The correct operation of the hydraulic pipe bender guarantees the safety of the man and the machine, so how to operate the hydraulic pipe bender correctly? What are the precautions for the operation of the hydraulic pipe bender?


1. The machine tool must be grounded well, and the wire shall not be less than 4mm2 copper soft wire. It is not allowed to connect to a power supply voltage exceeding the regulated scale, plug-ins cannot be plugged in and out of power, and the control circuit cannot be tested with a megohmmeter, otherwise the equipment may be damaged.
2. When plugging and unplugging the connector, do not pull the wire or cable to prevent the welding from pulling off.
3. Close to the switch, encoder, etc. cannot be hit with hard objects.
4. Don't knock the display unit with sharp objects.
5. The electrical box must be placed in a ventilated place to prevent working in dust and corrosive gases.
6. It is not allowed to install or change the input and output terminals of the PC without permission.
7. It is necessary to recognize the rotation of the motor from the beginning when changing the power supply of the machine tool.
8. The machine tool should be kept clean, and extra care should be taken that there should be no foreign objects in the sliding grooves such as clamping blocks and sliding blocks.
9. Add lubricating oil to the chain and other sliding parts regularly.
10. It is necessary to disconnect the power supply during cleaning and maintenance.
11. Preparation before driving: Check whether the oil level of the fuel tank reaches the oil level line, refuel at each smooth point, start to acknowledge the motor steering, check whether the oil pump has abnormal sound, and check whether the hydraulic system is leaking after starting (viewpoint encoder is not Refueling is allowed);
12. Pressure adjustment: Use electromagnetic overflow valve to adjust the pressure to ensure that the system pressure reaches the required operating pressure, usually not higher than 12.5Mpa.
13. Mold adjustment: mold device, mold and clamping block are required to be centered, clamping block can be adjusted by bolts; booster block and mold are centered, booster block is adjustable; core head and mold are centered, loosen the core head frame Bolt, tighten the bolt after adjusting the middle.

Do it carefully in the operation of the hydraulic pipe bender
1. When the machine tool is started, be careful not to enter the scale swept by the rotating arm.
2. When the machine tool is operating, all personnel shall be prevented from entering the space scale swept by the rotating arm and pipe fittings!
3. YA-N32 normal hydraulic oil (original trademark No. 20) is selected for the hydraulic system of the machine tool. Under normal circumstances, it is replaced once a year, and the oil filter must be cleaned together.
4. When adjusting the machine tool (mold), the adjuster should press the button to make the adjustment. It is never allowed for one person to adjust on the machine tool and the other person to operate on the control cabinet.
5. The core rod should be removed when adjusting the machine tool or driving an empty car.
6. The pressure of the hydraulic system cannot be greater than 14Mpa.
7. When manually adjusting the speed of the side pushing cylinder, the rotating arm should be adjusted when it rotates to ≥900. The adjustment speed is synchronized with the line speed of the edge of the rotating arm transitioning elbow mold to prevent the side pushing speed greater than the line of the rotating mold edge under manual conditions. speed.
8. Generally, check the tightness of the chain after using the machine for a period of time, and insist on the tightness of the upper and lower chains.
9. During active operation, in the bending mode with core, before the bending arm returns, the operator must ensure that the core head is inside the tube, or ensure that the mandrel does not obstruct the appearance when the bending arm returns, otherwise, the core head or the core rod can be able to Be bent or broken.
