The non-metallic inclusions in the steel after hot rolling are pressed into thin slices, and the phenomenon of delamination occurs, which greatly deteriorates the tensile properties of the steel in the thickness direction, and cracks are prone to appear during shearing. The trimming machine provided by BOYA uses sharp blades and precisely controls the cutting edge clearance. Therefore, we controlled the maximum tensile stress at the tearing junction, the main external cause of steel plate cracking, to a reasonable range.
High-strength steel and ordinary steel
The single-side shearing knife box of the disc shears is for one use and one preparation and can be quickly switched through the rotary mode so that the unit can quickly change the tool without stopping the machine.
The disc cutter is equipped with a tool change and maintenance platform, which can realize online tool change and maintenance of the spare tool box.
The disc knife adopts the end face grinding method, the hydraulic nut is locked, the upper knife adopts the front rigid positioning, and the lower knife adopts the rear rigid positioning, which can greatly improve the convenience of equipment operation and maintenance and reduce the ineffective consumption of spare parts.
Equipped with cutter cleaning device and scraper mechanism, it can guarantee and prolong the service life of the disc blade.
Electromechanical and hydraulic control integrated products, equipped with reliable Siemens control system and optimized process adjustment template, boya equipment can effectively ensure stable product quality.
