[0037] See Figures 1-8 , Figure 1 This is a schematic diagram of the speaker wiring terminal structure in the embodiment. Figure 2 This is a schematic diagram of the changing structure of the feed strip in the embodiment. Figure 3 This is one of the schematic diagrams of the mold body structure in the embodiments. Figure 4 This is the second schematic diagram of the mold body structure in the embodiment. Figure 5 This is a schematic diagram of the upper mold structure in the embodiment. Figure 6 This is a schematic diagram of the lower mold structure in the embodiment. Figure 7 For the example Figure 6 Enlarged view of Part A Figure 8 For the example Figure 6 Enlarged view of part B. In this example, a continuous stamping die for a speaker terminal strip includes a die body 1 and two processing modules 2. The die body 1 includes an upper die 11 and a lower die 12. The upper die 11 is located directly above and opposite to the lower die 12. In use, the upper die 11 and the lower die 12 are respectively installed in a stamping device. During operation, the stamping device drives the upper die to move toward the lower die 12. At the same time, the strip passes continuously between the upper die 11 and the lower die 12.
[0038] Two processing modules 2 are arranged along the x-axis on the mold body 1 and distributed on both sides of the center line aa of the mold body 1. Along the y-axis, each processing module 2 includes a head forming module 21, a body forming module 22, and a finished product cutting module 23. Specifically, the head forming module 21 includes a head forming upper punch assembly 211 on the upper mold 11 and a head forming lower punch assembly 212 on the lower mold 22. The body forming module 22 also includes a body forming upper punch assembly 221 on the upper mold 11 and a body forming lower punch assembly 222 on the lower mold 12. The finished product cutting module 23 also includes a finished product cutting upper punch assembly 231 on the upper mold 11 and a finished product cutting lower punch assembly 232 on the lower mold 12.
[0039] During operation, the strip 01 passes between the upper die 11 and the lower die 12 and sequentially through the head forming module 21, the main body forming module 22, and the finished product cutting module 23. The stamping equipment drives the upper die 11 to reciprocate towards the lower die 22. When the strip 01 is located in the head forming module 21, the head forming upper punch assembly 211 pushes the strip 01 towards the head forming lower punch assembly 212 for stamping, so that the product head 021 is formed on the strip 01. Then, this part of the strip 01 moves to the main body forming module 22, and the main body forming upper punch assembly 221 and the main body forming lower punch assembly 222 jointly stamp the strip 01 to form the product body 022. Finally, this part of the strip 01 enters the finished product cutting module 23, and the finished product cutting upper punch assembly 231 and the finished product cutting lower punch assembly 232 jointly cut the product off the strip 01 to form the final product, which is the terminal 02 in this example.
[0040] It is understandable that since the mold body 1 is equipped with two sets of parallel processing modules 2, two sets of products can be processed simultaneously on the same strip 01 during the processing. This not only effectively improves processing efficiency, but also maximizes the utilization rate of the strip 01 material, avoids waste, and saves production costs.
[0041] See Figure 9 Review Figures 1-8 , Figure 9 This is a schematic diagram of the first upper cutting insert structure in the embodiment. Further, the head forming upper punch assembly 211 includes a first upper cutting insert 2111, which is embedded in the upper die 11 and located on the side of the upper die 11 away from the center line aa. One end of the insert has two opposing C-shaped punch heads 21111, which protrude from the upper die 11 towards the lower die 12. The lower die 12 has a first through hole 121 corresponding to the first upper cutting insert 2111. The head forming lower punch assembly 212 includes a first lower cutting insert 2121, which is disposed in the first through hole 121. The lower cutting insert 2121 has two C-shaped punch holes 21211 corresponding to the C-shaped punch heads 21111. 21211 is connected to the first through hole 121. The first cutting inserts 2111 of the two processing modules 2 are symmetrical along the center line aa. During operation, when the upper die 11 moves toward the lower die 12, the C-shaped punch head 21111 of the first cutting insert 2111 presses against the strip 01 toward the C-shaped punch hole 21211, thereby punching out two first C-shaped holes 011 on the strip 01, thus forming the product head 021. The generated waste is discharged through the C-shaped punch hole 21211 and the first through hole 121 to prevent waste from accumulating. It can be understood that during this process, the two processing modules 2 simultaneously form two symmetrical sets of C-shaped holes 011 on both sides of the strip 01, that is, simultaneously form two sets of product heads 021.
