YTJ-40~50 Hydraulic High Efficiency Automatic H Beam Flange Straightening Machine

1.     Position of YTJ-40/50 Hydraulic H Beam Straightening Machine:

YTJ-40/50 automatic Hydraulic H Beam Flange Straightening Machine is the intermediate product category, connecting HYJ series mechanical H Beam Straightening Machine and YTJ series hydraulic H Beam Straightening Machine in terms of:  

H Beam cross section in H Beam Flange Straighten Machine: (Fig.1)

1)      Medium straightening capacity of 40~50mm flange thickness for Q345 steel (Tensile strength is 510~600MPa);

2) Machine structure and straightening process more approach to mechanical HYJ series I Beam Straightening Machine, but in the same kind of hydraulic drive as YTJ-60/80.

2.     Structure Analysis on YTJ-40/50 Hydraulic I Beam Straightening Machine:

1)      Web Positioning Unit in the H Beam Straightening Machine:

Different from YTJ-60 and YTJ-80 Hydraulic H Beam Flange Straighten Machine (please check previous product, item 2), after adjusting span between the two top straightening rollers, secure of H Beam web is made with manual leadscrew at both sides of machine body;

Please check picture as below:  

Main body of Hydraulic H Beam Flange Straighten Machine: (Fig.2)

2)      As can be seen from above, in YTJ-40/50 Hydraulic H Beam Straightening Machine: (Fig.3)

a)       There are two pairs of web positioning rollers at the front side and back side of I Beam Straightening Machine main frame;

b)      Each pair has left and right two sets of positioning rollers;

c)       Each set has top and bottom two pieces of positioning rollers;

d)      In all, for one set of YTJ40~50 Hydraulic I Beam Flange Straightening Machine, there are eight pieces of positioning rollers in total for Web clamping purpose;

e)      Movement of these positioning rollers is made with handwheel at both sides of machine body, by way of leadscrew;

f)        HYJ series mechanical high efficiency H Beam Straightening Machine has same structure as above for this mechanism.

3.     Adjustment of the Two Top Straightening Rollers Accommodating Flange Width in YTJ-50/60 Hydraulic H Beam Straightening Machine:

For YTJ40/50 high efficiency hydraulic H Beam flange straightening machine, this unit is also same as mechanical HYJ series H Beam Straightening Machine, but different from YTJ-60/80 hydraulic H Beam Flange Straighten Machine:

1)      To have distance of the two pieces of top straightening rollers match with various width of H Beam flange width, this straightening unit should be movable;

2)      Instead of driven with oil cylinder as in the case of YTJ-60/80 Hydraulic I Beam Flange Straightening Machine, movement of the straightening unit is realized with handwheel by means of leadscrew, along the T-slot at its beneath:
