Description

Technical Field

[0001] This utility model relates to the field of shell stamping technology for electric vehicle production, and in particular to a shell stamping device for electric vehicle production. Background Technology

[0002] The shell stamping device for electric vehicle production is a core piece of equipment in the manufacturing of new energy vehicles. Its core function is to process metal sheets (such as aluminum alloy and high-strength steel) into electric vehicle shell parts through the synergistic action of the press and the mold. However, when installing the upper die, the traditional stamping device requires manual visual alignment of the die and the fixed plate, and the position adjustment relies on the operator's experience, which leads to defects such as asymmetrical flanging and stretching wrinkling in the stamped parts.

[0003] Therefore, those skilled in the art have provided a housing stamping apparatus for electric vehicle production to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a shell stamping device for electric vehicle production. When installing the lower die, the pull plates around the second fixing plate are pulled, and the insert plate disengages from the upper and lower slots. After the new lower die is in place, the pull plates are released, the return spring rebounds, and the insert plate snaps into the slot, ensuring that the die is quickly and accurately positioned, avoiding manual positioning deviations, improving installation efficiency and accuracy, and laying a solid foundation for stamping work.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A shell stamping device for electric vehicle production includes an upper fixed plate and a lower fixed plate. An upper pressing component is provided at the lower end of the upper fixed plate, and a lower pressing component is provided at the upper end of the lower fixed plate. The upper pressing component includes a first fixed plate, and the lower pressing component includes a second fixed plate. An upper pressing die is engaged with the inner wall of the first fixed plate, and a lower pressing die is engaged with the inner wall of the second fixed plate.

[0007] The first fixing plate and the second fixing plate are provided with snap-fit ​​components around their perimeter. Each snap-fit ​​component includes a pull plate. An insert plate is fixedly connected to one end of the pull plate near the center of the first fixing plate. A return spring is fixedly connected to one end of both sides of the pull plate near the center of the first fixing plate. An upper snap-fit ​​groove is provided around the perimeter of the first fixing plate, and a lower snap-fit ​​groove is provided around the perimeter of the lower pressing mold.

[0008] With the above technical solution, when installing the upper pressing die, pulling the pull plates around the first fixed plate moves the insert plate accordingly. When the die is placed in, releasing the pull plates causes the return spring to spring back, driving the insert plate to insert into the upper slot of the first fixed plate, quickly completing the initial positioning, improving installation efficiency, and avoiding stamping errors caused by manual positioning deviations. After positioning, rotating the fastening screw fixes one end to the threaded connection between the first fixed plate and the inner wall of the upper pressing die, providing a stable and reliable fastening force for the upper pressing die, firmly fixing it to the first fixed plate. During stamping operations, this prevents the upper pressing die from loosening or displacement due to strong stamping forces, effectively ensuring the stability and continuity of stamping work, and improving product stamping quality and production efficiency.

[0009] Furthermore, a hydraulic cylinder is fixedly connected to the middle of the upper surface of the upper fixed plate, the output end of the hydraulic cylinder passes through the upper fixed plate and is fixedly connected to the upper end of the first fixed plate, and the upper surface of the lower fixed plate is fixedly connected to the lower end of the second fixed plate.

[0010] Through the above technical solution, the hydraulic cylinder directly drives the first fixed plate, making the power transmission more direct and efficient, avoiding energy loss in the intermediate transmission structure. At the same time, the rigid connection between the lower fixed plate and the second fixed plate ensures stability during the stamping process.

[0011] Furthermore, fastening screws are provided on both sides of the front and rear ends of the first fixing plate, and the outer end of the fastening screw near the center of the first fixing plate is threaded to the inner wall of the first fixing plate and the upper pressing mold.

[0012] The above technical solution provides uniform locking force through symmetrically distributed fastening screws, ensuring that the upper die does not shift during high-speed stamping.

[0013] Furthermore, the end of the reset spring away from the pull plate is fixedly connected to the outer wall of the corresponding first fixing plate and second fixing plate, and the end of the insert plate away from the pull plate passes through the corresponding first fixing plate and second fixing plate and engages with the upper and lower slots;

[0014] The above technical solution utilizes the elastic potential energy of the reset spring to drive the insert plate to automatically engage, achieving tool-free and rapid positioning of the mold and avoiding visual deviations or operational errors during manual positioning.

[0015] Furthermore, support columns are fixedly connected to the four corners of the lower surface of the upper fixing plate, and the lower end of the support columns is fixedly connected to the upper end of the lower fixing plate.

[0016] Through the above technical solution, the four support columns form a rectangular stable structure, which effectively resists the lateral force during stamping.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model proposes a shell stamping device for electric vehicle production. When installing the upper die, pulling the pull plates around the first fixed plate moves the insert plate accordingly. When the die is placed in, releasing the pull plates causes the return spring to spring back, driving the insert plate to insert into the upper slot of the first fixed plate, quickly completing the initial positioning, improving installation efficiency, and avoiding stamping errors caused by manual positioning deviations. After positioning, rotating the fastening screw fixes one end to the first fixed plate and the inner wall of the upper die, providing a stable and reliable fastening force for the upper die and firmly fixing it to the first fixed plate. During stamping operations, this prevents the upper die from loosening or displacement due to strong stamping force, effectively ensuring the stability and continuity of stamping work, and improving product stamping quality and production efficiency.

