扩孔机是高效率生产环形锻件的专用设备。因此,用扩孔机辗压环形件时,可使环形锻件有高的生产率和高的锻件质量,且能大大减轻劳动强度。适宜于在水压机上直接成形的环形件最好也能在扩孔机辗扩。我厂参照济南铸锻机械研究所提供的图纸和上海电机厂制造的φ1300毫米扩孔机,成立了由工人,技术人员和干部参加的三结合班子。联系本厂实际情况和加工条件,对图纸作了部分设计修改,并已于一九七六年十月制造完工φ1300毫米扩孔机壹台,并顺利的通过试车,目前已能单件小批试生产。φ1300毫米扩孔机工作原理示意见图1。
Reaming machine is a high-efficiency production of ring forgings special equipment. Therefore, the ring with a reaming machine rolling ring, can make the ring forging a high productivity and high forging quality, and can greatly reduce labor intensity. The rings, which are suitable for direct forming on a hydraulic press, are also preferably rolled up in a reaming machine. I plant with reference to Jinan Casting Machinery Institute for the drawings and the Shanghai Electric Factory manufacturing φ1300 mm reaming machine, set up by the workers, technicians and cadres to join the three combination. Contact the factory actual conditions and processing conditions, the drawings made part of the design changes, and in October 1976 completed the completion of φ1300 mm reaming machine Taiwan, and successfully passed the test, has been able to single piece small batch Trial production. φ1300 mm reaming machine working principle shown in Figure 1.
