Description
Technical Field
[0001] This utility model relates to the field of metal stamping technology, and in particular to stamping dies and stamping devices for metal stamping. Background Technology
[0002] Metal stamping is a manufacturing process that uses dies and presses to apply pressure to sheet metal, causing it to separate or plastically deform, thereby obtaining parts with the desired shape, size, and performance. This technology is widely used in the automotive, electronics, home appliance, and aerospace industries, and is characterized by high efficiency, low cost, and suitability for mass production.
[0003] A search revealed Chinese patent publication number CN202320971355.X, which includes a mounting plate and a top plate. Connecting rods are fixedly connected to the four corners of the top of the mounting plate, and the four inner corners of the top plate are respectively fixedly connected to the outside of the four connecting rods. A hydraulic cylinder is fixedly connected to the top of the top plate, and a disassembly and installation structure is fixedly connected to the bottom of the hydraulic cylinder. The output end of the hydraulic cylinder is connected to a clamping mechanism. The disassembly and installation structure includes a connecting block, and two mounting cylinders are fixedly connected to the front side of the connecting block. This invention enables rapid replacement of the stamping die, thereby reducing the time required for die replacement and improving production efficiency. It also achieves automatic material clamping, eliminating the need for manual clamping and saving time, thus further improving production efficiency. However, the existing stamping module in this application requires removing the workpiece from the mold after stamping a product before continuing processing, resulting in slow efficiency and making it inconvenient for users to process large quantities of workpieces.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention features a rotating pressure plate symmetrically connected to one side of an upper mold. One side of the pressure plate has an arc-shaped edge at its bottom, while the other side has a stamping edge. When the hydraulic telescopic rod drives the upper mold downwards, the two rotating pressure plates rotate via the arc-shaped edges. A stamping groove is provided on both sides of the lower mold, its size matching the stamping edge. Simultaneously, the other stamping edge engages with the corresponding stamping groove in the lower mold, allowing for simultaneous stamping of both sides of the symmetrical metal part. A connecting block is provided between the rotating pressure plate and one side of the upper mold, and a tension spring is installed between them. The tension spring's contraction resets the rotating pressure plate. A limit block is provided on the other side of the rotating pressure plate, and a corresponding limit baffle is provided on one side of the upper mold. The limit baffle, through the limit block, limits the rotation of the rotating pressure plate, preventing excessive rotation when the tension spring resets it. A guide slope on one side of the lower mold facilitates the removal of the stamped workpiece.
[0016] This invention features a conveying device with a guide groove at its top. Two sets of drive rollers are symmetrically arranged at the top of the guide groove. The guide groove corresponds to the size of the metal part. A drive motor on one side of each drive roller drives the metal part within the guide groove. A pusher plate is movably mounted on one side of the guide groove, with an electric push rod on one side of the pusher plate. The pusher plate is positioned within the guide groove on the lower mold side. The electric push rod drives the pusher plate to guide the metal part from the guide groove onto the upper mold, achieving automatic feeding and improving the device's efficiency.

[0039] As a further limitation of this technical solution, the top of the conveying device 4 is provided with a guide groove 401, and the top of the guide groove 401 is provided with a drive roller 402. There are two sets of drive rollers 402, which are symmetrically arranged. The guide groove 401 is corresponding to the size of the metal part 10. The metal part 10 in the guide groove 401 is conveyed by a drive motor corresponding to one side of the drive roller 402 (the drive roller 402 is driven by a motor, which is a conventional and known technology in this field, so it is not described in detail). In conjunction with the push device 11, a push plate 1102 is movably arranged on one side of the guide groove 401. An electric push rod 1101 is arranged on one side of the push plate 1102.

The limiting blocks 903 on both sides of the upper mold 8 limit the metal part 10. The hydraulic cylinder 6 drives the hydraulic telescopic rod 7 to push the upper mold 8 down. The rotating pressure plates 801 on both sides rotate through the arc edge. As the pressure plate 801 rotates, the other stamping edge of the rotating pressure plate 801 is engaged in the corresponding stamping groove 902 of the lower mold 9. Both sides of the symmetrical metal parts 10 are stamped simultaneously. After the stamping is completed, the limiting blocks 903 on both sides of the lower mold 9 lose their limiting effect on the stamped metal parts 10. The hydraulic telescopic rod 7 drives the upper mold 8 to rise. The tension spring 803 retracts and drives the rotating pressure plate 801 to reset. The drive roller 402 drives the next metal part 10 to be guided to one side of the push plate 1102.
