In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 and fig. 2, a novel front centering device for a rolling mill comprises a roller bed frame, a conveying device and a centering device, wherein the conveying device is used for conveying a workpiece to be processed, the conveying device is installed on the roller bed frame, and the centering device is installed above the conveying device and is close to one end of an outlet of the conveying device;

the centering devices are divided into two groups and are respectively arranged on two sides of the roller bed frame, each group of centering devices comprises a push plate 5 and a base, each base comprises a second base 6 and a third base 7, each second base 6 is provided with two strip-shaped holes, namely a second strip-shaped hole 8 and a third strip-shaped hole 9, the arrangement direction of the strip-shaped holes is perpendicular to the direction of the push plate 5, and the position of the push plate 5 in the direction can be conveniently adjusted;
