In the maintenance process of the bending machine, the following safety issues need to be paid attention to:

Safety preparations before operation:

The operator must strictly abide by the safe operation procedures of the machine tool worker and wear labor protection articles according to the regulations. This is the basis for ensuring personal safety.

Before starting work, check whether there are foreign objects on the front pallet, rear baffle and slide. If there are foreign objects, they should be thoroughly cleaned up to avoid safety risks.

Check the adhesion and robustness of the upper and lower die, and whether the positioning device meets the requirements of the processing, which is also an important step to ensure the safety of the operation.

Safety matters during operation:

Before starting the bending machine, it is necessary to carefully check whether the motor, switch, line and grounding are normal and firm, and whether the control parts and buttons of the equipment are in the correct position.

After the equipment is started, it should be empty for 1-2 minutes, and the skateboard should be moved 2-3 times for a full trip, so as to observe whether there is abnormal sound or fault, and ensure that everything is normal before it can work.

During operation, the pressed workpiece should be placed in the middle of the upper and lower die and parallel to it, and the pad should be placed smoothly. During the working process of the bending machine, it is forbidden to overhaul or adjust the mold to ensure the safety of operation.

Safety requirements for specific operations:

When it is necessary to press long and large pieces, there should be two (or more) people to operate, to avoid dumping when the workpiece is relaxed due to deformation in the hand, and to prohibit close contact with the pressed workpiece to prevent injury.

When exchanging or pressing the workpiece, the workpiece should be placed in the middle position of the mold, and no bias is allowed. The upper die should be slowly close to the workpiece to prevent the workpiece from suddenly popping out and causing damage.

Daily inspection and maintenance:

In the work, it is necessary to often check whether the stroke of the two cylinders is consistent, otherwise it should be adjusted or reported for repair in time. If the cylinder piston is found to shake or the oil pump screams, the air in the oil line must be removed to ensure the stable operation of the system.

Always pay attention to whether the oil level of the tank is suitable, such as the oil level is too high to check the return pipeline, and adjust the return oil valve, strictly prohibit the oil overflow of the tank, in order to prevent the occurrence of fire and other safety accidents.

Shutdown and shutdown precautions:

After the work is completed, the oil pump and power supply should be turned off to ensure that the equipment is in a safe state.

When adjusting the mold or maintenance, the oil pump must be closed to ensure safety; At the same time, the main power supply should be cut off before the relevant work.

To sum up, the maintenance of the bending machine needs to pay attention to multiple aspects of safety issues, including preparation before operation, specifications in the operation process, requirements for specific operations, daily inspection and maintenance, and safety steps for shutdown and shutdown. Following these safety specifications ensures operator safety and increases the service life of the equipment.
