Abstract
Description
Technical Field
[0001] This invention relates to an irregularly shaped electrode assembly and its processing method, belonging to the field of precision machining technology. Background Technology
[0002] Existing electrodes commonly use copper as the main material. However, copper is easily deformable, making it difficult to manufacture even slightly larger tool electrodes. The dimensions of the tool electrode cannot be easily completed in one operation, making it difficult to meet the requirements of electrical discharge machining (EDM). Moreover, in some molds with large overall structures and depths, electrodes with end faces higher than the electrode shape are increasingly meeting production needs. This is because the overall length of the electrode is relatively large, making it difficult and time-consuming to manufacture. In addition, there is a lot of copper material wastage, resulting in high production costs. Manufacturing entirely new electrodes requires the use of entirely new electrode shapes, which undoubtedly increases production costs. Therefore, manufacturing electrodes that meet the requirements based on existing electrode shapes has become a major challenge. To address this, we provide a non-standard electrode that is small in size, easy to manufacture, and can be manufactured using existing electrode shapes. Summary of the Invention
[0003] The purpose of this invention is to provide an irregularly shaped electrode assembly and a processing method to solve the above-mentioned problems.
[0004] To achieve the above objectives, the present invention provides the following technical solution: an irregularly shaped electrode assembly, the irregularly shaped electrode assembly comprising an electrode body, an irregularly shaped electrode, and an irregularly shaped reference frame, wherein the length direction of the irregularly shaped electrode and the length direction of the irregularly shaped reference frame are arranged perpendicular to each other, the irregularly shaped electrode is inserted into the side of the electrode body along the length direction of the electrode body, the irregularly shaped reference frame has a convex plate structure, the irregularly shaped reference frame extends in a direction away from the side of the electrode body, and the maximum distance between the end face of the irregularly shaped reference frame away from the irregularly shaped electrode and the connection surface between the irregularly shaped electrode and the electrode body is not greater than one-third of the maximum distance between the end face of the irregularly shaped reference frame and the connection surface between the electrode body and the electrode body.
[0005] Furthermore, the cross-sectional area of the irregularly shaped electrode decreases from one of the avoidance surfaces toward the other avoidance surface.
[0006] Furthermore, the connection surface between the irregularly shaped electrode and the electrode body is an inclined surface, and it tends to rise from the side with the largest cross-sectional area of the irregularly shaped electrode towards the side with the smallest cross-sectional area.
[0007] Furthermore, the irregularly shaped electrode is disposed on the short side of the irregularly shaped reference frame, and the two sides are coplanar.
[0008] Furthermore, a frustum-shaped insertion groove is formed recessed from the connecting surface of the irregular electrode, and an insertion end is formed in the frustum-shaped insertion groove. A semi-cylindrical protrusion that adapts to part of the frustum-shaped insertion groove is formed on the connecting surface of the electrode body facing the direction of the irregular electrode, and the insertion end is snapped onto the side of the electrode body.
[0009] Furthermore, the plug-in end is semi-cylindrical, and an arc-shaped groove adapted to the shape of the plug-in end is formed on the side of the electrode body.
[0010] The present invention also provides a processing method, characterized in that it is applicable to processing irregularly shaped electrodes as described in any one of claims 1 to 6, the processing method comprising:
[0011] Step A: Remove the electrode shape and machine the irregular reference frame on the irregular electrode blank;
[0012] Step B: Edit the machining program for the irregular electrode with the long side of the irregular reference frame as the X-axis reference direction and the side perpendicular to the long side as the Y-axis reference direction, and mark the discharge diagram with the X-axis of the irregular reference frame divided into Y-axis single sides.
[0013] Step C: The irregularly shaped electrode blank is machined on a CNC machine tool according to the machining program;
[0014] Step D: Perform EDM discharge machining on the irregularly shaped electrode blank after it has been processed by the CNC machine tool according to the discharge pattern.
