Product Description
Trough rail cold bending machine (bending machine) is a new type of semi-automatic steel arch bending machine product. Using a hydraulic system, it has the characteristics of stable transmission and high pressure. It is mainly used in coal mines, tunnels, subways, hydropower stations, steel structures, underground caverns, etc. H-shaped steel, round pipes, I-beams, track steel, channel steel, angle steel, U Section steel, miner steel, etc. Bend of profile.
System introduce
1.Mechanical system Mechanical system uses cycloidal pinwheel The reducer directly drives the roller to rotate. The speed is 11rpm, in order to realize the two rollers Synchronization, using two motors to start at the same time Now synchronized, in order to meet the requirements of working conditions, you can Carry out forward and reverse operation.
2.ydraulic system The system uses a manual reversing valve Reverse the direction of the oil pump to realize the movement of the oil cylinder Forward and reverse movement. A one-way throttle valve is used to adjust the movement speed of the oil cylinder, and a two-way hydraulic control one-way valve is used to control the oil cylinder. When the reversing valve is in the neutral position, the system is unloaded, effectively preventing the system from heating up.
3.Electrical system The electrical system mainly controls the oil pump motor and traveling roller motor. The traveling motor is equipped with forward and reverse rotation. Control and overload protection. When the return oil filter is clogged and the filter element needs to be replaced, the filter clogged indicator light will illuminate. The filter element needs to be replaced from time to time. There is an air switch (main switch) in the main oil return line to effectively protect the entire system.
