Feature of STL metal sheet strip straightener:
This is a special designed straightener for plane materials that need high precision punching treatment. As we all know, coil material can not produce good products without flattening and stress relieving treatments. therefore, the performance of the straightener is critical in the production process.
Since the cruvature of each point is different.it the difficult to reach high precision straightening requirement by only rectifying roll laying. STL adopts rough straightening for the wide rows, precision straightening for narrow rows and the diverse laying straightening principle. The rough straightening brings the material the bend arcs, then use the precise straightening to meet the customer punching requirement.
The flattening and straightening secondary wheels adopt the imported SUJ2,milling after HRC60 degree 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.
Adopts the high precision axis, and additional lubrication system prolongs machine life span.
Each straightening wheel of the S series precision straightener adopts the flatting satellite 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.
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.
