Product Introduction

SW Double Bend, and A can rotate 90 degrees inside and outside

Manual, automatic selection and automatic switching

Microcomputer control, Chinese subtitle display, human-machine dialogue operation

Equipped with automatic counting function, it automatically stops when the set quantity is reached

Two sets of machine heads can operate separately or simultaneously, allowing for simultaneous processing of multiple parts, with a cyclic operation and high efficiency

Equipped with a cooling system, it can maintain a constant oil temperature, relatively balanced pressure, and strong bending

Analysis on Troubles

Troubles	Causes	Solution
Press the start button and the motor start working, while oil tank does not pump the oil.	Motor turns in wrong direction.	Adjust the motor connection wire.
The system pressure is not enough at the working mode. The oil cylinder does not work well. The speed is too slow.	1,The oil filter or the pipe is blocked. 2,The overflow valve core blocked.	1,Clear out the block. 2,Recondition the overflow valve.
Normal system pressure but oil cylinder does not work well.	1,Solenoid valve is blocked. 2,Throttling valve flows out too little	1,Recondition the solenoid valve and the throttling valve. 2,Adjust the flow.
The system pressure is unsteady. Abnormal noise. Cylinder works at very low speed.	1,Air has run into the system and the oil level is too low. 2,The interior of the cylinder is grinded and resulted in burs. 3,Poor contact of the solenoid valve.	1,Add the hydraulic fluid. 2,Repair the oil cylinder. 3,Recondition the solenoid valve wiring.
Some functions do not work	1,The relevant electromagnet blocked. 2,The relevant electromagnet malfunctions.	1,Recondition the solenoid valve. 2,Check the electric circuit.
Work in low speed and no pressure.	1,Overflow adjusting pressure is too low. 2,Seal components damaged.	1,Adjust the overflow valve pressure. 2,Change the seal components.
The bent pipe wrinkles along the inside of bend.	1,Dies spoiled. 2,Pressure-exerting die not in full position. 3,Bending radius too small or bad extensibility of the pipe.	Change the dies. Adjust the pressure-exerting die. Expand the bending radius or choose thick wall pipe or use material of good extensibility.
