Problems solved by technology
[0002] The two extrusion cylinders in the existing 100T extrusion machine are synchronously controlled by manual speed regulating valves or proportional valves. This control method not only has low synchronization accuracy, but also consumes a lot of energy in the hydraulic system, and the hydraulic oil is easy to Heat generation, which in turn leads to a reduction in extrusion quality and a reduction in overall equipment performance

The invention provides a 100T extruder hydraulic system. The 100T extruder hydraulic system comprises an oil tank, oil pumps, a left extrusion oil cylinder, a right extrusion oil cylinder, a pressing oil cylinder, an ejection oil cylinder, a left extrusion oil cylinder valve set, a right extrusion oil cylinder valve set, a pressing oil cylinder valve set and an ejection oil cylinder valve set. The oil pumps are provided with servo motors in a matched manner. The pressing oil cylinder comprises a pressing electromagnetic reversing valve, a pressing one-way valve, a pressing balance valve, a pressing balance one-way valve, a pressure releasing electromagnetic valve, an upper cavity electromagnetic valve and a safety valve. The ejection oil cylinder valve set comprises an ejection electromagnetic reversing valve, an ejection backpressure valve and an unloading adjusting electromagnetic valve. According to the 100T extruder hydraulic system, the two servo motors are adopted for driving the left oil pump and the right oil pump to synchronously control the left extrusion oil cylinder and the right extrusion oil cylinder, and synchronization precision and positioning precision are high. The amount of hydraulic oil needed by the whole hydraulic system is adjusted through the servo motors, overflow of residual hydraulic oil is avoided, and energy saving is highly achieved; and control is reliable and stable.
Description
technical field [0001] The invention belongs to the field of hydraulic control systems, and in particular relates to a hydraulic system for a 100T extruder that can improve its control stability and reduce energy consumption, and is applied to a 100T extruder. Background technique [0002] The two extrusion cylinders in the existing 100T extrusion machine are synchronously controlled by manual speed regulating valves or proportional valves. This control method not only has low synchronization accuracy, but also consumes a lot of energy in the hydraulic system, and the hydraulic oil is easy to Heat generation, which in turn leads to a reduction in extrusion quality and a reduction in the overall performance of the equipment. [0003] Therefore, in order to solve the above problems, it is an urgent problem for those skilled in the art to develop a 100T extruder hydraulic system with high synchronization accuracy and low energy consumption.
