Description

Technical Field

[0001] This utility model relates to the field of aluminum extrusion die manufacturing, and in particular to an electro-erosion perforation electrode for a multi-core aluminum extrusion die. Background Technology

[0002] Multi-core aluminum extrusion dies typically have multiple ribs, and adjacent ribs are usually machined by electrode erosion. This usually requires multiple erosion processes with a single electrode, frequent clamping and correction, resulting in extremely low efficiency. If each EDM machine is used to process the set through holes individually, the EDM machine must be configured according to the number of holes, which not only increases production costs and occupies a large area, but also makes it difficult to guarantee the processing accuracy between different EDM machines, and easily leads to defective products. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an electro-erosion perforation electrode for a multi-core aluminum extrusion die, which has the advantages of high processing efficiency and high processing precision.

[0004] According to a first aspect of the present invention, a multi-core aluminum extrusion die electro-erosion perforation electrode includes a mounting base and an electro-erosion assembly. The mounting base is a conductor. The electro-erosion assembly includes at least two electro-erosion arms spaced apart from each other on the mounting base. One end of each electro-erosion arm is mounted to the mounting base, and the other end of each electro-erosion arm is a suspended structure. The area of ​​the smallest cross-section of the mounting base perpendicular to the spaced distribution direction of the electro-erosion arms is S1, and the area of ​​the smallest cross-section of each electro-erosion arm perpendicular to its extension direction is S2. The sum of S2 of all the electro-erosion arms is less than S1.

[0005] The electro-erosion perforation electrode of the multi-core aluminum extrusion die according to the present invention has at least the following beneficial effects: the electro-erosion arms on the mounting base are set according to the number and position of the processing holes on the multi-core aluminum extrusion die, which can complete the multi-hole processing at one time, reduce the number of clamping and correction times, and have high processing efficiency and accuracy. Furthermore, by setting the minimum cross-sectional area of ​​the mounting base to be greater than the sum of the cross-sectional areas of all the electro-erosion arms, it is ensured that the mounting base can provide sufficient power to the electro-erosion arms, thus ensuring the processing effect of simultaneous electro-erosion of multiple holes.

[0006] According to some embodiments of the present invention, the mounting base is an elongated structure, and the electro-erosion arms are spaced apart along the length direction of the mounting base.

[0007] According to some embodiments of the present invention, the electro-erosion arm is detachably mounted on the mounting base.

[0010] According to some embodiments of the present invention, the dovetail sliding part is provided with a dividing groove that extends along its sliding direction and divides it into two parts. The dividing groove is provided with a threaded hole that extends along the sliding direction of the dovetail sliding part. The positioning mechanism is a screw that cooperates with the threaded hole.

The dividing groove is provided with a pin hole that extends along the sliding direction of the dovetail sliding part. The positioning mechanism is a pin that cooperates with the pin hole. When the pin is inserted into the pin hole, the dovetail sliding part can expand to both sides of its sliding direction.

[0012] According to some embodiments of the present invention, when the dovetail sliding part is engaged with the dovetail groove, there is a gap between the bottom of the dovetail sliding part and the bottom of the dovetail groove. When the dovetail sliding part expands to both sides in its sliding direction, it can pull the lower end of the electro-erosion arm to fit tightly against the mounting base.

[0013] According to some embodiments of the present invention, the areas of the sidewalls of the two sets of inclined sides of the trapezoidal structure corresponding to the dovetail sliding part are S3 and S4, respectively, wherein S3+S4>S1.

[0028] The following is for reference. Figures 1 to 6 This invention describes an electro-erosion perforated electrode for a multi-core aluminum extrusion die according to an embodiment of the present invention.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 6As shown, the electro-erosion perforation electrode of the multi-core aluminum extrusion die according to an embodiment of the present invention includes a mounting base 100 and an electro-erosion assembly. The mounting base 100 is a conductor. The electro-erosion assembly includes at least two electro-erosion arms 200 spaced apart from each other on the mounting base 100. One end of the electro-erosion arm 200 is mounted to the mounting base 100, and the other end of the electro-erosion arm 200 is a suspended structure. The area of ​​the minimum cross-section of the mounting base 100 perpendicular to the spaced distribution direction of the electro-erosion arms 200 is S1, and the area of ​​the minimum cross-section of the electro-erosion arm 200 perpendicular to its extension direction is S2. The sum of S2 of all electro-erosion arms 200 is less than S1.

