Description

Technical Field

[0001] The utility model relates to the technical field of steel plate cutting and feeding, in particular to a steel plate cutting and feeding device for bridge construction. Background Art

[0002] When processing special-shaped bridge structures, the diaphragm or web needs to be welded with longitudinal stiffeners. Since there are many types of longitudinal stiffener parts in different lengths, in the production process of longitudinal stiffeners, the usual practice is to use longitudinal ribs to cut the steel plate according to the strip drawing, and then use a cutting machine to cut the steel plate. The production of longitudinal stiffeners is mostly completed in the steel plate cutting workshop.

[0003] However, the existing steel plate cutting and feeding device for bridge construction still has some shortcomings. It is necessary to use an overhead crane to lift the steel plate onto the workbench of the cutting machine. Due to the relatively small space of the cutting machine, the position of the steel plate loading cannot be adjusted by direct lifting, and the steel plate cutting position cannot be aligned with the cutting position, which reduces the accuracy of steel plate cutting. In addition, it is inconvenient to effectively fix the steel plate during cutting, which easily causes the steel plate to move during cutting, thereby reducing the cutting quality. Therefore, we propose a steel plate cutting and feeding device for bridge construction to solve the above problems. Utility Model Content
