Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] The following is for reference. Figures 1 to 2 This invention describes an embossing apparatus and an embossing process according to embodiments of the present invention.

[0026] like Figures 1 to 2As shown, the embossing device according to a first aspect embodiment of the present invention includes an upper stamping die and a lower stamping die distributed vertically. The upper stamping die includes an upper die module and an embossing die connected to the upper die module. The embossing die includes a die body 100. The two ends of the die body 100 are a first end 101 and a second end 102, respectively. The end face of the second end 102 is formed with a plurality of uniformly arranged protrusions 103. The cross-sectional area of ​​the protrusions 103 gradually increases from the end away from the first end 101 to the end closer to the first end 101. A positioning part 104 for connecting and positioning with the upper die of a stamping machine is provided on one side of the die body 100.

[0027] Understandably, this embossing device includes an upper stamping die and a lower stamping die distributed vertically. When the upper and lower stamping dies are closed, the embossing mold of the upper stamping die can stamp and form the transition piece. The embossing mold includes a mold body 100, with two ends of the mold body 100 being a first end 101 and a second end 102, respectively. The first end 101 is used to clamp in the upper die of the stamping machine, and the end face of the second end 102 is provided with uniformly distributed protrusions 103. The cross-section of the protrusions 103 extends from near the first end 101 to... The distance from the first end 101 gradually decreases, thereby increasing the strength of the protrusion 103 stamping the adapter piece. At the same time, a positioning part 104 is provided on the side of the mold body 100. The positioning part 104 can cooperate with the corresponding structure in the upper mold of the stamping machine to achieve the positioning of the embossing device. Therefore, the protrusion 103 at one end of the embossing mold in the embossing device of this application can stamp the surface of the adapter piece, thereby forming uniformly distributed grooves on the surface of the adapter piece, thereby improving the connection strength of the adapter piece and the cover plate structure after welding.

[0028] In this process, the embossing device is positioned with the upper die of the stamping machine by the positioning part 104, and then the embossing device is locked on the upper die by the locking part, thereby realizing the connection between the embossing device and the upper die of the stamping machine.

[0029] It is understandable that the positioning part 104 is a positioning groove. For example, as Figures 1 to 2 As shown, in this embodiment, the positioning part 104 is disposed on the side of the mold body 100 and is a positioning groove, that is, the upper mold of the stamping machine is provided with a corresponding protruding positioning structure, thereby realizing the positioning of the embossing device. In other embodiments, the positioning part 104 can also be a positioning boss, and a corresponding positioning groove is provided in the upper mold of the stamping machine, which can also realize the positioning of the embossing device.

[0030] It is understood that the positioning groove extends through the side of the mold body 100 along a direction perpendicular to the height of the mold. For example, as... Figures 1 to 2As shown, in this embodiment, the positioning groove penetrates the surface of the embossing device along the height direction perpendicular to the mold. That is, by horizontally inserting the embossing device into the upper mold of the stamping machine along the extension direction of the positioning groove, the embossing device is installed in the stamping machine. Then, the embossing device is locked in the upper mold by the locking member, thereby achieving locking and fixing.

[0031] It is understandable that the protrusions 103 are arranged in a rectangular pattern on the end face of the second end 102. For example, as... Figures 1 to 2 As shown, in this embodiment, the protrusions 103 are arranged in a rectangular array on the end face of the second end 102. In other embodiments, they may also be arranged in other shapes.

[0032] It is understandable that the cross-section of protrusion 103 is square. For example, as... Figures 1 to 2 As shown, in this embodiment, since the protrusion 103 is processed by wire cutting, the cross-section of the protrusion 103 is square.

[0033] It is understood that an arc-shaped concave surface 105 is provided between adjacent protrusions 103, and the arc-shaped concave surface 105 is recessed towards the first end 101. For example, as Figures 1 to 2 As shown, in this embodiment, since the protrusions 103 are processed by wire cutting, a smooth transition arc-shaped concave surface 105 is naturally formed between adjacent protrusions 103.

[0034] It is understood that the mold body 100 includes an upper portion 110 connecting the first end 101 and a lower portion 120 connecting the second end 102 along the height direction, and the cross-sectional area of ​​the upper portion 110 is larger than the cross-sectional area of ​​the lower portion 120. For example, as... Figures 1 to 2 As shown, in this embodiment, the upper part 110 of the mold body 100 near the first end 101 is used to connect to the upper mold of the stamping machine, and the lower part 120 near the second end 102 is used to stamp the adapter piece. Therefore, the outer periphery of the upper part 110 is larger than that of the lower part 120, thereby improving the strength of the connection. At the same time, the size of the lower part 120 is sufficient to stamp the adapter piece, saving material.

[0035] It is understood that a transition section 130 is provided between the upper part 110 and the lower part 120, and the cross-sectional area of ​​the transition section 130 gradually decreases from the upper part 110 to the lower part 120. For example, as Figures 1 to 2 As shown, in this embodiment, the upper part 110 and the lower part 120 of the embossing device are connected by a transition part 130. The cross-sectional area of ​​the transition part 130 gradually decreases from the end near the upper part 110 to the end near the lower part 120, thereby improving the strength of the connection between the upper part 110 and the lower part 120.

[0036] Understandably, the sides of the transition section 130 are smooth curved surfaces. For example, as... Figures 1 to 2As shown, in this embodiment, the side of the transition portion 130 is a curved surface; in other embodiments, it may also be an inclined surface.

[0037] It is understandable that the end face of protrusion 103 away from the first end 101 is a plane. For example, as... Figures 1 to 2 As shown, in this embodiment, the end face of the protrusion 103 away from the first end 101 is a plane, thereby preventing the end of the protrusion 103 from injuring the worker's hand.

[0038] According to the embossing method in the second aspect of the present invention, the embossing device in the first aspect of the present invention is used to stamp and form the surface of the adapter piece by means of the embossing mold in the embossing device, thereby forming uniformly arranged grooves on the surface of the adapter piece. In this way, when the adapter piece and the battery cover structure are welded, the connection strength between the adapter piece and the cover structure can be improved, thereby improving the effectiveness of the battery.

[0039] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
