Description

Technical Field

[0001] The utility model relates to the technical field related to battery box cover processing, in particular to a stamping die for an aluminum alloy battery box cover product. Background Art

[0002] New energy vehicles (NEVs) use unconventional fuels as their power source (or use conventional fuels with new onboard power units), integrating advanced technologies in vehicle power control and drive to create vehicles with advanced technical principles, new technologies, and new structures. Electric vehicles primarily rely on electricity for energy, and the battery box is the main carrier of the NEV battery, with the battery box cover being an external structural component of the TV box.

[0003] After extensive searching, it was found that the prior art publication number is CN217595655U, which discloses a stamping die for a metal battery box cover of an electric vehicle, including a base plate, a die base connected to the center of the top of the base plate, movable grooves are provided on all four sides of the top of the die base, a limiting rod is fixedly connected to the inside of the movable groove, a movable block is movably connected to the outer surface of the limiting rod, and a movable rod is fixedly connected to the top of the movable block. The use of the movable block, the movable rod and the push-pull handle, pushing the push-pull handle, causes the movable rod to move, and then the movable block drives the movable rod to move, and the movement of the movable rod can cause the pressure plate to move, and then it can be adjusted according to the size of the metal, thereby improving the functionality of the equipment, wherein the use of the first spring can drive the pressure plate to fix the metal through the reaction force of the first spring, thereby preventing the metal from deflecting during stamping, thereby improving the quality of the equipment stamping.

[0004] Or as Figures 3-4 As shown in the figure, the existing clearance between the scrap cutter and the trimming punch is zero. Shear hardening and chipping occur when the material is sheared. Furthermore, the clearance between the scrap cutter and the upper die is too long, causing chipping to enter the die during the return stroke, resulting in product damage.

[0005] In view of the above-mentioned defects, the designer actively carried out research and innovation in order to create a stamping die for an aluminum alloy battery box cover product to make it more valuable for industrial use. Utility Model Content

[0015] As a further improvement of the present invention, the gap is 0.9-1 mm.

[0016] As a further improvement of the present invention, the matching distance between the blade on the upper die scrap cutter and the scrap cutter holder above is 0.9 to 1 mm.

[0017] By means of the above solution, the present invention has at least the following advantages:

[0018] The utility model provides a gap between the upper die waste cutter and the inner trimming punch for air avoidance treatment, thereby reducing the adverse effects of this gap on material shearing.

[0032] Example

[0033] like Figures 1 and 2 As shown,

[0034] A stamping die for an aluminum alloy battery box cover product comprises an upper die base 1 and a lower die base 2 from top to bottom, wherein a plurality of waste knife assemblies are evenly distributed around the upper die base 1 and the lower die base 2.

[0035] 1. Limiting structure between upper die base 1 and lower die base 2:

[0036] At least one limiting frame 3 is mounted on the lower die base 2, with a limiting block 4 mounted on top of the limiting frame 3. A limiting groove 5 is provided on the bottom of the upper die base 1, directly above the limiting block 4, and is compatible with the limiting block 4. The limiting block 4 is inserted upward into the limiting groove 5. The limiting block 4 and the limiting groove 5 enable the upper and lower die bases 1 and 2 to be positioned in a fixed position.

[0037] 2. The installation structure of the upper die waste knife 9 in the prior art:

[0038] like Figures 3 and 4 As shown, the existing upper die scrap cutter 9 has a zero clearance between the trimming punch 7 and the upper die scrap cutter 9. This causes shear hardening and chipping of the material during shearing. Furthermore, the contact distance between the upper die scrap cutter 9's blade 11 is too long, causing chipping to enter the die during the die return stroke, resulting in product damage.

[0039] 3. Installation structure of upper die scrap knife 9:

[0040] like Figures 5 and 6 As shown, the waste knife assembly includes a trimming punch 7, a waste knife holder 8 and an upper mold waste knife 9. The upper mold waste knife 9 is installed on the bottom side of the waste knife holder 8, and the waste knife holder 8 is installed on the bottom of the upper mold base 1. The trimming punch 7 is installed on the upper mold base 1 inside the upper mold waste knife 9.

[0041] 1) A gap 12 is provided between the upper die scrap cutter 9 and the inner trimming punch 7, and the gap 12 is 0.9 to 1 mm. This gap 12 is used for air avoidance processing to reduce the adverse effects caused by this place when shearing the material.

[0042] 2) The distance between the blade 11 of the upper die scrap knife 9 and the upper scrap knife holder 8 is 0.9 to 1 mm. By reducing the blade length of the upper die scrap knife, the probability of crushing the product during the mold return stroke is reduced.

[0043] Among them, a plurality of clamping blocks 6 are evenly distributed on the upper die base 1 outside the trimming punch 7.

[0044] Among them, a lower mold waste knife groove 10 adapted to the above-mentioned upper mold waste knife 9 is provided on the lower mold base 2 just below the upper mold waste knife 9, and the upper mold waste knife 9 contacts the lower mold waste knife groove 10 from top to bottom.

[0045] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0046] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
