Abstract
The utility model discloses an electrode used for EDM (electric discharge machining) of deep hole. The electrode comprises a front end and a rear end and has the improvements that two spiral grooves are arranged on a cylindrical surface of the electrode, and an oil hole is arranged at the axial center position of the electrode; and the front end of the electrode is conical, and meshy holes are arranged on a cone at the front end of the electrode and are communicated with the oil hole. In the electrode used for EDM of deep hole, as the spiral grooves are arranged on the cylindrical surface of the electrode, in the machining process of the deep hole, carbon residues generated by electric discharge can be conveniently removed out of the deep hole, so that the carbon accumulating phenomenon in the machining process is fundamentally avoided, the machining redundancy is eliminated, the machining speed is increased, and the machining precision is ensured.
Description
[technical field]
The utility model relates to the electrode structure that uses on the spark machined machinery, the electrode structure that particularly a kind of electric spark deep hole machining is used.
[background technology]
At present; Some plastic moulds are after the die trial first time, for the quality of improving shaped article need be made amendment to the cooling system (being commonly called as fortune water) of mould, if mould hardness is more than HRC50 ° (die); Traditional drilling mode has just been processed not this fortune water hole; Generally will adopt the spark discharge method for processing, the electric spark deep hole machining adopts the spark discharge operation principle, by act on the pulse power between electrode and the workpiece discharge lose except that workpiece to reach the pass of required processing; Pass to high-pressure work liquid in the middle of the electrode, play chip removal and cooling effect.There are some problems in traditional spark machined, and for example when the fortune water hole of diameter 10mm, working depth reaches 40mm when above; Will produce carbon distribution, cause processing redundant, and the degree of depth in general fortune water hole all surpass 80mm; Will greatly waste process time like this, but also can not guarantee machining accuracy, even possibly cause workpiece to scrap; For this reason; Study the electrode that a kind of spark machined is used, can fundamentally improve the carbon distribution phenomenon in the process, eliminating the processing redundancy is a problem demanding prompt solution.
[utility model content]
The utility model aims to provide the electrode that a kind of electric spark deep hole machining that can effectively overcome the problems referred to above generation is used to deficiency of the prior art, and it can improve the carbon distribution phenomenon in the deep hole machining process, has improved working (machining) efficiency and machining accuracy.
The purpose of the utility model is achieved in that it comprises electrode front end and rear end, and its improvement is: said electrode offers helicla flute on the face of cylinder, and the electrode shaft core position has oil through;
In the said structure, said helicla flute is two;
In the said structure, said electrode front end is coniform;
In the said structure, said electrode front end circular cone is provided with reticulated cell, and reticulated cell communicates with oil through;
In the said structure, leave certain distance between said oil through and electrode front end circular cone bottom surface;
In the said structure, leave the distance of 3-5mm between said helicla flute and electrode front end circular cone bottom surface.
The utility model electric spark deep hole machining is used electrode, on the face of cylinder of electrode, has helicla flute, and the electrode shaft core position is provided with oil through; In the process of deep hole machining, before electric discharge machine discharged each time, spark oil just poured deep hole from oil through; During electric discharge machine feeding discharge; The spark oil just helicla flute from the face of cylinder is discharged deep hole, also discharges deep hole (chamber deeply) to the carbon slag of discharge generation simultaneously, has fundamentally improved the carbon distribution phenomenon in the process; It is redundant to eliminate processing, has improved process velocity and has guaranteed machining accuracy.
