[0024] The above-mentioned steel bar straightening device for construction cooperates with each other through the feed port 2, the discharge port 3, the rotating shaft, the conveying roller, the rotating shaft and the clamping roller. When the steel bars need to be straightened, steel bars of different diameters can be inserted into the feed port of corresponding size, and pass through the conveying roller and the rotating shaft of the corresponding straightening diameter, and finally pass out from the discharge port, so that multiple steel bars of different diameters can be straightened at the same time, the applicability is good, and the work efficiency is greatly improved, and it can be used.

[0025] In one embodiment of the utility model, the upper end of the straightening box is provided with a box cover 4, and the upper end of the fixing frame 10 is connected to the lower end of the box cover 4. In order to disassemble and assemble the steel bar straightening device for construction, the convenience of maintenance is improved.

[0026] In one embodiment of the utility model, the edges of the straightening box 1 and the box cover 4 are fixed by U-shaped clips 17 and bolts 18, and the upper end of the straightening box 1 is fixedly connected with a flange 16 to increase the contact area with the box cover 4, so that the connection between the box cover 4 and the straightening box 1 can be more stable; a plurality of U-shaped clips 17 are arranged at circumferential intervals between the flange 16 and the box cover 4, so that the box cover 4 is not easy to separate from the straightening box 1; bolts 18 are passed through each U-shaped clip 17 in the vertical direction; the box cover 4 is detachably connected to the straightening box 1 through the cooperation of the flange 16, the U-shaped clip 17 and the bolts 18. When it is necessary to inspect or replace the object in the straightening box 1, first remove the bolts 18, and then remove the U-shaped clip 17 to separate the box cover 4 from the straightening box 1.

[0027] In one embodiment of the utility model, a second arc-shaped straightening groove 13 is provided at a position corresponding to the first arc-shaped straightening groove 9 of the corresponding conveying roller 7, and the shapes, sizes and straightening boxes of the first arc-shaped straightening groove 9 and the second arc-shaped straightening groove 13 are arranged in opposite directions, so that a space capable of accommodating steel bars is formed between the first arc-shaped straightening groove 9 and the second arc-shaped straightening groove 13.

[0028] In one embodiment of the utility model, the rotary drive mechanism 6 includes a drive motor 601 fixedly connected to the straightening box 1, a plurality of double-hook pulleys 602 respectively provided at the ends of the plurality of conveying rollers 7, and a plurality of belts 603 connecting two adjacent double-hook pulleys 602, and the drive motor is connected to one of the rotating shafts 5. When the drive motor 601 is working, it drives one of the rotating shafts 5 to rotate, so that through the cooperation of the double-hook pulley 602 and the belt 603, each rotating shaft 5 can be driven to rotate synchronously, and then the steel bars are conveyed, so that the steel bars can pass between the first arc straightening groove 9 and the second arc straightening groove 13 for straightening.

[0029] In one embodiment of the utility model, each of the conveying rollers 7 includes two arc blocks 701 and arc clamping plates 702 arranged on both sides of the arc blocks 701, and the upper and lower ends of the arc clamping plates 702 are provided with fastening bolts 703. The fastening bolts 703 pass through the arc clamping plates 702 and are abutted against the rotating shaft 5. The middle part of the arc block 701 is provided with a first arc straightening groove 9. Specifically, an arc clamping plate 702 is fixedly connected to the side where the two arc blocks 701 are close to each other. The two arc clamping plates 702 cooperate with each other to form a cylindrical structure clamped on the rotating shaft 5. A number of fastening bolts 703 are connected between the cylindrical structure and the rotating shaft 5. Since the steel bar needs to pass through the first arc straightening groove 9, after long-term use, the conveying roller 7 is easily worn out and cannot be used normally. At this time, the box cover 4 is opened, and then the fastening bolts 703 are removed to separate the two arc blocks 701 and remove them from the rotating shaft 5, so that the conveying roller 7 can be replaced. The structure is simple and easy to operate. The structure of the pressure roller 12 is the same as that of the conveying roller 7, which is easy to operate.

[0030] In one embodiment of the utility model, a frame 14 is fixedly connected to the periphery of the feed ports 2 of the same size. An identification plate 15 corresponding to each of the frames 14 is fixedly connected to the straightening box 1. It should be noted that the conveying roller 7 has multiple straightening diameters, and correspondingly, the feed ports 2 also have multiple sizes, wherein a frame 14 is fixedly connected to the periphery of the feed ports 2 of the same size, and an identification plate 15 corresponding to each of the frames 14 is fixedly connected to the straightening box 1, and the size of the feed port 2 at that location can be marked on the identification plate 15, so that steel bars of different diameters can be quickly inserted into the corresponding feed port 2.

[0031] When the above-mentioned steel bar straightening device for construction is used, steel bars of different diameters are inserted into the corresponding size of the feed port 2, and the ends of the steel bars are inserted between the first arc-shaped straightening groove 9 and the second arc-shaped straightening groove 13 of the corresponding size, and then the drive motor 601 is started to drive the rotating shafts 5 to rotate synchronously, thereby driving the conveying roller 7 to rotate, so as to convey the steel bars, so that the steel bars pass through the subsequent first arc-shaped straightening groove 9 and the second arc-shaped straightening groove 13 in sequence, and then the steel bars are straightened, and the straightened steel bars pass out from the discharge port 3; in this process, a plurality of steel bars of different diameters can be straightened at the same time, which greatly improves the applicability and working efficiency of the device.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
