Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal stamping dies, in particular to a sheet metal stamping die for automobile parts. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the die and deform it, thereby obtaining product parts of a certain shape, size and performance. Sheet metal, die and equipment are the three elements of stamping. According to the stamping temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates. It is one of the main methods of metal plastic processing and also belongs to material forming engineering technology. Sheet metal, a processing technology, has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold processing technology for metal sheets, including shearing, punching / cutting / compounding, folding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same part is consistent. Sheet metal stamping dies are needed when processing automotive parts.

[0003] The utility model patent with the patent application publication number CN 218192230 U discloses a sheet metal stamping die for automobile parts, wherein a mounting groove is provided at the bottom of the upper mounting seat, positioning blocks are provided on both sides of the top of the upper die, and a positioning vertical groove and a positioning arc groove are correspondingly provided on the side wall of the mounting groove, and the two are connected, the positioning arc groove is located at the top of the positioning vertical groove, and the positioning arc groove is arranged along the circumferential direction of the inner wall of the mounting groove, a bolt hole 1 is provided on the side wall of the upper die, and a bolt hole 2 is correspondingly provided on the side wall of the upper mounting seat, and the bolt hole 1 and the bolt hole 2 are both arranged in the horizontal direction, and a bolt 1 is installed inside both; the lower mounting seat is disc-shaped and rotatably arranged on the support platform of the stamping device, and two lower die mounting positions are provided on the lower mounting seat, and the lower die mounting positions are both installed with lower dies. The upper die of the utility model is more firmly installed, and it is not easy to shift up and down or rotate horizontally. Two lower dies are installed on the lower mounting seat, so that the upper and lower materials are separated at the stamping position to ensure the safety of the staff.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the lower mounting seat of the device is rotatably set on the support platform of the stamping device. When stamping automobile parts, the operator needs to rotate the mounting seat so that the lower mold is just under the upper mold. Only then can the automobile parts be stamped. However, in actual use, since the lower mounting seat is rotatably connected to the support platform, the operator needs to manually align the lower mold with the upper mold, which makes the operation difficult and reduces the operator's work efficiency. In addition, the lower mounting seat may also rotate during the stamping process, affecting the stamping effect.

[0005] Therefore, it is necessary to invent a sheet metal stamping die for automobile parts to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a sheet metal stamping die for automobile parts. By setting a lower die assembly, the problem proposed in the above background technology that the lower mounting seat of the device is rotatably set on the support platform of the stamping device is solved. When stamping automobile parts, the operator needs to rotate the mounting seat so that the lower die is just under the upper die. Only then can the automobile parts be stamped. However, in actual use, since the lower mounting seat is rotatably connected to the support platform, the operator needs to manually align the lower die with the upper die, which makes the operation difficult and reduces the work efficiency of the operator. In addition, the lower mounting seat may also rotate during the stamping process, affecting the stamping effect.
