Technical Field
[0001] This invention relates to steel parts processing technology, and more particularly to an integrated processing production line, method and system for sorting and grinding ship steel plate parts. Background Technology
[0002] In the shipbuilding process, the cutting, sorting and grinding of steel plate parts are key processes. At present, many shipyards still rely heavily on manual operation in these processes. The typical operation process is as follows: after the parts are cut, they need to be manually transported and sorted or initially sorted by inefficient equipment; the sorted parts need to be transferred to the grinding station; the grinding process is mainly completed by workers using hand-held grinding tools. This manual operation mode has significant drawbacks: (1) Low efficiency: manual handling, sorting and grinding are slow and workers are prone to fatigue, which restricts the overall production efficiency. (2) Unstable quality: the quality of manual grinding depends on the experience and condition of the workers, and it is difficult to ensure consistency, especially in the grinding of complex contours or free edges.
[0003] Therefore, the industry urgently needs an integrated solution for shipyard plate cutting, sorting, and grinding that is efficient, stable, highly automated, and can overcome the limitations of existing site layouts, so as to significantly improve production efficiency, product quality, and reduce labor costs.
