摘要
分析了液压挤压机挤压无铅喷金料时出线(杆)速度波动大的原因。更换油泵并采用变频控制后,显著减小了挤压速度的波动,满足了挤压工艺的要求。
The causes of extrusion speed fluctuating during extruding the lead - free thermal - spraying metal, which is used for spraying metallized layer on capacitor end, in a hydraulic extrusion press are analyzed in this paper. After exchanging oil pump and adopting frequency controlling, the fluctuation of extrusion speed is greatly reduced and satisfied the requirements of extrusion process.
