Composed devices
1.hydraulic entry car
The car can move levelly and vertically, which is convenient for putting the steel coils to the un-coiler.
It is driven vertically by hydraulic pressure and the level movement is driven by cycloid electromotor .
2. Cantilever decoiler
supporting steel rolls and uncoiling.
the core can ensure the expand range φ510 of the coils inner diameter
It adopts the hydraulic oil cylinder to make the decoiler expandable and fit to the inner diameter of coils. It is equipped with the cantilever .
40N.m moment motor drive the coils running and can do forward and reverse running as well as do the decoiling with tension.
3. fourfold pre-leveling machine
It is equipped with the press and pinch device at the entry which is driven by hydraulic.
It is composed of 17 leveling rollers, 2 groups of supporting rollers ,driving device and 2 pinch rollers and frame. Both sides of each rolling wheel is transmitted by needle pins all are the main force rollers.the total quantity of the rollers is 19, the diameter is 55and the distance between the rollers is 60mm, with supporting rollers.
The function of the supporting roller is to balance the leveling rollers force and reduce the friction to the rollers.
The working rollers can be adjusted the gap electrically which is controlled by 2 hand wheel to ensure the leveling quality.
Driving model: all the independent rollers and gear box are driven by 45kw frequency control motor
4. Loop
Function : it is used to eliminate the different speed and make the plates which in wrong rail to back the right way. At first, it is used the oil cylinder to lifting the supporting and transition plates to make the head pass . when working , the transition and supporting plates lift down , the steel plates will be stored in the pit.
5. side guide device
It uses the vertical roller-wheel on the both sides to direct strips into straightening device and cutting machine.
The stand rollers on both sides are adjusted by leadscrew. The range of the width is 500-1250mm
6. servo precision straightening machine
It is controlled by servo electromotor and used to regulate for high speed feed and precise length control
The operation is done at the control table with programmable control.
Drive model:15kw servo motor with precise decelerating transmission and synchronous to transport the belt to feed rollers
7.High speed cutter
shear model: cut from up to down hydraulically which is cooperate with the signal direct from the feeder and shear automatically
Adopt gap adjusting design to cut the materials and can shear 3mm steel plate safely after heat treatment
8. transportation table
Transportation belt is skidproof and wearable
Drive: cooperate with the line speed and is transmitted by 2.2KW frequency control motor
9. hydraulic lifting table
the length of plates can range from 500-4000mm( which can be customized)
The width cab be ranged from 500 to 1250mm.
10. pneumatic stacker device
The plates are piled Pneumatically and PLC controls the lifting.
three 0.75kw motors drag to adjust the width and the length.
It is equipped with the wind device which cooperate with the high pressure fan to prevent the sheets from friction
11. exit coil car
12. hydraulic system
Ensure the using of every hydraulic parts
6.3-16Mp The working pressure of the hydraulic system is 6.3-16Mpa
13. electrical system
Adopt the the PLC control mode ,It is controlled by LCD screen with fixed-length cutting by codes and count automatically .
