Description

Working liquid scrap removing device of electric spark machine tool

Technical Field

The invention relates to a working solution scrap removing device, in particular to a working solution scrap removing device of an electric spark machine tool.

Background

The electric spark machining is a common machining mode in the current industrial production, and is widely applied in the manufacturing industry, because of the discharge action between a workpiece and an electrode, the discharge position of the workpiece and the electrode is rapidly oxidized and corroded, and the discharge position is eliminated along with working fluid, in the electric spark machining process, the working fluid plays the roles of cooling, chip removal and insulation, in the machining process, scraps generated by the workpiece circulate along with the working fluid, after the scraps in the working fluid are accumulated to a certain proportion, the scraps in the working fluid can influence the discharge state of the electric spark machining, even cause the blockage of a channel, aggravate secondary discharge, and seriously influence the discharge effect and the machining surface quality, the main means for removing the scraps in the working fluid is to arrange a layer of magnetic filter screen in a working fluid box body, not only limited by the material of the machined workpiece, but also limited by the aperture size, the waste scraps in the working solution are not completely filtered, the filtering effect is not ideal, and the reuse rate of the filter screen is low.

Disclosure of Invention

The invention mainly aims to overcome the defects of the prior art, provides the working solution chip removing device suitable for the electric spark machine tool, solves the problem that the pipeline is blocked due to the fact that the concentration of the waste chips in the working solution is too high, improves the processing quality and improves the utilization rate of the working solution.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the scrap removing device is suitable for working solution of an electric spark machine tool and comprises a box body, a transmission device, an electric spark machining device, a conveying belt, an electromagnetic filter plate, a plurality of layers of filter plates and a scrap removing brush, wherein the box body is arranged at the machining position of the electric spark machine tool.

Furthermore, the transmission device is divided into a driving rotating shaft and a driven rotating shaft which are respectively arranged at corresponding positions of the box body, and a driving shaft of the transmission device is lower than a driven shaft.

Furthermore, the conveyer belt is arranged on a driving shaft and a driven shaft of the transmission device, so that the working liquid and the waste chips can be conveniently conveyed downwards.

Furthermore, the chip removing brush is arranged near the driving shaft of the transmission device, so that the brush of the chip removing brush can be effectively contacted with the surface of the conveying belt, and processing waste chips attached to the conveying belt can be conveniently removed.

Furthermore, the electromagnetic filter plate generates a stronger magnetic field near the filter screen under the power-on condition, which is beneficial to adsorbing ferromagnetic scraps in the working fluid.

Furthermore, the multilayer filter plate is used for filtering tiny non-ferromagnetic particles in the working fluid, and can realize cleaner filtering of scraps in the working fluid.

The invention has the advantages that: after the electromagnetic filter plate is used, ferromagnetic scraps in the electric spark working fluid can be filtered more effectively, the electromagnetic filter plate can be reused for many times, the multi-layer filter plate can effectively filter non-ferromagnetic scraps, the utilization rate of the working fluid is greatly improved, and the machining precision is improved.

Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings in the invention.

Referring to fig. 1, 2, 3, and 4, an embodiment of the present invention includes: in order to solve the problem of scrap in the electric spark machining liquid, the invention adopts a scheme that: an electric discharge machine tool working fluid chip removing device, comprising: 1. a box body; 2. a working outlet; 3. a plurality of layers of filter plates; 4. an electromagnetic filter plate; 5. a dandruff removing brush; 6. a transmission drive shaft; 7. a conveyor belt; 8. a transmission driven shaft; the lower ground in the box body 1 has an inclination angle of 3-5 degrees, so that the working fluid can conveniently flow to the left side of the box body 1 shown in figure 2, the installation position of the driving shaft 6 of the transmission device is lower than the driven shaft 8 of the transmission device, the conveyer belt is driven to rotate anticlockwise under the anticlockwise rotation (the rotating speed is 0.5-1m/s) of the driving shaft 6 of the transmission device, the conveyer belt 7 is positioned below the machining workbench, and the working fluid and the waste chips can be just splashed onto the conveyer belt 7 and move downwards along with the conveyer belt 7 in the electric spark machining process.

The scrap removing brush 5 is used for cleaning scraps adhered to the conveying belt, the electromagnetic filter plate 4 is arranged on the box body 1 through the upper guide rail of the box body 1, the principle is like a drawer, in a working state, the power supply of the electromagnetic filter plate 4 is turned on, the electromagnetic filter plate 4 has magnetism, ferromagnetic scraps can be adsorbed and shut, after the work is finished, when the scraps are cleaned, the electromagnetic filter plate 4 is taken down, the power supply of the electromagnetic filter plate 4 is turned off, the magnetism is weakened and is not enough to adsorb the ferromagnetic scraps, the scraps fall off, and the cleaning and the reuse are convenient.

The multi-layer filter plate 3 is composed of multi-layer filter plates and used for cleaning non-ferromagnetic scraps, is installed on the box body 1 according to the same principle as the electromagnetic filter plate 4, is taken down when the filter plates are cleaned or replaced, is convenient to operate, and through the process, filtered working fluid flows out of the working fluid outlet 2 on the box body 1 to complete the working fluid filtering process.
