Referring to fig. 1 to 3, as a preferred embodiment of the present invention, there is provided a rolling-cut type roller flying shear, which includes a frame 1, a rolling-cut roller 2, a driving device 4, and a helical gear backlash eliminating device 3.
The rolling cutting drum 2 comprises an upper drum 21 and a lower drum 23, the axes of the upper drum 21 and the lower drum 23 are parallel and are arranged oppositely, the upper drum 21 and the lower drum 23 rotate oppositely to form a rolling conveying channel between the upper drum 21 and the lower drum through clamping of the upper drum 21 and the lower drum 23, an upper cutting edge 22 is fixedly arranged on the outer circle side of the upper drum 21, a lower cutting edge 24 is fixedly arranged on the outer circle side of the lower drum 23, the upper cutting edge 22 is a curve extending structure which obliquely extends from one axial end of the upper drum 21 to the other end along the outer circle of the upper drum 21, or the extending curve of the upper cutting edge 22 is a cross-sectional line of a plane oblique to the axis of the upper drum 21 and the outer circumference of the upper drum 2, and if the outer circle surface of the upper drum 21 is unfolded in a plane, the extending curve of the upper cutting edge 22 is an oblique straight line. The lower cutting edge 24 is similar to the upper cutting edge 22, and the only difference is that the lower cutting edge 24 and the upper cutting edge 22 are oppositely inclined and rotated, and the lower cutting edge 24 and the upper cutting edge 22 are oppositely arranged. By such arrangement, when the upper roller 21 and the lower roller 23 rotate, the lower cutting edge 24 and the upper cutting edge 22 can be engaged with each other along with the rotation of the upper roller 21 and the lower roller 23, so as to cut the strip steel fed between the upper roller 21 and the lower roller 23. The steel strip is cut by the rotation of the upper roller 21 and the lower roller 23, so that the roll-cutting roller flying shear of the embodiment can be suitable for a high-speed cutting environment.
The inclination angle of the upper cutting edge 22 at the outer circle of the upper drum 21 (i.e., the inclination angle of the upper cutting edge 22 of the inclined straight line when the outer circle surface of the upper drum 21 is spread out in a plane) is 1 to 3 degrees, and the inclination angle of the lower cutting edge 24 at the outer circle of the lower drum 23 is the same. In addition, as shown in fig. 3, the angle b formed by the strip steel input between the upper roller 21 and the lower roller 23 in the direction T and the axis of the rolling cutting roller 2 is matched with the inclination angles of the upper cutting edge 22 and the lower cutting edge 24, so that the arrangement can ensure that the strip steel is cut into a rectangular shape under the condition that the floor area of the machine table is as small as possible.
