Abstract

The invention discloses a cold roll forming device and method of T-shaped reinforcing ribs of a large spherical tank. The device comprises a plate rolling machine and supporting discs. The plate rolling machine comprises an upper roller, a pair of lower rollers and a driving mechanism. The lower rollers are arranged on the two sides below the upper roller. The driving mechanism is used for drivingthe upper roller to reciprocate up and down and pressurizing and loading the upper roller. The two lower rollers are sleeved with the two supporting discs. Grooves are formed in the portions, close to the middle of the periphery of the upper roller, of the supporting discs in the circumferential directions, the groove widths of the grooves are consistent with the thickness of a web for forming T-shaped steel of the T-shaped reinforcing ribs, and the groove depths of the grooves are larger than the height of the web for the T-shaped steel. The finished T-shaped steel is directly formed by coldroll, the T-shaped reinforcing ribs are prepared, the cost can be greatly reduced, manufacturing procedures can be reduced, and the forming quality of the T-shaped reinforcing ribs is guaranteed.

Description

technical field [0001] The invention specifically relates to a cold-bending forming device and method for a T-shaped reinforcing rib of a large spherical tank. Background technique [0002] With the rapid development of China's science and technology and construction technology, large spherical tanks are more and more widely used in industry, such as figure 1 As shown, adding T-shaped ribs on the shell of the spherical tank is a very effective way to reduce the weight of large spherical tanks. Generally, adding T-shaped ribs to the outer surface or inner surface of the spherical tank can greatly increase the wall thickness of the spherical tank. decline. [0003] Such as figure 2 As shown, the traditional T-shaped stiffener is made by welding. First, the flange and web of the T-shaped rib are cut separately, then the flange is cold-bent with a plate rolling machine, and finally the flange and web are assembled. weld. This method has many manufacturing processes, large m...
