铜管生产在半世纪前为直拉方式,国外从上世纪50年代开始有了盘拉方式,开始是采用正立式盘拉机和卧式盘拉机盘拉,到了70年代才有比较完整的自动控制的倒立式盘拉机。现代化最新技术的盘拉机开发于80年代末、90年代初。拉伸度最高可达1500m/min,7-8个料盘循环拉制,电控为数字系统PLC控制,开卷、盘拉、收卷三同步,自动排管,有人机对话系统,所有工艺参数均可设定、调整、并显示于显示屏上。这种盘拉方式与直拉相比,极大的提高了生产率、成材率。目前国内铜盘管主要用于空调器的两器用管(蒸发器及冷凝器),其次是冰箱管、热水器管等。内螺纹铜盘管占铜盘管的一半以上。
Copper production in the half-century before the Census, foreign countries from the last century 50’s began to pull the way, the beginning is the use of vertical and horizontal pull trays Panpan pull plate until the 70’s only more complete Automatic inverted tractor. The latest technology of modern disc machine developed in the late 1980s, early 90s. Stretching up to 1500m / min, 7-8 tray loop drawing, electronic control for the digital system PLC control, unwinding, disk pull, winding three simultaneous automatic drainage, man-machine dialogue system, all process parameters Can be set, adjusted, and displayed on the display. Compared with the Czochralski pull the way, greatly improved productivity, yield. At present, the domestic copper coil is mainly used for the two-way air conditioner pipe (evaporator and condenser), followed by the refrigerator tube, water heater tube. The female copper coil accounts for more than half of the copper coil.
