Description

For separating and recovering the filter and separation and recovery of the cutting fluid of rare metal wire cutting System

Technical field

The utility model belongs to rare metal electric spark machining field, in particular to a kind of for separating and recovering rare metal The filter and separation and recovery system of the cutting fluid of wire cutting.

Background technique

Rare metal tungsten belongs to rare metal granite, has the characteristics that fusing point is high, density is big, hardness is high, expensive. The processing of rare metal components is generally using machining and electrical discharge machining.Due to machining generate metal debris compared with More, waste is larger, so, electrical discharge machining is more favored, and is that tungsten part processes most-often used means.Spark cutting Processing is also known as wire cutting, and the galvano-cautery phenomenon that principle generates when being using two interpolar pulsed discharges carries out cutting to material and adds The method of work.The advantages of wire cutting, is: 1) " can defeat a force with a tenderness ", particularly suitable in the very high rare gold of the such hardness of tungsten Belong to material；2) machining accuracy is high, and saves raw material, since cutting uses very thin molybdenum filament etc., so that the gap after cutting is non- It is often small, it can significantly avoid wasting；3) intelligentized control method may be implemented in high degree of automation.Just because of this of wire cutting A little features, so that the processing method is widely applied in tungsten part manufacturing, linear cutter becomes current tungsten Essential process in part processing.

The value of rare metal is higher, such as tungsten and molybdenum material, and about 300-600 member/kg, therefore, the scrap of tungsten is necessary It recycles and reuses.But be different from standard machinery and process, the scrap generated after wire cutting is very tiny, so that becoming Pureed, the extremely difficult separation of cutting fluid circulation provided for oneself using equipment.The cutting fluid circulation that linear cutting equipment is provided for oneself uses Filter element filtering has the drawback that

1) since scrap is tiny, filter core is frequently occluded, and general single device just needs replacing a filter core, filter core in every 10 days Price is about 300 yuan/, monthly needs 900 yuan, whole year about needs 10800 yuan；

2) filter core cleaning is difficult, and cannot clean out, and wastes many metal mud, about waste 12kg is golden every year for every equipment Belong to mud, is worth about 1200 yuan；

3) cutting fluid recycled is muddy, and easily rotten, about per two weeks just needs replacing once, and more exchange treaties needs 100 every time Member, single device whole year about need 2400 yuan；

4) mixed liquor of cutting fluid and metal mud influences environmental protection, and third party can only be transferred to as dangerous waste processing.

In summary, the loss that delays work for replacing cutting fluid and filter core does not count, and annual every equipment needs are being cut The economic loss cut in terms of liquid is about 1.5 ten thousand yuan, is calculated according to 50 equipment, about loses 750,000 yuan every year.
