation members are used for automatic tool change, then the tool can be automatically changed, but the structural complexity increases
Solution Approach 1:
The invention removes the complex vertical operation members and elongated holes from the tool structure, retaining only the essential tool holder body and tool setting portion. This extraction of unnecessary components dramatically simplifies the overall structure while preserving the automatic tool change functionality through direct engagement between the tool holder and press brake
Solution Approach 2:
Instead of using complex vertical operation members to achieve automatic tool change, the invention inverts the approach by using a simplified tool holder that directly interfaces with the press brake's tool installation portion. This inversion of the conventional design philosophy eliminates structural complexity while maintaining automation capability

AI summary
A tool (10) for a press brake includes a tool main body (18), an attachment portion (20) formed on a base end side of the tool main body and configured to be detachably attached to a tool installation portion (14) of the press brake by using a tool changer (12), and a bending portion (22) formed on a distal end side of the tool main body and used to bend a plate-shaped workpiece. An engagement hole (18h) having a circular cross-sectional shape to be engaged with a bar-shaped finger (30) of the tool changer extends through the tool main body in a thickness direction. An anti-rotation bottomed depressed portion (18f) configured to receive a distal end of an anti-rotation member (34) of the tool changer is formed in a vicinity of the engagement hole.
