我厂锻工车间利用过去呆滞零件(图1),改制成了新型吊杆(如图2)。吊杆要求头部黑皮不加工,但由于呆料比吊杆长且薄,采用坚起来镦粗,头部容易缺肉,杆部(厚度与长度相比为12.5∶1)也容易弯曲。后来小组研究出一种方法,顺利地完成了改制任务。由于这种方法可适用于各种薄型锻件的压缩,所以把它介绍出来,供大家参考。胎模如图3所示,由钢板焊接而成,两端 Our factory forging workshop using the past dull parts (Figure 1), transformed into a new type of boom (Figure 2). The boom requires no black leather on the head, but the tendons tend to buckle because they are longer and thinner than the boom and are upset by firm up and the head is easily missing. The stem (12.5: 1 in thickness vs. length) also bends easily. Later, the team developed a method to successfully complete the restructuring task. As this method can be applied to a variety of thin forging compression, so introduce it for your reference. Figure 3 shows the tire mold, welded by steel plate, both ends
