In daily work, how do we adjust the gap tracking during the operation of a wire-cutting machine or a Ningbo wire-cutting machine? In fact, the so-called gap tracking actually refers to the frequency conversion speed. The principle of frequency conversion does not know whether you have learned about it, so let me popularize the principle of frequency conversion in the end? The principle of frequency conversion is as follows: a discharge voltage is obtained to obtain a sampling voltage, and the voltage is used to control an oscillator whose frequency and voltage are nearly linearly changed. The pulse input by the controller directly serves as a controller operation and a feed start/stop signal. The control of the feed rate by the gap voltage is achieved. The so-called tracking tension is to artificially change the amplitude range of the sampling voltage supplied to the oscillator. The most fundamental principle of tracking adjustment is to obtain stable processing, as long as stability, speed, and smoothness are guaranteed. Since the automatic control range of the frequency conversion circuit is large, in general, the position of the frequency conversion adjustment on the panel is not very important, and it can be processed anywhere. However, in some specific cases, cutting efficiency and quality are still closely related to the high-speed conversion. The method of speed regulation is: after selecting the pulse width and the pulse, after inputting the number of tubes, observe the voltmeter and ammeter of the pulse source. The adjustment of the frequency conversion speed will make the indication value of the table change within a certain range. In the small range, the adjustment will be more sensitive, and the adjustment in the fast direction will be slower, and it is more appropriate to place it at the junction of slowness and sensitivity. It can also be said that when it is adjusted to a position that is not sensitive enough but can still be processed normally, it will be slightly adjusted back. (Ningbo wire cutting machine) This refers to the ordinary material, normal thickness. For some special materials or ultra-thick processing, the frequency conversion adjustment should be targeted. For materials with low conductivity, in addition to increasing the amplitude of the high-frequency source, the sampling start-up voltage should be increased and the tracking should be loosened. Large thickness processing should also make the frequency conversion speed slightly slower. It is better to have some no-load pulses, and also give enough time to clean the gap and restore the insulation. The tracking is too tight, which will make the discharge gap smaller, and the black and white stripes of the plating become shallower, but only the black and white color is light, and the finish is not good. Because the pits and commutating stripes are the same, they are more likely to be short-circuited. If the wire is loose or the tension is uneven, the super feed will be short-circuited for a long time, and the finish and efficiency will be gone. The tracking gap directly affects the machining of the wire cutting machine. The tracking gap is too small, and the cutting short circuit is easy to occur, and the cutting is streaked. The tracking is too loose, the tracking is not in place, and the cutting is unstable. In short, it is important to adjust the tracking gap during the wire cutting process. After reading the above article, is there a new solution to the intermediate gap when we use the wire-cutting machine or the Ningbo wire-cutting machine? When we operate, there will be many small problems and it will be difficult. Solve the problem, then at the moment when the problem occurs, do we have to solve it! Ningbo wire cutting machine is looking forward to discussing with you! ! ! Http://news.chinawj.com.cn
