Novel structural-steel bending deformation preventing device

Abstract

The invention provides a novel structural-steel bending deformation preventing device. The novel structural-steel bending deformation preventing device comprises a supporting base, a transverse supporting block, a first lifting body, a second lifting body, an upper deformation preventing wheel, a lower deformation preventing wheel and a driving roller. The bottom of the supporting base is installed in a horizontal sliding groove. The transverse supporting block is installed at the top of the supporting base. A vertical sliding groove is formed in one lateral side of the supporting base, and a horizontal lead screw is installed at the bottom of the other side of the supporting base. The first lifting body and the second lifting body are installed in the vertical sliding groove. A ball nut is fixed to the transverse supporting block through a fixing cover. A vertical lead screw penetrates through the ball nut to be connected with the first lifting body. The upper deformation preventing wheel and the lower deformation preventing wheel are connected with the lateral end of the first lifting body and the lateral end of the second lifting body respectively. The tail end of the horizontal lead screw is fixedly connected with a horizontal guiding fixing device. The outer side of the horizontal guiding fixing device is connected with an adjusting bolt. An upper positioning guide sleeve and a lower positioning guide sleeve are installed on the driving roller. A mold is installed between the upper positioning guide sleeve and the lower positioning guide sleeve. The novel structural-steel bending deformation preventing device is high in operability, good in working efficiency and high in machining quality.

Description

technical field [0001] The invention belongs to the technical field of profile cold-bending processing equipment, and in particular relates to a novel anti-deformation device for profile steel bending. Background technique [0002] The profile bending machine is a mechanical device that uses the principle of three-point fixed circle to bend the profile into a cylindrical, arc or spiral shape without basically changing the cross-sectional characteristics through the combination of molds and the rotational movement and lifting movement of the mold. Compared with stretch bending or bending metal profiles on a press, this equipment has the advantages of low price, simple operation, safety and reliability, and is widely used. The current general-purpose profile bending machine is equipped with correction devices on both sides, and can only correct the lower side of the H-shaped steel. The correction device moves along with the H-shaped steel in an arc. This type of steel bending ...

AI Technical Summary

Problems solved by technology

The current general-purpose profile bending machine is equipped with correction devices on both sides, and can only correct the lower side of the H-shaped steel. The correction device moves along with the H-shaped steel in an arc. This type of steel bending machine has the following problems: Sectional steel bending machine The correcting device is corrected after the H-shaped steel is deformed, which affects the mechanical properties of the H-shaped steel after bending; the correcting device moves along the arc with the H-shaped steel, and the transmission device is complicated. It is not easy to adjust for different H-shaped steels, and the correction after effect is not very good
