Abstract

The invention relates to the field of metallurgy pressing machines, in particular to a multifunctional combined hydraulic machine. The multifunctional combined hydraulic machine comprises a rack, a main driving cylinder, a built-in rapid driving cylinder, an auxiliary driving cylinder, a movable cross beam, a guide mechanism, a workbench, a control system, a male die and a female die, wherein the workbench is arranged at the lower end of the rack in a sliding way; the movable cross beam is arranged on the upper end of the rack and located right above the workbench; and the main driving cylinder and the auxiliary driving cylinder are connected with the movable cross beam. The action areas of piston rods of the main driving cylinder, the auxiliary driving cylinder and the built-in rapid driving cylinder are unequal, the action area of the piston rod of the main driving cylinder is maximum, and the action area of the piston rod of the built-in driving cylinder is minimum, so that when hydraulic liquid flow amounts are equal, the extension extent of the piston rod of the built-in rapid driving cylinder is maximum, and the extension extent of the piston rod of the main driving cylinder is minimum. According to the multifunctional combined hydraulic machine, under the control of a control system, the hydraulic machine is provided with different feeding speeds and can adapt to the production technology of different materials.

Description

technical field [0001] The invention relates to the field of metallurgical presses, in particular to a multifunctional combined hydraulic press. Background technique [0002] The structure of the traditional hydraulic press is divided into frame (frame, four-column, etc.), main cylinder (movable beam, guide mechanism, upper mold and lower mold, and hydraulic system. The mode of action is: the main cylinder is installed and fixed on the frame, and the movable beam The upper plane is connected with the piston rod of the main oil cylinder, and moves up and down with the extension / retraction of the piston rod, and the guiding precision is controlled by the guiding mechanism, so that the upper die and the lower die cooperate to stretch the sheet. [0003] However, for the above-mentioned traditional hydraulic press, the hydraulic system supplies oil to the main cylinder to generate the required working pressure during work, and the parts are stretched under the slow motion of the...
