J20 Stiffener Plate Element Straightening Machine for Port Machine

1.       Outline on J20 Stiffening Plate Unit Straightening Machine:

1)      The J20 Stiffening Plate Unit Straightening Machine for Port Machinery is the most often used model of its product group, which can meet the largest share of large section beam production;

2)      The max. thickness of stiffener end plate is 20mm;

3)      In this section we will have a discussion on structure and main components of J series (Including J20) Ribbed Plate Unit Straightening Machine;

4)      J Series Stiffened Plate Unit Straightening Machine works in the approaching way as Beam Longitudinal Straightening Machine.

2.       Structure and Constitutes of J series Stiffened Plate Unit Straightening Machine:

1)      Main Body of the Rib Plate Unit Straightening Machine:

As can be seen from attached and below picture, main body of the machine is a set of solid and sturdy gantry frame, with strong base bed and overhead platform: 

Mechanical main body of J20 Stiffening Plate Unit Straightening Machine: (Fig.1) 

2)      Column of the Stiffened Plate Straightening Machine Gantry Frame Main body:

a)       There are four pieces of upright round columns at the four corners of the gantry frame;

b)      These columns are made from seamless thick round pipes, which are welded with flanges, and assembled into the gantry frame thru the flanges by means of bolts;

3)      Advantages of Round Column for Gantry frame Main body of the Stiffening Plate Unit Straightening Machine:

The use of such round seamless pipes in the J series Ribbed Plate Unit Straightening Machine has two merits: 

The 4 pieces upright round columns in J series Stiffening Plate Unit Straightening Machine: (Fig.2)

a)       The first advantage is round column has the largest loading capacity which can withstand the impact from stiffener plate straightening process;

b)      The second advantage is round column gives the best appearance on the overall equipment of this Stiffened Plate Unit Straightening Machine;

4)      Bed and Platform of the Ribbed Plate Unit Straightening Machine:

The bed and platform of the gantry frame are made of high strength section steels and steel plates, with sufficient rigidity and stiffness, ensuring long term use of this Rib Plate Unit Straightening Machine;

5)      Straightening Units in the Stiffened Plate Unit Straightening Machine:

a)       There are three groups of straightening units assembled at the incoming side of the gantry frame;

b)      Configuration of Straightening Unit: For each group of the straightening unit, it is composed of two pairs of top straightening rollers, which are assembled together with its transverse driving motor into an assembly, and one piece of bottom straightening roller (Invisible in the attached, hidden by workpiece and supporting roller):

c)       During work of the Rib Plate Unit Straightening Machine, the top straightening rollers and bottom straightening roller are kept in-phase and coaxial all the while. Which means, for each group of straightening unit, its top rollers and bottom roller moves and stops in synchronization all along;

6)      Transverse Movement of Straightening Unit in the Stiffened Plate Unit Straightening Machine:

a)       During work, these straightening units can move leftward and rightward along overhead horizontal rail of the Rib Plate Unit Straightening Machine, accommodating various span of stiffeners on its plate element. The movement is motor reducer driven. See below:

b)      Detection: For precise positioning of the straightening units along transverse direction, there are rotary encoders installed for detecting actual position of the straightening units, making sure the J20 Stiffened Plate Straightening Machine always works accurately;

c)       Stroke Management: Besides, there are electric limit switches and rubber hard stops installed, for double insurance on transverse movement of the straightening units, making sure the Ribbed Plate Unit Straightening Machine always works safely;

7)      Pressing Bearing in the J series Stiffened Plate Unit Straightening Machine: (Fig.5)

The pressing bearing of the top straightening roller is critical component for guaranteeing normal operation of the Ribbed Plate Unit Straightening Machine. It has sufficient bearing capacity, and reasonable lubricating system;

8)      Supporting Roller in the Stiffened Plate Unit Straightening Machine:

a)       There is one piece of front and rear horizontal supporting roller respectively, assembled at the front and rear side of the gantry frame. Please check attached picture;

b)      Transmission of its revolve is coupled with that of bottom straightening rollers by way of chain and sprocket. See below:
