[CN 201820155293.4] Pressure equalizing cylinder of press
[CN 201820155293.4] Title of a press equalizing cylinder: Application number of a press equalizing cylinder: CN 201820155293.4 Applicant: Foshan Douchengguang and Precision Machinery Co., Ltd. Application Date: 2018-1-30 Patent Type: Utility Model The utility model discloses a press equalizing cylinder, including a base, a piston, a stop ring, a first sealing ring, a slip ring and a cleaning ring; the piston is installed in the space formed by the stop ring and the base, and the piston can move along the length direction of the space; the first sealing ring, the sliding ring and the cleaning ring are sequentially installed from bottom to top On the piston. The beneficial effect is that the first sealing ring, the slip ring and the cleaning ring are installed on the piston. When the air cushion rises, there will be rigid contact, resulting in huge mechanical vibration and unstable oil pressure, the first sealing ring, The slip ring and the cleaning ring realize buffering, oil scraping, and cleaning; reduce noise and reduce the cracking or wrinkling of stamping parts during the mold forming process, and the structure is simple and reasonable, easy to operate, and the parts are detachable connection, easy to disassemble, high degree of versatility and interchangeability.
