Research and improvement of the design scheme of the anti-stress cone cutting device for submarine cable based on TRIZ

Aiming at the low efficiency and poor quality of artificial cutting for anti-stress of submarine cable, a cutting device for the anti-stress cone of submarine cable is designed and a testing machine is made. Through the cutting experiment, it is found that the chip splashes everywhere, falls out of the device and sticks to the tool and gear, which affects the cutting accuracy. Aiming at this problem, using the method of substance-field analysis method in TRIZ, through analyzing the components of the system and establishing the functional model, the relationship between the key components is obtained. Through the reason analysis, the root cause of the problem is found. Through the substance-field analysis and the application of standard solutions, the idea of structure optimization is obtained, and a specific optimization scheme is proposed.Through the comparative experiments before and after optimization, the feasibility of the scheme is verified.
