Hydraulic track press Drive System<\/p>\n\n\n\n

\u3000\u3000 Hydraulic track press,The drive system of hydraulic press mainly has <\/a>two types: pump direct drive and pump-accumulator drive. Pump direct <\/a>drive \u3000The pump of this drive system provides high-pressure working fluid to the hydraulic cylinder, the distribution valve is used to change the direction of the liquid supply, and the overflow valve is used to adjust the system’s limited pressure, and at the same time plays a role of safety overflow. This kind of drive system has few links and simple structure. The pressure can be automatically increased or decreased according to the required working force, reducing electric energy consumption, but the capacity of the pump and its driving motor must be determined by the large working force and high working speed of the hydraulic machine. This type of drive system is mostly used in small and medium hydraulic presses, but also a large (such as 120,000 kN) free forging hydraulic press directly driven by a pump.<\/p>\n\n\n\n

\u3000\u3000Pump-accumulator drive \u3000There is one or a group of accumulators in this drive system. When the high-pressure working fluid supplied by the pump has a surplus, it is stored by the accumulator; when the supply is insufficient, it is supplemented by the accumulator. With this system, the capacity of the pump and the motor can be selected according to the average consumption of the high-pressure working fluid, but because the pressure of the working fluid is constant, the electric energy consumption is large, and the system has many links and the structure is more complicated. This kind of drive system is mostly used for large hydraulic presses, or a set of drive system drives several hydraulic presses.<\/p>\n\n\n\n

  Tipo de estrutura<\/p>\n\n\n\n

According to the direction of the force, there are two types of hydraulic presses: vertical and horizontal. Most hydraulic presses are vertical, and hydraulic presses for extrusion are mostly horizontal. According to the structure type, the hydraulic press has two-column, four-column,eight-column, welded frame and multi-layer steel belt winding frame, etc., and medium and small vertical hydraulic presses also use C-frame type. The C-frame hydraulic press is open on three sides, which is easy to operate, but has poor rigidity. The welding frame hydraulic press used for stamping has good rigidity, open front and rear, but closed left and right. In the vertical four-column free forging hydraulic press with upper transmission, the oil cylinder is fixed in the upper beam, the plunger is rigidly connected with the movable beam, and the movable beam is guided by the column and moves up and down under the pressure of the working fluid. There is a workbench that can move back and forth on the beam. The upper anvil and the lower anvil are respectively installed under the movable beam and on the work surface. The working force is borne by the frame composed of upper and lower beams and columns. Large and medium free forging hydraulic presses driven by pump-accumulators often use three working cylinders to obtain three levels of working force. A balance cylinder and a return cylinder that exert upward force are also arranged outside the working cylinder.<\/p>\n\n\n\n

Main classification<\/p>\n\n\n\n

\u3000\u3000Hydraulic track press,According to the structural form, it is mainly divided into: four-column type, single-column type (C type), horizontal type, vertical frame, hydraulic press, etc. is mainly divided into metal forming, bending, stretching, punching, powder (metal, non-metal) forming, press fitting, extrusion, etc. according to the purpose.<\/p>\n\n\n\n

\u3000\u3000Hot Forging Hydraulic Press<\/p>\n\n\n\n

\u3000\u3000 Hydraulic track press,Large hydraulic forging press is a forging equipment that can complete various free forging processes, and is one of the widely used equipment in the forging industry. There are currently 800T, 1600T, 2000T, 2500T, 3150T, 4000T, 5000T and other series of hydraulic forging presses.<\/p>\n\n\n\n
