Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies, and particularly relates to a stamping die with a replaceable die head. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. Different stamping dies are used to stamp raw materials according to different needs. However, most common stamping dies cannot be replaced because their die heads are fixed and cannot be replaced. Such dies can only be used to produce products of a single specification or shape and are not universal. Once the product design changes or products of different shapes need to be produced, the die cannot be used any more and cannot meet the needs of diversified product production.

[0003] Secondly, if the die head is worn, damaged or needs to be optimized and improved, since the die head cannot be replaced alone, the entire mold may need to be replaced, which will increase repair and maintenance costs and extend downtime.

[0004] In addition, only the die head part of the entire mold may need to be updated, but the non-replaceable design means that even if other parts are still intact, they have to be scrapped together, resulting in a waste of resources.

[0005] In summary, the inability to replace the die head of the stamping die causes some problems during use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
