Technical Field
[0001] This utility model relates to the field of mobile phone parts processing technology, specifically a precision stamping pull-out part for producing riveting bushings for mobile phone connectors. Background Technology
[0002] Precision stamped pull parts for mobile phone connector riveting bushings refer to components produced by precision stamping and pulling processes for riveting mobile phone connectors. Pulling stamping is a forming process that uses a press and mold to apply external force to sheet metal, strip, etc., causing plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size. Precision stamped pull parts for mobile phone connector riveting bushings utilize this process to process metal sheets into bushings of specific shapes and sizes for the assembly of mobile phone connectors.
[0003] In the current stamping process for producing riveting bushings for mobile phone connectors, the riveting grooves are often not precise enough, resulting in deviations and misalignments. This leads to the inability to install and assemble the bushings during assembly, requiring manual adjustments and reducing the automation level of the production line. Riveting bushings for mobile phone connectors that cannot be adjusted will be discarded, increasing production costs.
[0004] Therefore, this utility model provides a precision stamping drawing part for the production of riveting bushings for mobile phone connectors to solve the above problems. Utility Model Content

[0007] As a preferred technical solution of this application, a process connection groove is provided on the surface of the carrier near the drawing boss. The process connection groove is elongated and parallel to the axial direction of the drawing boss.
[0008] As a preferred technical solution of this application, a transition forming groove is provided on the surface of the carrier on the other side near the drawing boss. The transition forming groove is an irregular corrugated groove structure opened on the surface of the carrier.
[0009] As a preferred technical solution of this application, an auxiliary forming groove is provided on the surface of the carrier above the drawing boss. The auxiliary forming groove is irregular in shape and is adapted to the radial direction of the drawing boss.
[0010] As a preferred technical solution of this application, a main body forming cavity is formed on the surface of the carrier below the drawing protrusion, and the main body forming cavity is a composite stepped concave cavity structure.
[0011] As a preferred technical solution of this application, a drawing cavity is provided on the side of the carrier near the process connection groove, and the drawing cavity is a square chamfered groove.

[0016] (III) Beneficial Effects This utility model features a simple structure and convenient operation. Through the combined use of positioning holes and square positioning slots, it achieves precise positioning of parts during multi-station precision stamping, ensuring the consistency of stamping features in each process, improving the stability of mass production and the precision of parts. The combined use of drawing bosses and protrusions enables precise forming of the core functional structure of the mobile phone connector riveting bushing. The composite stepped concave cavity structure of the main forming cavity allows for simultaneous layered forming of the bushing's main contour, meeting the high-precision assembly requirements of micro-parts. Subsequently, the irregularly shaped design of the process connecting groove, transition forming groove, and auxiliary forming groove provides buffer and guiding space for material flow during stamping, avoiding cracking or deformation of parts caused by localized stress concentration, and ensuring the integrity of the formed structure. The L-shaped structure and mirror symmetric layout of the hanging feet achieve a stable connection between the drawing cavity and the carrier, ensuring reliable transmission during continuous stamping and providing a clear benchmark for the subsequent separation and cutting of the bushing finished product from the carrier, improving production efficiency. The irregular, stepped, and symmetrical designs of each structure are fully compatible with the precision stamping process of mobile phone connector riveting bushings, achieving the production advantage of "one-time forming and multi-feature integration."

