The invention discloses a shaper. According to the technical scheme, the shaper is characterized in that the shaper comprises a machine frame; and a feeding and transferring device, inner diameter and outer diameter shaping devices, outline shaping devices, a discharging and transferring device and transferring devices are arranged on the machine frame, wherein, the feeding and transferring device is used for feeding and transferring products; the inner diameter and outer diameter shaping devices are used for shaping the outer diameters of the products and comprise inner diameter broaching mechanisms and outer diameter shaping mechanisms, the inner diameter broaching mechanisms are used for being inserted into branch pipes of the products correspondingly, and the outer diameter shaping mechanisms are used for allowing the branch pipes of the products to be inserted into correspondingly; the outline shaping devices are used for shaping outlines of the products and comprise pressing molds for shaping the products through a pressing action correspondingly; the discharging and transferring device is used for discharging and transferring the products; and the transferring devices are used for delivering the products in the shaping process and transferring the products to the inner diameter and outer diameter shaping devices, the outline shaping devices and the discharging and transferring device from the feeding and transferring device correspondingly. The shaper solves the problems that in the prior art, manual shaping of the products like stop valves is low in efficiency, wastes labor force and increases cost.
