D-Frame Single Crank Presses

Short Description:

STB-Series: 80~400 Tons

STB series presses is D-Frame single crank presses (Semi closed type), which is gap frame press with added support beams that helps to reduce the spring back and add more rigidity to the press frame. It allows heavier duty works to be performed than on a c-frame press.

STB series presses are produced by Qiaosen machinery, which built to meet or exceed JIS Class 1 accuracy standards. Qiaosen adopt high strength steel frames and Quenching & Grinding Process for Slide-Guide，which can make the press machine have minimizing deflection and high accuracy and provide increased tool life.

Forged 42CrMo alloy material crankshaft ，precision-machined gears and other drive train components are designed for smooth power transmission, quiet operation and long life. STB series presses are dry clutch system，It has longer service life of the clutch system ，high single stroke rate and high torque outputs performance. Flywheel direct drive design，which can be customized to shorter stroke, more faster speed.

Siemens based control platform and user-friendly touch screen operation interface are standardized in all QIAOSEN’s presses, it provides ease of operation and expandable capabilities. Easy to integration with other automation system. Other brands of control can be furnished upon request.
