Description

Technical Field

[0001] This utility model belongs to the field of terminal block processing technology, specifically relating to an integrated stamping and riveting mold for composite terminals. Background Technology

[0002] In automotive architecture, wiring harnesses are like the blood vessels and nerves of the entire vehicle, serving as core components that ensure vehicle safety, support lightweight design, and maintain signal integrity. Terminals, as core elements of the wiring harness, are critical nodes for achieving circuit conduction and signal transmission. Their connection reliability, insertion / removal lifespan, and assembly precision directly determine the operational stability and safety level of the entire vehicle's electrical system.

[0003] As the automotive industry continues to upgrade, the comprehensive performance requirements for terminals are becoming increasingly stringent. Terminals must simultaneously meet multiple performance indicators such as low contact resistance, high contact elasticity, wear resistance, and creep resistance. Traditional single-material terminals often use high-conductivity materials such as pure copper and brass to ensure conductivity. However, these materials generally have inherent shortcomings such as low yield strength, weak elastic recovery, and poor wear resistance. Therefore, composite terminals have emerged. They employ a composite structure combining a main body and a functional component. The main body is typically made of materials such as copper, while the functional component is made of materials such as stainless steel. While retaining excellent conductivity, they also possess outstanding contact elasticity, fatigue resistance, and high-frequency insertion and extraction stability.

[0004] The current production process of riveted composite terminals is as follows: First, the main body stamping die and the functional body stamping die are used to process the main body strip and the functional body strip respectively; then, the two strips are simultaneously fed into the riveting die, and the main body and the functional body are riveted together by pressing.

[0005] However, this cross-station riveting process has the following problems: During the process of transporting the main material strip from the stamping station to the riveting station, the terminal body on the strip is prone to tilting and lateral deviation relative to the side carrier, making it difficult for the main body and functional body to be accurately aligned at the riveting station, resulting in defective products; at the same time, the layout of cross-station transfer not only increases the equipment footprint and material turnover cost, but also significantly increases the difficulty of alignment and debugging of the two sets of material strips; in addition, in order to offset the deformation risk during transfer, it is often necessary to increase the proportion of material strip carrier and add positioning holes to maintain the conveying rigidity, which directly increases the material scrap rate. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides an integrated stamping and riveting mold, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a composite terminal punching and riveting integrated mold, including an upper mold base and a lower mold base, wherein a main material strip travel channel and a functional material strip travel channel 1 are distributed and intersected between the upper mold base and the lower mold base; the main material strip travel channel is provided with a processing station 1, a riveting station and a discharge station 1 in sequence along the feeding direction, and two rows of guide pins are provided on the main material strip travel channel; the functional material strip travel channel 1 passes through the riveting station, and a stepping feeder is provided on the functional material strip travel channel 1.

[0008] By adopting the above solution, this utility model integrates stamping and riveting into a single mold, significantly reducing material turnover links, equipment footprint, and production turnover costs; by simply adjusting the feeding speed and pitch of the functional strip, the alignment accuracy of the riveting station can be guaranteed, thereby improving the yield of finished products.

[0009] As a further feature of this utility model, the riveting station is provided with an upper seat and a lower seat arranged opposite to each other. The upper seat and the lower seat are respectively provided with an upper through groove and a lower through groove on their opposite surfaces. The upper through groove and the lower through groove are both arranged to extend along the extension direction of the functional material strip travel channel one. The bottom of the lower through groove is provided with a pressure rod protruding upward from the through groove.

[0010] Using the above scheme, the functional body is covered by the main body. During riveting, the upper through groove can limit the functional body to be riveted on the functional body strip, and the lower through groove is used to fix the functional body to be riveted to the main body.

[0011] As a further feature of this invention, each side wall of the upper through groove includes an upper fixed wall and a clearance wall disposed on the side of the lower fixed wall away from the bottom of the lower through groove, and the two clearance walls are far apart from each other on the side away from the bottom of the upper through groove; each side wall of the lower through groove includes a lower fixed wall and a guide wall disposed on the lower fixed wall away from the bottom of the upper through groove, and the two guide walls are far apart from each other on the side away from the bottom of the lower through groove; the upper fixed wall and the clearance wall, and the lower fixed wall and the guide wall are connected by an arc-shaped transition surface; the end of the pressure rod facing the upper through groove is located between the two guide walls.