[0042] See Figure 10 Review Figures 1-8 , Figure 10 This is a schematic diagram of the structure of the first bending upper punch and the first bending lower punch in the embodiment. Further, the head forming upper punch assembly 211 also includes a first bending upper punch 2112, which is also embedded in the upper die 11 and is arranged adjacent to the first cutting upper insert 2111 along the y-axis direction. One end of the punch has a convex-shaped stamping block 21121. The first bending upper punches 2112 in the two processing modules 2 are staggered along the y-axis direction. The head forming lower punch assembly 212 has a first bending lower punch 2122 corresponding to the first bending upper punch 2112. The first bending lower punch 2112 is also embedded in the lower die 12, and its top end has a concave-shaped stamping block 2122 corresponding to the convex-shaped stamping block 21121. After the strip 01 is stamped by the first upper cutting insert 2111 and the first lower cutting insert 2121 to form the product head 021, this part of the strip 01 moves between the first upper bending punch 2112 and the first lower bending punch 2122. At this time, the product head 021 is located between the convex-shaped stamping block 21121 and the concave-shaped stamping block 2122. Then the convex-shaped stamping block 21121 moves toward the concave-shaped stamping block 2122, and the two press against each other to achieve the bending of the product head 021.
[0043] See Figure 11 Review Figures 1-8 , Figure 11 This is a schematic diagram of the insert structure on the second material cutter in the embodiment. Furthermore, the main body forming upper punch assembly 221 includes a second cutting upper insert 2211, which is disposed between the first bending upper punches 2112 of the two processing modules 2 and located on the center line aa of the mold body 1. The two processing modules 2 share the second cutting upper insert 2211. One end of the cutting insert 2211 has two back-to-back second C-shaped punches 22111. The two second C-shaped punches 22111 are symmetrically arranged on the center line aa and perpendicular to each other. The lower mold 12 is provided with a second through hole 122 corresponding to the second cutting upper insert 2211. The main body forming lower punch assembly 222 includes a second cutting lower insert 2221 embedded in the second through hole 122. The second cutting lower insert 2221 is provided with two second C-shaped punching holes 22211 corresponding to the second C-shaped punches 22111. The second C-shaped punching holes 22211 communicate with the second through hole 122. After the product head 021 in the strip 01 is bent, the strip 01 moves between the second upper cutting insert 2211 and the second lower cutting insert 2221. Similarly, the second C-shaped punch 22111 presses against the strip 01 toward the second C-shaped punching hole 22211, thereby forming the second C-shaped hole 012 on the strip 01, which is the tail end 02321 of the product. At the same time, the generated waste is discharged through the second C-shaped punching hole 22211 and the second through hole 122.
[0044] The main body forming upper punch assembly 221 also includes a punching insert 2212, which is embedded in the upper die 11 and located between the first bending upper punch 2112 and the center line aa. The punching inserts 2212 of the two processing modules 2 are symmetrically arranged along the center line aa, and one end of them has a punching pin 22121. The main body forming lower punch assembly 222 also includes a punching lower insert 2222. The lower die 12 is provided with a third through hole 123 corresponding to the punching insert 2212. The punching lower insert 2222 is located in the third through hole 123 and has a guide hole 22221. The guide hole 22221 is directly opposite the punching pin 22121 and communicates with the third through hole 123. After the product tail end 02321 is formed on the material strip 01, it continues to move between the punching insert 2212 and the punching lower insert 2222. The punching needle 22121 presses against the material strip 01 toward the guide hole 22221 to form a through hole 013 on the material strip, which forms the mounting hole 02311 of the product body 02. Similarly, the generated debris is discharged through the third through hole 123.
