YTJ-40 Hydraulic Vertical High Precision H Beam Straightening Machine

Quantity:

YTJ-40 hydraulic high precision H Beam straightening machine is the “lightest” model of YTJ-series, for straightening Q345 (Tensile strength 510~600MPa) with thickness up to 40mm.

 

Its straightening principle is follows: (See below picture)

 Straightening principle- YTJ40 and 50

  1) For each set of these hydraulic automatic H Beam straightening machines, there are 2 pieces of top 

      straightening rollers and 1 piece of bottom straightening roller, composing a T-shape cavity. This is the

      critical section for performing straightening operation;

  2) During straightening, driven with hydraulic pump station, the two sets of upper rollers descend and press 

     H-beam flange with great force;

  3) With the action of top and bottom rollers, the flange has plastic deformation in the state of 3-points stress;

  4) Meanwhile, the bottom straightening roller rotates under the drive of motor reducer;

  5) In this way, H-beam is transported forward, going thru the T-cavity straightening area continuously along

     conveyor of this hydraulic high precision H Beam straightening machine, and its flange got straightened

     successively inside the cavity;

  6) With this process, one flange of the H-beam is rolled and straightened continuously along its entire length;

  7) If one time straightening does not straighten the flange to the required planeness, the 2nd straightening

     should be made with this hydraulic automatic H Beam straighten machine. But most of the condition, one time

     operation is sufficient to meet the target;

  8) The other side of flange is straightened in the same way. Which means, for one piece of H Beam, it needs to go

      thru this automatic H Beam straightening equipment 2 times to be straightened;

  9) The 2 pieces of top straightening rollers are of shaft-case structure, with great loading capacity;


 10) The 2 pieces of top straightening rollers are driven with hydraulic pump station by means of 2 cylinders. This is

      difference between hydraulic high precision H Beam straightening equipment with mechanical HYJ-series;

  11) With straightening speed of 9m/min., it is a kind of high speed H Beam straightening equipment;

  12) There are input and output conveyors at the front and back side of main frame of this hydraulic high 

       precision automatic H Beam straighten machine, for transferring H Beam into and out of the machine.