[0012] The above solution can better fit the shape of the main body and the functional body to be riveted, ensuring the riveting effect.

[0013] As a further feature of this invention, the upper seat is provided with a protruding end that protrudes from the lower seat, the upper through groove is provided on the protruding end, and the depth of the upper through groove in the direction away from the lower seat is greater than the height of the protruding end. The two outer walls of the protruding end facing away from each other approach each other on the side near the lower seat. When the upper seat and the lower seat abut, the protruding end is located between the two guide walls on both sides of the lower through groove, and there is a clearance gap between the outer wall of the protruding end and the corresponding guide wall.

[0014] Using the above solution, the protruding end structure can penetrate deep into the lower through groove, shortening the stamping stroke and improving riveting accuracy; the clearance between the protruding end and the guide wall can avoid collision and interference between the upper and lower seats when the mold is closed, while ensuring mold alignment and improving the consistency of the riveting position.

[0015] As a further feature of this utility model, the first processing station includes a punching guide hole station, a cutting station, a cutting station, and a forming station arranged sequentially towards the riveting station; the two rows of guide pins are staggered, with one row of guide pins away from the stepper feeder extending from the cutting station to the discharge station, and the other row of guide pins near the stepper feeder extending from the cutting station to the cutting station.

[0016] Using the above scheme, the main body's guide hole processing, contour punching, unit separation, and bending forming are completed sequentially; the guide pins and guide holes can correct feeding errors in real time. The two rows of guide pins are arranged in an alternating manner, which not only ensures the feeding guidance accuracy before the cutting station, but also avoids the punching action of the cutting station, thus preventing interference between the guide pins and the punching structure.

[0017] As a further feature of this utility model, a correction station is provided on the first travel channel of the functional material strip. The correction station is located between the stepper feeder and the riveting station, and a correction needle is provided on the correction station.

[0018] Using the above scheme, after the functional body material is stamped, there is a guide hole with the same function as the guide hole of the main body material strip. When the functional body material strip moves through the stepper feeder, the functional body material strip after step feeding can be finely positioned again by the cooperation of the straightening pin and the guide hole, so as to offset the cumulative error of step feeding and improve the riveting alignment accuracy between the functional body and the main body.

[0019] As a further feature of this invention, the lower mold base is also provided with a second functional strip travel channel parallel to the main strip travel channel. The second functional strip travel channel is provided with a punching guide hole station, a second cutting station, a second cutting station, a second forming station, and a second discharge station in sequence along the feeding direction. A stepping feeder is provided at the second discharge station. The second functional strip travel channel is provided with two rows of guide pins, both of which extend from the second cutting station to the second discharge station.

[0020] The above solution matches the overall process rhythm of the functional strip with that of the main strip. This achieves integrated stamping and riveting of the main body and functional strip, further reducing the production line footprint. Stamping with the same mold reduces tolerance accumulation from multiple production lines, improving the dimensional matching between the main body and functional strip. The guide pins and guide holes work together to ensure the stamping feeding accuracy of the functional strip, and the stepper feeder matches the stamping rhythm, ensuring stable output.

[0021] As a further feature of this invention, the first functional strip travel channel includes a waste discharge station located on the side of the riveting station away from the stepper feeder, and the waste discharge station and the second discharge station are arranged intersectingly; both the straightening station and the waste discharge station are provided with lifting seats, and both the main strip travel channel and the second functional strip travel channel are located on the side of the first functional strip travel channel near the lower die base.

[0022] By adopting the above scheme, the functional material strip travel channel is raised by raising the seat, forming a stacked layout with the main body and functional stamping channel below. Combined with the staggered discharge design of scrap and finished products, material discharge interference can be avoided, the overall length of the mold can be greatly reduced, and the structure can be made more compact. At the same time, the stacked layout can shorten the spacing between the intersecting channels and improve the structural rigidity of the riveting station.

[0023] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0029] Specific embodiments of this utility model are shown in the accompanying drawings.

[0030] Appendix Figure 1 The completed composite terminal includes a main body a and a functional body b; (attached) Figures 4-5The system includes a main material strip A and a functional material strip B. The main material strip A includes a crimping section A1 and an insertion section A2.

