采用冲方加工工艺加工传动轴方孔,由于原冲方凸模端面为平端面,切削力较大,零件的表面粗糙度达不到图纸要求。每加工一件传动轴,需要更换7次冲方凸模和冲方加工7次,生产效率低,劳动强度大。通过改进冲方凸模结构,只需更换4次冲方凸模和冲方加工4次,就能生产出尺寸精度高,表面粗糙度低的传动轴零件,而且提高了生产效率,降低了生产成本。
For the flat end face of the original square punch in the punching technology of transmission shaft’s square hole,the cutting force is larger.Therefore the surface roughness of the part does not meet the requirements of the drawing.For the processing of each transmission shaft,it is needed to replace square punch seven times and punch seven times,so that production efficiency is low and labor intensity is high.Through improving the square punch structure,it is only needed to replace square punch four times and punch four times.Parts with high precision and low surface roughness can be produced.The production efficiency is improved and the cost of production is reduced.
