Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present utility model.

[0028] Next, various non-restrictive embodiments of the present utility model will be specifically introduced. The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0029] Such as Figure 1 、 Figure 2As shown, an automatic steel-dividing device for producing ribbed steel bars comprises a bracket 2 and a chain conveying mechanism 1, wherein the chain conveying mechanism 1 comprises a plurality of chains 3 and a driving motor 11 mounted on the bracket 2, wherein each chain 3 is assembled on the bracket 2 in rotation around an axis extending in the left-right direction, and the plurality of chains 3 are arranged at intervals, parallel to each other, and in parallel along the left-right direction. The number of chains 3 in this embodiment is six, and the specific number of chains 3 can also be determined according to the actual length of the steel bars. A rotating shaft 9 assembled coaxially in rotation around an axis extending in the left-right direction is provided on the bracket 2. A plurality of bearing seats 18 are fixedly mounted on the bracket 2, and the rotating shaft 9 is assembled in rotation on the bearing seats 18, and the bearing seats 18 can better rotate the rotating shaft 9. The driving motor 11 is connected to the rotating shaft 9 in transmission, so that the rotating shaft 9 can rotate, and the rotating shaft 9 is connected to all the chains 3 in transmission. When the steel bars are transported, the axis of the steel bars and the chains 3 are perpendicular, and the arrangement of a plurality of chains 3 is more convenient for transporting the steel bars. The steel bars in this embodiment are ribbed steel bars.

[0030] A steel-dividing mechanism 10 is provided at the rear end of the chain conveying mechanism 1, and the steel-dividing mechanism 10 includes a plurality of side steel-dividing parts and a middle steel-dividing part 4 movably assembled on the bracket 2, and a steel-dividing driving part that drives the side steel-dividing parts and the middle steel-dividing part 4 to move in the up and down directions respectively. In this embodiment, the steel-dividing driving part corresponds one-to-one with the side steel-dividing parts and the middle steel-dividing part 4. The steel-dividing driving part in this embodiment is a hydraulic cylinder 13. In other embodiments, the steel-dividing driving part can be a cylinder or an electric push rod. The structures of the plurality of side steel-dividing parts and the middle steel-dividing part 4 are the same, and the working process is the same. The number of the side steel-dividing parts in this embodiment can be determined according to the actual length of the steel bar. The longer the length of the steel bar, the more the number of the side steel-dividing parts. There are four side steel-dividing parts in this embodiment, namely, a first side steel-dividing part 5, a second side steel-dividing part 6, a third side steel-dividing part 7, and a fourth side steel-dividing part 8. The first side dividing steel piece 5 , the second side dividing steel piece 6 , the third side dividing steel piece 7 and the fourth side dividing steel piece 8 are evenly distributed at the rear end of the chain conveying mechanism 1 along the left-right direction, and a middle dividing steel piece 4 is arranged at the middle position of the rear end of the chain conveying mechanism 1 .

[0031] During the operation of the steel bar separating mechanism 10, first, the middle steel bar separator 4 rises and jacks up, separating multiple steel bars first. At this time, there will be a gap between the separated steel bars. Immediately afterwards, the first side steel bar separator 5 and the second side steel bar separator 6 on both sides of the middle steel bar separator 4 will simultaneously rise and jack up towards the separated gap. At this time, there will also be a separated gap between the steel bars. Then, the third side steel bar separator 7 and the fourth side steel bar separator 8 will simultaneously rise and jack up towards the separated gap, thus separating multiple steel bars into two parts. In this embodiment, the side steel bar separators do not rise simultaneously to ensure that all side steel bar separators can rise along the same gap separated by the middle steel bar separator 4, preventing disorder in steel bar separation. When the steel bar separating mechanism 10 needs to descend and reset, the first side steel bar separator 5, the second side steel bar separator 6, the third side steel bar separator 7, the fourth side steel bar separator 8 and a middle steel bar separator 4 descend and reset simultaneously. According to the above process, the problems of disordered arrangement and incomplete separation of multiple steel bars can be solved.

[0032] Since the structures of multiple side steel bar separators and a middle steel bar separator 4 are the same, only the structure of the middle steel bar separator 4 will be described in detail in this embodiment. As Figure 2 shown, a mounting seat 12 is installed on the bracket 2, a hydraulic cylinder 13 is assembled on the mounting seat 12, the telescopic shaft 14 of the hydraulic cylinder 13 telescopically moves in the up and down direction, a connecting member 17 is provided at the top of the telescopic shaft 14, and the connecting member 17 is hinged to the middle steel bar separator 4. The upper end of the middle steel bar separator 4 is of a pointed structure, and the pointed structure can more accurately separate more steel bars. There are two wedge-shaped surfaces on the middle steel bar separator 4, and the two wedge-shaped surfaces face the front side and the rear side respectively. The two wedge-shaped surfaces on the middle steel bar separator 4 can guide the steel bars, enabling better separation of multiple steel bars. At the same time, a guide rod 15 extending in the up and down direction is assembled on the middle steel bar separator 4, a linear bearing 16 is provided on the mounting seat 12, and the guide rod 15 passes through the linear bearing 16, so that the guide rod 15 is guidingly and slidably assembled on the mounting seat 12. The arrangement of the guide rod 15 and the linear bearing 16 can make the movement of the middle steel bar separator 4 more stable.

[0033] The working process of the present utility model is as follows:

[0034] During the operation of the steel bar separating mechanism 10, first, the middle steel bar separating member 4 rises and jacks up, separating multiple steel bars first. At this time, there will be a gap between the separated steel bars. Immediately afterwards, the first side steel bar separating member 5 and the second side steel bar separating member 6 on both sides of the middle steel bar separating member 4 will simultaneously rise and jack up towards the separated gap. At this time, there will also be a separated gap between the steel bars. Then, the third side steel bar separating member 7 and the fourth side steel bar separating member 8 will simultaneously rise and jack up towards the separated gap, thus separating the multiple steel bars into two parts; when the steel bar separating mechanism 10 needs to descend and reset, the first side steel bar separating member 5, the second side steel bar separating member 6, the third side steel bar separating member 7, the fourth side steel bar separating member 8 and a middle steel bar separating member 4 will simultaneously descend and reset. According to the above process, the problems of disordered arrangement and incomplete separation of multiple steel bars can be solved.
