What's the Main Structure and Function Indruction of RUIHUI Coil Handing Line?

RUIHUI Main Structure and Function indruction of the Coil Handling Line

1.Trolley

Function:It is used to smoothly transfer the coil to the mandrel. When coiling and?feeding, it is used to lift the material head?enter the straightener. The trolley is equipped with a coil anti-dumping baffle,when transfer small materials can??effectively prevent the coil.

1.1Trolley Drive : Hydraulic Motor(Throttle valve adjustment speed)

1.2 Trolley Lifting Drive：Hydraulic cylinder(The pressure control valve can run smoothly when loading)

1.3 Trolley Mode ： Rollers?and the surface is covered with rubber.

1.4 Design Coil Weight：7000-10000Kg

2 .Decoiler

Function:The decoiler is put coil fixed on the mandrel enlarge shrinks?parts,support the coil I.D support units,through the ring in the operation of the automatic control instruction for mandrel intermittent rotation decoiler feeding.This includes mandrel expansion , pressure arm,?limiting wheel and a material ring control.

2.1 Expansion Mode：Hydraulic connecting rod type expansion

2.2 Mandrel Expansion Range：φ480 ～Φ520（mm）；

2.3 Mandrel Motor Drive：AC motor ( Include converter )

2.4 Mandrel Braking：Pneumatic disc brake??

2.5 Pressure Arm：Pressure arm is above the mandrel.The coil is compressed while preventing the roll from loosening after the belt is removed, preventing the roll from spreading during automatic operation.

2.5 Pressure roller?Drive Mode：AC motor with frequency converter

2.6 The action mode of the press arm: pneumatic drive, can be turned on and off manually, and can be selected as 'use' or 'not used' during automatic operation.

2.7 Pressure roller speed adjustment mode: The potentiometer feedback signal is changed by the angle change of the pressure arm to adjust the speed.

2.8 Pressuring Wheel：PU rubber wheel

2.9 Limit wheel: Located at the upper right of the decoiler, the wheel surface of the ?limit wheel is close to the side of the coil. The wheel has no power and can rotate with any force from the outside. It is used to prevent the belt from slipping during coiling.

3.0 Limit wheel surface treatment: high frequency plus phosphating anti-rust treatment

3.1 Limit wheel action: The cylinder is driven to open and close the limit wheel. The inner limit wheel does not open and close. It only moves in the width direction of the roll. The action of the outer limit wheel is only manual operation of the touch screen. Before the automatic operation. It must be turned off to meet pre-operational safety conditions.

3.2 Track adjustment: Two wheel bodies can be adjusted independently,?handwheel + screw drive, scale on the side of the slide rail for position reference

?3.3 Material ring Control:The infrared photoelectric sensor switch under the pressuring arm brings feedback signal to control the start and stop of the mandrel when the material arc hangs, to ensure a reasonable buffer material arc between the decoiler and straightener feeder.

?3.?Entrance Device

Function description: When feeding, the upper roller can be manually opened and closed. With the trolley, the material can be clamped smoothly, easily and safely, and the material is led from the decoiler?to the flattening wheel.

3.1Feeding swing arm drive: Hydraulic drive, touch screen jog?button operation

3.2 Feeding?roller drive: gear transmission

3.3 Feeding roller: 2, the surface is plowed and blasted with hard chrome, HRC60±2

4.Straightener Feeder

Function: This mechanism is mainly used to correct the coil (length L direction) to make the surface flat, and to feed the material into the press according to the?set length and speed.

4.1 Drive Mode：AC Servo Motor

4.2 Feeding Precision：±0.3mm/m～0.5mm/m

4.3 Straightening Roller：7 PCS（up 4?down 3）?Surface thickening electroplating?hard chromium grinding treatment, HRC60±2

4.4 Direction Feeding Rollers：1 PCS, Surface thickening electroplating hard chromium grinding treatment, HRC60±2 . When the head of material will be change up or down, then it can adjust through the height of rollers.

4.5 Auxiliary roller：2 columns above and below, surface thickened plating hard chrome grinding treatment, HRC60±2

4.6 Feeding Rollers : 2 PCS, Down rollers surface sandblasted hard chrome. HRC60±2.

4.7 All Straightening Rollers Material：High carbon chromium bearing steel

4.8 Straightening Performance Adjustment：Hand wheel mode

4.9 Straightening Performance Show：Dial needle mode

5.0 Roller Drive：Side gear drive,all gears are made of nitrided hardened 6-level precision standard

5.Oiling Device and Supporting Device

Function: The oiling device can oil the material two sides, and the oiling time?can be adjustment.Remaining oil can be recycled and reused

Oiling Rollers Material：Wool felt wheel

Oiling Volume : 20L

Function:The Fulai wheel is installed on the pallet to ensure reliable?transmission of the belt between the press and the die.