[0045] See Figure 12 Review Figures 1-8 , Figure 12 This is a schematic diagram of the third cutting insert structure in the embodiment. Furthermore, the main body forming upper punch assembly 221 also includes a third cutting upper insert 2213, which is embedded in the upper die 11 and adjacent to the first bending upper punch 2112 along the y-axis direction. The third cutting upper inserts 2213 of the two processing modules 2 are symmetrically arranged along the center line aa, and their extension lines are perpendicular to each other. One end of each insert has two strip-shaped cutting heads 22131, which are spaced apart and parallel to each other. The lower die 12 is provided with a corresponding third cutting upper insert 2213. The fourth through hole 124, the main body forming lower punch assembly 222 also includes a third cutting lower insert 2223, the third cutting lower insert 2223 is disposed in the fourth through hole 124, and two strip cutting holes 22231 are provided corresponding to the two strip cutting heads 22131. The two strip cutting holes 22231 are connected to the fourth through hole 124. The third cutting upper insert 2213 also has a cutting clearance groove 22132, the cutting clearance groove 22132 is located at the end of the strip cutting 22131 away from the center line aa. Similarly, after the material strip 01 forms the through hole 013, it continues to move between the third cutting insert 2213. The two strip cutting heads 22131 press against the material strip 01 toward the two strip cutting holes 22231, thus forming two parallel strip holes 014 on the material strip 01. At this time, the two parallel strip holes 014 are the front section 0231 of the main body 023 of the product 02. At the same time, the generated waste is discharged through the fourth through hole 124. Meanwhile, the cutting clearance groove 22132 can effectively prevent the product head 021 from interfering with the main body forming upper punch assembly 221.
[0046] See Figure 13 Review Figures 1-8 , Figure 13 This is a schematic diagram of the tail-end forming upper insert and tail-end forming lower insert in the embodiment. The main body forming upper punch assembly 221 also includes a tail-end forming upper insert 2214 embedded in the upper mold 11. The tail-end forming upper inserts 2214 of the two sets of processing modules 2 are located between the third cutting upper inserts 2213. They are located on both sides of the center line aa and are staggered along the y-axis direction. Their extension lines are also perpendicular to each other. Each tail-end forming upper insert 2214 has a first forming block 22141 at the end near the center line aa. The main body forming lower punch assembly 222 has a tail-end forming lower insert 2224 corresponding to the tail-end forming upper insert 2214. The tail-end forming lower insert 2224 is embedded in the lower mold 12 and has a second forming block 22241. The second forming block 22241 is directly opposite to the first forming block 22141. The longitudinal cross-section of the first forming block 22141 and the second forming block 22241 is triangular. After the material strip 01 forms the front section 0231 of the product body 023, this part of the material strip 01 moves to the space between the upper tail-end forming insert 2214 and the lower tail-end forming insert 2224. At this time, the tail end 02321 of the product is located between the two, and the lower tail-end forming insert 2214 faces the lower tail-end forming insert 2224, so that the first forming block 22141 and the second forming block 22241 press against each other to form the tail end 02321 of the product, so that the tail end 02321 forms a pointed tip.
[0047] See Figure 14 Review Figures 1-8 , Figure 14This is a schematic diagram of the first cutting upper insert structure in the embodiment. Further, the finished product cutting upper punch assembly 231 includes a first cutting upper insert 2311 embedded in the upper die 11. The first cutting upper insert 2311 is disposed along the y-axis direction behind the third cutting upper insert 2213. In the two sets of processing modules 2, the distance between the first cutting upper insert 2311 and the third cutting upper insert 2213 in one set of processing modules 2 is greater than the distance between the first cutting upper insert 2311 and the third cutting upper insert 2213 in the other set of processing modules 2. The first cutting upper insert 2311 has a first cutting head 23111. The head 23111 is aligned with the moving path of the material strip edge. The lower die 12 is also provided with a fifth through hole 125 corresponding to the first cutting upper insert 2311. The finished product cutting lower punch assembly 232 includes a first cutting lower insert 2321 embedded in the fifth through hole 125. The first cutting lower insert 2321 has a first dropping hole 23211. The first dropping hole 23211 is aligned with the first cutting head 23111 and is connected to the fifth through hole 125. The cross-sectional shape of the first dropping hole 23211 is consistent with the cross-sectional shape of the first cutting head 23111. After the product tail end 02321 forms a pointed tip on the material strip 01, the material strip 01 continues to move between the first upper insert 2311 and the first cutting insert 2321. The first cutting head 23111 is positioned between the heads 021 of two adjacent products. That is, when the first cutting head 23111 presses against the first dropping hole 23211, the first cutting head 23111 presses against the material between the heads 021 of two adjacent products in the material strip 01 and presses against the first dropping hole 23211, thereby cutting off the material between the heads 021 of two adjacent products in the material strip 01. At this time, the product head 021 and the front section 0231 of the product body 023 are separated from the material strip 01, and the generated waste is discharged through the fifth through hole 125.
