Abstract
Description
Technical Field
[0001] This invention relates to a rotary cutting device, specifically a rotary cutting device for conductor joints in submarine cable factories. Background Technology
[0002] In traditional submarine cable factories, the conductor of a joint is manually cut in a circular motion before welding. This involves manually rotating a pipe cutter. This method relies primarily on pressure to cut the conductor. While simple, it has the following drawbacks: 1. Nowadays, the conductor cross-section of submarine cables is getting larger and larger. For large cross-section cables, it is necessary to cut different layers of conductors multiple times. Traditional manual conductor cutting is inefficient. Second, the conductor of the submarine cable factory joint is currently cut manually. During the experiment, there are instances where the tool fixation is unreliable, posing a certain safety hazard. Third, this method uses manual control of the feed force of the pipe cutter. This method cannot accurately control the force, and there is a risk of cutting the lower layer of conductor when cutting the upper layer of conductor. In addition, the circular blade of the pipe cutter will swing left and right during the rotary cutting process, causing the conductor ring cut surface to be not on the same plane, which increases the difficulty of subsequent welding operations.
[0003] Fourth, manual handwheel adjustment relies on the operator's experience and feel, resulting in low precision, typically only reaching the millimeter level, which is insufficient to meet the requirements of high-precision machining. Summary of the Invention
