Technical Field
[0001] The utility model belongs to the field of stamping dies, and particularly relates to a die that can quickly adjust the punching position and shape. Background Technique
[0002] A punching die (also known as a stamping die) is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly known as a cold punching die). Punching (also known as stamping) is a pressure processing method that applies pressure to the material by using a die installed on a press at room temperature to cause separation or plastic deformation, so as to obtain the required parts.
[0003] When it is necessary to adjust the punching holes of the same shape at different positions of the product, the current processing solution is to disassemble the original die, take out the template for processing and modify the punching tool; or when it is necessary to form punching holes of different shapes on the product, the processing solution is to add a punching hole of a different shape at the next station, so that punching holes of different shapes can be punched on the same die.
