Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for producing a battery cover for an electric vehicle. Background Art

[0002] The stamping die for the production of electric vehicle battery covers is a high-precision and high-efficiency production tool specially designed for forming electric vehicle battery covers. The die includes multiple key components, such as a base, a screw lift, a servo motor and a workbench. Each part is responsible for a specific function and works together to achieve efficient and precise stamping operations. Its structural design not only focuses on precision and efficiency, but also considers the safety and convenience of operation. This die can ensure the consistency and quality of the product by precisely controlling the stamping depth and force, thereby improving production efficiency and reducing costs. Using this advanced stamping die, electric vehicle manufacturers can significantly improve their production capacity and market competitiveness.

[0003] In the current production of electric vehicle battery covers, the manufacturing process of the stamping die is usually completed by cutting and forming a whole piece of aluminum alloy material. The main purpose of this practice is to ensure that the die has the necessary rigidity, thereby ensuring its stability and durability during the production process. However, due to the specific structure and properties of the die itself, when the depth of the stamping groove inside it is too deep, the stamping plate may be embedded in the die and difficult to remove. Once this happens, it may seriously affect production efficiency and cause production interruptions, because the embedded plate may require additional manpower and time to remove. In addition, if the nested plate is forcibly removed, it may also cause damage to the die itself and shorten its service life. In view of this, we provide a stamping die for the production of electric vehicle battery covers. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] During the production process of the battery cover of the electric vehicle, if the stamping top die 201 is damaged, the No. 1 motor 205 on the inner side of the stamping top die 201 is activated to drive the bidirectional threaded rod 206 to rotate at its output end, and the threads provided at both ends of its outer wall respectively drive the multiple connecting plates 204 at both ends of the inner side of the stamping top die 201 to return to the inner side of the stamping top die 201. After one side of the outer wall of the connecting plate 204 is separated from the groove in the center of the auxiliary positioning sleeve 202, the stamping top die 201 can be taken out along the outer wall of the auxiliary positioning sleeve 202. When the stamping machine completes the processing of the plate through the device, the telescopic cylinder 303 on the inner side of the stamping bottom die 1 is started, and the output end of the telescopic cylinder 303 moves along the sliding rod The outer wall 305 drives the multiple limit shafts 304 fixed on both sides of the outer wall to move.

[0025] During the production process of electric vehicle battery covers, if the stamping top die 201 is damaged, the No. 1 motor 205 on one side of the inside of the stamping top die 201 is activated so that its output end engages with the conical teeth, driving the bidirectional threaded rod 206 to rotate in the center of the inside of the stamping top die 201, and through the threads provided at both ends of its outer wall, the multiple connecting plates 204 at both ends of the inside of the stamping top die 201 are driven to retreat along the outer wall of the slide rail 203 to the inside of the stamping top die 201. After one side of the outer wall of the connecting plate 204 is separated from the groove in the center of the auxiliary positioning sleeve 202, the stamping top die 201 can be taken out along the outer wall of the auxiliary positioning sleeve 202, thereby realizing rapid replacement or maintenance of the stamping top die 201, and effectively simplifying the maintenance process of the device, thereby reducing the production line downtime caused by maintenance.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a set of guide rails 301 are fixedly connected on both sides of the inner wall of the stamping bottom die 1, and the two sides inside the stamping bottom die 1 are slidably connected to the limit plates 302 through the guide rails 301, and one side of the outer wall of the guide rail 301 is simultaneously connected with the stripping plate 3 and the inner side of the limit plate 302, and the stripping plate 3 and the inner side of the limit plate 302 are simultaneously slidably connected with one side of the outer wall of the guide rail 301, the limit plates 302 are located on both sides of the bottom surface of the stripping plate 3, and the outer wall of the top end of the limit plate 302 is fixedly connected with one side of the bottom surface of the stripping plate 3, A telescopic cylinder 303 is fixedly connected to one side of the interior of the bottom pressing die 1, and both sides of the outer wall of the telescopic end of the telescopic cylinder 303 are fixedly connected to the limiting shaft 304, the outer wall of one end of the limiting shaft 304 is connected through the outer wall of the corresponding side of the limiting plate 302, and one end of the outer wall of the limiting shaft 304 is slidably connected to the bottom end of the limiting plate 302 through the telescopic cylinder 303, a sliding rod 305 is fixedly connected to the center of the interior of the stamping bottom die 1, and the center of the outer wall of the sliding rod 305 is slidably connected to the top end of the telescopic end of the telescopic cylinder 303.

[0027] When the punching machine has completed processing the plate through the device, the telescopic cylinder 303 on one side of the inside of the stamping bottom die 1 is started. When the output end of the telescopic cylinder 303 slides along the outer wall of the sliding rod 305, it drives multiple limit shafts 304 fixed on both sides of its outer wall to move. The limit shaft 304 pushes the limit plate 302 toward the top along the outer wall of the guide rail 301 through the oblique groove opened at the bottom end of the limit plate 302, so that the limit shaft 304 pushes the stripping plate 3 along the outer wall of the guide rail 301 through the limit plate 302 to lift the stamped plate to the top of the stamping bottom die 1. Therefore, the stripping plate 3, the guide rail 301, the limit plate 302 and the telescopic cylinder 303 cooperate with each other to realize the fully automatic demolding of the stamped plate in the production of the battery cover of the electric vehicle, so that the stamped plate can be quickly separated from the stamping bottom die 1, thereby effectively reducing the damage to the device itself caused by the embedding of the stamped plate in the device during the stamping process, and effectively avoiding the risk of injury caused by human error.

After one side of the outer wall of the connecting plate 204 is separated from the groove in the center of the auxiliary positioning sleeve 202, the stamping top die 201 can be taken out along the outer wall of the auxiliary positioning sleeve 202. When the punching machine uses the device to align the plate After the processing is completed, the telescopic cylinder 303 on one side of the inside of the stamping bottom die 1 is started, and the output end of the telescopic cylinder 303 drives the multiple limit shafts 304 fixed on both sides of the outer wall to move along the outer wall of the sliding rod 305. The limit shaft 304 passes through the oblique groove opened at the bottom end of the inner part of the limit plate 302, and pushes the limit plate 302 toward the top along the outer wall of the guide rail 301, so that the limit shaft 304 lifts the stamping plate to the top of the stamping bottom die 1, thereby realizing the full automatic demolding of the stamping plate in the production of the battery cover of the electric vehicle through the cooperation between the stripping plate 3, the guide rail 301, the limit plate 302 and the telescopic cylinder 303.
