2, Functional description of each part:
1. Unwinding section:
1. The unwinding adopts a shaftless hydraulic cone top, which is convenient for single person operation. Adopting a special conical top form, it does not damage the inner wall of the pipe core. The 3-inch and 6-inch mechanical expansion sleeve locking devices are sturdy and durable. The left and right clamping arms are hydraulically controlled by a dovetail groove linear guide rail. Two hydraulic clamping cylinders, left to right, separate simultaneously, making clamping operation extremely convenient.
2. Two hydraulic powered loading and unloading oil cylinders can withstand a weight of 4.5 tons of raw materials, saving manpower and shortening loading and unloading time.
3. The unwinding diameter is automatically detected by the proximity switch at the unwinding transmission shaft, and there is no need to input material thickness. The residual unwinding diameter can be set to automatically slow down and stop, making it easy to receive the next roll of material. The unwinding tension adopts a sensor closed-loop automatic taper tension control mode through Siemens PLC.
4. Equipped with a mechanism for manually adjusting the release and tightening edges, with an adjustment range of ± 20mm.
5. The material is automatically corrected by the automatic deviation correction system. The entire frame adopts a guide rail type left and right movement, and the moving part adopts a threaded screw rod, which is pushed left and right by a servo motor to achieve automatic deviation correction.
8. The unwinding adopts pneumatic brakes.
It should be controlled by SMC precision proportional valve.
4, Host part:
1. The rack adopts 80 # high-quality castings in a frame structure, and the entire machine is supported by seamless hollow steel pipes. The horizontal and straight beams are segmented in the middle for easy disassembly and transportation.
2. The host adopts a combination of servo motor and synchronous wheel speed ratio for transmission.
3. The traction device adopts active traction and pneumatic compression method. The servo motor drives the mirror roller to actively pull.
4. The entire machine adopts closed-loop servo motor control.
5, Roll up section:
1. The winding adopts a dual structure of surface winding and center winding, with front and rear winding in the form of A/B axis winding. The motor drives the reducer to wind (or single axis rewinding is also possible)
2. The winding mechanical arm adopts an imported dovetail groove linear guide rail structure form
3. Principle of surface winding form, with the winding shaft tightly attached to the steel shaft for synchronous winding (the steel shaft is driven passively)
4. Each winding shaft is driven by a 22kw servo motor, and the winding tension is adjusted based on the current material winding diameter by Siemens PLC automatic control frequency converter to adjust the tension of the expansion shaft, so that there is no thickness factor in multiple cut materials, and all coil end faces are flat.
The flatness of the disc surface is freely selected by switching between pneumatic pressure and self weight pressure, and the tightness of the inner and outer layers of the finished coil is controllable. As the winding diameter continues to increase, Siemens automatically controls the speed of the winding servo motor by PLC, greatly extending the service life of the servo motor.
5. When single axis rewinding is required, the full axis tension can also be selected on the touch screen, and the winding servo motor is used as the rotating cone control mode.
6. Winding and unloading form: hydraulic automatic unloading
7. Waste edge recycling device: The edge collection device collects waste edges
