Magnetic precipitation filtering device for electric-spark linear cutting machine tool working fluid

Abstract

The invention discloses a magnetic precipitation filtering device for an electric-spark linear cutting machine tool working fluid. The magnetic precipitation filtering device comprises two or more settling boxes, and the magnetic precipitation filtering device is characterized in that all the settling boxes are longitudinally arranged in an overlapped manner, two or more longitudinal baffle plates are fixedly arranged in each settling box, bent flow channels are formed, two or more horizontal sliding grooves are formed in the outer side of the bottom of each settling box at intervals, a permanent magnet is arranged in each horizontal sliding groove, and the tail end of the flow channel of each settling box is provided with an overflowing hole. The magnetic precipitation filtering device for the electric-spark linear cutting machine tool working fluid has the advantages that the electric-corrosion particle separating effect is good, cleaning is easy to achieve, and other effective components are not affected, and therefore performance of the working fluid is guaranteed for a long period.

Description

technical field [0001] The invention relates to a filtering device for the working fluid of electric discharge wire cutting machine tools. Background technique [0002] The main functions of the working fluid for wire-cut electric discharge machine tools are: 1. Form a discharge channel as a working medium; 2. Cool the workpiece and electrode wire; 3. Take away discharge products, reduce secondary discharge energy loss, and ensure processing stability. [0003] The discharge product: galvanic corrosion particles, needs to be separated from the working fluid in time to facilitate the recycling of the working fluid; because the galvanic corrosion particles are extremely small, with a diameter of about 0.005mm, their weight is extremely light, and it is difficult for free sedimentation to overcome the resistance of water. In case of agitation by the water flow (such as the high-speed rotation of the water pump), the eroded objects cannot settle; at present, paper core filters a...

[0003] The discharge product: galvanic corrosion particles, needs to be separated from the working fluid in time to facilitate the recycling of the working fluid; because the galvanic corrosion particles are extremely small, with a diameter of about 0.005mm, their weight is extremely light, and it is difficult for free sedimentation to overcome the resistance of water. In case of agitation by the water flow (such as the high-speed rotation of the water pump), the eroded objects cannot settle; at present, paper core filters are mostly used, but if the filtration accuracy is high, although the eroded objects are effectively filtered, the effective components of the working fluid will also be affected. Different degrees of influence, but the precision is low and it is impossible to obtain a good filtering effect, so that a large amount of electric corrosion is mixed in the working fluid, which not only changes the conditions of EDM cutting, but also irreversibly affects the performance of the working fluid. attenuation
