Steel bar bending machine safety operation procedures

1. The workbench and bending machine table should be kept level, and various mandrels and tools should be prepared.

2. According to the requirements of the diameter and bending radius of the processed steel bar, install the mandrel and the forming shaft, the iron retaining shaft or the variable retaining frame of the corresponding specifications. The diameter of the mandrel should be 2.5 times the diameter of the steel bar, and the iron retaining shaft should have the shaft. set.

3. The diameter and strength of the retaining iron shaft shall not be less than the diameter and strength of the bent steel bar. Non-straight steel bars shall not be bent on the bending machine.

4. Check and confirm that the mandrel, the iron retaining shaft, the turntable, etc. are free from damage and cracks. The protective cover is securely fastened and can be operated normally after being idling.

5. During operation, insert one end of the steel bar into the gap of the fixed pin of the turntable, and the other end is close to the fixing pin of the fuselage, and press it by hand to check that the pin of the fuselage is indeed placed on the side of the bar to be activated. . When processing long steel bars, there should be special personnel to help, and follow the instructions of the operators, and do not push and pull at will.

6. During the operation of the steel bar bending machine, it is strictly forbidden to replace the mandrel, the pin and the angle of change and adjustment, and it is also not allowed to refuel or clean.

7. Wear protective goggles when bending steel bars that have not been cold drawn or with scale.

8. When bending high-strength or low-alloy steel bars, the maximum allowable diameter shall be converted according to the mechanical nameplate and the corresponding mandrel shall be exchanged.

9. It is strictly forbidden to stand on the side of the bending radius of the working radius where the fuselage does not have a fixed pin. The bent semi-finished products should be stacked neatly and the hooks must not face upwards.

10. It is strictly forbidden to bend the steel bars exceeding the diameter specified on the mechanical nameplate.

11. When repairing or turning the turntable, it must be done after the power is turned off.

12. After the operation, the rust and debris in the turntable and the inserted hole should be removed in time.
