[0002] The rebar bending machine is one of the rebar processing machines. The working mechanism is a horizontal working disc rotating on a vertical axis. The supporting baffle is fixed on the machine tool. The center pin and the bending pin are installed on the working disc. The rebar is bent when the disc rotates.

[0026] In this embodiment, the mounting mechanism 7 includes a mounting block 71, the upper end of the mounting block 71 is fixedly connected to a bending pin 72, the inner left and right parts of the mounting block 71 are both provided with movable grooves 73, the inner walls of the two movable grooves 73 are both fixedly connected to springs 74, the ends of the two springs 74 away from the inner walls of the movable grooves 73 are both fixedly connected to movable sheets 75, the ends of the two movable sheets 75 away from the springs 74 are both fixedly connected to limited insertion rods 76, the diameter of the mounting block 71 is the same as the diameter of the mounting groove 5, and the mounting block 71 is The mounting groove 5 is snap-fitted and connected, and the outer surface of the bending pin 72 does not contact the center pin 3. The two movable plates 75 are respectively located inside the two movable grooves 73, and the two limit rods 76 are respectively inserted and connected with the two limit holes 6 at one end away from the movable plate 75. The mounting block 71 is snap-fitted into the mounting groove 5, so that the two limit rods 76 are respectively popped out from the two limit holes 6 under the elastic reset of the spring 74, so that the bending pin 72 can be easily installed on the working disc 2, and the bending pins 72 of different diameters can be easily replaced.

[0027] In this embodiment, the fixing mechanism 9 includes a connecting tube 91, and a mounting plate 92 is fixedly connected to the right part of the outer surface of the connecting tube 91, a screw rod 93 is inserted and connected to the lower end of the connecting tube 91, and a handle 94 is fixedly connected to the lower end of the screw rod 93, and an anti-slip sleeve 95 is fixedly connected to the outer surface of the handle 94, and a limiting foot pad 96 is fixedly connected to the lower end of the handle 94.

At the same time, before the steel bar bending machine is used, by holding the handle 94 and turning it, the screw 93 will rotate in the connecting tube 91, and then the limit foot pad 96 will move downward so that it fits tightly with the ground. The entire steel bar bending machine is firmly limited and fixed at the place of use, effectively preventing accidental movement or shaking during the bending process, reducing safety risks caused by instability, and ensuring the personal safety of operators. At the same time, stable limit fixation can also make the operation process smoother, reduce pauses and adjustment time caused by factors such as machine shaking, and thus improve work efficiency.
