In this section of J-Series Ribbed Plate Element Straightening machine, we will give general outline on this equipment on the aspect of its Origin/ Usage/ Nomination/ Working principle.
1) Large Section Beam or Large Section Box Beam:
In manufacturing Port Machinery or Hoisting Machinery, it is usually necessary to use such raw material: Width
of cross section is 1~1.5m; Length of cross section is 1.5~3m; Length is 20~30m. To make it strong enough,
these large section beams are made of Ribbed Plate Element, or Stiffener Plate Element;
2) Ribbed Plate Element or Stiffener Plate Element:
Please see attached picture. A steel plate welded with one ~ three or more stiffeners or ribs, to make it into a
welded plate element of sufficient rigidity, for the next step of producing large section beam or large section
box beam.
That after welding the stiffeners/ ribs onto the plate, these ribbed plate elements or stiffener plate elements
usually exhibit deformation, which should be straightened for next step process. Henceforth, the J-series
Ribbed plate element straightening machine is for straightening welded and deformed Ribbed plate
element /Stiffener plate element.
Its workpiece of Rib Plate and Stiffener Plate is equivalent and can be exchanged. Besides, for its finished
product and application industries, there are several names with this machine. Enumeration as below:
1) Stiffener Plate Element Straightening machine for Port Machinery;
2) Rib plate element straightening machine for Port Machinery;
3) Stiffener Plate Element Straightening machine for Large Section Beam;
4) Ribbed plate element straightening machine for Large Section Beam…
Please check attached picture.
1) The machine adopts working way of workpiece passing thru its main body, and got straightened at the
same time;
2) Each of the straightening unit is the combination of two pieces of top straightening rollers and one piece
of bottom straightening roller;
3) During working, workpiece travels thru the clearance between the top and bottom rollers, and straightened
at the same time;
4) There are three straightening units equipped with one set of Stiffener Plate Straightening machine. So,
up to three pieces of stiffener plate / rib plate can be straightened simultaneously.