[0030] The electro-erosion arms 200 on the mounting base 100 are set according to the number and position of the machining holes on the multi-core aluminum extrusion die, which can complete multi-hole machining at one time, reducing the number of clamping and correction times, and achieving high machining efficiency and accuracy. Furthermore, by setting the minimum cross-sectional area of ​​the mounting base 100 to be greater than the sum of the cross-sectional areas of all the electro-erosion arms 200, it is ensured that the mounting base 100 can provide sufficient power to the electro-erosion arms 200, thus ensuring the machining effect of simultaneous electro-erosion of multiple holes.

[0031] In some embodiments of this utility model, the mounting base 100 is a conductor and is made of conductive materials, such as copper, nickel, tungsten copper alloy or other conductive alloys.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments of this utility model, the mounting base 100 has an elongated structure, and the electro-erosion arms 200 are spaced apart along the length direction of the mounting base 100 to form a comb-shaped structure. The electro-erosion arms 200 are spaced apart on the mounting base 100 and extend out from the mounting base 100 to form electro-erosion electrodes.

[0033] Specifically, the mounting base 100 is a cylindrical or cuboid structure, so that multiple electro-erosion arms 200 are distributed at intervals. The electro-erosion arms 200 are also elongated structures, and their cross-sectional shape corresponds to the shape of the required electro-erosion hole, thereby meeting the electro-erosion processing requirements of the corresponding hole position.

[0034] In some embodiments of this utility model, the electro-erosion arm 200 is detachably mounted on the mounting base 100 to meet the replacement requirements of the electro-erosion arm 200.

[0035] During the actual implementation process, the electro-erosion arm 200 will experience some wear and tear. By using a detachable design, the electro-erosion arm 200 can be easily replaced. In addition, the number of electro-erosion arms can be increased or decreased, or the type of electro-erosion arm can be changed, depending on the number and shape of the holes being processed.

[0036] In some embodiments of this utility model, the electro-erosion arm 200 can be detachably installed onto the mounting base 100 via a threaded connection structure, a plug-in structure, a snap-fit ​​structure, a sliding installation structure, or the like.

[0037] In some embodiments of this utility model, the electro-erosion arm 200 is slidably disposed on the mounting base 100, and a positioning mechanism capable of positioning the relative position of the electro-erosion arm 200 and the mounting base 100 is provided to facilitate flexible adjustment.

[0038] Specifically, during use, the sliding structure can be used to adjust the electro-erosion arm 200, and the position of the electro-erosion arm 200 can be locked by the positioning mechanism, so that the electro-erosion processing of multiple holes can be completed in one go, and the processing accuracy and efficiency can be guaranteed.

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments of this utility model, one end of the electro-erosion arm 200 is provided with a dovetail sliding part 210 with a trapezoidal cross-section, and the mounting base 100 is provided with a dovetail groove 101 corresponding to the dovetail sliding part 210. The sliding requirements of the electro-erosion arm 200 can be met by the sliding cooperation between the dovetail sliding part 210 and the dovetail groove 101.

[0040] Specifically, the dovetail sliding part 210 is tightly fitted with the dovetail groove 101 to ensure conductivity. The dovetail sliding part 210 is not included in the calculation of the cross-sectional area S2 of the electro-erosion arm 200.

[0041] It is understood that, in some embodiments of this utility model, the electro-erosion arm 200 and the mounting base 100 can also achieve a sliding fit through a T-shaped slide rail and groove structure.

[0042] like Figure 4 , Figure 5 As shown, in some embodiments of this utility model, the dovetail sliding part 210 is provided with a dividing groove 211 that extends along its sliding direction and divides it into two parts. A threaded hole 212 extending along the sliding direction of the dovetail sliding part 210 is provided at the dividing groove 211. The positioning mechanism is a screw that cooperates with the threaded hole 212. When the screw is screwed into the threaded hole 212, it can cause the dovetail sliding part 210 to expand to both sides of its sliding direction, so that the dovetail sliding part 210 is tightly fitted with the dovetail groove 101 to position the position of the electro-erosion arm 200 and at the same time ensure the conductivity effect.