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides a precision stamped drawing part for the production of riveting bushings for mobile phone connectors, such as... Figures 1-4 As shown, a precision stamping drawing part for producing a mobile phone connector riveting bushing includes a carrier 1. Positioning holes 2 are provided on both sides of the carrier 1. A drawing boss 3 is provided on the surface of the carrier 1. A protrusion 4 is fixedly connected to the upper surface of the drawing boss 3. The protrusion 4 is conical in shape. The cooperation between the drawing boss 3 and the protrusion 4 can accurately form the core functional structure of the mobile phone connector riveting bushing.
[0021] A process connection groove 5 is provided on the side of the carrier 1 near the drawing boss 3. The process connection groove 5 is elongated and parallel to the axis of the drawing boss 3. A transition forming groove 6 is provided on the other side of the carrier 1 near the drawing boss 3. The transition forming groove 6 is an irregularly shaped corrugated groove structure on the surface of the carrier 1. An auxiliary forming groove 7 is provided on the surface of the carrier 1 near the top of the drawing boss 3. The auxiliary forming groove 7 is irregularly shaped and adapted to the radial direction of the drawing boss 3. The irregularly shaped structure design of the process connection groove 5, the transition forming groove 6 and the auxiliary forming groove 7 provides buffer and guiding space for the material flow during stamping, avoids cracking or deformation of parts caused by local stress concentration, and ensures the integrity of the formed structure.
[0022] The surface of the carrier 1 is provided with a main body forming cavity 8 below the pull-out boss 3. The main body forming cavity 8 is a composite stepped cavity structure. The composite stepped cavity structure of the main body forming cavity 8 can simultaneously complete the layered forming of the bushing body contour, meet the high-precision assembly requirements of small parts, and each step of the composite stepped cavity can be used as a "positioning reference" for subsequent finishing and inspection processes. For example, the coaxiality of the bushing can be calibrated by the high step surface, and the flatness of the bottom can be detected by the low step surface. At the same time, the low step cavity can serve as a clearance space for the installation of internal components (such as conductive terminals) of the bushing, avoiding structural interference between the components and the bushing body, and ensuring the smooth realization of the overall function of the connector.
[0023] A drawing cavity 9 is provided on the side of the carrier 1 near the process connection groove 5. The drawing cavity 9 is a square chamfered groove. The drawing cavity 9 and the process connection groove 5 work together. The process connection groove 5 provides material replenishment and stress buffer space for the forming of the drawing cavity 9. The two work together to realize the process integration of "cavity forming and material transition", improve the feature forming efficiency of single stamping, and adapt to the needs of multi-feature integrated production of mobile phone connector riveting bushing.
[0024] The bottom of the drawing cavity 9 is fixedly connected to a hanging foot 10, which is an L-shaped pad. The L-shaped structure and mirror symmetrical layout of the hanging foot 10 realize a stable connection between the drawing cavity 9 and the carrier 1, which not only ensures the reliability of the continuous stamping transmission, but also provides a clear benchmark for the subsequent separation and cutting of the bushing finished product from the carrier 1, thereby improving production efficiency. The irregular, stepped, and symmetrical designs of each structure are fully compatible with the precision stamping process of the riveting bushing of the mobile phone connector, realizing the production advantage of "one-time molding and multi-feature integration".
[0025] A positioning square groove 11 is provided at the edge of the carrier 1. The positioning square groove 11 is arranged in a linear array at the edge of the carrier 1. The positioning square groove 11 can realize the precise positioning of parts in the multi-station precision stamping process, ensure the positional consistency of stamping features in each process, and improve the stability of mass production and the precision of parts.
[0026] The hanging feet 10 are arranged in a mirror symmetrical manner at the bottom of the drawing cavity 9, and the upper surface of the hanging feet 10 is flush with the cavity opening plane of the drawing cavity 9. The mirror symmetrical arrangement design allows the drawing cavity 9 to be evenly fixed on the carrier 1 by the hanging feet 10, avoiding uneven force on one side of the hanging feet 10, which would cause the drawing cavity 9 to shift or tilt during multi-station continuous stamping and forming process, ensuring the alignment accuracy between the drawing cavity 9 and the mold, and thus ensuring the forming consistency of the bushing functional structure.
[0027] Positioning holes 2 are linearly arrayed on the surface of carrier 1. The positioning holes 2 are circular holes. The standardized layout of the linear array is compatible with the programmed positioning logic of automated stamping equipment. The equipment can achieve uniform positioning of carrier 1 in different batches without frequent adjustment of positioning parameters, reducing errors caused by manual intervention. At the same time, the circular holes are easy to process and the precision is easy to control. This can ensure that the size, spacing and height of the positioning holes 2 on carrier 1 in the same batch or even different batches are consistent, providing a basic guarantee for the consistency of parts in mass production and avoiding deviations in the functional structure of the bushing due to differences in positioning reference.
[0028] Specifically, a customized precision stamping die is installed on the stamping equipment. Metal sheets meeting the thickness and material requirements are selected as raw materials. Initial debugging of the equipment and die is completed. Then, the metal sheet is placed in the corresponding area of the carrier 1 of the stamping die. Precise positioning of the sheet is achieved through the positioning holes 2 on both sides of the carrier 1 and the positioning square grooves 11 on the edge, in conjunction with the positioning mechanism of the die, ensuring the positional accuracy of subsequent stamping processes. Subsequently, the sheet is initially stamped to form the drawing boss 3 and the top conical protrusion 4. Simultaneously, the preliminary outlines of the process connection groove 5, transition forming groove 6, auxiliary forming groove 7, and main forming cavity 8 are stamped at corresponding positions on the surface of the carrier 1. Then, each structure is sequentially precision stamped to achieve the desired effect. The elongated irregular structure of the process connection groove 5, the irregular corrugated groove of the transition forming groove 6, the irregular structure of the auxiliary forming groove 7, the composite stepped concave cavity of the main forming cavity 8, and the square chamfered groove of the extraction cavity 9 achieve the design precision. At the same time, the hanging foot 10 at the bottom of the extraction cavity 9 is formed, ensuring that the hanging foot 10 is mirror symmetrical and its upper surface is flush with the cavity opening plane of the extraction cavity 9. After all the structures are stamped, a special cutting die is used to precisely cut along the connection edge between the hanging foot 10 and the carrier 1, so that the finished mobile phone connector riveting bushing is separated from the carrier 1, and a single finished bushing is obtained. Subsequently, the dimensions and structural precision of the separated bushing are inspected. Qualified products are uniformly stored and enter the subsequent assembly process of the mobile phone connector.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
