Innovative solutions, a new concept in screw rolling centers, eliminating manual work, that is, complete computerization.

This screw rolling center features a proven proprietary feeding system that is effective for stud bolt production. The blanks are supplied to just before the starter finger via tube-based transport, and then the blanks are accurately fed to the processing section by a pneumatic feeding device. Two types of specifications can be adopted for precise blank orientation control. • The specification suitable for maximum productivity connects the screw rolling machine to a header, supplying forged blanks directly to the rolling machine via a transport tube. • The other specification utilizes a vertical or vibration feeding system according to the product length, along with mechanical control for orientation using image analysis with a digital camera, and a cutting supply system.

SACMA Group's "Cold Former," a productivity-enhancing solution that the world can be proud of.

The blank transport mechanism of the SACMA company's progressive die former has become a world standard after years of consideration, addressing issues that have been typical failure examples from other manufacturers. The precise configuration of the transport fingers is established by a mechanism that enables smooth oscillation motion and a desmo cam (double cam) system that allows for perfect positioning control and maximum production speed. The multi-adjustment of transport timing phases, along with variations in the clamping force of the clamp fingers and the opening and closing speed of the fingers, allows for safe and maximum-speed transport of blanks ranging from long to short lengths, even without the use of springs.

Pointing, screw rolling (flat die) with a composite station, high reliability and productivity of SACMA machinery.

Pointing, Thread Rolling (Flat Die) Composite Station From the final forming station, the forming blank is first transported to the pointing station via a finger-type conveyor elevator that allows for easy adjustments according to the shape and size of the forming blank. The adjustment mechanism is composed of a "micrometric" system that is easily accessible and readable by the operator. The forming blank is fed into the pointing unit at the tip processing station, where the tip processing is carried out. Various shapes and angles of tip processing are possible, including the commonly used tip angle of 90° in the automotive industry. The blank is then transported from the pointing station to the next flat die thread rolling station. The thread rolling station is equipped with flat dies, and to accurately insert the forming blank between the flat dies, a stopper gate and a single starter blade system are installed at the end of the guide rail, following the alternating movement of the main slide. Optimal adjustment of the thread profile shape is achieved using the eccentric adjustment section on the drive connection rod of the slide and the vertical adjustment wedge for the flat die mounting section.
