随着运输业的迅速发展,车轮行业也日新月异。但拖拉机、轿车轮辋的生产工艺还比较落后,与之不相适应。我们用外模固定式施压成形新工艺代替陈旧的多道滚压成型工艺得到了较好的效果。1.产品特点与老工艺简介(1)产品介绍拖拉机、轿车轮辋形状(如图1)所示。其关键尺寸为轮辋的周长和跳动。轮辋周长过小,轮胎与轮辋之间产生相对滑动而无法传递动力,还会将气门嘴切断。周长过大,安装轮胎困难。
With the rapid development of the transport industry, the wheel industry is also changing rapidly. However, tractors, car rims production technology is still relatively backward, with incompatible. We use the outer mold fixed pressure forming new technology to replace the old multi-channel rolling process has been better results. 1. Product features and the introduction of the old process (1) Product Description Tractor, car rim shape (shown in Figure 1). The key dimensions are rim circumference and beating. Rim circumference is too small, there is a relative sliding between the tire and the rim can not transmit power, but also the valve cut off. Perimeter is too large, difficult to install tires.
