Edge Rounding machine and Stiffener Plate Straightening machine delivered for ZPMC

In early Apr. 2021, three sets of heavy-duty machine were shipped from Wuxi JACK Technology to a famous Chinese Port Machinery Group in Shanghai --- ZPMC (ZHENHUA Port Machinery Company).

 

  1. Constitutes and Application of the three machines:

   1.1The three delivered machines include:

    1)  One set of RH3000 Plate Edge Rounding machine;

    2)  One set of J28 Stiffener Plate Element Straightening machine;

    3)  One set of Steel Plate Overturning Racks.

   1.2 Application of the three machines:

    1) These machines are the essential equipment of a newly set up heavy duty Large

        Section Beam Production Line in ZPMC;

    2) The large section beams, usually with its size of cross section (1~ 1.5m) width

       by (1.5~ 3m) height in the length of (20 ~30m), are the basic raw materials in 

       manufacture of port machinery;

    3) These three machines take on the core steps of large section beam production

       shown in its process technology as below;

    1.3 The process technology of large section beam production:

     1) Plate sent in for cut;

     2) The cut plate is flipped with the Steel Plate Overturning Racks;

     3) The steel plate is sent to RH3000 Plate Edge Rounding machine for edge 

       deburring and trimming process, for improving its painting adhesion and 

       relieving stress;

     4) The plate is welded with stiffeners by means of welding robot, into the semi-

       finished product of Stiffener Plate Element;

     5) This stiffener Plate Element usually has deformation after welding. So, it is sent

       to the J28 Stiffener Plate Element Straightening machine for being straightened;

     6) The straightened Stiffener Plate Element is then sent to the final welding and

       assembling stations, to be made into a finished product of Large Section Beam.

 

   2. Usage and Strong Points of RH3000 Plate Edge Rounding machine and 

J28 Stiffener Plate Element Straightening machine:

   2. 1 Machine Usage:

     1) As can be seen from above, the three delivered machines play a key role in 

        construction of large section beams;

     2) The RH3000 Plate Edge Rounding machine is for deburring and rounding edge

      of steel plates. Its working principle is: The steel plate travels thru a cavity 

     formed with 4 pieces of straightening rollers, and got rounded into round edge 

      of R2.5mm at the same time;

     3) The J28 Stiffener Plate Element Straightening machine is for straightening 

      deform of the stiffener plate after welding. Its working principle is: Similar to 

      that of the RH3000 Plate Edge Rounding machine, the workpiece goes thru the

      clearance generated with 2 pieces of top straightening roller and 1 piece of 

      bottom straightening roller, and got straightened simultaneously;

   2.2 Machine Strong Points:

     1) Both the RH3000 Plate Edge Rounding machine and J28 Stiffener Plate

         Element Straightening machine is the largest product ever produced in 

         industry. There exists great challenge in its development;

      2) Its design and production embody the strong strength of Wuxi JACK 

         Technology.

In the process of development, Safety, Quality and Performance of the machines always take the first priority;

The design of the machines incorporates both practicability, ease of operation, durability, and good appearance;

Series of involved Chinese national standards are strictly conformed (For detail, please check the product section of “J-series Hydraulic High Quality Stiffener Plate Element Straightening machine”);

Design and manufacture of the machines strictly follow machine development process, and all the parameters and specification of the machines are carefully calculated and validated.

 

   3. Put into use of the RH3000 Plate Edge Rounding machine and J28 Stiffener Plate Element Straightening machine at customer site:

    1) The three machines were delivered to ZPMC and installed at their facility by 

      middle of Apr., 2021;

    2) After 2 weeks of on-site commissioning and trial run, the machines were put 

       into formal use since early May, 2021;

    3) Ever since, these three machines of RH3000 Plate Edge Rounding machine, J28

      Stiffener Plate Element Straightening machine and Plate Overturning Racks run 

     very smoothly, and got high approval and recognition by the customer of ZPMC.
