Novel filter of spark-erosion wire cutting machine bed working solution case device

Technical Field

The utility model belongs to the field of electric spark wire cutting machining, and particularly relates to a novel filtering device for a working liquid tank of an electric spark wire cutting machine tool.

Background

Working liquid in a working liquid tank of a reciprocating wire-moving spark wire-cutting machine is easily polluted by scraps and oil stains, and the surface quality of a machined workpiece is affected by excessive impurities of the working liquid for spark wire-cutting machining, so that the impurities in the working liquid need to be filtered, and the cleanness degree of the working liquid is ensured.

SUMMERY OF THE UTILITY MODEL

Detailed Description

In spark-erosion wire cutting course of working, inside the working solution got into filter equipment by feed liquor pipe 2, the working solution filters most impurity through filter screen 5 under the effect of gravity to deposit partly impurity in semi-circular setting box, flow into the working solution incasement via No. two filter screens 6 and fluid-discharge tube 4 again.

The first filter screen is composed of a cross filter screen and a spiral filter screen, has a certain angle in the horizontal direction, is beneficial to filtering impurities, can be taken out from the lower part of the filter device, and is convenient to clean and maintain.

The drain pipe is in threaded fit with the shell, so that the drain pipe is convenient to disassemble, and the first filter screen can be prevented from sliding downwards when being screwed down.

The interior shape of the semicircular precipitation box is semicircular, which is beneficial to the precipitation of impurities, and the semicircular precipitation box is matched with the shell by screw threads, so that the semicircular precipitation box is convenient to disassemble and clean.
