AI Technical Summary
In the traditional manufacturing process of hexagonal head screws, the raw material needs to be manually or pneumatically pushed and squeezed into the molding die, which can easily lead to insufficient or excessive external force, resulting in a low production qualification rate.
By employing a stepper motor and a rotation sensor in conjunction with a displacement cylinder and a limit switch, the number of rotations of the lead screw and the extension and retraction length of the displacement cylinder are monitored in real time, precisely controlling the distance between the bottom mold and the top mold to ensure appropriate external force is applied.
This improved the yield rate of internal hexagonal head screws and avoided product quality problems caused by improper application of external force.
