How instructions control the operation of a processing device is well known in the art and will not be described in detail here.

[0030] <Method Example> The present disclosure provides a method for processing a bull horn gate, which can be implemented by a control device. Specifically, the method for processing a bull horn gate can be implemented by Figure 1 The control device 1300 shown is implemented.

[0031] Figure 2 Flowchart of a bull horn gate processing method according to an embodiment of the present disclosure.

[0032] like Figure 2 As shown, the method includes steps S2100 to S2300 as shown below: Step S2100 , controlling a numerical control machine tool to process an electrode assembly, wherein the electrode assembly includes a reference platform fixed on a discharge machine platform, a reinforcing column fixed on the reference platform, and a plurality of horn electrodes fixed on the reinforcing column.

[0033] In this embodiment, a CNC machine tool may be controlled to process the mold according to a first processing drawing of the electrode assembly to obtain an electrode assembly that matches the first processing drawing. The first processing drawing may pre-draw an electrode assembly model that represents the specific size and shape of the electrode assembly.

[0034] In one embodiment, the specific structure of the electrode assembly 30 can be as follows Figures 3-5 As shown, it includes a reference platform 31 , a reinforcing column 32 and a plurality of horn electrodes 33 .

[0035] In some embodiments, the electrode assembly is an integrally formed structure, and the positional accuracy of each component is ensured through overall processing, thereby reducing assembly errors and further reducing the error of the horn gate obtained by processing the component to be processed through the electrode assembly. The material of the electrode assembly in this embodiment can be copper or graphite.

[0036] In some embodiments, multiple horn electrodes have synchronous axis references to ensure motion consistency when processing the workpiece to be processed, reduce the risk of reverse installation of the electrode assembly, and improve the qualification rate of the processed products.

[0037] In some embodiments, the method further includes: extracting the center line of the center of the bull horn electrode flow channel of the workpiece to be processed to form a spiral guide curve; constructing the bull horn electrode characteristics according to the spiral guide curve; and constructing an electrode assembly model of the electrode assembly according to the bull horn electrode characteristics.

[0038] On this basis, the CNC machine tool is controlled to process the electrode assembly, including: controlling the CNC machine tool to process the electrode assembly according to the electrode assembly model.

[0039] In this embodiment, the horn gate runner of the workpiece to be processed can be analyzed by three-dimensional modeling software, and its center line can be extracted as a spiral guide curve, which must accurately reflect the spatial direction and size parameters of the gate.

[0040] This spiral guide curve not only provides precise geometric guidance for the spiral forming of the horn electrode, but also directly serves as the basis for trajectory planning during EDM. The intelligent air avoidance design ensures that the machining path is free of interference.

[0041] Furthermore, based on the spiral guide curve, a three-dimensional feature model of a single horn electrode is generated according to the preset discharge gap and machining allowance, including key parameters such as electrode head shape, taper and length.

[0042] In some embodiments, constructing an electrode assembly model of an electrode assembly based on the characteristics of a cow horn electrode may include: In some embodiments, an electrode assembly model of an electrode assembly is constructed based on a bull horn electrode feature, including: performing a translation array operation on the bull horn electrode feature based on a set of workpiece spacings in a workpiece to be processed to obtain an electrode assembly model.

[0043] In this embodiment, according to the arrangement spacing of the workpieces to be processed in the preparation body (i.e., the center distance between adjacent workpieces), a single horn electrode feature is translated into an array operation so that multiple electrodes are evenly distributed according to the workpiece arrangement. At the same time, a reference table and a reinforcing column structure are added. The bottom surface of the reference table is provided with positioning holes that match the discharge machine table. The reinforcing column connects the reference table and the horn electrode to enhance the overall rigidity, thereby finally forming a complete electrode assembly model.

[0044] In some embodiments, the control of the numerical control machine tool is to process the whole electrode assembly according to the above electrode assembly model, and the high-speed milling process is preferred to ensure the integrated molding of the reference table, the reinforcing column and the plurality of horn electrodes. During the processing, it is necessary to ensure that the flatness error of the reference table is less than or equal to the first threshold value; the perpendicularity error of the axis of each horn electrode to the bottom surface of the reference table is less than or equal to the second threshold value; and the spacing error of adjacent horn electrodes is consistent with the workpiece spacing error and is less than or equal to the third threshold value.

[0045] Step S2200, install the electrode assembly on the discharge machine table.

[0046] In the present embodiment, the electrode assembly is fixed on the discharge machine table through the reference table, and the positioning hole can be used to realize fast clamping and ensure the relative position accuracy of the electrode assembly and the discharge machine table.

[0047] In some embodiments, the mechanical arm can be controlled to install the motor assembly processed by the numerical control machine tool on the discharge machine table.

[0048] In some embodiments, the motor assembly can also be manually installed on the discharge machine table by the worker.

[0049] Step S2300, control the discharge machine table to discharge process a group of workpieces to be processed through the electrode assembly, so that the group of workpieces to be processed form horn gates corresponding to the plurality of horn electrodes.

[0050] In the present embodiment, the number of a group of workpieces to be processed can be equal to the number of horn electrodes in an electrode assembly.

[0051] In some embodiments, a group of workpieces to be processed can be arranged on the same material preparation body.

[0052] In the present embodiment, the control of the discharge machine table to discharge process a group of workpieces to be processed through the electrode assembly can include: controlling the electrode assembly to move to a group of workpieces to be processed according to a preset path (such as Z-axis vertical feeding), and when the distance between the electrode assembly and the group of workpieces to be processed is reduced to a discharge gap, controlling the discharge machine table to generate pulse current to break down the medium (usually kerosene or deionized water) and form spark discharge.

[0053] The discharge machine table generates a high temperature of 10000℃ or more at the moment of discharge, so that the surface material of the workpiece to be processed is melted and gasified and is washed away by the working fluid (forming an etching pit), so that a group of workpieces to be processed form horn gates corresponding to the plurality of horn electrodes.

[0054] In the traditional bull horn gate processing process, it is usually necessary to first separately process multiple bull horn electrodes, and then use these electrodes to discharge the mold one by one to form the bull horn gate. Then, the number of bull horn gates processed within the set time and the number of electrode assemblies used can be expressed as 1:1.

[0055] In this embodiment, when the electrode assembly includes N bull horn electrodes, N bull horn gates can be formed simultaneously. Then, the number of bull horn gates processed within a set time and the number of electrode assemblies used can be expressed as 1:N. Wherein N is a positive integer greater than 1.

[0056] Through the embodiments of the present disclosure, the number of electrode assemblies required during the processing of the bull horn gate can be reduced, the operation time for replacing the electrode assembly and the waiting time for workpiece transfer can be reduced, the processing efficiency of the bull horn gate can be improved, and the qualification rate of the processed products can be improved.

[0057] In some embodiments, controlling an electrical discharge machine to perform electrical discharge machining on a group of workpieces to be machined using an electrode assembly includes: using a bullhorn electrode of the electrode assembly as a finishing electrode, controlling the electrical discharge machine to perform finish machining on a first group of workpieces to be machined using the electrode assembly; and using the bullhorn electrode of the electrode assembly as a roughing electrode, controlling the electrical discharge machine to perform rough machining on a second group of workpieces to be machined using the electrode assembly. The first group of workpieces to be machined are workpieces to be machined that have undergone rough machining, and the second group of workpieces to be machined are workpieces to be machined that have not undergone rough machining.

[0058] In this embodiment, each group of components to be processed is processed by a combination of roughing and fine processing.

[0059] The first set of components to be processed may be pre-roughly processed using other electrode assemblies, and then the EDM machine is controlled to use the electrode assembly obtained in step S2100 to perform EDM to remove most of the excess of the first set of components to be processed.

[0060] Keep the position of the first set of electrode assemblies unchanged and replace them with new electrode assemblies. By adjusting the discharge parameters (such as reducing the current and shortening the pulse width), the electrode assembly is used as the finishing electrode to complete the final forming of the bull horn gate of the first set of components to be processed.

[0061] On this basis, the position of the electrode assembly remains unchanged, and the first group of electrode assemblies is replaced with the second group of electrode assemblies. By adjusting the discharge parameters (such as increasing the current and increasing the pulse width), the electrode assembly is used as a rough machining electrode to remove most of the excess of the second group of components to be processed.

[0062] In this embodiment, when the horn electrode of the electrode assembly is used as a finishing electrode, the discharge machine can be controlled to discharge according to the finishing parameters, and precise dimensional electro-erosion can be performed to ensure the dimensional accuracy and surface integrity of the first group of components to be processed.

[0063] When the horn electrode of the electrode assembly is used as a rough machining electrode, the discharge machine can be controlled to discharge according to the rough machining parameters to accelerate the electro-corrosion process and quickly remove the material of the second group of components to be processed.

[0064] Through this embodiment, the horn electrode of an electrode assembly is first used as a finishing electrode, which can prevent the horn electrode from being lost before finishing and improve the processing accuracy of the horn gate. The horn electrode of the electrode assembly after finishing is then used as a rough processing electrode, which can improve the utilization rate of the electrode assembly, reduce the processing cost of the horn gate, and improve the processing efficiency of the horn gate.

[0065] <Device Example> This embodiment provides a bull horn gate processing device, such as Figure 6 As shown, the bullhorn gate processing device 6000 may include a first control module 6100 , an electrode installation module 6200 and a second control module 6300 .

[0066] The first control module 6100 is used to control a CNC machine tool to process an electrode assembly, wherein the electrode assembly includes a reference platform fixed on a discharge machine, a reinforcing column fixed on the reference platform, and a plurality of horn electrodes fixed on the reinforcing column.

[0067] The electrode installation module 6200 is used to install the electrode assembly on the discharge machine.

[0068] The second control module 6300 is used to control the discharge machine to perform discharge processing on a group of workpieces to be processed through the electrode assembly, so that the group of workpieces to be processed form horn gates corresponding to the multiple horn electrodes one by one.

When the distance between the electrode assembly and the group of workpieces to be machined is reduced to an electrical discharge gap, the control device controls the electrical discharge machine to perform electrical discharge machining on the group of workpieces to be machined by generating a pulse current.
