汽车纵梁的结构形状虽然简单,但在其冲裁和弯曲成形工序上实现自动或机械化运输,确是一件颇棘手的事情.这是因为该零件为细长簿板件,在纵向极易变形,尤其坯料在单件或小批量吊装时,会自由弯曲,这给工序中的运输带来极大的不便和不安全.如欲用人工输送,约需6～8人抬上搬下,使人易疲劳,稍有不慎,随时都有可能发生人身事故.此外, Although the structural shape of the car stringer is simple, automatic or mechanized transport in the blanking and bending process is a tricky thing, because the part is a slender plate that is extremely easy in the machine direction Deformation, especially in the single piece or small batch hoisting, will be free to bend, which brings great inconvenience and unsafe transport in the process.If you want to use artificial delivery, about 6 to 8 people carried up and down, Make people easy to fatigue, a little careless, at any time there may be personal accident.In addition,
