DETAILED DESCRIPTION

[0021] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1 As shown, the present invention provides an aluminum alloy stamping part for use in a pedal. It includes a main plate 1, a limiting portion 2, and an ear portion 3. The main plate 1 has a centerline, a plurality of punching holes 11, and a plate body 12 located on both sides of the centerline. The plate body 12 serves as a support and connection. The ear portion 3 is connected to the side of the plate body 12 away from the centerline, and the ear portion 3 has an accommodating space 31. The limiting portion 2 is disposed in the accommodating space 31 and connected to the plate body 12, serving to fix and restrict the position. Both plates 12 are provided with a plurality of punching holes 11, and the plurality of punching holes 11 are arranged symmetrically about the centerline. The plurality of punching holes 11 located on the same plate body 12 are spaced apart along the length of the plate body 12.

[0023] This embodiment increases the overall stability of the stamping part through the ear 3 and the limit part 2, and during use, the ear 3 and the limit part 2 can also serve as a limiting structure; in addition, the multiple punching holes 11 are symmetrically arranged with the center line as the axis, which helps to balance the stress distribution during the stamping process and reduce local stress concentration, thereby reducing the risk of deformation and fracture. The multiple punching holes 11 located on the same plate body 12 are spaced apart along the length direction of the plate body 12, which can avoid excessive local stress of the material caused by too small a hole spacing, thereby preventing the aluminum alloy from breaking or deforming when punching 11 at one time.

[0024] It should be noted that the two plates of this embodiment are an integrated structure. In addition, the plates, ears and limiting parts are also an integrated structure.

[0025] like Figure 3 As shown, the main plate 1 is designed in an arc shape to increase its rigidity and prevent deformation when subjected to external forces. Compared to a flat design, the arc-shaped structure can better disperse stress, reduce localized stress concentration, and thus improve the material's resistance to deformation. Furthermore, the arc-shaped design can more evenly distribute stress across the main plate 1, preventing material fracture or deformation caused by excessive localized stress, thereby improving the overall stability and reliability of the stamped part.

[0026] like Figure 2 As shown, the ear portion 3 includes a first end portion 32, a second end portion 33 and a third end portion 34. The first end portion 32, the second end portion 33 and the third end portion 34 are connected in sequence to define an accommodating space 31, providing a stable installation position for the limiting portion 2, and the end of the first end portion 32 away from the second end portion 33 is connected to the plate body 12, and the end of the third end portion 34 away from the second end portion 33 is connected to the plate body 12, and the connection between the second end portion 33 and the first end portion 32 and the third end portion 34 is a smooth connection.

[0027] Based on the above structure, the first end 32 and the third end 34 are respectively connected to the plate body 12 and, together with the second end 33, form a stable semi-enclosed structure that effectively resists external impact and pressure. Furthermore, the connection between the second end 33 and the first and third ends 32, 34 is a smooth transition, avoiding stress concentration caused by sharp edges. This smooth connection evenly distributes stress, reducing the risk of localized excessive stress, thereby improving the durability and reliability of the ear 3.

[0028] In some embodiments, the extension direction of the first end 32 is perpendicular to the extension direction of the second end 33, so that the ear 3 forms a stable support structure in the vertical direction, which helps to maintain the stability of the ear 3 during the stamping process, effectively disperses stress, avoids local stress concentration, and thus reduces the risk of deformation and fracture of the ear 3 during the stamping process. The extension direction of the second end 33 and the extension direction of the third end 34 are set at an obtuse angle, so that the ear 3 also has good support in the horizontal direction. The obtuse angle setting can provide a larger contact area, better disperse stress, reduce stress concentration points, and increase the stability of the structure.

[0029] In some embodiments, the first end portion 32 has a first end face 321 facing the plate body 12, a second end face 322 facing the limiting portion 2, and a first top face 323 connected to the first end face 321 and the second end face 322. The connection between the first end face 321, the second end face 322 and the first top face 323 is chamfered.

[0030] The rounded corner structure of this embodiment can significantly reduce stress concentration. During the stamping process, sharp edges and corners can easily become points of stress concentration, causing the material to crack. By designing the connection between the first end face 321, the second end face 322 and the first top face 323 as a rounded corner, the stress can be evenly distributed, and the risk of excessive local stress can be reduced, thereby effectively avoiding the material from cracking during the stamping process. In addition, the rounded corner structure not only reduces the risk of material cracking, but also reduces the wear of the stamping die. Sharp edges and corners will increase the friction between the die and the material during the stamping process, resulting in accelerated wear on the die surface. The rounded corner structure can provide a smoother transition, reduce friction, and extend the service life of the die.

