Problems solved by technology

The working table of the press is large, which results in a long stroke for the table to be completely moved out. In order to improve production efficiency, the moving speed needs to be increased. The precision of the press itself and the assembly precision of the mold require that the press should be stable during the movement process. The position of start and stop should be precise

Abstract

The invention relates to a hydraulic system for controlling a die forging heavy-load workbench. The hydraulic system is characterized by comprising a proportioning pump set, a starting-stopping safety valve, a direction control valve group and a workbench pushing oil cylinder which are connected successively through a pipe. The starting-stopping safety valve is composed of a YA11 electromagnetic spill valve. The direction control valve group is composed of a YA21 / 22 direction valve, a pilot operated check valve, a first spill valve, a first check valve, a second spill valve, a second check vale, a third spill valve and pressure measuring joints. By means of the technical scheme of the hydraulic system, the problems of low speed, high impact and inaccurate stopping position of a heavy press workbench during moving are solved effectively, the installation configuration is reduced, energy is saved, emission is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic systems, in particular to a control hydraulic system of a die forging heavy-duty workbench. Background technique [0002] At present, heavy-duty presses such as die forging have larger molds and larger worktables, with a load-bearing capacity of 30T-100T. Due to the limitation of motor power and installation space, oil cylinders are generally selected for drive. The working table of the press is large, which results in a long stroke for the table to be completely moved out. In order to improve production efficiency, the moving speed needs to be increased. The precision of the press itself and the assembly precision of the mold require that the press should be stable during the movement process. The position of start and stop should be precise. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a heavy-duty die fo...
