2D Stirrup Machine mechanism works

        CNC 2D Stirrup Machine mechanism works: cut off in the middle of the center of the piston is provided with a spool and spring, at idle, due to the action of the spring, leaving the middle of the center pillar river hole cylinder, high-pressure oil from this hole through the eccentric shaft oil passage back into the tank. When 2D Stirrup Machine cut, in order to push the piston manpower, 'the central spool blocked the center hole cylinder, this time coming from the high-pressure piston pump oil through the inlet valve into the cylinder, resulting in high pressure pushes the piston movement, the piston driven cutter for cutting steel. When the pressure of the spring effect is greater than the thrust reverser inner cylinder pressure, the spool will return to the original position, oil flows back into the tank along the central hole of the oil. Cut off the return of the piston, relying on the plate spring return force to achieve.
