630kN熔断丝油压机是西安重型机械研究所为香港精科公司研制的新产品,1992年9月通过验收,获得了用户的高度好评。这是我国第一台采用一次成形挤压工艺生产小直径熔断丝和焊锡丝的单机。它既可以生产带助熔剂芯的熔断丝和带松香芯的焊锡丝,还可以生产实心和空心的熔断丝和焊丝。它与国内已引进的多工序生产线相比,具有单机生产、一次成形、设备简单、投资少、成本低、劳动强度低、占地面积小、适应性广等优点。该油压机的关键是组合模具,它由挤压模和助熔剂容器两部分组成。首次挤压时,需将液态铟
630kN fusible link hydraulic press is a new product developed by Xi’an Heavy Machinery Research Institute for Hong Kong Jingke Company. It passed the check and acceptance in September 1992, and gained high praise from users. This is the first single machine in China that uses a single-pass extrusion process to produce small diameter fuse and solder wire. It produces both fluxed and fused rosin-based flux filaments, as well as solid and hollow fuses and wires. Compared with the multi-process production line introduced in China, it has the advantages of single machine production, one-time forming, simple equipment, low investment, low cost, low labor intensity, small occupied area and wide adaptability. The key to the hydraulic machine is a combined mold, which consists of an extrusion die and a flux container. The first squeeze, the need for liquid indium
