specific Embodiment approach 1
[0082] Specific implementation mode 1. Refer to Figures 1 to 10 Embodiments will be described. A multi-mode adjustment method based on a multi-mode adaptive pulse power supply described in this embodiment, the multi-mode adjustment method is realized based on a multi-mode adaptive pulse power supply for EDM of multi-layer materials,
[0083] Multi-mode adaptive pulse power supply for EDM of multi-layer materials, which includes industrial computer, discharge gap, drive amplifier module 1, discharge main circuit 2, sampling module 3, main controller 4, voltage divider chopping sampling circuit and eddy current sensor ;
[0084] The drive amplification module 1 includes 8 low-voltage loop drive circuits 1-1, 1 high-voltage loop drive circuit 1-2, and 1 negative pulse loop drive circuit 1-3; low-voltage loop drive circuit 1-1, high-voltage loop drive circuit 1- 2 and the negative pulse loop drive circuit 1-3 are independently powered by DC power supply, and do not share a comm...
specific Embodiment approach 2
[0144] Specific implementation mode two, refer to Figure 4 Note that in this embodiment, the main controller 4 in step three performs mode selection processing according to the discharge parameter serial data, discharge time sampling signal, abnormal discharge sampling signal, and material type sampling signal. The mode selection processing method is as follows :
[0145] The serial port receiving module 4-1 receives the discharge parameter serial data required by the multi-layer material EDM sent by the industrial computer, converts it into discharge parameter parallel data according to the corresponding logical structure and sends it to the parameter adjustment module 4-3;
[0146]The material type discrimination module 4-2 receives the material type sampling signal sent by the material type sampling circuit 3-3 and the low-voltage loop PWM signal output by the PWM generation module 4-5, and performs a detection of the material type according to the material type sampling s...
specific Embodiment approach 3
[0154] Specific implementation mode three, refer to Figure 8 Describe this embodiment, described mode selection module 4-4 carries out mode selection according to pulse mode signal, and outputs high-voltage pulse signal, negative pulse signal and 5 road mode enabling signals to PWM generation module 4-5; Said 5 road mode The enable signals are enable signal 1, enable signal 2, enable signal 3, enable signal 4 and enable signal 5, which are used to control the work and stop of the PWM generation module 4-5, wherein the mode selection mode is as follows:
[0155] Pulse mode signal input, after the input, it is divided into two ways, one way judges the last 3 digits of the pulse mode signal, and the other way outputs the first 5 digits of the pulse mode signal;
[0156] When judging the last 3 bits of data in the pulse mode signal, if it is "001", the equal voltage enable output is '1', other modes enable output '0', and the other mode enable output '0' is returned for continued...
