Stretching device for producing welding wire

Abstract

The invention relates to the technical field of welding wire production, in particular to a stretching device for producing a welding wire. The stretching device comprises a shell, wherein a conical roller connected between the inner walls of the two sides of the shell through bearings, an elliptical roller is connected between the inner walls of the two sides of the shell through bearings, a second stretching roller is connected between the inner walls of the two sides of the shell through bearings, and an embossing roller is connected between the inner walls of the two sides of the shell through bearings; one end of the conical roller, one end of the elliptical roller, one end of the second stretching roller and one end of the embossing roller extend out of the shell to be connected with transmission wheels through flat keys; every two adjacent transmission wheels are in transmission connection through a belt; and the outer wall of one side of the shell is connected with a first motor through a bolt. The welding wire is wound on the elliptical roller, the second stretching roller and the embossing roller, so that the linear speeds generated when a first stretching roller, the second stretching roller and the embossing roller rotate are different, the effect that the welding wire is gradually stressed and stretched is achieved, the stress is uniform, and the welding wire is not prone to being snapped.

Description

Technical field [0001] The present invention relates to the field of wire production technology, in particular for producing wire drawing apparatus. Background technique [0002] Wire is usually wound on the spool, as a filler metal solder material, widely used in metal welding process, the wire needs to be relatively large diameter wire drawing process in the production process, so that the wire diameter to be changed, to meet the use of welding. [0003] Chinese patent No. 201610045601.3 discloses a method of stretch-forming apparatus and a tin-bismuth alloy wire, tin-bismuth alloy ingot through a drawing die assembly in the die holder from the inlet of the mold into the base and extending from the outlet of the die holder , achieved by drawing stretch forming machine. [0004] Production prior art wire stretching means stretching the wire, the wire discontinuity, leading to wire easily pulled off in the production process, and during the wire drawing, the wire drawing extended...
