Description
The present invention relates to a roller lifting device of a tilting table for cutting a rolled material, and more particularly, the stroke is kept constant during the lifting (UP-DOWN) of the roller to prevent the phenomenon to be pulled to one side during product transfer, when cutting the product The present invention relates to a roller elevating device of a tilting table for cutting a rolled material to effectively maintain a squareness.
In general, the rolling process is a process in which iron is made of steel sheet or wire rod, and rolling is stretched by a continuous force in the process of passing through a plurality of rollers in which slabs, blooms, billets, etc. produced in a continuous casting process are rotated. Or thin forming process.
The rolling includes hot rolling at high temperature and cold rolling at low temperature.
Hot rolling has the advantage that the rolling power may be small, and the large deformation can be easily performed, and the rolled material can be given the same properties as the forged product.
Cold rolls, on the other hand, can be made very thin, provide good dimensional accuracy and clean surfaces.
An object of the present invention is to maintain a constant stroke during the lifting and lowering of the roller in the cutting process of the rolled material is prevented from being pulled to one side during product transfer, the roller of the tilting table for cutting the rolled material that can effectively maintain the squareness when cutting the product It is to provide a lifting device.
Roller lifting device of the first embodiment according to the present invention for achieving the above object is formed a plurality of first grooves on the upper surface, the bottom formed with a first pore for discharging the air to be compressed from the outside into the first groove plate; A plurality of head members placed on the first groove in contact with the bottom plate to form a first cylinder chamber, and having a first hole formed on an upper surface thereof; A first horizontal portion and a first vertical portion projecting vertically from the first horizontal portion and installed in the first cylinder chamber, and when air flows into the first cylinder chamber, an end portion of the first vertical portion extends from the first hole. A plurality of first pistons protruding; And a first sealing member installed at end portions of the first vertical portion to contact the roller of the tilting table for cutting the rolled material, and when the first vertical portions protrude, push the roller to protrude above the tilting table. .
The roller lifting apparatus of the second embodiment according to the present invention has a second cylinder chamber therein, a second hole is formed in the upper portion, and a second pore for introducing air compressed from the outside into the second cylinder chamber in the lower portion. Formed body; A second horizontal portion and a second vertical portion projecting vertically from the second horizontal portion, and installed in the second cylinder chamber, and when air flows into the second cylinder chamber, an end portion of the second vertical portion is removed from the second hole. Protruding second piston; And a second sealing member installed at an end of the second vertical portion to contact the roller of the tilting table for cutting the rolled material, and when the second vertical portion protrudes, pushes the roller to protrude onto the tilting table.
According to the present invention, the stroke is kept constant during the lifting and lowering of the roller to prevent the phenomenon of pulling to one side during the product transfer, it is possible to effectively maintain the squareness when cutting the product.
