Because the shearing force is large and the shearing frequency is high, the form generally adopts a hydraulic type or an electric flywheel type. In order to meet the requirement of shearing times, the hydraulic flying shear needs to be provided with a complex hydraulic system to improve the shearing speed and the shearing precision; the flywheel type motor needs to be provided with a complex clutch and a complex brake, meets the starting and stopping requirements, and is high in manufacturing cost. And the two reciprocating mechanisms of the flying shear usually adopt a gear rack form, and the fixed length precision can be generally controlled to be only 2-3mm due to the change of abrasion clearance in the process of repeated use.
The transverse cutting line produced in small batch is suitable for fixed length transverse cutting because of adopting discontinuous production. However, the transverse cutting scissors have a certain thickness, and in the sizing and transverse cutting process, due to the elasticity of the steel belt, the steel belt is easy to clamp the side edges of the transverse cutting scissors, and under the action of a unidirectional force, the steel belt can cause flanging along the stress direction to influence the cutting quality, and extra processing technology needs to be added to realign the flanging position.
