The machine is composed by machine body,side roller,support roller, The transmission part,the electrical part and hydraulic parts and mold etc..
The machine is curved three-roller bending machine and has the pre-bending function.The three working roller act as the main-drive rollers through the hydraulic motor,gears .The two bottom roller make vertical movement by hydraulic drive. The two bottom rollers can do arc lifting movement by fixed center of rotation.In the two sides of working roller there are support roller and correction of guide roller ,will be useful in quality control of Asymmetrical section bending(like steel angle).
The support roller and correction roller has three movement:1.vertical movement.2. arc lifting movement with the lower roller synchronously. 3.rotary movement synchronously to guarantee the molding quality in the process of bending.The two lower rollers's vertical movement can be displayed by digital , visual.There are independent operational table ,easy in operation.The machine body is steel welded ,and through annealing treatment to reduce innerstress. Side roller is equipped in the machines' cavity,through the two sides roller cylinder,they can make curved movement along the curved manger by middle axis. Support roller is equipped the left-right rotary hand,and can do curved movement with the side roller.At the same time can do fixed angle rotary and vertical movement through support roller rotary cylinder and support roller cylinder. The vertical movement of the side roller has the digital display ,easy in operation.The whole machine has enough strength and stiffness and can fulfill the needs of bending in all kinds of range. It is possible to bend angle steel,flat steel,square steel,U steel, style steel ,round bar,steel tube.The machine has advantaged structure,reliable in working,small in volume,and combined structure,it is the advanced forming machine and widely used.
Machine driven system
The machine's three rollers are all main-driven rollers and driven by hydraulic motor, through three calss gear and transfer to two side rollers,through two class gear transfer and first class chain to the upper roller.
the function of the machine
The machine is three roller all driven ,and can arrange the pre-bending of the steel,through correction supporting roller,can correct the contort in the process.
The machine working range
The basic parameter in the parameter list is the max. reasonable working capability with good economic achievement ,the other type like round bar,sqare bar,steel tube,if the section modulus is less than 16CM3 ,can be bended through related molds.
the working process
Can arrange the pre-bending in the machine,the roller process as below.
