The pulse generator PG-M1
The pulse generator PG-M1 is designed to equip electrical discharge copying broaching machines.The structure of PG-M1 includes a specialized power module, which provides formation oxide breackdown pulses on the surface of workpieces made of titanium alloys.
Part number:
Description
Advantages:
- prompt assignment of different rise time and fall time working pulses which leads to optimization for processing parameters, such as the performance and deterioration of the electrode-tool (ET),
- prompt assignment of four forms of working pulses - rectangular, trapezoidal, exponential and with sinusoidally rising edge. Each pulse is distributed to 32 segments. There is a possibility of inclusion of an additional pulse within each pulse, which will have demanded amplitude and duration synchronized with the falling edge of the working pulse,
- smooth change, within wide limits, of size of an interelectrode gap (IEG) and system reaction speed on IEG condition during production,
- protection against arcing and short circuit in IEG (with the possibility of changing the threshold level), allowing to prevent occurrence of mentioned adverse effects before their development,
- ET motion and supply control, provided with use of drive by stepping motor, and ball-screw gear,
- compactness.
Main functionality:
1. Ensuring compliance of the technological process for a given program.
2. Control and management of the electrode-tool for a given program in a feedback mode.
3. Formation of the five types of current pulses: ignition, working, protective, for processing titanium alloys, the current additions with the possibility of adding synchronization pulses to their reciprocal packet from the front.
4. Input parameters of the technological process from the ESA machine or from any PC.
5. Pairing with a device digital display of linear displacement transducer.
6. Maintaining voltage setpoint of electrode gap in the range of 30 - 50 V by moving the drive control electrode tool on «W» axis.
7. Working out detail's mode of contact.
8. Determination and development of a condition of short circuit in an operating mode.
9. Parameters storage for settings of pulse forming for multiple processing frames.
