Hand wrenches can be used to bend thin steel bars, and clamping bars and wrenches can be used to bend thick steel bars. The workbench and bending machine workbench should be kept level, and all kinds of mandrels and tools should be ready. According to the requirements of the diameter and bending radius of the processed steel bar, install the mandrel, forming shaft, iron retaining shaft or variable retaining frame, and the diameter of the mandrel should be 2.5 times of the diameter of the steel bar. Check that the mandrel, stop and turntable should be free of damage and cracks, and the protective cover should be fastened and reliable. Only after idling can the operation be carried out.

When operating, insert one end of the steel bar to be bent into the gap of the turntable fixing pin, and press the other end against the fuselage fixing pin by hand. Check whether the pin of the fuselage is really installed on the side blocking the steel bar before starting the machine. During operation, it is forbidden to change the mandrel and pin, change the angle and adjust, and it is also forbidden to refuel or clean.

The dimensions of the manual bending tool are as follows: Main dimensions of the manual wrench (mm)

Main dimensions of chuck and wrench (horizontal wrench) (mm)?

Extended data:

The steel bar bending machine belongs to the structural improvement of the steel bar bending machine. Comprises a reducer, a big gear, a small gear and a curved disk surface. The pinion engages with the big gear for secondary deceleration; The big gear always drives the curved disk surface to rotate; The arc-shaped disk surface is provided with a central shaft hole and a plurality of arc-shaped shaft holes; A plurality of positioning shaft holes are respectively arranged on the positioning square rods of the workbench surface.

Because the two-stage brake motor is directly connected with the reducer to perform the first-stage deceleration, the input-output revolution ratio is accurate, the bending speed is stable and accurate, the speed can be automatically controlled by electronic control, and the brake can ensure the bending angle. The steel bar is bent in two directions by the forward and reverse rotation of the motor. The central shaft can be replaced for easy maintenance. Intelligent control can be used.
