What are the safety operating procedures for steel bar bending machines?
1. The workbench and bending machine table should be kept level, and various mandrels and tools should be prepared.
2. Install the core shaft, forming shaft, iron shaft or variable gear frame according to the requirements of the diameter and bending radius of the processed steel bars. The diameter of the core shaft should be 2.5 times the diameter of the steel bar.
3. Check that the core shaft, block and turntable are free of damage and cracks, and that the protective cover is securely fastened. After idling, confirm that they are normal before operation.
4. During operation, insert the end of the steel bar to be bent into the gap of the turntable fixing pin, and the other end close to the machine body fixing pin, and press it tightly with your hand. Check that the machine body pin is indeed installed on the side blocking the steel bar before starting.
5. During operation, it is strictly forbidden to replace the core shaft, pins, change the angle and make adjustments, and it is also forbidden to refuel or clean.
6. When bending steel bars, it is strictly forbidden to exceed the machine’s regulations on diameter, number of bars and mechanical speed.
7. It is strictly forbidden to stand on the side of the machine body without a fixed pin within the bending radius of the steel bar. The bent semi-finished products should be stacked neatly, and the hooks should not be facing upwards.
8. When performing maintenance or reversing the turntable, the machine must be stopped and the power must be turned off.
