Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional turret punch presses face limitations in handling various processes due to dedicated tooling, leading to reduced versatility, chip entanglement issues, and inability to detect tap overstroke, which can result in tool damage.
Innovation Solution
An adapter for tapping with ring gears and a gear holder allows for versatile tool mounting, a tap die with a plate-like contact member and curved surface prevents chip entanglement, and a fluid sensor detects tap overstroke by monitoring air supply changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If dedicated mounting sections for punches and tapping tools are used in turret punch press, then tool mounting stability is improved, but tooling versatility deteriorates
Solution Approach 1:
The patent applies universality by designing a unified mounting section that can accommodate both punches and tapping tools. The mounting section includes a clamp mechanism that can securely hold different tool types, and the turret is configured to rotate and position various tools at the working position. This eliminates the need for separate dedicated mounting sections while maintaining stable tool mounting through the standardized clamp structure.
2Reliability
If conventional tap die structure with inner cylinder is used, then tap contact function is improved, but chip discharge performance deteriorates
Solution Approach 1:
The patent applies curvature by replacing the conventional inner cylinder with a curved surface structure. The tap contact member features a curved surface that guides chips away from the tap die interior, preventing entanglement. The curved geometry naturally directs chip flow along the tapping operation, improving discharge performance while maintaining the tap contact function through the curved contact surface.
3Device complexity
If no overstroke detection mechanism is implemented, then device complexity is reduced, but tool damage risk increases
Solution Approach 1:
The patent implements feedback through a sensor system that monitors tap stroke position during operation. The sensor detects when the tap reaches its predetermined stroke limit and provides feedback signals to the control system. This enables automatic detection of overstroke conditions, allowing the system to prevent tool damage by stopping or alerting the operator before excessive stroke occurs, while maintaining relatively simple device architecture through integrated sensor feedback.

AI summary
A tapping tool is mountable on an adapter for tapping. The adapter includes a ring gear in which the tapping tool is mountable; and a gear holder in which the ring gear is disposed and which is mountable on a turret of a turret punch press so as to locate the disposed ring gear at a position corresponding to a punch mounting section formed in advance in the turret. The tapping tool includes a cylindrical body and a rotating body.
