Solution Overview
Problem
Existing shearing apparatuses face issues with imprecise unwinding and stabilization of materials on the cutting table, leading to inefficient material usage and instability during cutting, particularly when dealing with multiple layers.
Innovation Solution
The apparatus employs a dual-clamp system with hydraulic or pneumatic actuation for precise locking and stabilization, combined with a motor-driven belt system for accurate advancement of the material, allowing for the simultaneous handling of multiple layers without layer movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual unwinding operation is used, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The system uses automatic unwinding control where the programmable controller autonomously manages the unwinding process based on stored cutting patterns and material length requirements, eliminating manual operation while ensuring precise material advancement
Solution Approach 2:
The system incorporates sensors and measurement devices that monitor material unwinding in real-time, providing feedback to the programmable controller to adjust and maintain precise positioning of the material on the cutting table
2Ease of operation
If suction systems are used for stabilization, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The system employs pneumatic suction devices with adjustable vacuum pressure to firmly hold the material on the cutting table, providing reliable stabilization that prevents material movement during cutting operations while remaining easy to activate and control
3Reliability
If single layer cutting is used, then reliability is improved, but productivity deteriorates
Solution Approach 1:
The system divides the cutting process into separate operations for different material layers, with the ability to independently position and cut each layer using multiple cutting heads that can operate simultaneously on different layers without compromising cutting stability
Solution Approach 2:
The system combines multiple cutting heads and layer positioning mechanisms into a single integrated system, allowing simultaneous cutting of multiple material layers while maintaining the reliability of stable material positioning through the pneumatic suction system

Function Achieved in This Case
This solution ensures precise and efficient cutting of materials, including multiple layers, by maintaining material tension and stability, thereby optimizing material usage and reducing production costs and time.
Implementation Method 1
The clamp is effective for ensuring stable positioning of the material to be sheared on the cutting table, thanks to the friction acting on the surface of the material itself
