[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube and profile materials, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size.

[0003] Many existing lighting products typically use metal casings for aesthetics and heat dissipation. However, this metal casing significantly interferes with and hinders antenna signal transmission, usually requiring notches in the metal casing to allow the antenna to receive and transmit signals. But antenna installation is limited by the size and location of these notches in the metal casing, which often affects the antenna's wireless transmission performance and, to some extent, complicates the internal structure of the lighting fixture, making manufacturing difficult.

[0004] Therefore, there is an urgent need for a stamping die and processing equipment to solve the above problems. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] This utility model provides a stamping die, such as Figure 1 As shown, the stamping die includes a positioning seat 1 and a stamping cutter 2.

[0042] The positioning base 1 has a punching die hole 11, allowing the material to be punched 100 to be fitted and positioned on the positioning base 1, ensuring the stability of the material to be punched 100 during the punching process. The side wall of the material to be punched 100 covers the punching die hole 11, and the punching cutter 2 is positioned directly opposite the punching die hole 11. The punching cutter 2 can move relative to the positioning base 1 to extend into or retract from the punching die hole 11, and cut out the communication antenna structure 101 from the material to be punched 100. In this embodiment, the material to be punched 100 is the metal shell of a lamp, specifically a metal heat sink for the lamp, such as an aluminum cup heat sink. This punching die can directly punch out the antenna structure on the metal shell of the lamp, ensuring communication performance, effectively saving structural space of the lamp, simplifying the assembly method, and improving production efficiency.

[0043] Specifically, such as Figures 1-4 As shown, a first support portion 12 and a second support portion 13 are provided inside the die hole 11. The first support portion 12 and the second support portion 13 are arranged circumferentially around the die hole 11, and the free ends of the first support portion 12 and the second support portion 13 extend into the die hole 11 and are spaced apart from each other. During the process of the stamping cutter 2 extending into the die hole 11, the stamping cutter 2 can stamp and cut off the part of the side wall of the material to be stamped 100 that does not abut against the first support portion 12 and the second support portion 13, retaining the part that abuts against the first support portion 12 and the second support portion 13. The retained part is the cut and formed communication antenna structure 101. By adjusting the structure of the first support portion 12 and the second support portion 13, the specific shape of the stamped communication antenna structure 101 can be changed, and a wire can be connected subsequently to realize the communication function.

[0044] Optionally, the line connecting the free end of the first support portion 12 and the free end of the second support portion 13 is parallel to the central axis of the material 100 to be stamped. In this embodiment, the first support portion 12 has an L-shaped structure. This design facilitates processing and manufacturing, and results in a more aesthetically pleasing metal casing for the stamped lamp.

[0045] To be more specific, continue to refer to Figure 2 , Figure 3 and Figure 5The stamping cutter 2 has a first forming groove 21 and a second forming groove 22 at its cutting edge. The first forming groove 21 and the first support portion 12 are positioned opposite each other, and the second forming groove 22 and the second support portion 13 are positioned opposite each other. When the stamping cutter 2 extends into the die hole 11, the first forming groove 21 and the second forming groove 22 can respectively cut out the communication antenna structure 101 at the contact point between the side wall of the material to be stamped 100 and the first support portion 12 and the second support portion 13. That is to say, the first forming groove 21 and the second forming groove 22 of the stamping cutter 2 cooperate with the first support portion 12 and the second support portion 13 respectively, so that the solid part of the cutting edge of the stamping cutter 2 can cut out the communication antenna structure 101 from the side wall of the material to be stamped 100.

[0046] More specifically, a cutting portion 23 is provided around the opening of the first forming groove 21, the opening of the second forming groove 22, and the end face of the cutting edge. The cutting portion 23 protrudes from the end face of the cutting edge. During the movement of the stamping cutter 2 toward the material to be stamped 100, the cutting portion 23 first contacts the side wall of the material to be stamped 100, achieving initial positioning on the one hand, and serving as a cutting edge on the other hand, to cut off the portion of the side wall of the material to be stamped 100 that does not abut against the first support portion 12 and the second support portion 13.