[0048] See Figure 15 Review Figures 1-8 , Figure 15This is a schematic diagram of the upper and lower inlays of the main body bending structure in the embodiment. Furthermore, the main body forming upper punch assembly 221 also includes a main body bending upper insert 2215 embedded in the upper die 11. The main body bending upper insert 2215 is located behind the first cutting upper insert 2311 and on the side of the first cutting upper insert 2311 close to the center line aa. The extension lines of the main body bending upper inserts 2215 of the two processing modules 2 are perpendicular to each other. The main body bending upper insert 2215 has a first S-shaped bending surface 22151. The main body forming lower punch assembly 222 has a main body bending lower insert 2225 corresponding to the bending upper insert 2215. The main body bending lower insert 2225 has a second S-shaped bending surface 22251 corresponding to the first S-shaped bending surface 22151. The upper die 11 also has a bending clearance hole 111, which is located at the end of the first S-shaped bending surface 22151 away from the center line aa. After the front section 0231 of the product body 023 and the product head 021 are separated, the material strip continues to move between the upper insert 2215 of the main body bending and the lower insert 2225 of the product bending. At this time, the front end 0231 of the product body 023 is located between the first S-shaped bending surface 22151 and the second S-shaped bending surface 22251. When the upper insert 2215 of the main body bending presses towards the lower insert 2225 of the main body bending, the first S-shaped bending surface 22151 and the second S-shaped bending surface 22251 press against each other to form the front section 0231 of the main body 023, so that it forms an S-shaped connecting section 02312.
[0049] See Figure 16 Review Figures 1-8 , Figure 16This is a schematic diagram of the second upper cutting insert structure in the embodiment. The finished product cutting upper punch assembly 231 also includes a second upper cutting insert 2312 embedded in the upper die 11. Along the y-axis direction, the second upper cutting insert 2312 is located behind the main body bending upper insert 2215 and on the side closer to its center line aa. The second upper cutting insert 2312 has a second cutting head 23121. The cross-section of the second cutting head 23121 is consistent with the shape of the product tail section. The lower die 12 is provided with a sixth through hole 126 corresponding to the second upper cutting insert 2312. The finished product cutting lower punch assembly 232 also has a second lower cutting insert 2322 embedded in the sixth through hole 126. The second lower cutting insert 2322 has a second blanking hole 23221. The second blanking hole 23221 is directly opposite the second cutting head 23121. The cross-sectional shape of the second blanking hole 23221 is consistent with the overall cross-sectional shape of the product. Finally, after the product forms the S-shaped connecting section 02311, this part of the strip 01 moves between the second cutting upper insert 2312 and the second cutting upper insert 2322. The second cutting head 23121 presses against the strip 01 toward the second dropping hole 23221. The second cutting head 23121 cuts the tail section 0232 of the product body 023 from the strip 01. At this time, since the cross-section of the second dropping head 23121 is consistent with the cross-section of the product, the product falls out through the second dropping hole 23221 and the sixth through hole 126, thus completing the forming and collection of the product. Understandably, since the distance between the first cutting upper insert 2311 and the third cutting upper insert 2213 in one of the two processing modules 2 is greater than the distance between the first cutting upper insert 2311 and the third cutting upper insert 2213 in the other processing module 2, along the y-axis direction, the first cutting upper insert 2311, the main body bending upper insert 2215 and the second cutting upper insert 2312 in both processing modules 2 are staggered twice along the center line aa. In this way, not only is mutual interference of the second cutting head 23121 in the two processing modules 2 effectively avoided, but also the width of the strip 01 is saved to the maximum extent, thus saving material.
[0050] Preferably, the upper die 11 also has a strip cutting blade 112. The strip cutting blade 112 is located on the side of the upper die 11 near the finished product cutting insert 2312. One end of the strip cutting blade 112 is fixed to the upper die 11, and the other end protrudes towards the lower die 12, directly opposite the strip movement path. After the product is cut off from the strip 01, the strip 01 continues to move towards the die body 1 to below the strip cutting blade 112. As the upper die 11 continuously reciprocates towards the lower die 12, the cutting blade 112 cuts off the strip 01 that protrudes from the die body, facilitating waste collection.
[0051] In summary, in this example, since the mold body 1 is equipped with two sets of processing modules 2 arranged in parallel, two sets of products can be processed simultaneously on the same strip 01 during the processing. This not only effectively improves processing efficiency but also maximizes the utilization rate of the strip 01 material, avoids waste, and saves production costs.
[0052] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
