Description

Technical Field

[0001] The utility model relates to the technical field of special steel casting, in particular to a stamping and fixing device for special steel casting. Background Art

[0002] Special steel, also called alloy steel, is a type of steel. Special steel is made by adding one or more alloying elements to carbon steel to change the structure of the steel, thus giving it various special properties.

[0003] During the processing and forming process of special steel, it needs to be stamped. The technicians engaged in special steel casting found in actual work that the fixed base cannot fix the special steel during casting, which makes the special steel easy to move during stamping, thereby reducing the stamping quality of special steel. In addition, the base cannot buffer the base during stamping, which easily causes damage to the base and reduces the service life of the base. For this reason, we propose a stamping fixing device for special steel casting. Utility Model Content
