Problems solved by technology
In the context of the continuous development of the manufacturing industry, the size of forgings is increasing and the complexity of workpieces is increasing, which puts forward higher requirements for the output pressure of forging hydraulic presses, and the existing tonnage hydraulic presses often cannot meet the required processing requirements.
[0005] In addition, the current hydraulic machine workpieces generate huge friction with the mold during the entire forming process. At the same time, due to the deformation resistance inside the workpiece, the forging hydraulic press not only needs to use a large pressure to complete the forging process of the workpiece, but also for complex shapes. The workpiece is also prone to the problem of insufficient forming during forging

The invention discloses a forging hydraulic machine used for performing forging and pressing machining on metal workpieces after being heated. The forging hydraulic machine comprises a bearing framework, a mold fixedly arranged on the bearing framework and used for bearing the metal workpieces, a pressing head capable of moving relative to the mold, and applying pressure to the mold so that forging and pressing machining can be performed on the metal workpieces, a hydraulic system installed on the bearing framework and used for driving the pressing head, and a shock excitation system installedon the bearing framework and capable of generating shock excitation force, so that the metal workpieces generate vibration relative to the mold in the forging and pressing machining process. Based onthis, the forging hydraulic machine at least can be used for lowering resistance to deformation in the forming process of the workpieces, and therefore the forging capacity is improved under the situation that the tonnage of the forging hydraulic machine is not changed, so that the target that the same workpieces can be machined and manufactured on a low-tonnage forging hydraulic machine is achieved, and forming of the workpieces is fuller in the forging and pressing process.
Description
technical field [0001] The present disclosure relates to the field of forging processing equipment, in particular to a forging hydraulic machine and a forging method. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. The forging hydraulic press is the main equipment for producing forgings. When the forging hydraulic press is working, it applies pressure to the heated workpiece to cause plastic deformation of the workpiece. Among them, for die forging, the main cylinder of the forging hydraulic press exerts pressure on the workpiece to cause plastic deformation of the workpiece. At this time, the pressure that the hydraulic press needs to apply mainly depends on the volume effect and surface effect of the workpiece. [0003] Among them, the volume effect describes the influence of the internal p...
