Description

Technical Field

[0001] The invention relates to the technical field of welding wire equipment, in particular to a flux-cored welding wire pay-off machine. Background Art

[0002] A flux-cored wire payoff machine is a device used to pay off a spool of flux-cored wire. A payoff unit typically consists of an adjustment frame, payoff components, and fixtures. The adjustment frame adjusts the distance between the payoff components; the payoff components are used to mount components like the wire spool and bearings; and the fixtures clamp the wire ends to prevent entanglement.

[0003] The current structure requires that when the wire reel is replaced, the wire reel needs to be lifted to the positioning height until the wire pay-off is connected to the wire reel, and the wire reel needs to remain lifted before being fixed.

[0004] Therefore, this solution provides a flux-cored wire pay-off machine, which can quickly and accurately position the wire reel by improving the existing pay-off machine, and the positioning process does not require maintaining a lifting state. Summary of the Invention

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 2 The flux-cored welding wire pay-off machine includes a holding box 1 for holding a wire reel 5. The front side of the holding box 1 is open, which is convenient for taking and placing the wire reel 5. At the same time, notches 13 are opened on the upper and lower walls of the front opening of the holding box 1. The notch 13 is set so that the distance between the rear wall of the notch 13 and the rear wall of the holding box 1 is smaller than the diameter of the wire reel 5, thereby facilitating the application of force to take and place the wire reel 5.

[0039] A group of conical heads 4 are distributed above and below the holding box 1 through a linkage mechanism 3. The conical heads 4 are rotatable, and holes 11 for the conical heads 4 to pass through are opened on the top and bottom walls of the holding box 1 opposite the conical heads 4. The two groups of conical heads 4 enter the holding box 1 from the upper and lower groups of holes 11 respectively and are inserted into the holes of the welding wire reel 5 placed in the holding box 1. Since the diameter of the large end of the conical head 4 is larger than the hole, the two groups of close conical heads 4 can clamp the welding wire reel 5 and provide support for the welding wire reel 5, so that the welding wire reel 5 is suspended in the holding box 1, thereby realizing rapid positioning of the welding wire reel 5.

[0040] See also Figure 1 、 Figure 4 and Figure 7The flux-cored welding wire pay-off machine has horizontal frames 2 fixed on the outer walls of both sides of the holding box 1, and sliders 21 slide in the horizontal frames 2. The linkage mechanism 3 includes a top plate 31 and a bottom plate 32 located above and below the holding box 1. The bottom plate 32 is used to support the pay-off machine as a whole, and linkage rods 33 are hingedly connected between the top plate 31 and the two groups of sliders 21 on both sides, and between the bottom plate 32 and the two groups of sliders 21 on both sides. The linkage rods 33 are always in an inclined state, and a telescopic rod 22 is fixed in the horizontal frame 2, which is fixed to the corresponding slider 21 in the horizontal frame 2 through the telescopic end of the telescopic rod 22, which is used to control the movement of the slider 21. The two groups of sliders 21 are used to approach or move away from each other to control the distance between the top plate 31 and the bottom plate 32, thereby controlling the synchronous adjustment of the distance between the top plate 31, the bottom plate 32 and the holding box 1.

[0041] The two groups of conical heads 4 are rotatably connected to the top plate 31 and the bottom plate 32 respectively, so as to control the two groups of conical heads 4 to synchronously approach or move away from the containing box 1.

[0042] See also Figure 1-Figure 7 , flux-cored wire pay-off machine, while the rear wall of the containing box 1 is provided with a rear window 12 for the end of the welding wire on the wire reel 5 to extend;

[0043] Extension plates 6 are fixed to the rear ends of the top plate 31 and the bottom plate 32. At the same time, the rear ends of the two groups of extension plates 6 are bent and approach each other, and the bent ends are located behind the rear window 12. Pressure rollers 61 are rotatably installed at the ends of the extension plates 6 that approach each other. When the top plate 31 and the bottom plate 32 approach each other, the two groups of pressure rollers 61 also approach each other. After the two groups of conical heads 4 are inserted into the holes of the welding wire reel 5 and clamp the welding wire reel 5, the two groups of pressure rollers 61 can clamp the end of the welding wire extending from the rear window 12;

[0044] On the one hand, the positioning of the welding wire reel 5 and the positioning of the welding wire end can be completed simultaneously; on the other hand, when the top plate 31 and the bottom plate 32 move away from each other, the two sets of pressure wheels 61 also move away from each other, avoiding obstruction of the rear window 12 and facilitating the extraction of the welding wire end.

[0045] See also Figure 5 , flux-cored welding wire pay-off machine, the rear part of the holding box 1 is an arc-shaped one adapted to the size of the welding wire reel 5, so that the welding wire reel 5 pushed into the holding box 1 can automatically achieve preliminary positioning when it contacts the arc-shaped rear wall, that is, at this time, the hole 11 is facing the coil hole of the welding wire reel 5;

[0046] An auxiliary wheel 7 is rotatably provided in a groove on the rear wall of the storage box 1 , and one side of the auxiliary wheel 7 extends from the groove into the storage box 1 for friction-reducing contact with the welding wire reel 5 .

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
