Profile Bending Machine

profile bending machine

One .Overview of the main bodyThis machine belongs to the arc mode under three roll profile bending machine, is a special interesting condition will all kinds of profile bending method using a special device, it can be rolled round, spiral workpiece, mould replacement can roll bending Angle steel, flat steel, square steel, channel steel, i-steel, round steel, steel profiles, such as the machine has compact structure, reliable operation, small volume, complete functions, and the economic and practical, Advanced at home and abroadThe profile forming equipment.

Two、technical parameters

Note: The main machine includes a set of molds, and the cost of molds is extra

Three, working principle and structural characteristicsThis machine is a fully hydraulic arc down mode three-roll profile bending machine, with the pre-bending function of profiles, three work rollers are the main driving roller, through the hydraulic motor, gear to achieve, two rolls around the fixed rotation center to do arc lifting movement, work roller on both sides of the roller and the correction guide roller device, It is helpful to ensure the quality of unsymmetrical section (such as Angle steel) profile rolling.The main structure of the machine is composed of bed part, side roller part, supporting roller part, transmission part, electrical part, hydraulic system and mold parts.

1 Bed partThe machine frame IS WELDED BY the whole steel plate, and the stress is removed, so that the machine has enough strength and steel degree to meet the bending of various profiles within the capacity of the machine.

2 Side roller partThe lifting AND lifting of the two lower rollers of the machine is an arc movement mode, which is promoted by the hydraulic cylinder. The two lower rollers can move in an arc around the fixed center, and the lifting and displacements of the two lower rollers are displayed by figures, which is eye-catching and intuitive. Its main components are: lifting cylinder, roller, gear, wring frame, fixed shaft, etc.

3 Roller partThe roller correction roller of this machine has three movements, it can do the lifting movement by itself, can do the arc lifting movement with the lower roller at the same time, can also do the rotation movement at the same time, to ensure the forming quality of the profile in the process of rolling. The supporting roller is installed on the left and right rotating arms, and moves in an arc with the side roller. At the same time, the oil cylinder can be rotated and lifted around the arm at a specified Angle by rotating the oil cylinder and lifting the oil cylinder by the supporting roller. Its main components are: lifting oil cylinder, rotating oil cylinder, supporting roller, correcting roller, and rotating arm.

4 Transmission partThe three rollers of the machine are all active rollers, which are driven by hydraulic motor and transmitted to both sides of the roller through the three-stage gear transmissionThe stage gear drive and the stage chain drive are transmitted to the upper roller. The mechanism has compact structure and less noise. Make the whole machine beautiful appearance.

5 Electrical control systemThe power line of the electrical system uses three-phase 380V, 50HZ AC power supply control circuit, 380V will be converted into 220V power supply through the control transformer, the machine's electrical operation control and display are centralized installed in the electric control cabinet, the function of each operating part is represented by visual symbols. And equipped with mobile operating table.

The control system is composed of Omron programmable controller, MT506 color touch screen display, incremental grating or encoder and low-voltage electrical components. MT506 color touch screen is connected with PLC through a special communication line. Its function is mainly to adjust the status display by touch and control with the function button on the operation panel.

Operation panel button function:1) SB0: emergency stop button (red mushroom shape).2) SB1: The up button is used together with the touch button on the display screen.3) SB2: The down button is used together with the touch button on the display screen.4) SB3: Oil pump starting5), SB4: upper roll left rotation6), SB5: upper roll right rotation7), SB6: upper roll stop and lower roll stop8), SA0: upper roll left and right rotation, linkage selection9) SA1: left roller lifting and lowering options10), SA2: left and right rotation of the left idler11) SA3: Selection of right roller lifting and lowering12), SA4: right roller left rotation, right rotation selection

3.6 Hydraulic SystemThe machine is a fully hydraulic drive open system, rated working pressure 19, 5MPa, using double gear pump, the big pump is used for the rotation of the main transmission system motor, the small pump is used for the lifting of the auxiliary system cylinder, electromagnetic reversing valve, relief valve and electromagnetic relief valve for no-load starting, pressure adjustment, overload unloading, Observe the pressure adjustment range and pressure fluctuation of the system through the shockproof pressure gauge.The system is in the form of button control, and the power of the solenoid directional valve determines the working condition of the actuator (lifting and lifting of oil steel, horseTo the positive and negative rotation), by the hydraulic control check valve to implement pressure protection on the actuator.The WORKING medium OF the system is 46# anti-wear hydraulic oil. The filled hydraulic oil must be clean, free of impurities, and injected from the motor drain portWith the oil. Before starting, pay attention to the motor rotation is consistent with the mark, and the maintenance and maintenance of the hydraulic system shall be carried out in accordance with the relevant regulations.Iv.
