Metal Clad Cable Cutting Machine with Notching and Segmented Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cutting flexible metal clad cables to form whips are time-consuming and require significant effort, as they often damage the wires inside the cable.
Innovation Solution
A machine is designed to efficiently cut flexible metal clad cables into whips by using a clamping assembly to secure the cable, a notching assembly to notch the metal jacket, and a cutting assembly to cut the conductors perpendicularly, allowing for precise and efficient formation of whips without damaging the internal wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional cutting methods (shearing cable cutter, hacksaw, rotary cutoff saw) are used to cut flexible metal clad cables, then the cable can be cut to length, but the internal wires are damaged and considerable time and effort are required
Solution Approach 1:
The cutting process is divided into two distinct stages: first, a notching blade cuts only the outer metal jacket to create notches, and second, a separate cutting blade cuts the internal wires. This segmentation allows each blade to perform its specific function without interfering with the other components, preventing wire damage during the jacket cutting phase while maintaining efficient overall productivity
Solution Approach 2:
The notching blade performs preliminary action by cutting the outer metal jacket before the internal wires are cut. This preliminary notching creates defined entry points and separates the jacket from the wires, allowing the subsequent cutting blade to cleanly sever the wires without dragging or damaging them through the jacket material
2Ease of manufacture
If traditional cutting methods are used, then cable cutting is possible, but considerable time and effort are required
Solution Approach 1:
The machine merges the notching function and cutting function into a single integrated device with two blades that operate in sequence. The clamping assembly secures the cable, the notching blade creates notches in the jacket, and the cutting blade severs the wires, all in one automated operation. This combination eliminates the need for multiple separate tools and manual operations, significantly reducing both time and effort while maintaining ease of operation
Solution Approach 2:
The machine performs the entire cutting operation automatically once the cable is fed and clamped. The first blade automatically notches the jacket, the cable is advanced, and the second blade automatically cuts the wires. This self-service automation eliminates manual intervention during the cutting process, reducing operator effort and time investment while ensuring consistent, precise results

AI summary
A machine forms a whip from a length of cable. The machine includes a clamping assembly, a notching assembly, and a cutting assembly. The clamping assembly includes a pad which can be move into and out of a cable travel space. The notching assembly includes a notching saw which cuts an outer jacket of the cable in a direction substantially parallel to the longitudinal axis. Movement of the pad also causes movement of the notching saw to move into the cable travel space or into a raised position. The cutting assembly includes a cutting tool which transversely cuts the conductors of the cable.
