Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and relates to a multi-station automated precision stamping die for automotive outer waistline reinforcement plates. Background Technology

[0002] In related technologies, a waistline reinforcement plate is usually provided on the car door to strengthen and support the door structure. However, in order to ensure the lightweight of the car door, the waistline reinforcement plate, the rearview mirror bracket and the hidden handle bracket are integrally molded, which leads to the problem of increased door weight and increased cost.

[0003] Existing technologies typically use stamping to obtain automotive outer waistline reinforcement plates, employing stamping dies for manufacturing. In related existing technologies, the automotive outer waistline reinforcement plate requires several stamping processes from raw materials to blanks, including stamping, deburring, and stamping bending. After inspection and polishing, the finished automotive outer waistline reinforcement plate is obtained. Existing stamping dies have a single stamping station and cannot perform multi-station automated stamping. Therefore, we have designed a multi-station automated precision stamping die for automotive outer waistline reinforcement plates. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station automated precision stamping die for automotive outer waistline reinforcement plates, in order to solve the problems mentioned in the background art.

[0005] The purpose of this utility model can be achieved through the following technical solution: a multi-station automated precision stamping die for an automotive outer waistline reinforcement plate, comprising an integrated upper stamping die body and an integrated lower stamping die base, wherein the integrated upper stamping die body and the integrated lower stamping die base are connected in a mold closing configuration; The bottom of the integrated stamping upper die body is provided with a stamping forming part, a trimming part and a stamping bending part from left to right; The top of the integrated stamping lower die base is provided with a reinforcing plate stamping forming station seat, a reinforcing plate trimming station seat and a stamping bending station seat, from left to right. The stamping forming part, trimming part and stamping bending part of the integrated stamping upper die body correspond sequentially to the reinforcing plate stamping forming station, reinforcing plate trimming station and stamping bending station of the integrated stamping lower die body.

[0006] The aforementioned multi-station automated precision stamping die for automotive exterior waistline reinforcement plates also includes a stamping forming template located within the stamping forming section. This template comprises a contour frame, a power unit, six universal inserts, two first inserts, and two second inserts. The power unit is connected to the integrated upper stamping die body via bolts. The contour frame is mounted on the reinforcement plate stamping forming station seat. The six universal inserts, two first inserts, and two second inserts are spaced apart on both sides of the contour frame, forming the waistline contour. This arrangement allows for a spaced distribution, enabling the six universal inserts, two first inserts, and two second inserts to be sequentially combined on the contour frame, providing good adaptability and facilitating replacement and alteration of the waistline contour.

[0007] In the aforementioned multi-station automated precision stamping die for automotive outer waistline reinforcement plates, a trimming template is installed inside the trimming section via a connecting bracket, and the trimming template corresponds to the reinforcement plate trimming station seat. This configuration enables stamping and trimming of the outer waistline reinforcement plate.

[0008] In the aforementioned multi-station automated precision stamping die for automotive outer waistline reinforcement plates, a stamping and bending template is installed inside the stamping and bending section via a connecting bracket. This template corresponds to the stamping and bending station seat. The purpose of this arrangement is to stamp and bend the outer waistline reinforcement plate while simultaneously cutting off excess edge lines.

[0009] In the aforementioned multi-station automated precision stamping die for automotive exterior waistline reinforcement plates, the integrated stamping lower die base is also equipped with a discharge port. Inside the discharge port are a first guide rail and a second guide rail parallel to the first guide rail. The first and second guide rails connect the die cavities of the trimming template and the stamping bending template. This arrangement facilitates better collection of waste material generated during trimming and stamping bending.

[0010] Compared with existing technologies, the advantages of this utility model of multi-station automated precision stamping die for automotive outer waistline reinforcement plates are as follows: the stamping forming part, trimming part, and stamping bending part of the integrated stamping upper die body are sequentially aligned with the reinforcement plate stamping forming station, reinforcement plate trimming station, and stamping bending station of the integrated stamping lower die base. By adopting multi-station automated stamping, the number of dies required is reduced, which can greatly ensure the stamping accuracy and quality and shorten the time cost.
