Description

Technical Field

[0001] This utility model relates to the field of electrical discharge equipment technology, and in particular to an electrical discharge machine. Background Technology

[0002] In an electrical discharge machine (EDM), a large amount of heat energy is instantaneously concentrated in the micro-channel of the discharge, causing a rapid increase in temperature and a sharp change in pressure. This causes a small amount of metal material on the workpiece surface to melt and vaporize, splashing into the working fluid, where it quickly condenses and forms solid metal particles that fall into the fluid. This leaves a tiny pit on the workpiece surface. The discharge then pauses briefly, and the working fluid between the two electrodes returns to an insulating state. By continuously repeating this process, a significant amount of metal can be removed, achieving precise machining of the workpiece. During operation, the working fluid in an EDM machine generates continuously high temperatures; therefore, efficient heat dissipation for the EDM machine is a key technical challenge that needs to be addressed.

[0003] Existing four-head EDM machines typically have a base on each side of the worktable, and these bases are integral structures, with two EDM heads mounted on each base. A liner is placed between the two bases, and the working fluid container rests on the liner. The existing EDM machine's liner has poor heat dissipation, and because the bases on both sides of the liner are integral structures, heat dissipation is further affected, resulting in high machine temperatures during operation and severely impacting the user experience. Utility Model Content

[0004] This invention addresses the technical problem of poor heat dissipation in existing four-head EDM machines by providing a new type of EDM machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electrical discharge machine includes: a base, a first support member, a second support member, a heat dissipation liner, a three-axis motion mechanism, and a discharge head;

[0007] The upper end of the base is provided with a first platform, a second platform, and a third platform; the first platform is located on one side of the base, the second platform is located on the other side of the base, and the third platform is located between the first platform and the second platform; multiple heat dissipation fins are provided at the connection between the first platform and the third platform; multiple heat dissipation fins are provided at the connection between the third platform and the second platform.

[0008] The first support member is fixed on the first platform, and the second support member is fixed on the second platform; two EDM heads are respectively mounted on the first support member through two of the three-axis motion mechanisms; two EDM heads are respectively mounted on the second support member through two of the three-axis motion mechanisms; the heat dissipation liner is fixed on the third platform, and the upper end of the heat dissipation liner is used to set the working fluid container.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the upper height of the first support member and the second support member is 1-1.2 times the upper height of the heat dissipation liner.

[0011] Furthermore: the first platform and the second platform have the same height, and the third platform has a greater height than the first platform and the second platform.

[0012] Furthermore, the upper end of the heat dissipation liner is provided with multiple crisscrossing heat dissipation grooves.

[0013] Furthermore, the interior of the base is designed with a hollow structure.

[0014] Furthermore: the first support member is detachably fixed to the first platform, the second support member is detachably fixed to the second platform; and the heat dissipation liner is detachably fixed to the third platform.

[0015] Compared with the prior art, the EDM machine provided by this utility model has the following beneficial effects:

[0016] The EDM machine provided by this utility model has multiple heat dissipation fins at the connection between the first platform and the third platform, and multiple heat dissipation fins at the connection between the third platform and the second platform. The heat emitted from the working fluid container is conducted to the heat dissipation liner, and the heat is conducted to the heat dissipation fins through the heat dissipation liner. The heat dissipation fins increase the contact area with the surrounding air, which greatly improves the heat dissipation effect of the equipment.

[0017] Furthermore, in the EDM machine provided by this utility model, the upper height of the first support member and the second support member is 1-1.2 times the upper height of the heat dissipation liner. By setting the height of the first support member and the second support member slightly higher than the heat dissipation liner, the heat dissipated from the heat dissipation liner can be dissipated from the blank area between the three-axis motion mechanism set on the first support member and the second support member, which increases the air circulation around the heat dissipation liner and further improves the heat dissipation effect of the equipment.

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0023] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below" or "below" of the other element or feature will be oriented "above" the other element or feature. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0024] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediary element.

