Hydraulic clamping and stretching forging machine for rod blanks

The invention relates to the technical field of hydraulic equipment, and discloses a hydraulic clamping and stretching forging machine for a rod blank. The forging machine comprises a top seat, a support, a rolling shaft, a machining rod, an ejector assembly and a clamping assembly, wherein the left side of the top seat and the right side of the support are fixedly installed, the inner wall of the support and the outer wall of the rolling shaft are movably connected, the outer wall of the rolling shaft is movably connected with the outer wall of the machining rod, and the top end of a transition plate is movably connected with the outer wall of the machining rod. According to the hydraulic clamping and stretching forging machine for the rod blank, the rolling shaft rolls to drive the machining rod to move, the machining rod arrives at the right side and moves to the top end of the ejector assembly through the transition plate, a top plate firstly makes contact with the machining rod to be matched with a structure to which the top plate belongs, so that a movable rod moves to achieve closing of a movable switch, an air pump is matched with an air pipe to enable an air pressure rod to ascend to enable the machining rod to ascend, and a guide wheel is matched to enable the machining rod to enter the inner wall of the clamping assembly to achieve clamping, so that in the process of forging machining, feeding and clamping are carried out synchronously.
