随着工程塑料用途的扩大,特别对玻璃纤维增强塑料二次加工要求也相应增加。以往采用的激光加工、超声波加工等,都各有优缺点,不是完善的加工方法。 本文所介绍的振动精冲塑料是新开发的加工方法,它是利用塑料导热性低,可在内部蓄热软化的特性。当给塑料振动折曲时,由振动能产生热,积蓄在塑料内部,使局部温度上升而被软化,随即切断就很容易。进而这软化了的切断面可复现出模具侧面形
With the expansion of the use of engineering plastics, especially for glass fiber reinforced plastic secondary processing requirements also increased accordingly. In the past using laser processing, ultrasonic processing, etc., all have their own advantages and disadvantages, not a perfect processing method. Vibration fine blanking introduced in this paper is a newly developed processing method, it is the use of plastic thermal conductivity is low, can be stored in the internal heat softening characteristics. When the plastic vibration bending, the heat generated by the vibration, accumulated in the plastic inside, so that the local temperature rise and be softened, then cut off is very easy. Further, the softened cut surface can reproduce the side shape of the mold
