Description
Technical field
The present invention relates to a kind of high-voltage spark line processing unit (plant) and processing method, relate in particular to a kind of high-voltage spark line processing unit (plant) of realizing the workpiece rotation by rotary table, also relate to simultaneously and utilize this device to realize the polishing method for processing, belong to the EDM Technology field.
Background technology
In recent years, along with the fast development of IC industry, the demand of various diamond micropore molds is presented the trend that increases day by day.But, the difficulty of processing of diamond micropore mold is very big, for example the endoporus pass of diamond micropore mold is that 6 zones such as sizing of 0 ° are formed by the outlet with different angles, back taper, compression, lubricated, inlet and angle, and the micropore mold aperture of minimum has only 0.005mm.For the micropore mold of aperture, pre-hole less than 0.003mm, process with conventional processing method such as Ultrasonic machining, line polishing processing etc., all need to use the instrument more very thin than the endoporus of diamond micropore mold, implement difficulty and very greatly almost can't finish.
In number of patent application is 200810030300.9 Chinese invention patent application, a kind of finishing method of diamond rectangle micropore mold die hole is disclosed, it is conceived substantially: with mould holder in the anchor clamps that are complementary with mould, the locality of mould in anchor clamps is adjustable, the polishing arrowband pump to die orifice wherein one group of opposite side polish mould half-twist then, another group opposite side of polishing arrowband polishing nib one by one, by that analogy, but whole periphery in the polished bore.This finishing method can polish rectangular micropore, all can play ablation to the long limit and the broadside of rectangle nib, and the shape that helps the hole keeps; The polishing arrowband can not be twisted fracture, the polishing efficiency height in polishing process.
Zhang Qinjian, Cao Fengguo etc. point out that in " research of artificial single crystal's diamond laser micropore process technology " (being stated from " diamond and grinding materials and grinding tool engineering " the 2nd phase in 2009) the traditional laser boring method of artificial single crystal's diamond adopts " consistency profiles ".The shortcoming of this method is that the material of peelling off the closer to the center in hole is many more, and accurate pass is difficult to obtain.This paper has proposed a kind of new laser numerical control punching adaptive model on the basis of theory and practice.In the compressional zone of mould, realize the even removal of material by the rotating speed of control workpiece, and pulsed laser energy is successively decreased along with reducing of aperture, to improve the pass precision.
On the other hand, electric processing methods such as electron beam processing, ion beam processing and Laser Processing successively appearred after the 1950's.These electric processing methods are without the instrument of moulding, but utilize the very high energy beam stream of density to process, and are particularly suitable for processing the peculiar part of high hardness material and complicated shape, precise fine.

Fig. 8 is the structural representation of the insulating coating of clamping workpiece to be processed.Workpiece to be processed is installed in the center of insulating coating 14.Adding man-hour, will be that the workpiece to be processed of material is installed among the insulating coating 14 that insulating materials such as plastics or pottery make with rough diamond or artificial single crystal's diamond etc. at first, and clamping be on rotary table 1.When the clamping workpiece to be processed, should guarantee that the endoporus center of workpiece to be processed overlaps with the center of insulating coating 14, the center of insulating coating 14 also overlaps with the pivot of rotary table 1 simultaneously, to guarantee the hole shape quality.Under the drive of electric rotating machine 3, rotate on the pivot of rotary table 1 at the endoporus center of workpiece to be processed, pass workpiece to be processed by the high-voltage spark line, the workpiece endoporus in the rotation is carried out polishing processing, can significantly improve the hole shape circularity of workpiece to be processed.
Below, realize that to utilizing high-voltage spark line processing unit (plant) shown in Figure 4 the concrete grammar of polishing processing is described in detail.At first, the different requirements according to the different Working positions of diamond micropore mold endoporus to be processed utilize high-voltage spark beam position guiding mechanism to carry out position adjustments, make workpiece to be processed just in time be arranged in the tail end and the segment limit of high-voltage spark line.Then, requirement according to diamond micropore mold hole shape zones of different to be processed, further utilize high-voltage spark line angle-adjusting mechanism to adjust, the requirement of adjustment is to make to form 0 ° to 5 ° angle between the central axis of high-voltage spark line and rotary table 1.
Particularly, earlier the angle position of adjustable electrode angle board 9 is transferred to maximum, insulating coating 14 as shown in Figure 8 is installed on rotary table 1, again adjustable electrode angle board 9 is transferred to the normal position and is begun processing in first being processed.In process, rotary table 1 remains rotation, and the energy basic fixed of high-voltage spark line, utilizes the tail end of high-voltage spark line to carry out shaping processing.In this process, can adjust the relative position of high-voltage spark line and workpiece to be processed as required.After the hole shape circularity for the treatment of the workpiece sizing area reaches requirement, it is motionless that the high-voltage spark beam position keeps, further adjust the angle of adjustable electrode angle board 9, the axis shape of high-voltage spark line and workbench pivot is had a certain degree, help the slick and sly smooth of each regional perspective of workpiece endoporus like this.In the actual processing, guaranteeing that this angle is the bigger the better under the normal situation of high-voltage spark line, but generally should not surpass 5 °, otherwise can influence normally carrying out of processing.This fine setting angle is carried out high-voltage spark line method for processing, is the effective measures that guarantee workpiece to be processed endoporus hole shape smoothness.
In addition, add man-hour in the shaping that focuses on the diamond micropore mold, it is higher to utilize the tail end of high-voltage spark line to carry out working (machining) efficiency.Improve in the processing of diamond micropore mold fineness at needs, integrated operation and above-mentioned shaping processing are similar, different is the position of wanting mobile high-voltage electric spark line, the high-voltage spark line is moved to workpiece account for 1/3 place of line total length, the processing that utilizes the stage casing of high-voltage spark line workpiece to be improved fineness apart from tail end.The effect that facts have proved such processing is best.
Utilize processing unit (plant) provided by the present invention and processing method that the diamond micropore mold is carried out polishing processing, its hole shape and fineness can both be guaranteed, and crudy significantly improves.On the other hand, in process, only need measure the mould aperture, and needn't frequently control processing according to the output energy of hole shape quality adjustment high-voltage spark line generator, and close the unproductive time that start observation adjustment is caused thereby reduced significantly, improved production efficiency.
More than the high-voltage spark line processing unit (plant) and the processing method of workpiece provided by the present invention rotation had been described in detail.To those skilled in the art, any conspicuous change of under the prerequisite that does not deviate from connotation of the present invention it being done all will constitute to infringement of patent right of the present invention, with corresponding legal responsibilities.
