The invention discloses rib-bulging equipment for a steel tube. The rib-bulging equipment for the steel tube comprises a female mould and a male mould. The female mould comprises a left female mould and a right female mould, wherein the left female mould is fixedly connected with the right female mould in a detachable mode, the left female mould and the right female mould are respectively provided with a semi-circular notch, when the left female mould is fixedly connected with the right female mould, the two semi-circular notches are sealed to form a pipeline exactly which is matched with the external form of a steel tube which needs rib bulging, and the semi-circular notch of the left female mould and the semi-circular notch of the right female mould are respectively provided with a ring form bulging rib groove 5 in a matching mode. The male mould is of a cylinder shape, and a ring form bulging rib protrusion 6 matched with the ring form bulging rib groove is arranged on the outer side face of the male mould. A power device is additionally arranged in the rib-bulging equipment for the steel tube, and the power device can drive the female mould to move along the axial direction of the male mould and to move along the circumferential direction of the inner side face of the steel tube which needs rib bulging separately or simultaneously. According to the rib-bulging equipment for the steel tube, steel tube bulging ribs can be modeled at one time, and thus not only is efficiency improved greatly, but also quality is stable.
Description
Technical field [0001] The invention relates to a bulging equipment for steel pipes. Background technique [0002] The oil return pipe is generally formed of steel pipe with convex ribs. For the convex ribs, metal processing pipe ends are generally used at present, and there is no special reinforcement equipment, which is not only inefficient, but also unstable in quality. Summary of the invention [0003] In order to overcome the above-mentioned drawbacks, the present invention provides a bulging equipment for steel pipes, which can form steel pipe ribs at one time, which not only greatly improves efficiency, but also stabilizes quality. [0004] The technical solution adopted by the present invention in order to solve its technical problems is: a bulging equipment for steel pipes, including a female die and a male die, the female die includes a detachable and fixedly connected left and right female die, the left The concave mold and the right concave mold are respectively provide...
