• Q Seriously in operating the hydraulic tube bending machine

    A 1. The hydraulic system of the machine tool adopts YA-N32 ordinary hydraulic oil (the original brand No. 20), which is replaced once a year under normal circumstances, and the oil filter must be cleaned at the same time.
    2. The pressure of the hydraulic system cannot be greater than 14Mpa.
    3. When manually adjusting the speed of the side pushing cylinder, the rotating arm should be adjusted when it is rotated to ≥900. The adjustment speed is synchronized with the linear speed of the edge of the rotating elbow mold. It is forbidden to push the side pushing faster than the line of the edge of the rotating mold in the manual state. speed.
    4. In automatic operation in the core bending mode, before the bending arm returns, the operator must ensure that the core head is in the tube, or ensure that the mandrel is not blocked when the bending arm returns, otherwise, the core head or core rod may be Bend or break.

  • Q which oil is used in hydraulic pipe bending machine?

    A For the JHPB-20 hydraulic bender it is usually recommended to use 820 ml of ISO VG 22 or ISO VG 32 hydraulic oil, for the JHPB-30 it is recommended to use 1700 ml. If necessary, lubricate lightly on all moving parts.
  • Q How do you use a pipe bender safely?

    Safety Measures While Using Hydraulic Pipe Benders:
    Check the pipe bender thoroughly
    Make sure that the roller shafts are properly pinned, prior to using the pipe
    The pipe should be cleaned regularly, so that its performance is not lowered.
  • Q Do it carefully before operation the hydraulic pipe bender

    A 1. The machine tool must be well grounded, 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 specified range, plug-ins can not be plugged in and out of the plug when power is on, and the control circuit cannot be tested with a megohmmeter, otherwise the device 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. Proximity switches, encoders, etc. cannot be hit by hard objects.
    4. Do not hit the display unit with sharp objects.
