摘要：【中文】本发明公开了有芯股多股圆柱螺旋弹簧钢索拧制缠绕一次成型方法，包括：将钢丝卷制至第一线盒、第二线盒并分别固定在第一支架、第二支架上；第二线盒中的钢丝穿过支架轴的中心孔，第一线盒中的钢丝穿过套筒进入支架轴的中心孔，钢丝合并后经过出丝口穿出，合并后钢丝的端头固定在缠绕芯轴的固定套上；主轴带动固定套转动，从固定在刀架上的出丝口抽出钢丝；同时支架轴转动，将第一线盒中抽出的钢丝、第二线盒中抽出的钢丝拧成钢索，实现了钢索的制造；第一支架、第二支架及其传动机构固定在车床大托板上，随大托板1横向移动，钢索在缠绕芯轴上形成了多股簧。本发明能够确保有芯股多股圆柱螺旋弹簧拧制钢索与弹簧缠绕一次成型。 【EN】The invention discloses a one-step forming method for twisting and winding a cored strand multi-strand cylindrical spiral spring steel cable, which comprises the following steps: rolling the steel wire to a first wire box and a second wire box and fixing the steel wire on a first support and a second support respectively; the steel wire in the second wire box penetrates through the central hole of the support shaft, the steel wire in the first wire box penetrates through the sleeve and enters the central hole of the support shaft, the steel wires penetrate out through the wire outlet after being combined, and the end head of the combined steel wire is fixed on the fixing sleeve of the winding core shaft; the main shaft drives the fixed sleeve to rotate, and a steel wire is drawn out from a wire outlet fixed on the tool rest; meanwhile, the support shaft rotates to screw the steel wire drawn out of the first wire box and the steel wire drawn out of the second wire box into a steel cable, so that the manufacture of the steel cable is realized; the first bracket, the second bracket and the transmission mechanism thereof are fixed on a large support plate of the lathe and move transversely along with the large support plate 1, and the steel cable forms a multi-strand spring on the winding mandrel. The invention can ensure that the core strand multi-strand cylindrical helical spring is twisted into the steel cable and wound with the spring to be formed at one time.
