Description

technical field [0001] The invention relates to a chip, in particular to a digital integrated pulse power supply chip used in the field of fast wire and medium wire electric discharge cutting. Background technique [0002] With the rapid development of my country's economy, military industry, mold industry and special material application industry, EDM technology has also developed rapidly. Among them, CNC wire cutting is the fastest growing and most widely used machine tool. [0003] In the 1970s, my country's scientific and technological personnel independently innovated and developed the fast wire cutting machine tool. Compared with foreign slow wire cutting machine tools with high precision, high manufacturing cost and high use cost, it has a large market demand, low sales price, and daily use. Three major advantages of low consumption cost. Moreover, in recent years, the annual output of such machine tools in my country has maintained a high-speed increase. Mainly used...

AI Technical Summary

Problems solved by technology

[0004] Most of the fast-moving wire cutting machines in the prior art use analog pulse power supply, which has a single pulse type, unstable signal source, and poor anti-interference ability.

[0005] 1. It has a single function and can only generate and output pulse waves of a single type and pulse width range;

[0006] 2. The performance is average and cannot meet the parameter requirements of fine processing for single cutting and multiple cutting;

[0007] 3. The scalability of the system is poor, which makes it difficult to upgrade the pulse power supply. As a large electronic device, it is not advisable to have a low upgrade space;

[0008] 4. It is difficult to control the pulse width and inter-pulse width in a small range, which makes the surface of the processed workpiece rough and has obvious cutting stripes, which makes it difficult to meet the requirements of fine processing;

[0009] 5. The real-time performance of the system is poor;

[0010] 6. Weak anti-interference ability;

[0011] 7. The loss of the electrode wire is large when cutting a large area

[0012] Both of the above two power supply forms lead to low efficiency of wire cutting, poor reliability, and unstable surface quality of processed workpieces.
