[CN 201821381930.6] Pressure Pin Adjustment Device for Hot Die Forging Press
[CN 201821381930.6] Hot Die Forging Press Pressure Pin Adjustment Device Title: Hot Die Forging Press Pressure Pin Adjustment Device Application Number: CN 201821381930.6 Applicant: Erzhong (Deyang) Heavy Equipment Co., Ltd. Application Date: 2018-8-24 Patent Type: Utility Model The utility model hot die forging press pressure pin adjustment device belongs to the field of die forging equipment, and aims to improve the reliability of the compression bow to brake the pressure pin. It includes a lock block matched with the compression bow, a pin shaft that supports the lock block and slides with the lock block, and also includes a hydraulic cylinder, a piston rod, a piston and a support; the hydraulic cylinder is installed on the support; the piston is arranged in the hydraulic cylinder One end of the piston rod is connected with the piston, and the other end is hinged with the lock block; the inner cavity of the hydraulic cylinder is divided into an upper cavity and a lower cavity by the piston, and the hydraulic cylinder is provided with a liquid inlet 1 communicating with the upper cavity and a liquid inlet 2 communicating with the lower cavity; in the lower cavity of the hydraulic cylinder, one end is arranged against the bottom of the hydraulic cylinder and the other end is against the piston compression disc spring. In the utility model, in the process of locking the pressure pin by pressing the bow, the relative position of the piston rod is locked by the back pressure of the compression disc spring, and the relevant hydraulic station is not required to work continuously, so that the clamping of the pressure pin by the pressing bow is stable and reliable.
