HYJ-series Conventional Mechanical Automatic H Beam Flange Straightening Machine

HYJ series Mechanical H Beam Straightening Equipment has wide application in steel structure industry. The attached photos show its put into use at customer site, as well as production in batch at Wuxi JACK.

1.     Scope of HYJ series Mechanical H Beam Straightening Machine:

1)      This product refers to sub category of mechanical drive automatic I Beam flange straightening machine (I Beam has the same meaning as H Beam), including HYJ-40 and HYJ-800 standard model, as well as other custom made product;

2)      In application of H Beam Flange Straightening Machine after H Beam Submerged Arc Welding Machine, this type of product accounts for 60%~70% usage. This is the reason it is given the name of Conventional H Beam Flange Straightening Machine.

2.     Usage of the HYJ series Mechanical H Beam Straightening Machine:

1)      The HYJ series Mechanical H Beam Flange Straightening Machine utilizes the theory of “Three points being stressed in a T shape cavity”, and uses A.C. motor as its driving force, as well as three pieces of straightening rollers as its executing elements, to straighten the up bending deformed flanged of welding H Beam:

2)      Nearly all the automatic H Beam Production Line adopts with HYJ series Mechanical I Beam Straightening Machine, either HYJ-40, or HYJ-800;

3)      The product can also work in semi-automatic H Beam production line, or as an individual equipment of automatic I Beam flange straighten machine;

3.     Straightening Principle of HYJ series Mechanical H Beam Straightening Machine:

Please check sketch as below:  

Straightening principle illustration and straightening rollers in H Beam Flange Straightening Machine: (Fig.2,3)

1)      Mechanical H Beam Straightening Equipment has similar straightening process as medium duty hydraulic YTJ40 and YTJ-50. For detail please check product introduction of Vertical Position YTJ40 Hydraulic I Beam Flange Straightening Machine;

2)      The only difference between HYJ series Mechanical H Beam Straightening Machine and YTJ series hydraulic type is, driving power source on the two pieces of top straightening rollers is motor reducer, instead of hydraulic station by way of oil cylinder as in the case hydraulic H Beam Flange Straightening Machine:

4.     Straightening Capacity of HYJ series Mechanical H Beam Flange Straightening Machine:

1)      For HYJ series mechanical I Beam flange straighten machine, its limit on straightening flange thickness for Q235 (Tensile strength 370~ 510MPa) is 40mm;

2)      For 16Mn material, the straightening speed is 70％ of same thickness of Q235-A.

5.     Machine Structure and Size of HYJ series Mechanical H Beam Straightening Machine:

Below is sketch of main body and conveyor of HYJ series automatic Mechanical H Beam Straightening Machine: (Fig.5) 

1)      Both HYJ-800 and HYJ-40 Mechanical H Beam Straightening Equipment has machine size of around 3.5m L x 1.1m W x 1.7m H;

2)      Standard configuration of the HYJ Mechanical I Beam Straightening Machine includes 10m length input and output conveyor each. Customer can also prepare the conveyor by themselves, excluding it from supply range of the H Beam flange straightening machine;

3)      Weight of the standard model HYJ H Beam Straightening Machine is around 7~8 Ton;

4)      Straightening Rollers of HYJ Mechanical H Beam Straightening Machine:

a)       For workpiece (H Beam) straightened in HYJ-800 H Beam Straightening Machine, the allowable smallest web height is 350mm;

b)      If web height is within the range of 160 ~300mm，and flange thickness≤14mm，assistant straightening roller will be used in the H Beam Straightening Machine: One set of assistant straightening roller is prepared as delivery.

6.     Operation of HYJ series Mechanical H Beam Straightening Machine:

1)      Operating panel of HYJ series mechanical H Beam Flange Straightening Machine has similar operation as that of medium duty hydraulic I Beam Straightening Machine YTJ-50 and YTJ-40. Please check below on panel of the machine exported to Russia:  

Operating panel of H Beam Flange Straightening Machine: (Fig.6)

2)      Difference between operating panel of mechanical H Beam Straightening Machine with hydraulic is, mechanical type does not have control on hydraulic oil pump.
