Press punching device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional press punching devices face issues such as decreased manufacturing efficiency and increased costs due to manual scrap removal, potential bending of the punching jig under high pressing loads, and the risk of scraps entering the operator's bronchi, leading to accidents and product defects.
Innovation Solution
A press punching device with a reinforcing plate featuring support surface blocks and support plates at the bottom end of the punching jig to prevent bending and efficiently remove scraps, ensuring accurate punching and reducing the need for jig replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual scrap removal is used, then operating simplicity is maintained, but productivity decreases and harmful factors increase
Solution Approach 1:
The punching jig automatically removes scraps through its own structure - the through holes in the jig allow scraps to fall through during the punching process itself, eliminating the need for separate manual removal operations while maintaining continuous production flow
Solution Approach 2:
Scraps are extracted from the working area during the punching operation itself through the through holes in the jig, rather than being removed afterward. This separates the scrap removal function from manual intervention and integrates it into the punching process
2Force
If high pressing load is applied for punching, then punching effectiveness is improved, but the jig bends or twists
Solution Approach 1:
The jig is segmented into multiple structural components - the main body, the reinforcing plate with through holes, and the support structure. This segmentation allows the pressing load to be distributed across multiple points and pathways, preventing concentration of stress that would cause bending while maintaining punching effectiveness
Solution Approach 2:
The jig employs a composite structure combining the punching jig body with a reinforcing plate featuring through holes. This composite design provides both the necessary strength to withstand high pressing loads and the scrap removal functionality, achieving multiple objectives simultaneously
3Productivity
If scraps are not completely removed, then productivity is maintained, but product quality deteriorates
Solution Approach 1:
The jig's through holes automatically remove scraps during punching, ensuring complete removal without requiring additional manual operations. This self-cleaning function maintains both high productivity and perfect product quality by eliminating scrap-related defects

AI summary
A press punching device has a reinforcing plate. The press punching device includes: a punching jig configured such that a plurality of punching needles having respective through holes are coupled thereto; a reinforcing plate formed at the bottom end of the punching jig, and configured to support the punching jig; a support block formed at the bottom end of the reinforcing plate, and configured to support the reinforcing plate; a base plate formed at the bottom end of the support block, and configured to be movable in a lateral straight line; and one or more rollers configured to press a base material seated on the punching jig.
