Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a steel bar bending machine. Background Art

[0002] A large number of steel bars are needed on construction sites, and some of them need to be bent. Since manual bending is inefficient, a steel bar bending machine is used for the bending operation.

[0003] According to the publication number: CN214053487U, a steel bar bending machine is disclosed, which includes an operating table and a rotating disk, the rotating disk is rotatably connected to the upper surface of the operating table, and the operating table can rotate in a horizontal plane; a fixed plate fixedly connected to the operating table is provided on one side of the rotating disk, and a limit pin is detachably connected to the fixed plate, a center pin coaxial with the rotating disk is provided on the rotating disk, and a bending pin is also provided on the rotating disk, and a limit device is also provided on the fixed seat, and the limit device is fixedly provided at one end of the fixed plate away from the positioning pin, and the end of the limit device close to the limit pin and the limit pin can respectively contact the two side walls of the steel bar to be bent. The application has the effect of reducing the probability of workers being injured.

[0004] It can be seen that the bending machine in the prior art covers the bending part with a protective cover to reduce the harm to workers caused by the breakage of steel bars during bending. However, since the steel bar machine requires workers to take the materials when loading and unloading in most cases, the workers will stay near the bending machine when the steel bars are bent. If the steel bars break, the bending force is large and the steel bars are easily splashed outward, which will still have a certain impact on the workers. Utility Model Content

[0005] The utility model aims to provide a steel bar bending machine to solve the technical problem that the steel bar machine proposed in the background technology requires workers to take the materials when loading and unloading in most cases, so that the workers will stay near the bending machine when the steel bars are bent. If the steel bars are broken, the bending force is large, which may easily cause the steel bars to splash outward, which will still have a certain impact on the workers.

[0006] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a steel bar bending machine, including a workbench, a bending mechanism is installed on the workbench, a loading platform is arranged on one side of the workbench, a movable groove is provided at the bottom of the loading platform, a movable plate is slidably connected in the movable groove, a screw rod is rotatably arranged in the movable groove, the screw rod is threadedly connected to the lower side of the movable plate, storage plates are arranged on the upper sides of the movable plate and the loading platform, a storage groove is provided on the storage plate, a loading mechanism is installed between the movable plate and the loading platform, and the loading mechanism receives and transports the workpiece in the storage groove.

[0034] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a steel bar bending machine of the utility model in conjunction with the accompanying drawings.

[0035] like Figure 1-Figure 8As shown, a steel bar bending machine of the utility model comprises a workbench 1, on which a bending mechanism 2 is installed, the bending mechanism 2 comprises a first cylinder 21 installed on the workbench 1, the piston end of the first cylinder 21 is connected to one side of a first arc plate 22, a symmetrical column 24 is arranged on the lower side of the first arc plate 22, a second arc plate 23 is arranged on the lower side of the column 24, a bending plate 25 is arranged on the workbench 1 away from one end of the first cylinder 21, and a bending groove 26 is provided on the bending plate 25, when the steel bar enters between the bending plate 25 and the first arc plate 22, the first cylinder 21 pushes the first arc plate 22 and the second arc plate 23 to push the steel bar, and the columns 24 on both sides push the steel bar into the bending groove 26 to form a bend.

[0036] In order to enable workers to load materials at a distance from the workbench 1, a loading platform 3 is set on one side of the workbench 1, and a moving groove 311 is opened at the bottom of the loading platform 3. The moving plate 31 is slidably connected in the moving groove 311. A screw rod 312 is rotatably set in the moving groove 311. The screw rod 312 is threadedly connected to the lower side of the moving plate 31. The screw rod 312 is driven by a motor.
