I believe everyone is familiar with the shearing machine. It is a technical machine that realizes the motion control of a shearing machine or multiple shearing machines through digital instructions composed of numbers, characters and symbols; hydraulic cylinders convert hydraulic energy into Hydraulic actuators with mechanical energy and linear reciprocating motion (or swing motion). It has a simple structure and reliable work. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable. Therefore, it is widely used in various mechanical hydraulic systems. The adjustment of the hydraulic press of the shearing machine is skillful, let's take a look at it together.
One point: systematically adjust the hydraulic cylinder. When the hydraulic cylinder of the shears begins to run, the pressure of the cylinder is reduced to 0.5-1 MPa, and then when the piston rod is reciprocating, the upper vent plug is opened. The main method is to open the pressure of the vent plug when the piston finishes running, and return to the previous closed mode before the machine is ready to run. When the vent plug is exhausting, you can hear the sighing gas sound during the operation of the shearing machine, and you can clearly see that some color similar to gonorrhea foam oil is spit out, and the oil is sprayed when the exhaust begins to clarify. At this time, it can be distinguished with the naked eye whether the shearing machine is exhausted.
Two points: adjust the hydraulic buffer system device. After it is equipped with an adjustable plate bending machine damping device, the throttle valve of the running piston should be adjusted to the minimum position, and the hydraulic cylinder of the throttle plate shearing machine should be adjusted gradually to meet its requirements. The desired state.
Three points: Partially check the hydraulic cylinder of the shearing machine. In addition to the preliminary adjustment of the hydraulic cylinder, it is also necessary to check the leak tightness of the oil, and whether the bolts are loose at the connection part of the hydraulic cylinder of the shearing machine to avoid unnecessary accidents.
Fourth point: Do regular inspections. According to the normal use of the shears, the hydraulic cylinders are regularly inspected, and the inspection results of the shears are recorded in real time.
