Description

Technical Field

[0001] This utility model belongs to the field of automotive rear panel processing technology, and relates to a multi-station automated precision stamping integrated structure for automotive rear panels. Background Technology

[0002] The rear panel of a car typically refers to the covering located at the rear of the vehicle, mainly including the following structures: Trunk lid; as an important rear cover, it primarily protects the items inside the trunk and serves an aesthetic purpose, using lightweight materials to reduce weight. Rear bumper cover; located under the trunk, it buffers collision impacts and protects the vehicle body structure; some models use plastic materials to reduce weight. Rear bulkhead: the supporting structure connecting the trunk lid and the rear bumper; some models have thicker steel plates for improved safety. Taillight assembly: lighting devices integrated into the trunk lid or rear bumper, including reversing lights and brake lights, which need to be kept clean and in normal working condition.

[0003] In the existing technology, automotive rear panel parts are obtained by hot stamping dies. However, the disadvantages of traditional stamping dies are that the stamping of the rear panel and the material support are not integrated structures, and the material support of the rear panel does not have a good positioning effect. To address this, we have designed an integrated structure for multi-station automated precision stamping of automotive rear panels. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station automated precision stamping integrated structure for automotive rear panels, in order to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: a multi-station automated precision stamping integrated structure for automotive rear panels, including an upper rear panel stamping die and a lower rear panel stamping die. The lower rear panel stamping die is connected to the upper rear panel stamping die. The top of the lower rear panel stamping die is provided with a first rear panel stamping station and a second material support stamping station. The bottom of the first rear panel stamping station is provided with a station holder integrally connected to the lower rear panel stamping die. The top of the first rear panel stamping station is provided with a left panel limiting seat and a right panel limiting seat. The left and right panel limiting seats form stamping die cavities. Both the left and right panel limiting seats have rear panel outlines.

[0006] In the aforementioned multi-station automated precision stamping integrated structure for automotive rear panels, multiple material support positioning components are provided on the second stamping station. Each material support positioning component includes an inclined mounting block installed inside the second stamping station. A limiting top block is installed on the inclined end of each inclined mounting block, and a tensioning connecting rod is provided at one end of each limiting top block. A material support fixing end is provided at one end of the tensioning connecting rod. The purpose of this arrangement is to better position the material, resulting in better material support stability and improved stamping accuracy and quality during the stamping process.

[0007] In the aforementioned multi-station automated precision stamping integrated structure for automotive rear panels, a sliding limit block is installed at the top of each of the aforementioned limit blocks. This design facilitates further adjustment of the limit distance, ensuring better contact with the material support area.

[0008] In the aforementioned multi-station automated precision stamping integrated structure for automotive rear panels, the bottom end of the upper stamping die for the rear panel is equipped with a rear panel stamping moving die and a material support stamping moving die, which correspond to the first stamping station of the rear panel and the second stamping station of the material support, respectively. This arrangement facilitates better integrated stamping forming, allowing the rear panel and the material support at the first stamping station and the second stamping station of the material support to be stamped into place in a single operation.

[0009] In the aforementioned multi-station automated precision stamping integrated structure for automotive rear panels, guide post mounting seats are fixedly provided on both sides of the bottom end of the upper rear panel stamping die. Guide posts are installed inside the two guide post mounting seats to guide the upper rear panel stamping die to the lower rear panel stamping die. This design aims to provide excellent guiding performance, ensuring that the positional accuracy of the upper rear panel stamping die remains constant when it is guided to the lower rear panel stamping die.

[0010] Compared with the prior art, the advantages of this utility model of a multi-station automated precision stamping integrated structure for automotive rear panels are as follows: By setting a rear panel stamping station and a material support stamping station at the top of the rear panel stamping die, and setting a left panel limiting seat and a right panel limiting seat at the top of the rear panel stamping station, the left panel limiting seat and the right panel limiting seat form a stamping die cavity. This allows for integrated stamping of the rear panel and the material support, facilitating better matching and use of the rear panel and the material support. At the same time, multiple material support positioning components are set on the material support stamping station, which can better position the material support, resulting in better stability of the material support and better stamping accuracy and quality during the stamping process.
