An overflow device is arranged on the processing slot noumenon, and the upper overflow mouth of the overflow device is higher than the bottom of the processed workpiece in the processing slot. Since the overflow device is arranged in the slot, the bottom of the processed workpiece is provided with working liquid, and the top-and-bottom consistency of the hole diameter of a processing hole on the processed workpiece is ensured.
Description
Technical field
The utility model relates to a kind of high speed aperture electric discharge device.
Background technology
Prior art, shown in accompanying drawing 3-accompanying drawing 5, the working groove of high speed aperture electric discharge device comprises working groove body 1, is arranged on the fluid hole 7 on the described working groove body 1 shown in accompanying drawing 4 and accompanying drawing 5.In high speed aperture electric discharge device, for normally carrying out of guaranteeing to process, need working solution (for example pure water or saponification liquor etc.) as discharge medium, as shown in Figure 3, by swivel head 11 clamping electrode pipes 12 and drive its rotation, working solution 15 enters from hollow electrode tube 12, when perforation processing is discharged to workpiece 13 in the bottom of electrode tube 12, working solution plays three kinds of effects: the firstth, discharge the impurity that discharge processing back produces, working solution 15 is 16 discharges from the gap between electrode tube 12 and the workpiece 13, and the impurity of processing is also discharged from the side clearance 16 of electrode tube 12; The secondth, play the effect of the discharge medium between electrode tube 12 and the workpiece 13; The 3rd is to play the effect that the heat after the discharge is dispelled the heat, and guarantees normally carrying out of processing.
The problem that exists is at present, when in its bottom of workpiece to be machined 13 processed punctures, working solution flows out from the hole that workpiece 13 bottoms are got through earlier, duty when causing electrode tube 12 to be worked into workpiece 13 bottommosts is different with this duty before, makes between electrode tube 12 and the workpiece 13 and can not carry out electric machining well.There is error in the bottom part aperture diameter of evidence workpiece 13 after machining, and the size in the hole of workpiece 13 bottommosts is less than normal, and has tangible inconsistency with top aperture.Therefore, illustrate that this kind processing method and device can influence the aperture uniformity of processed workpiece 13.Its reason is because electrode tube 12 when workpiece 13 parts are punched, working solution flows out from the hole that the bottom of workpiece 13 is punched, gap 16 between feasible electrode tube 12 at this moment and the workpiece to be machined 13 does not have or has only a spot of working solution to serve as medium, causes the discharge between electrode tube and the workpiece to be machined 13 undesired; Residue is got rid of not smooth from gap 16, also can cause short circuit between electrode tube 12 and the workpiece 13, and cause electrode tube to move up automatically; The undesired electrode tube 12 that also can make of discharge between electrode tube 12 and the work piece 13 is shaken, and reduces process velocity.
Summary of the invention
The utility model purpose provides a kind of working groove of high speed aperture electric discharge device, should be able to guarantee the property unanimous between the higher and lower levels in the machining hole aperture on the workpiece to be machined when the electrode tube processing work.
For achieving the above object, the technical solution adopted in the utility model is: a kind of working groove of high speed aperture electric discharge device, comprise the working groove body, be arranged on the fluid hole on the described working groove body, described working groove body is provided with overflow mechanism, and the overfall on this overflow mechanism is higher than the workpiece bottom of the work piece in the working groove.
Because technique scheme utilization, the utility model compared with prior art has following advantage: a kind of working groove of high speed aperture electric discharge device, owing in groove, be provided with overflow mechanism, make and when the processing work bottom, still have working solution, working solution to help discharging the impurity that discharge processing back produces; Working solution serves as medium, makes that the discharge processing between electrode tube and the workpiece to be machined is normal; Working solution can dispel the heat to the heat of the generation after the discharge processing, thereby has guaranteed the property unanimous between the higher and lower levels in machining hole aperture on the workpiece to be machined.

The specific embodiment
Shown in accompanying drawing 1-accompanying drawing 2, a kind of working groove of high speed aperture electric discharge device, comprise working groove body 1, be arranged on the fluid hole 7 on the described working groove body 1, described working groove body 1 is provided with overflow mechanism 9, this overflow mechanism 9 is provided with overfall 6, described overfall 6 is higher than the bottom that is arranged on the workpiece to be machined in the described working groove body 1, described overflow mechanism 9 can be working groove body 1, the opening of described overfall 6 can be set directly on the working groove body 1, also be provided with feeding device 8 on the described working groove body 1, this feeding device 8 is provided with feed liquor valve 2, in described working groove body 1, also be provided with pumping equipment 10, be provided with tapping valve 4 on described pumping equipment 10, the outlet of this tapping valve 5 is connected with the fluid hole 7 that is arranged on described working groove body 1.
Shown in accompanying drawing 1 and accompanying drawing 3, before beginning processing, working solution 15 enters in the working groove body 1 from inlet 3, when the liquid level position of working solution arrives overflow position, feed liquor valve 2 cuts out, make the bottom of working solution submergence workpiece to be machined 13, and liquid level remains at this position when electrode tube 12 processing works 13.Add man-hour, as shown in Figure 3, swivel head 11 clamping electrode pipes 12 also drive its rotation, working solution 15 enters from hollow electrode tube 12, in the bottom of electrode tube 12 workpiece 13 is formed discharge and add man-hour, the existence of working solution 15 can be played three kinds of effects: the firstth, and the impurity that discharge discharge processing back produces, working solution 15 is 16 discharges from the gap between electrode tube 12 and the workpiece 13, and the impurity of processing is also discharged from the side clearance 16 of electrode tube 12; The secondth, play the effect of the discharge medium between electrode tube 12 and the workpiece 13; The 3rd is to play the effect that the heat after the discharge is dispelled the heat, and guarantees normally carrying out of processing.When 12 pairs of workpiece 13 of electrode tube are worked into its bottom, because working solution is the bottom of submergence workpiece to be machined 13 all the time, promptly this moment, workpiece 13 bottoms still had working solution 15, thereby the discharge that does not influence its normal despumation, 12 pairs of workpiece 13 of electrode tube is processed and heat radiation, make that the property unanimous between the higher and lower levels in machining hole aperture is guaranteed on the workpiece to be machined 13, simultaneously, process velocity has also obtained certain raising.After machining, can open tapping valve handle 4, working solution 15 is discharged by fluid hole 7 through tapping valve 5.
