<h2> Pinch roll  for tmt bar/rebar/round bar/wire rod plant </h2>

Pinch roll introduction:

Equipment Use:

    Pinch roll is used to clamp the rolled pieces and sent them into the laying head, can pinch entire process as well as pinching head and end.Meanwhile, laying head in a circular motion to spin the rolled bar sent by pinch roll into a diameter 1250mm coil ,then the coils drop into the disperse coil cooling conveyor.

Structural performance:

    Pinch roll and laying head are the next two relatively independent parts.Pinch roll is horizontal cantilever roll structure, double roll driving together,the cylinder control upper and lower roll,and meanwhile clamping.Pinch rolls driving by a DC adjustable-speed motor through two cylindrical gear growth.Laying head is the horizontal arrangement, Slopes downward 15 degrees. It consists of spinning pipe which is installed in the rotating spindle and transmission. Rotating spindle is driving by one DC adjustable-speed motor by a pair of bevel gear wheel.Spinning pipe can spin the required outer diameter coil according to setting speed rotating.Laying head transmission gear box used welding structure. The gear and bearings in the box body adopt to thin oil central lubrication.Spinning head is cover in the laying head shell.The shell is cylinder structure, tilted arrangement as well to play a role of protection. The top half can been controlled to open by the hydraulic cylinder, which operation is to changing the spinning pipe. But it must be closed at regular work.