The system has a three-sided enclosed structure. The two functional side walls B2 are provided with spring tabs B3, and a retaining tab B4 is provided on the side away from the functional top wall B1. A notch A4 is provided on the main bottom wall A3. After bending, the notch A4 corresponds to the inner wall of the main side wall A6. A limiting protrusion B5 is provided on the functional top wall B1, which limits the movement of the main top wall A5 towards the crimping section A1.

[0031] This embodiment discloses a composite terminal stamping and riveting integrated mold, including an upper mold base and a lower mold base 1. A main material strip travel channel 2, a functional material strip travel channel one 3, and a functional material strip travel channel two 4 are distributed between the upper mold base and the lower mold base 1. The main material strip travel channel 2 and the functional material strip travel channel one 3 are intersected, and the main material strip travel channel 2 and the functional material strip travel channel two 4 are parallel to each other.

[0032] The main material strip travel channel 2 is provided with a punching guide hole station 21, a cutting station 22, a cutting station 23, a forming station 24, a riveting station 25, and a discharge station 26 in sequence along the feeding direction. The main material strip travel channel 2 is provided with two rows of parallel and staggered guide pins 27. The row of guide pins 27 closer to the functional body material strip travel channel 2 4 extends from the cutting station 22 to the discharge station 26, and the row of guide pins 27 farther away from the functional body material strip travel channel 2 4 extends from the cutting station 22 to the cutting station 22.

[0033] The functional body strip travel channel 3 passes through the riveting station 25. Along the feeding direction, the functional body strip travel channel 3 is sequentially equipped with a stepping feeder 31, a straightening station 32, and a waste discharge station 33. The riveting station 25 is located between the straightening station 32 and the waste discharge station 33. The straightening station 32 is equipped with a straightening pin 321, and both the straightening station 32 and the waste discharge station 33 are equipped with lifting seats 34. After stamping, the functional body strip B has a guide hole B1 that functions identically to the guide hole A1 of the main body strip A. When the functional body strip B moves through the stepping feeder 31, the straightening pin 321, in conjunction with the guide hole B1, can perform secondary precision positioning of the functional body strip B after stepping feeding, offsetting the accumulated error of stepping feeding and improving the riveting alignment accuracy between the functional body b and the main body a.

[0034] The functional strip travel channel 2 4 is sequentially equipped with a punching guide hole station 41, a cutting station 2 42, a cutting station 2 43, a forming station 2 44, and a discharge station 2 45 along the feeding direction. A stepping feeder 451 is installed at the discharge station 2 45. Two rows of parallel guide pins 46 are provided on the functional strip travel channel 2 4, both rows of guide pins 46 extending from the cutting station 2 42 to the discharge station 2 45. The guide pins 46 can achieve stable guidance of the functional strip B throughout the entire process, ensuring the smoothness of stamping and feeding. The scrap discharge station 33 is arranged intersecting with the discharge station 2 45. The main strip travel channel 2 and the functional strip travel channel 2 4 are both located on the side of the functional strip travel channel 1 3 near the lower die holder 1.

[0035] The riveting station 25 is provided with an upper seat 5 and a lower seat 6 arranged opposite to each other. The upper seat 5 and the lower seat 6 are respectively provided with an upper through groove 51 and a lower through groove 61 on their opposite surfaces. The upper through groove 51 and the lower through groove 61 are both arranged to extend along the extension direction of the functional body material strip travel channel 3. Both sides of the upper through groove 51 include an upper fixed wall 52 and a clearance wall 53 disposed on the side of the lower fixed wall 62 away from the bottom of the lower through groove 61. The two clearance walls 53 are far apart from the bottom of the upper through groove 51. Both sides of the lower through groove 61 include a lower fixed wall 62 and a guide wall 63 disposed on the lower fixed wall 62 away from the bottom of the upper through groove 51. The two guide walls 63 are far apart from the bottom of the lower through groove 61. The upper fixed wall 52 and the clearance wall 53, and the lower fixed wall 62 and the guide wall 63 are connected by arc-shaped transition surfaces. The bottom of the lower through groove 61 is provided with a pressure rod 7 protruding upward from the upper through groove 51. The end of the pressure rod 7 facing the upper through groove 51 is located between the two guide walls 63. The upper seat 5 has a protruding end 54 that protrudes from the lower seat 6. An upper through groove 51 is provided on the protruding end 54, and the depth of the upper through groove 51 in the direction away from the lower seat 6 is greater than the protruding height of the protruding end 54. The two outer walls of the protruding end 54 facing away from each other are close to each other on the side near the lower seat 6. When the upper seat 5 and the lower seat 6 abut, the protruding end 54 is located between the two guide walls 63 on both sides of the lower through groove 61, and there is a clearance between the outer wall of the protruding end 54 and the corresponding guide wall 63. In this embodiment, the outer wall of the protruding end 54 and the corresponding guide wall 63 are parallel to each other. The structure of the protruding end 54 can penetrate deep into the lower through groove 61, shorten the stamping stroke, and improve the riveting accuracy. The clearance between the protruding end 54 and the guide wall 63 can avoid collision interference between the upper seat 5 and the lower seat 6 when the mold is closed, while ensuring the alignment of the mold and improving the consistency of the riveting position.

