The invention discloses a forming method of a contact wire. The forming method comprises the following steps that S1, a raw material wire rod is loaded into an uncoiler; S2, the raw material wire rod is corrected and straightened through a straightening device to obtain a straightened wire rod; S3, the straightened wire rod is subjected to roller drawing deformation through a roller drawing die device, and the finished contact wire of a preset specification is obtained; and S4, the finished contact wire is coiled by a coiling machine. By means of the forming method, the large-length, high-strength and high-conductivity contact wire is formed in a roller drawing mode, the drawing force is reduced by about 2/3 when a roller drawing die is used for drawing the contact wire at the same deformation, the drawing force in the drawing process is greatly reduced, the forming speed is increased, the service life of a grinding tool is prolonged, the surface quality of the contact wire is improved, the problems that an original drawing die of the high-strength contact net wire is short in service life, low in production efficiency and poor in surface quality of the contact net wire due to large deformation resistance of a high-strength line blank are solved, and the quality requirement of the high-strength and high-conductivity contact net wire is met.

    本发明公开了一种接触线的成型方法,包括如下步骤:S1:将原材料线材装入开卷机;S2:原材料线材经矫直装置进行矫正拉直得到拉直线材;S3:拉直线材经辊拔模装置进行辊拔变形,得到预设规格的成品接触线;S4:卷取机卷取成品接触线。本发明采用辊拔方式形成大长度高强高导接触线,辊拔模具拉拔接触网线同变形量拉拔力降低了约2/3,大幅度降低了拉拔过程中的拉拔力,成型速度得到提高,提高了磨具寿命,且接触线表面质量得到提高,解决了高强度接触网线原拉拔模具因高强线坯变形抗力大使拉拔模寿命低,生产效率低,接触网线表面质量差的问题,满足高强高导接触网线的质量要求。
