Description

Technical Field

[0001] The utility model relates to the technical field of storage rack processing, and particularly relates to a welding feeding device for storage racks. Background Technique

[0002] Racks are important tools for warehouse modernization and efficiency improvement, and the market demand share is getting higher and higher. Storage racks usually have three major accessories: columns, crossbeams, and shelves. This refers to heavy-duty, medium-duty, and light-duty storage racks. For super-heavy-duty and attic storage racks, columns and crossbeams are mostly used as accessories. Connection pieces need to be welded at both ends of the columns. When the connection pieces are connected with screws, it is convenient for the storage racks to be assembled. Currently, two welding devices are used to weld both sides of the columns simultaneously.

[0003] For example, the Chinese patent with the authorization announcement number CN220427258U discloses a feeding device for steel pipe welding, which includes a feeding base. One end of the feeding base is provided with a lifting groove, one end of the lifting groove is provided with a hydraulic cylinder, and one end of the hydraulic cylinder is provided with a material receiving pipe groove.

[0004] The above-mentioned feeding device for welding has the advantage of adapting to different lengths of steel pipes; however, the above-mentioned feeding device for welding and the commonly used feeding devices in the market still have some disadvantages. For example: First, the feeding efficiency is low and the positioning effect is poor. The welding columns are directly placed on the feeding device, and it is easy to collide during the conveying process, resulting in the deviation of the feeding position and affecting the feeding speed; Second, the columns cannot be quickly sent to the welding station. Some columns need to be manually adjusted due to position deviation, which takes time during the adjustment process and affects the processing efficiency of the welding equipment.
