Hydraulic High Power YTJ-60 H Beam Flange Straightening Machine

Without workpiece laid in the machine, as shown in the first photo, the YTJ-60 Hydraulic H Beam Straightening Machine looks ordinary. Only after the large thickness H Beam straightened in it, can we identify the extraordinary of this H Beam Production Machine.

1. Outline on YTJ-60 Hydraulic H Beam Straightening Machine:

1) The YTJ-60 (and YTJ-80) are heavy duty products of YTJ series H Beam Straightening Equipment;

2) To be specific, although all the models work in the manner of hydraulic drive, the YTJ series I Beam Straightening Machine (Here I Beam is the same name of H Beam) can be divided into two sub groups of light and medium duty of YTJ-40 and YTJ-50 Hydraulic H Beam Straightening Machine, as well as heavy duty YTJ-60 and YTJ-80 models;

3) The Dividing Line between the above mentioned two sub-divisions hydraulic H Beam Straightening Machine are reflected on the aspect of:

a) Different specific straightening principle between the light and medium duty, with heavy duty hydraulic models;

b) Hence structure and operating process (Operation panel) of the two types of hydraulic H Beam Straightening Machine.

2. Comparison and Analysis on YTJ-60(And YTJ-80) with YTJ40 and YTJ-50 High Power Hydraulic H Beam Straightening Machine:

Below sketches illustrates on comparison on straightening principle between the two sub groups: (Fig.1,2)

YTJ-40 and YTJ-50                      YTJ-60 and YTJ-80

1) Difference of T shape Cavity in the two Sub Division Hydraulic H Beam Straightening Machine:

a) As can be seen from above the two sketches, with the same kind of T shape cavity formed with two pieces of top straightening rollers and one piece of bottom straightening roller, for YTJ60 and YTJ-80 high power hydraulic models, working style is bottom straightening roller moving upward and exerting force on bottom of the flange tightly, while the two pieces of top rollers kept at static along vertical direction;

b) This is contrary to that of YTJ-40 and YTJ-50 Hydraulic H Beam Straightening Equipment, as well as HYJ series mechanical models;

2) Similarity of Straightening Force in the two Sub Division of Hydraulic H Beam Straightening Machine:

Same as YTJ-40 and YTJ-50 models, the driving power on bottom straightening roller is from hydraulic cylinder, with higher power and hence greater driving force;

3) Difference of Forward Driving in the two Sub Division Hydraulic H Beam Straightening Machine:

Also contrary with YTJ-40 and YTJ-50 models, in YTJ60 and YTJ80 models, forward transportation of welding H Beam on the conveyors is made with revolve of the two pieces of top straightening rollers, instead of the bottom roller as in the case of YTJ-40 and YTJ-50 models;

4) Difference of Machine Structure in the Two Sub Division Hydraulic H Beam Straightening Machine:

The span adjustment unit for the two pieces of top straightening rollers is different. Please check below picture: 

Straightening roller adjustment in H Beam Straightening Machine: (Fig.3,4) 

    YTJ-40 and YTJ-50                              YTJ-60 and YTJ-80

a) For accommodating flange of various size, it is necessary to adjust relative position of the two pieces of top straightening rollers. In YTJ60 and YTJ80 models, such movement of the upper straightening rollers is driven with oil cylinder within guiding bush;

b) While in YTJ-40 and YTJ-50 (Also mechanical structures), such movement on span adjustment is made with handwheel along a T slot;

5) Operating Panel of YTJ-60 high power hydraulic H Beam Straightening Machine:  (Fig.5,6)

a) With both the top straightening rollers and web clamp unit are all driven with hydraulic cylinders, instead of mechanical leadscrew by means of handwheel as in the YTJ-40 and YTJ-50 hydraulic drive models, operation of the YTJ-60 (And YTJ-80) models integrates corresponding buttons for fulfilling these tasks;

b) Please check attached the sixth picture on operating panel and above sketch. It is in Chinese. For specific meaning and usage of each button, please check introduction on YTJ-80 high power Hydraulic H Beam Straightening Machine.
