Description

Technical Field

[0001] The utility model relates to the technical field of steel plate shearing, in particular to a length-fixing device for steel plate shearing. Background Art

[0002] Steel coil, also known as coiled steel. Steel is hot-pressed or cold-pressed into a coil shape for easy storage and transportation, and for various processing, such as processing into steel plates, steel strips, etc. When existing steel coils are sheared into steel plates, the steel coils are flattened and conveyed by the steel plate conveyor until they come into contact with the abutment plate, and then the press is manually pressed to cut it off by the switch, and the steel plate conveyor stops conveying the steel plate. This method reduces production efficiency, and when steel plates of different lengths are required, the bolts fixing the abutment plate on the bracket are removed, and the abutment plate is moved to the required position before the bolts are tightened. The operation is complicated and there are shortcomings. Utility Model Content
