The invention relates to a shaping machine. The shaping machine comprises a base plate; a hydraulic cylinder and a main frame are fixedly arranged on the left side and the right side of the base platecorrespondingly; a first motor is arranged at the middle area of the main frame and is connected with a pinion, and the pinion meshes with a large gear; a convex block is welded to the front end surface of the large gear in an eccentric manner; a rocking bar is hinged to the bottom of the main frame; a middle matching groove and an upper matching groove are formed in the middle part and the upperpart of the rocking bar correspondingly; the convex block is arranged in the middle matching groove in a sliding mode; a connecting rod is arranged in the upper matching groove in a sliding mode; a driving frame arranged at the upper end of the main frame in a horizontal sliding mode is welded to the connecting rod; and a plane cutter is fixedly arranged at the left end of the driving frame. According to the shaping machine, the automation degree is high, reciprocating horizontal sliding can be carried out by controlling the driving frame and the plane cutter so that the effect of automatic planing can be achieved, and in addition, lifting and back-and-forth sliding of a clamping table is controlled so that the effects of conveniently controlling the planing volume of a workpiece and conveniently planing the whole surface of the workpiece can be achieved.
