Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and more specifically, to a hull cutting device for go-kart production. Background Technology

[0002] In the go-kart manufacturing industry, hull construction typically involves the precise cutting of various types of plates to meet the design specifications of different parts of the hull.

[0003] Currently, most common ship hull plate cutting devices use saw blades as the cutting tool. However, existing cutting devices have significant shortcomings in saw blade protection. While the main saw blade guard can protect operators from accidental injury to some extent, it cannot provide comprehensive and effective protection when the saw blade is not in use, such as during the transfer of the cutting device. The saw blade is easily damaged by collisions and scratches during transfer. Therefore, we have made improvements and proposed a ship hull cutting device for go-kart production.
