[CN 202111507961.8] A Toggle Type Precision Cold Forging Machine and Its Die Forging Method Title: A Toggle Type Precision Cold Forging Machine and Its Die Forging Method Application Number: CN 202111507961.8 Applicant: Zhejiang Jingyong Precision Forging Machinery Co., Ltd. Application Date: 2021-12-10 Patent Type: Invention Application The present invention belongs to the technical field of die forging machines and discloses a toggle type precision cold forging machine, it includes a body, a guide column, a lower mold and an upper mold. The right side of the inner wall of the body is movably hinged with an oil cylinder, the telescopic end of the oil cylinder is fixedly installed with a connector, and the inside of the connector is movably hinged with a support rod and a transmission rod. The bottom end of the transmission rod is movably connected with a moving plate through a connector, and the top end of the support rod is movably connected with a support plate through a connector. In the present invention, the contact column drives the connecting rod to rotate during the movement process, thereby driving the moving block and the magnet to move down synchronously. When the spring is compressed to the limit, the distance between the two is just enough for the fixed distance of magnetic attraction, so that the impact inertia of the oil cylinder is After the spring is absorbed, the dynamic force balance with the spring is maintained through the magnetic attraction fixing force between the magnet and the transmission column, so as to prevent the spring from rebounding quickly after absorbing energy, maintain the stability of the upper and lower dies during processing.
