Description
Technical field
The invention belongs to the auxiliary facility field of wire-cut electric discharge machine, be specifically related to a kind of working fluid supply system.
Background technology
With the working fluid supply system of water as the wire-cut electric discharge machine of working fluid, comprise spraying water kenel method of supplying or with the method for supplying of kenel of soaking, the temperature that the working fluid supplied can be used for cooling the generation of electric discharge machining process heat raises, and then makes the working fluid temperature remained constant in process; The working fluid that separately can flow is taken away electric discharge and is added man-hour, the chip residue that workpiece to be machined produces.
In the bench structure of each known wire-cut electric discharge machine, comprise the table unit of one group of multiaxis, the control unit of a controller electronic box, the supply system unit of a working fluid.And this working fluid supply system, then there is a sewage memory space respectively for storage sewage, a water purification memory space for storage water purification, a submerged motor will add water purification needed for man-hour by the processing tank of Pipeline transport to wire cutting machine, after the chip residue of commingle discharging generation in process becomes sewage, sewage memory space is put into again by tubes rows, become water purification after sewage being extracted into filtration devices by pumping, return water purification memory space, form a circulation.For guaranteeing that wire cutting machine is in the water purification amount added needed for process water groove in man-hour of discharging, water purification memory space adds the water capacity of sewage memory space, mostly be designed to more than 2.5 times that process tank water capacity, to avoid the moisture storage capacity because of memory space not enough, pumping occur and takes out the situation of burning less than water.Such as, the wire-cut electric discharge machine commonly used as shown in Figure 1 comprises in the schematic diagram of machine table and water treatment facilities, and the sewage after process is entered sump 2 via a pipeline 12 by a processing tank 1; One pumping 8 by the road suction eye 9 is extracted into Rose Box 5 by containing the sewage of chip residue, and sewage becomes water purification after completing filtration, then enters in clear water tanks 3 and store; Add man-hour carrying out electric discharge, then by a submerged motor 6, water purification is conveyed into processing tank 1 through water pipe 7, so forms a circulation.This known water treatment mode is when avoiding the sewage quantity of sump 2 in cyclic process not enough, generation pumping 8 is taken out and is burnt less than water, so design sump 2 adds that the water capacity of clean water tank 3 must be greater than more than 2.5 times of processing tank water capacity, causing the volume of water treatment facilities relatively to increase increases with floor space.So the occupation of land space of known wire-cut electric discharge machine increases all relatively, so can reduce the volume utilization rate using wire cutting machine work area, the manufacturing cost of user increases.
So improve the design of wire cutting machine water system in located by prior art, for the purpose of the demand reducing water tank floor space or water tank capacity.Such as No. TWM386127U1st, Taiwan new patent, shown in Fig. 2, an one-way guide flow device 11 is installed between foul water tank 2 and clear water tanks 3, the conduction pipe 10 of this one-way guide flow device 11 runs through the dividing plate 4 between sump 2 and clean water tank 3, utilize the change of sewage hydraulic pressure in water purification hydraulic pressure in clean water tank 3 and sump 2, this one-way guide flow device 11 is made to do unidirectional switch motion, unidirectional being back in sump 2 can mix with sewage with the water purification controlled in only clean water tank 3, do the adjustment of sewage quantity in case pumping 8 is burnt.So can avoid because water purification in processing is by quick suction processing tank, sewage is also relatively drawn into filtration system and is filtered when replenishing water purification memory space again, and the water shortage because of sewage memory space causes anhydrous taking out, and makes the situation that motor burns out.Design sump 2 so adds that the water capacity of clean water tank 3 can be improved as 1.8 times of processing tank water capacity.
