DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example

[0030] like Figures 1 to 8 As shown, the structure of the continuous stamping die for battery terminals of the present invention includes a lower die frame 1, which serves as the basic support structure of the die. The lower die frame provides a stable platform for mounting and securing other die components, including a lower die plate 2 symmetrically positioned thereon. The lower die plate is a key component of the die. Mounted on it are positioning components 3, including a floating plate 31, a locking block 32, a slider a33, and a slider b35. These components work together to ensure the precise positioning of the battery terminals during the stamping process. The design of the floating plate 31 allows it to move to a certain extent to accommodate battery terminals of different sizes, improving the versatility of the die. Two locking blocks 32 are mounted on the floating plate 31, each with a locking knob 321 for securing the floating plate's position and adjusting its tightness, ensuring the floating plate remains stable during the stamping process. Slider a33 is provided with a limiting groove a34 at its end. Slider a33 slides within the limiting groove a to provide initial positioning for the battery terminal. Slider b35 within slider a is provided with an arc-shaped positioning groove 36 at its end for secondary positioning of the annular portion of the battery terminal, further improving positioning accuracy. The lower mold plate is also provided with a trimming punch 21 between the floating plates for stamping and forming the battery terminal to achieve the desired shape and size. Slider a33 is also provided with a limiting protrusion 37 within the limiting groove a34 for secondary positioning of the battery terminal to prevent displacement during the stamping process. The advantages of this utility model include high-precision positioning. Through the design of primary and secondary positioning, the battery terminal is accurately positioned during the stamping process, reducing the scrap rate; modular design. The modular design of components such as the floating plate and slider facilitates rapid replacement and maintenance, improving production efficiency; and versatility and adaptability. The design of the floating plate enables the mold to accommodate battery terminals of different sizes and shapes, improving the mold's versatility. In summary, the battery terminal continuous stamping die structure of the present invention realizes efficient and precise production of battery terminals through sophisticated design. It is suitable for automated production lines and can significantly improve production efficiency and product quality while reducing production costs.

[0031] like Figure 2 and Figure 3In the structure of the continuous stamping die for the battery terminal, the design of sliders a33 and b35 incorporates several key features, including a stamping bevel 38, a limiting chute b351, and a limiting guide rod 331. The stamping bevel 38, located on the upper surfaces of sliders a33 and b35, is intended to guide and assist the stamping process, helping the material flow smoothly, reducing deformation and tearing, improving the precision and quality of the stamped parts, and guiding the material along a predetermined path to ensure the correct shape and size of the battery terminal during the forming process. The limiting chute b351, located on one side of slider b35, is used in conjunction with the limiting guide rod 331 to precisely control the position of slider b, ensuring it remains in the correct position during the stamping process and prevents lateral movement, thereby maintaining the positioning accuracy of the annular position of the battery terminal. Limiting guide rod 331, located within slider a33, cooperates with limiting guide groove b351 to ensure the relative position between sliders a and b, improving mold stability and preventing slider displacement caused by vibration or impact during the continuous stamping process. Based on the above analysis, these design features collectively improve mold stability and precision during the continuous stamping process, ensuring the molding quality of the battery terminal, and facilitating mold maintenance and adjustment, which is of great significance for improving production efficiency and reducing scrap rates.

[0032] like Figure 1 As shown, the lower die frame 1 is designed with an L-shaped track 11 to facilitate material loading. This provides a convenient path for smooth material feeding, ensuring accurate placement and continuous flow during the stamping process. This design not only improves production efficiency but also reduces material waste during operation and mitigates the risk of mold damage caused by improper material placement.

[0033] like Figure 1 As shown, the function of the proximity switch 12 is to send a signal to the control system when the material reaches a specific position on the L-shaped track 11. The push cylinder 13 is an actuator that performs actions based on the signal from the proximity switch 12. The proximity switch 12 can accurately control the position of the material on the L-shaped track 11 to ensure that the material is pushed by the push cylinder 13 at the right time. When the material moves along the L-shaped track 11 and reaches the turning point, the proximity switch 12 detects the presence of the material. After the proximity switch 12 is activated, the push cylinder 13 is activated. The push cylinder 13 performs a telescopic action according to the instructions of the control system, thereby pushing the material to continue moving along the L-shaped track 11 and enter the next processing link. The entire process does not require human intervention, which improves the degree of automation and efficiency of the production line. The use of the proximity switch 12 and the push cylinder 13 reduces the possibility of manual operation errors and improves production safety. Automated control reduces the number of operators and reduces labor costs.

[0034] like Figure 1 As shown, the lower mold frame 1 is evenly provided with a number of guide posts 22. These guide posts 22 are fixed vertically to the surface of the lower mold frame 1 and provide precise guidance and support for the floating plate 31 and other mold components. The function of the guide posts 22 is to ensure that the mold maintains a stable motion trajectory during the stamping process and to avoid a decrease in stamping accuracy due to relative displacement between mold components. Through the guidance of these guide posts 22, the upper mold plate can be accurately aligned with the lower mold frame 1 during stamping, thereby ensuring the stamping quality of the battery terminal and the service life of the mold. In addition, the guide posts 22 also facilitate the maintenance and replacement of the mold, as they can serve as a positioning reference during mold assembly and disassembly.

[0035] Working process

[0036] Before starting to stamp the battery terminals, the equipment is installed. The lower template 2 and other components are installed on the lower mold frame 1 in sequence through the positioning of the guide column 22. The equipment is turned on, and the semi-finished battery terminals enter the L-shaped track 11. When the material moves along the L-shaped track 11 and reaches the turning point, the proximity switch 12 detects the presence of the material. After the proximity switch 12 is activated, the push cylinder 13 is activated. The push cylinder 13 performs a telescopic action according to the instruction of the control system, thereby pushing the material to continue to move along the L-shaped track 11. At this time, the slider a slides outward, and the limit slide groove a32 is aligned with the limit slide groove 13. The edge of the material cooperates to complete the pre-positioning. At this time, the pushing cylinder 13 continues to push the material forward. When the slider b35 slides outward and the arc-shaped positioning groove 36 is engaged with the annular structure of the material, the initial positioning is completed. At this time, the floating plate 31 is pressed down to cooperate with the trimming punch 21 to complete the first stamping. At this time, the floating plate 31 returns to its position, and the pushing cylinder 13 continues to push the material forward. When the straight edge punched out on the battery terminal during the initial stamping contacts the limiting protrusion 37 set in the limiting slide groove a, the secondary positioning is completed, and stamping is performed again to complete the processing of a battery terminal. This cycle continues.
