Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to an automatic submerged arc welding flux laying device adapted for a lithium battery welding trolley. Background Art

[0002] As a common welding method in the field of ship welding, carbon dioxide gas shielded welding has been widely used in production. In order to improve welding stability and production efficiency, lithium battery welding carts adapted to it have also been widely developed and applied. However, there is a bottleneck in the welding efficiency of carbon dioxide gas shielded welding, and the welding spatter and smoke are large, and the working conditions are general. Submerged arc welding, as an automatic, efficient welding method with a good welding environment, has also been widely used. Submerged arc welding is commonly used for welding thicker ship plates. Its heat input is greater than that of carbon dioxide gas shielded welding, and the deformation after welding is also greater. There are many thin plates in the PCTC and other ship types built by the company. Therefore, in order to control deformation and reduce heat input, it is necessary to develop a fine wire submerged arc welding process, which has simultaneously met the technical requirements of high welding efficiency, good production environment and small deformation after welding.

[0003] With the successful development and promotion of welding technology, we have received good feedback from the site. However, as the promotion deepens, we find that the main automatic welding equipment in the field of loading and unloading is carbon dioxide gas shielded welding lithium battery car. If it is promoted, it is necessary to re-purchase submerged arc welding equipment, which will increase the cost to a certain extent.

[0004] When using the lithium battery trolley for submerged arc welding, we found that since the lithium battery trolley does not have a submerged arc welding flux box like the common submerged arc welding trolley, the submerged arc welding flux needs to be manually laid on the welding path continuously during the welding process. This operation is contrary to the automation requirements of the process and wastes manpower; manual laying of flux often cannot control the dosage and causes flux waste. Therefore, a flux box is needed to cooperate with the lithium battery trolley to enable it to perform welding operations like normal submerged arc welding. Summary of the invention

[0005] In order to solve the technical problems existing in the prior art, the present invention provides an automatic submerged arc welding flux laying device adapted to a lithium battery welding trolley, comprising a flux box, which is detachably connected to the lithium battery trolley; the flux box is used to carry submerged arc welding flux, and the lower end of the flux box is provided with an opening with a switch for transporting the submerged arc welding flux to the position of the welding gun.

[0006] Furthermore, a filter screen is installed on the top of the flux box.

[0007] Furthermore, the flux box is connected to the lithium battery trolley via a bracket, and the flux box and the bracket are connected by bolts.

[0008] Furthermore, the body of the bracket is rigid, and its shape and tooling can be adaptively adjusted according to different models of lithium battery carts.

[0009] Furthermore, the opening at the lower end of the flux box is connected to a hose via a connecting sleeve.

[0010] Furthermore, a Velcro strap is provided at the end of the hose away from the flux box and is fixed in front of the welding gun before welding.

[0011] Furthermore, the lithium battery welding trolley is provided with a connecting seat, and the bracket is provided with a plurality of connecting heads that cooperate with the connecting seat; the connecting heads and the connecting seat are made of ferromagnetic materials that cooperate with each other.

[0012] Furthermore, the end of the hose away from the flux box is provided with an adsorption head capable of being adsorbed on the bracket.

[0014] The present invention can automatically lay flux without manual work, thus improving efficiency and saving manpower; the equipment has a simple structure, and after application, it can reduce the equipment investment in new submerged arc welding machines and save costs; it is easy to disassemble and meet the application scenarios of lithium battery vehicles for different welding methods; it expands the application scope of submerged arc welding, improves welding efficiency, improves welding quality, and reduces the labor intensity of welders.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-Figure 2 The automatic laying device for submerged arc welding flux adapted to a lithium battery welding trolley proposed in this application includes a flux box, which is detachably connected to the lithium battery trolley; so that the device can also achieve the effect of automatically laying flux during submerged arc welding.

[0027] like Figure 3 and 4 The flux box is used to carry submerged arc welding flux. An opening with a switch is provided at the lower end of the flux box for conveying the submerged arc welding flux to the welding gun. A filter is installed on the top of the flux box to prevent debris from entering the opening at the bottom and affecting the delivery of the flux.

[0028] like Figure 5 and 6 The flux box is connected to the lithium battery trolley through a bracket, and the flux box and the bracket are connected by bolts. The body of the bracket is rigid, and the shape and tooling can be adaptively adjusted according to different models of lithium battery trolleys.

[0029] like Figure 7-10 The opening at the lower end of the flux box is connected to a hose through a connecting sleeve. The hose is used to transport the flux in the flux box to the welding gun position of the welding carriage and can meet different welding direction requirements.

[0030] In some embodiments of the present application, a Velcro strap is provided at the end of the hose away from the flux box and is fixed in front of the welding gun before welding for easy disassembly.

[0031] In other embodiments of the present application, a connection seat is provided on the lithium battery welding trolley, and a plurality of connection heads cooperating with the connection seat are provided on the bracket; the connection heads and the connection seat are made of mutually cooperating ferromagnetic materials. The end of the hose away from the flux box is provided with an adsorption head that can be adsorbed on the bracket, which is convenient for storing the hose. In certain emergency situations, the delivery of the flux can be forcibly stopped by raising the position of the end of the hose.

[0032] In some other embodiments of the present application, a self-balancing component is installed between the bracket and the flux box; after the self-balancing component is installed, the center of gravity of the flux box is located below the connection between the flux box and the bracket; at the same time, the opening position of the bottom of the flux box is adjusted to be located below the plane where the bottom of the flux box is located; under this double guarantee, within a certain range, the flux box's transportation of flux is not affected by the connection posture and welding posture, thereby improving its scope of application.

[0033] In summary, the above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereto. All equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification are within the scope covered by the patent of the present invention.
