鼓形弹簧(图1)要求密绕,是坦克电台机外天线支承弹簧。垂直支承着天线杆,受阻可弯曲120°,反复受阻仍保持垂直状态,被广泛应用于各国坦克天线上,其他场合使用也较多。当此弹簧大批生产时,可用大型绕簧机制造。在中小批生产又无大型绕簧机时,可采用组合式密绕鼓形弹簧胎具在普通车床上盘绕。将该组合式密绕鼓形弹簧胎具(图2)的开槽心轴左端夹在车床卡盘上,依次装好长结合套、组合式鼓形片、结合套,把弹簧钢丝装入开槽心轴槽内,用开槽套、压紧套、尾座顶尖顶紧固定。其他和一般绕簧一样,开车按胎具上的橄榄状螺旋槽绕制。
Drum spring (Figure 1) requires close-wound, tank radio outside the antenna support spring. Vertical support of the antenna rod, blocked by bending 120 °, repeatedly blocked still maintain the vertical state, is widely used in tank antennas in various countries, the use of other occasions are more. When the spring mass production, the machine can be used to create a large winding around. Small and medium batches of production in the absence of large-scale winding around the spring, the combination of dense drum-shaped spring can be used in ordinary lathe coiled. Clamp the left end of the slotted mandrel of the combined densely-wound drum-shaped spring mold (FIG. 2) on the lathe chuck, and then install a long coupling sleeve, a combined drum piece and a coupling sleeve in sequence to insert the spring steel wire into the open Groove heart slot, with slotted sleeve, compression sleeve, tail top tight top fastening. Like other general and around the spring, driving car by olive belly spiral wound on the system.
