Disclosed is a numerically controlled four-roller plate rolling machine with three linked and adjustable rollers, the plate rolling machine comprising: a base (4), two supports (1) positioned on the base (4), and an upper roller (21), a lower roller (22), a first side roller (23) and a second side roller (24) positioned between the two supports (1). The upper roller (21), the lower roller (22), the first side roller (23) and the second side roller (24) are arranged parallel to each other; the lower roller (22) is located directly below the upper roller (21); and the first side roller (23) and the second side roller (24) are located on two sides of the lower roller (22) respectively, wherein the upper roller (21) is mounted on the supports (1) and rotatably connected to the supports (1). The upper roller (21) is driven to rotate by a servo drive device for the upper roller. Two ends of the lower roller (22), the first side roller (23) and the second side roller (24) are mounted respectively to side roller linkage mechanisms (3) on two sides; the relative positions of the three rollers are invariant; and the side roller linkage mechanisms (3) on two sides are respectively connected to the supports (1) and the base (4) via lifting mechanisms (5). The numerically controlled four-roller plate rolling machine with three linked and adjustable rollers is stable in operation, favourably controllable in precise positioning, efficient and highly automated in numerical control, and can easily achieve the rolling of thin-walled cylinder workpieces having a special shape such as an elliptical or square shape, and the shaped product is of high precision and good quality.
