Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically a stamping device for processing and forming aluminum alloy workpieces. Background Technology

[0002] Aluminum alloy is an alloy material composed primarily of aluminum, with appropriate amounts of other metallic elements (such as copper, magnesium, manganese, silicon, zinc, etc.). By adding different alloying elements and employing specific production processes, aluminum alloys with different properties can be obtained. They are widely used in aerospace, automobile manufacturing, architectural decoration, electronics, and many other fields. A mechanical device is specifically designed for the plastic deformation processing of aluminum alloy materials. This device applies high pressure to deform aluminum alloy sheets or profiles within a mold, thereby obtaining workpieces of the desired shape and size. Due to the excellent plasticity and lightweight properties of aluminum alloys, they are widely used in aerospace, automobile manufacturing, electronic casings, and many other fields.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219597805U) discloses an aluminum alloy stamping forming device, including a worktable, a stamping rod, and a stamping table. The stamping rod is equipped with a guide mechanism to assist in heat dissipation during stamping, and the guide mechanism is equipped with an oiling mechanism to ensure stable operation. The guide mechanism includes a piston cylinder installed inside the stamping table, with a guide rod slidably mounted inside the piston cylinder. One side of the guide rod is connected to the stamping end of the stamping rod, and the bottom of the piston cylinder has two air inlets, one inside the stamping table and the other outside. The purpose of this utility model is to provide an aluminum alloy stamping forming device that can continuously replace the hot air inside the stamping table, automatically cooling the stamping table and avoiding the need for repeated use before cooling the mold, thus saving considerable time and improving the efficiency of aluminum alloy workpiece production.

[0004] Although the aforementioned patent, through its structural design, can continuously replace the hot air inside the stamping station and automatically cool the station, avoiding the need for repeated use to cool the mold and saving considerable time, thus improving the efficiency of aluminum alloy workpiece production, there are still some areas where the stamping process is not smooth enough. This makes it difficult to correct through secondary stamping, resulting in uneven, bumpy, or poor-looking finished products. This affects product quality and aesthetics, and an uneven or irregular surface may affect the workpiece's sealing, corrosion resistance, or other performance requirements.

[0005] Therefore, this utility model provides a stamping device for processing and forming aluminum alloy workpieces to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] 1. When aluminum alloy workpieces are processed and stamped using the set pressure-bearing mechanism, uneven stamping may occur in some areas. The pressure-bearing mechanism can achieve the effect of secondary stamping.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a stamping device for processing and forming aluminum alloy workpieces, such as... Figures 1-4As shown, the stamping device for processing and forming aluminum alloy workpieces includes a top plate 1, a stamping machine 2 fixedly connected to the middle of the bottom of the top plate 1, a pressure bearing mechanism fixedly connected to the bottom of the stamping machine 2, and a buffer mechanism fixedly connected to one side of the upper surface of the top plate 1.

[0028] The pressure-bearing mechanism includes a housing 3, the upper surface of which is fixedly connected to the bottom of the stamping machine 2. An internal gear ring 4 is rotatably connected inside the housing 3. A gear disk 5 meshes with the inner side wall of the internal gear ring 4. A micro drive motor 6 is fixedly connected to the middle of the upper surface of the gear disk 5. A plug rod 7 is fixedly connected to one side of the upper surface of the internal gear ring 4. A weight block 8 is plugged into the outer surface of the plug rod 7. When stamping aluminum alloy workpieces, uneven stamping may occur in some areas. The pressure-bearing mechanism can achieve the effect of secondary stamping. When the micro drive motor 6 is started, it drives the gear disk 5 to rotate. When the gear disk 5 rotates, it drives the internal gear ring 4 to rotate. When the internal gear ring 4 rotates, it drives the plug rod 7 and the weight block 8 to move. When the weight block 8 moves to the uneven position, the part will be stamped again due to the pressure of the weight.

[0029] The cushioning mechanism includes an air pump 9. The outer surface of the air pump 9 is fixedly connected to one side of the upper surface of the top plate 1. The output end of the air pump 9 is fixedly connected to a connecting pipe 10. One end of the connecting pipe 10 is fixedly connected to an airbag 11. When the air pump 9 is started, the air pump 9 inflates in the connecting pipe 10. The gas is transmitted to the airbag 11, inflating the airbag 11 and increasing the cushioning effect.

[0030] A support plate 12 is fixedly connected to the middle of the outer shell 3, and a heating ring 13 is fixedly connected to the bottom of the outer shell 3. The heating ring 13 is activated during stamping, and the heating ring 13 can heat the material through the stamping plate 14 to improve the quality during stamping.

[0031] A stamping plate 14 is fixedly connected to the bottom of the heating ring 13. The surface of the stamping plate 14 is provided with heat dissipation grooves. The upper surface of the stamping plate 14 is connected to the bottom of the airbag 11. It will not suddenly drop when the stamping machine 2 is stamping. The material of the airbag 11 is reinforced with thickness and toughness, so it will not break due to the stamping action. It can enhance the cushioning effect during stamping.

[0032] Support rods 15 are fixedly connected to all four sides of the bottom of the top plate 1. One end of the support rod 15 is fixedly connected to the bottom plate 16. A stamping block is fixedly connected to the upper surface of the bottom plate 16. The bottom plate 16 serves to bear pressure. The aluminum alloy workpiece is placed on the bottom plate 16 and pressure is stamped on the bottom plate 16.

[0033] A slider 17 is fixedly connected to the surface of the stamping plate 14, and a groove is provided on the surface of the outer shell 3. The slider 17 is slidably connected to the inside of the groove. When stamping, the stamping plate 14 is pressed into the inside of the outer shell 3 by the slider 17, which plays the role of stretching and pressing, and facilitates buffering the stamping pressure.

[0034] A vertical rod 18 is fixedly connected to the middle of the stamping machine 2. A compression spring 19 is sleeved on the outer surface of the vertical rod 18. When the stamping machine 2 is processing stamping, the vertical rod 18 and the compression spring 19 can play a slight buffering effect during stamping.

[0035] Specifically, when stamping aluminum alloy workpieces, the material is placed on the base plate 16, and the stamping machine 2 is started. During stamping, the stamping machine 2, through the upright 18 and the compression spring 19, provides a slight buffering effect. Then, the air pump 9 is started, and air is pumped into the connecting pipe 10. The air is then transmitted to the air bag 11, inflating it. The air bag 11 will not suddenly drop during stamping by the stamping machine 2, and the material of the air bag 11 is reinforced with thickness and toughness, so it will not break due to the stamping action. This enhances the buffering effect during stamping. The buffering mechanism can control the release speed of the stamping force, preventing sudden deformation or cracking of the material during stamping, and improving the forming quality and surface finish of the workpiece. Subsequently, the stamping machine 2 is started. Heating ring 13 heats the material through stamping plate 14, improving the quality during stamping. If unevenness occurs in some areas after stamping, micro drive motor 6 is activated, driving gear disk 5 to rotate. When gear disk 5 rotates, it drives internal gear ring 4 to rotate. When internal gear ring 4 rotates, it drives plug rod 7 and weight block 8 to move. When weight block 8 moves to the uneven position, it will stamp the part again due to the pressure of the weight. Through secondary stamping, the bulges, depressions or deformations that occurred in the first stamping can be effectively eliminated, making the surface of the workpiece smoother, thereby improving the overall quality of the finished product. Flat and uniform stamping can reduce stress concentration and enhance the overall strength and durability of the workpiece.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
