[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The terms "first" or "second," etc., used in this utility model to refer to numbers or ordinal numbers are for descriptive purposes only and should not be construed as indicating relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0024] like Figure 1-5 As shown in the figure, this utility model discloses a stamping and forming die, including an upper forming punch assembly 1, a lower forming die assembly 1, and a die fixing assembly 5. The upper forming punch assembly 1 and the lower forming die assembly 2 are arranged opposite each other in the vertical direction. The upper end of the upper forming punch assembly 1 is detachably connected to the lower pressing shaft 3 of the stamping machine, while the lower forming die assembly 2 is fixed on the stamping machine platform 4 by the die fixing assembly 5. The secondary reflector is placed between the upper forming punch assembly 1 and the lower forming die assembly 2 for stamping. This design avoids the cumbersome traditional bending steps and achieves rapid one-time forming of the secondary reflector, improving work efficiency.

[0025] Furthermore, the upper forming punch component 1 includes a connecting piece 12 and a forming punch 11. The connecting piece 12 is in a "convex" shape. There is a threaded hole at the lower end of the connecting piece 12. The lower end of the connecting piece 12 is connected to the upper end of the forming punch 11 through a punch fixing screw 13, and the upper end of the connecting piece 12 is connected to the lower end of the pressing shaft 3 of the stamping machine. If the forming punch 11 needs to be replaced due to wear, damage or product design changes, just unscrew the punch fixing screw 3, and it can be easily removed and replaced with a new forming punch 11, which can not only improve stability but also increase the utilization rate of the mold.

[0026] Furthermore, the connecting piece 12 can be made of at least one of high-strength alloy steel, refined iron or cemented carbide materials to improve the wear resistance and service life of the connecting piece. The forming punch 11 can be designed with different sizes to meet the forming requirements of different secondary reflectors.

[0027] Furthermore, the connecting piece 12 and the forming punch 11 can be integrally formed during casting, making the overall structure more stable and reducing costs.

[0028] As a preferred embodiment, two groups of stabilizing holes can be provided on the protruding part of the connecting piece 12, which can be more stably connected to the lower pressing shaft 3 of the stamping machine, thus ensuring that the connecting piece will not loosen or fall off during the stamping process, causing mold damage or personal injury.

[0029] As a preferred embodiment, multiple threaded holes can be provided at the lower end of the connecting piece 12 to facilitate various connection methods with the forming punch 11, improving the reliability and flexibility of the connection.

[0030] Through the screw connection method, the stability of the upper forming die component 1 is ensured, avoiding problems such as mold damage or reduced machining accuracy caused by insecure connection; secondly, the screw connection method facilitates the disassembly and replacement of the upper forming die component 1, reducing the maintenance and replacement time and improving work efficiency.

[0031] Furthermore, the forming punch 11 and the lower end of the connecting piece 12 are of the same size, ensuring that the two can be stably and tightly connected. The forming punch 11 is provided with connection holes corresponding to the threaded holes of the connecting piece 12, and the forming punch 11 and the connecting piece 12 are connected through a punch fixing screw 13 to ensure that they will not loosen or fall off during the stamping process, improving the firmness and stability of the connection and facilitating maintenance.

[0032] Furthermore, the lower forming die component 2 includes a first cushion strip 24, a second cushion block 22, a forming die 21 and a sliding-down component 23. The first cushion strip 24 is arranged on the stamping machine platform 4, the second cushion block 22 is arranged on the first cushion strip 24, the forming die 21 is arranged on the second cushion block 22, and the forming die 21 is sleeved outside the sliding-down component 23.

[0033] The various parts of the forming die assembly 1 work together to solve the structural problems in the stamping die for the sub-reflector. The first pad 24 provides basic support and reduces the load-bearing capacity during stamping, the second pad 22 further enhances the stability of the die, the forming die 21 is used for the actual forming operation, and the lower slide block 231 ensures downward sliding and precision during the forming process. Through the interaction of these technical features, precise stamping forming of the sub-reflector can be achieved.

[0034] Furthermore, the second pad 22 is provided with a protrusion 221, which helps to enhance its structural strength and stability. The protrusion 221 is provided with a groove 222 to facilitate the placement of the spring fixing member 232 to prevent it from moving. The protrusion 221 is provided with a threaded hole to facilitate the fixing of the forming die 21 and avoid displacement or loosening during the stamping process. The number and position of the threaded holes can be adjusted according to the specific mold design requirements to ensure the best fixing effect.

