Feature of SPS metal sheet strip straightener:

This is a special designed straightener for medium thick products that need improving the high precision punching treatment. As we all know, coil materials can not produce good products without the flattening and stress relieving treatments; therefore, the performance of the straightener is critical in the production process.

The flattening and the straightening secondary wheels adopt the  imported  SUJ2, milling after HRC60°heat treatment and starts production after plating the hard chrome to ensure evenness of the chrome layers and the form tolerances of each bearing.

The flattening adjusting adopts floating four-point balancing equipment, with the dial indicator, which can find the leveling point rapidly.

Adopts the cardan joint and the gear transmission, suitable for straightening high precision requirement products.

Except the straightening roller the additional feeding wheel improves the punching precision.

Adopts the high precision axis, and the additional lubrication system prolongs machine life span.

Each straightening wheel of the S series precision straightener adopts the flatting satellite wheel to prevent the distortion in the manufacturing process from happening, which improved the products flatness quality.

With the fixed top and bottom secondary roller enhanced the top and bottom wheel rigidity and prevent it distorts.

The triplication and the transmission structure adopts the synchronous style to transfer each leveling roller individually to lower the panel surface flatness improving requirement because of the interspaces caused by wheels rotating.

Due to the differences of the material quality, width and thickness, there are no fixed values as the preferences; therefore, taking some materials for pilot run before the mass production and start the continuous assembly after it reaches the standard.
