Embodiment 1
[0034] When the three groups of side hydraulic cylinders 5, 5' and 9, 9' and 10, 10' are evenly distributed on the circle centered on the central axis of the main hydraulic cylinder 4, and the three groups of side hydraulic cylinders 5, 5' and 9, 9 When the output pressure of ' and 10, 10' are the same, the combination is as follows:
[0036] b. Select two hydraulic cylinders as pressure cylinders for pressing down, and the option is any group of side hydraulic cylinders (such as: 5, 5' or 9, 9' or 10, 10');
[0037]c. Select three hydraulic cylinders as pressure cylinders for pressing down. Option 1 is to select any group of side hydraulic cylinders (such as: 5, 5' or 9, 9' or 10, 10') to combine with the main hydraulic cylinder 4, Option two is three side hydraulic cylinders whose central axis forms a regular triangul...
Embodiment 2
[0043] When the three groups of side hydraulic cylinders 5, 5' and 9, 9' and 10, 10' are randomly distributed on different circles with the central axis of the main hydraulic cylinder 4 as the center, and the three groups of side hydraulic cylinders 5, 5' and 9, When the output pressure of 9' and 10, 10' is different, the combination is as follows:
[0044] a. Select a hydraulic cylinder as the pressure cylinder for pressing down, and select the main hydraulic cylinder 4 as the working pressure cylinder;
[0045] b. Select two hydraulic cylinders as the pressure cylinders for pressing down, and the option is a group of side hydraulic cylinders (such as: 5, 5' or 9, 9' or 10, 10');
[0046] c. Select three hydraulic cylinders as the pressure cylinders for pressing down. The option is to select any group of side hydraulic cylinders (such as: 5, 5' or 9, 9' or 10, 10') to combine with the main hydraulic cylinder 4;
[0047] d. Select four hydraulic cylinders as the pressure cyli...

Abstract
The invention relates to a multi-cylinder hydraulic forgingmachine and combined distribution of cylinders. Different forging pressures are obtained through multi-cylinder distribution and different combinations of the hydraulic cylinders, through organic cooperation of multi-cylinder arrangement of the hydraulic forgingmachine and a valve control device, the situation that the hydraulic forgingmachine combines and distributes combined arrangement of the corresponding hydraulic cylinders according to the resistance magnitude is achieved, and the purpose that output pressure is matched with rolling resistance of a rolling machine is achieved. The problem of energy losses under the mode that an energy accumulator is adopted to independently provide power oil for the hydraulic forging machine is solved by the multi-cylinder hydraulic forging machine and combined distribution of the cylinders, and accordingly technical guarantees are provided for promotion of the mode that the energy accumulator provides the power oil for the hydraulic forging machine independently. The design thought is unique, the distribution variation of the hydraulic cylinders is large, the application range iswide, and the multi-cylinder hydraulic forging machine has the advantages that the pressure building speed is high, and energy is saved.
Description
technical field [0001] The invention relates to a hydraulic forging machine provided with a plurality of hydraulic cylinders, in particular to a method for arranging hydraulic cylinders when all or part of the hydraulic cylinders are in use, and belongs to the technical field of hydraulic transmission. Background technique [0002] Hydraulic forging machine is a new type of forging equipment. Due to its advantages of high automation, good control precision and saving raw materials, it is the first choice of high-end forging industry at home and abroad. It is widely used in machinery manufacturing and forging of high-quality and high-performance materials. At present, domestic better hydraulic forging machine components are designed and manufactured according to the international advanced level, and the key components are imported foreign famous brand products, so the equipment cost is very expensive. Due to the large energy consumption of the forging machinery, especially th...
