[CN 201910083983.2] Title of a closed double-point press: Application number of a closed double-point press: CN 201910083983.2 Applicant: Anhui Yuandu Machine Tool Co., Ltd. Application Date: 2019-1-25 Patent Type: Invention Application The present invention discloses a closed double-point press, including a frame on which clutch parts, slider parts, balance cylinder parts, transmission parts, guard rail parts and pneumatic pipe parts are installed, the ball head can not only drive the ball head cover to rise or fall, but also keep the ball head cover from rotating. Under the restriction of left and right reinforcing plates, the pressure head rises and falls without position deviation. During the process of rising and falling, the pressure head will drive the piston rod in the balance cylinder to expand and contract. Since the piston rod is located in the balance cylinder and connected with a sealed plate, the pressure of the balance cylinder will be reduced during the process of elongation, more and more gravity is generated on the plate, and when the ball head or other parts of the slider part are damaged, the pressure head can still be supported to avoid the pressure head falling and causing harm.
