RH-1500 Plate Edge Rounding Machine for Shipyard Industry

Quantity:

The RH1500 Edge Rounding machine, although only 500mm wider than RH1000, has completely different machine structure. Or, as we mentioned before, RH1500/ RH2000/ RH3000 share the same equipment construction in RH-series automatic Edge Rounding equipment.

 

   1. Technical Features of RH1500 Edge Rounding machine for shipyard:

   1) 1500mm is the threshold for the issue of center drum up happened on workpiece during rounding process;

   2) The definition on “center drum up” is: During edge deburring and rounding of workpiece with the both

     sides of rounding rollers, the middle of workpiece (Especially plate, compared with T Beam or H Beam) is prone

    to be drummed up under the effect of both sides rounding force;

   3) This is the reason for RH1500 and above (RH2000/ RH3000) high power Edge Rounding machine, there is a 

     set of downward pressing rollers, composed of one ~ three downstroke rollers, to be pressed against top 

     surface of workpiece tightly during rounding process, preventing the middle of workpiece from being drummed

     up;

    4) Same as other actions of this Edge Trimming machine, the above-mentioned downstroke press rollers are also

      driven with hydraulic cylinders;

    5) Different from RH1000 Edge Trimming machine, the transverse movement of rounding rollers at both sides,

      is in the form of automatic center alignment. Which means, under the effect of its driving oil cylinders, both 

     sides of rounding rollers can be moved toward workpiece, or away from it, to be suitable for varying width of 

     workpiece;

    6) Same as RH1000 Edge Rounding equipment, leftward& rightward movement of the rounding rollers of

      RH1500 automatic Edge Rounding machine are guided with guiding rod& bush, which is made of precision

     -processed 45#steel and plated with Chromium. This fully guarantees positioning accuracy of this high precision

      product;

    7) The entire set of RH1500 Edge Trimming machine has construction of integral frame structure. Please check

      attached picture. There are four columns fit at the four corners of machine bed, which are assembled into an 

     integral frame body with the two pieces of long “lying” column and two pieces of short cross-beam 

     overhead. This gives a very firm and sturdy machine constructure, which fully guaranteeing reliable and 

     consistent working process of this high speed Edge Rounding equipment.
