Rolling Process is a critical manufacturing method used to produce threaded fasteners like screw, bolts, and studs. This process involves transforming a cylindrical blank or rod into a screw by forming threads along its length.
Blank Preparation: The chosen blank material is first loaded into the vibrator feeder. These blanks serve as the starting point for creating the screw threads.
Feeding and Positioning: The blank is fed into the thread rolling machine and accurately positioned between the rolling dies. Proper alignment is crucial to ensure uniform thread formation.
Cold Forging: This process involves shaping a metal blank or workpiece into the desired screw shape using compressive forces at room temperature (or slightly elevated temperatures). Cold forging is a highly efficient and precise method for producing screws, and it offers several advantages, including improved material properties and reduced material waste.
Thread Rolling Operation: The machine’s moving die applies significant pressure to the blank, causing it to deform plastically and take on the shape of the threads within the fixed die. This process displaces material from the blank into the thread profile, effectively creating the threads. The rolling process is highly precise, and it produces threads with excellent strength and surface finish.
Quality Control: Quality control measures are crucial at every stage of the manufacturing process to ensure that the screws meet the required specifications and standards. This may include inspecting thread geometry, diameter, and surface finish.