[0015] Furthermore, step B also includes: performing CNC simulation machining on the 3D model of the irregular electrode to generate a CNC machining program.
[0016] Furthermore, step C also includes: preparing irregularly shaped electrode blanks according to the material preparation list.
[0017] Furthermore, the preparation of irregular electrode blanks according to the material preparation list includes: preparing materials according to the size and quantity of the irregular electrodes.
[0018] The beneficial effects of this invention are as follows: This application provides an irregularly shaped electrode assembly and processing method, which allows the irregularly shaped electrode and the irregularly shaped reference frame to be completely arranged on the side of the electrode body. The maximum height of both can be less than one-third of the maximum distance between the connection surface between the irregularly shaped electrode and the electrode body and the farthest end face of the electrode body. This solves the problem that the original reference frame needs to be set on the outside of the end face of the electrode body, resulting in a long overall length of the electrode. This reduces the processing difficulty of the irregularly shaped electrode, saves copper material, and improves the processing efficiency of the irregularly shaped electrode. At the same time, setting the irregularly shaped reference frame as a convex plate structure facilitates the installation of the irregularly shaped electrode.

The irregular electrode 30 is inserted into the side of the electrode body 10 along the length direction of the electrode body 10. The irregular reference frame 30 has a convex plate structure and extends in a direction away from the side of the electrode body 10. The maximum distance between the end face of the irregular reference frame 30 away from the irregular electrode 30 and the connection surface between the irregular electrode 30 and the electrode body 10 is not greater than one-third of the maximum distance between the end face of the irregular reference frame 30 and the connection surface between the electrode body 10 and the irregular electrode 30.
[0027] In one embodiment, the cross-sectional area of the irregular electrode 30 decreases from one clearance surface toward the other clearance surface.
[0028] In one embodiment, the connection surface between the irregular electrode 30 and the electrode body 10 is an inclined surface, and it has an upward trend from the side with the largest cross-sectional area of the irregular electrode 30 toward the side with the smallest cross-sectional area.
[0029] In one embodiment, the irregularly shaped electrode 30 is disposed on the short side of the irregularly shaped reference frame 30, and the sides of both are coplanar. This arrangement facilitates the fit between the sides of the irregularly shaped electrode 30 and the irregularly shaped reference frame 30 and the sides of the electrode body 10, making processing easier.
[0030] In one embodiment, a frustum-shaped insertion groove 31 is formed recessed in the connecting surface of the irregular electrode 30, and an insertion end 32 is formed in the frustum-shaped insertion groove 31. A semi-cylindrical protrusion that adapts to the frustum-shaped insertion groove 31 is formed on the connecting surface of the electrode body 10 facing the direction of the irregular electrode 30, and the insertion end 32 is snapped onto the side of the electrode body 10.
[0031] In one embodiment, the plug end 32 is semi-cylindrical, and an arc-shaped groove adapted to the shape of the plug end 32 is formed on the side of the electrode body 10.
[0032] The present invention also provides a processing method, characterized in that it is applicable to processing irregularly shaped electrodes 30 as claimed in any one of claims 1 to 6, and the processing method includes:
[0033] Step A: Remove the electrode body 10 and machine the irregular reference frame 30 on the irregular electrode 30 blank;

[0040] This application provides an irregularly shaped electrode assembly and processing method, which allows the irregularly shaped electrode and the irregularly shaped reference frame to be completely arranged on the side of the electrode body. The maximum height of both can be less than one-third of the maximum distance between the connection surface between the irregularly shaped electrode and the electrode body and the farthest end face of the electrode body. This solves the problem that the original reference frame needs to be set on the outside of the end face of the electrode body, resulting in a long overall length of the electrode. This reduces the processing difficulty of the irregularly shaped electrode, saves copper material, and improves the processing efficiency of the irregularly shaped electrode. At the same time, the irregularly shaped reference frame is set as a convex plate structure, which facilitates the installation of the irregularly shaped electrode.
