A manufacturing and processing system for hot-rolled rebar

Abstract

The invention relates to a threaded steel hot rolling manufacturing and processing system, comprising a main board, a conveying device, a heating furnace, a pressing device and a molding device, a conveying device is installed on the upper end of the main board, a heating furnace is installed on the right side of the conveying device, and On the main board, the right side of the heating furnace is provided with a profiling device, the profiling device is installed on the main board, and the right side of the profiling device is provided with a molding device. The present invention can solve the problem that the existing equipment cannot carry out secondary pressing treatment on the steel bar when pressing and forming the rebar, and the steel bar is prone to incomplete forming after pressing, which reduces the success rate of rebar forming. At the same time, it cannot The formed rebar is rectified, and the rebar is prone to excessive deformation during pressing, and it cannot be ensured that the rebar remains straight during pressing, and the rebar that is pressed and formed is prone to bending, thereby reducing the quality of rebar forming. effects and other issues.

Description

technical field [0001] The invention relates to the technical field of steel processing, in particular to a manufacturing and processing system for hot-rolled rebar. Background technique [0002] Rebar is a steel bar with ribs on the surface, also known as ribbed steel bar. It usually has 2 longitudinal ribs and transverse ribs evenly distributed along the length direction. The shapes of the transverse ribs are spiral, herringbone and crescent. The ribs on the surface are usually processed by hot rolling process. Rebar is a must-use steel for medium-sized and above building components. Due to the role of ribs, rebar has a greater bonding capacity with concrete, thus increasing the ability to withstand external forces. Therefore Rebar is widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. [0003] At present, the existing equipment usually has the following deficiencies when the rebar is pressed and formed...

Problems solved by technology

[0005] The invention can solve the problem that the existing equipment cannot carry out secondary pressing treatment on the steel bar when the rebar is pressed and formed, and the steel bar is prone to incomplete forming after pressing, thereby reducing the effect of rebar forming and reducing the rebar forming effect. At the same time, the rebar after forming cannot be rectified, and the rebar is prone to excessive deformation during pressing, and it cannot be ensured that the rebar is kept straight during pressing, and the rebar after pressing is prone to bending phenomenon, thereby reducing the effect of rebar forming and other problems