[0031] Preferably, the radius of the fillet is 0.1-0.3 mm. This range of radius can effectively disperse stress and reduce the risk of localized excessive stress, thereby effectively preventing the material from cracking during the stamping process. At the same time, the radius should not be too large to affect the compactness and aesthetics of the structure.

[0032] In some embodiments, a first inclination angle is provided between the first end face 321 and the plate body 12, which can reduce stress concentration at the connection between the first end 32 and the plate body 12, so that stress is more evenly distributed at the connection, reducing the risk of local excessive stress; a second inclination angle is provided between the second end face 322 and the plate body 12 to reduce stress concentration at the connection between the second end 33 and the plate body 12, which helps to improve the overall strength of the first end 32 and prevent cracking or deformation during the stamping process; a third inclination angle is provided between the end face of the second end 33 facing the limiting portion 2 and the plate body 12 to reduce stress concentration at the connection between the second end 33 and the plate body 12, ensuring the stability of the second end 33 during the stamping process and preventing displacement or deformation.

[0033] This embodiment forms a smooth transition surface through the structure of the first inclination angle, the second inclination angle and the third inclination angle to reduce the friction between the material and the mold during the stamping process, reduce the wear of the mold, and extend the service life of the mold. At the same time, the smooth transition surface can guide the material to flow more smoothly during the stamping process, reduce the accumulation and blockage of the material in the mold, and improve the molding accuracy and consistency.

[0034] In some embodiments, the third end portion 34 has a third end face 341 facing the plate body 12, a fourth end face 342 facing the limiting portion 2, and a second top face 343 connected to the third end face 341 and the fourth end face 342. The connection between the third end face 341, the fourth end face 342 and the second top face 343 is chamfered.

[0035] The rounded corner structure of this embodiment can significantly reduce stress concentration. During the stamping process, sharp edges and corners can easily become points of stress concentration, causing the material to crack. By designing the connection between the third end face 341, the fourth end face 342 and the second top face 343 as a rounded corner, the stress can be evenly distributed, and the risk of excessive local stress can be reduced, thereby effectively avoiding the material from cracking during the stamping process. In addition, the rounded corner structure not only reduces the risk of material cracking, but also reduces the wear of the stamping die. Sharp edges and corners will increase the friction between the die and the material during the stamping process, resulting in accelerated wear on the die surface. The rounded corner structure can provide a smoother transition, reduce friction, and extend the service life of the die.

[0036] Preferably, the radius of the fillet is 0.1-0.3 mm. This range of radius can effectively disperse stress and reduce the risk of localized excessive stress, thereby effectively preventing the material from cracking during the stamping process. At the same time, the radius should not be too large to affect the compactness and aesthetics of the structure.

[0037] In some embodiments, there is a fourth inclination angle between the third end face 341 and the plate body 12 to reduce stress concentration at the connection between the third end 34 and the plate body 12, so that the stress is more evenly distributed at the connection, reducing the risk of local excessive stress. There is a fifth inclination angle between the fourth end face 342 and the plate body 12, which can also reduce stress concentration at the connection between the fourth end and the plate body 12, help to improve the overall strength of the third end 34, and prevent cracking or deformation during the stamping process.

[0038] This embodiment utilizes the fourth and fifth angles to create a smooth transition surface, reducing friction between the material and the die during the stamping process, minimizing die wear and extending the die's service life. Furthermore, the smooth transition surface guides material flow more smoothly during the stamping process, reducing material accumulation and blockage in the die, and improving forming accuracy and consistency.

[0039] In summary, the embodiment of the present invention provides an aluminum alloy stamping part, wherein a plurality of punching holes 11 are symmetrically arranged with the center line as the axis, which helps to balance the stress distribution during the stamping process, reduce local stress concentration, and thus reduce the risk of deformation and fracture. The plurality of punching holes 11 located on the same plate body 12 are spaced apart along the length direction of the plate body 12, which can avoid excessive local stress of the material caused by too small a hole spacing, thereby preventing the aluminum alloy from breaking or deforming when punching a hole 11 once. The rounded corner structure not only reduces the risk of cracking of the material, but also reduces the wear of the stamping die.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
