Pipe bending machine is a bending tool with bending function and lifting function .It can be bend a variety of pipe to your desired location. Bending machine has the advantages of reasonable structure, safe use, convenient operation, reasonable prices, rapid assembly and disassembly, also is a tractor serves several purposes ,and many other advantages. In the domestic,hydraulic pipe bender has big share.

　　1.Bending machine working principle and general structure: bending machine generally comprises the electric oil pump (10), high pressure oil pipe (12), fast joint (13), a working oil cylinder (8), a plunger (7), bend parts [including flower plate (3), and lower board (14), die head (4), roll (2) ]. The electric pump outputs pressure oil, then the high pressure oil pipe into the working oil cylinder, high pressure oil to drive the working cylinder piston, to produce thrust, bend pipe through bending parts .

　　2.Bender uses
　　Bending machine suitable for factories, warehouses, docks, construction, railway, automobile, installing the pipeline and repair. Except the bending function, it can unload pipe components ( cylinder ) as a separate hydraulic jacking machine.
Through the above explanation, could understand the bending machine’s working principle ?
