[0026] The die 1200 includes: a first die 1210, a second die 1220, a third die 1230, a fourth die 1240, a fifth die 1250, a sixth die 1260, a seventh die 1270, an eighth die 1280, and a ninth die 1290.

[0027] The motion conversion mechanism 1400 includes: a conversion base 1410, a slide 1420, a conversion block 1430, and a roller 1440. The conversion base 1410 is fixedly connected to the lower mold base 900 by bolts. The slide 1420 is provided on the side of the conversion base 1410. The slide 1420 is connected to the roller 1440. The roller 1440 is connected to the conversion block 1430 through a shaft. The conversion block 1430 is connected to the material.

[0028] The working principle of this utility model is as follows: The upper die holder 100 is connected to the stamping equipment. The upper die holder 100 drives the fixed structure on it to stamp the material from top to bottom. The material is mounted on the lower die fixing plate 1000 from one side, awaiting processing. The upper die holder 100 moves along the guide post 1100 via the guide sleeve 500. During this process, the positioning post 700, in conjunction with the positioning groove 1300, plays a positioning role. The rigid pusher 600 drives the motion conversion mechanism 1400, allowing the material to enter the next station for continuous stamping and production.

[0029] In the above process, the punch 400 and die 1200 change the shape of the material during extrusion according to their respective shapes, thereby completing the manufacturing of the snap-on bracket product. First, the complete material enters the first station, where the first punch 410 and T-shaped punch 420 work: the first punch 410 cuts off the upper end of the material, controlling its height, and simultaneously acts as a baffle; the T-shaped punch 420 cuts off the lower end of the material, controlling its height and controlling the lateral width, and cutting out sufficient space to clearly distinguish the first and second sets of products. Simultaneously, the first die 1210 also cooperates in stamping and cutting. The fixing block 1211 on the first die 1210 acts as a baffle to fix the material, and the small hole on the first die 1210, in conjunction with the positioning pin 700, drills positioning holes on the first set of products, thus cooperating with the subsequent positioning pin 700. In the second station, the square holes of the second punch 430 and the second die 1220 work together to drill fixing holes on the products. In the third station, the third punch 460, in conjunction with the groove of the third die 1230, stamps two sets of products. Through simultaneous work in the subsequent fourth station, the top of the product is punched into a suitable shape. The U-shaped punch 440 and the cylindrical punch 450, in conjunction with the positioning hole and U-shaped groove on the third die 1230, begin punching the internal structure on the product, specifically punching a hole and a U-shaped groove with symmetrical angles. The fourth station essentially completes the processing of the entire top part of the product by the third punch 460 and the third die 1230 in the previous station. In the fifth station, the fourth punch 470, in conjunction with the fourth die 1240 and the fifth die 1250, punches and folds the left and right ends of the product upwards, while simultaneously using the U-shaped groove to fold the middle of the product upwards. In the sixth station, the upper die fixing plate 200, with its hollow structure, works with the sixth die 1260 to support the bottom of the product, achieving a slight upward folding of the left and right sides of the product during the stamping process. At the seventh station, the fifth punch 480, in conjunction with the seventh die 1270, holds the bottom of the product against the wall. Similar to the previous stations, it further stamps the product, causing the slightly folded edges on both sides to fold upwards. At the eighth station, the sixth punch 490, in conjunction with the eighth die 1280, holds the bottom of the product against the wall, repeating the operation similar to the previous two stations, causing both sides of the product to fold completely, with the folded edges perpendicular to the bottom. At the ninth station, the S-shaped punch 4100, in conjunction with the ninth die 1290, avoids the folded edges on the U-shaped groove, and then punches and breaks off the connecting edge at the top of the product, completing the product output. The remaining scrap material is then passed downwards, and the fixing holes on the material are then fixed to the buckles on the conversion block 1430.

[0030] Finally, the entire material can move sequentially across the workstations via the rigid pusher 600 and the motion conversion mechanism 1400. The principle is as follows: during each downward press, the rigid pusher 600 contacts the roller 1440. After pressing, it depresses the roller 1440, causing it to rotate. The roller 1440, via its shaft, drives the conversion block 1430 to move within the slide groove 1420. The conversion block 1430 is connected to the material via a fastener, thus moving the material to the next workstation. Therefore, the first round of punching must be completed manually. After the first round, the fixing hole and fastener are secured, allowing for continuous punching until the entire material is used.

[0031] Compared with traditional technology, this invention enables continuous punching with a single tooling, significantly improving production efficiency.

[0032] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
