If the total lead S of the guide rod is too long, it will cause stacking of wires at both ends of the rewinding I-shaped wheel and the plate will rise; if the total lead S of the guide rod is too short, it will cause the wires at both ends of the rewinding I-shaped reel to be unsatisfactory, and the winding length will be fixed. Not enough; deflector commutation radius R 1 and guide rod commutation radius R 2 If the design is unreasonable, it will cause disordered lines at the rewinding I-shaped wheel

Embodiment Construction
[0070] The implementation of the present invention will be described in detail below in conjunction with the implementation cases, but they do not constitute a limitation to the present invention, and are merely examples. At the same time, the advantages of the present invention will become clearer and easier to understand.
[0071] The method for configuring the parameters of the wire guide rod pair of the double twister of the present invention includes the following steps:
[0072] 1) According to the winding wire diameter d, select the guide rod and its supporting guide; when the winding wire diameter d≥1mm, select the bidirectional double groove guide rod 1 (such as Figure 1~3 Shown) and two-way double groove guide 2 (as Figure 4~6 Shown), and select the bidirectional double-slot guide rod 1 to adopt rectangular thread; when the winding wire diameter d Figure 7 Shown) and two-way single slot guide 4 (as Figure 8-9 Shown), and select the bidirectional single-slot guide rod 3...

The invention discloses a double-twist machine winding displacement guide rod pair parameter configuration method. The method comprises the following steps that 1) according to the diameter d of a winding wire rod, a guide rod and a matched guider thereof are selected; 2) the total lead S of the guide rod is calculated; 3) the thread pitch p is calculated; 4) the guide rod large diameter d, guiderod intermediate diameter d2, guide rod small diameter d1 and thread width U are determined; 5) the lead angle psi is calculated; 6) the positive pressure F and strength P of the guider are calculated; 7) the row spacing h of the winding wire rod is calculated; 8) the reversing radius R1 of the guider and the reversing radius R2 of the guide rod are calculated; 9) three-dimensional modeling is performed according to the various determined dimension parameters of the guide rod and matched guider, and all the dimension parameters of the guide rod and matched guider are finally corrected according to three-dimensional verification results until the guide rod and the guider run flexibly without sticking. The winding displacement guide rod pair configured by the method has reasonable parameters, the wire rod winded by the designed winding displacement guide rod pair is uniform and orderly, no wire disorder or reel swelling exists after layer-by-layer winding and full winding, and the qualified rate of the twisted wire rod is greatly increased.
Description
Technical field [0001] The invention relates to the technical field of double-twisting machines, and in particular to a method for configuring the parameters of the wire guide rod pair of the double-twisting machine. Background technique [0002] Double twisting machine is a stranding production equipment of steel cord and steel wire rope. The wire guide rod pair is an important part of the double twisting machine equipment, including guide rods and guides. Its working principle is generally to drive the twisting by the reciprocating motion of the guide rod pair. The prepared wire is wound between the spans of the spool. If the total lead S of the guide rod is too long, it will cause the winding spool to pile up and expand the coil; if the total lead S of the guide rod is too short, it will cause the wire row at both ends of the winding spool to be dissatisfied and the winding length will be fixed. Not enough; director commutation radius R 1 And guide rod commutation radius R 2 ...