[0025] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0026] This utility model embodiment provides an electrical discharge machine, see [link]. Figure 1 and Figure 2 It mainly includes: a base 1, a first support component 3, a second support component 4, a heat dissipation liner 2, a three-axis motion mechanism 5, and a spark head 6. The connections and functions of each component are as follows:

[0027] The base 1 serves as the supporting structure for the entire EDM machine. The interior of the base 1 is designed with a hollow structure to improve heat dissipation. Necessary reinforcing ribs are incorporated within the base 1 to ensure its load-bearing capacity for the equipment above it. The upper end of the base 1 is equipped with a first platform 8, a second platform 10, and a third platform 9. The first platform 8 is located on one side of the base 1, the second platform 10 on the other side, and the third platform 9 between the first platform 8 and the second platform 10, symmetrically arranged. Multiple heat dissipation fins 7 are located at the connection points between the first platform 8 and the third platform 9; multiple heat dissipation fins 7 are also located at the connection points between the third platform 9 and the second platform 10; the heat dissipation fins 7 on the same side are evenly distributed. Heat dissipated from the working fluid container is conducted to the heat dissipation liner 2, and then through the heat dissipation liner 2 to the heat dissipation fins 7. The heat dissipation fins 7 increase the contact area with the surrounding air, improving the heat dissipation effect of the equipment. Furthermore, the heat dissipation fins 7 also provide reinforcement, further enhancing the structural stability of the equipment.

[0028] The first support member 3 is detachably fixed to the first platform 8, and the second support member 4 is detachably fixed to the second platform 10. The first support member 3 and the second support member 4 are symmetrically arranged. Two EDM heads 6 are mounted on the first support member 3 via two three-axis motion mechanisms 5; two EDM heads 6 are mounted on the second support member 4 via two three-axis motion mechanisms 5. The heat dissipation liner 2 is fixed to the third platform 9. The upper end of the heat dissipation liner 2 is used to set the working fluid container. The upper end of the heat dissipation liner 2 is provided with multiple crisscrossing heat dissipation grooves 11 to further improve the heat dissipation effect of the heat dissipation liner 2. To further improve the heat dissipation effect of the first support member 3 and the second support member 4, in this embodiment, the first support member 3 and the second support member 4 are set as hollow structures. Multiple reinforcing ribs are provided in the hollow structure to ensure the structural strength of the first support member 3 and the second support member 4.

[0029] In a preferred embodiment provided by this utility model, see [link to previous embodiment]. Figure 1The upper height of the first support member 3 and the second support member 4 is set to 1-1.2 times the upper height of the heat dissipation liner 2. Setting the height of the first support member 3 and the second support member 4 slightly higher than the heat dissipation liner 2 allows heat dissipated from the heat dissipation liner 2 to dissipate through the blank area between the triaxial motion mechanism 5 mounted on the first support member 3 and the second support member 4. This reduces the obstruction effect of the first support member 3 and the second support member 4 on the heat dissipation liner 2 inside them, thus improving the heat dissipation effect.

[0030] In a preferred embodiment provided by this utility model, see [link to previous embodiment]. Figure 1 The first platform 8 and the second platform 10 have the same height, while the third platform 9 has a greater height than the first platform 8 and the second platform 10. Setting the height of the third platform 9 to be greater than that of the first platform 8 and the second platform 10 can reduce the height of the working fluid container and reduce the stroke of the three-axis motion mechanism 5 in the Z direction.

[0031] See Figure 1 and Figure 2 The EDM machine provided in this embodiment of the present invention has at least the following beneficial effects or advantages:

[0032] The EDM machine provided in this embodiment of the utility model has multiple heat dissipation fins 7 at the connection between the first platform 8 and the third platform 9, and multiple heat dissipation fins 7 at the connection between the third platform 9 and the second platform 10. The heat emitted from the working fluid container is conducted to the heat dissipation liner 2, and the heat is conducted to the heat dissipation fins 7 through the heat dissipation liner 2. The heat dissipation fins 7 increase the contact area with the surrounding air, which greatly improves the heat dissipation effect of the equipment.

[0033] The EDM machine provided in this embodiment has an upper height of 1-1.2 times that of the upper height of the heat dissipation liner 2. By setting the height of the first support member 3 and the second support member 4 to be slightly higher than that of the heat dissipation liner 2, the heat dissipated from the heat dissipation liner 2 can be dissipated from the blank area between the three-axis motion mechanism 5 provided on the first support member 3 and the second support member 4, which increases the air circulation around the heat dissipation liner 2 and further improves the heat dissipation effect of the equipment.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
