Mechatronics numerical control machine tool

Abstract

The invention relates to the technical field of machine tool equipment, and discloses a mechatronics numerical control machine tool. The mechatronics numerical control machine tool comprises a machine base, a wire walking slide carriage is fixedly installed on one side of the upper surface of the machine base, a wire storage barrel is fixedly installed on the upper surface of the wire walking slide carriage, and molybdenum wires are sequentially and movably wound around the outer portion of the wire storage barrel. A workpiece slide carriage is fixedly mounted on the other side of the upper surface of the machine base. According to the mechatronics numerical control machine tool, after the molybdenum wires are thinned, the corresponding angle between two rotating plates is decreased along with the deformation amount of the molybdenum wires, so that a moving head and a conductive block move forwards by a certain distance, equivalent compensation is given when the molybdenum wires are heated to deform and the diameter is decreased, the clearance change error between the molybdenum wires and a workpiece machining surface is still reduced, and the workpiece section machining flatness is improved; and meanwhile, after the molybdenum wires are thinned and the moving head moves, a shunt circuit is connected, so that the current flowing through the molybdenum wires is reduced, the temperature rising speed around the molybdenum wires is reduced, and the service life of the molybdenum wires is prolonged.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to a mechatronic numerical control machine tool. Background technique [0002] With the increasing popularity of factory automation, mechatronic CNC machine tools have become an important part of factories in various manufacturing industries. Among them, for complex structures and special processes, there are EDM machine tools in CNC machine tools. The upper and lower poles of the workpiece are fed with pulse current, and electric sparks are generated due to the discharge effect between the electrodes, so that the metal is corroded at high temperature, and the workpiece is processed. [0003] First of all, during the process of processing the workpiece, the molybdenum wire between the two poles will generate high temperature in the cutting workpiece after being energized, and when the molybdenum wire reaches a certain temperature, the molybdenum wire passing through t...

Problems solved by technology

[0003] First of all, during the process of processing the workpiece, the molybdenum wire between the two poles will generate high temperature in the cutting workpiece after being energized, and when the molybdenum wire reaches a certain temperature, the molybdenum wire passing through the workpiece will undergo elastic deformation and under the action of the wire storage cylinder, When the diameter becomes thinner, when the molybdenum wire passes through the workpiece, the position of the molybdenum wire relative to the processed surface will shift, and then the processed surface will gradually become rough; at the same time, after the power is turned on, the temperature in the workpiece will accumulate and rise continuously, making the temperature exceed the molybdenum The melting point of the wire is too high, which in turn causes the molybdenum wire to become thinner and fuse

[0004] Secondly, due to the thinning of the molybdenum wire at the workpiece, when the molybdenum wire is thinned and rotated to the lower electrode contact plate, there will be a gap and intermittent contact with the lower electrode, and then there will be an electric corrosion discharge between the electrode contact plate, which is easy Cause electrode contact plate to burn out
