Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for rapid positioning and forming of sheet metal parts of household appliances. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm thick), including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming (such as car bodies), etc. Its most notable feature is that the thickness of the same part is consistent. Products processed by the sheet metal industry are called sheet metal parts. Stamping dies are a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the required parts. The existing sheet metal stamping forming dies have a simple structure, which affects the positioning of the device and the subsequent removal of materials. Therefore, we redesigned a quick positioning and forming home appliance sheet metal stamping die. Summary of the invention
