Problems solved by technology

In the straightening of the rebar, if this method is also used, although the installation directions of the horizontal wheel and the vertical wheel are different, the rebar will be twisted 90 degrees during the movement, and the horizontal wheel and the vertical wheel are finally pressed against the rebar. On the two longitudinal ribs, the required straightening of two different surfaces actually acts in the same direction, and it is impossible to straighten the rebar in a true sense.

Abstract

The invention discloses a threaded steel straightening device and a straightening method. The threaded steel straightening device comprises a feeding mechanism which is suitable for clamping threaded steel in the vertical direction and used for conveying the threaded steel in the horizontal direction, and further comprises a first straightening mechanism, a second straightening mechanism and a third straightening mechanism which are sequentially arranged in the conveying direction of the feeding mechanism, wherein the first straightening mechanism is suitable for clamping the threaded steel in the vertical direction and used for straightening the straightness of the threaded steel on the vertical face; the second straightening mechanism is suitable for clamping the threaded steel in the horizontal direction and used for straightening the straightness of the threaded steel on the horizontal plane; the second straightening mechanism is further provided with a limiting structure which is used for limiting the threaded steel to rotate along the axis of the second straightening mechanism; and the third straightening mechanism is suitable for clamping the threaded steel in the vertical direction and used for straightening the straightness of the threaded steel on the vertical face. The threaded steel straightening device can prevent threaded steel from rotating in the moving process, so that the threaded steel can be straightened in the vertical direction and the horizontal direction; and the threaded steel straightening device has the beneficial effects of being good in straightening effect and stable in operation.

Description

technical field [0001] The invention relates to a straightening device, in particular to a straightening device and a straightening method for threaded steel. Background technique [0002] Rebar is widely used in civil engineering construction such as houses, bridges and roads. Rebar is an indispensable structural material for highways, railways, bridges, culverts, tunnels, flood control, dams and other public facilities, as small as the foundation, beams, columns, walls, and panels of house construction. With the continuous deepening of China's urbanization, the vigorous development of infrastructure construction and real estate has a strong demand for rebar. Rebar is a steel bar with ribs on the surface, also known as ribbed steel bar, usually with two longitudinal ribs and diagonal lines evenly distributed along the length. The shape of twill is spiral, herringbone and crescent. [0003] The traditional way of straightening round steel is to straighten in two direction...
