前 言 12匹马力发动机曲轴箱的左右两半部,每件净重4公斤,采用ZL105合金,国内一采用低压铸造或砂型铸造工艺成型。 我厂在DC1000压铸机上生产12匹马力发动机左右两半部(见图1a.b)。 生产实践证明,该部件采用压铸工艺是一种多快好省的方法。 一、压铸设备 1.熔炼设备:采用QR—55倾斜式电阻熔化炉。熔化精炼后倒入保温炉使用。 Foreword 12 horsepower engine crankcase left and right halves, each net weight 4 kg, the use of ZL105 alloy, a domestic low-pressure casting or sand casting process molding. I plant in DC1000 die-casting machine to produce about 12 halves of the engine (see Figure 1a.b). Production practice has proved that the use of die-casting process is a component of the province faster and better way. First, the die-casting equipment 1. Melting equipment: QR-55 tilt resistance melting furnace. After melting and pouring into the holding furnace use.
