Abstract

The invention relates to the technical field of press forging forming, in particular to a hydraulic machine and a wheel-hub hydraulic machine. The hydraulic machine comprises a frame, a first working table, rapid moving assemblies and a controller; the rapid moving assemblies are connected with the controller, each rapid moving assembly comprises a first power source used for driving the first working table to move and a first guide rail used for guiding the moving direction of the first working table, and the first guide rails are located on the inner wall of the frame, wherein the rapid moving assemblies are mainly used for moving the first working table, and the first working table rapidly moves up and down along the first guide rails by being driven by the first power sources. The first working table is rapidly moved to a specified position through the rapid moving assemblies, hydraulic work is conducted through the hydraulic machine, the pressing cycle time of equipment is shortened, the machine height is decreased, a huge charging pipeline and a complex charging valve are omitted, and the working efficiency is improved. The wheel-hub hydraulic machine comprises a wheel-hub mold and the hydraulic machine, the wheel-hub mold is arranged inside the frame, and compared with the prior art, the wheel-hub hydraulic machine has the above-mentioned advantages.

Description

technical field [0001] The invention relates to the technical field of press forging, in particular to a hydraulic press and a hub hydraulic press. Background technique [0002] With the rapid development of forging hydraulic press technology, the hydraulic press control technology of multi-process workbench has also been developed rapidly. Among them, the forging method of automobile wheel hub can improve its rigidity and strength, and the forging of wheel hub is also gradually popularized. A hydraulic press with a three-beam four-column frame with normal pressure oil supply. The diameter of the main cylinder of this hydraulic machine is much larger than the diameter of the hub to be forged, and the slider, liquid filling system and workbench are all large, so the machine body is very large. Huge, plus the forgings need a lot of space to take out and put in with a manipulator, so the empty stroke will be very large. Generally, the method of lengthening the main oil cylinder...
