Description

Technical Field

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

[0002] At present, automobile body panels refer to various parts used to cover, protect and beautify the automobile body structure, including doors, roofs, window frames, hoods, trunk lids, etc. They are usually made of metal sheets, have good rigidity and strength, and also need to have a beautiful appearance and aerodynamic design.

[0003] At present, the forming stamping dies for automobile body covering parts mainly include the following types:

[0004] Single-station die: Single-station die is suitable for simple-shaped body panels and usually consists of an upper die and a lower die. Through the movement of the punch, the upper die presses the metal sheet, interacting with the lower die to form the metal sheet into the desired shape.

[0005] Multi-station die: Multi-station die is suitable for complex-shaped body panels, and can complete multiple forming steps in the same stamping process. It consists of multiple stations, each with a corresponding upper and lower die. Through the cyclic movement of the stamping machine, the metal sheet is gradually formed at different stations.

[0006] Linear die: Linear die is suitable for long strip body panels, such as door frames. It consists of multiple upper and lower dies arranged in a certain linear arrangement. Through the movement of the punching machine, the metal sheet is punched in different die positions in turn to form the desired shape.

[0007] Multi-step die: Multi-step die is suitable for body panels with multiple detail requirements. It decomposes a complex stamping process into multiple steps, and realizes multiple stamping and forming of metal sheets at different stations through the combination of multiple upper and lower dies.

[0008] However, the existing molds are unable to perform stamping operations on the sides of special-shaped automobile body covers. The automobile body covers need to be stamped multiple times at different mold positions, resulting in low processing efficiency. In addition, during the forming process of the automobile body covers, there is a problem of demolding difficulties. Traditional stamping molds may encounter the problem of parts sticking to the mold during demolding, resulting in the finished parts being unable to smoothly separate from the mold. The existing demolding mechanism usually uses a core pulling mechanism for demolding. The core pulling mechanism uses a cylinder core pulling, which has a complex structure and is inconvenient to repair when problems occur with the equipment.
