[0002] Building steel bars refer to steel materials used in reinforced concrete and prestressed reinforced concrete. Their cross-sections are circular, and sometimes square with rounded corners, including plain round steel bars, ribbed steel bars, and twisted steel bars. In engineering construction, steel bars are widely used in various building structures, especially large-scale, heavy-duty, light-thin-walled, and high-rise building structures. Therefore, during the building construction process, it is often necessary to process building steel bars on-site, cutting the longer steel bars into appropriate lengths for use.

[0025] Please refer to Figures 1-5, the present utility model provides a technical solution: a building steel bar cutting device, which includes a base 1. Vertical plates 2 are fixedly connected to both sides of the base 1. First chutes 3 are opened on the sides of the vertical plates 2 away from the base 1. Wheel grooves 4 are opened at the tops of the vertical plates 2. First electric sliders 5 are slidably connected in the first chutes 3. Connecting plates 6 are fixedly connected to the first electric sliders 5. The connecting plates 6 are L-shaped plate structures. A moving component 7 is fixedly connected between the two connecting plates 6. The moving component 7 includes two moving plates 71. The two moving plates 71 are respectively fixedly connected to the two connecting plates 6. Grooves 72 are opened at the bottoms of the two moving plates 71. The grooves 72 have the same width as the wheel grooves 4 and are corresponding. Two groups of rollers 73 are symmetrically and fixedly installed in the grooves 72. The rollers 73 are in rolling connection with the wheel grooves 4. A connecting member 74 is fixedly connected between the upper ends of the two moving plates 71. Therefore, when the two first electric sliders 5 move, they will drive the two moving plates 71 and the connecting member 74 therebetween to move synchronously under the cooperation of the rollers 73 and the wheel grooves 4. A third chute 75 is opened on the connecting member 74. A second electric slider 76 is slidably connected in the third chute 75. An installation frame 77 is fixedly connected to the bottom end of the second electric slider 76. A driving motor 78 is fixedly installed in the installation frame 77. The output end of the driving motor 78 is fixedly connected to a cutting blade 79.

[0026] A scale plate 8 is fixedly connected to one side of the base 1. Two second chutes 9 are symmetrically opened at the top of the base 1. First lead screws 10 are arranged in the two second chutes 9. The two first lead screws 10 are rotatably connected to the base 1 and the vertical plates 2. First turntables 11 are fixedly connected to one ends of the two first lead screws 10. First sliding blocks 12 are slidably connected in the two second chutes 9. The two first lead screws 10 are respectively threadedly connected to the two first sliding blocks 12. Fixed boxes 13 are fixedly connected to the tops of the two first sliding blocks 12. The fixed boxes 13 are hollow box-shaped structures. Indicator needles 16 are fixedly connected to the sides of the fixed boxes 13 close to the scale plate 8. A plurality of through slots 14 are evenly opened at the tops of the two fixed boxes 13. Clamping components 15 are arranged on the fixed boxes 13. The clamping components 15 include second lead screws 151 and a plurality of first clamping blocks 152. A second turntable 153 is fixedly connected to one end of the second lead screw 151. The other end of the second lead screw 151 passes through the side wall of the fixed box 13 and extends into the interior of the fixed box 13, and is rotatably connected to one side inside the fixed box 13. A plurality of second sliding blocks 154 are threadedly connected to the second lead screw 151. The plurality of second sliding blocks 154 can slide in the fixed box 13. Second clamping blocks 155 are fixedly connected to the tops of the plurality of second sliding blocks 154. The plurality of second clamping blocks 155 are respectively slidably connected to the plurality of through slots 14. Rubber pads 156 are fixedly connected to the sides of the first clamping blocks 152 and the second sliding blocks 154 close to each other.

[0027] It should be noted that this device is only suitable for cutting short steel bars. If it is necessary to cut long steel bars, on the basis of the above technical solution, through slots may be opened in both vertical plates 2. The through slots on the two vertical plates 2 need to correspond horizontally, and the central axis is on the same horizontal plane as the first clamping block 154 and the second clamping block 155.

[0028] It should be noted that the present utility model is a building steel bar cutting device. When steel bar cutting work is required, the staff places the steel bars to be cut on the side where the rubber pads 156 on each first clamping block 152 are located according to requirements, and then rotates the second turntable 153 to drive the second lead screw 151 to rotate. Due to the threaded connection between the second lead screw 151 and the second sliding block 154, the second sliding block 154 moves in the fixed box 13, thereby driving the second clamping block 155 on the second sliding block 154 to move in the through slot 14 towards the first clamping block 152 until the steel bars to be cut are clamped and fixed. The setting of several first clamping blocks 152 and several second clamping blocks 155 on the clamping assembly 15 can clamp multiple steel bars simultaneously to meet the requirement of cutting multiple steel bars at the same time. When clamping and fixing the steel bars, by rotating the two first turntables 11, the two first lead screws 10 can be rotated synchronously. Due to the threaded connection between the first lead screw 10 and the first sliding block 12, the first sliding block 12 can move in the second chute 9, thereby changing the distance between the two first sliding blocks 12, and thus changing the distance between the fixed boxes 13 at the tops of the two first sliding blocks 12. In cooperation with the scale plate 8 and the indicating needle on the fixed box 13, the steel bars can be measured, so as to facilitate cutting the steel bars into the required sizes. After the steel bars are fixed, by controlling the second electric slider 76 to move in the third chute 75, the mounting bracket 77, the drive motor 78 and the cutting blade 79 connected to its bottom end can be driven to move synchronously until the cutting blade 79 moves to the position on the steel bar corresponding to the scale plate 8 where cutting is required. Then, the drive motor 78 is started to drive the cutting blade 79 to rotate, and then the first electric slider 5 is controlled to move in the first chute 3 to drive the moving assembly 7 to move towards the steel bar until the rotating cutting blade 79 cuts the fixed steel bars one by one in sequence. Compared with the existing building steel bar cutting devices, the present utility model can cut multiple steel bars simultaneously through design and can measure the steel bars, so as to facilitate cutting the steel bars into the required sizes, improving the cutting efficiency of the steel bars and saving time and effort.
