Elaborate high-speed presses work cycle
    High-speed presses either punching the workpiece, and can be stamping. The system pressure different processing methods, the speed of the punch has different requirements.

    When punching, punch a speed greater whereabouts stamping parts, and rapid increase in return; while stamping process requires slider to a faster rate of decline encountered punch load (work) when the head speed is reduced and the system pressure rise high, to ensure that the steel plate stamping Huai indeed, after punching is complete, the punch at a faster rate rose back to the initial position. Work entire stamping process to achieve "in situ still → → slow down quickly return to a place quickly pressing → → Paul stopped rolling," the work cycle.

    From the above analysis shows that under different processing technology, process, the pressure of the hydraulic system requires frequent changes and adjusted for greater punching force to meet the job requirements, the system pressure requirements more Gao, general operating pressure range of 10~ 40MPa, this experimental system, the maximum hydraulic pressure is 28MPa. In addition, air travel and the compression stroke speed hydraulic punch quite different, larger oil flow in the hydraulic system, higher system power requirements, so the whole system of high-pressure flow system, the work of stability and higher security requirements.
