[CN 202010759363.9] Longmen type heavy expansion forging unit
[CN 202010759363.9] Title of a gantry type heavy expansion forging unit: Application number of a gantry type heavy expansion forging unit: CN 202010759363.9 Applicant: Yantai Jisen New Material Technology Co., Ltd. Application Date: 2020-7-31 Patent Type: Invention Application The invention discloses a gantry type heavy expansion forging unit, including a body, a main driven oil cylinder on the body, a driving shaft assembly, a shaft assembly, a power output mechanism, a gantry, a turning support arm and a hydraulic servo mechanism, the driven shaft assembly and the driving shaft assembly are installed on the movable frame of the machine body and the main oil cylinder through the limiting mechanism; An auxiliary oil cylinder is installed on the gantry, and a supporting mechanism is installed on the auxiliary oil cylinder for removing or installing the mold. The overturning support arm is used to remove or install the workpiece. The hydraulic servo mechanism controls the main oil cylinder and the auxiliary oil cylinder to synchronously drive the active shaft assembly to move to realize roll forging the workpiece by the mold on the active shaft assembly; the beneficial effects of the present invention are: this solution adopts a reversible gantry to realize the processing of annular parts with a height of more than 500mm, and can completely replace the vertical expansion forging unit or the expensive horizontal expansion forging unit that can meet the processing requirements. The price is cheaper, the equipment has few external mechanisms, and the cost is lower.
