图1所示零件是日本引进的草席自动编织机上的过草针,材料为H62和H68,每一种型号的过草针分左右对称两件,单台数量多。从图可以看出该零件具有复杂的截面形状和空间弯曲尺寸。从实物分析看,日本是采用辗轧型材,再用冲模切断弯曲加工而成的。我厂接受加工零件任务后,根据我国尚
The parts shown in Fig. 1 are grass-knitting needles on the automatic knitting machine for mats imported from Japan. They are made of H62 and H68. There are two pieces of symmetrical two pieces of grass needle in each type, with a large number of single pieces. It can be seen from the figure that the part has a complicated cross-sectional shape and space bending size. From the physical analysis, Japan is the use of rolling profiles, and then cut off the bending process from the punch. After I accept the task of machining parts, according to our country Shang
