[CN202110205509.X] A high-speed hydraulic press whose master cylinder stroke does not include no-load stroke
[CN202110205509.X] Title of a high-speed hydraulic press with master cylinder stroke not including no-load stroke: Application number of a high-speed hydraulic press with master cylinder stroke not including no-load stroke: CN202110205509.X Applicant: Zhou Meili Application Date: 2021-2-24 Patent Type: Application of the Invention The present invention discloses a high-speed hydraulic press with master cylinder stroke not including no-load stroke, belonging to forging equipment technical field. A vertical column is connected between the upper beam and the lower beam; a vertically arranged master cylinder is fixed under the upper beam, the lower end of the master cylinder is connected with a screw nut mechanism arranged parallel to the axis of the master cylinder, and the lower end of the screw nut mechanism is connected with a sliding block; The slide block is vertically slidably installed on the column; a balance cylinder mechanism is respectively fixed on both sides of the lower beam; the lead angle of the matching thread of the screw and nut is less than the friction angle. The invention adds a set of screw nut self-locking mechanism between the master cylinder and the slider, which can not only complete the no-load stroke of the hydraulic press, but also transmit the load on the slider that can exceed the nominal force; the hydraulic balance cylinder The mechanism eliminates the axial thread gap of the screw nut caused by gravity; the master cylinder only participates in the working load stroke of the slider and does not participate in the no-load stroke; the hydraulic press of the invention has the advantages of large opening, large nominal force stroke, high punching rate and low energy consumption.
