Problems solved by technology
According to the traditional process, the U rib is first bent and formed, and then the two sides are milled or planed separately. Not only the deformation is large, the product consistency is not enough, but also the efficiency is low, and the quality is difficult to guarantee.

The invention relates to a non-equal-thickness U-rib production line and belongs to the technical field of steel structure production equipment. The non-equal-thickness U-rib production line comprises multiple forming units (1), a centering unit (2), a first centering unit (3), a flattening unit (4), a second centering unit (5), multiple bending units (6), multiple shaping units (7) and a saw cutting unit (8) which are sequentially arranged front the front to the back. The non-equal-thickness U-rib production line directly extrudes the two ends of a board to be in a groove shape, then bending, shaping and saw cutting are conducted, the milling or planing procedure is eliminated, and the production efficiency is improved. In addition, a finally finished product is in a more reasonable non-equal-thickness shape, the welding area is increased, and the welding quality of U ribs is improved conveniently.
Description
technical field [0001] The invention relates to a non-uniform thickness U-rib production line, which belongs to the technical field of steel structure production equipment. Background technique [0002] The manufacture of steel structures and its application in the construction industry has been rapidly developed, and has been widely used in factories, warehouses, gymnasiums, exhibition halls, supermarkets, multi-storey buildings and large-span structural buildings. The development of U ribs on steel bridge decks has also been greatly developed. In recent years, with the increase of investment in domestic infrastructure construction, the construction of steel structure bridges has flourished. The key to the construction of steel structure bridges lies in the application of long-span steel structure bridge deck girders. The domestic steel structure bridge manufacturing industry lacks special equipment, and the lack of auxiliary equipment in some auxiliary processes is common...
