A. Application of J and JF Series 2 Types of Plate Straightening Machine:
Where Used of these machines:
a) In the field of Port Machinery/ Shipbuilding industry/ Hoist Crane/ Large Scale Bridge, there are some minority used machines, which aims on producing the workpieces/ assemblies only applied in these industries. In other words, these are tailor made equipment;
b) Among these, there are 2 types of important but small volume applied machines:
1) The other name of the machine is: Angle Steel Ribbed Plate Straightening Machine, which is used for straightening on welded Ribbed Plate Element/ Stiffeners Plate Element;
2) These stiffener plate units are important working parts, for producing large section Beam. These large section Beams are indispensable assemblies of finished large machinery and constructions;
3) At a Chinese customer facility, a piece of long stiffener plate unit, being straightened in Wuxi JACK J28 model Angle Steel Stiffening Plate Straightening Machine: (Fig.1)
2. JF Models Plate Butt Welding Seam Straightening Machine:
1) Background: In these industries, large size steel plates are necessary, which, the conventional steel plates from Still Mill do not have required dimension. So, expected sized steel plate will joint, from MP model Plate Butt Joint Welding Machine;
2) After the plate joint, sometimes butt joint welding seam will bulge up, caused from heat input effect from large current SAW (Submerged arc welding), which should be flattened with JF model machine:
3) A piece of joint plate was flattened with Wuxi JACK JF16 Plate Butt Welding Seam Straightening Machine: (Fig.2)
B. Brief on Application of J16/ J20/ J28 Angle Steel Stiffening Plate Straightening Machine:
1. Workpieces of Angle Steel Stiffened Plate Straightening Machine:
1) The plate welded with one to three or more pieces of Stiffener/ Rib, in the form of Angle Steels, which are applied as raw materials for making Large Section Box Beam, which in turn is used for manufacturing Port Machinery or Hoisting Machinery, or Bridge Construction:
a) A piece of typical Angle Stiffener Plate after straightening from J models machines: (Fig.3)
b) These reinforced plate unit is formed, with several pieces of Angle Steels, to be welded onto base steel plate: (Fig.4)
2) The standard width of workpieces (Angle steel Ribbed Plate/ Stiffener Plate) processed in machine have length up to 3,000mm, which can meet on majority of practical application;
2. What can Angle Steel Ribbed Plate Straightening Machine do for Customer?
1) In the process of large section beam manufacture, the Ribbed Plate/ Stiffener Plate usually grow deformed along its end plate, after the end plate being welded with Angle steels. Such deformation should be straightened with heavy force, for the purpose of getting stress relief and keeping sufficient strength;
Angle steel stiffener plate straightening trial operation, in Wuxi JACK J28 model machine: (Fig.5)
2) Put into Use: The J series Angle Steel Stiffened Plate Straightening Machine is developed by Wuxi JACK engineering team for this purpose. It can be worked as an equipment in Large Section Beam Production Line, working together with other equipment, such as Edge Rounding Machine, and Edge Milling Machine; Or operated as individual equipment, boosting more flexible use:
Wuxi JACK J16 model on stiffener plate straightening, works at customer facility: (Fig.6)
C. Technical View on Angle Steel Ribbed Plate Straightening Machine and Plate Butt Welding Seam Straightening Machine:
1. Straightening Units in Two Types of Plate Straightening Machine:
The 2 types of machines have similar straightening working principle, and similar and but different straightening units:
1) The 3 groups of straightening mechanism, in Wuxi JACK J16/ J20/ J28 models machines, on ribbed plate unit straightening operation: (Fig.7)
2) The straightening unit in Wuxi JACK JF16 model machines, on butt joint plate welding seam straightening operation: (Fig.8)
3) Quantity: Shown in the above two photos, in each set of machines, the straightening units here has one to three groups of straightening rollers;
4) Structure: Of which, each group consists of 2 pairs of up position downward moving straightening roller, and 1 piece of bottom position stationary straightening roller;
5) Drive Force: The downward straightening stroke of these rollers are driven with hydraulic oil cylinders, of reliable heavy force;
6) Such design of straightening unit structure can meet practical application at customer site;
2. Models of J Series Angle Steel Stiffening Plate Straightening Machine:
1) 3 Common Seen Models: Based on thickness of end plate of workpiece, the J series machine can be classified as: J16, J20 and J28, for straightening Rib Plate/ Stiffener Plate with its end plate thickness of up to 16mm, 20mm and 28mm respectively;
2) In this product section of J series (Including J16, J20 and J28) models, we will give introduction on all the standard models of the machine;
3) Meanwhile, besides standard models of these machine, we can also design and produce tailor made models, based on customer demand;
3. Operation on 2 Types of Plate Straightening Machine:
1) User Friendly Operation: Based on Wuxi JACK strong and leading technical strength, our engineering team develops intuitive and convenient HMI (Human machine interface), as operating media. This helps operators grasping on machine operation monitor in more efficient and effective manner:
2) Colored HMI operating station of Wuxi JACK J models Angle steel stiffener and JF models butt seam welding Plate Straightening Machine: (Fig.9)
