Pinch Roll & Tail Breaker

We are a leading manufacturer of Tail Breaker that is made from high-quality raw material and advanced technology.

The pinch rolls are cantilevered and the top roll is raised or lowered pneumatically. The pinch rolls function is to drive the bar through dividing shear after it leaves the finishing stand. Also these are used one each for crop and cobble shears. The pinch rolls assemblies rotate in chocks housed in fabricated frames and are driven through D C Motors through gear box and the Cardan shafts.  The roll size varies from 250 mm to 550 mm depending upon the requirement of the mill.

We manufacture Cantilever and pneumatic type Pinch Roll & Tail Breaker up to 550 MM CRS. The Top roll is raised pneumatically or lowered with bottom roll in the adjustable to pass-line. The Pinch roll housing has sturdy welded construction, which feature wear resistant surface with anti-friction bearing mounting support and the use of sensors that allows precision breaking up to the speed of hot bar material.The signal in case of breaking pinch roll is received from DC Motor of Dividing shear for actuation. There are two DC Motors driving each set of breaker pinch rolls. There is selector switch which guides the bar to one of the two channels. The tail breaker pinch roll reduces the bar speed so that it stops within the twin channel. 

Pinch Roll Consists of two rolls to pull the material, when it has left the stand and pushed into the next stand, quenching box or the next processing equipment. The top roller can be approached or moved away by means of a pneumatic cylinder. The bottom roller is adjusted in height with a screw-down system to suit the rollers position to the bar dimension. The steel housing is perfectly oil-tight. Forced lubrication system for gears and bearings of pinch roll designed for connection with an out- side system under pressure. The pinch rolls get signal through HMD (Hot metal Detector) through PLC. The HMD placed ahead detects the front end and transmits signal.
