-How to use the electric hydraulic pipe bender
Tighten the switch of the electric hydraulic pipe bender and support the wheel Apply lubricating grease to the contact area between the mold and the workpiece to be bent.
According to the size of the pipe to be bent, select the corresponding bending mold and install it on the top of the piston rod. Place the corresponding grooves of the two support wheels facing the bending mold. Pay special attention to the support wheels should be placed on the edge of the wing plate. Within the holes of corresponding sizes, the largest size is the outermost hole. And so on. Avoid asymmetry in the position of the two supporting wheels, which may cause damage to the mold and machine parts.
After placing the workpiece, cover the upper wing plate. First use the fast pump to press the bending mold to the workpiece, and then use the slow pump to press the workpiece to the required angle. After bending, turn on the switch, and the working piston will automatically reset. Open the upper wing plate and take out the workpiece.
-Electric hydraulic pipe bending machine precautions: Before using the electric hydraulic pipe bending machine, first check whether the oil in the tank is sufficient. If it is insufficient, fill it up.
Before starting work, the switch must be turned off, otherwise the pressure cannot be turned on, and the refueling plug must be loosened to facilitate ventilation of the fuel tank.
The outer diameter of the bent pipe must fit into the groove of the bending mold. Otherwise, the workpiece will be dented or the mold will be cracked.
The weld seam of the welded pipe should be directly outside or directly inside the bend. During the bending process, the two support wheels must rotate at the same time and the workpiece slides in the groove of the support wheel. If one side does not move, the operation should be stopped.
, Electric hydraulic pipe bending machine should do a good job of cleaning and maintenance of the equipment at ordinary times. The refueling should be clean and must be filtered through a mesh above the mesh. The oil filter device should be cleaned regularly
, Electric hydraulic pipe bending machine usage number Machinery oil.
-Electric hydraulic pipe bending machine wearing parts
In order to facilitate user maintenance, put the electric hydraulic pipe bending machine wearing sealing parts into the spare parts bag.
-Possible faults of the electric hydraulic pipe bender and their troubleshooting methods:
Fault
Cause
Troubleshooting method
After the piston rod extends to a certain length, shake the handle. The neck rod stretches and contracts.
The refueling screw plug is not loosen
Loosen the refueling screw plug
The oil outlet valve port in the pump body is not sealed and the steel ball of the oil outlet valve is not rounded
There is garbage in the oil. Replace clean engine oil and steel balls.
Oil leakage from the piston rods of the large and small pumps
The sealing ring is damaged
Replace the sealing ring in the spare parts bag
Oil leakage from the switch
The pressure ring inside the switch is too large Loose
After removing the limit screw and switch, tighten the pressing ring
and the ejector pin will be weak and cannot work.
The steel ball in the switch is not well sealed. The top of the switch does not hold the steel ball firmly or the steel ball falls off.
Replace the steel ball and tighten the switch. If there is no steel ball, add a steel ball.
, oil leakage from the top of the ejector
The sealing ring at the top of the piston rod is damaged
Replace the . There is garbage on the filter inside the device or there is insufficient oil.
Unscrew the serial numbered parts, clean the mesh body with gasoline and fill it with oil.
, the mold mounting hole is cracked
There is a lateral load when the mold item comes out
For example: the bent workpiece is not in the correct position when it is bent again
Check whether the two supporting wheels are in the right position Symmetrically, apply oil to the joint between the support wheel and the workpiece, and place it in the correct position for the second bend.
The pick-up pump is also called the rising pump and return pump
The steel ball of the oil outlet valve cannot be reset normally
Extend the action rod so that there is pressure on the plunger pump, use the The valve ball can be reset with a few taps.
