At present, domestic low-grade and economical pipe bending machines have been well applied in domestic pipe bending machine manufacturers, and some medium-grade and popular CNC pipe bending machines have strong market competitiveness in terms of function, performance and reliability. However, compared with some foreign advanced products, there is still a large gap in medium and high-grade NC pipe bending machines. This is because advanced industrial countries such as Europe, the United States and Japan successively completed the industrial process of NC pipe bending machines in the 1980s. Some famous pipe bending machine companies are committed to scientific and technological innovation and research and development of new products, guiding the technical development of NC pipe bending machines.
There are certain methods when using the pipe bending machine mold. Only by grasping its operation method can we make full use of the various convenient and fast benefits brought by the pipe bending machine mold.
1、 When using the die of the pipe bending machine, refer to the use imitation sheet of the electric oil pump.
2、 When using the pipe bending machine die, first screw the working oil cylinder into the internal thread of the square stop, so that the wheel installed on the support at the rear end of the oil cylinder is downward.
3、 Select the die head according to the outer diameter of the bent pipe, put it on the plunger, put the corresponding groove of the two roller shafts towards the die head, and then put it into the flower plate hole of the corresponding size, then cover the upper flower plate, insert the bent pipe into the groove, then pull the flow part of the quick connector at the end of the high-pressure oil pipe backward and put it on the joint of the working oil cylinder, and tighten the oil drain screw on the electric oil pump, Then bend the pipe. After bending, loosen the oil drain screw and the plunger will reset automatically.
There are certain risk factors in the use of pipe bending machine die: it is dangerous between the flow range of bending arm and fixed arm and bending arm, the area of bending angle selector is dangerous, and the movement space of pipe fitting loading and unloading and pipe fitting rotation in front of the machine head is dangerous. Therefore, through certain research, we get the safe way to use the die of the pipe bending machine: set the emergency stop button, and press this button will stop the power supply of all motors and servo. Avoid overloading and abusing the pipe bending machine mold, and confirm the load during the operation of the machine, so as to avoid overload of machine components, otherwise it will affect the service life of the pipe bending machine mold and the safety of operators. The maximum bending capacity is the tensile coefficient of bendable general iron pipe in the scale of 40kg / cm2.
Professional pre job training and assessment can avoid the possible accidental injury in the production process or reduce it to a low degree. At ordinary times, employees should pay attention to the safety concept of working environment and machine operation, and put important rules such as mold installation guidance, safety devices and operation methods and personal safety. There is always a connector on the insulator circuit, and it is not allowed to touch the connection. Only professional staff are allowed to turn on the power accessories. Before using the machine, change the voltage of all transformers to the voltage suitable for the local supply of the machine. The power supply of pipe bending machine mould must be three-phase power supply and grounded in accordance with local power regulations. The power supply must be clearly marked.
