Punch Holder Collars for Fast Height Adjustment and Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional punch assemblies require complex and time-consuming maintenance and modification processes, involving significant handling and tool usage, which can lead to wear and inefficiency in adjusting or replacing punches within punch holders.
Innovation Solution
The punch holder design features an upper and lower portion with adjustable collars that allow for height adjustment and punch release through single-action rotation, enabling quick and tool-free adjustments and replacements by utilizing linking members and retaining mechanisms for secure locking and easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional punch assemblies use fixed or complex adjustment mechanisms, then structural stability is maintained, but maintenance and modification become time-consuming and complex
Solution Approach 1:
The punch holder is divided into distinct segments: an upper portion and a lower portion that can be independently adjusted and locked. This segmentation allows maintenance personnel to access and modify specific sections without disassembling the entire assembly, significantly reducing maintenance time and complexity while maintaining structural integrity through the modular design.
2Manufacturing precision
If punch assemblies require multiple tools and handling steps for adjustment, then precise positioning is achieved, but handling complexity and wear increase
Solution Approach 1:
The punch holder incorporates self-adjusting features where the upper and lower portions can be positioned and locked without requiring external tools. The design includes self-aligning surfaces and automatic locking mechanisms that guide the adjustment process, eliminating the need for multiple handling steps and reducing mechanical wear while maintaining precise positioning through the inherent geometry of the self-locking features.
3Reliability
If punch holders use secure locking mechanisms, then reliability of punch positioning is improved, but adjustment speed is reduced
Solution Approach 1:
The punch holder design incorporates pre-positioned locking features and pre-aligned surfaces that automatically engage when the upper and lower portions are assembled. This preliminary arrangement of locking elements ensures that once the components are brought together, the locking action occurs automatically and immediately, providing reliable punch positioning without requiring time-consuming manual locking operations, thus maintaining both reliability and adjustment speed.

AI summary
Punch holders and corresponding punch configurations configured to increase the ease and speed by which maintenance and/or modification of punches used with the holders can be performed. In some cases, the punch holder (70) can be configured with one or more upper (72) and lower (74) collars operatively situated on differing areas of the holder (70), with each collar adapted to perform a different action with regard to a punch (50) held by the holder (70). In some cases, when the upper collar (72) is rotated, a corresponding height adjustment of a punch (50) held by the holder (70) results. In some cases, when the lower collar (74) is rotated, a punch (50) held by the holder (70) is released.
