Description

Technical field

[0001] The present invention relates to the technical field of electrode discharge machining, in particular to a machining method of a dual-angle electrode and an electrode structure thereof. [Background Technology]

[0002] like Figure 1 The workpiece shown in the figure has two double-angle undercut holes 30. Normally, the workpiece 20 needs to be placed at two angles in sequence before discharge can be performed. However, this method is difficult to discharge and the processing accuracy is difficult to control. Alternatively, a reference can be made in the XY axis direction of the workpiece 20. After the workpiece 20 is leveled, only one angle can be discharged. At this time, the electrode needs to be placed at another angle for discharge. In this way, the undercut holes 30 of the workpiece 20 can be discharged. Although this processing method is less difficult, the workpiece 20 needs to be placed in one more direction and one more reference needs to be processed, which makes the processing process complicated.

[0003] In view of this, it is necessary to provide a processing method of a dual-angle electrode and an electrode structure thereof to solve the above problems. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is that, for a double-angle undercut hole in a workpiece, discharging the electrode by placing the workpiece at two angles in sequence is difficult and the machining accuracy is difficult to control. Alternatively, a reference is made in the XY axis direction of the workpiece, and then the electrode is placed at an angle for discharging. Although this machining method is easy, it requires the workpiece to be placed in an additional direction and an additional reference needs to be machined, resulting in a complex machining process. Therefore, the present invention provides a machining method for a double-angle electrode and an electrode structure to solve the above problems.

[0005] The present invention solves the technical problem by providing a method for processing a dual-angle electrode, comprising:

[0006] S1: Remove the electrode: remove the electrode shape according to the direction of the undercut holes at two angles of the workpiece and add the reference frame;

[0007] S2: Make a reference on the electrode reference: Make a parallel surface in the XYZ axis direction on the reference frame of the electrode;

[0008] S3: Programming: Program the electrodes and make a discharge diagram based on the newly created XYZ axis direction reference;

[0009] S4: Material preparation: Select materials according to the size and quantity of electrodes;

[0010] S5: CNC (Computer Numerical Control) machining: The electrode is machined on a CNC machine according to a programmed procedure;

[0011] S6: EDM (Electro Discharge Machining): Calibrate the electrode according to the XYZ axis reference on the electrode. Taking the center of the bottom of the workpiece as the reference, move the electrode x units in the X axis direction, y units in the Y axis direction, and z units in the Z axis direction to discharge the workpiece.

[0012] Preferably, when making parallel surfaces in the XYZ axis directions on the reference frame of the electrode, the references in the XYZ axis directions are integers, which can avoid errors when making tables during discharge machining.

[0013] In addition, the present invention also provides a dual-angle electrode structure, which is an electrode processed and formed by the above-mentioned methods S1 to S5.

[0014] Preferably, the electrode has a first plane in the X-axis direction, a second plane in the Y-axis direction, and a third plane in the Z-axis direction, and the first plane, second plane and third plane of the electrode are parallel to the XYZ axis directions of the workpiece.

[0015] The beneficial effect of the present invention is that the present invention adopts a structural design of a dual-angle electrode and provides precise discharge correction and positioning in the plane of the electrode XYZ axis direction through a dual-angle electrode processing method, so that the workpiece can complete the processing of undercut holes at two angles with one clamping, effectively improving the discharge efficiency, and this method has low processing difficulty and high processing accuracy.
