Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, and particularly relates to a shearing device for a longitudinal slitting machine of hot-dip galvanized sheets. Background Technique

[0002] Hot-dip galvanized sheets are mainly used in industries such as construction, household appliances, automobiles, machinery, electronics, and light industry. Common steel types of hot-dip galvanized sheets include general commodity coils, structural galvanized sheets, stamping galvanized sheets, etc. When hot-dip galvanized sheets are processed as general commodity coils, they need to be slit and cut by a slitting machine. Its longitudinal slitting machine is used to cut sheets such as silicon steel sheets, aluminum coils, and galvanized coils into several small strips along the length direction.

[0003] After retrieval, in the Chinese utility model patent publication No. CN220259703U, a shearing device for a longitudinal slitting machine of hot-dip galvanized sheets is disclosed. The adjustable shearing mechanism can be assembled by inserting, and the adjustable shearing mechanism is a separate square insertion frame. Each threaded secondary rod can be driven by the movably installed threaded secondary rod to change its position, and the interval between two cutting blades can be changed according to the longitudinal slitting and cutting requirements of hot-dip galvanized sheets, and real-time precise adjustment can be realized in cooperation with the main scale rod.
