冲压件

For the all classes of dies, if we analyse the fluctuate, tendency of increase and decrease and law which appeared in the die's whole life, we will find that the master of the error are changeless; the error that because the abrade of the cutter and impression will be as the cutter grinding times increased at the same time.

新冲模在指定的冲压设备上投入使用至失效报废的整个寿命过程中，其合格冲件误差的主导部分固定不变即所谓固定误差。其大小就是新冲模第一次刃磨前冲制的合格冲件的偏差，也即冲模的初始误差，而此时的冲模具有初始冲压精度。

Advantages of traditional crank press technology include low production cost and high speed production rate (30~1200 pieces per minute). Requirements of complicated die and limited product forming are the shortcomings. Additionally, the advantages of traditional hydro-forming technology are good product quality, complicated geometric shape and easy-made die. However the disadvantages are expensive cost of equipment, low production speed (less than 5 pieces per minute), and is not applicable to multi-station progressive process and high pressure working environment that has the concern of industrial safety.

传统曲轴冲压技术之优点是生产成本低廉及生产速度快(每分钟30~1200件)，缺点是模具复杂及成品形状成形性受限制；传统液压成形技术之优点是成品品质佳、几何形状容许大变形及模具简易，缺点是设备成本高、生产速度很慢(每分钟5件以下)、不适合多工程连续加工且具有高压之工安问题。
