精冲技术,特别是在成形加工工艺方面,通过使用很少的工序,可加工出尺寸和形状精确的结构零件而具有重大意义。对薄板进行精冲一般是毫无问题的,但对板厚为8mm以上材料进行精冲时,则在冲裁面质量和尺寸精度方面还存在问题。有关研究工作报道,已对加工结果、模具以及压力机参数调整之间的基本关系进行了研究。 1.导言迄今为止,在为数众多的精密加工方法中F.schiess以后的精冲方法自成一体。由于尺寸
Fine blanking technology, especially in the area of forming processes, is of great importance by the use of very few processes for the production of structural parts of precise dimensions and shape. There is no problem with fine blanking of the sheet, but there is still a problem with the blanking surface quality and dimensional accuracy when fine blanking the sheet with a thickness of 8 mm or more. Relevant research reports have been carried out on the processing results, mold and press the basic parameters of the relationship between the adjustment. 1. INTRODUCTION So far, the fine blanking method after F.schiess has been self-contained in a large number of precision machining methods. Due to size
