Socket Cap Screw Production Process
1wire is fed from a wire coil through a drawing machine, then the straightened wire flows directly into a cutting machine that will be cut automatically into pieces at a designated length and die will cut the head of screw blank into a predefined shape. The heading machine will utilize an open or closed die to give one punch or two punches to create the screw head. The closed die can create a more accurate screw blank. The heading machine can produce 200 to 500 screw blanks per minute.
Once the wire was colded headed.the screw blanks will be automatically transferred to the thread-cutting dies from a vibrating hopper. The hopper then guide the screw blank down to the dies. But be sure they are in the correct feed position.
The it come to the cutting process, the headed screw blanks are normally cut by two reciprocating die , one die is stationary, the other one moves in a reciprocating way sothat the screw bland is automatically rolled between two dies. Besides the centerless cylindrical die can also be used the screw blank then is rolled between three round dies in order to create finished thread. The last way of thread rolling technique is to sue the planetary rotary die . in this way the screw blank is held stationary in the process that the die cutting machines roll around the blank.
Once the screw blank rolled and thread is created , then it come to the surface treatment . the threaded screw nail will be fed to the polishing machine , where the thread screw nail will be polished to have a nice looking on the surface.
