Welding wire container and method of making the same

Abstract

A container for packaging and unwinding a welding wire having a natural cast that is essentially a straight line. The container including a box with vertical side walls each having an inner wall surface and vertically extending corners between the side walls, a closed bottom, a top opening for removing the welding wire. The container further including a first vertically extending cylindrical liner with a first radial outwardly facing surface and a first radial inwardly facing surface wherein the first inward surface has a diameter A and is coaxial with a vertically extending container axis such that the first liner is supported by the side walls. The container further includes a second cylindrical liner having a second radial outwardly facing surface and a second radial inwardly facing surface. The second outward surface having a diameter B that is less than diameter A and is coaxial with the axis. The second outward surface defining a radial inward extent of an annular wire cavity and the first inward surface defines a radial outward extent of the annular wire cavity. The container also including a wire coil made up of a plurality of convolutions of the wire. Each of the convolutions having a similar effective convolution diameter that is greater than fifty percent of diameter A but less than diameter A. The natural cast producing a radially outward force in the each convolution that is supported by the first liner and the coil extending radially between the first and second liners.

Description

technical field [0001] The present invention relates to a welding wire package, in particular to a welding wire package converted from a square or polygonal package, which is used as a welding wire reel and can be used in conjunction with the design of the braking device of the welding wire reel. Background technique [0002] Welding wire used in high production operations, such as on automated welding stations, is placed in bulk packages with over 200 pounds of welding wire. The wire in this package is wound into a wire coil coil configuration, forming a coil around a central core or central clearance hole. A restraint mechanism can be used to prevent movement of the wire coil and center core during transport. To control the transport and release of the welding wire, an upper retainer or braking device, such as a brake ring, may be used to help control the unwinding of the welding wire from the coil. One such package is shown in Cooper's 5,819,934 patent, which discloses ...

AI Technical Summary

Problems solved by technology

This can cause damage to the wire spool and potential damage to the wire due to minor contact between adjacent wire spools or other objects

We can also note that damage to the wire can cause deformation of the wire, adversely affecting the process of feeding the wire out of the package and through the wire dispenser and / or wire torch