[0035] Furthermore, the second pad 22 is at least one of a rectangle or a square. The second pad 22 is integrally cast from at least one of high-strength alloy steel, refined iron or hard alloy material. Alternatively, multiple components can be combined into a raised shape by welding, bolting or other methods to increase the hardness of the pad and enhance its load-bearing capacity.

[0036] Furthermore, the sliding assembly 23 includes a sliding block 231, a spring 234, and a spring fixing member 232. The spring fixing member 232 is placed in the groove 222. A fixing post 233 is provided on the spring fixing member 232. The spring 234 is sleeved on the fixing post 233. The sliding block 231 is provided with a sliding hole 235. The lower end of the sliding hole 235 passes through the upper end of the fixing post 233 and connects to the lower end of the sliding block 231.

[0037] The slider 231 can be made of high-hardness materials such as stainless steel or cast iron, with stainless steel being preferred to ensure its strength and durability. The spring 234 can be made of a material with appropriate elasticity, such as steel, to ensure that it can provide sufficient elastic force during use.

[0038] Furthermore, the forming die 21 has a square hole in the middle, which is fitted onto the outside of the sliding component 23. The inner wall of the square hole is larger than that of the sliding block 231, ensuring that the sliding block 231 can move within the hole. The forming die 21 has fixing holes corresponding to the threaded holes on the protrusion 221, ensuring that the forming die 21 can be fixed to the protrusion 221 by screws, thereby achieving a stable structure. Through the cooperation between the components, the problem of how to make the sliding block 231 move up and down in the middle of the forming die 21 is solved.

[0039] The forming die 21 is made of high-hardness precision steel, and the lower slide block 231 can be made of wear-resistant material and can be designed as a replaceable structure so that it can be replaced after wear.

[0040] The gap between the outer wall of the forming punch 11 and the inner wall of the forming die 21 is exactly the thickness of the sub-reflector plate. When the forming punch 11 moves downward to press, the sub-reflector plate moves downward under the action of pressure. At the same time, the lower slide block 231 moves downward to lock, causing the four sides of the sub-reflector plate to fold inward, and the pressing is completed in one go.

[0041] Furthermore, the upper end of the fixing post 233 is provided with an internal thread. After the lower slide block 231 is placed on the upper end of the fixing post 233, it can be fixed to the fixing post 233 with screws. This prevents the lower slide block 231 from popping out under the elastic force of the spring 234 after stamping, thus avoiding accidents.

[0042] Furthermore, the forming die 21 is provided with two sets of "Z"-shaped punch fixing blocks 25, one end of each set of punch fixing blocks 25 being fixed to both sides of the forming die 21 by screws. When the forming punch 11 moves downward, it can be accurately placed onto the forming die 21. High-strength steel can be used to make the fixing parts to improve their durability and stability.

[0043] Furthermore, the forming die 21 is also provided with a blanking fixing part 26, which is located on the outside of the square hole to prevent the sub-reflector from moving or shifting during the stamping process, thereby ensuring the accuracy, quality and consistency of the stamping.

[0044] Two sets of blanking fixing parts 26 are preferably selected and are set at intervals on the outside of the square hole. One end of the blanking fixing part 26 is pressed into the hole on the forming die 21.

[0045] The blanking fastener 26 can be at least one of square, rectangular or cylindrical. The blanking fastener 26 can be made of high-strength metal material, preferably steel, to ensure that it is not easily deformed or damaged during the stamping process.

[0046] Furthermore, the die fixing assembly includes a fixing plate 5, a die fixing screw 7, and a fixing pad 6. The fixing pad 6 is placed on the press platform 4, and the fixing plate 5 is set on the fixing pad 6 and the second pad 22. The die fixing screw 7 passes through the fixing plate 5 from under the press platform 4 and fixes the lower die assembly 2 through the screw.

[0047] Furthermore, the fixing block 6 is provided at the same height as the second block 22, which makes it easier for the fixing plate 5 to hold the fixing block 6 and the second block 22 flat and press them together to maintain level and force, and can better fix the second block 22 to prevent it from moving, thereby ensuring the accuracy and stability of the stamping process.

[0048] The fixing plate 5, the die fixing screw 7, and the fixing pad 6 can all be made of at least one of steel, iron, and high-hardness metal in one piece. The fixing plate 5 and the fixing pad 6 can be formed by casting or forging. A set of fixing holes is provided in the middle of the fixing plate.

[0049] Compared with existing technologies, the technical solution of this application improves the stability and forming accuracy of the mold through the cooperation of various parts, and solves the problem that traditional edge folding requires four steps to fold one edge at a time, thereby improving production efficiency and product consistency.

[0050] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
