Problems solved by technology

[0003] In the prior art, the medium-shaped steel cold bending machine is gradually deformed one by one through the transmission of the lower roller. Because the rolled-out steel is driven by a single roller, the speed ratio will be poor, and the friction on both sides is large. The product cannot be controlled in the pass. Scratches and strains on the fish scales on the edge, displacement of the roll printing line, and short straight lines

Abstract

The invention discloses a four-roller synchronous deformation mechanism of a profile steel forming mill, and relates to metal proximate matter forming mills. The mechanism comprises frame type supports which are arranged in a bilateral symmetry mode, lower roller supports and upper roller supports are symmetrically arranged in the frame type supports on the two sides respectively, power lower rollers and unpowered upper rollers are arranged between the frame supports on the two sides, the middles of the upper ends of the upper roller supports of the frame type supports on the two sides are respectively and fixedly connected with a first vertical lead screw, the first lead screws penetrate through the frame type supports upwards respectively, side roller frames are symmetrically fixed to the outer sides of the lower roller supports on the two sides, side roller bases are arranged on the lower roller supports on the two sides respectively, side rollers are axially positioned at the inner side ends of the side roller bases, and the middles of the outer side ends of the side roller bases are respectively and fixedly connected with a second horizontal lead screw. Through improvement and innovation, the quality is greatly improved, the base plate of the product is flat, scratching and scale damage cannot happen to the two side portions, stretching is avoided, a roller printing line is not displaced, and the linear face is long.

Description

technical field [0001] The invention relates to a metal profile cold bending machine, in particular to a four-roller synchronous deformation mechanism of a profile steel cold bending machine. Background technique [0002] Compared with hot-rolled products, cold-formed steel has reasonable geometric shape, beautiful appearance and light weight. Any shape that cannot be rolled by hot-rolled products can be designed by cold-rolled section steel through reasonable design. [0003] In the prior art, the medium-shaped steel cold bending machine is gradually deformed one by one through the transmission of the lower roller. Because the rolled-out steel is driven by a single roller, the speed ratio will be poor, and the friction on both sides is large. The product cannot be controlled in the pass. Scratches and strains on the fish scales on the edge, displacement of the roll printing line, and short straight lines. Contents of the invention [0004] The object of the present inve...
