碗形轴瓦是大型圆锥破碎机中的重要零件。碗形轴瓦的尺寸及精度要求都比较高,铸件毛重1350公斤,它的质量优劣将直接影响我厂大型破碎机制造及机器的使用寿命。我厂大型碗形轴瓦的批量制造采用金属型成型离心铸造工艺,生产出了优质成型铸件,下面把这种碗形轴瓦的离心铸造工艺介绍如下: 一、零件 零件结构和尺寸见图1。 材质为ZQSnPb 10—5锡铅青铜、净重530公斤。 Bowl bushings are important components in large cone crushers. Bowl-shaped bearing the size and accuracy requirements are relatively high, castings gross weight 1350 kilograms, its quality advantages and disadvantages will directly affect the plant’s large crusher manufacturing and machine life. I plant a large bowl-shaped pad bulk manufacturing using metal-forming centrifugal casting process to produce high-quality molded castings, the following bowl-shaped bearings of the centrifugal casting process is as follows: First, the parts structure and dimensions shown in Figure 1. Material ZQSnPb 10-5 tin-lead bronze, net weight 530 kg.
