What are the characteristics and applicable scenarios of oblique-edge shears and flat-edge shears?

The upper and lower blades of the inclined blade shearing machine are at a certain angle. Generally, the upper blade is inclined, and the inclination angle is usually 1° to 6°. Its shearing force is smaller than that of the flat blade shearing machine, and the motor power and the weight of the whole machine are greatly reduced. It is the most widely used in actual applications and is suitable for shearing of most metal plates. The upper and lower blades of the flat blade shearing machine are parallel to each other, with good shearing quality and small distortion, but the shearing force is large and the energy consumption is large. It is often used in steel mills for hot shearing of initial rolled square billets and slabs and other occasions with extremely high shearing quality requirements.
