[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-5 As shown, a steel bar bending machine for civil engineering comprises an operating table 1 and a bending mechanism, the bending mechanism is arranged in the operating table 1, and the outer wall of the operating table 1 is also provided with a material discharge trough plate 9, a material transport plate 10 is slidably installed in the material discharge trough plate 9 and is lifted and lowered along the inner wall of the material discharge trough plate 9, and limiting grooves 13 are arranged on both sides of one of the opposite sides of the material transport plate 10, and a support frame 18 is fixedly installed at a position near each limiting groove 13 on the inner bottom surface of the material discharge trough plate 9, and a pulley 15 is rotatably connected to the upper and lower ends of the support frame 18, and a belt strip 16 is arranged on the outer sleeve of the pulley 15, and a driving block 14 plugged into the limiting groove 13 is fixedly connected to the belt strip 16, and a belt strip 16 is also sleeved between the pulleys 15 below the two support frames 18 on the opposite side of the material transport plate 10, and a motor 6 is fixedly installed on the inner bottom surface of the material discharge trough plate 9, and the main shaft of the motor 6 located at the material discharge trough plate 9 is fixed to one of the pulleys 15.

[0024] By adopting this technical solution, by setting a material discharge trough plate 9 and a material transport plate 10 driven by a motor 6, automatic loading of steel bars can be realized. Specifically, the motor 6 works to drive the pulley 15 to rotate, the rotation of the pulley 15 drives the belt strip 16 to rotate, the rotation of the belt strip 16 drives the driving block 14 to perform reciprocating lifting, the reciprocating lifting of the driving block 14 drives the material transport plate 10 to perform reciprocating lifting, and a plurality of steel bars are placed in the material discharge trough plate 9, and the steel bars will be on the material transport plate 10, and the two ends of the steel bars will be on the two supporting Between the supports 18, the material transport plate 10 will rise to a highest point when it is lifted or lowered. At this time, the steel bars can be transported to the top of the notch of the material discharge chute plate 9. Because the steel bars piled together are not blocked by the side walls of the material discharge chute plate 9, the steel bars at the top of the stacking end will roll downward under the action of gravity. Through the rolling of the steel bars, several steel bars will roll into the operating table 1, and the bending mechanism will perform the bending operation of the steel bars. In addition, the height of one side wall of the material discharge chute plate 9 away from the operating table 1 is higher than the height of the side wall of the operating table 1.

[0025] like Figure 1 and Figure 5 As shown, the bottom surface of the inner wall of the operating table 1 is provided with a plurality of slide grooves 12 distributed in a linear array and arranged parallel to the discharge chute plate 9, a support plate 2 for placing steel bars slides in the slide groove 12, a limit plate 4 located above the support plate 2 is slidably connected in the operating table 1, an arc groove 17 corresponding to the position of the support plate 2 is provided on the upper surface of the limit plate 4, a through groove 5 for the support plate 2 to pass through is provided in the arc groove 17, a rack 8 is fixed to the inner side wall of the operating table 1 near the corner, the rack 8 is engaged with a gear 7 which is rotatably connected to the limit plate 4 and slidably installed in the operating table 1, a motor 6 is fixedly installed on the limit plate 4, and the main shaft of the motor 6 located at the limit plate 4 is fixed to the gear 7.

[0026] By adopting this technical solution, by setting a limit plate 4 to limit the position of the steel bars rolled into the operating table 1, each support plate 2 can accurately hold up the steel bars, making it convenient for the bending mechanism to bend the steel bars. Specifically, after the steel bars roll into the operating table 1, they will fall onto the limit plate 4. Through the arc groove 17 opened on the limit plate 4, the steel bars can be rolled into the arc groove 17. At this time, the motor 6 located on the limit plate 4 works to drive the gear 7 to rotate. Due to the fixed position of the rack 8 and the limitation of the gear 7 by the operating table 1, the rotation of the gear 7 will drive the limit plate 4 to descend. By setting a through groove 5 just above the support plate 2, the limit plate 4 can be lowered to the bottom end of the support plate 2, thereby allowing the support plate 2 to hold up the steel bars located in the arc groove 17.

[0027] like Figure 3 and Figure 5As shown, the bending mechanism includes an electric cylinder 3 slidably mounted on the operating table 1, and electric push rods 11 are installed on the outer wall and the inner wall of the operating table 1. The electric push rod 11 on the outer wall is used to push the electric cylinder 3 to move, and the electric push rod 11 on the inner wall is used to push the support plate 2 to slide.

[0028] By adopting this technical solution, the steel bars can be bent by setting up an electric cylinder 3. Specifically, the telescopic end of the electric cylinder 3 squeezes the steel bars on the support plate 2, thereby completing the bending of the steel bars. By setting up an electric push rod 11 to push the electric cylinder 3 to move, the electric cylinder 3 can squeeze the steel bars on different support plates 2. In addition, by setting up an electric push rod 11 for pushing the support plate 2 to slide, before bending the steel bars, the electric push rod 11 works to push the support plate 2 to move, thereby adjusting the position of the steel bars, and realizing bending operations at different positions on the steel bar body.

[0029] like Figure 2 As shown, an electric push rod 11 is installed at the outer bottom of the operating platform 1. The electric push rod 11 located at the outer bottom is used to lift the operating platform 1. The electric push rod 11 located at the outer bottom of the operating platform 1 is arranged on the side away from the material discharge chute plate 9.

[0030] By adopting this technical solution, an electric push rod 11 is arranged at the bottom of the operating table 1 so that the telescopic end thereof extends when the operating table 1 is working, so that one side of the operating table 1 can be raised by a certain arc, so that the steel bars that have rolled onto the limiting plate 4 can be rolled back into the material discharge trough plate 9. Specifically, when a number of steel bars roll onto the limiting plate 4, some of the steel bars will roll into the arc groove 17, while the steel bars that have not rolled into the arc groove 17 will remain on the limiting plate 4. At this time, the electric push rod 11 works to lift one side of the operating table 1 to a certain height, so that the steel bars remaining on the limiting plate 4 can be rolled back into the material discharge trough plate 9. In addition, a magnet can be installed in the arc groove 17 so that when the operating table 1 is tilted, the steel bars in the arc groove 17 can be fixed in the arc groove 17 by magnetic attraction.

[0031] Working principle: put the steel bar in the discharge chute plate 9, start the motor 6 located at the discharge chute plate 9, drive the material transport plate 10 to rise and fall, and when the material transport plate 10 rises and falls to the top, the steel bar will roll out from the discharge chute plate 9 and roll onto the limit plate 4, of which part of the steel bar will roll into the arc groove 17, and the other part of the steel bar will remain on the limit plate 4. At this time, the electric push rod 11 located at the bottom of the operating table 1 is extended to lift one side of the operating table 1 to a certain height, so that the steel bar remaining on the limit plate 4 can be rolled back to discharge. In the slot plate 9, the steel bars in the arc groove 17 can be fixed in the arc groove 17 by magnetic attraction without rolling. After that, the motor 6 located on the limit plate 4 works to rotate the gear 7 to drive the limit plate 4 to descend, and the limit plate 4 is lowered to the bottom end of the support plate 2 through the through slot 5, so that the support plate 2 can lift the steel bars in the arc groove 17. After that, the electric cylinder 3 moves to the top of the steel bars through the extension of the electric push rod 11, and then the electric cylinder 3 works to squeeze the steel bars downward at its telescopic end to complete the bending operation of the steel bars.

[0032] The wiring diagram of the electric cylinder 3, the motor 6 and the electric push rod 11 in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the electric cylinder 3, the motor 6 and the electric push rod 11 are not explained in detail.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
