G. when the upper conveying roller (2) and the lower conveying roller (3) accelerate to a constant speed, and the fixed block (7) also drives the upper cutting mechanism and the lower cutting mechanism to accelerate to the constant speed, the steel plate is fed according to the feeding speed, is fed at the constant speed under the action of the upper conveying roller (2) and the lower conveying roller (3) and is cut at the constant speed under the action of the upper cutting mechanism and the lower cutting mechanism, and therefore a cutting seam with a certain angle is formed under the combined action of feeding at the constant speed and cutting at the constant speed.
