Embodiment Construction

[0015] see figure 1 , Divide the inverter into three independent parts: power module, 2, control module 3, and frequency conversion module 4. The control module 3 is externally connected to the input signal through the connector DB15 and DB25 socket, and the frequency conversion output is connected to the wire conveying, the water pump motor and the lighting lamp through the 12-core aviation socket.

[0016] see figure 2 , In the power supply module, LED displays are added corresponding to each power supply to indicate the working status of each power supply. figure 2 The schematic diagrams of adding LEDs to the bus voltage of the frequency conversion module, the working voltage of the frequency conversion module, the working voltage of the control module and the control loop voltage of the control module are respectively shown. see image 3 , LED lights are connected in series in each control loop to monitor the operation of each control point in real time. Therefore, n...

Abstract

The invention discloses a special frequency converter for an electric discharge machining linear cutting machine, wherein the main body of the electric discharge machining linear cutting machine is a 750/1500W three-phase motor driven by 220V alternating current in a variable frequency driving mode, and belongs to the field of electrical industry. The frequency converter used for the electric discharge machining linear cutting machine is composed of three independent portions which are a power supply module, a controlling module, a frequency conversion module, and all the modules are distributed in a 300*200*80 mm small case. The controlling module is connected with an external input signal through a connector DB15 and a socket DB25, and a frequency conversion output is connected with a transport wire, a water pump motor and an illuminating lamp through an aeration socket with twelve cores. The frequency converter used for the electric discharge machining linear cutting machine is simple in structure, convenient to maintain, and simple to install.

Description

technical field [0001] The invention is a dedicated frequency converter for electric spark wire cutting machine tools, which belongs to the field of electronic industry. It is an upgraded product of electrical discharge wire cutting machine tool. Background technique [0002] The frequency converter has a wide range of applications and complex technology, involving three important factors: strong, weak and high frequency. Since the various performances of the frequency converter are concentrated on one circuit board, mutual interference will lead to extremely unstable performance and increase the difficulty of maintenance personnel, so there is currently no frequency converter specially used in wire electric discharge machine tools . Various manufacturers prefer to choose very cumbersome old machine tool electrical appliances instead of convenient and fast frequency converters. Contents of the invention [0003] This frequency converter is an improvement and reasonable ...
