由瑞士日内瓦的Dupont塑料技术中心研究的振动焊接塑料,已用于水泵的壳体和桨叶、加热器阀、燃料泵、蒸气熨斗的水箱及发动机油箱的焊接。振动焊接就是把两个零件用一定压力压在一起,并用120赫的频率使其中一个零件沿接合面处振动,从而产生摩擦热,经2～3秒停止振动,并使两个零件保持在精确位置上,短时保压,待冷却后即焊接完毕。这样一个工作循环约5～8秒,其接合强度接近材料本身强度。振动形式可采用直线或回转方
Vibration-welded plastics, studied at the Dupont Plastics Technology Center in Geneva, Switzerland, have been used to weld pump housings and blades, heater valves, fuel pumps, steam iron tanks and engine fuel tanks. Vibration welding is the pressure of two parts together with a pressure of 120 Hz and one of the parts along the joint surface at the vibration, resulting in frictional heat, after 2 to 3 seconds to stop the vibration, and to keep the two parts in precision Position, short-term packing, to be cooled after the welding is completed. Such a work cycle of about 5 ~ 8 seconds, the bonding strength close to the strength of the material itself. Vibration can be straight or rotary form
