[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 3 , in this embodiment, a numerically controlled bending machine with adjustable bending degree is provided, including a fixed seat 1. One end of the fixed seat 1 is rotatably connected to a rotating seat 2. A limiting groove 21 is installed on the rotating seat 2. A pressing groove 22 is installed on the rotating seat 2 on one side of the limiting groove 21. A gear 23 is fixedly connected between the rotating seats 2. One side of the fixed seat 1 is fixedly installed with an electric telescopic rod 41. One end of the electric telescopic rod 41 is installed with a connecting plate 42. A rack 4 is installed on the connecting plate 42. The rack 4 is located on one side of the gear 23 and meshes with the gear 23;

[0022] One side of the fixed seat 1 is rotatably connected with a lead screw 5 below the electric telescopic rod 41. An adjusting mechanism 6 is arranged on the lead screw 5, and the adjusting mechanism 6 is used to limit the working stroke of the electric telescopic rod 41.

[0023] During use, place the steel bar on the fixed seat 1. One end of the steel bar passes through the limiting groove 21 and the pressing groove 22. The steel bar is pressed against the limiting groove 21 through the pressing groove 22. With the design of the fixed seat 1 and the rotating seat 2, as the electric telescopic rod 41 shortens, one end of the electric telescopic rod 41 drives the rack 4 to move, and the movement of the rack 4 drives the gear 23 to rotate. After the gear 23 rotates, it drives the rotating seat 2 to rotate. During the rotation of the rotating seat 2, the steel bars on the upper and lower sides can be bent simultaneously, thus effectively improving the bending efficiency. By controlling the moving distance of the telescopic rod 41, the rotation angle of the gear 23 can be changed, and thus the bending angle of the rotating seat 2 on the steel bar can be changed.

[0024] With the design of the moving seat 61, the telescopic distance of the electric telescopic rod 41 is limited by the moving seat 61, so as to avoid the bent steel bar exceeding the required bending angle when the steel bar is bent, and thus avoid the steel bar being over-bent.

[0025] In a further embodiment, refer to Figures 1 to 2 that an expansion link is installed on the rotating seat 2, and the expansion link is fixedly connected with the pressing groove 22. When the expansion link extends, one end of the expansion link drives the pressing groove 22 to move, and the pressing groove 22 thus approaches the limiting groove 21, so as to press one end of the steel bar against the limiting groove 21.

[0026] In a further embodiment, refer to Figure 1 、 3 that the adjusting mechanism 6 includes a moving seat 61. A fixed electrode plate 63 is fixedly connected above the moving seat 61. A moving electrode plate 62 is slidably connected to one side of the fixed electrode plate 63 on the moving seat 61. Coil windings 64 are arranged on one side of the fixed electrode plate 63 and the moving electrode plate 62. The moving electrode plate 62 can be separated from the fixed electrode plate 63, and the upper end of the moving electrode plate 62 is on the movement track of the connecting plate 42. The electric telescopic rod 41, the power supply, the moving electrode plate 62 and the fixed electrode plate 63 form a series circuit, so that when the moving electrode plate 62 is separated from the fixed electrode plate 63, the electric telescopic rod 41 is powered off. By rotating the lead screw 5, the moving seat 61 is driven to move, and the moving seat 61 drives the moving electrode plate 62 to move together, thus changing the distance between the moving electrode plate 62 and the connecting plate 42. After the connecting plate 42 moves, if it exceeds the maximum angle of the steel bar bending, it will touch the moving electrode plate 62, so that the electric telescopic rod 41 is powered off, thus avoiding driving the rack 4 to continue moving, and thus avoiding bending the steel bar beyond the desired angle.

[0027] In a further embodiment, refer to Figure 3, a spring 65 is provided between the moving plate 62 and the moving seat 61 on the moving seat 61. The spring 65 can reset after the moving plate 62 loses its restraint, and the moving plate 62 resets and contacts the fixed plate 63 again, so that the electric telescopic rod 41 is energized again.

[0028] In a further embodiment, referring to Figure 2 , a slotted groove 3 is provided on one side of the fixed seat 1, and limiting holes are provided inside the slotted groove 3 and above the fixed seat 1. Through the slotted groove 3, the bending process of the steel bar located below can be observed, so as to avoid being unable to remove the lower steel bar when a failure occurs. The steel bar that can pass through the limiting hole is limited, so that it will not rotate together during the bending process.

[0029] In a further embodiment, referring to Figure 1 , a movable groove is provided on one side of the fixed seat 1, and the movable groove coincides with the moving track of the rack 4. The movable groove provides space for the movement of the rack 4, so that the gear 23 can have a smaller diameter, so that the rack 4 can have a shorter length, thereby reducing the overall length of the equipment and reducing the occupied space.

[0030] In a further embodiment, referring to Figure 1 , the lead screw 5 is connected with a driving mechanism, and the lead screw 5 is driven to rotate by the driving mechanism. The driving mechanism is a motor. By driving the lead screw 5 to rotate through the motor, the rotation of the lead screw 5 can be controlled by a controller or the like, so as to conveniently position the moving seat 61.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
