我厂引进的美国DS公司水泥车的PG柱塞泵上的重要零件吸入凡尔和排出凡尔是由美国格软特油具公司生产供应给DS公司的,属于该公司专利,因而无原厂技术资料。试制这种凡尔体,锻件成形是一个难题。因为凡尔体四个导向爪,横截面积小且长(如图1所示),只能采用挤压成形的方法才能锻造成形;而挤压成形的方法又是锻造成形方法中较难的一种。适用于挤压成形的锻压设备是高速锤和热模锻压力机,这两种设备我厂均没有。根据我厂现有设备只能采用胎模 I introduced the plant in the United States DS cement pump PG plunger pump on the important parts of the inhalation of Versailles and discharge of Versailles by the United States Gert soft special oil company supplies DS company, belongs to the company’s patent, so no original factory Technical Information. Trial of this kind of Vernal, forging forming is a problem. Because of the four guiding claws of Versailles, the cross-sectional area is small and long (as shown in Fig. 1), only forging can be formed by the extrusion forming method; and the extrusion forming method is more difficult in the forging forming method A. Forging equipment for extrusion is a high-speed hammer and hot forging presses, the two devices I plant are not. According to our existing plant can only use the tire mold
