Labor-saving steel bar bending tool capable of controlling bending angle and method

Abstract

The invention belongs to the field of steel bar bending equipment and tools, and specifically relates to a labor-saving steel bar bending tool capable of controlling a bending angle and a method. Thelabor-saving steel bar bending tool capable of controlling the bending angle comprises a rotary bending mechanism, wherein the rotary bending mechanism comprises a rotating shaft, a rotating rod is arranged on one end of the rotating shaft, the rotating rod is perpendicular to the rotating shaft, two limiting rods are arranged on the other end of the rotating shaft, the two limiting rods are symmetrically arranged, the two limiting rods and the end surface of the rotating shaft form a C-shaped notch which is used for clamping a to-be-bent steel bar, two bearings are arranged on the rotating shaft, and the two bearings are fixedly installed on a base by virtue of bearing seats. The labor-saving steel bar bending tool has the advantages of the simple structure, convenience in field fabrication and low cost, and the problems of time consumption, labor consumption and potential safety hazards when temporary and scattered steel bars are manually bent due to no condition of a steel bar processing plant or due to the limitation to the distance to the steel bar processing plant on site are specifically solved.

Description

technical field [0001] The invention belongs to the field of steel bar bending equipment and tools, and in particular relates to a labor-saving and controllable bending angle steel bar bending tool and method. Background technique [0002] In engineering construction, steel bars often need to be bent on the construction site. A large number of steel bars are produced by making single-cut materials in the steel bar processing plant, but when scattered steel bars or construction sites with too long construction lines temporarily need to bend steel bars, due to the constraints of the site and the distance from the steel bar processing plant, manual bending is usually used. However, artificial steel bar bending is difficult and inefficient, and there is a certain deviation in the control of the bending angle of the steel bar, and there are certain safety risks.
