Solid wire winding assembly for arc welding

Abstract

The present invention relates to an arc welding used solid welding stick coiling assembly which improves the coiling state. The arc welding used solid welding stick coiling assembly according to the invention is provided with the following components: a columnar heart part; a bobbin skeleton framing and the flanges are provided at the two sides of the heart part; and a arc welding used solid welding stick which coils the skeleton framing, it is characterized in that the void percentage of the arc welding used solid welding stick coiled on the bobbin skeleton framing ranges from 11.5 to 15.5 in order to prevent that it is clamped between the arc welding used solid welding stick coiled at the lower side; wherein, the avoid percentage (%)=((Va-Vb) / Va)*100; Va: surface volume of the coiled solid welding stick; Vb: the actual volume of the coiled solid welding stick.

Description

technical field [0001] The invention relates to a solid welding wire winding assembly for arc welding, in particular to a solid welding wire winding assembly for arc welding with improved winding state. Background technique [0002] Recently, with the semi-automation or full automation of welding, the demand for solid wire for arc welding is also increasing. Solid wire for arc welding is widely used in steel skeleton, automobile, shipbuilding, building materials industry and other fields. These solid wires for arc welding have some differences in their manufacturing process depending on whether the surface is copper-plated or not, but they are all wound on a bobbin and then passed through a packaging process. [0003] Among them, the above-mentioned winding process is divided into large-capacity pail pack winding and light-weight spool bobbin winding. The spool bobbin winding is used to improve the supply of welding wire that is directly related to welding quality. (supply...

Problems solved by technology

[0006] First, in the winding process, there is a gap between the solid-core welding wire wound on the bobbin skeleton, and a part of the solid-core welding wire wound on its upper part is caught in the gap between the solid-core welding wire of the lower winding layer, resulting in winding Disorderly alignment, resulting in irregular alignment of the solid wire wound on top

[0007] Second, even if the solid core wire is neatly wound on the bobbin frame in the winding process, a part of the wound solid core wire is deeply sunken into the lower coil due to impact or the like during the transfer process after the packaging process. Between the solid wires of the winding layers, resulting in the disorder of the neat winding arrangement

[0008] Third, the enhancement of the angle and strength of the flange of the bobbin skeleton has a slight effect on the phenomenon that the solid core welding wire sinks into the lower winding layer, but the clamping force of the sunk solid core welding wire is relatively large, so it will Phenomena that lead to poor supply of solid wire

[0009] Fourth, because the winding arrangement of these solid-core welding wires is disturbed, friction occurs between the solid-core welding wires, and there is also the problem of leaving flaws on the surface of the solid-core welding wires

In addition, the solid wire is caught in the lower winding layer, and there are also welding failures such as a decrease in the supply of the solid wire during welding, and meandering of the welding bead.
