General steps of punching die:
1. Adjust the loading height of the press according to the closing height of the mold, so that the loading height of the press is slightly greater than the closing height of the mold.
2. Lift the slider to the top dead center, place the mold in the working position, and then gradually lower the slider, so that the mold handle is installed in the mold handle hole of the slider, so that the lower plane of the slider is in contact with the upper die seat, and then fix the mold handle (upper die) with a pressing block or a pressing screw.
3. The lower die is placed on the bench plate of the press, and is aligned with the upper die, and the lower die is fixed on the bench plate with the pressure plate or the pressing screw.
4, move the flywheel by hand (or choose to move, and then cut off the press power supply), so that the slider move to the bottom position, relax the adjusting screw tightening nut, turn the adjusting screw, according to the mold closing height and the upper and lower cutting edge contact requirements, adjust the slider to the appropriate position, and then lock the screw.
5, adjust the stop screw of the press punching rod device, so that the pushing action is carried out at the end of the stroke.
6, switch on the power of the press, empty stroke operation several times, and then test.
It may be because the punch mold is subjected to unreasonable force during operation or the operation is faulty, resulting in the slider itself running to the top and stuck there, unable to return to the bottom.

If the punch mold slider itself runs to the top and does not come, you can first try to check the operation of the punch mold to see if there is abnormal noise, heat or other abnormal phenomena. If an abnormal situation is found, stop the machine in time and remove the fault.

If you cannot solve the problem, seek professional technical support or contact the device manufacturer. Professional and technical personnel will check according to the specific situation and give the corresponding solution.
1. Yes, it is.
2. This may be due to the following reasons: insufficient lubrication of the punch die slider, resulting in increased friction; The parts on the slide block are damaged or loose, resulting in the slide block can not fall normally; Punch mechanical structure problem, resulting in the slide stuck.
3. If, you can check the lubrication condition first to ensure that the lubricating oil is sufficient; Check whether the parts on the slider are damaged or loose, if there is a problem, repair or replace in time; If the problem persists, it may be necessary to ask a professional to check the mechanical structure of the punch to ensure its proper operation.
There are two methods of adjustment: one for manual adjustment and the other for electric adjustment.
< br >
Manual adjustment is easy to exceed the upper limit directly hand tool to adjust it down.
< br >
If the electric modulation exceeds the upper limit, it can be returned to the middle position by forcing the contactor contact.
< br >
The electric mold adjusting slider is equipped with a digital device to control the limit of mold loading height, and the control slider can not exceed the maximum and minimum mold loading height to ensure that no accidents occur in operation.
< br >
When the range is exceeded, the one switch action of the monitor cannot be used to cut off the power supply.
< br >
If the upper limit is exceeded, the downward switch is broken, and can not be lowered, but can only be raised.
< br >
At this time, you can forcibly press the lowered contactor contact to adjust the slider to a safe range.

Pay attention to safety when operating.
