Forging hydraulic press hydraulic press are generally used more frequently, for the column of the damage is relatively large, so the choice of hydraulic press when the column is also a very important parameter;
Forging hydraulic press operating frequency is high, the body stiffness is small, running fast, with incomplete statistics China's nominal pressure below 25000T hydraulic column broken or damaged nearly 100. So at the time of purchase for the column should be calculated clearly. In the calculation of column strength when the main focus on these points;
Repeated tensile stress is too large, that is generally referred to the fatigue damage, repeated to carry the place to be calculated into a long time, high strength repeated force will produce cracks;
Stress concentration area, where the bending moment is large, mainly in the connection of the beam under the nut;
Maximum load and centrifugal force; column damage will not be sudden force fracture, it is after hundreds of thousands of times repeated force, and then produce cracks, extending from the crack.
Because there is no typical load scheme, it is difficult to calculate the most effective calculation method for fatigue design. When calculating the bearing capacity of the column, a large part is based on experience, so when we elaborate to the technician, clear.
Forging hydraulic machine host part, including the fuselage, the main cylinder, the top cylinder and filling device. Power mechanism by the fuel tank, high pressure pump, low pressure control system, motor and various pressure valves and directional valves and other components. Power mechanism under the control of electrical equipment, through the pump and cylinder and a variety of hydraulic valve to achieve energy conversion, regulation and transportation, to complete a variety of process operations cycle.
Forging hydraulic cylinder: the hydraulic energy into mechanical energy Hydraulic transmission is the use of liquid pressure to transmit power and control of a transmission. The hydraulic device is composed of hydraulic pump, hydraulic cylinder, hydraulic control valve and hydraulic auxiliary element.
