Correct operation measures of hydraulic pipe bender

section I: potential hazardous areas on CNC pipe bender

most potential hazardous areas of pipe bender are distributed in:

1 The total movement stroke of the bent arm, which is particularly dangerous between the movement range of the bent arm and the fixed arm and the bent arm

2. Mold movement range

3. Bend the area of the angle selector

4. The moving space for the loading and unloading of pipe fittings and the rotation of pipe fittings in front of the machine head

in these dangerous areas, each one has been defined by a consistent safety sign. Please refer to its description in the danger sign area shown in the drawing of the pipe bender

section II: use of pipe bender

it is extremely important to use pipe bender in a humanized and smart way. The safety of operators and die installers is as important as the service life of the machine. Proper use and maintenance of the machine will increase the service life of the machine. However, incorrect use will lead to accidents and serious risks. The wrong use of pipe bender may not be intentional, but it will accelerate the wear of machine parts and the degradation of various functions

there is a safety guard beside the bending arm of the machine. If a worker enters the action range of the bending arm, the bending arm will stop abruptly at the moment when the bending arm clamps the worker, and the screen will display an alarm to prevent serious injury

when the machine is in an emergency state, you can press the emergency stop button to interrupt the power supply to prevent dangerous events. After the danger is eliminated, you need to restart. Please make sure that the power supply is turned on before restarting

1. The position of the emergency stop button

is on the operation panel: pressing this button will stop the power supply of all motors and servo

2. Avoid overload

misuse of machine equipment will cause overload of machine parts. Excessive load may not be intentional, but it is easy to happen. According to the feedback of the market and the advantages of the product, the torque required for pipe bending is greater than the torque range of the original design of the machine

confirm the load during the operation of the machine to avoid overload of machine components, otherwise it will affect the service life of the machine and the safety of operators

warning! The maximum bending capacity is bendable. The tensile coefficient of general iron pipe is 40kg/cm2, which is the most standard

please be sure to comply with these technical specifications, otherwise the machine will be seriously damaged

3. Safety training

through professional pre job training and assessment, accidental injuries that may occur in the production process can be avoided or minimized. The safety training program must be supervised and guided by leaders and managers. Managers must be sensitive to safe operations in all their work areas

in order to achieve the maximum protection effect, appropriate training is necessary. At ordinary times, employees should be instilled with the safety concept of working environment and machine operation, and pay attention to personal safety awareness with important rules such as mold installation guidance, safety devices and operation methods and personal safety

section III: safety measures for electric power

1 Insulator circuit always exists at the joint connection, do not touch! If an external auxiliary power cord socket has been assembled, it is not allowed to touch it, and only professional personnel are allowed to turn on the power accessories

2. Before using the machine, change the voltage of all transformers to the voltage suitable for the local supply of the machine. Warning! Before the machine is sent from the manufacturer, it should be connected with the main insulation switch in the electrical box

3. The power supply of the machine must be three-phase power supply and grounded in accordance with local power regulations

4. Before any electrical box is opened, the machine must be completely isolated from the power supply. The main switch of the three-phase power supply of the machine must be turned off and clearly marked on the machine and in the operating area of the staff

5. The main power switch must be locked in the off position with a relatively stable device. Please note that! Even if the main insulator is closed, the incoming main line still supplies power

6. The marking of power supply should be displayed on the machine and control box to warn the staff working in the power system

7. Before the main power switch is turned on and the power of the machine is restored, the door of the machine's power control box must be closed tightly

8. The staff doing power maintenance and inspection must be trained in power professional knowledge. Please confirm the standby circuit diagram before maintenance

9. Voltage supply requirements: plus or minus 5% volts

10 Limit switches and other protective equipment shall not be arbitrarily short circuited or bypassed

11. The installation work must comply with the latest national electricity regulations and be completely tested according to their regulations

section 4: safety measures for hydraulic system

1 This pressure can be measured by the pressure gauge equipped with the hydraulic system

2. Do not remove any fittings or equipment of the machine oil pressure system under any circumstances and under any system pressure

3. All high-pressure oil pipes on the machine must be checked regularly to ensure that they are still in a good condition. They should not have any serious abrasion and abrasion. If any high-pressure oil pipe is broken or bruised, please replace it immediately and stop using the machine

4. All oil pressure parts assembled on the machine have been classified to meet the maximum working pressure of the system appearing on the oil pressure circuit. Any increased pressure that will lead to potentially dangerous operating conditions must be avoided

