1.Working mechanism of steel bar bending machine
Steel bar bending machine, one of the rebar processing machinery. The working mechanism is a horizontal working disc that rotates on a vertical axis. The steel bar is placed at the dotted line in the figure, the supporting pin is fixed on the machine tool, the center pin and the bending pin are installed on the working disc, and the disc rotates When the steel bar is bent. In order to bend steel bars of various diameters, there are several holes on the working plate for inserting and pressing the bending pins, and the center pins of different diameters can also be replaced accordingly.
2.Operating procedures of steel bar bending machine
1）Check whether the mechanical performance is good, the workbench and the steel bar bending machine table are kept level; and prepare various mandrel tool blocks.
2）According to the diameter of the processed steel bar and the requirements of the steel bar bending machine, install the mandrel, forming shaft, iron stop shaft or variable stop. The diameter of the mandrel should be 2.5 times the diameter of the steel bar.
3）Check the mandrel, the stopper, and the turntable of Steel bar bending machine should be free from damage and cracks, and the protective cover should be fastened and reliable, and the operation can only be performed after the empty machine is running normally.
4）During operation, insert one end of the steel bar that needs to be bent into the gap provided by the turntable, and the other end is tightly fixed against the body and pressed by hand to check the fixation of the body.It can be moved only when it is installed on the side that blocks the steel bars.
5）It is strictly forbidden to replace the mandrel, change the angle, and adjust the speed during the operation, and do not add oil or remove it.
6）When bending steel bars, it is strictly forbidden to process steel bars that exceed the diameter, number of bars and mechanical speed specified by the steel bar bending machine.
7）When bending high-hardness or low-alloy steel bars, the maximum limit diameter should be changed according to the mechanical nameplate, and the corresponding mandrel should be exchanged.
8）It is strictly forbidden to stand on the side of the fuselage that is not fixed within the working radius of the bent steel bars. The bent semi-finished products should be stacked neatly, and the hooks should not face upwards.
9）When the turntable changes direction, it must be done after stopping.
10）The work is completed, the site is cleaned, the steel bar bending machine is maintained, and the lock box is powered off.
