They help to achieve first-in-first-out of goods, improve selection capabilities and inventory turnover, and the interior of the shelf contains support arms. The support arms are also known as horns, which are metal parts that support the shelves at the left and right ends under the shelf shelves. During the processing of the support arms, the vertical pipes need to be welded to the bottom plate, so the support arm blocking plate welding device is needed.

[0004] However, this bracket welding fixture has the following disadvantages:

[0005] (1) During the welding of the shelf support arm, the support arm needs to be welded to the structural parts of the shelf, but the support arm and the structural parts cannot be fixed at the same time, and the welding point is close, which reduces the welding efficiency;

[0006] (2) A large amount of smoke will be generated during welding, but the smoke cannot be concentrated in the same direction, so the smoke directly faces the welder, affecting the welding process. Utility Model Content
