摘　　要：大型薄板冲压液压机在作冲裁工艺时,噪声大,工作吨位受到限制。利用步进电机驱动皮带轮方法实现了冲裁装置缓冲缸的同步调节,降低了冲裁噪声,实现了全吨位冲裁,提高了液压机的使用效率,延长了寿命,保证了大型汽车覆盖件的冲压质量。The stamping technology for large sheet has some defects as the high noise and limited full load on the large scale stamping hydraulic press.The full load and low noise buffering device had been built through the belt wheel driven by stepping motor to synchronously adjust the full load stamping unit and buffering hydro—cylinder.The buffering device can reduce production noise to 80dB,and achieve the full load stamping technology,which extends the lifetime of the press and promotes the quality of panel cover for large automobile.
