Punching Machine Frame Mechanism for Precision Perforation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing punching and perforating machines have limitations in producing small grid dimension patterns due to large needle spacing, resulting in low needle density per unit area and low cycle rates, leading to inefficient processing times and increased wear, which complicates the production of precise and varied perforation patterns.
Innovation Solution
A punching and perforating machine with a frame device that securely holds the material unit, allowing for precise positioning and movement in both the transport and transverse directions, using servo motors and piston-cylinder units for controlled perforation, enabling the production of complex patterns without mechanical constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If large needle spacing is used in punching/perforating machines, then device complexity is reduced, but manufacturing precision deteriorates due to inability to produce small grid dimension patterns
Solution Approach 1:
The patent implements a movable frame device that can be dynamically repositioned in both transverse and transport directions, allowing the same physical needle arrangement to produce varied perforation patterns through controlled movement rather than requiring multiple fixed needle arrays
Solution Approach 2:
The frame device serves multiple functions: it holds the material unit, enables positioning in two directions, and works with a single needle array to produce multiple different perforation patterns, replacing what would traditionally require multiple specialized tooling setups
2Reliability
If low cycle rate is used in punching machines, then reliability is improved, but productivity deteriorates due to inefficient processing times
Solution Approach 1:
The patent employs periodic reciprocating movement of the frame device between stations, with controlled acceleration and deceleration phases, enabling high cycle rates while maintaining reliable operation through predictable periodic cycles rather than continuous high-speed operation
Solution Approach 2:
The processing system is divided into multiple stations with the frame device moving between them, allowing parallel operations and reducing overall cycle time while maintaining reliability at each individual station
3Ease of operation
If material unit is not securely held, then ease of operation is improved, but manufacturing precision deteriorates due to positioning inaccuracies
Solution Approach 1:
The frame device provides a standardized interface and positioning system that creates equivalent positioning conditions for different material units, ensuring consistent precision across various materials while maintaining ease of operation through uniform loading procedures