[0019] 2. This utility model proposes a shell stamping device for electric vehicle production. When installing the lower die, the pull plates around the second fixing plate are pulled, and the insert plate disengages from the upper and lower slots. After the new lower die is in place, the pull plates are released, the return spring rebounds, and the insert plate snaps into the slot, ensuring that the die is quickly and accurately positioned, avoiding manual positioning deviations, improving installation efficiency and accuracy, and laying a solid foundation for stamping work. Compared with traditional methods, the snap-fit ​​component is easy to operate. The operator only needs to pull and release the pull plates to complete the positioning and fixing, which saves time, reduces the probability of human error, improves product stamping quality and production efficiency, and helps to produce electric vehicle shells efficiently and with high quality.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-6 One specific embodiment provided by this utility model:

[0035] A shell stamping device for electric vehicle production includes an upper fixed plate 1 and a lower fixed plate 2. An upper pressing component 3 is provided at the lower end of the upper fixed plate 1, and a lower pressing component 4 is provided at the upper end of the lower fixed plate 2. The upper pressing component 3 includes a first fixed plate 301, and the lower pressing component 4 includes a second fixed plate 401. An upper pressing die 302 is engaged with the inner wall of the first fixed plate 301, and a lower pressing die 402 is engaged with the inner wall of the second fixed plate 401.

[0036] The first fixing plate 301 and the second fixing plate 401 are provided with snap-fit ​​components 8 around their perimeter. The snap-fit ​​components 8 include pull plates 801. One end of the pull plate 801 near the center of the first fixing plate 301 is fixedly connected to an insert plate 802. Both sides of the pull plate 801 near the center of the first fixing plate 301 are fixedly connected to a return spring 803. The first fixing plate 301 is provided with an upper snap-fit ​​groove 10 around its perimeter, and the lower pressing mold 402 is provided with a lower snap-fit ​​groove 9 around its perimeter.

[0037] When installing the upper die 302, pull the pull plates 801 around the first fixed plate 301, and the insert plate 802 moves accordingly. When the die is placed in, release the pull plates 801, the return spring 803 rebounds, and the insert plate 802 is inserted into the upper slot 10 of the first fixed plate 301, quickly completing the initial positioning, improving installation efficiency, and avoiding stamping errors caused by manual positioning deviations. After positioning is completed, rotate the fastening screw 303, one end of which is threaded to the inner wall of the first fixed plate 301 and the upper die 302, providing a stable and reliable fastening force for the upper die 302, firmly fixing it to the first fixed plate 301. During stamping operations, this prevents the upper die 302 from loosening or shifting due to strong stamping force, effectively ensuring the stability and continuity of stamping work, and improving product stamping quality and production efficiency.

[0038] A hydraulic cylinder 5 is fixedly connected to the middle of the upper surface of the upper fixed plate 1. The output end of the hydraulic cylinder 5 passes through the upper fixed plate 1 and is fixedly connected to the upper end of the first fixed plate 301. The upper surface of the lower fixed plate 2 is fixedly connected to the lower end of the second fixed plate 401. The hydraulic cylinder 5 directly drives the first fixed plate 301, making the power transmission more direct and efficient, avoiding energy loss in the intermediate transmission structure. At the same time, the rigid connection between the lower fixed plate 2 and the second fixed plate 401 ensures stability during the stamping process.

[0039] Fastening screws 303 are provided on both sides of the front and rear ends of the first fixing plate 301. The end of the outer wall of the fastening screw 303 near the center of the first fixing plate 301 is threaded to the inner wall of the first fixing plate 301 and the upper pressing die 302. The symmetrically distributed fastening screws 303 provide uniform locking force to ensure that the upper pressing die 302 does not shift during high-speed stamping.

[0040] The end of the return spring 803 away from the pull plate 801 is fixedly connected to the outer wall of the corresponding first fixed plate 301 and second fixed plate 401. The end of the insert plate 802 away from the pull plate 801 passes through the corresponding first fixed plate 301 and second fixed plate 401 and engages with the upper slot 10 and lower slot 9. The elastic potential energy of the return spring 803 drives the insert plate 802 to automatically engage, realizing tool-free rapid positioning of the mold and avoiding visual deviation or operational errors during manual positioning. Support columns 6 are fixedly connected to the four corners of the lower surface of the upper fixed plate 1. The lower end of the support column 6 is fixedly connected to the upper end of the lower fixed plate 2. The four support columns 6 form a rectangular stable structure, effectively resisting the lateral force during stamping.

[0041] Working principle: The external controller starts the hydraulic cylinder 5, which drives the first fixed plate 301 to move the upper pressing die 302 downward. After the upper pressing die 302 and the lower pressing die 402 are precisely aligned and pressed together, the shell is stamped and formed. The hydraulic cylinder 5 retracts, and the upper pressing die 302 returns to its initial position, ready for the next stamping. When the upper pressing die 302 is changed, the pull plates 801 around the first fixed plate 301 are pulled outward, the return spring 803 is compressed, the insert plate 802 is removed from the upper slot 10, and the fastening screw 3 is rotated. 03. Release the threaded fixation between the upper pressing mold 302 and the first fixing plate 301, remove the old mold, put in the new mold, and then loosen the pull plate 801. The insert plate 802 will automatically snap into the upper slot 10 under the action of the spring. Finally, tighten the fastening screw 303. When replacing the lower pressing mold 402, pull the pull plates 801 around the second fixing plate 401 outwards. The insert plate 802 will exit from the lower slot 9. Directly remove the lower pressing mold 402, put in the new mold, and then loosen the pull plate 801. The insert plate 802 will automatically snap into the lower slot 9.
