[0026] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a bending machine with a high degree of automation through improvement. The technical solution of the utility model is:

[0028] like Figure 1-Figure 4 As shown, a bending machine with a high degree of automation includes a frame 1, two through slots 2 are symmetrically provided on the inner side of the frame 1, and the two through slots 2 are used to facilitate the insertion of steel bars. An extrusion slot 12 is fixed on the inner side of the frame 1, and also includes: a bending mechanism, which is arranged on the inner side of the frame 1; the bending mechanism includes two connecting shafts 3 symmetrically fixed on the inner side of the frame 1, and an electric telescopic rod 4 installed on the inner side of the frame 1. The outer sides of the two connecting shafts 3 are both rotatably connected with gears 5, and the two gears 5 are meshed. Through the meshing of the two gears 5, when one of the gears 5 rotates, it will drive the other gear 5 to rotate in the opposite direction. One end of the two connecting shafts 3 is fixed with a snap-fitting Wheel 6, engage the steel bar with the groove on the outside of the two engaging wheels 6, so that the steel bar can be placed and prevented from rolling down. The outsides of the two connecting shafts 3 are rotatably provided with rotating blocks 7, and one side of the two rotating blocks 7 is fixed with bending wheels 8. The two ends of the steel bar are bent by the two bending wheels 8. A connecting arm 9 is fixed on the outside of the telescopic end of the electric telescopic rod 4, and a rack 10 meshing with one of the gears 5 is fixed at one end of the connecting arm 9. The telescopic end of the electric telescopic rod 4 is provided with a bending block 11, and the middle section of the steel bar can be bent by the bending block 11. Through the above description, the bending of the middle section or both ends of the steel bar is realized, which improves the practicability of the device.

[0029] like Figure 3 As shown, in one embodiment, in order to ensure the bending effect of the middle section of the steel bar, a plug-in rod 13 is fixed on one side of the two rotating blocks 7, and the two plug-in rods 13 are respectively inserted and slidably inserted into the two gears 5 and the inner side of the frame 1, and the outer sides of the two plug-in rods 13 are sleeved with springs 14, one end of the two springs 14 is respectively fixed to one side of the two gears 5, and the other ends of the two springs 14 are respectively fixed to one side of the two rotating blocks 7. When the middle section needs to be bent, the two rotating blocks 7 are respectively moved to make the two rotating blocks 7 slide along the outer sides of the two connecting shafts 3 respectively. At the same time, the two rotating blocks 7 will squeeze the two springs 14 at the same time, and the elastic potential energy of the two springs 14 is used to ensure the subsequent resetting of the two rotating blocks 7. When the two rotating blocks 7 are respectively in contact with the two gears 5, they can be fixed. When the middle section of the steel bar is bent, the two bending wheels 8 will not contact the steel bar.

[0030] like Figure 3 As shown, in one embodiment, the inner sides of the two gears 5 and the rotating block 7 are provided with limiting screw holes 15, and the two rotating blocks 7 and the gears 5 can be limited by rotating and inserting the bolts into the inner sides of the two limiting screw holes 15 respectively.

[0031] like Figure 4As shown, in one embodiment, in order to ensure the bending effect on both ends of the steel bar, a fixed block 16 is fixed to the telescopic end of the electric telescopic rod 4, and a mounting groove 17 is provided on the inner side of the fixed block 16. A screw rod 18 is rotatably connected to the inner side of the mounting groove 17 through a thread, and the bending block 11 is rotatably connected to the outer side of the screw rod 18 through a thread. By rotating the screw rod 18, the screw rod 18 rotates and drives the bending block 11 to move through thread engagement, and the bending block 11 can be controlled to move to a vertical plane that is not in the same vertical plane as the steel bar, which is simple to operate.

[0032] like Figure 4 As shown, in one embodiment, a handle 19 is fixed to one end of the outer portion of the screw rod 18 to facilitate the rotation of the screw rod 18 .

[0033] like Figure 4 As shown, in one embodiment, in order to ensure the stability of the movement of the rack 10 , a slider 20 is fixed to one side of the rack 10 , and the slider 20 is slidably connected to the inner side of the frame 1 .

[0034] like Figure 4 As shown, in one embodiment, in order to ensure the horizontal movement of the bending block 11, the bending block 11 is slidably connected to the inner side of the mounting groove 17 to play a guiding role.

[0035] The specific working method is as follows: when in use, the steel bar to be bent is passed through the inner sides of the two through grooves 2 and respectively engaged with the outer sides of the two engaging wheels 6. When the middle section of the steel bar needs to be bent, the two rotating blocks 7 are respectively pushed toward one side of the two gears 5. The two rotating blocks 7 slide along the outer sides of the two connecting shafts 3 respectively, and at the same time squeeze the two springs 14. The elastic potential energy of the two springs 14 is utilized to facilitate subsequent resetting. When the two rotating blocks 7 are respectively engaged with one side of the two gears 5, the bolts are respectively rotated and inserted into the inner sides of the two limiting screw holes 15 to limit them so that the two bending wheels 8 will not contact the steel bar during subsequent rotation. The switch of the electric telescopic rod 4 is turned on, the fixed block 16 moves downward, and then the bending block 11 is driven downward to squeeze and bend the steel bar. The operation is simple. When the two ends of the steel bar need to be bent, according to the above principle, the two rotating blocks 7 and the two gears 5 are released. The limit between them, under the elastic potential energy of the two springs 14, the two rotating blocks 7 are reset, and the handle 19 is held to rotate. The rotation of the handle 19 drives the screw rod 18 fixed thereto to rotate, and the rotation of the screw rod 18 drives the bending block 11 to move through the threaded engagement. The bending block 11 is moved to a point where it is not in the same plane with the steel bar, and the switch of the electric telescopic rod 4 is turned on. The telescopic end of the electric telescopic rod 4 extends, driving the rack 10 fixed thereto to move, and the rack 10 is meshed with one of the gears 5. The two gears 5 are meshed, so that the two gears 5 rotate relative to each other. Through the connection of the two plug-in rods 13, the two rotating blocks 7 are driven to follow the two gears 5 to rotate along the outsides of the two connecting shafts 3 respectively, and then the two bending wheels 8 rotate synchronously, and the two ends of the steel bar are bent, which can be bent into a circular ring shape. The operation is simple. Through the above principle, different bending effects of the steel bar can be achieved, thereby improving the practicability of the device.
