There is no need to feed materials during debugging, but the guide screw on the guide plate should be adjusted upward first, and then the hydraulic punch hammer should be gradually adjusted to the bottom dead center by inching method. Attention should be paid to the guide plate not to press down the floating rod too low, otherwise the floating rod will be tortuous or broken. When starting the hydraulic punch feeder for continuous punching, rotate the speed adjustment screw of the feeder in a clockwise direction, and the slider will move slowly, so that it can be seen whether the slider touches the nylon washer and the length adjustment screw when it moves back and forth.
During the test machine, the sliding block moves back and forth. If it only touches the nylon gasket but does not touch the length fine-tuning screw, the floating rod does not fall deeply enough, and the guide screw on the punch needs to be slowly lowered. If the slider moves back and forth, only the length fine-tuning screw does not touch the nylon washer, this is because the floating rod drops too deeply, and the guide screw on the punch needs to be adjusted up slowly.
Hydraulic punch is a liquid (such as special hydraulic oil or water) as the working medium, through the hydraulic pump as a power source, by the force of the pump so that the liquid through the hydraulic line into the cylinder/piston, and then the cylinder/piston has several groups of seals with each other, different positions of the seal are different, but all play a sealing role, so that the liquid can not leak. After the one-way valve through the liquid in the liquid tank circulation so that the cylinder/piston cycle to do work to complete a certain mechanical action as a productivity of a machine. The use of hydraulic transmission technology for pressure processing equipment, can be used to complete a variety of forging and pressure forming.
Hydraulic punch debugging matters needing attention:
1. Wipe off the anti-rust oil and clean the whole machine.
2. Connect the cooling water.
3. Inject appropriate amount of hydraulic oil into the oil tank.
4. Turn on the power supply, and check whether the body is well grounded, close the master switch, start the motor (no oil start), pay attention to the rotation direction of the motor (according to the direction shown by the arrow on the sign)
Manual commissioning:
1. Move the automatic air switch to the ON position, and the power indicator will be on.
2, the selection switch to the manual position, press the power switch, the motor starts, wait for the motor and oil pump idling for a few minutes, observe whether the oil pump motor unit is running normally, check that there is no abnormality before the test run.
3. Press the up button, move the beam up to the dead center position, and then place the pressure test pad in the center of the workbench.
4. Press the down button to move the beam down and turn it down slowly. After pressing to the cushion cylinder, test the pressure and adjust the pressure until it is suitable.