[0043] Specifically, the partition groove 211 divides the dovetail sliding part 210 into two halves along the sliding direction of the dovetail sliding part 210, that is, the dovetail sliding part 210 with an isosceles trapezoidal cross section is divided into two right-angled trapezoids. When the screw is screwed into the partition groove 211, the dovetail sliding part 210 divided into two halves can be opened up, so that the inclined surface of the dovetail sliding part 210 abuts against the corresponding inclined surface of the dovetail groove 101, thereby fixing the dovetail sliding part 210 and maintaining a good electrical connection.

[0044] In some embodiments of this utility model, the dovetail sliding part 210 is provided with a dividing groove 211 that extends along its sliding direction and divides it into two parts. A pin hole extending along the sliding direction of the dovetail sliding part 210 is provided at the dividing groove 211. The positioning mechanism is a pin that cooperates with the pin hole. When the pin is inserted into the pin hole, the dovetail sliding part 210 can expand to both sides of its sliding direction, so that the dovetail sliding part 210 is tightly fitted with the dovetail groove 101 to position the position of the electro-erosion arm 200 and at the same time ensure the conductivity effect.

[0045] Specifically, the partition groove 211 divides the dovetail sliding part 210 into two halves along the sliding direction of the dovetail sliding part 210, that is, the dovetail sliding part 210 with an isosceles trapezoidal cross section is divided into two right-angled trapezoids. When the pin is inserted into the partition groove 211, the dovetail sliding part 210 divided into two halves can be opened up, so that the inclined surface of the dovetail sliding part 210 abuts against the inclined surface of the dovetail groove 101, thereby fixing the dovetail sliding part 210 and maintaining a good electrical connection.

[0046] like Figure 4 As shown, in some embodiments of this utility model, when the dovetail sliding part 210 and the dovetail groove 101 are engaged, there is a gap between the bottom of the dovetail sliding part 210 and the bottom of the dovetail groove 101. When the dovetail sliding part 210 expands to both sides in its sliding direction, it can pull the lower end of the electro-erosion arm 200 to fit tightly against the mounting base 100, thereby ensuring the contact effect between the two side walls 213 of the dovetail sliding part 210 and the two side walls of the dovetail groove 101, so that the mating surfaces can fit tightly to ensure the conductivity and fixing effect.

[0047] Specifically, the sidewall 213 of the dovetail sliding part 210 and the sidewall of the dovetail groove 101 are inclined surfaces. When they are pressed together, the dovetail sliding part 210 tends to move downward. The gap between the bottom of the dovetail sliding part 210 and the bottom of the dovetail groove 101 is reserved as a deformation gap when the dovetail sliding part 210 is pressed downward, so that the lower end of the electro-erosion arm 200 can be pulled tightly to the end face of the mounting base 100 to ensure the conductivity effect.

[0048] In some embodiments of this utility model, the areas of the sidewalls 213 of the two sets of inclined sides of the trapezoidal structure of the dovetail sliding part 210 are S3 and S4, respectively, wherein S3+S4>S1, so that the dovetail sliding part 210 has a large sidewall area to ensure the conductivity between the electro-erosion arm 200 and the mounting base 100.

[0049] Specifically, the aforementioned area condition is manifested in that the dovetail sliding part 210 has a large downward extension depth, so that the dovetail sliding part 210 and the dovetail groove 101 have a larger contact surface, ensuring the conductivity effect.

[0050] like Figure 1 , Figure 2As shown, in some embodiments of this utility model, the dovetail groove 101 is connected to at least one end face of the mounting base 100 to facilitate the removal of the electro-erosion arm 200 and realize the detachable installation of the electro-erosion arm 200.

[0051] Specifically, the dovetail groove 101 extends through the mounting base 100 along its length. Screws can be screwed into the threaded holes 212 from both ends of the dovetail groove 101 with the help of tools, which facilitates the sliding, positioning and disassembly of the electro-erosion arm 200.

[0052] Of course, this invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
