AI Technical Summary
In existing cold heading machines, deformed steel is difficult to handle during bolt production, resulting in low processing efficiency. Furthermore, the noise generated during the cold heading process can damage the eardrums of operators.
A structure including a drive motor, a double-threaded screw, a movable plate, a connecting rod, and a cylindrical block was designed. The drive motor drives the double-threaded screw to rotate, which causes the movable plate and connecting rod to move the lifting plate upward. The cylindrical block inserts into the mold cavity and pushes out the deformed steel, solving the problem of inconvenient steel handling. At the same time, the noise during the cold heading process is reduced through the cooperation of the transmission motor, transmission shaft, rotating rod, and soundproof cover.
It enables convenient handling of deformed steel, improves processing efficiency, and enhances the working environment for operators through noise reduction design.
