AI Technical Summary

Benefits of technology

This configuration reduces the required compressive force needed to drive the wire, minimizing deformation and wear on the mechanism, while enhancing the mechanical advantage for better wire engagement and reduced slippage.

Problems solved by technology

As a result of this arrangement, the compressive forces exerted on the wire by the driver rollers often cause the wire to undesirably deform.

Embodiment Construction

[0023] Referring now to the drawings wherein the showings are for purposes of illustrating one or more preferred embodiments of the invention only and not for purposes of limiting the same, FIG. 1 shows a wire feeding mechanism 10 having a wire pathway 12 defined in part by wire support guides 14,16. The wire feeding mechanism 10 is generally situated between a bulk supply of wire 18 and a workpiece 20. The wire 18 extends from the bulk supply, shown as roll 22 inFIG. 1, to the wire feeding mechanism 10, and further extends to the workpiece 20 where it is consumed in the process of welding. The wire 18 can be alternatively supplied in a wide variety of other bulk forms, including for example boxes, reels and the like.

[0024] Generally, a flexible conduit 24 extends from the mechanism 10 on a downstream side 26 thereof such that the wire 18 will be advanced by the mechanism 10 through the conduit 24 to a welding gun 28 adjacent the workpiece 20. As the mechanism 10 axially advances t...

Abstract

A wire feeding mechanism for advancing a continuous length of wire along a pathway includes a housing having two roller supports each rotatable about a corresponding axis transverse to a wire pathway. The roller supports are on opposite sides of the pathway and are driveably engaged with each other. A drive roller is on each of the roller supports for rotation therewith. The drive roller includes an outer surface extending circumferentially about the corresponding axis. The outer surface defines a groove having an included angle of less than ninety degrees (90°). The drive roller on each of the roller supports compressively contacts a continuous length of wire between the roller supports such that the wire is advanced along the pathway in response to rotation of the drive rollers.

Description

[0001] This application is a continuation of U.S. application Ser. No. 10 / 800,929, filed Mar. 15, 2004, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to the art of wire feeding mechanisms and, more particularly, to drive rollers used in wire feeding mechanisms for driveably advancing a welding wire. The present invention finds particular application in conjunction with drive rollers used to advance a welding wire and will be described with particular reference thereto. It is to be appreciated, however, that the present invention may relate to other similar environments and applications. [0004] 2. Discussion of the Art [0005] U.S. Pat. No. 6,557,742 to Bobeczko et al., U.S. Pat. No. 5,816,466 to Seufer and U.S. Pat. No. 4,235,362 to Hubenko, all expressly incorporated herein by reference, disclose wire feeding mechanisms and provide general background information related th...
