The difference between stamping parts and castings: the characteristics of thin, uniform, light and strong stamping can produce workpieces with ribs, ribs, undulations or flanging that are difficult to manufacture by other methods to increase their rigidity. Due to the use of precision molds, the precision of the workpiece can reach the micron level, and the repeatability is high, the specifications are consistent, and the holes, bosses, osv . kan stanses ud .
Koldstemplede dele behandles generelt ikke længere ved at skære eller kræver kun en lille mængde skæring . Nøjagtigheden og overfladetilstanden for varme stemplingsdele er lavere end for kolde stemplingsdele, men det er stadig bedre end støbegods og smedning, og mængden af skæring er lille .}
Stamping klassificeres hovedsageligt i henhold til processen og kan opdeles i to kategorier: separationsproces og dannelse af proces .
The separation process is also called punching, and its purpose is to separate the stamping parts from the sheet material along a certain contour line, while ensuring the quality requirements of the separation section. Stamping is an efficient production method. It uses a compound die, especially a multi-station progressive die, which can complete multiple stamping processes on a single press to achieve a complete range from strip unwinding, leveling, punching til dannelse og efterbehandling . automatisk produktion .
High production efficiency, good labor conditions, low production cost, generally can produce hundreds of pieces per minute. The purpose of the forming process is to make the sheet plastically deform without breaking the blank to make a workpiece of the desired shape and size. In actual production, multiple processes are often applied to a workpiece. Punching, bending, shearing, drawing, svulmende, spinding og udretning er kun et par af de vigtigste stemplingsprocesser
