Wire Stripping Blade Layout Without Lateral Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical wire processing devices require significant effort and time to strip the covering of electrical wires due to the need for moving the wire left and right during the stripping process.
Innovation Solution
An electrical wire processing device equipped with cutting blades, slit blades, and actuators that allow for simultaneous cutting and efficient stripping of the wire covering without requiring perpendicular movement, using a clamp member and controller to automate the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical wire is moved left and right to perform the stripping process using cutting and notch cutters, then the covering can be stripped, but the operational time and effort increase significantly
Solution Approach 1:
The device divides the stripping function into two separate components: cutting blades for circumferential notching and slit blades for longitudinal slitting. This segmentation allows each blade type to be optimized for its specific function and eliminates the need to reposition the wire for different operations
Solution Approach 2:
The invention introduces slit blades that operate in a different dimensional approach by cutting along the longitudinal direction of the wire, complementing the circumferential notching of the cutting blades. This multi-dimensional approach to cutting eliminates the need for wire repositioning
2Device complexity
If cutting and notch cutters are used for both cutting and circumferential notching, then device complexity is reduced, but the stripping process requires wire repositioning which reduces productivity
Solution Approach 1:
The device merges the cutting and notching functions into a single operational sequence by positioning both cutting blades and slit blades along the wire's longitudinal direction. This allows both functions to be performed without wire repositioning, maintaining operational efficiency while enhancing productivity
Solution Approach 2:
The cutting blades perform circumferential notching at specific positions before the slit blades perform longitudinal slitting. This preliminary action sequence is established in advance, allowing continuous processing without wire repositioning and thereby improving productivity

AI summary
An electrical wire processing device (1) includes a pair of cutting blades (40A, 40B) capable of cutting an electrical wire (5) and circumferentially notching a covering (5b), a slit blade (43A, 43B) disposed farther in one side in a longitudinal direction (CL) of the electrical wire (5) than the cutting blades (40A, 40B) and capable of slitting the covering (5b) in the longitudinal direction (CL) of the electrical wire (5), and a slit blade actuator (35A, 35B) that moves the slit blade (43A, 43B) between a slit position in which the slit blade (43A, 43B) comes closer to the electrical wire (5) than the cutting blades (40A, 40B) and a retraction position in which the slit blade (43A, 43B) goes farther from the electrical wire (5) than the cutting blades (40A, 40B).