[0047] Preferably, in this embodiment, a cutting bevel is formed on the side of the end face of the cutting portion 23 away from the blade tip. The cutting bevel of the cutting portion 23 located around the first forming groove 21 is inclined towards the groove opening of the first forming groove 21, the cutting bevel of the cutting portion 23 located around the second forming groove 22 is inclined towards the groove opening of the second forming groove 22, and the cutting bevel of the cutting portion 23 located around the end face of the blade tip is inclined towards the outer periphery of the blade tip. With the above arrangement, cutting edges can be formed around the groove opening of the first forming groove 21, the groove opening of the second forming groove 22, and the end face of the blade tip, so that stamping and cutting can be completed quickly when the stamping tool 2 abuts against the side wall of the material 100 to be stamped.

[0048] Optionally, continue to refer to Figure 1 and Figure 2 The positioning seat 1 has a support surface 14, and a punch hole 11 is formed on the support surface 14. The support surface 14 can fit against the inner wall of the material to be punched 100, so as to support, fix and position the material to be punched 100. In this embodiment, the support surface 14 is an arc-shaped surface adapted to the inner wall of the metal shell of the lamp. When the metal shell is fitted onto the positioning seat 1, the support surface 14 fits against the inner wall of the metal shell. At the same time, a positioning boss can also be provided on the support surface 14 to cooperate with the stepped structure inside the metal shell to achieve a more accurate positioning effect.

[0049] Alternatively, the die hole 11 is formed through the positioning seat 1. With this configuration, when the stamping cutter 2 cuts off the part of the side wall of the material to be stamped 100 that does not abut against the first support 12 and the second support 13, the cut-off material can be unloaded from the other side of the positioning seat 1 without having to flip the positioning seat 1, thus saving processing time.

[0050] Furthermore, the side of the positioning seat 1 away from the support surface 14 forms a blanking surface, and the punch hole 11 penetrates the support surface 14 and the blanking surface. A blanking space is formed between the blanking surface and the inner wall of the material to be punched 100. The cut-off material can fall directly into the blanking space and then fall from the blanking space into the collection trough or other places.

[0051] It is understood that, in this embodiment, the inner surface of the cut and shaped communication antenna structure 101 also needs to be electroplated, either fully or at the solder joints, so that electrical connection wires can be soldered at the solder joints for subsequent connection and conduction with the power board.

[0052] The manufacturing and use steps of the stamping die provided in this embodiment are as follows:

[0053] The first step is drawing. Based on the product size and antenna transmission requirements, a 3D drawing of the antenna shape is created.

[0054] The second step is to manufacture the stamping die. Based on the drawn 3D drawings, the corresponding stamping die is processed. After the stamping die is completed, the process also includes deburring, trimming, and edge trimming. Among them, the stamping tool 2 is used to stamp the communication antenna structure 101 on the material to be stamped 100, and the positioning seat 1 is used to fix and position the material to be stamped 100.

[0055] The third step is electroplating. The inner surface of the stamped communication antenna structure 101 is electroplated, either all over or at the solder joints, so that electrical connection wires can be soldered at the solder joints for subsequent connection and conduction with the power board.

[0056] This embodiment also provides a processing device, which includes a base, a driving component, and the aforementioned stamping die. Specifically, the positioning seat 1 is connected to the base, and the stamping cutter 2 is connected to the output end of the driving component and moves under the drive of the driving component. In this embodiment, the driving component can be a motor or a hydraulic cylinder, etc. The stamping cutter 2 can extend into or retract from the stamping die hole 11 under the driving action of the motor and the transmission component, or the stamping cutter 2 can extend into or retract from the stamping die hole 11 under the drive of the piston of the hydraulic cylinder, thereby completing the stamping forming of the communication antenna structure 101.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