[0036] After riveting station 25 completes one riveting operation, the main material strip A on the main material strip travel channel 2 moves, causing the riveted main material strip A to move out of riveting station 25, and causing the main body a to be riveted to move into the space between the upper seat 5 and the lower seat 6 of riveting station 25; subsequently, the functional body material strip B on the functional body material strip travel channel 3 moves, causing the carrier of the functional body material strip B that has been riveted to move out of riveting station 25, and causing the functional body b to be riveted to move into the space between the upper seat 5 and the lower seat 6 of riveting station 25. At this point, the middle of the functional sidewall b2 of the functional body b to be riveted is bent, causing the sides of the two functional sidewalls b2 with the retaining piece b4 to move away from each other. At this time, there is a 90° angle between the retaining piece b4 and the functional sidewall b2. The upper seat 5 and the lower seat 6 approach each other, so that the functional top wall b1 of the functional body b to be riveted fits into the bottom of the upper through groove 51, and the two functional sidewalls b2 fit into the upper fixed wall 52 of the upper through groove 51, with a gap between them and the clearance wall 53. Subsequently, the connection between the functional sidewall b2 and the retaining piece b4 is subjected to force by the guide wall 63, and the connection between the two functional sidewalls b2 and the retaining piece b4 approaches each other. At the same time, the pressure rod 7 moves into the notch a4 and pushes the two retaining pieces b4, so that the two retaining pieces b4 correspond to the inner wall of the main sidewall a6 of the main body a. Finally, the upper seat 5 and the lower seat 6 move away from each other, completing one riveting operation.

[0037] Compared to existing technologies, this embodiment integrates stamping and riveting into a single mold, achieving a fully integrated process of simultaneous stamping and riveting of the main body a and functional body b. This significantly reduces material turnover links, equipment footprint, and production turnover costs. Furthermore, stamping with the same mold can reduce the accumulation of tolerances from multiple production machines, effectively improving the dimensional matching between the main body a and functional body b.

[0038] The guide pin 27, in conjunction with the guide hole A1, can correct feeding errors in real time. The two rows of guide pins 27 on the main material strip A are staggered, which not only ensures the feeding guidance accuracy before the cutting station, but also avoids the punching action at the cutting station, preventing interference between the guide pin 27 and the punching structure, and effectively preventing the main material strip A from skewing or deviating when it travels to the riveting station 25. The guide pin 46, in conjunction with the guide hole B1, achieves stable guidance throughout the process. The stepping feeder 451 matches the stamping cycle, so that the overall process cycle of the functional strip B matches the overall process cycle of the main material strip A, reducing the accumulation of tolerances in multi-equipment production, improving the dimensional matching degree between the main body a and the functional body b, and ensuring the feeding stability during the stamping and feeding process.

[0039] The stepper feeder, used in conjunction with functional strip B, allows for precise adjustment of the feeding speed and step distance, ensuring the alignment accuracy of riveting station 25 and improving the yield of finished products. The lifting seat 34 elevates the functional strip travel channel 3, forming a stacked layout with the stamping channels of the main body a and functional body b below. Combined with the staggered discharge design of scrap and finished products, this avoids discharge interference, significantly reducing the overall length of the mold and making the structure more compact. Simultaneously, the stacked layout shortens the spacing between intersecting channels, enhancing the structural rigidity of riveting station 25.

[0040] This utility model is not limited to the specific embodiments described above. Those skilled in the art can implement this utility model using other specific embodiments based on the content disclosed in this utility model. Any simple changes or modifications made to the design structure and concept of this utility model will fall within the protection scope of this utility model.
