Description

Technical Field

[0001] The present application relates to the technical field of steel bar bending, and in particular to an auxiliary device for bending in construction engineering. Background Art

[0002] The most important building material in construction projects is steel bars. When steel bars are used, they sometimes need to be bent to greatly improve the utilization efficiency of steel bars. At first, manual bending was used, and positioning screws were welded on the workbench, and then they were bent manually. The labor intensity was high and the bending quality was not ideal. Later, steel bar bending machines appeared on the market to reduce people's labor intensity.

[0003] The rebar bending machine recorded in the related art includes a base, a U-shaped bracket 1 is fixed on the top of the base, a lower clamp seat is symmetrically slidably provided on the top of the base, the lower clamp seats are symmetrically distributed on both sides of the U-shaped bracket 1, upper clamp seats are provided above the lower clamp seats, the bottom ends of the upper clamp seats are symmetrically rotatably embedded with screws, the top ends of the lower clamp seats are provided with threaded grooves matching the screws, a fixed plate is slidably provided between the vertical parts of the U-shaped bracket 1, a U-shaped bracket 2 is fixedly provided at the bottom end of the fixed plate, and a plurality of bending plates are fixedly provided in an array at the bottom end of the horizontal part of the U-shaped bracket 2. This rebar bending machine can be applied to the bending of rebars of different specifications, and can effectively prevent the rebars from sliding during the bending process, thereby effectively improving the efficiency and quality of rebar bending.

[0004] When the device is used, the two ends of the steel bar are clamped and fastened by the clamping device. When the steel bar is bent, the clamping device will follow the descent of the steel bar and move downward. However, due to the existence of the clamping device, the two ends of the steel bar are still straight after being bent. At the same time, the side walls at both ends of the through groove will cause the steel bar to be divided into three sections that are not in the same straight line after being completely bent, resulting in different bending degrees of the steel bar.

Vertically arranged limiting holes 4 are provided on the two side walls in the width direction of the box body 1, and a limiting groove 5 is provided at one end of each adjusting plate 2 away from the bottom of the box body 1. The two limiting holes 4 and the two limiting grooves 5 are relatively arranged. The pressing assembly 3 is arranged on the box body 1 for bending steel bars.

[0037] When in use, the angle between the two adjusting plates 2 is adjusted according to actual processing requirements, and the steel bar is placed in the limiting hole 4. When the height of the top of the adjusting plate 2 is lower than the lower end of the limiting hole 4, the steel bar is initially located in the limiting hole 4. As the pressing component 3 bends the steel bar, the steel bar will fall into the limiting groove 5; when the height of the top of the adjusting plate 2 is higher than the lower end of the limiting hole 4, the steel bar is initially located in the limiting groove 5. During the bending process, the steel bar will always be located in the limiting groove 5. The steel bar will be in the limiting groove 5 and will only be restricted but not subjected to force. Therefore, when the steel bar is bent, the two ends of the steel bar will not form different degrees of bending, thereby improving the bending quality of the steel bar.

The first linear drive member 31 is installed on the top of the box body 1 and the output shaft of the first linear drive member 31 is passed through the box body 1. The pressing plate 32 is connected to the output shaft of the first linear drive member 31 and is perpendicular to the output shaft of the first linear drive member 31. The pressing plate 32 is arranged along the width direction of the box body 1, and the two adjustment plates 2 are symmetrically arranged about the center line of the width direction of the pressing plate 32. After placing the steel bar in the limiting hole 4, start the first linear drive member 31 to drive the pressing plate 32 to descend, thereby bending the steel bar. The first linear drive member 31 can be a hydraulic cylinder, a pneumatic cylinder, etc. In this embodiment, the first linear drive member 31 is not limited.
