The hydraulic press is the forging and stamping, the ramming, the swaging, the adjustment, curving, crafts and so on in powder metallurgy formation by the widespread application shaping machinery, is one of most early application hydraulic transmission machineries.Its main body generally by the rack, the hydraulic pressure (work and return trip) the cylinder part, the movement part and the guide as well as other auxiliary units is composed.
It is take the hydraulic fluid as the actuating medium, (oil pump) becomes through the power part the prime mover mechanical energy the hydraulic fluid the pressure energy, again through controls the part, then (cylinder or oil motor) trades with the aid of the functional element the pressure energy extension for the mechanical energy, the actuation load realization straight line or the gyroscopic motion, also through to controls the part remote control operation and to the current capacity adjustment, the accent decides the functional element the strength and the speed.When the outside has the perturbation to the above system, the functional element output must deviate generally the original setting, has certain error.
In the system also includes the power part, controls the part and the functional element, also is through the fat liquor transmission power.The two different spot is the hydraulic control has the positioner, the positioner function is the functional element output (displacement, speed, strength and so on mechanical quantity) feeds back with the input value (may be change, also may be constant) carries on the comparison, after the comparison deviation control system, causes the functional element the output to change or the maintenance along with the input value change is constant.It is one kind of constitution closed loop return route hydraulic actuation system, also is called the hydraulic pressure servo system or the hydraulic servo.
This article by through to the topic analysis research, searches its correlation aspect the material, and carries on the thorough analysis and the research to it, in widely absorbs other import hydraulic press merit in the foundation, the reference the international technical level of development, considered at present operation aspect and so on easy factors, to have formulated the reasonable design proposal, causes the hydraulic press to achieve one kind of new design level, reorganizes each kind of data, as well as each kind of correlation data mentioned each novel design method and the example development, enables this design to have the enough reference value.