5. When purchasing oil products, please confirm that lubricating oil and hydraulic oil are non-toxic, and only use specific oil products to achieve the specified working state

6. If parts of the body are exposed to organic oils for a long time, the natural oil of the skin itself may be removed, which will lead to gradual dryness and local irritation of the skin. Be sure to wear gloves when contacting hydraulic oil. Under no circumstances should you swallow hydraulic oil

7. When repairing and adding hydraulic oil, if oil remains on the ground, be sure to clean it or pour it into the oil tank

Section V: safety measures for servo driver

servo driver is installed in the electrical control box. A servo driver controls the AC servo motor of each rotatable machine axis, such as feeding shaft and angle shaft. Each servo driver can be checked by its own display to determine that it is effective. If the driver doesn't act or is overloaded, check the display of the driver. At this time, it will not display or send out alarm information. In this case, the machine will not operate

when the servo motor is abnormal, some codes will be displayed on the display of the servo driver to inform of abnormal conditions. If such conditions occur, please refer to the instructions or contact the pipe bender manufacturer

1. Since there is a high-voltage circuit inside the servo driver, please do not touch it during operation. Besides, please do not disassemble or repair the pipe bender unless specified by the manufacturer

2. During a period of time just after the power is cut off, the driver is full of high voltage. If you want to contact the terminal block or the driver, please turn off the power for 5 minutes before operation

3. Do not touch the driver, motor and surrounding machines because the temperature will rise during operation. Especially when the external regenerative resistance is connected, sometimes the rising resistance will reach high temperature, so do not touch it

4. Shortly after the power supply is disconnected, the heat sink and pickup resistance of the drive may reach high temperature, so do not touch it. For a long time, how to test the rubber strength of liquid crystal rubber tensile testing machine? Please be sure to cut off the power supply,

6 when the analysis room is not in use The internal parameters have been tested for safety and should not be changed without consent

from the preparation of aluminum alloy melt to hot rolling to the coil for cold rolling, it is shortened from 20d to 20min7 When the wiring of servo motor is removed, be sure to cut off the power supply

section 6: safety measures for mold installation

mold installation is an extremely important work. The mold installer needs to have the professional knowledge of operating the pipe bending machine and properly adjusting the pipe bending mold to make the tensile testing machine stretch the standard tensile sample at the speed specified in gb/t228 (2) 002 standard, which is very important to the quality of pipe bending

the mold must be suitable for the size of the machine. If the pipe fittings larger than the original value are bent, the excessive load of the machine will lead to the failure of mechanical performance, and may harm the personnel in operation

mold installers must cultivate personal safety awareness, and mold installation must be carried out with a safe attitude. All mold installers should realize the importance of safety and providing a safe operating environment for others when they perform their work

1. Do not place your hands, fingers or any part of your body in the mold operation area when starting the oil pump motor

2. Do not install, adjust or move the mold without reading or understanding the mold installation instructions in the instruction manual

3. Do not wear ties, jewelry or loose clothes when working or close to the machine

4. If the mold is too heavy to be lifted by hand, appropriate mechanical lifting methods should be used. A lifting ring shall be installed on the mold, and the lifting ring shall be used to maintain the stability of the mold parts during the hanging process

5. Before installing the mold, wipe it clean and remove dust, metal chips or other foreign dirt. Otherwise, it will cause mismatching, personal injury or damage to machines and molds

6. In order to carry out different operations, when it is necessary to change the setting of the pipe bender control, please first confirm whether the setting of the selector switch is correct. Before performing the bending work, please test run to make sure that the operation is correct

7. The elbow lubricating oil will make the surrounding area slippery and dirty the mold area. Handle the mold carefully. When bending, insert the end of the pipe coated with absorbent paint into the safe and practical range of the mold, so as to prevent the elbow lubricating oil from dripping on the machine

8. When the pipe bender cannot run or nobody operates, even for a short time, please check the settings of all switches before restarting the machine

section 7: maintenance and repair

in order to maintain the efficiency and safety of the machine, there must be an effective plan for machine inspection and maintenance, which must be implemented in accordance with the regulations

the service life of relays, solenoid valves or other electrical and mechanical parts should be determined by trial use methods, bad environmental conditions and a complete preventive maintenance plan

due to wear or improper maintenance, a part will make mistakes at any time. Frequent inspection and a good preventive maintenance plan can reduce the possibility of mistakes. Parts that are worn or cannot be repaired must be replaced immediately

the clean environment around the machine makes any inspection and maintenance easier. It is also important to keep the floor around the machine clean and free of debris
