[0002] Steel plate is a widely used metal material. When using some steel plates, large-sized steel plates need to be sheared into sizes that meet process requirements to facilitate subsequent processing and use. When shearing steel plates, the upper and lower slitting tools used for slitting steel plates in existing steel plate slitting machines gradually deviate during long-term operation, resulting in reduced slitting accuracy. Existing slitting machines are unable to accurately determine the offset of the upper and lower slitting tools in a timely manner, requiring the machine to be stopped for inspection, which is very cumbersome and makes the steel plate slitting machine less convenient to use.
