Straightening device for production of high-line hot-rolled plain round steel bars and using method thereof

Abstract

The invention discloses a straightening device for production of high-line hot-rolled plain round steel bars and using method thereof. The straightening device comprises a supporting plate, the top of the supporting plate is symmetrically and fixedly connected with fixing plates, the interiors of the fixing plates are fixedly connected with second motors, and the output ends of the second motors are fixedly connected with lower traction rollers. The straightening device has the beneficial effects that by arranging upper traction rollers, the lower traction rollers, third electric telescopic rods and driving boxes, the traction function on steel bars of different sizes is achieved; by arranging a lifting seat, a connecting box, a lifting block, a first arc-shaped groove, a clamping block, a fixing block and a second arc-shaped groove are arranged, so that the function of clamping the steel bars is achieved; and by arranging a lifting plate, a pressing plate, a cutting disc, a limiting sliding rod and a spring, so that the function of cutting off straightened steel bars is achieved, use is convenient, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of straightening devices, in particular to a straightening device for high-wire hot-rolled smooth round steel bar production and a method for using the straightening device. Background technique [0002] Hot-rolled steel bars are finished steel bars that have been hot-rolled and naturally cooled. They are made of low-carbon steel and ordinary alloy steel at high temperatures. They are mainly used for reinforcement of reinforced concrete and prestressed concrete structures. They are used in civil engineering One of the most used steel varieties, hot-rolled steel bars should have a certain strength, that is, yield point and tensile strength, which are the main basis for structural design. At the same time, in order to meet the requirements of structural deformation, seismic energy absorption and processing, Hot-rolled steel bars should also have good plasticity, toughness, weldability, and bonding performance ...

[0002] Hot-rolled steel bars are finished steel bars that have been hot-rolled and naturally cooled. They are made of low-carbon steel and ordinary alloy steel at high temperatures. They are mainly used for reinforcement of reinforced concrete and prestressed concrete structures. They are used in civil engineering One of the most used steel varieties, hot-rolled steel bars should have a certain strength, that is, yield point and tensile strength, which are the main basis for structural design. At the same time, in order to meet the requirements of structural deformation, seismic energy absorption and processing, Hot-rolled steel bars should also have good plasticity, toughness, weldability, and bonding performance between steel bars and concrete; The labor intensity of the staff is high, and there is no clamping mechanism for the steel bar, which is not convenient to use
