Description

Technical Field

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

[0002] When constructing the base plate, floor slab, and larger beams and columns of a building structure, the ends of the prefabricated steel components need to be bent into a certain angle. If the steel bars are bent before being put into the mold, the end mold cannot be installed. Therefore, in actual construction, the ends of the steel bars that need to be bent are often pre-processed into straight sections, and then the ends of the steel bars are bent.

[0003] According to Chinese patent: CN214683996U, a steel bar bending machine for construction engineering includes a fixed frame, a fixed plate is fixedly connected to the top of the fixed frame, a support frame is fixedly connected to the surface of the fixed plate, a fixed guide roller is arranged at the end of the support frame, an adjusting device is arranged inside the fixed frame, a mounting frame is fixedly connected to the end of the adjusting device, a moving guide roller is fixedly connected to the surface of the mounting frame, a connecting frame is fixedly connected to the side wall of the fixed frame, a rotating device is fixedly connected to the end of the connecting frame, a limiting device is fixedly connected to the end of the rotating device, and the limiting device is connected to the adjusting device; a handle is fixedly connected to the surface of the connecting frame; the adjusting device includes a rotating screw, the rotating screw is rotatably connected to the fixed frame, the rotating screw is rotatably connected to the fixed plate, the end of the rotating screw is fixedly connected to a rotating disk, the rotating screw is threadedly connected to a screw slider, a guide rod is fixedly connected to the inner wall of the fixed frame, the screw slider is slidably connected to the guide rod, a push rod is fixedly connected to the surface of the screw slider, and the push rod is slidably connected to the fixed plate. Based on the above patents and in combination with the prior art, it is found that:

[0004] 1. When bending steel bars, the steel bars will be subjected to a large torque, which will cause the steel bars to shake. However, although some current steel bar bending machines have a fixed structure, they do not have the function of adjusting and clamping, and cannot adapt to steel bars of different thicknesses. Especially when bending thinner steel bars, workers are required to manually press the steel bars to ensure their stability, which not only reduces work efficiency, but also increases the labor intensity of workers.

[0005] 2. Before bending the steel bars, people usually need to mark the bending position on each steel bar in turn, and then use tools to clamp the steel bars for bending. However, for a large number of steel bars, it may take a lot of time and manpower. Utility Model Content

DETAILED DESCRIPTION

[0037] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0038] Example: Figure 1-2 As shown, a multi-head steel bar bending machine includes: an electric push rod 15, which adopts a linear electric push rod of the LA12 series, which has a compact design and a small size, is suitable for installation in a limited space, and can meet some applications with strict size requirements; a rotating shaft 2, one end of which is fixedly connected to the output end of the motor. First, after the steel bar body 17 is placed on the upper end of multiple U-shaped placement plates 6, the electric push rod 15 is started, so that the moving plate 10 drives the pressing plate 13 to move until the insert block 12 is inserted into the slot 8. At this time, the pressing plate 13 is just above the steel bar body 17, and then the hydraulic rod 14 is started to move the pressing plate 13 downward until the pressing plate 13 presses and fixes the steel bar body 17. By adjusting the height of the pressing plate 13, steel bars of different thicknesses can be pressed and fixed, thereby improving work efficiency. After the steel bar body 17 is fixed, the motor is started to make the rotating shaft 2 drive the extrusion rod 4 to rotate 90 degrees clockwise. Under the rotation and extrusion of the extrusion rod 4, the left end of the steel bar body 17 is bent 90 degrees. At the same time, the rightmost motor is started to make the rotating shaft 2 drive the extrusion rod 4 to rotate 90 degrees counterclockwise, so that the right end of the steel bar body 17 is bent 90 degrees. Finally, the fixation of the leftmost steel bar body 17 is released, and the extrusion rod 4 is rotated 90 degrees clockwise, so that the steel bar body 17 at the middle end drives the leftmost steel bar body 17 to rotate 90 degrees. Through multiple bending heads, the steel bar body 17 is bent into a rectangular shape. Finally, through multiple bending heads, different positions of the steel bar body 17 can be bent.

[0039] like Figure 3-4 As shown, the slider 7 is slidably connected with the mounting plate 5. The slider 7 and the lower end surface of the mounting plate 5 are provided with a plurality of threaded holes. After adjusting the position of the bending head, the slider 7 and the mounting plate 5 are fixed by inserting bolts into the threaded holes. By setting the slider and the scale line, multiple bending heads are fixed to multiple sliders respectively. The operator can adjust the bending head to a suitable position by moving the slider 7 according to the required size of the steel bar body 17. The scale line 11 can provide an accurate reference to help the operator control the accuracy of the bending position. There is no need for the cumbersome process of marking on the steel bar body 17, which improves the operating efficiency and accuracy.

[0040] Working principle: First, after placing the steel bar body 17 on the upper ends of multiple U-shaped placement plates 6, start the electric push rod 15 to make the movable plate 10 drive the pressure plate 13 to move until the plug block 12 is inserted into the slot 8. At this time, the pressure plate 13 is just above the steel bar body 17, and then start the hydraulic rod 14 to move the pressure plate 13 downward until the pressure plate 13 presses and fixes the steel bar body 17. By adjusting the height of the pressure plate 13, steel bars of different thicknesses can be pressed and fixed, thereby improving work efficiency. After the steel bar body 17 is fixed, the motor is started to make the rotating shaft 2 drive the extrusion rod 4 to rotate 90 degrees clockwise. Under the rotation and extrusion of the extrusion rod 4, the left end of the steel bar body 17 is bent 90 degrees. At the same time, the rightmost motor is started to make the rotating shaft 2 drive the extrusion rod 4 to rotate 90 degrees counterclockwise, so that the right end of the steel bar body 17 is bent 90 degrees. Finally, the fixation of the leftmost steel bar body 17 is released, and the extrusion rod 4 is rotated 90 degrees clockwise, so that the steel bar body 17 at the middle end drives the leftmost steel bar body 17 to rotate 90 degrees. Through multiple bending heads, the steel bar body 17 is bent into a rectangular shape. Finally, through multiple bending heads, different positions of the steel bar body 17 can be bent. By setting sliders and scale lines and fixing multiple bending heads to multiple sliders respectively, the operator can adjust the bending head to a suitable position by moving the slider 7 according to the required size of the steel bar body 17. The scale line 11 can provide an accurate reference to help the operator control the accuracy of the bending position. There is no need for the tedious process of marking on the steel bar body 17, thereby improving the operating efficiency and accuracy.
