A mold for stabilizing the welding quality of optical fiber stainless steel casing

Abstract

The invention discloses a mold for stabilizing the welding quality of optical fiber stainless steel sleeves. The mold comprises a cylinder; a connecting ring and a connecting groove are respectively arranged at the two ends of the cylinder; a fastening bolt is mounted at one end of the cylinder, and is inserted in the connecting groove; an opening groove is formed in the outer side of the cylinder; slide rail grooves are formed in the two sides of the opening groove; stop devices are slidingly mounted in the slide rail grooves, and are connected with one end of the opening groove through tension springs; and a limiting block is arranged at the other end of the opening groove. The mold has the following beneficial effects: self elasticity of the tension springs is used for cooperating withlifting of stop rods to apply resistance to wound steel strips, so that gaps are adjusted, unified gap sizes are guaranteed, and the welding line quality is guaranteed; the splicing installation of devices can be realized through the connecting ring and the connecting groove; and the devices are freely combined according to the lengths of sleeves to meet production of the sleeves with different lengths.

Description

technical field [0001] The invention relates to the technical field of production auxiliary devices for optical fiber stainless steel sleeves, in particular to a mold for stabilizing the welding quality of optical fiber stainless steel sleeves. Background technique [0002] The existing optical fiber stainless steel casing involving optical fiber composite overhead phase wire or optical fiber composite overhead ground wire is formed by curling a steel strip through forming rollers into a tube, and then fusing the longitudinal seams by laser welding. [0003] The applicant found that there are at least the following technical problems in the prior art: after the steel strip is crimped and formed, there are large gaps, and the gaps are of different sizes, and the weld quality is likely to be unstable after welding. Contents of the invention [0004] The object of the present invention is to provide a mold for stabilizing the welding quality of optical fiber stainless steel c...
