High Efficiency Hydraulic Drive YTJ-50 I Beam Straightening Machine

1. Application of YTJ-50 Medium duty Hydraulic H Beam Straightening Machine:

1) Typical Applicating Site: This set of Wuxi JACK YTJ-50 model in the first photo was taken at a busy working steel structure facility. You can find from the photo that there are finished product of many welded H Beam, being laid on the workshop floor. There are other H Beam Production Machine in the far distance: A set of H Beam End Face Milling Machine;

2) Wide Use: YTJ-50 is the medium duty model of YTJ series hydraulic drive models, and also the often used type in metal structure industry;

3) Straightening Principle: YTJ-50 model has the same straightening principle as YTJ-40 Hydraulic I Beam Flange Straightening Machine. The difference between the 2 models lies in power of hydraulic cylinder, which in hence determines straightening capacity of the machine: (Fig.1,2) 

4) Note: YTJ-40 and YTJ-50 has similar straightening principle as HYJ series mechanical structure motor drive straightening machine. The difference lies in driving power source of the top straightening rollers: The YTJ-40 and YTJ-50 models are driven with hydraulic pump station, while the HYJ series H Beam Straightening Machine is driven with mechanical motor reducer.

2. Main units of Wuxi JACK YTJ-50 Hydraulic H Beam Straightening Equipment:

1) Mechanical main frame and base of Wuxi JACK YTJ50 model: (Fig.3)

This is the mounting bed and working area of the machine. All the important working elements are installed here;

2) Front side and rear side conveyor of YTJ series machine, with H Beam in erected orientation on conveyors roller tables: (Fig.4)

This units are for loading in flange deformed welding H Beam into the machine, and loading the straightened welding H Beam out of the machine;

3) Straightening roller unit of Wuxi JACK YTJ series H Beam Straightening Machine:  (Fig.5)

This includes two pieces of top position assembled straightening rollers, and one piece of bottom position assembled roller. These elements are the central execution mechanism of the YTJ series machine on H Beam straightening;

4) Hydraulic station of Wuxi JACK YTJ models machine, giving strong downward force on H Beam straightening:  (Fig.6)

This system includes hydraulic oil cylinders for pressing top straightening rollers downward. It is the energy source of the H Beam Straightening Equipment;

5) Bottom transmission unit of YTJ50 machine:  (Fig.7)

This is for driving on revolve of the bottom straightening roller, so that the welding H Beam can be transported forward together with its straightening process. In this way, the entire length of the welding H Beam can be straightened and sent forward going thru the YTJ50 model machine;

6) Motor reducer: This is for driving rotation of the input and output conveyors roller tables of the H Beam Straightening Equipment;

7) Web clamp unit at central function zone of Wuxi JACK YTJ50 machine: (Fig.7)

This unit includes two pairs of aligning rollers at front and back side of the main frame each. It for clamping web of H Beam during straightening period in the H Beam Straightening Machine;

8) Control board and operation station of Wuxi JACK YTJ50 model:  (Fig.8)

As a kind of automatic H Beam Production Machine, all the working actions of the YTJ series are manipulated with this operating station.

3. Technical Specification of YTJ-50 H Beam Flange Straightening Machine:

1) Main transmission system of the YTJ-50 (YTJ-40 also) models is adopted with 15KW motor and driven with gear speed reducer, of high transmission efficiency and rapid straightening speed (9m/min.);

2) Operation of YTJ-50 high speed H Beam Straightening Machine:

a) Control board is put on the ground, away from the machine main frame;

b) For the purpose of convenient operation, operating panel is installed on the main frame close to the core T shape cavity straightening section;

c) Operating panel of YTJ40 and YTJ-50 models see below picture (Due to different straightening principle, operating panel of YTJ-60 and YTJ-80 Hydraulic I Beam Flange Straightening Machine is different from YTJ-40 and YTJ-50):

Operating panel of Wuxi JACK YTJ50 (And YTJ40) model machine: (Fig.9)
