[0002] Stamping is a process that uses a die under the strong pressure of a press to force metal sheets (usually coils or sheets) to undergo plastic deformation or separation, thereby obtaining parts with a certain shape, size and properties.

[0003] With the continuous development of the automotive industry, more and more automotive parts are being processed using stamping. Many automotive parts have non-standard, irregular shapes, and stamping allows for the design of parts tailored to specific vehicle models or functional requirements, with smaller batch sizes compared to standard parts. For example... Figure 1 As shown, this is a non-standard irregular structure. The processing steps usually require three steps. The first step is to stamp and cut the steel plate into steel plate units of the corresponding shape and size. The second step is to stamp the steel plate units into the corresponding shape. The third step is to stamp and cut out the corresponding holes.

[0004] Therefore, it is urgent to solve the problem in the existing technology that the processing of automotive parts requires first stamping and cutting steel plates into steel plate units of corresponding shapes and sizes, and then stamping the steel plate units into shape, which results in a complicated process that is time-consuming and labor-intensive.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] To address the technical problem of cumbersome and time-consuming processes in automotive parts manufacturing, which require stamping and cutting steel plates into corresponding shapes and sizes before stamping, this invention provides an automotive parts stamping die. This die allows material to be placed within a shearing structure. Driven by a first stamping mechanism 500, a first upper die core 400 is inserted into the shearing structure to cut the material. Simultaneously, driven by the first stamping mechanism 500, the first upper die core 400 and the first lower die core 200 stamp the material's shape. This combines the original steps of first cutting the material and then stamping, simplifying production steps, reducing processes, and saving production time.

[0034] Please see Figures 1 to 7 , Figure 1 For manufactured automotive parts, Figures 2 to 7A schematic diagram of the structure of an automotive parts stamping die in one embodiment of this utility model. The automotive parts stamping die includes: a base 100, a first lower die core 200, a shearing block 300, a first upper die core 400, and a first stamping mechanism 500. The first lower die core 200 is connected to the base 100 and is disposed for placing materials. The shearing block 300 is connected to one side of the first lower die core 200, and a shearing structure is formed between the top plane of the first lower die core 200 and the side wall of the first lower die core 200. The first upper die core 400 is disposed opposite to the first lower die core 200. The first stamping mechanism 500 is connected to the first upper die core 400 and is used to drive the first upper die core 400 to move closer to or away from the first lower die core 200, and to drive the first upper die core 400 to cooperate with the shearing block 300 or the first lower die core 200 respectively to cut materials and stamp the cut materials.

[0035] In this device, a shearing structure is formed on one side of the first lower die core 200. The material is placed inside the shearing structure. Driven by the first stamping mechanism 500, the first upper die core 400 can be inserted into the shearing structure to cut the material. At the same time, driven by the first stamping mechanism 500, the first upper die core 400 and the first lower die core 200 can stamp the material into shape. This combines the original steps of cutting the material first and then stamping it, which simplifies the production process, reduces the number of processes, and saves production time. It can solve the technical problem that the processing of automotive parts requires stamping and cutting steel plates into steel plate units of corresponding shapes and sizes before stamping the steel plate units, which leads to complicated and time-consuming processes.

[0037] Furthermore, the shearing block 300 is disposed on one side of the first lower die core 200. The long strip of steel plate material enters the shearing structure along the side where the shearing block 300 is disposed. When the first stamping mechanism 500 drives the first upper die core 400 to insert into the shearing structure, the long strip of steel plate material can be cut and the cut steel plate unit can be stamped. Therefore, the long strip of steel plate material can form continuous feeding and production.

[0050] Two opposing and spaced-apart guide blocks 730 are connected to the base 100 via a support 720, and the two guide blocks 730 together guide the material.

[0051] Furthermore, grooves are provided on opposite sides of the two guide blocks 730, making the guide blocks 730 in an inverted "L" shape, which can clamp or limit the material and improve the stability of the material during feeding.

[0052] In one embodiment, please refer to Figure 4 The bottom plane of the guide chute is coplanar with the top plane of the fixed base 600.

Here, the second lower die core 810, the second upper die core 840 and the second stamping mechanism 830 are all conventional settings known to those skilled in the art, and will not be described in detail here.

A shearing block 300 is connected to the first lower die core 200, and a shearing structure is formed between the top plane of the first lower die core 200 and the side wall of the first lower die core 200. Under the drive of the first stamping mechanism 500, the first upper die core 400 can move closer to or further away from the first lower die core 200 to drive the first upper die core 400 to cooperate with the shearing block 300 or the first lower die core 200 respectively to cut the material and make the cut material stamped into shape. Compared to existing technologies, by forming a shearing structure on one side of the first lower die core 200, the material is placed inside the shearing structure. Driven by the first stamping mechanism 500, the first upper die core 400 can be inserted into the shearing structure to cut the material.

[0070] In the specific workflow of this utility model, when processing automotive parts, the user manually feeds the long strip-shaped material into the guide trough and conveys it along the guide channel to the shearing structure. Then, driven by the first stamping mechanism 500, the first upper die core 400 stamps the material, and the shearing surface 410 cooperates with the shearing block 300 to cut the long strip-shaped material into steel plate units, which are then stamped. The worker then removes the cut and stamped material from the first lower die core 200 and sends it to the second lower die core 810, so that the cut and stamped material and... The protrusions on the second lower die core 810 fit tightly together. Finally, driven by the second stamping mechanism 830, the second upper die core 840 and the punching part 820 form a stamping of the material, so that the middle hole and edge material of the material being cut and stamped are removed. The removed hole waste can be discharged outward along the stamping hole, and the edge material is separated under the action of the first floating plate 850 and the second floating plate 860. The worker then removes the processed parts and edge waste respectively, thus completing one production process. By repeating the above steps, continuous production can be achieved, which can effectively reduce production steps and improve production efficiency.
