Abstract
Stamping die in industrial production in the extensive application. Stamping die design take full advantage of the characteristics of the function of mechanical press, at room temperature under conditions of the blank piece of stamping, more efficient production and significant economic benefits. Stamping die design take full advantage of the characteristics of the function of mechanical press, at room temperature under conditions of the blank piece of stamping, more efficient production and significant economic benefits. This paper describes the mold structure is simple and practical examples, easy to use and reliable, similar to parts of the mass production of certain references. In a traditional industrial production, production workers in the labour-intensive, and labor capacity, which has seriously affected the improvement of production efficiency. With today's technology development, industrial production in the mold of use has become increasingly arouse people's attention, a lot has been applied to industrial production in the past. Stamping die of automatic feed technology into actual production, stamping die can greatly increase labor productivity, reduce the burden on workers and has important significance of technological progress and economic value.
