J16 Reinforced Angle Stiffener Plate Straightening Machine for Shipbuilding

A. Function, Strong Points and Application of J16 Reinforced Angle Stiffener Plate Straightening Machine:

1. Applicable Background and Function of Reinforced Angle Ribbed Plate Straightening Machine:

1) In Shipbuilding/ Bridge/ Port Machinery industries, ribbed plates are often used to strengthen mechanical body of finished construction;

2) These ribbed plates are fabricated from several pieces (Usually 3~ 6 pieces) of Angle Steels onto a piece of large carbon steel plate;

3) After being fabricated, Angle Steels on stiffening plates easily bulge up, making surface of the entire plate unit uneven;

4) Machine Function: Wuxi JACK featured product: J models Angle Rib Plate Straightening Machine is for levelling the above mentioned upturned Angle Steels on plate units:

2. Advantages of Wuxi JACK Reinforced Angle Stiffening Plate Straightening Machine:

1) Highly Automation:  The entire operation can be managed with easy job. Except stiffener plate loading in and out, all the remaining jobs are processed automatically, including straightening ram displacement control;

2) Precise Position of Straightening Rollers:

a) Position of fabricated Angle Steels onto plate differs, within certain variation range of 450~ 600mm;

b) Correspondingly, during operation of Angle stiffening plate straightening, straightening units need to be moved laterally, to aim on the Angle Steels precisely;

c) Such horizontal movement displacement is managed with closed loop control, and detected with encoders;

3) Intuitive Working Process: Operator just need to key in control parameters at initiation of work period:

3. Related Equipment with Similar Purpose on Metal Structure Straightening:

1) ASM Series Angle Steel Straightening Machine: For straightening longitudinal deflection on single piece of Angle Steel;

2) RH Series Edge Rounding Machine: For deburring and removing sharp angles on edges of ribbed plate unit;

3) H Beam Straightening Machine: For straightening on flange or longitudinal deformation of H Beam.

B. Applicable Workpieces and Operation of J16 Reinforced Angle Ribbed Plate Straightening Machine:

1. Number of Angle Steels on Plate Unit:

1) It can be from 1 piece to several pieces on a plate unit, such as 5 pieces:

2) A piece of 5 Angle Stiffener Plate, levelled from Wuxi JACK J16 machine: (Fig.3)

3) Meanwhile, there are 3 sets of straightening units in a set of J16 model machine. So, the straightening units need to be adjusted on its lateral positions several times, to finish the leveling task;

2. Width of Reinforced Plate Unit in Reinforced Angle Rib Plate Straightening Machine:

1) Min. width request on the reinforced plate unit is 800mm;

2) Max. width of reinforced plate that can be fit into working zone of J16 model machine is 3000mm;

3. Thickness Range of Stiffening Plate Unit: From 6mm to 16mm. This is model “J16” got from;

4. Length Range of Stiffener Plate Unit: There is no restriction on the shortest and longest size. So long as it can be laid onto input and output conveyors of the J16 model machine;

5. Intervals of Angle Steel on the Ribbed Plate Unit: As mentioned previously, this adjustable interval of fabricated Angle Steels on the reinforced plate unit is from 450mm to 600mm;

6. Material of Rib Plate Unit: Most majority conditions, customer apply carbon steel ribbed plate unit. Of course, it can be any other available sheet metal, such as 16Mn/ Stainless Steel/ Alloy..., etc.;

7. Operation on J16 Reinforced Angle Stiffener Plate Straightening Machine:

All the main actions of the machine are controlled with advanced technique software and hardware integrated operating system in HMI station:

1) Primary Operating Interface of Wuxi JACK J16 model machine: (Fig.4)

a) All the main working motions of the machine are managed in this interface;

b) Such as: POWER ON/ OFF; Oil Pump Start ON/ OFF; Power Indicating Lamp; Straightening Units 1~3 Start ON/ OFF, etc.

2) Straightening Unit Interface: (Fig.5)

a) In this interface page, lateral movement and position of each straightening unit is precisely controlled;

b) Operator just need to key in corresponding process control parameters;

3) Hydraulic Station Interface: (Fig.6)

Purpose: Hydraulic system gives heavy force and reliable power on stiffener plate straightening operation.
