[0002] At present, the common bending machines on the market include mechanical type and hydraulic type. Among them, the hydraulic type bending machine mainly uses the hydraulic system to control the rise of the worktable or the pressure of the upper mold to form the sheet metal. In order to generate a large pressing force, the machine adopts the way of oil feeding into multiple cylinders during the sheet forming process, so that the workbench or upper mold has enough pressing force to form the sheet, but the process of feeding oil into multiple cylinders at the same time can produce Large pressing force, but it causes the table or the upper mold to move slowly during the upward or downward movement, thus prolonging the time for processing the sheet metal, and even in the process of debugging the equipment, it is necessary to wait for the work every time. The complete movement of the table or upper mold makes the debugging time of the equipment lengthy and extremely inconvenient in use

The invention provides an oil hydraulic system of machining equipment. The oil hydraulic system of the machining equipment comprises an oil tank, an oil hydraulic power device, a pressure regulating device, a plurality of oil hydraulic cylinders, a plurality of operating valves, an upper limit valve and a working table, wherein the working table is pushed by oil cylinders and is capable of ascending, stopping in the middle, decompressing and descending, each oil hydraulic cylinder comprises a main oil cylinder and a pair of auxiliary oil cylinders, each main oil cylinder is connected with corresponding auxiliary oil cylinders in parallel, each main oil cylinder comprises a first oil chamber and a second oil chamber, the operating valves are connected with one another in parallel, each operating valve comprises a lifting valve, a speed converting valve and a decompressing valve, the lifting valves and the decompressing valves are arranged between the main oil cylinders and the oil hydraulic power device, and the speed converting valves are arranged between the auxiliary oil cylinders and the oil hydraulic power device. Therefore, the oil hydraulic system of the machining equipment has the advantages of being fast in operation and capable of facilitating the maintenance of the equipment.
Description
【Technical field】 [0001] The invention relates to an oil pressure system of industrial processing equipment, in particular to an oil pressure system with an ascending stroke, intermediate stop, pressure release and descending stroke. 【Background technique】 [0002] At present, the common bending machines on the market include mechanical type and hydraulic type. Among them, the hydraulic type bending machine mainly uses the hydraulic system to control the rise of the worktable or the pressure of the upper mold to form the sheet metal. In order to generate a large pressing force, the machine adopts the way of oil feeding into multiple oil cylinders during the sheet metal forming process, so that the workbench or upper mold has enough pressing force to form the sheet metal, but the process of feeding oil into multiple oil cylinders at the same time can produce Large pressing force, but it causes the table or the upper mold to move slowly in the process of rising or falling, thu...
