Description

Reinforcing bar bending device for construction is built in room

Technical Field

The utility model relates to the technical field of reinforcing steel bar bending equipment, in particular to a reinforcing steel bar bending device for building construction.

Background

In house and building construction engineering, various specifications of steel bar frames are needed to be used, and the steel bar frames consist of steel bar frames formed by bending and unbent straight steel bars. The steel bar bending is completed by a steel bar bending machine, and the bending machine further comprises two fixing blocks with adjustable intervals for fixing the steel bar, so that the steel bar is fixed in the steel bar bending process. The steel bar bending machine is characterized in that a center column and a bending column are respectively arranged at the axis of the turntable and the eccentric position of the turntable through placing steel bars on the turntable during operation, and the turntable is driven to rotate through driving the turntable so as to drive the center column and the bending column to bend the steel bars.

The existing bending machine, for example, a steel bar bending machine with a publication number of CN218192257U, when bending steel bars with different diameters, utilizes a bidirectional shaft rotation driving device to drive two threaded rods to rotate, so that two threaded blocks are mutually close or far away from each other, two limiting blocks are mutually close or far away from each other, two fixing plates are mutually close or far away from each other, further, two groups of transmission rollers for clamping the steel bars are mutually close or far away from each other, and the clamping range of the two groups of transmission rollers is matched with the diameter of the steel bars. However, in the bending machine, when two groups of transmission rollers are adjusted, the positions of transverse lines perpendicular to connecting lines of the two groups of transmission rollers are unchanged, namely, when reinforcing steel bars with different diameters are clamped, the central lines of the reinforcing steel bars with different diameters are located on the same transverse line, namely, the transverse lines perpendicular to the connecting lines of the two groups of transmission rollers, the linear distance between the transverse lines and the positioning rod is inconvenient, however, in a specific operation process, the linear distance between the central lines of the reinforcing steel bars with different diameters and the positioning rod is changed, namely, the larger the linear distance between the central lines of the reinforcing steel bars with larger diameters and the positioning rod is larger, and in the bending machine, the linear distance between the central lines of the reinforcing steel bars and the positioning rod after the reinforcing steel bars are clamped and fixed cannot be changed according to the change of the diameters of the reinforcing steel bars, so that when the reinforcing steel bars with different diameters are bent, if the reinforcing steel bars with small diameters are just in contact fit with the positioning rod, the reinforcing steel bars with large diameters are not easy to contact and fit with the positioning rod, the bending operation is inconvenient, and the bending effect is easy to deviate from the expected effect. Therefore, we provide a reinforcing steel bar bending device for building construction.
