The diameter of the internal diameter and wire rod of stating through hole is adapted, and the center of fixed block is provided with an annular knife blade, the annular knife blade
Internal diameter is consistent with the internal diameter of through hole, and the annular knife blade is arranged on the inside of fixed block by a hollow connecting shaft, and
The connecting shaft is provided with belt pulley I, and the belt pulley I is connected by belt I with the cutting motor at the top of fixed block.
Preferably, fixed block is divided into left and right two parts, respectively left fixed block and right fixed block, the both ends of the connecting shaft
It is connected respectively by bearing with left fixed block, right fixed block.
Preferably, it is provided between left fixed block and right fixed block in the top position of belt pulley I between being passed through for belt I
Gap.
Preferably, draw-gear includes the driving wheel and driven pulley for drawing, the driving wheel and driven pulley
Wheel rim is respectively provided with the race by wire rod, and the driving wheel and driven pulley are pacified by driving shaft and driven shaft respectively
On support, driving gear is installed on the driving shaft, driven gear, driving gear and driven tooth are installed on driven shaft
Wheel is intermeshed, and a belt pulley II is also equipped with the driving shaft, and the belt pulley II passes through belt II and traction
Motor connection.
Using above-mentioned technical proposal, the present invention passes through the traction of draw-gear so that wire rod by the through hole of fixed block,
Because the diameter of through hole and the diameter of wire rod are adapted, thus when wire rod passes through through hole, by being acted on through pore pressure force,
The place stretching, extension for making wire rod not straight stretches, so as to improve the linearity of wire rod, while the cutting for passing through circular shear blade so that wire rod
Upper unnecessary part is cut so as to keep the flatness of wire rod, and then improves the qualification rate of product.
