Punch Die Retainer Collar Height Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing punch die designs require complex machining and multiple steps to maintain the screwing relation between the punch head and body after sharpening the edge portion, increasing the number of machining steps and complexity.
Innovation Solution
A punch die design featuring a punch body with a key and a retainer collar that includes an engaging projection portion capable of passing through the keyway and engaging with a peripheral slot on the punch guide, simplifying the construction and machining by allowing the retainer collar to be rotated relative to the punch guide for height regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a keyway and communication slot are independently machined on the punch guide, then the retainer collar can be engaged and disengaged, but the number of machining steps increases and machining complexity increases
Solution Approach 1:
The patent combines the keyway and communication slot into a single integrated structure on the punch guide. The keyway is designed to serve dual purposes: guiding the key for rotational positioning and serving as the communication slot for engaging/disengaging the retainer collar. This merging eliminates the need for separate machining operations for both features, reducing machining steps and complexity while maintaining the engagement functionality.
Solution Approach 2:
The keyway is designed with multi-functionality, serving both as a rotational guide for the key and as a communication slot for the retainer collar engagement. By making the keyway universal for both purposes, the patent reduces the number of separate components and machining operations required, thereby simplifying the overall structure and manufacturing process.
2Adaptability or versatility
If the retainer collar is rotated relative to the punch guide for height regulation, then height adjustment is achieved, but the screwing relation between punch head and body must be regulated
Solution Approach 1:
The patent employs a dynamic adjustment mechanism where the retainer collar can be rotated relative to the punch guide to change the height position. The screwing relation between the punch head and body is designed to be adjustable through this rotation, allowing the system to adapt to different height requirements while maintaining proper engagement through the key-way-key mechanism during the adjustment process.
3Stability of the object's composition
If the punch body fits in the punch guide with a key for rotational prevention, then positional stability is achieved, but the structure becomes more complex compared to simple fitting
Solution Approach 1:
The patent introduces a key as an intermediary element that fits into a keyway on the punch guide. This key serves as a mediator to prevent rotational movement of the punch body while maintaining a relatively simple fitting structure. The key-way-key mechanism provides rotational constraint without requiring complex interlocking structures, achieving positional stability through a straightforward intermediate component.

Function Achieved in This Case
This design simplifies the assembly and disassembly of the punch die, reduces machining complexity, and allows for easier height regulation of the punch edge portion, preventing unintentional disengagement of the punch body from the guide.
Implementation Method 1
an elastic member interposed between the punch head and the retainer collar to bias the punch driver upward along the axis

AI summary
A punch die is provided and includes a punch body extending along an axial direction of the punch die and including a punch edge portion, a key, and a punch driver. The punch die also includes a punch guide configured to removably receive the punch body therein, the punch guide including an inner hollow that receives the punch body and a keyway that receives and guides the key. The punch die further includes a retainer collar detachably coupled to the punch guide and configured to permit the punch driver to pass therethrough and be movable along the axial direction. The punch guide includes a peripheral slot that intersects the keyway of the punch guide and the retainer collar includes a cylindrical projection and an engaging projection that is rotatable to engage the peripheral slot and to be releasably aligned with the keyway.
