There are three common types of press brakes: hydraulic press brakes, CNC press brakes and manual press brakes. Generally, the press brake is composed of the following parts, including a bracket, a worktable, a tensioning plate and a base. There are some things that need to be paid attention to when operating a press brake, so what are the specifics?
The precautions for the safe operation of the press brake are:
1) Strictly abide by the safety operation procedures of machine tool workers and wear labor protection equipment according to the regulations.
2) Before starting, it is necessary to carefully check whether the motor, switch, circuit and grounding are normal and firm, and check that the operating parts and buttons of the equipment are stuck in the correct position.
3) Check the coincidence and firmness of the upper and lower molds; Check whether each positioning device meets the requirements to be processed.
4) When working, one person should be under unified command, so that the operator and the feeding and pressing personnel cooperate closely to ensure that the cooperating personnel are in a safe position to send out the bending signal.
5) When the machine tool is working, no one is allowed to stand at the rear of the machine tool.
6) It is strictly forbidden to press and fold the sheet at one end alone.
7) If the workpiece or mold is found to be improper during operation, it should be stopped for correction, and it is strictly forbidden to use hand correction during operation to prevent hand injury.
8) It is forbidden to fold ultra-thick iron plates or quenched steel plates, alloy steels, square steels and sheets that exceed the performance of the sheet metal bending machine, so as not to damage the machine tool.
9) Stop the machine immediately in case of abnormality, check the cause and eliminate it in time.
10) Before shutting down, place wooden blocks on the lower dies below the oil cylinders on both sides and lower the upper slide plate to the wooden blocks.
11) Exit the control system program first, and then cut off the power supply.
