一、前言对小批量或试制件的冲压来说,都希望从产品设计到投入生产的周期尽量缩短。这就要使模具制造迅速,并在不影响冲件制造精度的前提下,尽量简化模具结构,以降低模具的制造成本. 我们利用激光切割速度高、适于切割复杂平面曲线及生产费用较低等优点,将3mm厚的钢板作为凹模的基体板,并迅速地加工出凹模工作部分的轮廓;同时又采用数块硬钢板进行多次积层,得到了符合几
First, the introduction of small batch or trial parts stamping, all hope that from product design to put into production as short as possible the cycle. This will make the mold quickly, and without affecting the accuracy of the pieces of production under the premise, as much as possible to simplify the mold structure to reduce the manufacturing costs of the mold. We use the laser cutting speed, suitable for cutting complex plane curve and lower production costs And other advantages, the 3mm thick steel plate as the base plate die, and die quickly machined part of the outline; at the same time using a few pieces of hard steel for multiple lamination, obtained in line with a few
