由上海电器科学研究所设计,江苏宿迁机床厂试制的JZ1504转子压铸机,于4月27日在上海由江苏省机械工业厅组织鉴定。参加鉴定会议的有机械委电器局、沈阳电工专用设备研究所、机械委第八设计院及有关电机厂共20个单位40名代表。会议认为该机压射力较大、压射比压较高,有利于提高铸铝转子内在质量;样机经上海跃进、南京电机厂分别压铸640台和200多台转子;证明其运行可靠、性能稳定、操作方便,所压铸的转子充型良好、轮廊清晰、成品率达99.2％;设备刚性好、结构紧凑、布局合理、占地面积较小;该机具有自动切浇口系统,减轻了劳动强度。为此,会议一致同意,该机可以投入批量生产。
The JZ1504 rotor die-casting machine trial-designed by Shanghai Electric Institute of Science and Technology and Jiangsu Suqian Machine Tool Factory was appraised by the Machinery Industry Department of Jiangsu Province on April 27 in Shanghai. To participate in the appraisal meeting, there are 40 representatives from Machinery Commission Bureau of Electrical Equipment, Shenyang Electrical Equipment Institute, the 8th Design Institute of Mechanical Committee and the relevant motor factory. Meeting that the aircraft injection pressure is larger, the injection pressure is higher, is conducive to improving the inherent quality of cast aluminum rotor; prototype by Yuejin in Shanghai, Nanjing Motor Factory Die Casting 640 and 200 respectively rotor; prove its reliable operation, performance Stable and easy to operate. The die-cast rotors are well-charged and the vestibule is clear with a finished product rate of 99.2%. The equipment has good rigidity, compact structure and reasonable layout, and occupies a small area. The machine has an automatic cutter gate system, Labor intensity. To this end, the meeting agreed that the aircraft can be put into mass production.
