Description

Technical Field

[0001] The utility model relates to the technical field of cored wire production, in particular to a welding device for seamless cored wire production. Background Art

[0002] Core-clad wire is a composite material made by crushing various additives (such as deoxidizers, desulfurizers, modifiers, and alloys) to be added to molten steel or iron into a specific particle size. This material is then wrapped with cold-rolled low-carbon steel strip to form a strand of composite material of any length. Currently, the most commonly used core-clad wire manufacturing method in China is the undercut method. However, this method fails to hermetically seal the internal powder from the outside air. As a result, after a period of use, the powder in the alloy core-clad wire easily reacts with oxygen and water vapor in the air, causing deterioration and affecting the wire's usability. Patent application number 201310462956.9 discloses a core-clad wire laser welding method. While this method isolates the internal material of the core-clad wire from the outside air, the groove spacing during welding is large, and the grooves are not treated before welding. This results in high welding material consumption, large welds, and long welding times. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a welding device for seamless cored wire production with high welding efficiency and small gap.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows: the welding device for seamless cored wire production includes a welding gun mechanism and a flattening assembly located upstream of the welding gun mechanism, wherein the welding gun mechanism includes a bracket, a support arm arranged on the bracket, and a welding gun body arranged on the support arm.

[0005] The flattening assembly includes a first pressure wheel assembly facing the splicing groove of the cored tube, a second pressure wheel assembly arranged on the side close to the welding gun mechanism, and a conveying roller arranged between the first pressure wheel assembly and the second pressure wheel assembly. The second pressure wheel assembly includes at least three pressure wheels, and the three pressure wheels form a conveying channel for the cored tube to pass through.

[0006] Furthermore, the first pressing wheel assembly includes a first upper pressing wheel and a first supporting wheel, and the first upper pressing wheel is directly opposite to the splicing groove of the cored tube and flattens the splicing groove.

[0007] Furthermore, the first supporting wheel is arranged directly below or obliquely below the first upper pressing wheel.

[0008] Furthermore, the first pressure wheel assembly also includes a first bracket, the first bracket includes a fixed plate, an adjustment plate connected to the fixed plate and a locking bolt for locking the position of the adjustment plate and the fixed plate, and the first upper pressure wheel is connected to the adjustment plate.

[0009] Furthermore, the second pressing wheel assembly includes a second upper pressing wheel and a second side pressing wheel arranged in a pair, and a gap between the second upper pressing wheel and the second side pressing wheel constitutes the transmission channel.

[0010] Furthermore, a second supporting wheel is provided directly below the second upper pressing wheel.

[0011] Furthermore, the second pressure wheel assembly also includes a second bracket, the second bracket includes a column and a convex column spaced apart on the column, the second side pressure wheel is arranged between the two convex columns, and the second upper pressure wheel is connected to the two convex columns at the upper end.

[0012] Furthermore, it also includes claws arranged on the front and rear sides of the welding gun body and a fixed electrode arranged between the claws, and the claws are provided with arc grooves adapted to the core tube for the core tube to pass through.

[0013] In this welding device for seamless cored wire production, the steel strip is closed after being rolled multiple times. At this point, the first pressure roller assembly performs the first rolling of the spliced groove, flattening the groove. The second pressure roller assembly then straightens the formed cored tube and the groove position. The cored tube is then conveyed along the production line to the bottom of the welding gun mechanism for welding. This welding device for seamless cored wire production employs a pre-rolling and flattening process before welding. This can result in smaller weld seams, tighter spliced grooves, reduced welding material usage, and effectively shortened welding time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0024] like Figure 1-6 As shown, a welding device for seamless cored wire production includes a welding gun mechanism and a flattening assembly located upstream of the welding gun mechanism. The welding gun mechanism includes a bracket, an arm disposed on the bracket, and a welding gun body disposed on the arm.

[0025] The flattening assembly includes a first pressure wheel assembly 1 facing the splicing groove of the cored tube, a second pressure wheel assembly 2 arranged on the side close to the welding gun mechanism, and a conveying roller arranged between the first pressure wheel assembly 1 and the second pressure wheel assembly 2. The second pressure wheel assembly 2 includes at least three pressure wheels, and the three pressure wheels form a conveying channel for the cored tube to pass through.

[0026] In this welding device for seamless cored wire production, the steel strip is closed after being rolled multiple times. At this time, the first pressure roller assembly 1 performs the first rolling of the spliced groove to form a flat shape at the closing position. The second pressure roller assembly then corrects the entire formed cored tube and the groove position. The cored tube is then conveyed along the production line to the bottom of the welding gun mechanism for welding. The present welding device for seamless cored wire production is provided with a pre-process of rolling and flattening before welding. This can make the weld seam smaller, while at the same time making the spliced groove bite more tightly, reducing the use of welding materials and effectively shortening the welding time.

[0027] The first pressing wheel assembly 1 includes a first upper pressing wheel 11 and a first support wheel 12. The first upper pressing wheel 11 faces and flattens the groove of the cored tube. In this embodiment, the first support wheel 12 is positioned directly below or diagonally below the first upper pressing wheel 11. The first support wheel 12 cooperates with the first upper pressing wheel 11 to apply force, thereby achieving an optimal flattening operation and ensuring smooth transportation of the cored tube.

[0028] Taking into account the force exerted by the first upper pressure wheel 11 on the core tube and the wear after later use, the first pressure wheel assembly 1 also includes a first bracket, which includes a fixed plate 14, an adjustment plate 15 connected to the fixed plate 14, and a locking bolt 13 for locking the position of the adjustment plate 15 and the fixed plate 14. The first upper pressure wheel 11 is connected to the adjustment plate 15, and a better pressure value can be obtained by adjusting the first upper pressure wheel 11.

[0029] The second pressure roller assembly 2 includes a second upper pressure roller 21 and a second side pressure roller 24 arranged in a pair. The gap between the second upper pressure roller 21 and the second side pressure roller 24 constitutes the transmission channel. In order to prevent the cored tube from being over-pressed at the first upper pressure roller 11, a second pressure roller assembly 2 for correction is provided downstream of the first pressure roller assembly 1 to control the entire cored tube. In this embodiment, a second support wheel 22 is further provided directly below the second upper pressure roller 21. The second pressure roller assembly 2 also includes a second bracket. The second bracket includes a column 23 and a protrusion spaced apart on the column 23. The second side pressure roller 24 is provided between the two protrusions. The second upper pressure roller 21 is connected to the two protrusions at the upper end.

[0030] In order to achieve smooth transmission of the cored tube and convenient welding, it also includes support claws 3 arranged on the front and rear sides of the welding gun body and a fixed electrode 4 arranged between the support claws 3. The support claws 3 are provided with an arc groove adapted to the cored tube for the cored tube to pass through.

[0031] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
