[0002] The bending device of the steel bar bending machine is mainly composed of a bending disc, a central axis hole, a bending axis hole, etc. The bending disc is the main component that performs the steel bar bending action when the machine rotates. There are several bending axis holes on the bending disc, and the bending pins are inserted into the bending axis holes and fixed by screws. In order to adapt to steel bars of different diameters, the position and size of the bending pins need to be changed;

[0003] The position and size of the bending shaft hole on the traditional bending disk structure are fixed, which is difficult to meet the bending requirements of steel bars of different diameters. For this reason, we proposed an adjustment structure of the bending machine.

The adjustment range is large, and two sets of shaft grooves with different diameters are set on the pendulum block, which correspond to the bending pin with a large diameter and the bending pin with a small diameter respectively, so that the bending pin can be selected according to the needs.
