Brief analysis of international development of stamping die in Dalian

In recent years, with the process of globalization, the international competition of manufacturing industry has become more and more fierce. In order to remain invincible in the competition, many enterprises are committed to "reduce costs", "shorten delivery time", "improve quality" and other topics.



The small cutting depth and large feed cutting are widely used in the die and mould industry to achieve high efficiency machining, but the market demand requires further improvement of the machining efficiency. In view of this need, the tool has developed a multi cutting edge tool and a coating which can bear high cutting speed under the condition of large feed. The design idea of multi blade large feed fillet cutter is to reduce the cutting edge size in the limited cutter diameter, according to the previous cutting edge design method, but it will not reduce the blade edge strength.



Dalian stamping die design is reasonable to improve the durability of stamping die foundation. Therefore, in the design of stamping die, the measures should be taken to improve the durability of the stamping die, such as the design of small hole stamping die life is often displayed on the punch punch hole. For this kind of stamping die, the small convex die should be shortened as far as possible to increase the strength in the design, meanwhile, the guide sleeve method should be adopted to strengthen the small punch to protect.



The precision of stamping die has a great influence on the durability of stamping die. If the assembly gap is not uniform in the blanking die, the die will often bite under the shear force, which will affect the life of the stamping die. At the same time, the surface roughness of the stamping die is too low, and the durability of the stamping die will be reduced.



From the industry structure, the rapid development of private enterprises, state-owned enterprises vitality, quantity and ability of professional mold manufacturers for the improvement of the market quickly, to adapt to the stamping mold production processing characteristics of mold industry agglomeration production park development, the Midwest and other mould industry underdeveloped regions have greater progress.
