Rebar arc bending machine

Abstract

The invention discloses a rebar arc bending machine. The rebar arc bending machine comprises a machine body (1), a workbench face (2), a driving pressing roller (3), driven pressing roller (4) and rotating shafts (13), and is characterized in that the side, close to the driving pressing roller (3), on the machine body (1) provided with a folding plate (5) in a hinged manner; a base body is arranged on the workbench face (2), and is provided with a roller; a connection rod (14) is arranged between two rotating shafts (13), and is provided with a screw rod (15); the workbench face (2) is provided with a sliding groove (19) with an opening; and the rotating shafts (13) can move on the sliding groove (19). According to the rebar arc bending machine, the two driven pressing rollers can be adjusted at the same time through a handle, precision is high, adjusting is convenient, the workbench face can be increased due to a hinged supporting plate, the machining effect is good when a rebar is placed on the roller, it is not needed to hold the rebar by human hands, manpower is reduced, the supporting plate is laid down when the rebar arc bending machine is not used, and the floor space cannot be increased.

Description

technical field [0001] The invention relates to the technical field of steel bar processing, in particular to a steel bar arc bending machine. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the infrastructure of the country is becoming more and more perfect, and high-rise buildings are rising everywhere. Reinforced concrete is widely used in construction, and it is often necessary to bend steel bars into various shapes, especially in prefabricated concrete. During the construction of pipes, tunnels, etc. The steel bar bending machine is a machine that bends steel bars into a certain arc. It is one of the indispensable equipment for steel bar processing. It is mainly used for bending steel bars in engineering construction. The steel bar bending machine in the prior art mainly includes the frame , the frame is provided with an active pressure roller and a driven pressure roller, the active pressur...

The steel bar bending machine is a machine that bends steel bars into a certain arc. It is one of the indispensable equipment for steel bar processing. It is mainly used for bending steel bars in engineering construction. The steel bar bending machine in the prior art mainly includes the frame , the frame is provided with an active pressure roller and a driven pressure roller, the active pressure roller is connected to the power device, and the active pressure roller is reversed during work so as to drive the steel bar to move left and right, so that the steel bar can be gradually pressed into an arc shape or Circle, because a part of the steel bar in the form of a circle is vacant, in order to ensure the bending effect, workers need to hold the vacant part with their hands, and the end of the steel bar is easy to warp during the bending process, which has certain dangers. Some dynamic pressure rollers are adjustable and some are non-adjustable. Adjusting the distance of the driven pressure roller can change the bending arc of the steel bar, and the processing range is wide. In the prior art, the number of driven pressure rollers is generally two, and the two One separate adjustment, this adjustment method is not easy to control the adjustment distance of the two driven pressure rollers is exactly the same, it is easy to produce errors and affect the processing accuracy of the steel bar, and the two separate adjustments take a long time
