Electromagnetic forging press

1、 General introduction of electromagnetic forging press Electromagnetic forging press belongs to high-energy (high-speed) forming technology. First of all, electric energy needs to be stored in high-voltage capacitor. When the high-voltage switch is closed, the capacitor can discharge the coil rapidly (US level) and generate a changing pulse magnetic field around it. When the pulse magnetic field passes through the workpiece, it will generate induction current (eddy current) in the metal workpiece, and the charged metal workpiece is in a rapidly changing magnetic field When the magnetic pressure reaches the yield strength of the material, the metal workpiece will have plastic deformation to achieve the purpose of forming metal parts. Electromagnetic forming technology has the characteristics of easy and accurate control of processing energy, fast forming speed, high precision of forming workpiece, small elasticity of parts after forming, improvement of plastic deformation ability of materials, simple mold and strong universality of equipment, easy to adopt composite process and realize automatic production, green and environmental protection in the whole forming process, which has been widely used in aviation, aerospace, weapon industry Automobile manufacturing, light chemical industry, instruments and electronics and many other fields. Detailed technical indicators: * PLC computer control, constant current charging; * two models of single output (P1S) or double output (P2S) are available; * dual display of magnetizing voltage digital and pointer meter; adjustable between 50V and 4000V (65 series 6500v); * the electric capacity can be switched, and the capacity is displayed; * magnetization output counting function; * output pulse current display function * multiple safety protection functions. * demagnetization function can be added additionally (/ T); 2、 Emd-60 system composition of electromagnetic forging press 2.1 control cabinet The control cabinet includes cabinet, operation panel, charge and discharge control circuit, etc. The energy storage capacitor cabinet mainly includes pulse capacitors, transformers and vacuum switches. It is equipped with power switch, pause, charge, discharge, reset button and working voltage setting knob. It is equipped with voltmeter and various indicator lights to display the working state information transmission and display methods of the equipment, including instrument display, acoustic information transmission, tactile information transmission, symbol transmission, etc. Control technology, including machine control device, instrument control device, keyboard technology, etc. Safety assurance technology, including machine safety device, human error prevention, accident control method, rescue method, safety measures, etc. 2.2 energy storage capacitor cabinet The charging circuit is an important part of the electromagnetic intensifier. It must charge the energy storage capacitor reliably and efficiently. The charging circuit includes the first level DC power supply, the second level switch charging power supply, step-up transformer, rectifier circuit and corresponding protection circuit. The function of the charging circuit is to transform the alternating current into the energy in the energy storage capacitor after boosting and rectifying. This circuit consists of the first stage DC power supply, the second stage half bridge inverter circuit, the high voltage step-up transformer, the high voltage and high current rectifier silicon pile, the current limiting resistor, the energy storage capacitor and the sampling resistor. The working process of the charging circuit is the incoming AC, through the rectifier bridge and filter capacitor, the left and right DC voltage is obtained. This voltage is the input of the second half bridge inverter circuit, the second inverter circuit is the input voltage pulse of the transformer, the high-voltage transformer raises the electric voltage to the charging voltage, after the rectification, the capacitor is charged through the current limiting resistor. The sampling voltage on the sampling resistor is sent to the comparison circuit board for comparison with the set reference voltage, and the charging stops when the preset charging voltage is reached. Display and setting: The output voltage value is adjusted by the multi turn precision potentiometer, and the working voltage and current value are displayed by the digital display meter. The fault indication is indicated by the fault indicator light. Connector: The output high voltage is connected by high voltage connector, which is safe and reliable. Main features of energy storage capacitor: ·Low power consumption, suitable for high power, high current, high voltage, high surge applications; ·With the best capacity and volume performance ratio; ·Small change with temperature, long service life; ·The peak reverse voltage is the highest; ·High energy storage, high pulse current resistance; ·Good self recovery and stable performance; ·Low inductance, low ESR; ·The shell material is stainless steel or cold-rolled plate, which is easy to install.
