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 and YTJ-50 models are the intermediate product category, connecting HYJ series mechanical motor drive and YTJ series hydraulic drive in terms of:  

H Beam cross section orientation: (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 motor drive machines, but in the same kind of hydraulic drive as YTJ-60 and YTJ-80 models.

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

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

Different from YTJ-60 and YTJ-80 models, (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:  

Mechanical main body: (Fig.2)

2) As can be seen from above, in YTJ-40/50 models: (Fig.3)

a) There are two pairs of web positioning rollers at the front side and back side of 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 motor drive models machines 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 and YTJ50 models machine structure, this unit is also same as mechanical HYJ series motor drive structure, but different from YTJ60 and YTJ80 heavy duty ones:

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 and YTJ-80 models, movement of the straightening unit is realized with handwheel by means of leadscrew, along the T slot at its beneath:

3) Do not make confusion with handwheels for clamping H Beam web mentioned in item 1 with the handwheels here. In the above picture, these two handwheels are at the upper location of the machine main body.
