The specific embodiment
Aperture plate as shown in Figure 2 has a plurality of stratum reticulares, and is apparent, is impossible with present processing method processing.At first its number of plies is many, is five layers, and the aspect that require to cooperate so is also many, the more important thing is the muscle number of every layer of grid, and angle is all different, and cutting a cutter with line is the slit of cutting error bit angle not, therefore, must seek its method in addition.
A kind of processing method to grid of the present invention, it is to adopt the layering processing method to the processing of aperture plate, to the aperture plate among Fig. 2, processes five kinds of electrodes respectively, the outwards processing successively from the lining with five layers.This method has also been brought a series of problems such as the processing of changing electrode, electrode, the centering that is installed, concentricity.
In order to solve a series of problems such as the processing of changing electrode, electrode, the centering that is installed, concentricity, minimizing even nobody are the error that is installed and brings in the overall process of processing aperture plate, require each step of machined electrode all to realize whole numerically controlled automatics, when each operation transfer is installed, must concentric, same axiation.
The present invention has adopted several Digit Control Machine Tools substep electrode that is installed successively, with a common base, has realized benchmark bottom surface integration of operation of a plurality of operations, and the electrode of each layer can at will change like this, again can recombinant.The platform number of Digit Control Machine Tool is identical with the stratum reticulare number of aperture plate, and aperture plate as shown in Figure 2 has five layers.
Electrode of the present invention basis connector is made of benchmark bottom surface 1 an affixed clamping electrode assemblie 2 as shown in Figure 4, and clamping electrode assemblie 2 is fixed on the side of benchmark bottom surface 1.Electrode basis connector promptly constitutes a common base, with numerically controlled lathe, plain-milling machine, wire cutting machine tool and NC dividing head wildcard all.
Embodiment:
Equipment and jig that the present invention uses comprise: the very wire cutting machine tool of numerically controlled lathe, plain-milling machine, a large amount of Electronics Co., Ltd.s in Shanghai is breathed out by Japanese Sha Dike AQ35LR electric discharge machine, the U.S.; And the built-up jig and the NC dividing head of Switzerland 3R company.
The present invention is as follows to the gate electrode work flow:
The first step is finished the initial manufacture of electrode on the numerical control turning machine.As shown in Figure 5, on main shaft of numerical control machine tool 3, install benchmark bottom surface 1, electrode blank is assembled together by clamping electrode assemblie 2 and benchmark bottom surface 1, finishes the work of turning by drawing by Digit Control Machine Tool, and the scope of processing is the diameter of electrode, internal diameter and sphere.
Second step, finish the preparatory processing of electrode after, the electrode of the electrode that is installed basis connector integral body is moved on the wire cutting machine.
The 3rd step, the processing of on wire cutting machine, slotting.As shown in Figure 6, on the NC dividing head 4 of numerically controlled wire cutting machine, install benchmark bottom surface 1 equally, with car in the first step good with clamping electrode assemblie 2 be the electrode of one, be installed in again with the affixed benchmark bottom surface 1 of numerical control indexing head for linear cutting 4 on, process the seam that has different angles by drawing by wire cutting machine, finish the making of one deck electrode.Certainly, the angle of at this moment every circle seam can require arbitrarily to change according to drawing.
If any multi-layered electrode, the outwards processing successively from the lining after the center ground floor processes, repeats first to the 3rd step processing second layer electrode, and then repeats first to the 3rd step processing triple electrode or the like, is recycled to till the required number of plies.
In the 4th step, it is the electrode of 0.8mm that the requirement of grid is had one group of minimum aperture, and same location way in going on foot with the first, the 3rd installs on digital-control boring-milling machine with clamping electrode assemblie 2 and is the electrode of one, is got the aperture of minimum electrode by digital-control boring-milling machine.
In the 5th step, at the aperture that the grid center is had a 0.6mm, the electrode of this aperture goes out qualified electrode with the machine tool chief axis spin finishing, and to guarantee the vertical precision of electrode, the diameter of this electrode is about 0.5mm.
In the 6th step, the five groups of electrodes of integral body that have electrode basis connector with processing are contained on the multidigit tool magazine 8 of electric discharge machine, as shown in Figure 7 by processing sequence respectively.
In the 7th step, with about diameter 4mm, the molybdenum sheet of thickness 0.08mm clips with built-up jig 7 and to tighten up, and the position of correction and electric discharge machine main shaft 6, as shown in Figure 7.
The 8th step, last, on the molybdenum sheet base of surface one-tenth sphere, process aperture plate by electric discharge machine.The processing of aperture plate begins in layer to process from inside to outside from aperture, and after first electrode processed, the lathe follow procedure was placed on the room with electrode automatically, remove to take second electrode again, follow procedure is gone to the position of processing, and the rest may be inferred, and repetitive positioning accuracy is at 0.005mm.
Electrical quantity also is very important in the process of processing aperture plate, but because of the lathe difference, condition is discrepant, has not just here introduced.
