upper limit position: the motor (2) is started, the oil pump (3) is operated, the slide valve in the manual reversing valve is positioned at the middle position, the pressure oil discharged by the oil pump directly flows back to the oil tank, and the slide block is stopped at the original position.

Idle stroke descending: when the operating handle or the pedal is pressed, the slide valve in the manual reversing valve moves rightward, so that the pressure oil discharged by the pump enters the upper cavity of the oil cylinder, and meanwhile, the lower cavity discharges oil, and the slide block runs idle.

Working stroke: when the sliding block descends and touches the workpiece, the handle or the pedal is continuously pressed, the pressure of oil in the upper cavity of the oil cylinder is increased, and at the moment, the sliding block is shifted into a working stroke.

Backhaul: after the working stroke is completed, the hand or foot is separated from the operating handle or the pedal, and the slide valve in the manual reversing valve moves leftwards under the action of the tension spring in the operating mechanism, so that the pressure oil discharged by the oil pump enters the lower cavity of the oil cylinder, and meanwhile, the upper cavity of the oil cylinder returns, and the slide block returns.

Returning to the upper limit position: when the sliding block returns to a certain setting position, the sliding valve in the manual reversing valve is in the middle position due to the action of the collision block in the distance limiting device and the rotating arm in the operating mechanism is shifted. The pressure oil discharged from the oil pump directly flows back to the oil tank, and at this time, the slider and the piston do not sink due to the action of the support valve, and the slider stops at the set upper limit position.

The pressure of the lower cavity of the oil cylinder is stable and visualized when the main cylinder runs downwards due to the specificity of the material, wherein the pressure of the lower cavity of the oil cylinder can be regulated within 0-10 Mpa. After the workpiece is contacted, the pressure is increased from the pressure point after the setting is finished, the original pressure is changed to be increased from zero, the pressure belt of the lower cavity is ensured to be contacted with the workpiece, the workpiece is prevented from being scrapped due to overpressure, and the material correction is not allowed to be repeated more than four times (the setting is performed in the action procedure)
