Figure 5

[0030] The processing mold of this embodiment is mainly used for producing copper profiles for battery wire joints. The feature is to solve the problem of high cost and low processing efficiency caused by large processing allowance and much processing waste in the prior art which generally uses large copper bars for turning. This embodiment aims to use an extrusion process to integrally form a copper profile raw material that can be used for processing battery wire joints, thereby solving the problems of one-piece forming, no welding points, and not easy to fall off, and reducing processing allowance and processing cost.

[0031] The processing flow of the processing mold extrusion formed in this embodiment includes:

[0032] ​​①Start the device extrusion shaft 3 relative to the outer die cylinder 4 retreat, the top shaft 5 from the extrusion channel 2 of the outer die cylinder 4, at this time, the installation of the embodiment processing die extruder state as shown in Figure 2 And Figure 3 ;

[0033] ②Subsequently, by the external mechanical arm or clamp, the preheating softening of copper raw materials from the discharge port 81 into the receiving cylinder 8, then, start the top shaft 5 and extrusion shaft 3, so that both move to the middle of the copper raw materials;

[0034] ③The top shaft 5 moves the copper raw materials from the rear end of the outer die cylinder 4 into the extrusion channel 2, and the top shaft 5 is kept stationary after extending a distance, the length of the extension is about the top end of the top shaft 5 into the outer die cylinder 4 a certain distance, at this time, the copper raw materials are completely located in the extrusion channel 2, and the top shaft 5 closes the opening on one side of the extrusion channel 2, in addition, at the same time of the above action, the extrusion shaft 3 of the other end of the extrusion channel 2 with the extrusion die 33 from the other side into the extrusion channel 2, until the copper raw materials and to apply extrusion pressure;

[0035] ④As above, at this time based on the copper raw materials in the softening state, the strong extrusion force of the extrusion shaft 3 will make it produce deformation, and the whole extrusion channel 2 at this time, only the copper profile shape of the extrusion opening of the extrusion die 33 can be extruded, so the copper profile will be extruded from the middle of the extrusion die 33, the extruded copper profile into the extrusion cylinder 32, and continuously extend backward, and then be taken by the rear receiving device;

[0036] ⑤In addition, after the extrusion shaft 3 is fed a certain distance, the top column 36 of the extrusion cylinder 32 is in contact with the stepped end surface 34 of the outer die cylinder 4, and the axial movable assembly of the outer die cylinder 4 is linked with the extrusion shaft 3, so that the extrusion shaft 3 and the outer die cylinder 4 move synchronously relative to the top shaft 5, the movement of the two towards the top shaft 5 makes the cavity of the extrusion channel 2 compressed, so that the copper raw materials inside continuously form extrusion into copper profile based on the space reduction;

[0037] ⑥After extrusion, the top shaft 5 remains stationary while the outer die cylinder 4 moves a certain distance towards the top shaft 5, the distance size is that the front end of the top shaft 5 is exposed to the outer die cylinder 4, at the same time, the extrusion shaft 3 retreats a certain distance, then the cutter located at the end of the top shaft 5 a little bit ahead is started, which cuts off the copper profile radially, so that it is separated from the remaining end of the copper raw materials, then the external device takes away the copper profile, and the extruded copper residue 9 and the cut residual piece 91 fall into the lower waste frame;

[0038] ⑦Subsequently, the external device takes away the copper profile, and the extrusion shaft 3, the outer die cylinder 4 and the top shaft 5 of the device body 1 are automatically reset after the copper residue 9 falls into the frame;

[0039] ⑧ Repeat steps ①-⑦ for the next extrusion.

[0040] It is worth noting that during the extrusion of the copper profile in the above steps, the cooling element 6 provided on the extrusion cylinder 32 can be activated as needed to spray water or air from the cooling port 61 to cool the copper profile. The movement of the outer mold cylinder 4 and the extrusion shaft 3 can be achieved by setting sensors or directly limiting the length of the drive shaft in the injection molding, die casting, and extrusion dies of existing technologies, so as to trigger multiple drive units to start sequentially or simultaneously, thereby realizing the power action of the above equipment steps.

[0041] It is worth noting that in the above structure, a top block 51 is also provided at the front end of the top shaft 5. The purpose of the top block 51 is to prevent the end of the extrusion shaft 3 from directly abutting against the top shaft 5 and completely squeezing the copper material. This setting can avoid the problem of material jamming during extrusion. The principle is as follows: Considering the limitations of the existing extrusion technology, there will still be a very thin layer of tubular copper material between the extrusion shaft 3 and the inner wall of the outer mold cylinder 4. This layer of tubular copper material generally requires a special material ejection structure to eject it. However, this embodiment not only provides a cutting piece 35 to cut the rear end so that it can fall off naturally after the front end is extruded, but also provides a top block on the top shaft 5. 51, and a cutting device is set on one side of the outer mold cylinder 4 (the cutting structure refers to the cutting machine of the prior art, and the setting position and radial cutting state are shown in the attached figure). Due to the setting of the top block 51, after the extrusion is completed, the end of the copper raw material will still have a section remaining in the axial direction on the side of the top shaft 5. Therefore, when the outer mold cylinder 4 continues to move towards the top shaft 5 after the extrusion is completed, the copper raw material will be separated from the outer mold cylinder 4 due to the restriction of the top shaft 5 and will not move with it. After the outer mold cylinder 4 moves to expose the top shaft 5, the cutting device is started to radially cut the remaining copper raw material. After losing the radial support of the outer mold cylinder 4, the copper residue will fall into the waste box with gravity, completing the material removal.

[0042] Furthermore, the copper profile processing mold in this embodiment achieves copper profile extrusion processing by improving the coordinated action of the top shaft, outer mold cylinder, and extrusion shaft within the mold. Based on the setting of the top block, the outer mold cylinder continues to move after extrusion. The presence of the top block ensures that a certain amount of residual material remains after extrusion, enabling rapid material removal and cleaning of the waste material in the outer mold cylinder. This avoids incomplete material removal leading to material jamming in the outer mold cylinder, which can cause residual material to mix with new material, ultimately affecting the quality of the extruded product. Because automatic waste material removal may result in material jamming, it also leads to the frequent need for staff to clean and maintain the outer mold cylinder. This eliminates the cleaning steps for staff in the workflow, avoiding frequent machine downtime for maintenance due to material jamming, which is also a way to indirectly improve work efficiency.

[0043] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
