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

Quantity:

YTJ-40~50 hydraulic automatic H Beam flange straightening machine is the intermediate product category, connecting HYJ-series mechanical and YTJ-series hydraulic in terms of:

  - Medium straightening capacity of 40~50mm flange thickness for Q345 steel (Tensile strength is 

    510~600MPa);

  - Machine structure& Straightening process more close to mechanical HYJ-series, but in the same kind of

    hydraulic drive as YTJ-60~80


To be Specific,

  1) Web Positioning Unit

      Different from YTJ-60~80 hydraulic H Beam flange straightening machine (please check previous product, item

      2), secure of H Beam web is made with manual leadscrew at both sides of machine body.

     Please check picture as below:

 Web Positioning unit

     As can be seen from above,

     - There are 2 pairs of web positioning rollers at the front side and back side of main frame;

     - Each pair has left and right 2 sets of positioning rollers;

     - Each set has top and bottom 2 pieces of positioning rollers;

     - In all, for one set of YTJ40~50 hydraulic H Beam Flange straightening equipment, there are 8 pieces of 

       positioning rollers for Web clamping purpose;

     - Movement of these positioning rollers is made with handwheel at both sides of machine body, by way of 

       lead-screw;

     - HYJ-series mechanical high efficiency H Beam flange straighten machine has same structure

  2) Adjustment of the 2 top straightening rollers accommodating Flange width

      For YTJ40~50 hydraulic high efficiency H Beam flange straightening machine, this unit is also same as 

     mechanical HYJ, but different from YTJ-60~80:

T slot


      -  To have distance of the 2 pieces of top straightening rollers match with various width of H Beam flange 

         width, this straightening unit should be movable;

      - Instead of driven with oil cylinder as in the case of YTJ-60~80, movement of the straightening unit is realized

         with handwheel by means of leadscrew, along the T-slot at its beneath;

     - Do not make confusion with handwheels for clamping H Beam web mentioned in item 1. In the above picture,

       these 2 handwheels are the upper location of machine body

  3) Summary on full range of vertical mechanical and hydraulic H Beam flange straighten machine to make
