汽车车轮钢圈的体积大,所用材料为厚钢板,属于厚板大型冲压件。大跃进中我们试制三轮汽车时,需要450E-16前轮钢圈及550F-16后轮钢圈。当时曾有人考虑用进口货,但价格高;同时也有人考虑洋法制造,但需要成批巨大设备。我们在党的正确领导下,决定自行设计和制造双盆式车轮钢圈。它由两个盆形的冲压件用螺钉穿连,组成一个钢圈(图1)。它的优点如下:
Large car wheels steel ring, the material used for thick steel plate, belonging to the large-scale stamping parts. During the Great Leap Forward we trialled a three-wheeled vehicle that required a 450E-16 front wheel rim and a 550F-16 rear wheel rim. At that time, some people considered using imported goods but the price was high. At the same time, some people considered the manufacture of foreign products but needed huge quantities of equipment. Under the correct leadership of the party, we decided to design and manufacture double-basin wheel rims by ourselves. It consists of two basin-shaped stampings screwed together to form a steel ring (Figure 1). Its advantages are as follows:
