Punch machine works

Because the lube from the punch isn't good, friction increases, the table moves. Once the motor drives, the table doesn't move ahead, so the ball screw can establish elastic deformation, and kept in the motor deformation. The motor is constantly on the drive, the stored energy created through the elastic pressure is more than the static friction, punch table forward creep, cycle of the movement, and also the resulting crawling phenomenon. But the truth is and not the situation, a closer inspection in the situation from the lube rail, you are able to conclude that this isn't an issue. Punch crawling and vibration troubles are issues with speed. As it is the rate of the issue is to obtain the speed loop, adjust the rate from the whole process through the speed regulator to complete. ? Operation and CNC punch monitoring is performed within the CNC unit, the CNC punch brain. High precision machining, processing quality and stability multi-coordinate linkage, to process complex shape parts processing parts changes, generally only have to alter the NC program can help to save production preparation time bed itself, high precision, high rigidity, you may choose favorable Volume, high productivity (usually three to five occasions the standard machine tools).

Speed-related issues, only to discover speed regulator. Therefore, the issue of vibration from the punch can also be based in the speed regulator. You'll find the rate regulator in the following places: the first is the given signal, the first is the feedback signal, and so the Henan punch may be the speed regulator itself. ? Punch since the vibration frequency and also the motor speed includes a certain proportion, to begin with we must look into the motor is faulty, look into the brush and commutator surface conditions, and mechanical vibration, and appearance the ball bearing lube, check, don't delete all, Could be observed through the inspectors, the bearings can pay attention to the seem check ear. With no problems, we'd to determine the speed from the generator. The rate generator is generally Electricity. ? Punch Tacho Generator is really a small magnet Electricity generator whose output current ought to be linearly proportional towards the speed, that is proportional towards the output current and speed. As lengthy as there's a particular speed, its output current waveform ought to be an upright line, but because of the role of alveolar and commutator effect, the road connecting a little crossover variable. For this finish, the rate feedback circuit is put into the filter circuit, the filter circuit is connected to the AC component is reduced to current. ? The punch feedback signal is exactly like confirmed signal. Thus, there's a fluctuation from the feedback signal, which inevitably results in a speed adjuster within the other direction, so the punch vibrates.

At these times, you can easily handle, as lengthy because the motor cover is taken away punch origin, exposing a tachogenerator commutator. When don't need to inflict destruction, as lengthy because the sharp hook, carefully put each groove hook, then make use of a fine sandpaper light you to definitely help remind the burr, commutator surface after which wipe the alcohol may also be put on the carbon brush. Special attention here's, using the hook-type commutator piece cut sharp hook, don't hit volume, because very little difference, once grazing can't repair, simply to switch the winding holiday punch with alcohol. Again don't use water to rub the alcohol, so the insulation resistance cannot be reduced to dry, that will delay the repair period. ? A shut-loop system can also be because of poor parameter settings, resulting in the system oscillation, but to get rid of the oscillation of the greatest strategy is to lessen its amplification within the system adjustment 1, counterclockwise direction, you'll be able to immediately visit a significant improvement megabyte punch 2, consider the adjustable potentiometer selection of 1 is comparatively small, it sometimes are only able to be shortened, that's, the need for the feedback resistor is deleted, and also the amplification factor from the entire regulator is reduced.
