Description

Technical Field

[0001] The utility model specifically relates to a hardware stamping die for preventing waste material blockage, belonging to the technical field of hardware stamping dies. Background Art

[0002] Stamping refers to a processing method in which an external force is applied to materials such as plates and pipes by a press and a die to deform or cut them to obtain the required part shape. According to the required part shape, different stamping dies need to be selected. During stamping processing, a lot of waste materials are usually generated. If these waste materials are blocked in the die, it will affect the accuracy of subsequent stamped parts. Therefore, it is necessary to clean up the waste materials generated after stamping in time. In the existing stamping dies, the waste materials usually need to be manually taken out, which is quite laborious.

[0003] For example, the publication number is: CN221086888U, a hardware stamping die for preventing waste material blockage. This utility model discloses a hardware stamping die for preventing waste material blockage, which relates to the technical field of hardware stamping dies and includes a hardware stamping die assembly. A waste material blockage prevention assembly is arranged on the side of the hardware stamping die assembly, which solves the problem that during stamping, blockage is likely to occur at the aperture and fine structures due to the generated metal chips, not only making the die unable to be used normally. It realizes that by pushing the movable long plate to drive the fixed plate, the suction fan is moved close to the lower die, and then the wind blown out by starting the suction fan passes through the air collecting hood and blows onto the lower die, which can blow off the waste chips on the surface of the lower die, avoiding the situation that the waste chips are blocked and damage the die core. And a replacement mechanism is provided, which can fix the lower die through the tightening rods on both sides of the lower die with fixing nuts, and can adjust the blowing direction of the suction fan by rotating the through rod by replacing different lower dies, and fix it with screws, or start the electric telescopic rod to drive the suction fan to move up and down.

[0004] However, during use, when the material used in production has a large density and heavy mass, the waste materials cannot be blown up by relying on wind power. At the same time, according to different processed parts, the generated waste materials are also different. When large metal waste materials are generated, the wind power cannot discharge them, which is not convenient for use. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 8 As shown, a hardware stamping die for preventing waste blockage includes an upper die 1 and a lower die 2. A lower die backing plate 3 is fixedly installed at the center of the upper surface of the lower die 2. An automatic demoulding assembly 4 is fixedly installed inside the lower die backing plate 3 to facilitate the automatic demoulding of the produced parts. At the same time, elastic force assemblies 5 for ejecting waste are symmetrically hinged on both sides inside the lower die backing plate 3 to facilitate the ejection of the waste generated after stamping. A cavity is opened at the center of the upper die 1, and a compacting assembly 6 is slidably installed inside the cavity to facilitate the continuous compaction of the material during stamping to prevent accidental deformation of the material. A ring punch 7 is fixedly installed on the lower surface of the upper die 1. The ring punch 7 corresponds to the automatic demoulding assembly 4. The compacting assembly 6 is sleeved inside the ring punch 7. The lower end of the upper die 1 is sleeved with an upper die backing plate 8. The upper die backing plate 8 corresponds to the lower die backing plate 3. The upper die backing plate 8 is sleeved outside the ring punch 7.

[0026] Such as Figures 2 - 5As shown, positioning posts 9 are fixedly installed on the upper surface of the lower die 2 in a linear array. Positioning holes 10 are linearly arrayed and penetrated through the surface of the upper die 1. The positioning holes 10 are slidably connected to the positioning posts 9, so as to ensure that the relative positions of the upper die 1 and the lower die 2 always remain consistent. At the lower end of the upper die 1, sleeves 11 are fixedly installed in a circumferential array. A sliding post 12 is slidably connected inside the sleeve 11. One end of the sliding post 12 is fixedly installed at the upper end of the upper die backing plate 8. A backing plate spring 13 is connected around the outside of the sleeve 11. The upper and lower ends of the backing plate spring 13 are respectively fixedly connected to the upper die 1 and the upper die backing plate 8, so as to ensure that the upper die backing plate 8 always fits with the lower die backing plate 3 during stamping, thereby clamping the material to prevent displacement. The automatic demoulding assembly 4 includes a demoulding spring 401. The lower end of the demoulding spring 401 is fixedly connected to the lower die backing plate 3, and the upper end of the demoulding spring 401 is fixedly connected to a demoulding block 402, so as to automatically demould the parts generated after stamping. The elastic force assembly 5 includes an electric telescopic rod 501 to provide driving force for the elastic force assembly 5. The output end of the electric telescopic rod 501 is fixedly installed with a transmission block 502. A U-shaped notch is penetrated through one side of the transmission block 502. A connecting block 503 is clamped in the U-shaped notch. The other end of the connecting block 503 is fixedly connected to a pop-up frame 504, so as to drive the connecting block 503 to move through the movement of the transmission block 502, and then drive the pop-up frame 504 to pop up through the movement of the connecting block 503, so as to pop up the waste material.

[0027] As Figures 6 - 8 shown, the compaction assembly 6 includes a cylindrical pressing head 601. The cylindrical pressing head 601 is sleeved inside the annular punch 7. At the upper end of the cylindrical pressing head 601, connecting rods 602 are fixedly installed in a circumferential array. The connecting rods 602 penetrate through the upper die 1 and extend into the cavity. The other ends of the connecting rods 602 are fixedly installed with sliding blocks 603. The sliding blocks 603 are slidably installed in the cavity. The upper end of the sliding block 603 is fixedly connected to a compaction spring 604. The other end of the compaction spring 604 is fixedly connected to the upper die 1, so as to ensure that the cylindrical pressing head 601 always compacts the material during stamping to prevent the material from moving and accidentally deforming. A sliding rod 605 is fixedly installed at the center of the sliding block 603. A connecting column 14 is fixedly installed at the center of the upper end of the upper die 1. Threaded holes are penetrated through the upper end of the connecting column 14 in a circumferential array. A sliding hole 15 is penetrated through the center of the connecting column 14. The sliding rod 605 is slidably installed in the sliding hole 15.

[0028] During use, first fixedly connect the connecting column 14 to the pressurizing device. Before stamping, the staff first place the stamping material on the lower die backing plate 3, and then start the pressurizing device to provide pressure for this die to start stamping. As the upper die 1 moves, the cylindrical punch 601, the annular punch 7, and the upper die backing plate 8 first contact the surface of the material. Subsequently, the cylindrical punch 601 firmly presses against the center position of the material, and the upper die backing plate 8 firmly compacts the periphery of the material to prevent displacement and accidental deformation of the material during stamping. Then, the annular punch 7 presses against the die-lifting block 402 and continues to move downward. Finally, the material is cut and deformed by stamping. After stamping is completed, the upper die 1 is lifted upward, and the die-lifting block 402 also bounces upward under the action of the die-lifting spring 401, ejecting the part after stamping to complete the demoulding. Subsequently, the electric telescopic rod 501 drives the transmission block 502 to move, and the transmission block 502 drives the connecting block 503 to deflect at an angle. Since the connecting block 503 is fixedly connected to the bouncing frame 504, the bouncing frame 504 also deflects at an angle along with the connecting block 503, thereby realizing the ejection of the waste material.
