一、胶筒的旋压加工旋压胶筒的工艺流程印刷机胶筒的零件图如图1.从图可以看出,胶筒只对内孔尺寸精度、表面粗糙度要求较高.选用旋压加工的工艺流程为:下料、车外圆、初镗内孔、半精镗内孔、旋压、平两端定长短.旋压坯料图如图2所示.旋压坯料的晶粒度若大于四级将影响材料的可旋性,可能产生旋压裂纹等问题.所以,要求材料进行正 First, the plastic cylinder spinning process The plastic cylinder process printing machine parts map of the cylinder shown in Figure 1. As can be seen from the figure, the plastic cartridge only bore size accuracy, surface roughness requirements are higher. Pressure processing of the process as follows: cutting, the car outside the circle, the beginning of boring bore, semi-fine boring bore, spinning, flat ends fixed length. Spinning blank diagram shown in Figure 2. Spinning blank grain If the degree is greater than four will affect the material’s spinnability, spinning problems may arise.Therefore, the material is required to be positive
